Answer:
Explanation:
The resolving power of the microscope is dependent upon the objective lens. It can be measured by the ability of the lens to differentiate between the two lines or points on the specimen under observation. The more the resolving power the smaller will be the distance between the two lines or points that can be distinguished.
The following are the two ways that can be used to enhance the resolving power on the microscope:
Using a lens that has a higher aperture.
Decreasing the amount of light being entered into the microscope that means using light of less wavelength.
If a parent cell has 46 chromosomes, how many
chromosomes will be present in each daughter cell after
mitosis?
А
12.
B
23
46
D
9
2
Answer:
B
Explanation:
Its 23 in mitosis cell division
tube, ovary, uterus, vagina.
The journey of the egg from ovulation to release during menstruation includes the ovary, fallopian tube, uterus, cervix, and vagina.
The journey of the egg from ovulation to release during menstruation involves several structures in the female reproductive system. The process begins with ovulation, during which an egg is released from the ovary. The egg then travels through the fallopian tube, where it may be fertilized if sperm is present. If the egg is not fertilized, it continues to the uterus and is eventually shed during menstruation through the cervix and vagina.
Answer:
It allows rapid conduction of water from one vessel element to the next.
Explanation:
Vessels are one of the two types of conducting cells of xylem. Vessels are made of vessel elements. Vessel elements are the individual cells with perforation plates. The perforation plates have large holes (perforations). Perforation plates of adjacent vessel elements allow easier conduction of water from one vessel element to the next.
The perforated end walls of vessel elements allow these conducting cells to conduct water more readily than tracheids. Stacking of vessel elements with perforated end walls make the vessel like a water pipe through which water is being readily conducted.
Schleiden and Schwann suggested the cell theory. It is stated that a single cell makes up every living thing. It implies that the structural and basic unit of life is the cell.
Understanding how cells form, grow, and die enables us to comprehend how all living things function.
Our comprehension of a variety of subjects, including as how new life is created, why organisms take on particular forms, how cancer spreads, how diseases can be treated, and more, is assisted by this collection.
Cells make up all known living things. The structural and operational unit of all living things is the cell. The chemical makeup of each cell is same. Cells are where all of life's energy flow (metabolism, biochemistry) takes place.
Therefore, adult human form singled cell zygotes.

Answer:
The adult human forms from the single-celled zygote.
Explanation:
The cell theory was put by Schleiden and Schwann. It is said that all the living organisms made up of from a single cell. It means the cell is the structural and fundamental unit of life. In human beings, it is also seen. The human comes from the fertilization of haploid sperm and ovum. The zygote is the single fertilized cell that undergoes cell division to form multicellular organisms. The single-cell zygote becomes a multicellular gastrula and forms the 3 germ layers. These three germ layers later form different tissues and organs by organogenesis. This happens due to the mitotic cell division. Thus an adult human will form and the cell division continues till the death of the individual. This process indicates how a single-celled zygote forms the multicellular human.
Answer: Food
Explanation: Of course, animals need food in order to gain mass. The food is used to transfer into cells, forming tissues, skin, and muscle to the animal.
