3 A butterfly has a wingspan of 62 mm. Charlie is asked to draw the butterfly with a magnification of x 5. What should the wings
vodka [1.7K]
Answer: 310mm
Explanation:
Since we are asked to calculate the magnification of X5 and are given a base value of 62 mm we can conclude that we must multiply our base value of 62 mm times five to get the new magnified wing span of 310 mm

This is a DNA mutation that does not result in a change to the amino acid sequence of a protein.
ohaa [14]

Answer: silence point

A silent point mutation may be an effect of a base-pair substitution (substitution of one base pair with another in DNA). However, silent point mutations are a special case where no amino acids are affected. As a result, since the monomers of proteins are amino acids, there is no change to the sequence of a protein.

Fully explain how cellular respiration is a chemical process whereby the bonds of food molecules and oxygen molecules are broken
Marianna [84]
Cellular respiration is a metabolic pathway that breaks down glucose and produces ATP. The stages of cellular respiration include glycolysis, pyruvate oxidation, the citric acid or Krebs cycle, and oxidative phosphorylation.

During cellular respiration, a glucose molecule is gradually broken down into carbon dioxide and water. Along the way, some ATP is produced directly in the reactions that transform glucose. Much more ATP, however, is produced later in a process called oxidative phosphorylation. Oxidative phosphorylation is powered by the movement of electrons through the electron transport chain, a series of proteins embedded in the inner membrane of the mitochondrion.
These electrons come originally from glucose and are shuttled to the electron transport chain when they gain electrons.


As electrons move down the chain, energy is released and used to pump protons out of the matrix, forming a gradient. Protons flow back into the matrix through an enzyme called ATP synthase, making ATP. At the end of the electron transport chain, oxygen accepts electrons and takes up protons to form water. Glycolysis can take place without oxygen in a process called fermentation. The other three stages of cellular respiration—pyruvate oxidation, the citric acid cycle, and oxidative phosphorylation—require oxygen in order to occur. Only oxidative phosphorylation uses oxygen directly, but the other two stages can't run without oxidative phosphorylation.).

Answer:

a.

c.

Explanation:

Lesch Nyhan syndrome is characterized by behavioral and neurological abnormalities, and excess uric acid production in the body. It occurs in males, almost exclusively.

Changes (mutations) in the HPRT1 gene causes Lesch Nyhan syndrome and is inherited in a recessive X-linked way. Several symptoms of Lesch Nyhan syndrome are Inflammatory arthritis (gout),  involuntary movements, self-injury and kidney stones.

Hence, the correct option are a. and c.
