3 0

Explanation:

New ocean crust is formed at the mid ocean ridges. The new crust is then pushed away from the ridge as newer crust comes to the surface. The ocean crust then spreads out enlarging the ocean. The farer away from the ridge the ocean crust is the older the crust

Mrrafil [7]

Answer:

Explanation:

The production of ATPs for skeletal muscle contraction  depends on the conditions that the muscles are exposed to.

In presence of abundant oxygen, to the cells  Aerobic respiration-cellular respiration is the most ideal. 32 ATPs and 4 C02 are produced as by-products during the process as by products majorly two C02 from each  of the 2 acetyl Co A that enters the  kerb's cycle.

Likewise direct phosphoryaltion of ADP to ATP gives 32.0 kj/mol of heat liberated but no C02 was produced. This takes place during chemiosmosis. with 28ATPs produced.

In absence of oxygen, anaerobic respiration of skeletal muscles produced ATPs  from  glycolysis, heat and  2C<u>02 as products, but not as by-product</u>.Through alcoholic fermentation pathway.

Therefore ,the correct answer is Aerobic respiration, because it gives out C02 which is a by-product, released out of the body as waste from the lungs,and not use up  in  the body.

Generally speaking, which of the following mutations would most severely affect the protein coded for by a gene?a) a base substi
Pavlova-9 [17]

Answer:

Answer is C.

Explanation:

For A and B, a base substitution affects one of the three bases that comprise a codon, the DNA/RNA unit that corresponds to a particular amino acid. If one base is substituted, one codon and therefore one amino acid will be affected. Codons have built-in redundancy, so even by changing one base, the new codon sometimes still corresponds to the same amino acid. Therefore, a base substitution at most affects one amino acid, and sometimes doesn't affect it all.

Frameshift mutations cause a lot more trouble. These occur when you have a deletion or insertion that changes the number of bases in your gene. As a result, the "frame" of the codons changes (everything shifts one way or the other by the number of bases added/removed). This affects EVERY codon downstream of the mutation, so you can imagine that such a mutation would have a bigger effect the closer to the start of the gene it occurs. This is why C is correct.

The A159E mutation causes an A amino acid to be replaced with an E amino acid (their structures are shown here). What effects do
denis-greek [22]

Answer:

Due to hydrophilic nature of E amino acid, it will make it self to be exposed on protein surface and will disrupt the structure and potentially the function of troponin.

Explanation:

Since the E amino acid is hydrophilic, it will try to be exposed on the surface of the protein and thus will disrupt the tertiary structure and potentially the function of troponin.
