Surface runoff is increased by deforestation. Details about surface runoff can be found below.

Surface runoff is the overland flow of excess water (with or without accumulated contaminants) that cannot be absorbed by the ground as infiltration.

Surface runoff has adverse effects on the soil and crops.

Deforestation exposes the bare soil, hence, is likely to cause surface runoff.

The vascular tissues identify as:

a. phloem

b. xylem

Vascular tissues in plants are specialised tissues which transport nutrients and water through the plant. They are made up of two distinct kinds of tissues: xylem and phloem.

Xylem is in charge of carrying water and minerals that are dissolved from the plant's roots to its leaves. It is made up of many cell types, such as tracheids, vessel components, and fibres. Tracheids and vessel elements are long, hollow structures that create lengthy tubes when stacked end to end.

Sugars and other organic compounds are transported from the leaves to the remainder of the plant by phloem. There are two sorts of cells in it: sieve tube elements and cell companions. Sieve tube components are long, narrow cells that run end to end.

Therefore, the vascular tissues identify as:

a. phloem

b. xylem

The first law of energy can be applied in food processing whereby foods are converted from one form to another.

Food processing is the process by which food is converted from its natural state obtained from plants to a more edible and palatable state for consumption by humans.

The first law of energy states that energy cannot be created nor destroyed but can be converted to other forms.

The central dogma is the process of the formation of the protein from DNA. The polypeptide chains formed from mRNA are produced through translation. Thus, option a is correct.

The translation is the central dogma process that translates the transcripted mRNA copy into amino acids that interlink with peptide bonds to produce polypeptide chains. Translation occurs outside the nucleus.

The duplicated DNA undergoes transcription to produce an mRNA copy that gets transported to the ribosome that translates the mRNA with the help of the tRNA and rRNA to yield chains of amino acids that produce proteins.

Therefore, the mRNA is transported to the ribosome and gets translated to proteins through the process of translation.

The rabbits would be classified as exotic invasive species.

Invasive species are plant or animal species that disrupt the ecological balance of ecosystems by their invasive attributes.

Invasive attributes include the ability to spread or multiply at a fast rate, sometimes secreting biological chemicals to inhibit the growth of other species.

Exotic invasive species are invasive species that are introduced, rather than being native to the ecosystem.

Thus, the rabbits can be classified as exotic invasive species.

A law is something in science that can be proved through experimenting. When the experiment is done properly, the same outcome will be achieved every time. A law does not attempt to explain why something is the way it is, it only states it.

A theory is an idea that has a large amount of scientific data backing it and is the accepted answer by most scientists, but there is no way to experiment on a scientific theory. A theory will never be able to become a law. A theory explains what it is describing.

Answer:

A.carbon dioxide

Explanation:

oxygen poor blood means the blood is rich with Carbon dioxide

The oxygen poor blood delivers to the lungs carbon dioxide out of the body organs and cells. Thus, the correct option is A.

The heart is divided into two separate pumping systems, which include the right side and the left side. The right side of the heart receives oxygen-poor blood that is deoxygenated blood from the veins and pumps it to the lungs, where the blood picks up oxygen gas from the alveoli and gets rid of carbon dioxide gas.

Deoxygenated blood has less oxygen or it is oxygen-poor and contains is carbon dioxide rich. The right heart pumps this deoxygenated blood to the lungs where it picks up additional oxygen gas.

As the blood travels through body, oxygen gas is used up, and the blood becomes oxygen poor or carbon dioxide rich. Oxygen-poor blood returns from the body to the heart by the superior vena cava and the inferior vena cava, the two main veins which bring blood back to the heart.

Therefore, the correct option is A.
