1) Birthrate. Because you need to accommodate for all the little humans on earth, whether that be housing or taxes and such. Plus we don’t want overcrowding in certain areas.
2) death rate. It’s important to look at the death rate of a population because it can show the condition quality of certain areas. If a place has a higher death rate or the rate increases too quickly, then that should signal that something is wrong.
Answer:
Heterotrophs
Explanation:
A heterotroph is an organism that eats other plants or animals for energy and nutrients.
Answer:
Option-B
Explanation:
Color deficiency is a condition caused when the person is not able to distinguish the different colors. Since the person is not able to distinguish different color, therefore, the chromo-receptors which are affected are the cone cells located in the retina which allows us to see different wavelengths.
1. Total color blindness is not a rare disease in animals.
2. Total color blindness in which a person is not able to see any color occurs when all types of cone cells become malfunction or completely absent.
3. The red-green color blindness is more common than the blue-yellow color blindness.
4. The mother is usually not affected as she is the carrier of the gene responsible for the color blindness.
Since all options except Option-2 are incorrect therefore option-2 is the correct answer.
1. Pathogens enter the body through a cut in the skin
2. Cells recognize the foreign invaders
3. Histamine is released
4. White blood cells travel to the invaded area
Hope it helps.
Answer:
The label A corresponds to Convergent boundary zones
Explanation:
When two oceanic plates collide, it occurs oceanic convergence. The thicker and older plate subduces under the other plate, and at this point, it starts the volcanic activity. As the thicker plate descends, it is heated and melted and its materials are incorporated into the mantle. The fast subduction originates magma that ascends to the surface by crevices. This makes place to the formation of grouped <u>volcanic islands</u>, t<u>he island arches</u>. Subduction zones coincide with deep-sea <u>trenches</u> or depressions in the ocean bed. The volcanic islands are arranged in a circumference arch shape, which is bordered by a fossa. Most of these are located in the western Pacific, where the pacific crust is older and thicker, and hence it submerges easier in the mantle.
