How are changes in populations related to the availability of an ecosystem's resources?A.
Changes in population are independent of the availability of an ecosystem's resources.
B.
Population sizes are limited by the amount of resources that are available.
C.
As populations grow, ecosystems produce more resources in order to support the larger population.
D.
Large populations need the same amount of resources as small populations.

Answer 1

Answer:

Answer:

Explanation:

The answer is B; there cannot be a large population in an ecosystem that only provides a small amount of food; similar to how a family of six cannot live off of the same amount of food that a single person could easily live off of. This concept rules out both A and D, and C is also incorrect because the ecosystem is independent of the population, it is not aware of the amount of organisms living it; so it cannot alter it's resources based off of what organisms live in it.

The Calvin cycle includesA. The light-dependent reactions
B. An electron transport chain
C. The light-independent reactions
D. Photosynthesis

Answers

Answer:

C. The light-independent reactions

Explanation:

Photosynthesis consists of two phases: light dependent phase and light independent phase.

a) The light dependent phase of photosynthesis includes photolysis of water, release of oxygen and synthesis of ATP and NADPH.

b) Light independent phase of the photosynthesis includes chemical pathway to fix atmospheric carbon dioxide into glucose. Since this chemical pathway was first discovered by Calvin, it is called as Calvin cycle.

Unlike red blood cells, white blood cells A. can live for many years.
B. carry oxygen through the body.
C. are the most numerous cells in the blood.
D. are made in the bone marrow.

Answers

Answer;

A. can live for many years.

Unlike red blood cells, white blood cells can live for many years.

Explanation;

-Blood has four main components: plasma, red blood cells, white blood cells, and platelets.

-Red blood cells live for only about 120 days. As they wear out and age, they are captured and disposed of by cells in the spleen and other organs.

-White blood cells are different from red blood cells in several important ways. Unlike red cells, white cells are complete cells. They are larger than red cells and have a nucleus. White blood cells are not just carried by the blood stream, they can also move about independently. Additionally, Unlike red blood cells, white blood cells can live for many years.

The answer is neither of the above. All the above features except A relate to the red blood cells. (A is not true for both red blood cells and white blood cells.)Red blood cells or RBCs carry oxygen, are the most numerous cells (36 - 50%) in the blood and they are made in the bone marrow. The life span of RBCs is 120 days or 4 months.On the other hand, white blood cells or WBCs produce antibodies to develop immunity against infections and some are phagocytic against pathogens. They make up about 1% of the blood and are produced in the thymus. The lifespan of WBCs is 4 - 30 days.

How can an injury to a peripheral nerve cause loss of both sensory and motor functions?

Answers

The reason is that peripheral nerves have both sensory and motor fibers.

Through these sensory fibers, peripheral nerves receive signal and send them to the brain. Also, through motor fibers, peripheral nerves send information to the muscles. When a peripheral nerve is damaged, the both functions will be lost.

How do large bodies of water influence climate?

Answers

Due to their characteristics, large bodies of water have a great influence on climate. By absorbing and releasing heat, they regulate temperature, resulting in milder conditions closer to the coast.

Through wind and ocean currents, heat is redistributed, causing warming or cooling of nearby regions. Bodies of water evaporating into the atmosphere add moisture to the air, leading to cloud formation and increased precipitation.

Due to oceanic influence, the coastal places get frequent weather with low temperature extremes. Large stores of water can also influence global phenomena such as the El Niño–Southern Oscillation, which affects global weather patterns. The exact effects vary according to factors such as proximity, size, ocean currents, prevailing winds, and regional geography. Large-scale water bodies are fundamental in determining regional and global climate trends.

large bodies of water affect climate because water heats and cools more slowly than land therefore in the summer the coastal regions will stay cooler and winter warmer. A moderate climate with a smaller temp range is created
