8. What can scientists assume about species with similar embryos?

9. What is biogeography and why is it important for proving the theory of evolution?

10. Describe one area where microevolution can be observed today

Answers

Answer 1
Answers :
3. Fossils give us information about how animals and plants lived in the past. Some animals and plant are only known to us as fossils. By studying the fossil record we can tell how long life has existed on Earth, and how different plants and animals are related to each other.

4. Yes. As the theory states that organisms have gradually changed from one from to another form transitional fossils should be found that show evidence of the transitional forms of the organism. In using the fossil record to support the Darwinian theory of evolution finding these transitional fossils is important.

5. Comparative anatomy is the study of the similarities and differences in the structures of different species. Similar body parts may be homologies or analogies. Both provide evidence for evolution.The structures are similar because they evolved to do the same job, not because they were inherited from a common ancestor.

6. Homologous structures share a similar embryonic origin; analogous organs have a similar function. For example, the bones in the front flipper of a whale are homologous to the bones in the human arm. These structures are not analogous. The wings of a butterfly and the wings of a bird are analogous but not homologous.

7. Structures that have lost their use through evolution are called vestigial structures. They provide evidence for evolution because they suggest that an organism changed from using the structure to not using the structure, or using it for a different purpose.

8. Evidence of an evolutionary common ancestor is seen in the similarity of embryos in markedly different species. Darwin used the science of embryology to support his conclusions. Embryos and the development of embryos of various species within a class are similar even if their adult forms look nothing alike.

9. Biogeography, the study of the geographical distribution of organisms, provides information about how and when species may have evolved. Fossils provide evidence of long-term evolutionary changes, documenting the past existence of species that are now extinct.

10. The process by which new species are produced from earlier species (speciation). It also involves processes leading to the extinction of species. ... Examples of macroevolution include: the origin of eukaryotic life forms; the origin of humans; the origin of eukaryotic cells; and extinction of the dinosaurs.

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.

Auxins cause cells to grow ___. A. Longer on the sunny side of the stem. B. Shorter on the sunny side of the stem . C.shorter on the shaded side of the stem .d. Longer on the shades side of the stem

Answers

Answer:

D. Longer on the shaded side of the stem

Explanation:

Auxin is a plant hormone that promotes cell growth and elongation in plant stems.

It causes the cells to grow longer on the shaded side of the stem.

This growth allows for the plant to grow in the direction of the light source it has.

So, the correct answer is D. Longer on the shaded side of the stem

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.

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.

Which of the following describes a portion of the water cycle that is not driven by
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.

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
