Arms of the chromosome are unproportioned, with extra or missing genetic material is the change to the chromosome causes Robertsonian translocation. Thus, the correct option is D.

Acrocentric chromosomes are affected by a Robertsonian translocation. The narrow region where both halves of an acrocentric chromosome unite lies at the end of the chromosome in an acrocentric chromosome.

Acrocentric chromosomes fuse together in a Robertsonian translocation. Two "long arms" of DNA are fused together in this process. Because the ends of their short arms have comparable repetitive DNA sequences that predispose them to fusion, only chromosomes 13, 14, 15, 21, and 22 are involved in this form of translocation.

The propagation of an action potential across the plasma membrane of a cell depends on the presence of propagating electrical impulses.

The nerve impulse (or action potential) is a rapid change in the electrical potential of the membranes of neurons. For brief moments (few milliseconds) the electrical charge inside the nerve cell becomes more positive than the outside.

With this information, we can conclude that the propagation of an action potential across the plasma membrane of a cell depends on the presence of propagating electrical impulses.

Answer:

The population size is small

Explanation:

Genetic drift is a mechanism of evolution in which allele frequencies of a population change over generations due to chance (sampling error). Genetic drift occurs in all populations of non-infinite size, but its effects are strongest in small populations.

Answer:

The population size is small.

Explanation:

Market dominance is influenced by elements such as market share, brand awareness, pricing power and entry barriers.

If a manufacturer has a fairly large market share, a solid brand reputation, and devoted consumers, they can be considered dominant. Economies of scale can also aid in dominance, by allowing for cheaper production costs and competitive pricing.

New competitors may be discouraged by entry barriers such as costly financing requirements or proprietary technology. Market dominance may change over time, due to changes in consumer preferences or technological advances. To establish a fair market and prevent a single producer from abusing its dominant position, competition and regulatory measures are important.

DNA telomerase adds a tail to the DNA strand at the end of replication. Thus, the correct option is C.

DNA replication may be defined as a biological process in which the genome's DNA is duplicated in cells. It is completed in three steps, i.e. initiation, elongation, and termination.

DNA telomerase is an essential enzyme in DNA replication that augments the ends by duplicating the RNA template and extending one end of the chromosome.

Therefore, the correct option for this question is C.

The option that best describes the impact of urbanization on carbon cycle is : ( B ) Decaying organic matter increases in landfills, which increases the amount of carbon dioxide in the atmosphere.

When organic matter decays, this leads to an increase in landfills and as the landfills increases there is also a  corresponding increase in the amount in the carbon dioxide which will be released into the atmosphere.Also  an increase in the population of an area does not result in the increase of carbon dioxide in the atmosphere.

Hence we can conclude that The option that best describes the impact of urbanization on carbon cycle is Decaying organic matter increases in landfills, which increases the amount of carbon dioxide in the atmosphere.

The liver regulates most chemical levels in the blood and excretes a product called bile. This helps carry away waste products from the liver. All the blood leaving the stomach and intestines passes through the liver.

Within a phase, a change in heat causes the temperature of the substance to change as the kinetic energy of the molecules changes. During a phase change, however, a change in heat causes a change in the potential energy of the molecules and the temperature will stay the same.

Potential energy may be defined as a form of accumulated energy that relies upon the comparative situation of diverse parts of a system.

The above passage determines the differentiation between the kinetic and potential energies with respect to temperature and phase change.

The allele frequency for the recessive allele is B. 0.10. Thus, option "B" is correct.

The Hardy-Weinburg equation is p + q = 1, or p^2 + 2pq + q^2 = 1, where p is dominant and q is recessive.

If 10 out of 100 rabbits have white fur, 10% of the rabbits have white fur. Therefore, 90% of the rabbits have brown fur, which can be substituted into the first equation to becoming 0.9 + 0.1 = 1. Now that we know what p and q equal, we can solve the rest of the equation.

0.9^2 = 0.81

0.9 * 0.1 * 2 = 0.18

0.1^2 = 0.01

Therefore, the allele frequency of the recessive allele is 0.1.

Answer:

When a cold front overtakes a warm front, it creates what's called an occluded front that forces warm air above a frontal boundary of cooler air masses.

Explanation:

The presence of a cold front means that cold air is advancing and pushing underneath warmer air. This is because the cold air is ‘heavier,’ or denser, than the warm air. Cold air is thus replacing warm air at the surface.
