You have sampled a population in which you know that the percentage of the homozygous recessive genotype (aa) is 36%. Using that 36%, calculate the following:a. The frequency of the "aa" genotype. Answer: 36%, as given in the problem itself.b. The frequency of the "a" allele. Answer: The frequency of aa is 36%, which means that q2 = 0.36, by definition. If q2 = 0.36, then q = 0.6, again by definition. Since q equals the frequency of the a allele, then the frequency is 60%.c. The frequency of the "A" allele. Answer: Since q = 0.6, and p + q = 1, then p = 0.4; the frequency of A is by definition equal to p, so the answer is 40%.d. The frequencies of the genotypes "AA" and "Aa." Answer: The frequency of AA is equal to p2, and the frequency of Aa is equal to 2pq. So, using the information above, the frequency of AA is 16% (i.e. p2 is 0.4 x 0.4 = 0.16) and Aa is 48% (2pq = 2 x 0.4 x 0.6 = 0.48).e. The frequencies of the two possible phenotypes if "A" is completely dominant over "a." Answers: Because "A" is totally dominate over "a", the dominant phenotype will show if either the homozygous "AA" or heterozygous "Aa" genotypes occur. The recessive phenotype is controlled by the homozygous aa genotype. Therefore, the frequency of the dominant phenotype equals the sum of the frequencies of AA and Aa, and the recessive phenotype is simply the frequency of aa. Therefore, the dominant frequency is 64% and, in the first part of this question above, you have already shown that the recessive frequency is 36%.

The amniotic egg is a trait that separates amphibians from primates. The trait that separates rabbits and primates from crocodiles is eggs with shells. Rabbits and primates are mammals while crocodiles are reptiles.

The Amphibians are cold-blooded animals that spend part of their lives on land and some part in water. The primates on the other hand are warm-blooded animals and they produce milk(mammals). Species of monkeys, apes, and lemurs are some of the examples of primates.

The trait that is common in primates and rabbits is the presence of hair. The crocodiles on the other hand are different from them as they lay hard-shelled eggs which protect the inner portion of the egg and also allow gaseous exchange.

the correct answer might be neuro-toxin

You find the presence of cocaine in amoeba in a sewer. You classify this chemical as a neurotoxin.

Neurotoxins are artificial or naturally occurring compounds that harm, kill, or impair the central and/or peripheral nervous systems' ability to function.

Neurotoxins can harm glia, axons, and/or neurons, which can lead to demyelination or the loss of certain nuclei and/or axonal tracts.

When the normal functioning of the nervous system is altered by exposure to harmful substances (neurotoxicants), neurotoxicity develops.

As a result, neurons important cells that send and process information in the brain and other areas of the nervous system—may eventually get damaged or even killed.

In addition, neurotoxicity has been identified as a primary contributor to neurodegenerative illnesses like Alzheimer's disease (AD).

Thus, the answer is neurotoxin.

Answer

1. To change from Proline to Glycine

Step 1: Change the DNA of proline

Proline has the following four condons: CCG, CCC, CCU, and CCA.

And the Glycine codons are: GGT, GGG, GGA and GGC

So if the codons of Proline can be changed, C to G, we will have CCG, CCC, CCU, and CCA.

Which are the same as the codons of Glycine, when the tRNA translates, these will be amino acids of Glycine.

2. To change Tyrosine to Phenylalanine

The codons of Tyrosine are: UAU, UAC, UAA and UAG

Whereas the codons for Phenylalanine are: UUU, UUC, UUA and UUG

change the A to U in Tyrosine to get Phenylalanine

So the final Tyrosine codons will be: UUU, UUC, UUA and UUG.

The complementary mRNA sequence that is made during transcription from the given DNA sequence TACGGACCAG will be:

AUGCCUGGUCC

What is transcription ?

During transcription, the DNA sequence is used as a template to synthesize an mRNA molecule, where each nucleotide in the DNA sequence is complementary to a nucleotide in the mRNA sequence. In RNA, the nucleotide uracil (U) replaces thymine (T) found in DNA. So, the complementary RNA sequence to the given DNA sequence will have uracil in place of thymine. Thus, the mRNA sequence will have the complementary sequence to the DNA sequence as shown above.

What is DNA?

DNA stands for deoxyribonucleic acid. It is a long molecule made up of repeating units called nucleotides. Each nucleotide consists of a sugar molecule called deoxyribose, a phosphate group, and one of four nitrogenous bases: adenine (A), cytosine (C), guanine (G), or thymine (T).

The order of the nucleotides in the DNA sequence determines the genetic information of an organism. DNA is the genetic material that is passed down from parents to offspring and contains the instructions for the development, function, and reproduction of all living organisms.

The statement  that  are correct based on the gene expression are:

A)Inactive DNA prevents the gene expression at the earliest stage.

B) Removal of the mRNA before it is translated can regulate the gene

E) Genetic Information in Cells expression

Gene expression is the process by which the genetic information encoded in DNA is converted into functional products, such as proteins or RNA molecules, that carry out specific cellular functions.

The process of gene expression begins with the transcription of DNA into RNA, which is a process where a specific segment of DNA is copied into a complementary RNA molecule.

Therefore, the RNA molecule is then used as a template to produce proteins through a process called translation. The proteins produced through this process play a crucial role in the cell and are responsible for a wide range of functions, including structural support, catalyzing metabolic reactions, replicating DNA, responding to stimuli, and transporting molecules across cell membranes.

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.
