Answer:
Egg and sperm cells have to have half the number of chromosomes as in body cells so when they combine to form a zygote, the zygote is diploid and has the correct number of chromosomes. This explanation describes why meiosis produces haploid cells.
Explanation:
Meiosis is a type of cell division in which four haploid cells are produced from a diploid parent cell having two copies of each chromosome, where the number of chromosomes in the parent cell is reduced to half by undergoing DNA replication and nuclear division. Diploid cell contains two copies of each chromosome, one inherited from mother and the other from father while haploid cell contains only one copy of each chromosome. Examples of diploid cells (somatic cells) are skin, blood, muscle cells etc. Eggs or ovum (female gametes) and sperm (male gametes) are haploid reproductive cells. If the total number of chromosomes in a diploid cell is represented as '2n', then the number of chromosomes in a haploid cell is 'n'. During the fertilization process in an organism, the correct number of chromosomes is restored when the haploid male and female gamete combined to form a single diploid zygote, which is the first developmental stage of an organism.
Answer:
The correct answer is D) dendrites; cell body; axon
Explanation:
Neurons cells makes the nervous system and are responsible for carrying the information from one body part to the other body parts. A neuron has three distinct parts dendrites and axon.
Dendrites are the neurons extension which receives the impulse and transfers to the cell body. We can link dendrite with our fingers. Cell body is a spherical part of neuron like our palm and it controls all functions of the cell. Then from cell body signals are transferred to axons.
Axon is a long part of the nerve cell like our hand which helps in transmitting the signals to the next neurons. Therefore the correct answer is D.
The soil has to be not too acid or not too basic
