the answer is a cuz DNA and ems are bacsily the something
Answer:
Sections of DNA are more similar in organism more closely related
Cytochrome c is used to provide evidence for evolution because most animals have this protein and is has undergone very little changes in these organisms such that more closely related species have the most similarity in amino acid sequence of cytochrome c
Explanation:
Cytochrome c is a protein found in mitochondria and is an important enzyme in cellular respiration. Cytochrome c is a highly conserved (have undergone very little changes) protein that in found in many different species of organismsmsuch as plants, animals, and many unicellular organisms. Cytochrome c is made up of about 104 amino acids linked together by peptide bonds. Being a small-sized molecule (molecular weight about 12,000 daltons) also makes it easier for evolutionary studies to be conducted on it.
Organisms that are most closely related have the most similarity in the amino acid sequence of the cytochrome c molecule. The amino acid sequences in cytochrome c molecule present in organisms is as a result of the information in their DNA.Thus, sections of DNA are more similar in more closely related organisms.
The hypothesis can be defined as an educated guess, which is made by the scientists doing a scientific research.
In this case, the scientist want to test the presence of the limonite in the yellow rocks, So, proposed hypothesis should include the color of rock they want to observe and the posssible outcome, which need to be tested.
So, a proposed hypothesis can be:
<h3>The rocks, which have yellow color are made up of mineral limonite. </h3>
Answer:
the capacity for or process of reacting to certain stimuli selectively when several occur simultaneously.
Answer:
The cell membranes are <u>Selectively permeable</u> or <u>semi-permeable.</u>
Explanation:
The cellular membrane allows the free passage of only a few substances while it blocks the pass of others.
Cellular membranes are <em>composed mostly of lipids arranged with their hydrophilic polar heads facing the exterior and the interior of the cells, while their hydrophobic tails are against each other</em>, constituting the internal part of the membrane.
Through this lipidic bilayer, some molecules can move from one side of the cell to the other. This free movement is called simple diffusion, and it depends on the substances' sizes and their concentration on each side of the membrane.
The membrane is selectively permeable because it only let small substances to move through it, with no protein mediating their passage.
