This cell is getting ready to divide. The instructions to form another cell are inside the chromosome, which are found in the nucleus. The correct option is A.
The thread-like components known as chromosomes are found in the nucleus of both animal and plantcells. Protein and a single molecule of deoxyribonucleicacid make up each chromosome (DNA).
DNA is passed down from parents to children and contains the precise instructions that give each kind of living thing its individuality.
DNA may be precisely duplicated during these celldivisions thanks to chromosomes. So, once more. Our cells' nuclei include chromosomes, which enable precise DNA duplication during cell division. This guarantees that our internal processes go smoothly and effectively.
The cell is preparing to split into two. The chromosomes, which are located in the nucleus, contain the instructions for creating a newcell.
Thus, the correct option is A.

Answer:
I wont be able to answer all of them but: 1. C
2. Compound
Explanation:
A positive charge is called a proton, no charge is a neutron and a negative charge is a electron
When atoms are combined they are called a compound.

Heredity refers to the process in which DNA is transmitted from parent to offspring, determining trait inheritance. DNA contains the genetic information that informs the traits of the offspring.
The key feature of living organisms that is best described as the transmission of DNA from parent to offspring is called heredity. Heredity is a fundamental biological process that refers to the passing on of genes from one generation to another. Within this process, DNA plays a crucial role as it contains the genetic material that determines the traits of an offspring. For example, you might have the same eye color as your mother because she passed on the specific sequence in her DNA that determines eye color

Answer:
The non-critical factor when a person begin an exercise program is finding friends who like to exercise the same way you do.
Explanation:
Physical exercise is an ideal way to stay healthy. It is a personal activity that should be done in the best way and with a minimum risk. Finding friends who like to exercise can contribute to motivation, but it is not an indispensable element when establishing a personal exercise routine.
Since it is a personal activity that affects an individual's health, personal factors should be considered when establishing a exercise program.
Regarding the other options, which are important factors for the exercise :
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.
