Answer:
A. A water molecule passes through a semi permeable membrane
Explanation:
Facilitated diffusion is the diffusion of a molecule without any assistance from a protein or protein channel.
In facilitated diffusion, a molecule will diffuse by itself through a semi permeable membrane, such as the cell membrane.
Answer choices B, C, and D are incorrect because they are all examples of facilitated diffusion. The molecules required assistance from a protein.
Answer choice A is correct because the water molecule was able to pass through by itself.
So, the correct answer is A. A water molecule passes through a semi permeable membrane
Answer:
particulate hypothesis of inheritance
Explanation:
This states that the inheritable factors retain their identity generation after generation.
An organism produced by asexual reproduction would more closely resemble its parent because an organism produced through asexual reproduction is created by the parent duplicating its genetic code and separating into two. Essentially the child is a duplicate.
Retroviruses also have the enzyme reverse transcriptase, which allows it to copy RNA into DNA and use that DNA "copy" to infect human, or host, cells.
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). More than 99 percent of the 3 billion bases that make up human DNA are the same in every person.
