Answer:
Ducks have no preference for white or wheat bread
Explanation:
The null hypothesis is the statement of no change (default). It proposes no relationship between the variables of the phenomenon under investigation. This hypothesis is usually considered to be true until proven otherwise by the experiment. It is designated as H0 and, if proven wrong, the alternative hypothesis (HA), is adopted.
Answer:
M phase
Explanation:
While there are many checkpoints within the cell cycle, the specific checkpoint you are referring to most likely takes place in the M (mitosis) phase.
Before the M phase (which includes the G1, S, and G2 phases), the cell grows, the number of organelles increases, and DNA replicates. After the G2 phase, the M phase begins. At the beginning of this phase, the DNA condenses, lines up in the center of the cell, attaches to spindle fibers, and is pulled to opposite ends of the cell. If this checkpoint receives the proper signal, the actual division of the cell will occur.

The forensic anthropologists
learn that "Grave 15"
contained the remains of numerous women and children from the Guatemalan
massacre during the height of Guatemala’s civil war. Due to their clothing and
jewelry, their ancestry was traced and that they came from Río Negro. The
forensic team uses DNA to identify each skeleton and return them to their
families.
Answer:
The correct answer is option a.
Explanation:
Yes, the light reactions also depend upon the Calvin cycle. Calvin cycle refers to a phenomenon that is used by the plants and algae to convert carbon dioxide from the atmosphere into sugar, the food needed by the autotrophs in order to grow. The plants rely upon the Calvin cycle for food and energy.
In the given case, the rate of oxygen production would get diminish as the rate of ATP and NADP+ generated by the Calvin cycle diminishes. Of all the outcomes of the Calvin cycle, ADP and NADP+ are the only ones that get utilized by light reactions.
The ADP and NADP+ are used up by the light reactions to fuel their reactions. This illustrates that if the rate of ADP and NADP+ generated by the Calvin cycle diminishes the production of oxygen by the light reactions also diminishes.
