Which reason best explains why living things need carbon? Carbon is a source of energy. Carbon reduces global temperatures. Carbon is an important solvent. Carbon is everywhere.

Answers

The answer is Carbon is a source of energy. 

Plants absorb carbon dioxide and make carbohydrates in a process of photosynthesis. Carbohydrates have many C-H bonds which breaking down releases such amount of energy. Also, lipids are the macromolecules with the highest number of carbon-hydrogen (C-H) bonds, so they contain more C-H bonds than carbohydrates. So, carbon is the part of macromolecules containing potential energy in the form of C-H bonds. At the end, carbon is the source of energy.

Why is the weight of an object more on Earth than on the Moon?The Moon is a satellite of Earth.
The gravitational pull of the Moon is greater than that of Earth.
The gravitational pull of Earth is greater than that of the Moon.
The object’s mass is different on Earth and on the Moon.

Answers

The correct answer is:

Gravitational pull is greater on earth . As weight = mass × g so we have more weights on earth than on moon.

Explanation:

This is because gravitational force is immediately proportional to the mass of an object. Greater the mass, greater will be the gravitational force exerted by it and thus, more will be our weight. As the moon has secondary mass than the earth, it has a lighter gravitational influence and hence, we weigh less on the moon.

The correct answer is...

The gravitational pull of Earth is greater than that of the moon.

The reason tropical deforestatio is worse than temperate deforestation is because there is a. there is more carbon in the ground in temparate forests
b. more carbon in tress in temperate forests
c. rates of photosysnthesis are higher in temperate forests

Answers

Answer:

Option A, there is more carbon in the ground in temparate forests

Explanation:

In temperate forests the nutrients are mostly found in the soil including the carbon, while in case of tropical forests these nutrients (including carbon) are up taken by the trees and stored there itself. Now when the tropical forest trees are cut down the carbon reserves with in the trees is  destroyed and released in the atmosphere. As per estimate the amount of carbon released by deforestation of tropical forest is much more disastrous than the gas emission of automobiles and industries in the current time.

Hence, option A is the correct choice of answer
I believe C is the correct answer.

Microorganisms can mutate and evolve very quickly compared to most multicellular organisms. This allows pathogenic microorganisms to infect new species. Suppose a very harmful microorganism that is quite successful at infecting hardwood trees is introduced into a forest ecosystem. What effect would this pathogenic microorganism most likely have?

Answers

Answer: It would disrupt the ecosystem by greatly reducing the population

of a few species.

Explanation: If a few species are affected the multiplying effect can be devastating.
it would most likely infection the forests and probably even mutate to be able to infection animals that live in the forest

Cells of the immune system are able to respondto the presence of invading organisms because
they recognize the
(1) antigens present on the invaders
(2) antibodies present in invading pathogens
(3) DNA pattern in the nuclei of viruses
(4) antibiotics released from microbes

Answers

1.  antigens present on the invaders

Through the antigens present to the invaders the Cells of the immune system can easily able to respond and recognize.  During an infection, chemical signals attract phagocytes to places where the pathogen has invaded the body. 

Answer:1) antigens present on the invaders

Mice that have been given morphine are very likely to develop blood poisoning because bacteria that normally reside in the intestine typically respond to morphine by migrating into the bloodstream. However, when mice are given both morphine and the new drug naltrexone, blood poisoning is much less frequent, although it does still occur. These results provide support for researchers’ prediction that naltrexone will turn out to be toxic to certain types of bacteria. Which of the following, if discovered to be true, would most seriously weaken the support for the researchers’ prediction? A. After being administered to mice, naltrexone does not pass from the bloodstream into the intestine. B. Naltrexone inhibits morphine from triggering the migration of intestinal bacteria into the bloodstream. C. Mice that have been given naltrexone but not morphine have no greater risk of developing blood poisoning than do mice that have not been given either substance. D. The increased risk of blood poisoning is not the only harmful effect on mice of being given morphine. E. Conditions other than the presence of intestinal bacteria in the bloodstream can cause blood poisoning in mice
