A pair of human mother and her child belongs to the same population.

What is population?"Individuals of any species live in groups in a well defined geographical area, share or complete for similar resources, potentially interbreed and thus constitute a population."

A dog and a cat, a marigold and a geranium and a spider and a cockroach do not share similar resources and they don't interbreed so they do not belong to the same population.

Hence, the correct option is C. a human mother and her child.

One way I can prevent myself.

Answers

Answer:

i dont understand you're qiestion

Glucose can pass through the semi permeable membranes where the molecules can pass because they are soluble in water enough. The  molecules can pass through because of the solubility factors.

What is a semi permeable membrane ?

It is the semi permeable membrane where the half of the molecules get passed through the membrane. The molecules are selectively present.

Cell membranes are an example of semi-permeable membranes. Cell membranes allow small molecules such as oxygen, water carbon dioxide and glucose to pass through, but do not allow larger molecules like sucrose, proteins and starch to enter the cell directly.

Transport is helped by certain molecules as well where the few of the ions, channels and the molecules are taken up by the membrane through the selected transportation of the ions.

What is the manipulated variable in this experiment?
O A. The distance the snails moved
OB. The size of the petri dishes
C. The temperature of the water
D. The number of snails observed HELP ME

Answers

The correct answer is C. The temperature of the water

Explanation:

In an experiment such as the one described about the speed of snails in water, the manipulated variable is the factor or element that is manipulated on purpose. This means the researcher or researchers slightly change this element to compare how this affects another variable. In this context, the manipulated variable is the temperature of the water because researchers used three different temperatures (cool, room-temperature, and warm), and therefore they manipulated or changed this factor. Moreover, it is expected temperature affects the distance nails move, which is the main variable.

PLEASE HURRY,(GIVING BRAINLIEST) (THE ACTUAL SUBJECT IS SCIENCE)After a major forest fire kills all of the plants in an area, the first plants to grow in the burned area are often types of grass. Because they are the first thing to grow in the new ecosystem, these types of grass are called pioneer species. What adaptations would help the grass be a successful pioneer species?

A.

slow reproduction and the ability to grow in sunny places

B.

rapid reproduction and the ability to grow in sunny places

C.

slow reproduction and the ability to grow in shady places

D.

rapid reproduction and the ability to grow in shady places

Answers

Answer: B

Explanation:

To help the pioneer species to grow, it needs to have rapid reproduction. But, it also needs the sun to grow very well. If it does not have the Sun, it will most certainly die and be endangered in the area. The answer is B, we need both rapid reproduction and the Sun.

Answer:

rapid reproduction and the ability to grow in sunny places

Explanation:

After a major fire, less sunlight is blocked by trees and other plants. Plants that can use the increased sunlight are more likely to thrive in the new environment. Rapid reproduction would help a plant species to spread more quickly to take advantage of the resources and lack of competition. Therefore, the adaptations that would help grass be a successful pioneer species are rapid reproduction and the ability to grow in sunny places.
