The correct answer is:

Meiotic prophase I

Explanation:

The cause that it is Prophase 1 is that the stage shows the chromosomes spanning close to cross over genetic information before they are solidified into the center of the cell to split, which is the stage of Metaphase 1.Synapses just shows that homologous pairs connecting with each other. This could only suggest that they are crossing over which issues in Prophase 1. Also, in Prophase II when the cell has beforehand divided it would no longer be in tetrad form. Metaphase is when the homologous pairs get pulled aside.

You have begun work on a new experiment determining exactly how certain neurotoxins affect the nervous system. After running mul
Lynna [10]

When looking at a Neuromuscular Junction (NMJ), we know that neurotransmitters (NT) are released from the presynaptic cell and they then bind to the receptors that are located on the postsynaptic cell - this causes the effect of the NT being released.

So we are told that NT are still being released, however they are not having an effect. This would mean that they are probably being blocked by something - in this case, it seems that the neurotoxin is the culprit in the blocking of these receptors.

Therefore, if the NT cannot bind to the receptors on the postsynaptic cell, they are not going to have any effect, no matter how much NT is being released.

So the answer in this case is: The neurotoxin is most likely C) Blocking the receptors on the postsynaptic cell.

Which of the following statements about carotenoids is NOT true? Carotenoids include red, orange, and yellow pigments. Carotenoi
kvv77 [185]

       The right answer to this question is option D. Carotenoids are categorized into two major divisions: carotenes and beta carotenes

       First, let's check option A, it says that the carotenoids include red, orange and yellow pigments, that's true, we can check that on lab for example, a vegetable that can be mentioned here are carrots, it has lots of this and it's very healthy too, and remember, there isn't a single animal that can produce carotenoids, so they need to grab it from nature.

       The second option, B. says that sometimes carotenoids are sometimes called as acessory pigments, that's true too, some studies consider them acessory pigments, so, they're not alone there, there are different kinds of pigments that can be on that plant, and they're also very important for the animals. Option C refers to beta carotene as the most abundant carotene in plants, that's true too, we can also find other kinds of carotenoids on plants, but this one as it's seen in lab, is the most common one. The last one, D, isn't true, the two major divisions are: Xanthophylls and Carotenoids, beta carotenoids are a type of carotenoids, not a different group.
