Taxonomy is the study of organisms, their classification into categories, and their evolutionary relationships. Taxonomy is based on systematics. Systematic considers morphological characters, as well as physiological, cytological, molecular, and behavioral characters.
Categories are according to the organism's morphological and molecular characteristics. In hierarchical order, the categories are:
Kingdom: Includes different phyla closely related. Phylum: Includes different classes closely related.Class Includes different orders closely related.Order: Includes different families closely relatedFamily: Includes different genera closely relatesGenus: Includes many species.Species: Includes subspeciesDomain is a final classification that includes all groups.
There are two ways to identify species:
→ Using a binomial name
These names are composed of genus and species Are universal names ⇒ can be used at a global level.→ Using common names
They vary according to popular knowledge Might vary among regions ⇒ One species can have more than one name Can not be used for global identification.------------------------------------------------------------------------------------

White blood cells engulf bacteria through what process?
Answer:
Phagocytosis
Explanation: Phagocytosis occurs in the scavenging white blood cells of our body. They prowl around looking for invading bacteria and viruses which they engulf and destroy. Pinocytosis ("cell drinking") is almost the same process as phagocytosis, except it involves liquids instead of solids.
Conservation of Mass Activity Worksheet
Instructions: Observe and analyze the interactions between the substances pictured in the slide show. Compare the properties of substances before and after each interaction. You will submit your completed worksheet for grading.
Data Table
On the table below, record your observations before and after the interactions and explain how mass was conserved. Describe the changes in properties that prove a chemical reaction occurred. The first row is an example.
Observations Before Interaction Observations After Interaction How was mass conserved? Proof of a Chemical Reaction
Example: Sugar + Heat The sugar is in tiny white particles in a pile. Heat is not seen but is implied by the heat source. The pile of sugar in the pot has a mass of 100 grams. There is a solid, light brown mass at the bottom of the pot. It has a mass of 100 grams. The mass of the sugar is the same in melted form as it is in solid crystal form. There was not a chemical reaction. Sugar did not change composition. It only melted. Melting point is a physical property, and this is a physical change.
Steel Wool + Oxygen (Fire)
Egg + Heat
Water + Heat
Zinc + Hydrogen Chloride
Sodium Hydroxide + Copper Sulfate
HELPPPP PLEASEEEEEE
After Interaction How was mass conserved it is discussed below:
Steel Wool + Oxygen (Fire): chemical change
Egg + Heat: chemical change
Water + Heat: physical change.
Zinc + Hydrogen Chloride: chemical change
Sodium Hydroxide + Copper Sulfate: physical change
What is conservation of mass?According to the rule of conservation of mass, no atoms are lost or created during a chemical process. Instead, the atoms combine in various ways to generate products. This is why the number of atoms in each element in a balanced symbol equation is the same on both sides of the equation.
Steel Wool + Oxygen (Fire):The steel wool is a grayish color and has a rough surface. Oxygen is transparent It looks like a powder, and like if it was rusted steel wool but then broken apart and turned into a powder Well Iron oxide is 7 grams and steel wool combined is 7 grams so that the mass was conserved Yes, this is a chemical change because the steel wool rusted and rust is a chemical change, so iron oxide is cause because if a physical change.
Egg + Heat:The egg has a yellow yolk in the middle while there is some type of liquid at the border of the yolk, but it is clear, the heat is hot but transparent The egg turned into a delicious food called an omelet what was yolk staid as a liquid but got a tad harder, but the transparent border around it turned white It was conserved because the eggshell was 4 grams and the fried egg is 41 grams It is a chemical change because it results in the formation of new particles, and the chemical bonds break up and new ones are formed.
Water (H₂O) + Heat:The water is a clear liquid, while the heat is very hot but transparent The water turned into a type of oxygen -Water Vapor- If 5 g of water becomes a gas it becomes 5 g of water vapor. The mass of the liquid water is simply transferred into the mass of the newly formed water vapor. There was no chemical reaction because the water vapor can be turned back to water also it just changed from a liquid to a gas and did not change its composition. So, it is a physical change.
Zinc (Zn) + Hydrogen Chloride (HCl):Zinc: a white/silver metallic solid. Hydrogen chloride (dilute hydroelectric acid) a transparent, colorless liquid with a very low pH (acidic). Zinc "dissolved" in hydrogen chloride, while emitting a colorless gas. The liquid remains a colorless liquid, possibly still having a low pH from the unused acid. The colorless gas collected in a test tube gives a popping sound when ignited with a burning wooden splint, so it is not air embedded in the zinc, nor dissolved in hydroelectric acid. Well although the zinc chloride is 12 grams and not 15 the gas that was released was 3 grams and as we all know 3 + 12 is 15 so that the mass was conserved The production of a new substance (most probably hydrogen) from the reaction of the two reactants. When a few drops of the liquid product are evaporated on a watch glass, a white residue is left. When a few drops of the liquid hydroelectric acid are evaporated on a watch glass, there is no residue. This proves that a new product (hydrogen gas), (white powder, zinc chloride) is produced instead of zinc being physically dissolved in hydroelectric acid. So, it is a chemical change.
Sodium Hydroxide + Copper Sulfate-Sodium hydroxide is a turbid solution and copper sulfate is in form of bright blue crystals. When their solutions are mixed with each other, a pale blue precipitate of basic copper hydroxide & a solution of neutral salt sodium sulfate will be formed. The sodium hydroxide and the copper sulfate combined make a total of 67 grams and the product is split because the sodium sulfate is 47 grams and the copper hydroxide is 20 grams but all together it is still 67 grams so you could say that the mass was conserved. The proof of the reaction is the appearance of pale blue precipitates of basic copper hydroxide & a solution of neutral salt sodium sulfate. So, it is physical change.

1.Are Algae classified as plants or animals or both? Justify your answer
Algae are a non-monophyletic group, that is that it doesn't share a common ancestor, but share the characteristics of being able to photosynthetize, and the abscense of true vegetative tissues. They are more related to plants than animals, sharing the same type of nutrition (autotrophy) thanks to the acquisition of the chloroplast, which allows them to do photosynthesis. Actually, plants evolved from a group of Algae called Chlorophyta.
So, the correct classification of this organisms isn't neither as plants nor animals.

NaCl will have a boiling point between that of NaF and MgO because the covalent character of the bonds in
NaCl is intermediate between that of MgO and NaF.
NaCl will have a higher boiling point than MgO because the ions are spaced farther apart in NaCl.
NaCl will have a higher boiling point than MgO because the energy required to transfer electrons from the

Explanation:
Because the ions in NaCl are further distant from one another than those in MgO, NaCl will have a higher boiling point.
Why is the boiling point of nonane so high?NaCl has a greater boiling point than MgO because its ions are wider apart from one another.Due to its longer carbon chain than octane, nonane will have a higher boiling point. Since octane branches less than 2,2,3,3-tetramethylbutane, it has a bigger "surface area" and stronger van der Waals forces, which will cause it to boil at a higher temperature.London dispersion forces are stronger in liquid I2 because I2 molecules have more polarizable electron clouds than Br2 molecules do.Distillation. Distillation is a process of separation based on variations in the boiling points of compounds, as explained in analysis: Interference removal: Distillation.The fact that larger molecules of the same kind have greater boiling points than smaller ones suggests that dispersion forces rise with mass, number of electrons, number of atoms, or some combination of these.To learn more about MgO, NaCl will have a higher boiling point refer to:

Both the Precambrian and Phanerozoic eons had diverse life adapted to different environments.
The option that best distinguishes the Precambrian and Phanerozoic eons is "Life was rare and simple in the Precambrian and then underwent a sudden increase in diversity in the Phanerozoic." This is because the Precambrian eon, which lasted from about 4.6 billion years ago to about 541 million years ago, is characterized by the appearance and evolution of life, from simple prokaryotic cells to more complex eukaryotic cells. However, the diversity of life during this time was limited compared to the explosion of life that occurred during the Phanerozoic eon, which began about 541 million years ago and continues to the present day. During the Phanerozoic eon, there was a sudden increase in the diversity of life, with the evolution of many new species and the development of complex ecosystems. This increase in diversity was driven by a combination of factors, including the availability of new ecological niches, the evolution of new body plans, and the emergence of new types of organisms. Overall, the Precambrian eon was a time of gradual evolution and diversification of life, while the Phanerozoic eon was a time of rapid diversification and innovation.

Since the two individuals are heterozygous, the genotypes they will have for freckles will be Ff for each. The probability of having a child with freckles will be 75%.
Heterozygous refers to the presence of two different forms of the allele for a trait. These two different alleles are actually the contrasting forms of a gene. For example, the trait height can have two contrasting alleles one for tall and one for dwarf.
Genotype refers to the genetic make-up or constitution of an organism. This genetic constitution can be for the entire genome or for any particular trait. The genotype also provides insight about the allelic combinations.

How would you explain the key concepts for the CWA in less than two minutes?
Answer:
Explanation:
vPoint Source - a source of water discharged to surface water through a discrete point - generally through a pipe, ditch, or channel.
Nonpoint Source - Nonpoint sources, such as parking lots or athletic fields, discharge runoff water to groundwater or surface water; runoff does not come from a pipe, ditch, or channel. These sources may contain pollutants such as pesticides, motor oil, and soaps.
Navigable Waters of the United States For the purposes of the Clean Water Act, the term "navigable waters" includes:
all waters used in commerce, including groundwater;
all interstate waters including wetlands, mudflats, and sand-flats; and
all other waters such as lakes, rivers, streams, wetlands and sloughs.
EPA policy states, "The majority of facilities in the U.S. have the potential to discharge to navigable waters." The Supreme Court decision in (2006) requires the Army Corps of Engineers and the EPA to determine whether there is a "significant nexus" between a navigable waterway and an area a spill might affect. In June of 2007, EPA and the Army Corps of Engineers released provisional interpretive guidance regarding the "significant nexus” question. According to this guidance, the agencies will assert jurisdiction over traditional navigable waters, wetlands adjacent thereto, and relatively permanent tributaries thereof. The agencies will generally not assert jurisdiction over swales and ditches that lack routine water flow. Finally, the agencies will apply the "significant nexus" requirement and make a case-by-case, fact-specific analysis on impermanent tributaries and other wetlands.
Additional executive orders were issued 2015 in 2019. Under the 2019 proposal, traditional navigable waters, tributaries to those waters, certain ditches, certain lakes and ponds, impoundments of jurisdictional waters, and wetlands adjacent to jurisdictional waters would be federally regulated. It also details what are not "waters of the United States," such as features that only contain water during or in response to rainfall (e.g., ephemeral features); groundwater; many ditches, including most roadside or farm ditches; prior converted cropland; stormwater control features; and waste treatment systems.
Could the requirement for one or more NPDES Discharge Permit apply to my campus?
If your campus discharges pollutants directly to navigable waters of the United States through a point source, you must obtain an NPDES permit or redirect the flow of the waste.
Stormwater releases from certain activities require an NPDES permit. The most common activities on college campuses requiring NPDES permits for stormwater are construction activities disturbing more than 1 acre, hazardous waste storage areas operating under the Resource Conservation and Recovery Act permit system, steam-generating power plants, and airports. See Stormwater section below.
Regulations issued by local water authorities, or Publicly Owned Treatment Works (POTWs), not NPDES permits, govern discharges into sanitary sewer systems. See Sewer Use (POTW) section below for more information about requirements for using POTWs for commercial or industrial waste disposal.
What do I have to do related to NPDES Discharge Permits?
Determine where wastewater flows from buildings and processes on your campus. Any industrial or commercial operation (e.g., ice rink melt pits, floor drains, and vehicle wash stations) that discharge into a water of the United States may require an NPDES permit. If required, you must obtain such a permit from the appropriate regulatory agency, probably your state environmental agency.
French drains, dry wells, and septic system leach fields are different from point source discharges because they do not immediately affect surface water. Some state and federal environmental agencies manage these systems under the Underground Injection Control program, part of the Safe Drinking Water Act. See Safe Drinking Water Act for more information.
