Answers

Answer 1

When a piece of chromosome breaks off and reattaches at another site on the same or another chromosome, this is called chromosomal translocation.

In the field of science, chromosomal translocation can be described as a process in which a region of genes that is present on one chromosome have the ability to break and jump from to another chromosome and join to the other chromosomes.

These genes that take part in the process of chromosomal translocation are referred to as the jumping genes. It is due to the phenomenon of chromosomal translocation that same regions of genes in one chromosome can be found in another chromosome as well.

the release of insulin from the pancreatic beta cells can inhibit further release of insulin from the same cells. this is an example of which type of hormone action?

Answers

Insulin released from pancreatic beta cells may prevent more insulin release from the same cell. This is an illustration of how an autocrine hormone works.

Insulin is released when glucose and other carbohydrates that are digested by islets are consumed. The liver absorbs glucose & stores it as glycogen when the pancreatic B cells are activated too release insulin into to the circulation. Insulin then travels to body cells to help them absorb more glucose. Increased blood glucose levels cause insulin to be released. The – angiotensin – aldosterone system somatostatin is secreted by the delta cell, which makes up 4% of the islet cells. The islets of Langerhans' delta cells release somatostatin, which prevents the pancreas from secreting insulin. Several agonists, including prostaglandins, galanin, somatostatin, and norepinephrine

Evidence to why cetaceans closest living relative is the hippopotamus

Answers

The closest living relatives of the hippopotamus are cetaceans (whales, dolphins, porpoises, etc. ), from which they diverged about 55 million years ago.

Hippopotamus and whales may look different in so many ways, but they are actually each others' closest living relatives, sharing a common ancestor that lived about 55 million years ago. Despite their physical resemblance to pigs and other terrestrial even-toed ungulates, the closest living relatives of the hippopotamoids are cetaceans.

All cetaceans, including whales, dolphins, and porpoises, are descendants of land-living mammals. Cetaceans evolved from a group of mammals that include hoofed or “even-toed” ungulates such as cattle, deer, and sheep. The hippopotamus is the closest living ancestor to the cetacean group.

Whales and hippos share several adaptations to life in an aquatic environment, including oil-producing skin glands, the lack of hair, and the use of underwater vocalizations for communication.

Comparison of even-toed ungulate and cetaceans genetic material has shown that the closest living relatives of whales and hippopotamuses is the paraphyletic group Artiodactyl. Studies have suggested that the order Cetacea (whales, dolphins, and porpoises) might be more closely related to the order Artiodactyl.

FILL IN THE BLANK. if a sperm cell contains 8 chromosomes, it comes from an animal that has ______ chromosomes.

Answers

If a sperm cell contains 8 chromosomes, it comes from an animal that has 16 chromosomes.

This is because the animal's sperm cells and egg cells (also known as gametes) contain half the number of chromosomes as the animal's somatic cells (also known as diploid cells). During fertilization, the sperm cell and egg cell combine to form a zygote, which contains the full complement of chromosomes for the animal. For example, a human sperm cell contains 23 chromosomes, and a human egg cell contains 23 chromosomes, for a total of 46 chromosomes in the fertilized egg.

if the genotype aa is embryonic lethal and the genotype aa is fully viable but sterile, what genotype frequency would be found in adults in an equilibrium population for a heterozygous genotype?

Answers

Due to their sterility and lethality, AA and AA are unable to breed. Because all AA would perish, only heterozygotes would produce 2/3 Aa and 1/3 aa. The idea of random mating is not required.

A person having the genotype Aa can produce both A and a gametes. Given that this is a random process, the person will typically produce an equal quantity of each gamete. (For each gamete, the frequency is half.)

Homozygotes are people having the genotypes AA and aa (i.e., they have two copies of the same allele).

People who have the genotype Aa are heterozygotes (i.e., they have two different alleles at the A locus).

1- Which of the following organelles is less affected by the lipid solvents?
c) Lysosome.
d) Plastid
a) Mitochondrion.
b) Ribosome.

Answers

C) Lysosome

Lysosomes are organelles found in the cytoplasm of eukaryotic cells. They are small, spherical vesicles that contain a range of hydrolytic enzymes, which are enzymes that break down molecules by adding water. These enzymes help the cell to digest and recycle its own molecules, as well as to break down foreign substances that enter the cell.

One of the key characteristics of lysosomes is that they are relatively resistant to the effects of lipid solvents, such as alcohols and detergents. This is because the membrane of a lysosome is composed of a special type of lipid called sphingomyelin, which is more resistant to these solvents than other types of lipids.

In contrast, the other organelles listed (mitochondria, ribosomes, and plastids) are more susceptible to the effects of lipid solvents. The membranes of these organelles are composed of more common types of lipids, such as phospholipids, which are more easily disrupted by solvents. Therefore, lysosomes are less affected by lipid solvents than the other organelles listed.

Answers

Auricle, auditory canal, malleous, incus, stapes, oval window, cochlear duct, scala tympani, secondary tympanic membrane, and tympanic membrane

Why is the auditory canal necessary?

The external auditory meatus of the ear receives the sound waves and directs them there to be amplified. The flexible, oval membrane known as the eardrum, or tympanic membrane, is situated at the outer end of the ear canal.

What happens if the tympanic membrane is hurt?

When the eardrum ruptures, there is a hole or tear in the thin tissue separating the ear canal from the middle ear (tympanic membrane perforation) (eardrum). An eardrum rupture may lead to hearing loss. This could make the middle ear more prone to infections.

What is the main function of the cochlear duct?

The cochlea, a hollow spiral-shaped bone found in the inner ear, is crucial to hearing and participates in auditory transduction. The brain transforms sound waves into distinct sound frequencies using electrical impulses.

if a cell in g1 has 22 unduplicated chromosomes (11 pairs), then how many total chromatids will the cell have during the g2 phase of the cell cycle?

Answers

If a cell in g1 has 22 unduplicated chromosomes (11 pairs), then there are 12 chromosomes present in the G1 phase. DNA doubles in size during the S phase of the cell cycle. As a result, there are still 12 chromosomes towards the conclusion of the second growth phase or premitotic gap period, but there are 24 sister chromatids.

The number of chromosomes does not change even while the number of chromatids doubles. The number of chromatids will be 24 and the number of chromosomes in the G 2 phase will be the same as 12. As a result, choice A is the right response.

The second gap phase, also known as the end subscript phase, is a period of increased cell growth, production of proteins and organelles, and internal structure remodeling as the cell gets ready for mitosis.

A thin, stained slice of tissue mounted on a microscope is called a Histological Section.


Utmost histological sections are 2D slices, from a 3D piece of towel. Exactly what will be seen on the microscope slide depends on the aeroplane of the section; that is, the position of the microtome cut, in relation to the anatomical structures in the towel.

For vivisection samples there's no latitude for deciding the aeroplane of the section, as the direction of the needletract determines what towel is available and how it's acquainted. Pathologists anticipate to view sections in their stylish exposure as this also gives them the stylish occasion of relating abnormalities. numerous anatomical structures aren't readily visible in thin, 2D sections, simply because utmost of the structure isn't present.

which is more likely to result in a nonfunctional protein insertion of one base or insertion of 3 base

Answers

A frameshift mutation is more likely to cause a protein to become dysfunctional. A point mutation might preserve the original amino acid sequence and the resulting protein, acting as a quiet mutation.

A frameshift mutation changes the base sequence in codons by causing the insertion and deletion of nucleotide bases. This alters the AA (amino acid) sequence and the proteins that follow. A silent mutation, which is a component of a point mutation, preserves the AA sequence and the protein that follows.

A frameshift mutation is a genetic change brought on by an insertion or deletion that changes how the DNA sequence is read. A chain of numerous smaller molecules known as nucleotides makes up a DNA sequence. Codons are units of reading that consist of three nucleotides and are used to represent specific amino acids or stop signals in DNA (or RNA) nucleotide sequences. To create a chain of amino acids and a protein, the codon sequence is read sequentially from the nucleotide sequence during translation.

There are several patterns that have been observed in the rates of evolution in different lineages. One of the most notable patterns is the concept of molecular clock, which is the idea that certain molecular changes in DNA occur at a constant rate over time. This allows scientists to estimate the amount of time that has passed since two species diverged from a common ancestor by comparing the differences in their DNA. Other patterns that have been observed include the idea of punctuated equilibrium, which is the idea that evolution occurs in bursts of rapid change followed by long periods of stasis, and the Red Queen hypothesis, which suggests that species must constantly evolve in order to keep up with their constantly changing environments.

Events of coral bleaching that cause a considerable loss of coral can cause dramatic changes in fish communities. This may result in fewer catches for fishermen pursuing reef fish species, which may have an effect on the availability of food and related economic activity.

Corals will eject the algae (zooxanthellae) dwelling in their tissues if the water is too warm, which will turn the coral entirely white. The term for this is coral bleaching.

Therefore, Climate change is the main factor causing coral bleaching.

Enzymes are proteins that act as catalysts in biochemical reactions. A catalyst is a substance that increases the rate of a chemical reaction without itself being changed in the process.

Enzymes are molecules that increase the rate of a chemical reaction by lowering the activation energy of the reaction. Activation energy is the amount of energy that is required to initiate a chemical reaction.

Enzymes are classified as catalysts, inhibitors, accelerators, or depressants, depending on their function in the reaction. A catalyst is a substance that increases the rate of a reaction without itself being changed in the process. This is the most common type of enzyme, and they are responsible for the majority of biochemical reactions that occur in living organisms. Inhibitors are molecules that reduce the rate of a reaction by binding to the enzyme and slowing or stopping its activity.

Accelerators are molecules that increase the rate of a reaction by increasing the binding affinity of the enzyme for its substrate. Depressants are molecules that reduce the rate of a reaction by decreasing the binding affinity of the enzyme for its substrate.

Enzymes are important components of all biochemical reactions, as they are responsible for lowering the activation energy of the reaction and increasing the rate at which it occurs.

Without enzymes, many biochemical reactions would simply not occur in living organisms, as the activation energy required for them to occur would be too high. By adding enzymes to a chemical reaction, the activation energy is lowered and the reaction can occur more quickly and efficiently.
