What are some ways you think scientists can affect or utilize the genes of organisms?

Answers

Answer:

I'm not quite sure what your looking for

Explanation: scientists can take the genes of one successful crop, animal, etc, and insert that gene into future things so all offspring will be successful. This is called genetically modifying. Another thing scientists can utilize genes for is cloning. There have been ideals of the perfect human for many years and now scientists are trying to alter these genes to have perfect offspring according to your standards.

A man and a woman have a child together. The mother's blood type is type O and the child's blood type is type A What could the father's genotype be?

Answers

Answer:

iAiA or iAi = Type A

Explanation:

Blood group in humans is controlled by a gene with multiple alleles. The alleles iA and iB are co-dominant over one another but dominant over allele i. In the blood type:

iAiA or iAi - type A

iBiB or iBi - type B

iAiB - type AB

ii - type O

According to this question, a man and a woman have a child together. The mother's blood type is type O (ii) and the child's blood type is type A (iAi). This means that the father's blood type must be a type A with genotype "iAiA or iAi".

A father sheep has curly wool while a mother sheep has straight wool. Which of these statements explains why one of their baby lambs has curly wool?

Answers

Answer:

This means that the baby sheep received the same set of genes as the father sheep giving it curly wool.

Explanation:

This means that the baby sheep received the same set of genes as the father sheep giving it curly wool.

OR if the baby sheep received a mixed set of genes , one from father , the other from mother , the gene of the father is dominant over the gene of the mother and it has given the baby sheep curly wool.

During fertilization the baby must have received the same set of genes as those of its father. If the baby has received a mixed set of genes then the genes of the father are dominant over the genes of the mother resulting in curly wool.

The fathers gene may be dominant due to environmental circumstances or other factors.

Answer:

Explanation:The baby lamb inherited its copies of the gene for wool shape from its father and not from its mother. Just like its father’s genes, those genes instruct for proteins that connect in ways that make its wool curly.

state and explain components of blood

Answers

Answer:

It has four main components: plasma, red blood cells, white blood cells, and platelets. Blood has many different functions, including transporting oxygen and nutrients to the lungs and tissues

Explanation:

Plasma is the main component of blood and consists mostly of water, with proteins, ions, nutrients, and wastes mixed in. Red blood cells are responsible for carrying oxygen and carbon dioxide. Platelets are responsible for blood clotting. White blood cells are part of the immune system and function in immune response.

Photoperiodism is one example of how a plant responds to changing seasonal conditions. Why is it important for plants to be able to respond to seasonal changes?

Answers

Answer:

It is important because plants respond to light depend, logically enough, on the plant's ability to sense light. Phototropism is a directional response that allows plants to grow towards, or in some cases away from, a source of light. Photoperiodism is the regulation of physiology or development in response to day length.

Which section of the article BEST explains why the development of CRISPR-Cas9 is significant for the scientific community?

Answers

Answer:

It allows the scientists to activate gene expression instead of cutting the DNA.

Explanation:

The development of CRISPR-Cas9 is significant for the scientific community because this development allows the scientists to activate gene expression instead of cutting the DNA. This technique allows the scientists and researchers to study the function of the gene. Before development, Cas9 enzymes produced by the CRISPR system binds to the DNA and cuts it by shutting the targeted gene off so this development of CRISPR-Cas9 enables the scientists to activate gene expression instead of cutting the DNA.

How is information for a specific protein carried on the DNA molecule?
a. as a sequence of nucleotides
b. in the double helix shape of the condensed chromosome
c. in the ratio of adenines to thymines
d. as a pattern of phosphates and sugars

Answers

Answer:

Explanation:

Genetic information is carried in the linear sequence of nucleotides in DNA. Each molecule of DNA is a double helix formed from two complementary strands of nucleotides held together by hydrogen bonds between G-C and A-T base pairs. ... In eucaryotes, DNA is contained in the cell nucleus.

The information for a specific protein is being carried on the DNA molecule as a sequence of nucleotides. Hence, option (a) is the correct answer.

Nucleic acids are of two types. They are namely deoxyribonucleic acid (DNA) and ribonucleic acid (RNA). DNA molecule carries the information for a specific protein. They are described as follows:

DNA is the genetic material of the cell DNA molecules undergo a process called transcription to code for codons on mRNA strand These codons tend to pair with tRNA molecule which holds the amino acids The amino acids will then form a chain in the sequence of DNA nucleotides to result in protein formation

Thus, we can conclude that the information for a specific protein is being carried on the DNA molecule as a sequence of nucleotides. Thus, option (a) is the correct answer.

Which conclusion is supported by the fact that the black-breed boar, with its quality meat, and the white-breed sow, with its quality fertility, are swine that are often matched for mating? Animals are often paired based on physical traits and personal compatibility. Strong reproductive capability is the most important trait in animal breeding. Selective breeding combines ideal traits of animals to replicate in offspring. Swine are the only agricultural animal species that are currently crossbred.

Answers

Answer:

Selective breeding combines ideal traits of animals to replicate in offspring

Explanation:

Selective breeding is the process which involves choosing parents with particular characteristics to breed together and produce offspring with more desirable characteristics. It is also known as artificial breeding and provides both plants and animals with greater variation and higher chances of survival. Selective breeding can be used to produce plants with bigger and tastier fruits and vegetables, crops with greater resistance to pests and diseases, and bigger animals that can be used for meat or milk production. The process of selective breeding is of great importance to the farmer today as it has brought about greater economic advantages.

In the instance of the black-breed boar and the white-breed sow being matched for mating, the reason is to combine these desirable traits in their offspring. The black-breed boar produces quality meat while the white-breed sow has quality fertility. Mating between these two breeds will produce offspring which has both traits of quality meat production as well as quality fertility.

mutations in dna may or may not result in a change in the phenotype of an organism. in which of the following situations will a mutation appear in the phenotype of an individual

Answers

Some mutations don't have any noticeable effect on the phenotype of an organism. This can happen in many situations: perhaps the mutation occurs in a stretch of DNA with no function, or perhaps the mutation occurs in a protein-coding region, but ends up not affecting the amino acid sequence of the protein

The type of mutation which may not result in any chage to the penotype of an organsim is called a silent mutation.
