Answer:

Allele frequency is how often an allele occurs in a gene pool

Explanation:

Allele frequency refers to how common an allele is in a population. It is determined by counting how many times the allele appears in the population then dividing by the total number of copies of the gene. The gene pool of a population consists of all the copies of all the genes in that population.

Explanation:

Based on the mutation rate of the molecular clock, it will take 22.5 million years for one full base pair mutation to occur.

A molecular clock is a biomolecule which is chosen to serve as a clock due to its periodical changes in a regular pattern.

Mutation in genes can serve as molecular clock.

The mutation in the gene of coding for the venom mutates at a rate of 0.76 base pairs every 17.1 million years.

It will take 17.1/0.76 = 22.5 million years for 1 base pair to mutate.

Therefore, it will take 22.5 million years for one full base pair mutation to occur.

Four (4) spermatids result from one spermatogonium. Details about spermatogenesis can be found below.

Spermatogenesis is the process by which sperm cells are produced from the testes of a male animal.

Spermatogenesis involves series of mitotic and meiotic divisions that finally result into the haploid sperm cells.

Spermatids are haploid cells produced by meiosis of a spermatocyte that develops into a spermatozoon.

The spermatogonium divides mitotically into primary spermatocyte which then develops into secondary spermatocyte via meiosis. Each secondary spermatocyte forms 4 spermatids.

because they were originally long period comets whose orbits were perturbed by the gravity of the giant planets and directed into the inner solarsystem

Halley's Comet is part of our solar system because it orbits around the Sun.

Halley's Comet is a periodic comet that follows a predictable orbit around the Sun and brings it close to the Earth once every 75-76 years. Halley's Comet originated from the Kuiper Belt, which is a region of the solar system containing icy objects.

When the comet approaches the Sun, the comet's ice and dust sublimate, which creates a bright coma that can be seen from Earth. The comet's nucleus is about 11 kilometers in diameter.

Halley's Comet is observed by humans for thousands of years. The regular return of comets allows scientists to study them in detail, thereby, helping us understand comets and the early solar system.

Therefore, Halley's Comet is part of our solar system because it orbits around the Sun like the other planets or objects in our solar system.

The class of drugs for human immune deficiency virus infection which reduces how well HIV genetic material can be converted into human genetic material is called The Nucleoside Reverse Transcriptase inhibitors (NRTIs)

HIV also called human immunodeficiency virus is an infection that always attack the body immune system but majorly the white blood cells which is called the CD4 cells. The human immunodeficiency virus destroys these CD4 cells thereby causing a persons immune system to be weak and unable to fight other infections, leading to ill health.

The NRTIs also known as the Nucleoside Reverse Transcriptase inhibitors prevent viral replication, binding and interaction with the CD4+

Answer:

At low temperatures, gas particles have less kinetic energy, and therefore move more slowly; at slower speeds, they are much more likely to interact (attracting or repelling one another) upon collision

If the gas molecules collide at very low temperatures then the collision will be slower as the intermolecular forces are stronger at the lower temperature and it is demanding situation to give high energy in order to break the bonds.

The fate of gas molecules is the formation of making gases compounds by making the elements bind together in order to form a new compound.

At the lower temperature, the average velocity of the molecules that are possessed by the molecules is decreased therefore the gas molecules will have lesser kinetic energy and they will move very slowly in order to form a new compound.

Gases do not exert much of force on each other but they do possess a collision with each other  and the collision molecules are elastic so as they are able to do collision.

The hypothalamus communicates directly with pituitary gland.

Hypothalamus is a small part lied f the brain that is between the inferior and anterior of thalamus. This gland is linked up with the pituitary gland by the stalk-like infundibulum. The pituitary gland comprises of an anterior and posterior lobe and each love produce different hormones in response to signals from the hypothalamus.

posterior lobe contains the ends of nerve cells that is from hypothalamus. The hypothalamus transmitt the hormones directly to the posterior lobe via these nerves, and then the pituitary gland releases them.

Heyy.

So i did the alternative activity for this assignment.

In task one I only did part F:

answer:

Weathering damage on Cleopatra's Needle, an Egyptian obelisk in Central Park, New York City, is compared to known weathering rates of granites in various regions. The detrimental influence of the city's environment in 83 years of exposure has been attributed by textbook authors to damage to this coarse-grained foliated granite. As evidenced by the original depth of inscription in New York, about 11/2 inches of maximum surface reduction had occurred. Granite reduction rates in humid regions were calculated to be as low as 0.0076 mm per year, and even lower in deserts. The majority of the damage to the obelisk was caused by rising moisture laden with sulfate salts in Egypt, according to the findings. The hydration pressure of these salts, combined with frost wedging, is responsible for the major damage to the monument, which happened during its first few years in New York.

Answer:

The genotypes of the two parents are AO and BO. Blood types A and B are dominant over blood type O,

Explanation:

An offspring inherits their genotype (genetic makeup) from their parents with each parent providing one allele for a given trait. An offspring need only inherit one dominant allele to have the phenotype (observable physical characteristic) of that trait and must inherit a recessive allele from each parent in order to have that phenotype. For example, brown hair is a dominant trait and only one parent must provide that allele for hair color in order for their offspring to have brown hair. In order for the recessive trait of blonde hair to be the phenotype of the offspring, each parent must provide the blonde hair allele.
