X-rays are the radiation that allows us to see through the skin to visualize bones
<h2>Answer:</h2>
The three amino acid will be Tyrosine, Asparagine and Lysine respectively to sequence.
<h3>Explanation:</h3>
UTC GTU TTG
First the thymine in the sequence is changed to A, adenine because in the mRNA only three types of nucleotides are allowed which are Adenine, thymine and Uracil.
So the sequence will be:
UAC GAU AAG
These codons will be read by tRNA producing the polypeptide sequence of amino acids which are as follow:
Tyrosine Asparagine Lysine.
Answer:
B. A sperm cell
Explanation:
Meiosis creates gametes/sex cells, such as the sperm and egg.
So, sperm cells are formed by meiosis.
Meiosis doesn't create fertilized eggs, it instead creates normal egg cells.
Meiosis also doesn't create heart and bacterial cells because those are made in mitosis.
So, B is the correct answer.
Answer:
A polyp is a small clump of cells that form in the colon. Most of the time they are harmless but they could develop to be colon cancer which is the reason the polyp needed to be removed.
Explanation:
The surface area of a cell is approximated by the surface area of a sphere, given by the expression, 4πr². The volume of the spherical cell is given by the expression, 4πr³/3. The ratio between surface area and volume turn out to be, 1:r/3, or 3:r. This indicates that the SA/volume ratio is inversely related to the radius of the cell. Greater the radius, lower the ratio. Higher ratios are present in the prokaryotic cells This enables them to exchange food and water from their environment by the simple process of osmosis and diffusion. Eukaryotes have a larger cell radius and size. Thus, eukaryotes find it harder to exchange food and water by simple diffusion, rather they have specialised organelle present in the cell that actively transport food and water into the cell. These specialised organelles help the cell avoid the problem due to small SA/volume ratio.
