Answer:
Mechanical digestion involves physically breaking down food substances into smaller particles to more efficiently undergo chemical digestion. The role of chemical digestion is to further degrade the molecular structure of the ingested compounds by digestive enzymes into a form that is absorbable into the bloodstream.

Use the complementary rule: If we had a 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
4 thymine, 6 guanine, 4 cytosine
O 6 thymine, 6 guanine, 6 cytosine
О 4 thymine, 4 guanine, 6 cytosine
Question 16
6 pts
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.

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.

Scenario:
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:
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.

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.

Fmri scans have allowed us to make great advances in our understand of the roles of different regions of the brain. Suggest why this may be and give some examples of areas of research which you think might benefit from this study method
Answer:
FMRI helps to measure and map the brains activities.
Explanation:
FMRI refers to Functional Magnetic Resonance Imaging. It helps to measure and map the brain's activity.
FMRI scan works by looking at the blood flow in the brain to detect areas of activity. Glucose is the main source of energy in the brain,but not stored in the brain. So when parts of the brain need energy o perform action, more blood flow in to transport more glucose.
FMRI scan helps doctors to map out the brain before surgery and provides more information about individual brain to prevent serious injury before the surgery.
It also helps doctors monitor a progressive condition like dementia to study how the disease progresses.
