Explanation:
A P3 X
Each phospholipid is made up of a phosphate group and two fatty acid chains. The correct option is B.
What are phospholipids?Phospholipids are lipids that have two types of edges. It has a hydrophobic tail and a hydrophilic head. The plasma or cell membrane, according to the fluid mosaic model, comprises substances like proteins and phospholipids.
A phosphate head and a fatty acid (lipid) tail make up the phospholipid layer, also known as the phospholipid layer, which is formed by the phospholipid.
Small molecules like oxygen gas can diffuse through the phospholipid layer, which facilitates the passage of small molecules but not larger ones. Biological membranes are formed by two lipid layers, proteins, and glucans.
Therefore, the correct option is B. A phosphate group and two fatty acid chains.

Consider a simplified metabolic model to describe nitrogen metabolism in the body. Nitrogen is ingested in the food (F), a fraction of which is actually absorbed (A), the remainder being lost in the feces (W). The absorbed nitrogen is taken up by the muscle to make protein. At small fraction of the stored muscle protein undergoes degradation and the liberated nitrogen (L) is released from the muscle. Of the liberated nitrogen, a fraction is recycled back to the muscle (R), while the rest is lost to excretion (E) in the urine
The given question is incomplete, the complete question is:
Consider a simplified metabolic model to describe nitrogen metabolism in the body. Nitrogen is ingested in the food (F), a fraction of which is actually absorbed (A), the remainder being lost in the feces (W). The absorbed nitrogen is taken up by the muscle to make protein. At small fraction of the stored muscle protein undergoes degradation and the liberated nitrogen (L) is released from the muscle. Of the liberated nitrogen, a fraction is recycled back to the muscle (R), while the rest is lost to excretion (E) in the urine. If the nitrogen ingested in food is 100 g/day, but only 80% of the food is actually absorbed, while the rest goes to waste, what is the amount of nitrogen lost by excretion? Assume steady-state. Of the nitrogen liberated from muscle, 90% is excreted, while the rest is recycled, what fraction of the nitrogen entering the muscle is from the absorbed food? (In other words, what is the ratio A/(A+R)). Again, assume steady-state
Answer:
The amount of nitrogen lost in the process is 20 grams in a day and the fraction of nitrogen entering the muscle is 0.909.
Explanation:
Based on the given question, the amount of nitrogen absorbed is 80 percent of 100 grams, that is,
100*(80/100) = 80 grams in a day.
The concentration of nitrogen lost in the process is,
Nitrogen ingested-nitrogen absorbed = 100-80 = 20 grams in a day.
Let us assume that all the ingested nitrogen is liberated from the muscle. Therefore, 80 grams of nitrogen is liberated. If 90 percent of the nitrogen liberated from the muscle get excreted, then the value of excreted nitrogen will be,
90% of 80 grams = 90/100*80 = 72 grams
Now the nitrogen recycled will be,
Liberated nitrogen - excreted nitrogen = 80-72 = 8 grams
From the absorbed food, the fraction of the nitrogen entering the muscle will be,
80/(80+8) = 80/88 = 0.909.

What explains the presence in living humans of DNA sections which are identical to DNA
found in Neanderthals who lived 40 000 years ago?
Answer:
It can be explained by hybridization among human and neanderthal ancestral populations.
Explanation:
Next-generation sequencing (NGS) technologies coupled with bioinformatics tools have enabled to confirm admixture between Neanderthals and humans. The technique to identify admixture events consists in discovering nucleotide regions from neanderthal genomes that could be inserted in human genomes, thereby the observed sequence homology must be statistically significant (e-value). This emergent research field is known as paleogenomics.

How can you determine the optimum pH of an enzyme?
You can determine the optimum pH of an enzyme by graphing its pH activity and studying the results.
Enzymes each perform differently in distinct environments. Some require lower pH to function, while others achieve maximum performance at higher pH levels.
This relationship between the productivity of the enzyme and the pH can be studied and graphed. Once done, we can expect this graph to look like a parabola, increasing steadily until maxed, then gradually decreasing back to zero at the other extreme. The vertice of this parabola will give us the optimum pH for the enzyme.

Answer:
They are "anti" condons or "stop" condons
Explanation:
A cell has two pairs of submetacentric chromosomes, which we will call chromosomes IA, IB, IIA, and IIB (chromosomes IA and I B are homologs, and chromosomes IIA and IIB are homologs). Allele M is located on the long arm of chromosome IA and allele m is located at the same position on chromosome IB. Allele P is located on the short arm of chromosome IA, and allele p is located at the same position on chromosome IB. Allele R is located on chromosome IIA and allele r is located at the same position on chromosome IIB.
A. Draw these chromosomes, identifying alleles M, m, P, p, R, and r as they would appear in metaphase I of meiosis. Assume there is no crossing over.
B. Taking into consideration the random separation of chromosomes in anaphase I, draw the possible types of gametes that might result from this cell’s undergoing meiosis. Assume that there is no crossing over.
Answer:
A) Allelic position in the chromosomes:
IA ----------M------------:-----------P----
IB ----------m------------:-----------p----
IIA -----------------R--------------------:---------------------
IIB -----------------r---------------------:---------------------
B) Types of gametes (assuming there is no crossing over):
MPR; MPr; mpR; mpr.
Explanation:
In submetacentric chromosomes, the centromere is located near to the middle of the chromosomes.
Since these two pairs of homologous chromosomes do not undergo crossover, the resulting gametes after meiosis may have four (4) allele combinations.
You have isolated a new mutation in the T4 bacteriophage rII A gene and you map its location within the gene by recombination frequency. You find that this new mutation fails to give wild type recombinants with several different adjacent mutations located in the same gene. What type of mutation is this new one you just isolated
Answer:
A lethal mutation, thereby the resulting phenotype is not observed .
Explanation:
Lethal mutations are the result of genomic changes that may be lethal in certain conditions. In genetic research, this type of mutation has shown to be very useful in analyzing gene function (i.e., genes whose protein products are key for the survival of the organism in question), and they are perfect gene markers. In bacteriophages, for example, temperature-sensitive mutants of phage T4 that can not grow at temperatures higher 42°C have been identified (Edgar & Lielausis 1964).

Why is axon covered in insulated sheath?
Answer: Myelin Sheath. The Myelin Sheath of a neuron consists of fat-containing cells that insulate the axon from electrical activity. This insulation acts to increase the rate of transmission of signals. A gap exists between each myelin sheath cell along the axon.
Explanation:. Myelin can greatly increase the speed of electrical impulses in neurons because it insulates the axon and assembles voltage-gated sodium channel clusters at discrete nodes along its length. Myelin damage causes several neurological diseases, such as multiple sclerosis.

Explanation:
In rabbits, brown coat (B) is dominant to white coat (b). A rabbit breeder wants to know the genotype of his best looking male brown rabbit using a test cross. He has brown females and white females available to conduct his breeding experiments.
Required:
a. What should be the coat color of the female he must use in this test cross?
b. If the test cross produces seven (7) brown rabbits and one (1) white rabbit, what is the genotype of the brown male rabbit?
Answer:
a. white
b. Bb
Explanation:
A test cross usually involve crossing an individual whose zygosity is unknown with a homozygous recessive version of individual of the same species.
Brown coat (B) is dominant over white coat (b). Hence, there is no way to physically distinguish between a BB rabbit and a Bb rabbit because both of them will be brown. A bb rabbit however will be white in appearance.
A test cross would therefore involve crossing the brown male rabbit with bb (white) rabbit.
Assuming that the genotype of the brown rabbit is BB, all the progeny will be brown as shown by the cross below.
BB x bb
Bb Bb Bb Bb
In order word, assuming the genotype is Bb, some of the offspring will appear brown while some will appear white.
Bb x bb
Bb Bb bb bb
Hence, the only way the test cross would produce white offspring is if the genotype of the brown rabbit is heterozygous, Bb.
