Since cell division occurs twice during meiosis, one starting cell can produce four gametes (eggs or sperm). In each round of division, cells go through four stages: prophase, metaphase, anaphase, and telophase.
Answer:
Consider a marcomolecule an molecule containing multiple assets, including proteins and other vital assets to an individual atom.
Answer:
Translation
Explanation:
This process occurs in the ribosomes. As the ribosome reads the codons on the mRNA the corresponding tRNA with the complementary anticodon is recruited. The tRNA brings in an amino acid (attached to it), and the amino acid is joined to the rest of the growing polypeptide chain. Each codon/anticodon specifies for a specific amino acid.
Answer:
a. both oxygen and carbon dioxide
b. carbon dioxide only
c. carbon dioxide only
d. oxygen only
e. carbon dioxide only
f. oxygen only
g. oxygen only
h. oxygen only
Explanation:
This question is describing the gaseous exchange of carbon dioxide and oxygen that occurs during cellular respiration. The gaseous exchange occurs via a structure called ALVEOLI OR AIR SAC.
According to this question, the following statements in the question will be matched with whether it applies to oxygen only, carbon dioxide only, or both oxygen and carbon dioxide:
a. Both oxygen and carbon dioxide are diffused through the alveoli capillaries.
b. Carbon dioxide is the waste product of cellular respiration (excreted via the lungs).
c. Carbon dioxide have the ability to form carbonates (CO3²-) and are sometimes transported in that form.
d. Oxygen from the lungs diffuse into the alveoli during inhalation.
e. Carbon dioxide from the body tissues are carried by the blood into the alveoli in order to be transported out of the body.
f. Inhalation is the taking in of air (oxygen-containing). Hence, oxygen only enters alveoli during inhalation.
g. Oxygen is the necessary substance needed by cells in order to perform cellular respiration (aerobic).
h. Haemoglobin is an iron-based protein present in the blood cells. It possess affinity for oxygen and carries oxygen in the blood.
I believe the correct answer from the choices listed above is option C. If the number of hydrogen ions being pumped into the thylakoid is rapidly decreasing, then less sunlight is being used by photosystem II. Hope this answers the question.
