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

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

Answer:
The answer is A.
Explanation:
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
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.Which is true of hydrolysis reactions?
