Answer:

Through the process of crossing-over

Explanation:

During prophase 1 of meiosis, each chromosome carefully pairs with its homologous chromosome. Homologous chromosomes aline together to make the crossing-over possible, the stage where they interchange their parts.

Crossing-over occurs between two homologous chromosomes in the equatorial plane, making the daughter cells genetically different from the original one.

The point where two chromatids interchange their genetic information is the chiasma, where new genetic material or information is produced to be inherited by descendants. Chiasma allows the crossing-over between two homologous chromatids, one of each parent.

The Crossing-over frequency between two genes depends on the distance between them. A short distance between genes is a small target for crossing-over to occur, which means that only a few of them will happen, compared with the number of events between genes that are more separated from each other.

In the exposed example, the chiasma must be placed between A and B genes.

Before crossing-over

The symbol * represents the area where the chiasma places and crossing-over occurs.

a.

The individual should be diagnosed for hypertension or high blood pressure.

b.

It is recommended that the patient should take low sodium diet because when sodium or salt enters the blood stream it increases the amount of water or fluids in the blood stream that leads to rise in blood pressure. The blood pressure increases if we take high salt diet due to which arterioles constrict.

c.

Diuretics- Diuretics are the first recommended therapy in treating hypertension. Diuretics such as thizides , pottasium sparing agents. Thiazide acts on distal convoluted tubule that inhibits Na+ and Cl - symporter. Diutetic removes water from body as urine and loss of salt.

Beta blockers - These are antagonists. They block the beta receptors found on the target cell membrane. Beta blockers slows down blood pressure. Atenolol is the beta blocker used for hypertension.

Alpha1 blocker - alpha 1 receptors helps in smooth muscle contraction and vasoconstriction. Vasodilator increases blood flow in the body that are devoid of oxygen that helps to reduce blood pressure.

angiotensin converting enzyme inhibitor - blocks angiotensin converting enzyme that prevents converting angiotensin I to angiotensin II and increases bradykinin levels in the body. These inhibitors helps in lowering blood pressure.

Answer:

D. C4 plants

Explanation:

Photosynthesis is the process by which plants and other photoautotrophs synthesize carbohydrates and oxygen from carbon dioxide, water, and light energy in chloroplasts.

Photosynthesis occurs in two stages:

The light-dependent reactions and

The light-independent reactions, or Calvin Cycle.

Light-dependent reactions occur in the presence of sunlight. In these reactions, energy from sunlight is absorbed by chlorophyll and converted into stored chemical energy, in the form of NADPH and ATP. The light-dependent reactions take place in the thylakoid membranes in the grana within the chloroplast.

Light-independent reactions or Calvin cycle: In these reactions, the energized electrons from the light-dependent reactions provide the energy to form carbohydrates from carbon dioxide molecules. There are three phases to the light-independent reactions: carbon fixation, reduction reactions, and ribulose 1,5-bisphosphate (RuBP) regeneration.

C3 plants carry out both the light-dependent and the Calvin cycle within the choroplast organelles. They carry out the Calvin cycle by producing a three-carboncompound called 3-phosphoglyceric acid, hence the name C3.

C4 plants carry out photosynthesis in a two-stage process that first produced a four-carbon intermediate compound in the chloroplast of a thin-walled mesophyll cell. Once synthesized, the plant pumps the intermediate compound into a thick-walled bundle sheath cell, where it splits the compound into carbon dioxide and a three-carbon compound. The carbon dioxide then undergoes the Calvin cycle.

CAM (crassulacean acid metabolism) plants carry out photosynthesis by absorbing sunlight energy during the day, and then using the energy to fix carbon dioxide molecules during the night.

During cellular respiration, a cell generates ATP, which is subsequently utilized to facilitate the movement of a molecule across the cell membrane. The stored energy in the glucose is used to produce ATP that can be converted to mechanical energy when the molecule moves across the cell membrane. Thus, the correct answer is Option 1.

During cellular respiration, a cell breaks down glucose into ATP, which acts as the energy currency in the cell. This ATP is then used to power cellular activities, including the active transport of molecules across the cell.

When glucose enters cellular respiration, its stored energy is slowly released and taken up as ATP. This energy conversion is mediated by a series of chemical reactions that occur during the stages of cellular respiration, such as glycolysis, the citric acid cycle, the electron transport chain and the breakdown of glucose and ultimately produce ATP molecules.

Once ATP is produced, it can be used by specific proteins called transporters or pumps built into the cell. These transporters harness the energy stored in ATP and use it to move molecules aggressively through the cell, against their increased concentration This movement requires an energy input and is essential for cellular internalization in various processes such as nutrient uptake, waste removal and signal transduction.

Therefore, the correct answer is Option 1.

The correct answer is Option  a. The stored energy in the glucose is used to produce ATP that can be converted to mechanical energy when the molecule moves across the cell membrane.

During cellular respiration, glucose is broken down in a series of enzymatic reactions in the presence of oxygen. This process occurs in multiple stages: glycolysis, the Krebs cycle (also known as the citric acid cycle or tricarboxylic acid cycle), and the electron transport chain.

In glycolysis, glucose is converted into pyruvate, generating a small amount of ATP and NADH. Pyruvate then enters the mitochondria, where it is further metabolized in the Krebs cycle, resulting in the production of more ATP and electron carriers (NADH and FADH2). These electron carriers donate their electrons to the electron transport chain, located in the inner mitochondrial membrane.

The electron transport chain uses the energy from the electrons to pump protons across the membrane, creating an electrochemical gradient. This gradient is used by ATP synthase to produce ATP from ADP and inorganic phosphate through a process called oxidative phosphorylation.

Once ATP is generated, it can be utilized by the cell to perform various energy-requiring processes, such as active transport of molecules across the cell membrane. In this case, ATP can be hydrolyzed by an ATP-powered pump, such as a sodium-potassium pump, providing the necessary energy to move molecules against their concentration gradient.

Therefore, the energy in the original glucose molecule is ultimately converted into ATP, which can be utilized as a source of energy for the cell. When ATP is hydrolyzed, the stored energy is released and can be converted into mechanical energy to drive processes like molecule transport across the cell membrane.

Answer:

Explanation:

Alright, buckle up, since this isn't your average "the answer is C" explanation. Sorry beforehand for this upcoming essay. To make this easier, I'll give out the answers to start and then leave a "Why?" portion in case you want an in-depth explanation. I recommend getting the answers first since I can tell you're in a hurry, but if you get the chance look over a thing or two I said. Now:

To start, the 4 genotypes for the Dark Gray Rabbit are DD, Dd\(^{ch}\), Dd\(^h\), and Dd.

Why? Well, we know Dark Gray is dominant to all other alleles, so a Dark Gray allele with any other allele will produce a Dark Gray Rabbit.

The same concept above applies to the other rabbits:

The Chinchilla rabbit is d\(^{ch}\)d\(^{ch}\), d\(^{ch}\)d\(^h\), and d\(^{ch}\)d.

The Himalayan rabbit is d\(^h\)d\(^h\) and d\(^h\)d.

The Albino rabbit is dd.

Part 2:

Chinchilla Rabbit

Why? Because you have 2 Chinchilla alleles, and since they don't dominate and aren't dominated by any other allele, the rabbit will be a Chinchilla Rabbit.

Dark Gray Rabbit

Why? Same rule of dominance, and plus, it was one of the phenotypes listed in the first question.

For the table, look at the help image.

And finally, for the plan, the first set of rabbits with have a 50% chance of producing a dd\(^h\) rabbit, which is a Himalayan rabbit. Then, breeding two of these will ALWAYS give you a Himalayan rabbit.

Why? Because the only alleles are d and d\(^h\), and since d\(^h\) is always dominant of d, there will never be a case where that rabbit is albino (thus always Himalayan)
