1 answer:

Some of the light energy is converted to chemical energy. During this process, a phosphate is added to a molecule to cause the formation of ATP. ... The ATP then provides energy to some of the other photosynthetic reactions that are causing the conversion of CO2 into sugars. During photosynthesis, energy from sunlight is captured and used to produce sugar molecules.

Explanation:

Gamete formation involves the random and independent segregation of alleles. During anaphase 1 (meiosis), occurs the independent separation of homologous chromosomes that migrate to opposite poles of the cell. This separation generates different chromosomal combinations in the daughter cells. There are two alternatives per homologous pair.

The number of gametes with different combinations is 2ⁿ, where

n = number of homologous pairs.

In the exposed example there are 4 pairs of chromosomes, so

the number of possible combinations of chromosomes = 2ⁿ = 2⁴ = 16

Individual: AaBbCcDdEe

You can make use of the fork line method to easily figure out the possible gametes.

What kind of scientist would use a dichotomous key?

Vadim26 [7]

Answer:

Many scientists use dichotomous keys to identify plants, animals, and other organisms. They may also use dichotomous keys to identify species, or to determine whether a particular organism has been identified and described before. However, dichotomous keys are not used only to identify organisms.

What is the relationship between the TRIPLET CODE and the CODON ??

Zigmanuir [339]

Answer:

each nucleotide triplet (called a codon) specifies a particular amino acid. Thus, a nucleotide sequence in the DNA specifies a protein provided that a messenger RNA molecule is produced from that DNA sequence. Each region of the DNA sequence specifying a protein in this way is called a gene.
