Answer:
B. eats more than just frogs
Explanation:
A food web is more realistic because a snake <u>eats more than just frogs</u>
Out of the following given choices;
a) The amount of oxygen produced
b) The rate of ATP synthesis by ATP synthase in the chloroplast
c) The rate at which NADPH is produced
d) The rate at which the protons are transported into the thylakoid
The answer is; A
The photosystem captures energy from sunlight and uses it to split a water molecule. After splitting the water molecule (by taking an electron), the protein complex transports the electron to plastoquinone. The splitting of water molecules results in evolving of oxygen molecules. The hydrogen is what is used to reduce carbon dioxide to glucose.
Answer:
Genes coding for proteins involved in chiasma formation.
Explanation:
Chiasma is the connecting link between two non sister chromatids from homologous chromosomes. At chiasma chromosomal crossover takes place in which the genetic material is exchanged between the chromatids. During meiosis aneuploidy occurs if chiasma is absent or impaired due to a mutation in genes encoding for proteins involved in chiasma formation.
Aneuploidy is characterised by presence of abnormal number of chromosomes in cells. They can be 45 or 47 in number apart from the usual 46. Due to impaired chiasma, chromosome pair fails to separate and is passed on to the egg or sperm as it is hence there is one gamete with an extra chromosome and one gamete with a less chromosome. Aneuploidy can result in many genetic disorders like three copies of chromosome 21 can result in Down syndrome.
