Number of producer depends on ecosystem we are talking about. I am taking this question as terrestrial ecosystem so for the terrestrial ecosystem the answer will be group D.
In terrestrial ecosystem number of producer is higher than the second trophic level that is primary consumer. To study this we use pyramid of number. In most cases the pyramid of number is upright with members of successive higher trophic level being fewer than the previous one. The maximum number of individuals occurs at the producer level.
Answer:
1. Will not grow
2. will grow and will form new root
Explanation:
Meristematic tissue is the tissue formed by the undifferentiated cells which can form new tissues. The meristematic tissue present at the tip of root and shoot is known as apical meristem.
In the given question, if the apical meristem is removed from the shoot then the shoot from which the meristem will not grow and the shoot on which the meristem will be grafted will form the new shoot due to the ability of the meristematic cells to divide.
Thus, Will not grow and will grow and form new root are correct.
A molecule with polar and nonpolar parts that only partially dissolves in water is described as amphipathic.
Answer:
The process which must occur when intending to work with research animals that are covered by the U.S federal regulations is ethical review and approval
Explanation:
Some animals had been threatened of extinction due to inconsiderate usage and killings due to either commercial, food, or research purpose. The U.S government, therefore, to prevent the extinction of such animals, formulated a law to restrict the engagement of these animals, even in research if the research will involve the slaughtering, injuring, or alter the physiological functions of the subject animals. Therefore, there has been needing to undergo a compulsory ethical review process when planning to undertake research. This process will objectively review the aims and objectives of the intended research, the methodology involved in achieving the aim, as stated in the research proposal. The importance of this review is to determine if the research will have deleterious effects on the animals, both spontaneously and in the future.
