Why are dead or weakened viruses used instead of normal viruses to create a vaccine?

Answers

Answer 1
I think its because vaccines are just to help your body learn how to fight off the virus, it’s not to actually give you the virus. Hope this helped!
Answer 2

because dead viruses aren't as effective as dead than "alive"

How does gene expression differ between human fibroblasts and induced pluripotent stem cells (iPS)?

Answers

Answer:

Both have different gene expression due to produce from different sources.

Explanation:

Gene expression is different between human fibroblasts and induced pluripotent stem cells because both cells are formed from different sources. Human fibroblasts is produced from ''mesenchyme'' a type of connective tissue whereas induced pluripotent are the stem cells which can be produced from adult cells so we can say that both have different gene expression.

Both have different gene expression due to produce from different sources.

The following information should be considered:

Gene expression is different between human fibroblasts and induced pluripotent stem cells since both cells are created from different sources. Human fibroblasts is generated from ''mesenchyme'' a type of connective tissue while on the other hand,  induced pluripotent are the stem cells that could be generated from adult cell.

Do mutations in body cells contribute to genetic variation?(1 point)

A) No, the causes of body cell mutations are outside the body and cannot alter DNA.

B) Yes, the mutations can be passed on to offspring and contribute to variation in the population.

C) Yes, these body cell mutations lead to mutations in the gametes.

D) No, the mutations cannot be passed to offspring and only affect the individual.

Answers

A mutation is the alteration of the genetic sequence of an organism, which can either be inherited or cannot be inherited. The mutation when transmitted to the offspring leads to genetic variation.

The correct answer is:

Option B. Yes, the mutations can be passed on to offspring and contribute to variation in the population.

Mutation is the change in the genetic sequence of the organism, which can be caused due to environmental factors and can be inherited.

The mutations can lead to genetic disorders, chromosomal disorders, or any other conditions. The mutations like a disease or adaptation that can be passed onto the offspring can result in genetic variation.

The mutation leads to genetic diversity, as the mutation is also the first step towards evolution. The organisms better suited to the environment will survive more and adapt more. These changes in the organisms will be inherited by the offspring leading to genetic variation.

Therefore Option B is correct.

The leaves of plants have many specialized structures. Which statement explains the importance of the stomata and guard cells for the plant?
o They protect the plant from pests
o They are involved in plant reproduction
They work together to regulate water loss and gas exchange.
o They regulate the amount of water that enters the plant for cellular respiration

Answers

Answer:

They work together to regulate water loss and gas exchange.

They work together to regulate the loss of water and exchange of gases.

Stomata and guard cells

The tiny pores or openings in plant tissue, which allow for the exchange of gases are known as stomata.

The unique cells, which surround stomata and work to close and open the stomatal pores are known as guard cells.

Both these helps a plant to take in carbon dioxide at the time of photosynthesis and also assist in reducing the loss of water by getting closed when conditions are dry and hot.

Thus, stomata and guard cells work together to regulate the loss of water and gas exchange.

Curly hair (C) is dominant where straight hair (c) is recessive. If a person who is CC were to have children with a person who is cc, could it be possible for them to have a child with straight hair?

a
yes
b
no

Answers

Answer:

No, it would not be possible to have a child with straight hair.

Explanation:

The Punnett cross would be CC x cc, so all the offspring would be Cc. Since straight hair is only cc, the kids would not have straight hair.

Awnser:

yes, it is possible :)

Explanation:

Their children would would have the dominant trait, curly hair, and the recessive straight hair gene hidden in their dna. If there was a chance that one of their curly haired children met with a cc-partner with straight hair, then they would have a 1 in 2 chance. Even with a Cc-partner, there would be a 1 in 4 chance of the straight hair trait "skipping a generation".
