Milk is converted to yogurt under certain conditions when the microorganisms in the milk produce acid. Which of these processes
oee [108]

Milk is converted to yogurt under certain conditions when the microorganisms in the milk produce acid. Which of these processes would you expect to be key in the production of yogurt?

a. Photosynthesis

b. Lactic acid fermentation

c. Krebs cycle

d. Alcoholic fermentation

Answer:

b. Lactic acid fermentation

Explanation:

Lactic acid fermentation occurs when pyruvate formed by glycolysis is reduced into lactate under the anaerobic conditions. The NADH serves as an electron donor for the reduction of pyruvate into lactic acid. Lactic acid bacteria are the anaerobic bacteria that ferment the milk sugar lactose into lactic acid. This converts the milk into yogurt. <em>Lactobacillus, Streptococcus salivarius</em>, etc. are mostly responsible for the conversion of milk into yogurt.

What type of chlorophyll does the reaction center contain
LuckyWell [14K]

Answer:

Chlorophyll "a"

Explanation:

The reaction centers of the photosystem have chlorophyll "a" molecules. The chlorophyll "a" that functions as a reaction center for the photosystem II has absorption maxima at 680 nm and therefore, it is called P680. The reaction center of photosystem I also have chlorophyll "a" molecules that have the absorption peak at 700 nm. The chlorophyll "a" molecules serving as reaction centers transfer the photoexcited electrons to a primary acceptor during the light-dependent phase of photosynthesis.

A trait I which the alleles are not dominant over one another
JulsSmile [24]

Answer:

They are co-dominance and incomplete dominance.

<h2 />

Explanation:

Co-dominance occurs when both alleles in a heterozygous genotype for a trait are both equally expressed. An example is the human AB blood group, in which both the A and B alleles are equally expressed.

Incomplete dominance occurs when the heterozygous genotype for a trait is expressed as a blend. An example is blue feather color in chickens, in which a black allele and white allele together are expressed as blue feather color.
