A chromosome is a piece of protein that is inside a cell's Nucleus that contains genetic information. DNA is inside the chromosome, which gives the chromosome the genetic information
Answer:
The correct answer is b. All round seeds
Explanation:
If an RR plant is crossed with an rr plant than all the phenotype will produce round seed and the frequency of the Round seed plant to wrinkled seed plant would be 4:0.
R R
r Rr Rr
r Rr Rr
So all the phenotypes will be heterozygous dominant for the round seed which means that all phenotypes will have a single dominant allele for round seed which is enough to express round seeds in the phenotypes.
Answer: Exergonic reaction; Endergonic reaction
In coupled reactions, the energy released by an exergonic reaction is used to drive an endergonic reaction. ATP breakdown is often coupled to cellular reactions that require an input of energy.
Explanation:
Cellular reactions include Exergonic and endergonic reactions. An exergonic reaction is one that occurs spontaneously and brings about the release of energy (in form of ATP). On the other hand, an endergonic reaction proceeds only with the input of energy.
Thus, exergonic reactions are usually coupled to endergonic reactions
Answer: a. cervical enlargement.
Explanation:
Cervical enlargement corresponds to the enlargement of the spinal cord. The spinal cord is the origin of the spinal nerves that contribute to an important task of supplying blood to the upper limbs.
The cervical enlargement results in an increase in the volume of the motor cells in the ventral part inside the grey matter. The motor neurons which are sited posteriorly supply to the upper limbs. Those which supply to the distal muscles are situated further posteriorly.
