A woman without hemophilia marries a man with hemophilia they have a daughter with hemophilia what is the genotype of the mother and father

Answers

Answer:

Mother- XXH

Father- XHY

Explanation:

The mother is a carrier for hemophilia and since the disease is sex linked and found on the X chromosome, only one of the alleles has that H allele attached to it. The father is male so he only has one X chromosome, which is why he is effected by the disease and not just a carrier like the mother.

Which person would be most likely to own a pet, and why?


an animal welfare proponent, because pets are not being used for food or work

an animal welfare proponent, because she believes people have a right to own and dominate animals

an animal rights proponent, because she believes pets should treated equally to humans

an animal rights proponent, because she believes in caring for all animals.

Answers

Answer: it’s D

Explanation: I just got it right

Animal welfare is a pro-ownership philosophy, whereas animal rights activists believe that humans shouldn't own animals, hence option C is correct.

What are animal rights?

Animal welfare means ensuring that all animals used by humans have their basic needs in terms of food, shelter, and health met, as well as that they experience no unnecessary suffering in providing for human needs.

Animal rights relate to the idea that animals have rights that go beyond human wants and requirements. Supporters of animal welfare think that people can utilize animals for food, companionship, clothing, entertainment, experimentation, and other purposes.

As a result, some who support animal rights believe that humans should not eat animals.

Therefore, over the past ten years, there has been a sharp increase in the number of animal rights activists that support their rights, hence option C is correct.

A response is a “reply” or a “reaction.” Use this information to explain why the health damage that results after exposure to a harmful chemical is called a response.

Answers

a response to exposure would mean that your body is reacting to the harmful chemical. when your health is at stake, your body reacts with a response. for example, if you get a chemical in your eye, you start tearing up and your eye turns red. that's a response to the chemical.

A chemical substance is a stimulus which produces a response or reply in the body.

What is a stimulus?

A stimulus is a factor or agent that produces a response in the body of a living organism.

When a stimulus is received by the body, it produces a response.

A harmful chemical that is introduced to the body is a stimulus which could cause damage to the body.

Therefore, a chemical substance is a stimulus which produces a response or reply in the body.

How does the double helix structure of DNA explain how the molecules can be copied or replicated

Answers

Answer:

How does the double-helical structure of DNA explain how the molecules can be copied or replicated? Because of base pairing, each strand has all the information to serve as a template for the other strand.  DNA replication occurs only during the S phase of the cell cycle.

Explanation:

Because of base pairing, each strand has all the information to serve as a template for the other strand.  DNA replication occurs only during the S phase of the cell cycle.

What is DNA?

Humans and nearly all other species carry their genetic information in DNA, also known as deoxyribonucleic acid. The DNA of an individual can be found in almost all of their cells.

The majority of DNA is found in the cell nucleus (where it is known as nuclear DNA), but there is also a tiny quantity of DNA in the mitochondria (where it is called mitochondrial DNA or mtDNA). Cellular organelles called mitochondria transform the energy from food into a form that can be utilized by cells.

Adenine (A), guanine (G), cytosine (C), and thymine (C) are the four chemical bases that make up the code that stores the information in DNA (T).

Therefore, Because of base pairing, each strand has all the information to serve as a template for the other strand.  DNA replication occurs only during the S phase of the cell cycle.

24. Fill in the blanks. An enzyme is made up of _____. Enzymes can
break down proteins into
_____.​

Answers

enzymes are made of strings of amino acids chemically bonded to one another. These bonds give each enzyme a unique structure, which determines its function. They mostly break down carbohydrates and fats. Once a protein source reaches your stomach, hydrochloric acid and enzymes called proteases break it down into smaller chains of amino acids. Amino acids are joined together by peptides, which are broken by proteases.

Reactions between atoms occur when:

A :an atom seeks to fill its outer shell of electrons
B :an atom seeks to balance its positive and negative charges
C :the reaction will result in paired electrons

Answers

Answer:

A :an atom seeks to fill its outer shell of electrons

Explanation:

Reactions between atoms occur due the desire of an atom to fill their outer shell electrons.

The driving force for many interatomic bonding is the tendency to have completely filled outer energy levels like those of the noble gases.

The various interatomic interaction which leads to chemical reaction is in a bid for the atoms to be isoelectronic in the outer energy level with the noble gases. This is achieved by gaining, losing or sharing of electrons.
