Each of the major hypotheses proposed to explain why sexual reproduction is more widespread than asexual reproduction ultimately bases its explanation on the adaptive benefit of:________.
a. forming large populations.
b. forming genetically distinct offspring.
c. reducing mutation rates.
d. forming relatively slow-growing populations.
e. forming gametes of different sizes.
Answer:
The correct answer is option b, that is, producing genetically distinct offspring.
Explanation:
It is found that sexual reproduction is more widespread in comparison to asexual reproduction primarily due to its adaptive benefit of producing offspring, which are genetically distinct. At the time of sexual reproduction, the genetic material of two individuals amalgamates to give rise to genetically-different offspring, which vary from their parents.
This tendency of reproducing sexually by the majority of eukaryotes is proof of its evolutionary success. The genetic diversity resulting due to sexual reproduction is considered to provide better chances of surviving in a modifying or unpredictable environment.

During the soybean experiment the nongerminating soybeans consumed around 0.02 mL/min of oxygen. What does this tell you about the cellular respiration of the nongerminating soybeans?A) There was no cellular respiration.B) A little cellular respiration was taking place but not enough for growth.C) There was enough cellular respiration occurring to allow for growth.D) Photosynthesis was occurring instead of cellular respiration.
Answer:
B) A little cellular respiration was taking place but not enough for growth.
Explanation:
Germination is a biological process that has a high energy demand, this requirement being fulfilled by cellular respiration. Cellular respiration enables the germinating seeds to convert chemical energy from oxygen (O2) molecules and nutrients into adenosine triphosphate (ATP), the energy currency of the cells. Cellular respiration increases as seeds emerge and begin to germinate. In this case, cellular respiration was not enough to fulfill the energy requirements of the germinating soybean seeds, which can be measured by the amount of O2 consumed during this process.

What movement of plates cause a earthquake
Answer:
The tectonic plates are always slowly moving, but they get stuck at their edges due to friction. When the stress on the edge overcomes the friction, there is an earthquake that releases energy in waves that travel through the earth's crust and cause the shaking that we feel.
Answer: The "Transform" and "Convergent" Tectonic plates

describing the process of photosynthesis) The process of photosynthesis
Photosynthesis is the process through which plants obtain their food from sunlight, also,many plants take light energy and convert into chemical energy with the help of chlorophyll pigment (green pigment)......
The process through which green plants and other organisms convert light energy into chemical energy is known as photosynthesis. Light energy is gathered and utilized during photosynthesis in green plants to transform water, carbon dioxide, and minerals into oxygen and energy-rich organic substances.
During this process, water is taken from the soil by the root hairs and transported to the leaves through the xylem vessels. Carbon dioxide enters through the stomata. The chlorophyll breaks water molecules into hydrogen and oxygen by absorbing the sun's light energy.
To produce glucose, carbon dioxide from the air and hydrogen from water molecules are combined. Additionally, as a waste material, oxygen is emitted into the atmosphere through the leaves.
While the rest is stored in the roots, leaves, and fruits for further use, glucose serves as a source of nourishment for plants, giving them the energy they need for growth and development.
Other essential biological elements of photosynthesis include pigments. They are the compounds that give color and absorb light at a certain spectrum while reflecting the light that was not absorbed. Chlorophyll and carotenoids, found in the membrane of chloroplasts, are the main components of all green plants. Its main purpose of it is to absorb light energy.

Genetic mutations are _____ harmful.
Genetic mutations may or may not be harmful, because if the mutation takes place in the exons region of the gene, then it is harmful, but if the mutation takes place in the introns, then it is not harmful.
What are the impacts of the genetic mutation?The genetic mutation occurs for a variety of reasons, including environmental factors, carcinogen products, or radiation, and the mutation's transmission depends on the site of the mutation. If the mutation happens in the somatic cells, then it is not likely to pass to the next generation, but if the genetic mutation takes place in the germ line cells, then it is more likely to pass to the offspring.
Hence, genetic mutations may or may not be harmful, because if the mutation takes place in the exons region of the gene, then it is harmful, but if the mutation takes place in the introns, then it is not.

Answer:
It's B
Explanation:
:)
A feature that may form as a result of erosion related to runoff are gullies.
Erosion refers to the washing away of top soil. One of the types of erosion is water erosion. This a situation whereby water washes away top soil. This water is called run off.
In areas that are prone to water erosion, one of the usual effects of surface runoff are gullies. A gully is a large depression in the ground that appeared as a result of erosion.
