Answer: Meiosis; fertilization
In the human life cycle, diploid cells undergo a cell division process called meiosis. The resulting haploid cells later fuse during fertilization which regenerates diploid cells.
Explanation:
Diploid cells possess two basic sets of chromosomes known as homologous chromosomes. They undergo a two-step meiosis (Meiosis I and II) to yield four haploid cells with half the original chromosome number of the parent cell. These haploid cells are called sex cells or gametes.
The male and female gametes (sperm and egg) then fuses during fertilization to form zygote, a single cell with two sets of chromosomes (diploid number). Then, it undergoes mitosis to regenerates diploid cells with the same chromosome number as found in the zygote.
Answer:
Phylum
Explanation:
Taxonomy is the classification of living things based on their feature similarities
Phylum is the second highest taxonomical classification between kingdom and class
<span>The correct answer for the question is D. Pine needles developed as a result of a beneficial mutation that increased the survival of plants the survived to reproduce and would then pass on the beneficial mutation to its offspring. Pine needle is the needle like leaf of a pine tree. This possible origin of pine needles from primitive narrow-leafed plants is an example of natural selection. Mutations changes the sequence of amino acids in a way that the phenotype expressed will give the organism advantageous characteristics. </span>
