The third one,
Autotrophs use a process called photosynthesis to make their food. In photosynthesis, autotrophs use energy from the sun to convert water from the soil and carbon dioxide from the air into a nutrient called glucose. Glucose is a type of sugar. The glucose gives plants energy. Plants also use glucose to make cellulose, a substance they use to grow and build cell walls.

a single stranded dna (oligonucleotides) can hybridize with (select one): select one: a. complementary dna b. complementary rna
garri49 [273]

A single stranded DNA  (oligonucleotides) can hybridize with (d) both complementary DNA and complementary RNA.

DNA is the Deoxyribonucleic Acid. It is the genetic material present in majority of organisms. The nitrogenous bases present in DNA are: Adenine, thymine, Guanine and Cytosine.  DNA is a double stranded structure hence it forms hydrogen bonds with a complementary strand. The complementary strand can be of a DNA or RNA.

RNA is the Ribonucleic Acid. It also is a genetic material present in very few organisms. RNA is less stable than the DNA and may be either single stranded or double stranded. The nitrogenous bases of RNA are: Adenine Uracil, Guanine and Cytosine.

Explain how the circulatory system is able to transport the blood under high pressure from the heart to the rest of the body
expeople1 [14]

Transport of blood under high pressure is done through the concerted efforts of the heart and arteries.

<h2>The circulatory system is the network of the heart, arteries, veins, and capillaries responsible for the movement of blood around the body.</h2>

Transporting blood under high pressure can be explained in the following steps:

  1. Contraction of the heart ventricles creates blood under high pressure
  2. High pressured blood is removed from the heart through the arteries. In addition, the arteries are able to contract and expand, thus are elastic
  3. The lumen of the arteries is narrow thus helping in maintaining high pressure

As a result of the above, the high pressure of blood is maintained and transported to the extremities of the body.

As DNA replication continues and the replication bubble expands, the parental double helix is unwound and separated into its two
liberstina [14]

Answer:

A. Helicases

B. Single strand binding proteins

C. Single strand binding protein

D. Topoisomerases

Explanation:

The helicases bind on the replication fork aiding in the unwounding of the DNA helix to allow for replication. The single strange binding proteins attach/bind to the separated single stranded DNA after the replication fork to prevent re-annealing of the single stranded DNA preventing Hydrogen bond formation that reanneals these two strands together. The topoisomerases are found just ahead of the replication fork preventing overwounding/ positive supercoils of the DNA. They do this by introducing breaks into the phosphate backbone of the DNA allowing them rotate forming negative supercoils and attaching the breaks once the DNA strand is relaxed.
