Explanation:

The introduced species is also called as an exotic species. The exotic species is a species which is not native to a particular location or area but is introduced by humans either accidentally or with the desired species. Such species can be invasive means, it can compete with the native species for resources and can reduce the population of native species.

Give an example of exaptation in humans.

Answers

Answer:

As an example of an exaptation, Gould (1991) used the large size of the human brain and its function of enabling humans to produce speech. The large brain size, according to his argument, originally arose as an adaptation for some (unspecified) functions in humans' ancestral past ( Gould, 1991 ).

Answers

Answer: 50% with dimples and free earlobes and 50% with dimples and attached earlobes

Explanation:

Since both the facial dimples and free earlobes are considered to be dominant human traits, this implies that the expected phenotypes of the offspring with regards to the scenario given in the question would be 50% with dimples and free earlobes and also there will be 50% with dimples and a attached earlobes.

50% with dimples and free earlobes and 50% with dimples and attached earlobes.

Dominant and recessive traits exist when a trait has two different forms at the gene level. The trait that first appears or is visibly expressed in the organism is called the dominant trait. The trait that is present at the gene level but is masked and does not show itself in the organism is called the recessive trait.

Since both the facial dimples and free earlobes are considered to be dominant human traits, this implies that the expected phenotypes of the offspring with regards to the scenario given in the question would be 50% with dimples and free earlobes and also there will be 50% with dimples and an attached earlobes.

define thigmotropism, phototropism, and gravitropism and give an example of each​

Answers

Answer:

a) Thigmotropism

b) Phototropism

c) Gravitropism

Explanation:

A) the turning or bending of a plant or other organism in response to a touch stimulus. example:  the folding movement of the Mimosa pudica leaflets, can be considered as an example of thigmonastism.

B) the orientation of a plant or other organism in response to light, either towards the source of light ( positive phototropism ) or away from it ( negative phototropism ).example: Sunflower is a highly phototropic plant. They grow towards the sun and are also seen tracking the movement of the sun throughout the day. That is, the flower keeps changing its direction with the movement of the sun. Sunflower requires more light for its growth and survival.

C) The gravity-directed growth process, called gravitropism, dictates upward shoot growth to ensure a proper positioning of the leaves for efficient photosynthesis and gas exchange. example: tree has fallen over and due to gravitropism exhibits this arched growth.  

A lake has very deep water at the bottom, in the benthic zone. Why is it more difficult for plants to live in the benthic zone of this lake than in the limnetic zone

Answers

Answer:

See the answer below

Explanation:

It is quite difficult for plants to survive in the benthic zone due to the limited penetration of light in the zone when compared to the limnetic zone. The limnetic zone is a well-lit area of a lake or pond while the benthic zone represents an area around the bottom of any water body - marine or freshwater.

Light is an important factor for plants because the light is necessary for photosynthesis - a process through which plants get their foods. Hence, due to limited light in the benthic zone as opposed to the limnetic zone, plants would find it easier to survive in the latter compared to the former.

Why is energy transformed from one form to others?

Answers

Answer:

Energy transformation is when energy changes from one form to another – like in a hydroelectric dam that transforms the kinetic energy of water into electrical energy. While energy can be transferred or transformed, the total amount of energy does not change – this is called energy conservation.

In fission, how does the DNA of the daughter cells compare to the DNA of the parent cells?

It is exactly the same

It is different due to meiosis

It it mostly the same with slight changes

It is better than the parent DNA

Answers

Answer: It is exactly the same!

In fission, the DNA of the daughter cells compared to the DNA of the parent cells will be exactly the same. The correct option is A.

What do you mean by a parent cell and a daughter cell?

The cell that divides to produce two daughter cells is known as the mother or parent cell in the process of cell division. Mitosis produces two offspring cells that are genetically identical to the mother cell. We are all alive now due to a process known as mitosis.

Mitosis is the process through which a single cell divides into two new, identical cells. The initial cell is known as the parent cell, while the newly created cells are known as the daughter cells.

The daughter cell is exactly identical to the mother cell, that's why the DNA will also be the same in both cells.

Therefore, the correct option is A. It is exactly the same.
