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 think 1 and 4 ? Sowwy if I’m wrong
Answer: it needs to go in through the s phase, moreover it needs to duplicate once the daughter cells are apart
Explanation:
Answer:
True. This process is called transduction.
Explanation:
When a virus infects a host, it incorporates its genetic material into the host cell and uses the host cell to replicate its own material. When the virus breaks out of the host cell i.e. lyses the host cell, the host's DNA is cut into bits. The virus can then incorporate (take in) part of the host’s DNA into its own.
When this virus attacks a new host, the foreign DNA it got from host 1 can now be introduced to the second host. This is possible because viruses inject their DNA (or RNA) into their host.
When the second host replicates, the new DNA introduced by the virus will also be replicated to its offspring.
This process is has been recorded in bacteria. Viruses that infect bacteria are called bacteriophage.
