Answer: Option C

Explanation:  There is only a certain of DNA that is unique in the organism. Rest of the DNA is same in all the organism.

Suppose at any crime place where there is some evidence having the DNA , this DNA sequence is matched with the DNA sequence of the criminal. This of the DNA is used in the DNA fingerprints to detect the person having the same DNA sequence. The matched sequence of DNA will be of criminal.

So, this is how the DNA fingerprints can be used in many cases as it is unique in the organisms.

5. One of the most important steps to achieve a more sustainable future is to reduce a. Water conservation b. Overconsumption c.
kykrilka [37]

Answer:

B.

*Read the explanation plz

Explanation:

A actually increases sutainability, and C is just wrong. It's technically saying that we should not let humans be born, we shouldn't let people get pregnant, which of course no one is gonna listen to. So B is right because if we consume too many things, the next generation won't have as many resources as they need to survive.

Explanation:

  1. In mechanical digestion, the teeth grind food and break it in to smaller parts.
  2. Churning and the enzyme pepsin break down protein in the stomach.
  3. The pancreas releases the enzymes trypsin and chymotrypsin.
  4. Trypsin and chymotrypsin act on the proteins to break them down in the duodenum.
  5. Amino acids are absorbed by the capillaries in the jejunum.
  6. Amino acids enter the bloodstream and are circulated throughout the body.

Further Explanation:

Food is chemically and mechanically broken down into into smaller particles. This begins in the mouth, where food is mechanically crushed by the teeth, and mixed with saliva to allow water based enzymes like lingual lipase to work;- it's then transported to the stomach via the esophagus. Next in the stomach the enzyme gastric lipase acts on lipids, breaking them up into their components.

In the stomach, the enzyme pepsin breaks proteins, like those found in salmon, into smaller peptides by splitting the peptide bonds holding the proteins together. In the stomach, the enzyme pepsin breaks proteins, into smaller peptides by splitting the peptide bonds holding the proteins together.

The duodenum processes these newly-formed peptide chains or polypeptides, into smaller ones, through the enzyme action of elastase, trypsin and chymotrypsin; these are produced in the pancreas. Peptidases convert these fragments into amino acids for absorption into the bloodstream via the small intestines.

After digestion, the process of absorption occurs within villi of the small intestine; this occurs within the jejenum. Villi are small finger-like projections from epithelial cells of the small intestine; due to the projections, they have increased surface areas for absorption. Absorption involves several processes such as:

  • endocytosis
  • passive diffusion
  • facilitated diffusion
  • active transport
  • secondary active transport (co transport)

The nutrients are then taken up into the bloodstream via capillaries, and circulated through the body

What is the anatomy of a flower provide a brief explanation of the structures involved in pollination and fertilization?
ella [17]
A flower has the following:
Petals - segments of the flower
Sepal - outer parts of the flower at the bottom covered in bud
Stamen - produces pollen in the flower
Anther - where pollen is produced
Pistil - produces ovary of the flower
Stigma - where pollen germinates

Pollination occurs when insects like bees and butterflies transfers the pollen from one flower to another. Once transferred, fertilization begins.
