Dmitry_Shevchenko [17]

Answer:

α = 0 if β= 0

Explanation:

If both species want to persist in the same environment and their niches are also over lapping then both of the co-efficient values should be equal. There are two possibilities on these values for persistence. One is that one should compromise to the change produced by the invasive specie and two is that the new specie should compromise if he wants to stay (<em><u>Assuming that there is no competition</u></em>). In this way their niches won't overlap to a greater extent and therefore better chances of survival for both.

Can you determine which instances reflect a valid experiment or conclusion? Check only those that are valid.
vagabundo [1.1K]

Answer:

Only options a reflects the instances with valid experiment or conclusion.

Quality of any experiment depends upon two things reliability and validity. Reliability is measure of regeneration of results every time an experiment is performed under specific conditions.

Validity is measure of accuracy of results of an experiment. It can be check by two ways: internal validity (checks the design of the experiment) and external validity (checks if the conclusion is the real explanation of the phenomenon).

Now, in marine biologist experiment, he concluded the results only after one breeding season. This makes his results unreliable as it might have happened by chance.

Similarly, in cola experiment the taste was only checked by one candidate i.e. Karl. He might have problem in his taste buds. In addition, the temperature of cola can also affects its taste which is not taken care of in the experiment. Hence, it is not the valid experiment.

Similarly. Jeanette could use more plants for her experiment and Robert just followed only one instruction. He didn't perform any experiment.

DerKrebs [107]

Answer:

Its primary role in red blood cells is to maintain levels of red blood cells with low levels of this compound are more suceptible to oxidative damage.

Explanation:

Pentose phosphte pathway helps in the formation of reducing equivalent named NADPH.

  The so formed NADPH is used to maintain a normal cellular level of glutathione which act as antioxidant.

 As glutathione is not mantained in its normal level, it ability to reduce to adverse effect of hydrogen peroxide is cut down.

  As a result cell is more suceptible to oxidative damage.
