Answers

Answer 1

Answer:

Answer:

Option 3. The proportions of DNA bases are similar among all organisms.

Explanation:

The DNA is composed of two nitrogen bases called the nucleotide and four nucleobases joined by hydrogen bonds namely:

Adenine (A) 2. Guanine(G) 3. Cytosine (C) 4. Thymine (T)

The proportion and the number of the bases and base pairing are the same in all organisms but what makes an organism different is the order in which they're arranged.
The DNA coding depends on the order of gene expression determined by a specific arrangement of DNA molecules in each organism.
Out of the 3 billion bases found in humans 99% of the bases are similar in all.

D) bacteria and algae

Identify the fuel that could be classified as a nonrenewable or renewable resource.
A) biomass
B) geothermal
C) wind
D) tidal

Answers

c removing salt and minerals

the process of desalination removes salt and minerals so water is safe to drink

A Biomass

This is because it is easily replenished naturally and over a short period of time but only if there is a large quantity of biomass available. If there is little biomass than it will be nonrenewable.

How many chromosomes does each new cell contain after mitosis if the original cell had 52 original cell chromosomes

Answers

First of all, there are 46 individual chromosomes (23 pairs) in a human cell.

What happens in mitosis is that the original cell copies its DNA (so there are 2 sets of 23 pairs. In the end, after cytokinesis takes place, each daughter cell will have 23 pairs (46 chromosomes).
