This genus of rod-shaped, facultatively anaerobic, gram-negative bacteria belongs to the Fusobacteriaceae family, and its individual cells are frequently connected in a chain.

Follicular Phase (Days 6–14): The menstrual phase and the early follicular phase coincide. The ovaries produce a number of ovarian follicles, each of which contains an immature egg (oocyte), following menstruation. These follicles are stimulated to grow by follicle-stimulating hormone (FSH). The follicles generate more and more estrogen as they develop. The uterine endometrial lining thickens and grows as a result of increased estrogen levels. Usually, one dominant follicle takes center stage while the others degenerate. The negative feedback loop on FSH, which stops the growth of new follicles, is also influenced by the rising estrogen levels.

Stiff bristles called annelid setae are found on the body. For instance, during peristaltic motion, they aid earthworms in adhering to the surface and avoiding backsliding. It is challenging to remove a worm directly from the ground because of these hairs.
The chaetae are found on paired, unjointed lateral outgrowths called annelid parapodia.

Following ovulation, a transient endocrine structure called the corpus luteum develops in the ovary. Its primary job is to make progesterone, which is essential for the endometrium, the lining of the uterus, to remain healthy throughout the second half of the menstrual cycle and the first few months of pregnancy. Therefore, choice C is the right one.

The bacteria is given form by its cell wall, which has a hard coating. One essential structural element of bacterial cells is the cell wall. By providing the cell with form and shielding it from external forces, it acts as a protective barrier. Different bacterial species can differ greatly in the structure and makeup of their cell walls.

Option C is accurate since the permeability of sodium ions across the membrane only increases when sodium voltage-gated channels open, allowing the ions to enter the cell.

Regardless of the gender of the older children, the odds of a son being born are always 1:1 to those of a daughter. This is because there are only two possible outcomes when a sperm fertilizes an ovum: either a sperm with an X chromosome fertilizes an egg with an X chromosome to produce the XX genotype, which is for females, or a sperm with a Y chromosome fertilizes an egg with an X chromosome to produce the XY genotype, which is for males. The gender of any previous children the couple may have had has no bearing on this. 50% is therefore the right choice.

At the base of the thalamus is the hypothalamus. Because of its connection to the pituitary gland, it offers an anatomical link between the endocrine and neurological systems. The hypothalamus regulates body temperature. It is therefore referred to as the body’s “thermostat.” It uses a sophisticated thermostat system to maintain body temperature at about 37°C. Therefore, any localized damage to the hypothalamus will interfere with the body’s ability to regulate its temperature.

In the context of genetics, codominance describes a form of inheritance where two distinct expression patterns (alleles) of the same gene result in distinct traits in an individual.

Since an abductor muscle is any muscle that causes a limb to move away from the body’s midplane or away from a nearby part or limb, option D is the right choice.

Since a flexor muscle is any muscle that reduces the angle between the bones on two sides of a joint, such as when bending the elbow or knee, Option A is incorrect.

B. is incorrect because an extensor muscle is any muscle that straightens the elbow or knee to increase the angle between limb members.

C. is incorrect because a limb or other body part is moved toward the body’s midline or another part by the contraction of the adductor muscle.

Your pancreas produces the hormone glucagon to help control your blood glucose (sugar) levels. While insulin, another hormone, lowers blood sugar levels, glucagon raises them and keeps them from falling too low.

The thick and thin myofilaments that make up the myofibrils contribute to the muscle’s striated appearance. ‘Myosin’ makes up the thick filaments, while ‘actin’ makes up the thin filaments.

As a group of animals that lay eggs, monotremes serve as a link between reptiles and mammals. Examples include the spiny anteater and duckbill platypus.

The cecum, colon, rectum, and anal canal are the four sections that make up the large intestine. Food that has been partially broken down passes through the cecum and into the colon, where water, certain nutrients, and electrolytes are eliminated. After passing through the colon, the solid waste known as stool is stored in the rectum before exiting the body through the anal canal and anus. A tiny, tube-like organ connected to the first segment of the large intestine is called the appendix.
