Correct me if I'm wrong but I'm pretty sure it is B.
Answer: Vena cava also know as (SVC).
Explanation: Blood provides oxygen and nutrients to the body and removes carbon dioxide and wastes. Oxygen-poor blood returns from the body to the heart through the superior vena cava also know as (SVC) and also inferior vena cava (IVC), these are the two main veins that bring blood back to the heart.
Answer:
DNA is made up of molecules called nucleotides. Each nucleotide contains a Sugar group, phosphate group, and a nitrogen base. The four type of nitrogen bases are thymine (T), cytosine (C), guanine (G), adenine (A). The order of these bases is what determine DNA.
Explanation:
Homeostasis is the tendency to resist change in order to maintain a stable, relatively constant internal environment.
In DNA replication, <u>adenine</u> pairs with thymine, and cytosine pairs with <u>guanine</u>.
In the field of science, DNA replication can be described as a process by which DNA makes copies of itself.
DNA is made of four nucleotide bases, deoxyribose sugar, and phosphate groups. The four nucleotide bases present in the DNA are adenine, guanine, thymine, and cytosine.
Adenine and guanine are nucleotide bases that have two carbon-nitrogen rings and are referred to as purines. Thymine and cytosine are made of one carbon-nitrogen ring and are referred to as pyrimidines. In the DNA, adenine pairs with thymine, and cytosine pairs with guanine.
