A graph here shows the average frequency of beak depth for a species of
birds in an area. There is a higher frequency of intermediate beak depths,
with some variation within the population for beak size. A homeowner
removes the native landscaping that contained trees and shrubs that
formed fruits and nuts. The homeowner plants new trees that produce only
larger sized nuts. No more smaller berries or intermediate fruit food

What is natural selection?
Natural selection is a mechanism of evolution that occurs when individuals with certain advantageous traits are more likely to survive and reproduce, passing those traits on to their offspring. This process leads to a gradual change in the genetic makeup of a population over time, as beneficial traits become more common and less advantageous traits become less common.
Natural selection occurs because resources in nature are limited, leading to competition for survival and reproduction. The individuals with traits that best suit them to their environment will have a higher chance of success, while those with less suitable traits are more likely to die or fail to reproduce. Natural selection is a key driver of evolution and is responsible for the diversity of life on Earth.

Difference between pure tone and speech audiometer
Answers
Answer:
Speech audiometry was performed on 15 children with secretory otitis media pre-and post-operatively and the findings compared with the pre-and post-operative pure tone audiograms. The results showed that in 30 per cent of cases pre-operatively the speech audiogram suggested a significantly worse hearing ability than that suggested by the pure tone audiogram (PTA). Where a PTA gives a borderline threshold disproportionate parental concern should be taken seriously as the hearing ability may well be worse than the PTA suggests.

Answers
The “great dying,” which saw 96% of all species extinct, was partially caused by an asteroid impact. So, the correct option is A.
What do you mean by Species?Species may be defined as a group of organisms that can reproduce with one another in nature and produce fertile offspring.
An asteroid impact threatens the whole biodiversity to a large extent. It leads to the destruction of almost all life forms living on the earth's surface.
Therefore, the “great dying,” which saw 96% of all species extinct, was partially caused by an asteroid impact.

It is the number of a particular species that an ecosystem can support. D.It is a process of chang during which species in a community are established or replaced.
Answers
Answer:
D. It is a process of change during which species in a community are established or replaced
Explanation:
Ecological succession is a process that occurs when a community is being established or replaced.
It shows the change in community over time, focusing on the types of plants and the maturity of plants that are in the community.
Primary and secondary succession are the two types of succession. Primary succession shows the process of change in the establishment of a community. Secondary succession shows the change when a community is being replaced.
So, the correct answer is D. It is a process of change during which species in a community are established or replaced

Explanation:
Sometimes an organ can be replaced by moving it from one part of the body to another. This can be done, for example, to replace damaged skin or joints. In these cases: antigens would be generated against the transplanted organ. rejection of the transplanted organ would still be expected. antibodies would be generated against the transplanted organ. rejection of the transplanted organ would not be expected. immunosuppressant drugs would be required to prevent transplant rejection.
Answers
Answer:
rejection of the transplanted organ would not be expected
Explanation:
Transplantation refers to 1-the movement of an organ/tissue/cells from one part of a person's body to another part, and 2-the movement of an organ/tissue/cells from one individual (donor) to another individual (recipient). An autograft is a type of transplant by which a patient receives his/her own tissue. For example, a skin autograft consists of a patch of skin that is removed from one area of the body and transplanted to another body region of the same individual. Skin autograft is a relatively common transplantation process used to repair wounds and restore skin function. In rats, the mechanism of skin autograft rejection has been reported as uncertain. Moreover, transplant rejection is a natural mechanism by which the immune system of a person does not recognize the transplant as its own, thereby attacking the transplanted organ/tissue. The autograft rejection reactions are relatively uncommon but they depend on the type of organ/tissue/cells to be transplanted.

gravity? O
(1 Point)
B) Precipitation of water that has condensed from clouds
D)Water seeping into the ground to enter an aquifer
C)Water flowing in a river toward the ocean
A) Evaporation of water from the ocean to form clouds
Answers
The correct answer is A. Evaporation of ocean water to form clouds.
Explanation
The water cycle is a series of physical-chemical phenomena in which water goes through three states (liquid, solid and gaseous). In this process, the water in a liquid state is evaporated becoming in a gaseous state, and rising towards the sky (against the force of gravity) forming clouds. Once in the clouds, the water condenses, going from a gaseous to a liquid state. After this process, the water precipitates by the action of gravity towards the earth where a process such as the filtration of water in the soil occurs, forming aquifers, the accumulation of water in the rivers that flow into the sea, the freezing of water on the snowy peaks of the mountains, among others. According to the previous explanation, the correct answer is A. Evaporation of ocean water to form clouds.
