Answer:
The answer is D.
Explanation:
It occurs continuously in the cells of all organisms and often involves an exchange of gases. There are 2 types of cells, 1 is Eukaryotic, which holds a nucleus, and the 2nd is Prokaryotic, which do not. Prokaryotes are single-celled organisms.
Answer:
a. two plant species flowering at different times.
Explanation:
<em>The only option that is not a post-zygotic reproductive isolation mechanism would be option a, when two plant species flower at different times.</em>
Post-zygotic reproductive isolation mechanisms are those mechanisms that act to ensure that the product of fertilization remains invalid. This is as opposed to pre-zygotic isolation mechanisms that act to prevent fertilization and hence, formation of zygotes.
In option b, c, d and e; the zygote has been formed already and all the forces are just acting to ensure that it remains invalid. whereas in option a, there is no fertilization yet.
<u>Two plant species flowering at different times will ensure that there is no cross pollination between the two species. Without pollination, there cannot be a zygote formation.</u>
Hence, the correct option is a.
Answer:
A) Neither; they both have the same frequency.
<u>Answer:</u>
<em>The process of cellular respiration begins with </em><u><em>molecules of glucose and ends with production of energy.
</em></u>
<u>Explanation:</u>
<em>Cellular respiration is the process that takes place inside living cells and the initial process is glycolysis.</em> The process of glycolysis breaks down the glucose molecules which contain 6 carbon atoms each into two three-carbon pyruvate molecules.
The output of cellular respiration is energy. The energy produced in cellular respiration is in the form of ATP. <em>Respiration is an exothermic process and two ATPs are produced as a result of cellular respiration. </em>
