How does carbon become locked inside the earth?

A) tree roots expel carbon into the soil as they grow

B) humans use machines to pump carbon into large underground tanks

C) rocks become richer in carbon as time goes on

D) the carbon-rich bodies of plants and animals decay into the earth after they die

a) tree roots expel carbon into the soil as they grow.

Explanation:

Roots offer physical anchoring to the soil of the tree, with water uptake and inorganic nutrition as its principal activity.

The absorption and the transfer of ions and the growth and maintenance of the roots themselves require energy, therefore releasing CO2 into the ground and into the air.

A diverse ground microbiota exists underneath the earth in addition to the plant roots. Their work results in carbon dioxide being released into the soil, which flows into the air. This soil microbiota is responsible for decomposing the litter and, in general, any dead organic matter in the soil. It may breathe more than half of the total soil respiration. Soil temperature and humidity strongly affect root and microbial activity. In warm and moderately moist soils, soil breathing is highest.

the answer is; comparing the frequency of collisions with and without the device

this makes the anti-collision system an independent variable and the collisions a dependent variable. if there are fewer collisions with an anti-collision system that without, then it can be stated that the system is a success. essentially, collisions under an anti-collision system are compared with the frequency of collisions by cars with the human drivers.

answer: although many types of viruses can cause a common cold, rhinoviruses are the most common culprit. a cold virus enters your body through your mouth, eyes or nose. the virus can spread through droplets in the air when someone who is sick coughs, sneezes or talks. theres your answer
