Answer:
c. bivalents.
Explanation:
In Meiosis a bivalents are formed during the first stage of meiosis which is the prophase. The bivalent consist of a paired chromosome and four chromatids i.e two chromosomes in a tetrad. one chromosome comes from each parent.
In mitosis, a bivalent is not formed. There is the presence of chromatids, homologs, centromeres and spindles during mitosis and meiosis.
Answer:
Anabolism collectively refers to all the processes of chemical reactions that build larger molecules out of smaller molecules or atoms; these processes are also known as anabolic processes or anabolic pathways. Anabolic pathways use energy, while catabolic pathways release energy.

Answer:
The ANS ( Autonomous nervous system) is divided to PNS (parasympathetic nervous system) and SNS (sympathetic nervous system).
Explanation:
The PNS maintains homeostasis and digestive response. The SNS involves fight and flight response. The SNS releases adrenaline. PNS do not involve any secretion of adrenal gland. The PNS relaxes the muscular system, The SNS allows muscles contraction. The PNS decreases heart rate. The SNS increases heart rate.
What is true of chemical energy is that chemical energy can be stored more efficiently as glucose than it can be as ATP. All the other answers in this case don't really apply. The correct answer is therefore A.
When ATP is broken down to ADP we get a release of energy - B and C are therefore wrong. Energy is broken in more ways as only ADP - D is also wrong. Only A stays as the correct answer.
