The statement which is true about the two processes is that the products of cellular respiration are also the reactants of photosynthesis.
What is photosynthesis?
It is defined as a process by which plants and other photosynthetic organisms convert the light energy in to chemical energy through the process of cellular respiration.
Some of the energy which is converted is stored in molecules of carbohydrates like sugar and starches which are made up of from carbon dioxide and water . Photosynthetic organisms which can perform photosynthesis are algae and cyanobacteria.
The process begins with proteins absorbing light energy which are called reaction centers and contain a green pigment which is called chlorophyll . In plants ,these pigments are present inside organelles called chloroplasts while in bacteria they are present in plasma membrane.

what kinds of substitutions or insertions or deletions can occur? are there other types of mutations at larger scale?
Types of Substitutions: Transitions (substitute purine with purine)
Transversions (substitute pu w/ py)
Substitution mutations may have positive, negative, or no effects. Silent, missense, and nonsense mutations are three types of point mutations that they specifically induce. A silent mutation is one in which the protein's functionality is unaffected. The incorrect protein is coded for by a missense mutation.
An insertion in genetics is the addition of one or more base pair nucleotides to the DNA sequence. Because the DNA polymerase frequently slips in microsatellite regions, this frequently occurs.
Types of Insertions:
Frameshift mutations (insertion or deletion that alters the reading frame of the gene)
In-frame insertions and deletions ( deletion or insertion of a multiple of 3 nucleotides which do not Alter the reading frame)

Option 2 is the correct one , Antidiuretic hormone (ADH), which is produced in the hypothalamus and transported to and released from the posterior pituitary gland, is a polypeptide hormone. ADH's main function is to control how much water is expelled by the kidneys.
ADH, sometimes referred to as vasopressin, enables the kidney tubules to directly reabsorb water, which concentrates salts and wastes in the urine that hypothalamus will eventually be expelled. Either through controlling blood volume or the amount of water in the circulation, the hypothalamus regulates the processes of ADH production. A rise in osmolarity exceeding 300 mOsm/L due to dehydration or physiological stress can increase ADH production and water retention, which in turn elevates blood pressure.

When CRP binds to cAMP, a conformational shift occurs that causes CRP to bind to particular locations on DNA promoters. This interacts with RNA polymerase to activate transcription. CRP activity increases in response to a drop in glucose and a rise in cAMP. When glucose acts as a carbon source, cAMP levels are low. This results from the adenylate cyclase enzyme being inhibited (cAMP producing enzyme). Therefore, a drop in glucose will result in an increase in cAPM.

population of beetles, what traits are positively selected for?
Answer:
beetle population:
beetle color is controlled by many genes and varies in a spectrum from light to dark green.
Stabilizing selection. In stabilizing selection, intermediate phenotypes are more fit than extreme ones. For example, medium-green beetles might be the best camouflaged, and thus survive best, on a forest floor covered by medium-green plants. Stabilizing selection tends to narrow the curve.Directional selection. One extreme phenotype is more fit than all the other phenotypes. For example, if the beetle population moves into a new environment with dark soil and vegetation, the dark green beetles might be better hidden and survive better than medium or light beetles. Directional selection shifts the curve towards the favorable phenotype.Disruptive selection. Both extreme phenotypes are more fit than those in the middle. For example, if the beetles move into a new environment with patches of light-green moss and dark-green shrubs, both light and dark beetles might be better hidden (and survive better) than medium-green beetles.

Your tongue is covered in bumps called papillae. Papillae have taste receptors that are bundled together (taste buds). Taste buds have microscopic hairs called microvilli which send nerve impulses to the brain. However, your nose plays a role too! While you’re chewing, the food releases chemicals that travel up your nose and trigger olfactory receptors which also send nerve impulses to the brain to help you interpret the true flavor of what you’re eating. With this information, explain why a cold or allergies can diminish the flavor of your food.
During eating, the tongue and nose receptors collaborate to send signals to the brain that can provide an idea of the flavor. When one has a cold, the nose does not work well enough to detect smell of the food.
What is the role of receptors in the body?Many receptors on various cell types function differently, such as the tongue receptor, which sends food taste information to the brain. The nose receptors send the food smell to the olfactory region of the brain, but when a person becomes allergic or cold, the nose receptors stop working properly, and the smell does not reach the brain.

Maternal iron deficiency anemia during pregnancy results from a)insufficient iron intake for the increased requirements during pregnancy. b)fetal demand for iron in third trimester to store in the liver.
Because their iron stores must serve both their own increasing blood volume and as a source of hemoglobin for the developing child, many pregnant women develop iron deficiency anemia without iron supplements. Anemia in pregnancy is most frequently caused by an iron shortage. Anemia due to a lack of folate. The vitamin folate is naturally present in some foods, such as green leafy vegetables.

1. Potential phenotypes and genotypes
Solid HH (homozygous dominant)Solid Hh (heterozygous), and green spots are homozygous recessive (hh).2. The frequency of grasshoppers with no spots is [tex]\frac{445}{487}[/tex] , equal [tex]0.9138[/tex] (2 decimal places= 0.91)
3. The frequency of green-spotted grasshopper phenotypes is [tex]\frac{42}{487}[/tex], or [tex]0.08624[/tex] (0.09 = 2 decimal places)
4. The frequency of the recessive allele= The[tex]\sqrt{ genotypic frequency of homozygous recessives}[/tex] = [tex]\sqrt{0.08624}[/tex] = 0.29
Hardy Weinberg. Equation: [tex]p^{2} + 2pq+q^{2} =1 and p+q=1[/tex], and
p= frequency of the dominant allele
q = Recessive allele frequency
[tex]p^{2}[/tex] = homozygous dominant genotypic frequency
2pq = genotypic frequency of heterozygotes
[tex]q^{2}[/tex] = homozygous recessive genotypic frequency
The answer to question C's calculation [tex]q^{2}[/tex] is 0.08624, or the homozygous recessive frequency of grasshoppers with green spots.
As a result, q, the frequency of the recessive allele = [tex]\sqrt{q}^{2}[/tex] = √0.08624 = 0.29 (rounded to 2 decimal places)
5.. Dominant allele frequency is 0.71.
P + q = 1 according to the Hardy-Weinberg equation.
The ratio of the recessive and dominant allele frequencies must be 1.
We estimated that the recessive allele's frequency was 0.29.
As a result, [tex]1-0.29 = 0.71[/tex] is the frequency of the dominant allele (or q).
6. Because there is only ONE GENOTYPE (hh) of green spotted grasshoppers, the genotypic and phenotypic frequencies of these insects are identical. Remember that this is equivalent to the q2 value that we calculated the frequency of the recessive allele for in question D.
