Answer:
option b is the right one
Answer:
Prometaphase
Explanation:
Prometaphase is the second phase of mitosis, the process that separates the duplicated genetic material carried in the nucleus of a parent cell into two identical daughter cells. During prometaphase, the physical barrier that encloses the nucleus, called the nuclear envelope, breaks down.
Answer:
The corect answer is c can be made by the animal"s body from other substances and is not readily absorbed by the gastrointestinal tract.
Explanation:
Accordings to our body"s demand there are 2 types of amino acids
1 Essential amino acids These amino acids are not synthesized in our body as a result we have to intake them through diet. Example phenylalanine ,methionine,threonine,valine.
2 Non Essential amino acids These amino acids are synthesized within our body as a result there is no requirement to intake them through diet and they are not readily absorbed by the gastrointestinal tract. Example Glycine, Alanine,Serine,Aspartic acid.
Answer:
Only options A (first one) 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.

The answer is C, speciation.
Let's say someone dropped 100 lions in the African savanna and 100 lions in the mountains. The mountain lions would evolve and adapt differently than the savanna lions.
The mountain lions might develop lighter fur for camouflage or larger lungs to get more oxygen from the thinner air, and the savanna lions might have to be a lot stealthier since there's no cover in the open plains.
