O A. warmer tropical oceans
B. cooler tropical oceans
C. warmer landmasses

Answer:

4. False

5. False

Explanation:

Answer:

The first answer for 4) is B and the answer for 5) is B.

Answer:

B. The mutation results in a new, dominant allele

C. The mutation occurs in a gene that controls development and alters differentiation of a cell type during development.

D. The mutation occurs in a codon and alters the function of the final protein

Explanation:

All the above things will change the ultimate expression or phenotype by altering the proteins. Choices B, C, and D will all change the outer functioning.

Choice A only affects the rate of transcription, so it may go faster or slower, but the end product will be the same.

This part that doesn't look like it's one of the choices ("The mutation occurs in a portion of an intron not responsible for exon splicing.") would not affect phenotype, because introns are removed before the RNA is sent out.

Choice E says that the amino acid sequence is unchanged, meaning the protein final product will be the same and the expression will not change.

A pipette of range 1.0-10uL is the most appropriate for taking a volume of 9 uL. So the correct option is A

In the lab, micropipettes are used to transfer tiny amounts of liquid, typically less than 0.1 uL. In addition to other labs, they are most frequently employed in chemistry, biology, forensics, pharmaceutical, and drug development. There are various sizes of micropipettes commonly used in the laboratory.

Micropipettes vary in size and volume dispensed, and based on those two factors, they also need various pipette tips. Micropipettes aspirate liquid using a disposable pipette tip; take note that only the tip of the pipette comes into touch with the solution. For each sample, a fresh tip is used to avoid cross-contamination.

The quality of a pipette tip is the most important factor to consider. Whether one is searching for a filter, low retention, or gel loading tip, it should be made sure that the pipette tip will function as accurately and precisely as the micropipette. The purity of your pipette tips should be checked.

Therefore the correct option is A.

Answer:

just tryna get points lol

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.

Explanation:

Homeostasis is achieved thanks to the coordinated functioning of all the interconnected structures that function to maintain a constant physical or chemical parameter (homeostatic control system), if there is a defective receptor that would lead to a homeostatic Imbalance.

Occurs when a variable is out of balance and control centers cannot maintain homeostasis, disease and death can occur.

Therefore, we can conclude that the homeostatic control system receives signals from its receptors and sends corrective signals to glands, tissues, and organs to maintain homeostasis.

According to the information, we can infer that the Independent variable: Temperature (specifically, the range of temperature). On the other hand, Dependent variable: Distribution of pikas. Additionally, Control: Pikas within their tolerance range of temperature and Constants: Other environmental factors, habitat conditions, and population of pikas.

In this experiment, the independent variable is the temperature, specifically the range of temperature. The researcher will manipulate and observe how different temperature ranges affect the distribution of pikas.

The dependent variable is the distribution of pikas. It refers to the geographical or spatial range in which pikas are found. The researcher will measure and analyze how the distribution of pikas changes in response to different temperature ranges.

To ensure test validity, a control group of pikas within their tolerance range of temperature needs to be included. This group will experience temperatures within the range they can tolerate, providing a baseline for comparison. By comparing the distribution of pikas in different temperature ranges to the control group, the researcher can determine the impact of temperature on their distribution.

To maintain validity, other environmental factors such as altitude, precipitation, vegetation, and habitat conditions should be kept constant across the experimental groups. Additionally, the population of pikas being studied should be consistent, without any significant changes in population size or genetic composition throughout the experiment. These constants help isolate the effect of temperature on pika distribution and minimize confounding variables.

In the graph shown above, a letter which represents the activation energy (EA) of a catalyzed reaction is: A. Y; the activation energy (EA) is reduced in a catalyzed reaction.

An enzyme can be defined as a biological catalyst that typically speeds up (accelerates) the rate of a chemical reaction such as the break down of food by the digestive system, especially by lowering the activation energy of its chemical reactants.

Generally, an enzyme speeds up or catalyzes the rate of a chemical reaction by lowering its activation energy.

In Science, an activation energy can be defined as the minimum quantity of energy that must be provided for reacting chemical elements or molecules, in order to enable them undergo a chemical reaction.

This ultimately implies that, the rate of any chemical reaction would be faster when its activation energy is lowered, decreased, or reduced.  

Based on the graph shown in the image above, we can infer and logically deduce that Y is a letter which represents the activation energy (EA) of a catalyzed reaction because the activation energy (EA) is generally reduced in any catalyzed reaction.

Neurotransmitters are chemical messengers that are released from the neuron as the action potential reaches the end of the axon. The correct statement is the third statement.

Neurotransmitters are chemical messengers and they relay signals between the neurons. As the action potential reaches the end of the axon, the vesicles consisting of neurotransmitters fuse with the presynaptic membrane and neurotransmitters are released in the synapse.

These neurotransmitters then bind with the receptors at the postsynaptic neuron. The effect of the neurotransmitter depends on the kind of the receptor and the kind of the neurotransmitter involved. The resulting effect can be either the inhibition or excitation of the postsynaptic neuron.

The entry of neurotransmitters through K+ channels into neurons does not lead to the rising phase of the action potential. The rising phase of the action potential is triggered by the opening of voltage gated ion channels that cause an influx of sodium ions.

Neurotransmitters are not released from muscle cells to activate motor neurons in the presence of botulinum toxin; rather, it leads to the inhibition of neurotransmitter release from muscle cells causing muscle paralysis.

Neurotransmitters are chemical messengers released in response to the action potential which is generated by the movement of sodium and potassium ions across the axon membrane. They are released into the synapse when the action potential reaches the end of the axon. This  release is inhibited in presence of botulinum.

In conclusion, neurotransmitters are released from neurons when the action potential reaches the end of its axon.

If for some reason a cell does not receive oxygen it will die.

Brain cells are extremely sensitive to oxygen deprivation. Some brain cells actually begin to die less than 5 minutes after their oxygen supply disappears. As a result, brain hypoxia can quickly cause death or severe brain damage.

Hypoxia occurs when there is a lack of oxygen in the body. It consists of reducing the supply of oxygen to the tissues that make up our body. When there is a shortage in the blood, for example, it is called hypoxemia, a serious condition that can lead to the death of the patient. The lack of oxygen in the body can have numerous causes.

If cells are deprived of glucose and oxygen, cells will die through necrosis.
