Phosphorus is a critical constituent of cellular fluids because of its role: a.as a sodium ion transporter in body cells b.in the synthesis of amino acids c.in the synthesis of phospholipids to transport fats through the blood d.in binding with calcium in the muscle tissues e.as a buffer in maintaining the optimum body pH
Answer:
e is correct
Explanation :
Phosphorus is critical because this element is required for enzymatic activities that take place during glycolysis, in the metabolism of glutamine to form ammonia (ammoniagenesis) and also in oxidative phosphorylation, where the cells produce energy from the generation of ATP from ADP.
In serum (blood plasma), the inorganic phosphate is combined with oxygen (O2) to form diverse types of phosphates (PO4) molecules that play key functions in muscle activity, nervous system development, and bone growth.
Serum phosphate is a critical buffer that maintains the acid‐base balance in the urine. The serum phosphate level in an adult must be in the range of 2.5 to 4.5 mg/dl, being higher levels indicative of hyperphosphatemia. This inorganic phosphate has important functions during the ATP synthesis, cyclic AMP, post-translational modification (i.e., protein phosphorylation), and also as an intracellular buffer.

(a) Describe the possible genotypes of the heart cells of an individual if meiosis in this
individual results in two sperm cells carrying the f allele and two sperm cells carrying the
F allele.
Answer:
The possible genotype is Ff
Explanation:
The possible genotype of the heart cells of such individual would be Ff.
Meiosis usually results in the formation of daughter cells with haploid number of chromosomes from parent cells with diploid number of chromosomes. The chromosomes in the parent cells are usually halved in the daughter cells.
The cells of the heart will have diploid number of chromosomes because they are vegetative cells while the sperm cells will usually have haploid number of chromosomes because they are sex cells.
Consequently, the heart cells of an individual will contain twice the chromosome number present in the sperm cells of such individual.
Hence, if meiosis results in the formation of sperm cells with F and f genotypes in an individual, it simply means that any diploid cell in that individual will have the Ff genotype.
The possible genotype is Ff
The following information should be considered:
Meiosis normally arise when the daughter cells are created along with haploid number of chromosomes from parent cells with diploid number of chromosomes. The chromosomes in the parent cells are normally halved in the daughter cells. The heart cells should have diploid number of chromosomes since they are vegetative cells while on the other hand the sperm cells will normally have haploid number of chromosomes. Due to this, the heart cells of an individual will comprise of twice the chromosome number that are present in the sperm cells of such individual.

4. Bowen ailment is a skin illness that happens because of development of anomalous cells in the epidermis layer of the skin. Since the irregular cells keep themselves to the epidermis just and don't spread away from it, so it's anything but a sort of cancer. But there are odds of disease being caused later. Red expanding patches are seen on the skin which on occasion bleed. They are caused because of high paces of sun introduction, by Human papillomavirus, or because of immunosupression. Treatment incorporates applying creams, for example, 5-FU to murder strange cells, cryotherapy, laser treatment and radiotherapy too.

Explanation:
Based on the objective you should feel comfortable calculating expected genotype frequencies when given observed allele frequencies. You should also be able to compare expected genotype frequencies from HWE to observed frequencies and determine if evolution is occurring. Here's a sample problem. You can do this without a calculator! Let's take the noob gene, a gene with two known alleles that determines feather color in the eastern lark. The two alleles, let's call them delta and gamma, can be sequenced. In fact, looking at a population in southern GA, you discover that 60% of the alleles in the population are the delta allele. So question 1, what is the percentage of the gamma allele in the population
Answer:
40% is the percentage of the gamma allele in the population.
Explanation:
Available data:
Two alleles, delta and gamma60% of the alleles in the southern GA population are the delta alleleWhat is the percentage of the gamma allele in the population?
According to Hardy-Weinberg, the allelic frequencies in a locus are represented as p and q, referring to the allelic dominant or recessive forms. The genotypic frequencies after one generation are p² (Homozygous dominant), 2pq (Heterozygous), q² (Homozygous recessive). Populations in H-W equilibrium will get the same allelic frequencies generation after generation. The sum of these allelic frequencies equals 1, this is p + q = 1.
In the same way, the sum of genotypic frequencies equals 1, this is
p² + 2pq + q² = 1
Being
p the dominant allelic frequency, q the recessive allelic frequency, p² the homozygous dominant genotypic frequency q² the homozygous recessive genotypic frequency 2pq the heterozygous genotypic frequencyIf the percentage of delta allele in a population is 60%, this means that its frequency is 0.6. By clearing the equation p + q = 1, we can calculate the gamma allele frequency. This is:
p + q = 1
0.6 + q = 1
q = 1 - 0.6
q = 0.4
Then the percentage of gamma allele in the population is 40%.
We can also think about it like this:
If the sum of the allelic frequencies equals 1, then 1 is 100% of the allelic frequencies. And if the percentage of delta allele in a population is 60%, then 40% is the percentage of gamma allele.
Explain the plasma membrane in easy way.
Answer:
The cell membrane (also known as the plasma membrane (PM) or cytoplasmic membrane, and historically referred to as the plasmalemma) is a biological membrane that separates the interior of all cells from the outside environment (the extracellular space) which protects the cell from its environment.[1][2] The cell membrane consists of a lipid bilayer, including cholesterols (a lipid component) that sit between phospholipids to maintain their fluidity at various temperatures. The membrane also contains membrane proteins, including integral proteins that go across the membrane serving as membrane transporters, and peripheral proteins that loosely attach to the outer (peripheral) side of the cell membrane, acting as enzymes shaping the cell.[3] The cell membrane controls the movement of substances in and out of cells and organelles. In this way, it is selectively permeable to ions and organic molecules.[4] In addition, cell membranes are involved in a variety of cellular processes such as cell adhesion, ion conductivity and cell signalling and serve as the attachment surface for several extracellular structures, including the cell wall, the carbohydrate layer called the glycocalyx, and the intracellular network of protein fibers called the cytoskeleton. In the field of synthetic biology, cell membranes can be artificially reassembled.[

A receptor is a structure that detects stimuli. The stigma (eyespot) of Euglenoids detects ____, assisting with phototaxis. A. light intensity and direction B. vibrations C. chemicals D. sound frequency and direction E. temperature change
Answer:
The correct answer is option A, that is, light intensity and direction.
Explanation:
A photoreceptive organelle witnessed in the motile or flagellated cells of unicellular photosynthetic species like euglenoids and green algae is known as the stigma or the eyespot apparatus. It permits the cells of the organism to detect the intensity and direction of the light and react towards it.
This assists the organisms to either swim away from the light known as negative phototaxis, or to swim towards it known as positive phototaxis. The eyespots are the basic and the most typical eyes witnessed in nature. The eyespots comprise bright areas or orange and red granules of pigment and photoreceptors.
In this lecture you learned that due to ___________descent, organisms share many of the same genes and proteins. However, distantly related organisms have _______ DNA differences than closely related organisms.
Answer:

more
Explanation:
In this lecture you learned that due to evolutionary descent, organisms share many of the same genes and proteins. However, distantly related organisms have more DNA differences than closely related organisms.
Organic evolution general refers to the descents, with modification, of organisms from common ancestors. Hence, organisms that share the same ancestors share several similar genes and proteins due to their common lineage. The closer the organisms, the more similar their genes and proteins, and the distant the organisms, the more dissimilar their genes.

The diffusion spot diameter with one crystal at 15 min ( mm) is 59 . The rate of diffusion with one crystal So how would I convert this 59 to ( mm/h)?
Answer:
This is straight forward.If there are 60 minutes in one hour, then to convert minutes to hours as requested, simply divide the number of minutes given by 60.Thus if you divided the 59 by 60 it gives you what?round the answer to whole number.
When there is a moment of any solute present in the solution from high concentration to low concentration area is called diffusion.
It will take 0.25 hours to diffuse one crystal.
This can be calculated by:
Given,
Time for one crystal diffusion = 15 minDiameter for one crystal diffusion = 59 mmIn 1 hour there are 60 minutes.
60 minutes = 1 hour.
Then 15 minutes = ? hours
