Each gamete has half the number of chromosomes of the somatic cell. Hence, cats' gametes will have 19 chromosomes. Option C.
What are the type of cells in the organism?The types of cells in the organism are somatic and germ cells.
Both the somatic and germ cells go through mitosis producing two daughter cells with the same genetic dotation.
Somatic cells are any cell in the body except sperm and egg cells. They are diploid, meaning they contain two chromosome sets, each one inherited from each parent.
Germ cells are diploid reproductive cells. They suffer mitosis to form more sexual cells, and a few suffer meiosis to produce haploid gametes. Each germ cell produces 4 haploid gametes.

We used the enzyme, taq polymerase, which is derived from the thermus aquaticus bacterium, in our pcr procedure. Why is this enzyme important for efficiency in pcr?.
The enzyme Taq polymerase is required in the PCR process because it is the main enzyme that synthesizes the new DNA strands complementary to the template strand and without the activity of this enzyme the PCR will be useless and it cannot make the copy of the given strand in any way. Thus, this enzyme is very much necessary for the efficient working of the PCR.
Polymerase Chain Reaction is a very efficient technique that can able to detect and copy even a small amount of DNA by performing a set of reactions at different temperatures.
The PCR process begins with the denaturing of the template strand at 95°C, followed by annealing in which the appropriate primers bind to the single strands of DNA at 50-56°C, followed by extension at 72°C in which the thermostable Taq polymerase synthesizes the strand complementary to the template DNA.

The portion of the large intestine found between the transverse and sigmoid colon on the left side of the abdominal cavity is the colon.
Descending colon is found between the transverse and sigmoid colon on the left side of the abdominal cavity.
What are the components of large intestine?The cecum, colon, rectum, and anus are the components of the large intestine. Mesenteries are tissue folds that hold the colon and rectum in the belly.
Caecum: The colon and ileum (the last part of the small intestine) are connected by a pouch-like channel called the cecum.
Colon: The longest part of the large intestine is the colon. There are 4 sections in the colon-
Ascending colon: The colon begins with the ascending colon. It is located on the abdomen's right side. It continues upward until it reaches the hepatic flexure, a bend in the colon.Transverse colon: Following the ascending colon and hepatic flexure is the transverse colon. The upper portion of the abdomen is where it is located. The splenic flexure, a bend in the colon, marks its conclusion.Descending colon: The transverse colon and splenic flexure are followed by the descending colon. The abdomen's left side is where it is located.Sigmoid colon: The colon's final section, the sigmoid colon, joins to the rectum.Rectum: The lower portion of the large intestine that joins the sigmoid colon is known as the rectum. Its length is roughly 15 cm (6 in). It takes waste from the colon and keeps it there until the anus allows it to leave the body.

Suppose a reptile damages one of its kidneys, and the kidney is not able to function.
The levels of which material within the reptile’s body would most likely be affected?
carbon dioxide
nutrients
water
oxygen
REPTILES ARE METANEPHRIC KIDNEY
The correct option is (B) nutrient for the given question.
Reptiles are described as tetrapod vertebrate animals where they do perform excretion through small kidneys. Due to the lack of Loop of Henle in reptiles thus they aren't able to produce adequate urine that is excreted in concentrated form in solids.
A damaged kidney usually will have decreased perfusion resulting in activation of the RAAS Mechanism triggering an elevation of blood volume to an extent. Due to long-standing kidney diseases, there will be an accumulation of nutrients circulating within the bloodstream at higher levels such as (Creatinine, etc.) due to renal damage.

Why is the selective permeability of the plasma membrane essential for normal cell function?.
The selective permeability of the membrane is essential for the normal functioning of the cell because it maintains the internal order and functioning of the cell. Water, ions, glucose, and carbon dioxide may need to be imported or exported from the cell depending on its metabolic activity.
Along with this, the entry and exit of signaling molecules in the cell are also needed to be regulated. The presence of a selectively permeable membrane allows the cell to exercise control over the quantum, timing, and rate of movement of these molecules.
Plasma Membrane: It is a membrane that encloses all the constituents of the cell and separates them from the exterior environment. It is mainly made up of lipids and proteins.
Selective permeability of plasma membrane: The plasma membrane is selectively permeable in nature that is it allows entry and exit of only selected molecules in and out of the cell according to the requirements.

In negative control of transcription by the lac operon, how does the presence of an inducer affect transcription?.
In case, if the inducer of lac operon [allolactose] is present in the medium during negative control, then it can bind to the repressor and decrease the binding affinity of the repressor with the operator due to which the level of transcription increases.
Operon can be understood as an arrangement having multiple genes, all of which are being regulated under the same promoter. ex- Lac operon
Lac Operon is a set of three genes z, y & a which are regulated under the same promoter which regulates the amount of lactose production in the cell.
Under negative control, glucose is present and lactose is absent due to which no CAP [catabolite repressor protein] binding occurs, the repressor remains active and thus binds to the operator region of operon hindering the transcription process.
But, when the inducer will be present then it will manipulate the action of the repressor due to which the level of transcription increases.

Hiremagalur B, Sabban EL. Nicotine elicits changes in expression of adrenal catecholamine biosynthetic enzymes, neuropeptide Y and immediate early genes by injection but not continuous administration. Molecular brain research. 1995 Aug 1;32(1):109-15.
Nicotine, a key pharmacologically active component of tobacco smoke, is often regarded as one of the reasons responsible for cigarette smoking's negative repercussions. Nicotine stimulates the sympathoadrenal system, increasing catecholamine synthesis and release into the bloodstream.
In this work, we show that nicotine injections, both single and recurrent, enhance the expression of tyrosine hydroxylase (TH), a rate-limiting enzyme in the catecholamine biosynthesis pathway. In addition, these treatments influenced the expression of dopamine-hydroxylase (DBH) and neuropeptide Y (NPY) in rat adrenals.
Effects of Nicotine:Nicotine's influence on various transcription factors in the adrenal medulla was investigated. Injection nicotine treatment boosted CREB phosphorylation and activated c-Fos protein without altering members of the jun family. In contrast to the injection results, continuous infusion via osmotic pumps had no effect on any of these parameters.
These findings suggest that nicotine delivery modality influences the activation of many transcription factors and the production of TH, DBH, and NPY.
