Answer:
The correct answer is - citric acid cycle.
Explanation:
In the third condition, fresh NADH molecules are not forming as NAD+ is getting accumulated fresh NADH molecules are continuously released or generated from the citric acid cycle.
There is no NADH production occurs which means there is some problem with citric acid cyle. Other conditions given is also the result of this inhibition occurs in the citric acid cycle that are decrease in proton gradient and ATP depeletion.
Answer: Stage M (Mitosis).
Explanation: The root tip is a meristem and this means that the root tip is responsible for the root growth. To do that, root tip cells divides actively to form root tissues, so that if we look an onion root tip under the microscope, the majority of cells will be in division, called mitosis, or Stage M of the cell cycle.
Answer:
The correct answer is: Yes.
Explanation:
- Conducting research on human subjects and specimens require the research organisation to obtain prior permission or consent from the person on whose specimen the research is being conducted.
- These ethical guidelines provided by the ethical committee need to be followed by all the research organisations and scientists.
- De-identification of biological specimen refers to the non-revelation of identity and preservation of the confidentiality of the person from whom the biological specimen is derived. The person from whom the biological specimen is obtained is made anonymous.
- According to the question, Investigator A obtained the biological specimen from human subjects for conducting research on emphysema.
- Under conditions of de-identification of the specimen, the specimen can be used by the Investigator B for performing research on lung cancer without the necessity for a re-consent.
Answer:
Homo species have differences in brachial index, face and teeth size as compared with australopithecines.
Explanation:
Australopithecines were found in pleistoocene era and adapted to the bipedal locomotion but shows differences in walking style as compared to early homo species. They have large brachial index. The postcanines were large but incisors and canines were small.
Early homo species were found around 2 million years ago. They shows bipedal locomotion with different walking styles. The brachial index of early homo species was small as compared with the australopithecines. The post canines were small but incisors and canines were large.
Herbivores are primary consumers.
