Answer:
a.) ventilation, circulation, cellular respiration
Explanation:
a.) ventilation, circulation, cellular respiration
b.) diffusion in tissues, cellular respiration, diffusion at respiratory surface
c.) ventilation, diffusion in tissues, circulation
d.) circulation, cellular respiration, diffusion in tissues
e.) circulation, ventilation, cellular respiration
Ventilation occurs in the lungs and is the process by which carbon dioxide in the capillaries is lost to the environment while oxygen is taken in. Circulation is the process by which this dissolved oxygen is taken by the blood to tissues around the body. When this oxygen is taken to tissue, the concentration gradient allows the oxygen to be taken up by tissue. This oxygen is used as an electron acceptor (when it reduced to water) in the mitochondria during electron transport chain of cellular respiration.
This would cause the overpopulation in the grassland preserve. There would be too many antelopes and zebras that they would have to compete for survival. The food resources would run out for both species and cause a competition among every animal.
Answer:
D.Most bilaterians have tissues but some do not.
Explanation:
Answer:
DNA do not normally cross the nuclear membrane.
Explanation:
DNA (Deoxyribonucleic acid) is present in the nucleus which contains the genetic information of an organism. Nucleus is necessary for whole the process of cell division and initiation. During cell division DNA plays a most important role carrying of genetic information of old cell to the newly synthesized cells, which only occurs during cell division.
All processes like replication and transcription needs enzymes which are normally found in the nucleus. So, for the protection of DNA keeping DNA within the nucleus and do not cross the nuclear membrane. If DNA is floating in the cytoplasm than DNA can not be transcribed its information into RNA and this process is known as transcription process (DNA into RNA).
