What is the number of this particle in a carbon atom?

Biology
1 answer:
Anastaziya [24]2 years ago
5 0

Answer:

6

The number of protons is an element's atomic number and is the same for all atoms of an element. Carbon has atomic number 6 . So all atoms of carbon have 6 protons in their atomic nuclei. Carbon atoms also contain neutrons in their atomic nuclei, which may number 6 , 7 , or 8

How large may an air mass be?
denis23 [38]
Everything has mass. The mass of something never changes. 

Mass is measured using grams.

Air is not that heavy, but it certainly has mass because it takes up space.

For every one liter of air, their is 1.19 grams.

Q - Describe the Mitoses with the help of diagram. write its different phares and explain them.​
bonufazy [111]

Answer:

Mitosis is a type of cell division in which single haploid cell (n) or diploid cell (2n) divides into two haploid or diploid daughter cells that are same as the parent.

Mitosis occurs in somatic cells of plants and animals. In this cell division, the two daughter cells have the same number of chromosomes as that in the parent cells.

Mitosis consists of four basic phases: prophase, metaphase, anaphase, and telophase.

1.Prophase:-

It is the first visible stage in karyokinesis. The chromosomes appear as long coiled threads called chromatids. The chromatin becomes shorter, thicker and visible due to the condensation of DNA. The chromatins are now called chromosomes. Stainability of nucleus increase. Each chromosome starts to splits longitudinally into two sister chromatids. These sister chromatids are attached to each other at the centromere. The nuclear membrane and nucleolus start to disappear and by the end, it will be completely disappeared.

ii. Metaphase:-

Nuclear membrane and nucleolus completely disappears and simultaneously appearance of spindle fibers. Spindle fibers are attached to the centromere of a chromosome. The chromosomes are arranged on the equatorial plane. The process of gathering of chromosomes in equator is called congressional and plate formed is called metaphasic plate.

iii. Anaphase:-

The centromere of each chromosome splits into two sister chromatids and forms two daughter chromosomes. The daughter chromosomes are pulled towards the poles due to the contraction of spindle fibres and stretching of interzonal fibers. During polar movement, the chromosomes show different shapes i.e. J, U, V, L or I shaped in appearance. At the end of anaphase, each pole will get one set of daughter chromosomes. It is the shortest phase and is also known as a migratory phase.

iv. Telophase:-  The daughter chromosomes reach respective poles and uncoil and become thin, long and visible. The spindle fibres start disappearing and finally disappear. The nuclear membrane and the nucleolus reappear.

Two nuclei are formed at the end of telophase. Both the nuclei have the same number of chromosome as the parent cell. It is the last visible stage of karyokinetic and is also known as reorganization phase.

It is followed by cytokines or division of cytoplasm.

What part of the leaf is reasponsible for absorbing the suns energy
sattari [20]

Answer:

Inside the plant cell are small organelles called chloroplasts, which store the energy of sunlight. Within the thylakoid membranes of the chloroplast is a light-absorbing pigment called chlorophyll, which is responsible for giving the plant its green color.
