Hope this helps :)

Eukaryotic species' mitochondria are the "engine room" of cellular respiration. Therefore, option (C) is correct.

What is cellular respiration?

The metabolic process known as cellular respiration involves the use of oxygen in the breakdown of macromolecules such as carbohydrates, lipids, and proteins in order to produce adenosine triphosphate (ATP) (ATP).

Glycolysis, the citric acid cycle, and oxidative phosphorylation are the three primary stages that are involved in the process of cellular respiration.

Mitochondria are frequently referred to as the "engine room" of eukaryotic organisms. This is because they are the principal place for cellular respiration, which is a necessary process.

A ____ is the structure that contains the DNA of the cell.

Centriole?
Chromosome?
Cytoplasma?
Vacuole?

Answers

Answer:

Option C

Explanation:

Nucleus contains nucleolus and nucleolus contains chromosomes and chromosomes contain DNA.

Chromosome is the  cellular structure which  contains DNA of the cell.

What is DNA?

DNA is a hereditary material which is present in human beings as well as all other living organisms.  Every cell which is present in an organism's body has DNA  which is the same. Most of the DNA is situated in the cell's nucleus  and small amount of it can be found in the cell's mitochondria as well.

Information which is stored in DNA is stored as codes made up of four chemical bases namely, adenine, thymine , cytosine and guanine.Human DNA consists of 3 billion bases .The order of the bases determines information which is required for building and maintaining an organism.

DNA bases are capable of pairing up with each other. Adenine pairs with thymine and guanine pairs up with cytosine .Each base is also attached to a sugar molecule  and a phosphate group. A base, phosphate  sugar are together called as nucleotides.

Sandy heard that plants compete for space. She decided to test this idea. She bought a mixture of flower seeds and some potting soil. Into each of 5 plastic cups she put the same amount of soil. In the first cup she planted 2 seeds, in the second cup she planted 4 seeds, in the third cup 8 seeds, and in the fourth cup she planted 16 seeds. In the last cup she planted 32 seeds. After 25 days, she determined which set of plants looked best.

Question:

Hypothesis:

Answers

Answer:

the answer is the first pot that contain at least two seeds.

Explanation:

this is because you already know that plants compete for space. so the lesser the seed the more nutrients it will need to grow then expose it to sunlight, water and air. it will grow well and look healthy.

4 thymine, 6 guanine, 4 cytosine
O 6 thymine, 6 guanine, 6 cytosine
О 4 thymine, 4 guanine, 6 cytosine
Question 16
6 pts

Answers

Answer:

6 thymine, 4 guanine. 4 cytosine

Explanation:

Adenine pairs with thymine, so you need 6 of each

Cytosine matches with guanine, but the total of nucleotides is 20, so

6(adenine)+6(thymine)=12

20-12=8

8= 4(guanine)+4(cytosine)

DNA strand of 20 nucleotides, and 6 of them were adenine, how many thymine, guanine, and cytosine would we have 6 thymine, 4 guanine, 4 cytosine.

What is DNA strand?

Deoxyribonucleic acid, also known as DNA, is the molecule that carries the genetic material necessary for an organism's growth and operation. The structure of DNA is a double helix, which is made up of two connected strands that loop around one another to resemble a twisted ladder.

Deoxyribose and phosphate groups alternately form the backbone of each strand. One of the four bases—adenine (A), cytosine (C), guanine (G), or thymine—is joined to each sugar (T). Adenine forms chemical bonds with thymine while cytosine forms chemical bonds with guanine to join the two strands together.

A protein or RNA molecule's construction instructions are among the biological information encoded by the nucleotide sequence along the DNA backbone.

Therefore, DNA strand of 20 nucleotides, and 6 of them were adenine, how many thymine, guanine, and cytosine would we have 6 thymine, 4 guanine, 4 cytosine.

A business is defined as a company or organization that engages in commercial, industrial, or professional activities.

Businesses can be either for-profit or non-profit organizations. Limited liability companies, sole proprietorships, corporations, and partnerships are all examples of business structures.

A business purpose describes the reason or purpose for which a company was founded.

It describes what makes a company unique as well as what the company intends to do. A business purpose is not the same as a mission or value statement, and it is much shorter.
