When we doing Strawberry Extraction, why do we need to remove the air as much as possible before seal the bag?

Answers

to keep it preserved and delicious

Answer:

Why do we need to cool the mixture? DNases or restriction enzymes that destroy DNA are present in the cell's cytoplasm. They are there to protect the cell from invasion by viruses. Once the nuclear membrane is destroyed by the soap, the DNA is now susceptible to the DNases and will quickly be degraded.

Explanation:

When you added the salt and detergent mixture to the smashed strawberries, the detergent helped lyse (pop open) the strawberry cells, releasing the DNA into solution, whereas the salt helped create an environment where the different DNA strands could gather and clump, making it easier for you to see them.

Answers

Answer:

the answers are

1) b

2)c

3) a

Water vapor needs cool air, dust particles, and humidity to become rain or snow. Thus, the correct option is D.Water droplets fall because they are too heavy. Thus, the correct option is C.Snow is formed when water droplets form ice crystals. Thus, the correct option is A.

What is Water vapor?

Water vapor may be defined as the gaseous form of water that is usually dispersed across the atmosphere with the help of wind. This state of water is significantly found in the hydrosphere.

This gaseous form of water is formed from the evaporation or boiling of liquid water or from the sublimation of ice.

Water vapor requires to combine with dust particles and cool air along with atmospheric humidity in order to produce rain or snow. Due to the combination of such compounds, water droplets become too heavy.

Snow or ice is the solid appearance of water which is usually formed from the compaction of crystallized structure.

Therefore, each of the above questions is described.

Explanation:

Why can mRNA leave the nucleus, but
DNA cannot leave the nucleus?
A. DNA is single stranded and is too long to leave the
nucleus.
B. RNA is singled stranded, DNA is double stranded, so
RNA is smaller than DNA.
C. DNA can leave the nucleus through special openings in
the nuclear membrane.
D. DNA and RNA can both leave the nucleus.

Answers

Answer:

B

Explanation:

Your DNA is stored in a double helix formation. Which means it has two long strands and would be too long to leave the nucleus. C and A are incorrect. DNA is double stranded, so we can eliminate A. There are NO special openings in the nucleus. Only the cell membrane. C is eliminated.

Option D is incorrect because DNA is transcribed into the cell membrane, there is no way for it to leave. RNA is a single strand.

mRNA can leave the nucleus, but DNA cannot leave the nucleus because RNA is single-stranded, and DNA is double-stranded, so RNA is smaller than DNA. Thus, the correct option for this question is B.

What is DNA?

DNA stands for Deoxyribonucleic acid. It may be characterized as a type of molecule inside cells that contains the genetic information responsible for the development and function of an organism. These molecules allow this information to be passed from one generation to the next.

DNA is not a single-stranded structure. While RNA is present in a single stranded form in the cell. Due to this, the double-stranded structure of DNA seems longer than that of RNA to cross the nuclear membrane in the cell. As a result of this, RNA can easily leave the nucleus but DNA couldn't.

Therefore, mRNA can leave the nucleus, but DNA cannot leave the nucleus because RNA is single-stranded, and DNA is double-stranded, so RNA is smaller than DNA. Thus, the correct option for this question is B.

1. Submit your observations of the chicken leg dissection.



2. Were you able to determine how the chicken moves?



3. What characteristics of muscles help you determine the direction of the movement?

Answers

Answer:

1. Submit your observations of the chicken leg dissection.

The first thing that I saw was the skin. This one has bumps on it. Underneath, when I carefully cut it, I could see a yellow layer which is fat. Under the fat, there is a thick pink tissue, the muscles. The muscle is in contact with the bones and attached to them by the tendons. They look thin and white and are at the muscles' ends since they attach them to the bones.

2. Were you able to determine how the chicken moves?

Yes, muscles work in pairs, so when I pull from a specific tendon, the leg bends since the muscle contracts to do this movement. Then this muscle will relax, another muscle will contract itself, and a tendon will pull the bone to return the leg to a straight position.

When one of these muscles contracts, the other relaxes to allow the bone's movement in a specific direction. Then this muscle relaxes and allows the leg's movement in the opposite direction since the muscle that was lax before now is contracting itself to extend the leg. There are a flexor and an extensor muscle.

3. What characteristics of muscles help you determine the direction of the movement?

The characteristics that help me determine the movement's direction were:

The position that the muscles have concerning the joints and the bones. The tendons at the end of the muscles and bones.

By following the muscle, the tendon, and where it is in the joint, I could determine the movement's direction.

Explanation:

When we observe a chicken leg dissection, we can determine the components that it has and how all the elements work together to move the leg. Even though the mechanism and structure are not the same as in a human body, we can see how muscles, bones, tendons, and joints work not only in animals but also in humans to allow movement.

is co-dominant; FF have pink feathers, PP have purple feathers and mottled diriclaws (FP)
have both pink and purple feathers. Pink feathered diricrawls are very rare and prized by
collectors. If you breed a pink diriclaw with a mottled diricrawls, what percentage of their
offspring will be pink feathered? (show all of your work and use a Punnett square).

The correct answer is - 50% or 1/2.

Explanation:

In codominance both alleles express their traits and blend to make new traits, there is no dominance or recessive pattern found. In this question, there is FF have pink feathers, PP has purple feathers and mottled diriclaws (FP). Then a cross between pink feathers and mottled diriclaws would produce offspring:
