X - Granulocytes and Y - Agranulocytes

White blood cells, commonly known as leukocytes, are in charge of keeping your body clean. White blood cells circulate in your circulation as part of your immune system and respond to damage or sickness.

White blood cells defend your body against infection. As your white blood cells travel through your circulation and tissues, they detect the presence of an infection and work as an army general, alerting other white blood cells to their position in order to assist defend your body against an unknown organism's onslaught.

When your white blood cell army arrives, it fights the intruder by creating antibody proteins that adhere to and kill the pathogen.

Granulocytes and agranulocytes are two types of WBCs.

Granulocytes

Granulocytes are white blood cells with tiny protein-containing granules. Granulocyte cells are classified into three types:

Basophils: These make up less than 1% of white blood cells in the body and are often found in higher quantities following an allergic reaction.

Eosinophils: These are responsible for reacting to parasitic infections. They also play a function in the body's overall immunological response as well as the inflammatory response.

Neutrophils make up the vast bulk of white blood cells in the body. They function as scavengers, encircling and killing bacteria and fungi that may be present in the body.

Agranulocytes

Lymphocytes

Among these white blood cells are the following:

B lymphocytes: These cells, also known as B-lymphocytes, create antibodies to aid the immune system's response to infection.

T cells, also known as T-lymphocytes, are white blood cells that aid in the recognition and removal of infection-causing cells.

Natural killer cells (NKCs): These cells are in charge of attacking and destroying viral and cancer cells.

Monocytes

Monocytes are white blood cells that account for around 2-8% of the body's total white blood cell population. These are present when the body defends itself against persistent infections.

They hunt down and kill infected cells.

She should be informed by the counsellor that since deafness is not inherited and both she and her husband have normal vision, there is absolutely no chance that her children will be either blind or deaf in one ear.

The X chromosome contains the genes that cause color blindness. Yet, a son's (a male offspring) X chromosome does not come from the father but rather from the mother. Hence, even though a father and his son both have color blindness, the son got it from his mother.

An X-linked recessive genetic disease called colorblindness exists. No, a colorblind mother cannot give birth to a normal son.

The expected habitat of a fish that possesses the ability to produce copious amounts of urine and the ability to move ions via active transport across the gills would be c. Fresh water.

Freshwater fish must produce a significant amount of urine to maintain their internal salt levels as the salt concentration in their external environment is lower than in their internal environment.

This excess urine production helps them excrete excess water and retain the necessary salts for survival. An important adaptation for freshwater fish is the ability to transport ions actively across their gills. This ability allows them to take up salts actively from the water and maintain their internal salt levels.

If freshwater fish were unable to transport ions actively across their gills, they would be unable to regulate their internal salt levels effectively and would be at risk of dying.

In summary, the ability to produce large amounts of urine and actively transport ions across their gills are essential adaptations for freshwater fish to regulate their internal salt levels effectively and survive in their environment.
Therefore, the expected habitat of a fish with these traits would be fresh water.

The Platyrrhimne originated in Africa is the correct answer

Platyrrhines are thought to have originated in Africa, from where they probably spread to South America in the middle or late Eocene. The oldest fossil record, described as Perupithecus, was recently discovered in western Peru (Santa Rosa) and is estimated to date back to the late Eocene. Evidence of an African origin is supported by the exceptional morphological similarity between Perupithecus and Talahpithecus of the late North African Eocene, which share nearly identical diagnostic characteristics such as cusps, ridges, and pelvises in the upper molars. These results support the hypothesis of a transatlantic spread event during the Eocene, likely by rafting on booming forest islands.

Explanation:

AAA (codes for the amino acid lysine, Lys) being mutated to AAG (which also codes for Lys) are some silent point of mutations.

One of the three forms of substitution mutations (also known as point mutations), along with nonsense and missense, is a silent mutation. A silent mutation specifically happens when a change in a gene's DNA sequence has no impact on the subsequent amino acid sequence of the protein it codes for. Since both of those codons translate to the same amino acid, Ser, or serine, there is no actual change in the protein produced by this gene if the DNA sequence changes from AGC to AGA, for instance. However, the matching RNA would change from UCG to UCU. Because it has no immediate impact, the mutation is said to be "silent." The quiet mutation is one of the various point mutation kinds, which are all displayed below.

The correct answer is option (C) "I and III."

Both statements I and III are correct regarding seed dormancy. Statement II is incorrect.

Statement I states that seed dormancy is a result of endogenous control, which is true. Endogenous factors within the seed, such as hormones and genetic mechanisms, regulate the dormancy period and prevent germination until certain conditions are met.

Statement II suggests that delayed germination is advantageous to plants. However, this statement is incorrect. Delayed germination is not universally advantageous to plants. While some seeds may benefit from delayed germination to ensure favorable environmental conditions for growth and survival, other seeds may have evolved strategies for immediate germination. The advantage of delayed germination depends on the specific ecological context and the species involved.

Statement III states that an impermeable and hard seed coat results in the dormancy of the seed, which is true. A hard and impermeable seed coat can prevent water uptake and gas exchange, thus inhibiting germination. This dormancy mechanism ensures that the seed remains dormant until conditions are favorable for germination, such as sufficient moisture, temperature, or light.

In conclusion, statements I and III are correct regarding seed dormancy. Seed dormancy is controlled by endogenous factors, and an impermeable and hard seed coat can contribute to the dormancy of the seed. However, statement II, suggesting that delayed germination is advantageous to plants, is incorrect.

A proton from water is added to the mechanism that produces the hydroxide ion. Water is an acid and the hydroxide ion is the conjugate base as a result. Ammonia accepts a proton to form an ammonium ion. The conjugate acid of the basic ammonia ion is called ammonium ion.

According to the Bronsted-Lowry acid-base theory, a conjugate acid is a chemical molecule that is created when an acid donates a proton (H+) to a base; in the other words, it is a base that has had a hydrogen ion added to it, as in the opposite reaction, the base loses a hydrogen ion.

A conjugate base, on the other hand, is what remains after an acid donates a proton during a chemical process. Therefore, a conjugate base is a species created by removing a proton from an acid since it can gain a hydrogen ion in the opposite reaction. The conjugate base of an acid may also be acidic since some acids have the capacity to release numerous protons.
