Examination of your slide will show that a few nuclei do not appear next to a cell wall

Answers

Answer 1
Answer:

Hello. This question is incomplete. The full question is:

"Examination of slide will show that a few nuclei do not appear next to a cell wall in onion cell. Could you explain that observation?"

Answer:

You are visualizing the onion cell during mitosis interphase. At that time, cells may have multiple nuclei and some of them may not be visible near the cell wall.

Explanation:

Experiments with onion roots are common when we want to visualize the phases of the cell cycle or to visualize chromosomes and cell nuclei.

If after the experiment with an onion cell you are unable to visualize the cell nuclei near the cell wall, it means that you are visualizing the cells during the interphase of mitosis. At that time, cells may have multiple nuclei and some of them may not be seen near the cell wall.
Answer 2
Answer:

The onion root tips are very famous for observing the distinct phases of mitosis as the chromosomes are very large and get very dark when stained.  

The epidermal cells in the onion take place cell division (cytokinesis) and mitosis (nuclear division). The interphase cell usually possesses one or number of nuclei, thus, a few nuclei are not witnessed adjacent to a cell wall.

Explain how the human body cools itself.

Answers

Hi there!


There is a way that the human body cools itself, but it sounds so weird!


Did you know that when you sweat after doing something constantly, the sweat tries to cool the body down? It's true!


I learned this is physical science class, and we tested it for ourselves. We ran around a bunch of times around my old school and then we started sweating. Not too long afterwards, we started cooling down because of the sweat.


Weird, right?


Hope this helps!

Message me if you need anything else! :D
Whenever we sweat our body empty's salt out and we can cool of by simply our sweat drying. :)

it can be scientifically proven if you need reasons.

i really hope that this helps you a lot

What is the purpose of using a pedigree?a to study the causes of traits that are acquired during an organism’s life
b to understand patterns of inheritance in organisms
c to determine mating patterns in organisms
d to identify traits that are acquired during an organism’s life

Answers

The pedigree's purpose is to understand patterns of inheritance in organism. Examination of the pedigree utilizing the standards of Mendelian legacy can decide if a characteristic has an overwhelming or passive example of legacy. Families are frequently built after a relative harrowed with a hereditary issue has been distinguished.
The purpose of pedigree is to trace the ancestory. Therefore, the correct answer is B, i.e., to understand the patterns of inheritance in organisms. it helps in knowing that what characters are passed to the offsprings, what disease may be transferred to the offsprings, and also the mode of inheritance of the disease.
