Students are studying bushes found in deserts and grasslands. They find that some bushes with yellow flowers looked very similia

r, but when looking at the leaves, they notice small differences. The cresosote bush is found in deserts and has small leaves with a thick waxy coating. The St. John’s wort bush is found in cooler climates and has small leaves that are much thinner and appear to have very little waxy coating. Which of the following best explains this differences between the St. Johns wort and Cresosote bush?
The plants use photosynthesis differently so their leaves have different amounts of chloroplasts.
The plants are exposed to different amounts of sunlight so the leaves have changed to produce more flowers.
The plants grow in different environments and have adapted to the climates they grow in.
There are different chemicals invloved in photosynthesis for each plant, resulting in changes. PLz Hurry CAN ANY ONE ANSWER THIS I WILL GIVE A LOT OF POINTS

Answer: the plants are adapted to different climates. The waxy coating is thick on the desert plant as an adaptation to conserve water.

Explanation: Both plants live in full sun, so have similar exposure and similar levels of chloroplasts, no difference that alters flowering. Both plants are C3 type photosynthesisers, with the same photosynthetic system.

compare the thickness of the wall of the superior and inferior vena cava and the aorta. which thicker and why????
Irina-Kira [14]

Answer:

The wall of the aorta is thicker than that of the inferior venacava; this is because the aorta is the artery that carries blood from the heart from the left ventricle to the whole body (except the lungs), while the superior and inferior venacava are the veins that carry blood from the body to the right atrium. hope this helps ! :)))

Explain why and how the layers have changed from one cliff face to the next
Nesterboy [21]

Layers have shifted from one cliff to the next because all cliffs are formed, in one way or another, by the movement of tectonic plates.

<h3>What is a cliff?</h3>

An escarpment, in geomorphology, is a landform that is a transition area between different physiogeographic provinces that involves an acute elevation (greater than 49º), characterized by the formation of a cliff or a steep slope. The term comes from the Italian scarpa.

Whit this information, we can conclude that layers have shifted from one cliff to the next because all cliffs are formed, in one way or another, by the movement of tectonic plates.

Chap 2.3 biology;;
Murrr4er [49]

Answer:

Monomer: 2 - Amino acid

                 3 -Nucleotide

Polymer: 1 - Cellulose

               3 - Nucleic acids

Example: 1 - Carbohydrates

               2 -  Collagen

Function 1: Carbohydrates are a source of energy in the body.

Function 2: Collagen is the most abundant protein in the human body. It's a long, fibrous structural protein that supports tissues and gives structure to individual cells. Collagen fibers are tough and found in bundles. They providing tensile strength to the tissues containing them.

Function 3: DNA is a protein structure that carries instructions needed for an organism to develop, survive and reproduce. It is a nucleic acid that contains the genetic instructions for the development and function of living things, its main role is the long-term storage of information

Explanation:

Monomers are single molecules that can bond with identical molecules to form polymers.

1. Glucose can combine with other glucose molecules to form starch or cellulose which results in formation of carbohydrates.

Carbohydrates are a source of energy in the body.

2. Amino acids can combine with other amino acids to form a protein chain which results in formation of collagen

Collagen is the most abundant protein in the human body. It's a long, fibrous structural protein that supports tissues and gives structure to individual cells. Collagen fibers are tough and found in bundles. They providing tensile strength to the tissues containing them.

3. Nucleotides can combine to form nucleic acids resulting in formation of enzymes.

DNA is a protein structure that carries instructions needed for an organism to develop, survive and reproduce. It is a nucleic acid that contains the genetic instructions for the development and function of living things, its main role is the long-term storage of information
