The correct answer for this question is (D) It can proceed in the dark.

Calvin cycle is named after Melvin C. Calvin, who won a Nobel prize in chemistry for finding it in 1961. Calvin cycle take place in chloroplasts during photosynthesis and it is a light-independent reaction so also called as dark reaction.

The Calvin cycle proceeds in three stages:

1. Carboxylation, during which CO2 combines with ribulose-1,5- bisphosphate

2. Reduction, during which carbohydrate is formed at the expense of photochemically made ATP and NADPH

3. Regeneration during which the CO2 acceptor ribulose-1,5- bisphosphate is formed again so that the cycle continues.

kumpel [21]

Answer:

The correct answer is D: "Apes have a Y-5 pattern of cusps, whereas Old World monkeys have a bilophodont pattern".

Explanation:

Apes and old world monkeys only have four kinds of teeth: two incisors, one canine, two premolars, and three molars. This dental formula is 2.1.2.3.

The old world monkeys characterize for having molars with four cusps joined by ridges. They have bilophodont teeth with better crushing, shearing and wearing capabilities than apes.

Apes´molars have 5 cusps, a Y-shaped space between those raised points, and no transverse lophs. These characteristics are known as the Y-5 pattern.

Can you guys help me with number 8. Plz plz plz

Oksanka [162]

RR x rr

or if you're using the letter "t" to represent the alleles TT x tt

Homozygous means that a particular gene has identical alleles on both chromosomes. TT is for a dominant (stronger) trait and tt is for a recessive (weaker) trait.

Hope this helps! :)

3c. explain what a codon is. include the words "nucleotides" and "amino acid" in your answer.

Harrizon [31]

Each combination of 3 nucleotides are called a codon. The codons then determine which amino acids are going to be inserted in the protein
