Answer:

A. decrease in the Sun's energy

Global climate patterns are dynamic: They are continually changing in response to solar radiation, atmospheric greenhouse gas concentrations, and other climate forcing factors. Among the more predictable of these changes are cyclical changes in solar radiation reaching the poles.

Reference: Stevens, A. (2011) Factors Affecting Global Climate. Scitable

B. by producing more greenhouse gases

A reasonable hypothesis is that any average global temperature increases due to increased atmospheric concentrations of global greenhouse gases will lead to some increase in the rate and amount of melting of polar ice and glaciers.

Reference: Kundzewicz, Z. (2008) Hydrosphere - an overview. ScienceDirect Topics

D. A hurricane carries ocean water across the coast and damages houses of people.

These spheres are closely connected. For example, many birds (biosphere) fly through the air (atmosphere), while water (hydrosphere) often flows through the soil (lithosphere). In fact, the spheres are so closely connected that a change in one sphere often results in a change in one or more of the other spheres. Such changes that take place within an ecosystem are referred to as events

What characteristics make a species vulnerable to extinction?

Slav-nsk [51]

Answer:

Many rare and/or endemic species exhibit one or more of the following attributes which make them especially prone to extinction: (1) narrow (and single) geographical range, (2) only one or a few populations, (3) small population size and little genetic variability, (4) over-exploitation by people

What is the volume of air that my lungs hold

UkoKoshka [18]

Answer:

Tidal volume

Explanation:

Tidal volume is the amount of air taken into the lungs in a single breath. However, the lungs can hold a total of about 4-6 liters, which is close to ten times the tidal volume. This amount is known as the vital capacity.

Please explain when you have smaller population does evolution happen faster

denis-greek [22]

Answer:

Small populations tend to lose genetic diversity more quickly than large populations due to stochastic sampling error (i.e., genetic drift). This is because some versions of a gene can be lost due to random chance, and this is more likely to occur when populations are small.

Why is retinoblastoma more common in individuals who have inherited the RB deletion and have the genetic predisposition for reti

kvasek [131]

Answer:

Retinoblastoma is more common in people due to the mutation of RB gene in them.

Explanation:

Retinoblastoma is a disease that affects the eyes of an individual. It is more commonly eye cancer which occurs on the retina of the eye. Retinoblastoma mainly affects younger children.

When the RB gene is mutated or it is deleted already on any one of a homologous chromosomes, then only one hit rather that two which is needed to cause the development of retinoblastoma and hence the probability is of retinoblastoma to occur is higher in the individuals who have already inherited the RB deletion and also have a genetic predisposition for the retinoblastoma.

How is HIV is a modern-day driving force for human evolution?

juin [17]

Answer:

Testing positive for HIV means a high chance of death and a good chance of lower reproduction rates. But some people are immune to HIV, which makes them more evolutionarily fit, likely to live longer, likely to reproduce more, which would increase the frequency of the immune allele in the population. Over time, this increase in frequency of the gene that causes immunity could spread across the human race and cause it to evolve.
