fenix001 [56]

Answer:

A) nutrient A only

Explanation:

In this case, enzyme A is required for the digestion of nutrient A, thereby evidencing that the mutation affects the enzymatic pathway and the mutant strain only can grow by supplementation with this nutrient. In molecular biology, mutant strains are useful to study enzymatic functions (for instance, the role of enzyme A in nutrient assimilation), as well as to examine downstream signaling pathways.

In experimental design, spontaneous mutations are induced to study their effects on the phenotype. Subsequently, reverse mutations may also be induced to reverse the forward mutation, thus restoring the original wild-type phenotype.

Where does nad+ deliver electrons compared to fad in cellular respiration?

Anna71 [15]

Answer:

The correct answer would be "NADH delivers its electrons to complex I and FADH₂ deliver its electrons to complex II" in cellular respiration.

There are mainly four complexes associated with electron transport chain of cellular respiration.

Complex I or NADH: ubiquinone oxidoreductase is the complex at which NADH is oxidized to form NAD⁺. The free electrons are transported with the help of ubiquinone.

Complex II or succinate dehydrogenase is the complex associated with oxidation of FADH₂ to FAD⁺. It also transports the free electrons with the help of the ubiquinone pool.

Complex III or cytochrome bc1 complex transport free electrons from ubiquinone to the cytochrome C which is a water-soluble electron carrier.

Complex IV or cytochrome c oxidase transport the free electrons to oxygen to form water.

What is one of the main causes of speciation?

belka [17]

I'm pretty sure it's <span>both. Allopatric speciation occurs when there is a physical barrier formed like a mountain or river. and Sympatric speciation occurs when there is a genetic barrier formed like a mutation that causes a different mating season or preference in mate choice.

hope this helps!</span>
