LiRa [457]

Answer:

b. allele

Explanation:

An allele is a variant form of a gene. In this problem, there is one gene (that determines seed color) with two possible alleles (green and yellow).

<u>The other options are wrong because:</u>

The genotype is the combination of alleles an individual has.

The karyotype is an individual's collection of chromosomes, paired and ordered.

A homozygote individual has the same alleles for a particular gene.

A heterozygote individual has different alleles for a particular gene.

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.

Answer:

Carbohydrates - monosaccharides

Proteins - amino acids

Nucleic acids - nucleotides

Lipids - fatty acids (hydrocarbon chains)

Explanation:

There are four major biological molecules called biomolecules in nature namely; carbohydrates, proteins, nucleic acids and lipids. These four molecules form the bedrock upon which life is built. The biomolecules mentioned above are POLYMERS formed as a result of the combination of two or more simpler molecules called MONOMERS in a process called CONDENSATION.

The monomer of each polymeric biomolecule is as follows;

Carbohydrates - monosaccharides

Proteins - amino acids

Nucleic acids - nucleotides

Lipids - fatty acids (hydrocarbon chains)
