Answer:
A student is looking through a microscope at some cells of an onion root tip. Many of these cells are undergoing division since the root tip grows quickly and requires more cells. Which cell is going from metaphase into anaphase? W X Y Z
It's y
The cell Y is transitioning from metaphase to anaphase.
What is metaphase?
The chromosomes are at their second-most compacted and coiled state during the mitotic stage of the eukaryotic cell cycle, known as metaphase. These chromosomes, which contain genetic material, align in the cell's equator before being divided into the two daughter cells.
A phase of cell division known as "metaphase" (mitosis or meiosis). Individual chromosomes are typically dispersed throughout the cell nucleus. During metaphase, the cell's nucleus disintegrates and the chromosomes condense and migrate toward one another, aligning in the middle of the dividing cell.
The duplicate genetic material existing in a parent cell's nucleus is divided into two identical daughter cells during the third stage of mitosis, known as metaphase.

in the overall reactions of photosynthesis, the electrons from _____ are used to reduce _____.
In the overall reactions of photosynthesis, the electrons from water are used to reduce carbon dioxide.
During photosynthesis, electrons from water molecules are used to reduce carbon dioxide and fix it into carbohydrates while oxygen is produced as a result. The process happens with the help of radiant energy.
Even though the process of photosynthesis is a series of reactions that have been divided into light-dependent and light-independent, the overall equation of the process is written as:
[tex]6H_2O + 6CO_2 ---> C_6H_1_2O_6 + 6O_2[/tex]

which activity results from the action of hydrochloric acid on protein in the stomach?
Answer:
Hydrochloric acid contributes to protein digestion by supplying H+ which activates pepsinogen, the precursor to pepsin. Pepsinogen is secreted by chief cells in the gastric glands of the body and antrum of the stomach
I hope this will be helpful
Activation of pepsin results from the action of HCl. Pepsin is important for the digestion of proteins. Thus, partial digestion of proteins happens in stomach.
What are the functions of stomach?Stomach has an important role in the digestion of food. It is regarded as organ for temporary food storage.
Stomach contains various digestive enzymes, gastric juice and hydrochloric acid that prepares the food for complete digestion in the duodenum.
The walls of the stomach secrete hydrochloric acid which is responsible for imparting acidity to food. It is also important for killing of any bacteria present in the food. The acidic pH activates the enzyme pepsin which is required for the digestion of proteins into peptones.
Stomach also contains the gastric juice which kills any microbes present in the food. It is also important for nutrient absorption. Stomach also contains enzyme lipase to favour partial digestion of lipids.
Thus, stomach is important for the partial digestion of proteins and lipids.

when does an electron emit energy in the form of a photon?
Answer:
When the electron changes levels, it decreases energy and the atom emits photons. The photon is emitted with the electron moving from a higher energy level to a lower energy level. The energy of the photon is the exact energy that is lost by the electron moving to its lower energy level.
what is the difference between sister chromatids and homologous chromosomes?
Answer:
A sister chromatid refers to the identical copies (chromatids) formed by DNA replication of a chromosome, with both copies joined by a common centromere.
Explanation:
Homologous chromosomes may or may not be the same as each other because they are derived from different parents.
Explain the statements:

B. Mitochondria
C. Nucleus
D. Ribosome
PLS HELP!!
Answer:
Mitochondria
Explanation:
The organelle in which the above events most likely occur is known as the Chloroplast. Thus, the correct option for this question is A.
What is an Organelle?An organelle may be defined as a type of tiny organ or a subcellular structure that has significantly one or more specific functions in order to perform in the cell which is essential for the survival of living organisms.

integral proteins are important to maintain the strength of the cell membrane. true of false?
Answer:
false
Explanation:
Integral proteins are one type of membrane protein. They are constantly associated with the membrane, carrying out many different functions but they do not maintain the strength of the cell membrane. The sentence is False.
-----------------------------------
Plasmatic membranes are composed of lipids and proteins.
Among the proteins, we can find integral proteins and peripheric proteins.
Integral proteins are permanently associated with the membrane.
They accomplish many different functions such as substances transport, cellular receptors, cellular adhesion, among others.
According to how they are incrusted in the lipidic bilayer, integral proteins might be,
Transmembrane proteins ⇒ span the entire membrane⇒ present in every membrane cells
Monotypic integral proteins ⇒ attached to only one of the lipidic layersIntegral proteins provide structure to the plasmatic membrane, but they do not maintain its strength.
