b. ozone depletion
c. carbon footprint
d. reef destruction

Answers

Answer 1
Answer: The correct answer is C. Carbon footprint is the total amount of greenhouse gases produced by individuals or other entities in a given period of time. It is usually expressed in equivalent tons of carbon dioxide. Greenhouse gases can be emitted through transport, production and consumption of food, fuel, etc.

Which nuclear decay emission has the weakest penetrating power?1. alpha particle
2. bera particle
3.gamma radiation
4. positron

Answers

Alpha particle is the nuclear decay emission that has the weakest penetrating power. The correct option among all the options that are given in the question is the first option or option "1". Gamma is a type of radiation and so can be negated as a particle. Alpha particles have the largest radiation and so the weakest penetrating power.

The muscles in the stomach aid in digestion by __________.a. secreting bile
b. churning, or mixing, food
c. opening and closing the stomach
d. absorbing nutrients

Answers

The muscles in the stomach aid in digestion by churning, or mixing, food. Hence, option C is the correct answer.

What is digestion?

Digestion is the complex process of turning the food you eat into nutrients, which the body uses for energy, growth and cell repair needed to survive.

The stomach is a muscular sac that lies between theesophagus and the small intestine in the upper abdomen.

The stomach is not the only part of your digestive system that absorbs food but rather is a part of the digestive system and important for churning food into a consistency that is easier to digest for the rest of your intestines.

Hence, option C is the correct answer.

Answer:

The answer is D

The carbon cycle involves an exchange of carbon between ___ a. the geosphere and atmosphere
b. the atmosphere and hydrosphere
c. the geosphere and hydrosphere
d. the geosphere, hydrosphere, and atmosphere

Answers

Answer:

D) The geosphere, hydrosphere, and atmosphere

Explanation:

During the carbon cycle, various processes move carbon from the geosphere to the atmosphere such as volcanic eruptions release carbon dioxide from molten rock beneath the earth's surface to the atmosphere. Carbon can leave the soil through soil respiration which releases CO2, or by erosion  which can carry it into rivers or the ocean, where it then enters the hydrosphere. Carbon is found in the hydrosphere dissolved in ocean water and lakes and hence the cycle continues.

The carbon cycle is the biogeochemical cycle which involves an exchange of carbon among the biosphere, pedosphere, geosphere, hydrosphere, and atmosphere of the Earth.

Carbon is the most important component of the biological compounds  such as limestone. Also, during soil respiration, Carbon can leave the soil through it which releases CO_(2),  which carries it into the rivers or the ocean, where it then enters the hydrosphere.

Thus, option D is correct.
