The complementary strands will be CGU UC (GCA AG), AAU GC (TTA CG), CUA UG (GAT AC) and GCC UA (CGG AT).

In genetics, base complementarity can be defined as the match of nucleotide bases formed by hydrogen bonds.

In RNA, the Thymine nucleotide bases are replaced by Uracil nucleotide bases during complementarity.

Base complementary occurs because Adenine always pairs with Thymine, while Guanine pairs with Cytosine.

Mitosis is a longer and more complicated process than Binary fission because : ( B ) Mitosis has checkpoints that must be met to continue the cycle.

The process of mitosis is longer than binary fission due to the absence of spindle formation and sister chromatids in the process of binary fission.

Mitosis and binary fission are both means of asexual reproduction occurring in organisms. Mitosis occurs in eukaryotic organisms while Binary fission occurs in prokaryotic organisms.

Both process produces two identical daughter cells and they both replicate DNA  in each of the daughter cells produced. mitosis occur in eukaryotes ( organisms with cell nucleus ) therefore mitosis requires nucleus.

Hence we can conclude that Mitosis is a longer and more complicated process than Binary fission because : ( B ) Mitosis has checkpoints that must be met to continue the cycle.

The first one that points to the arrows under the sun is solar energy. The second one that points to the arrows below the could is evaporation. The third one that points at the cloud is condenstaion. The fourth one that points to the rain is precipitation.

Explanation:

Solar energy: Energy from the sun

Evaporation:  The process by which water changes from a liquid to a gas or vapor.

Condensation: Water which collects as droplets on a cold surface when humid air is in contact with it. (MAKES CLOUDS)

Precipitation: Rain, snow, sleet, or hail that falls to the ground.

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:

If the farmer crosses Bb x Bb, then the progeny will have BB, Bb and bb genotypes attributing to increased diersity of  corn kernel color in his crops.

The total complement of an organism's hereditary material is referred to as its genotype. The alleles or variants that an individual carries in a specific gene or genetic region are also referred to as their genotype. Genotype is another term for them.

There are three distinct categories of genotypes: heterozygous recessive (pp), heterozygous dominant (PP), and homozygous recessive (pp). Both the dominant homozygous genotype and the dominant heterozygous genotype exhibit the same characteristics.

Therefore, if the farmer crosses Bb with Bb, the offspring will have BB, Bb, and bb genotypes, which will contribute to an enhanced diversity of corn kernel color in the farmer's harvests.

The specific DNA sequence where RNA polymerase binds and initiates transcription is called the promoter region.

The chances of getting a red and white spotted flower if you cross a spotted flower with a white flower are - 25%.

This is an inheritance pattern in which both the alleles of a gene are expressed in an organism. In the camellia plant, alleles R and allele W will express themselves independently of each other.

Due to this, in heterozygous condition (RW) the phenotype appears as a hybrid that is presence of red and white patched flowers.

Crossing:  a spotted flower (RW) with a white flower (WW)

In terms of genetics, codominance is a sort of inheritance in which two distinct expressions (alleles) of the same gene result in distinct features in a person. That is, both qualities emerge rather than one trait predominating over the other, as in a plant or animal with multiple pigment colors.

One common characteristic of people that you can't really see just by looking at them, but that many people are aware of, is their blood type.

One A allele and one B allele are present in individuals with the blood type AB. Their blood type is AB because both alleles are expressed simultaneously.

The stages of bee development are egg, larva, pupa, and adult. Eggs hatch into larvae, which then transform into pupae. Finally, adult bees emerge and undergo further maturation.

The stages of bee development are:

1. Egg: The bee life cycle begins when the queen bee lays an egg in a honeycomb cell.

2. Larva: The egg hatches into a larva, which is a legless, grub-like creature. The larva is fed a special diet called royal jelly, which stimulates its growth.

3. Pupa: The larva undergoes metamorphosis and transforms into a pupa. Inside the sealed cell, the pupa undergoes various changes, developing into an adult bee.

4. Adult Bee: After completing the pupal stage, the fully developed adult bee emerges from the cell. The bee then undergoes further maturation, such as its exoskeleton hardening, wings expanding, and adult coloration appearing.

It's important to note that there are three castes of bees: queen, worker, and drone. The development process for each caste is similar, but the diet and size of the cells they are raised in differ, leading to their distinct roles within the colony.

In the signaling pathway shown, inositol triphosphate (IP3) acts as a second messenger. Influx of Ca2+ increases and leads to activation of other signaling pathways.

Inositol trisphosphate or inositol 1,4,5-trisphosphate abbreviated InsP3 or Ins3P or IP3 is an inositol phosphate signaling molecule. It is made by hydrolysis of phosphatidylinositol 4,5-bisphosphate (PIP2), a phospholipid that is located in the plasma membrane, by phospholipase C (PLC). Together with diacylglycerol (DAG), IP3 is a second messenger molecule used in signal transduction in biological cells.

While DAG stays inside the membrane, IP3 is soluble and diffuses through the cell, where it binds to its receptor, which is a calcium channel located in the endoplasmic reticulum. When IP3 binds its receptor, calcium is released into the cytosol, thereby activating various calcium regulated intracellular signals.

The advancements gained in South Carolina during Reconstruction were hampered by the emergence of hate groups like the Ku Klux Klan.

The development of hate groups like the Ku Klux Klan in South Carolina contributed significantly to Reconstruction's defeat. Black Americans were prevented from exercising their newly acquired political and social rights, such as voting and running for office, by these groups via the use of violence and intimidation. They also aimed to reinstate the previous social structure and uphold white supremacy. The ineffectiveness of the federal government in enforcing Reconstruction laws and safeguarding Black Americans from violent retaliation gave these groups more power and ultimately led to the breakdown of Reconstruction in South Carolina and other Southern states.
