Answer:
Double fertilization. (Ans. 5)
Explanation:
Double fertilization is a complex fertilization process occurs only in flowering plants known as angiosperm. In this process two male gametes or sperm cells fertilization occurs, first one is fertilized with the egg and form the zygote and second one is fuses with the 2 polar nuclei which cause the formation of endosperm.
In double fertilization, after the process of fertilization, the tissue of ovary forming the fruit and fertilized ovule of an ovary forming the seed.
Answer:
Chromosomes at the conclusion of Meiosis I - 
Double-helical molecules of DNA at the conclusion of Meiosis I - same as that of parent cells
Explanation:
Given
Number of chromosomes in the diploid cells of Aliens from the planet Zorg 
In the Meiosis I cell division , a cell divides to produce two diploid cells with exactly the same amount of DNA as that of original parent cell.
However, the number of chromosomes is reduced to by half at the end of meiosis I
After Meiosis II, four haploid cells are produces with half the amount of DNA as that of original parent cell
Thus,
Chromosomes at the conclusion of Meiosis I -
Double-helical molecules of DNA at the conclusion of Meiosis I - same as that of parent cells
Answer:
Alternate form of gene
Explanation:
An allele is a variant form of a gene. Some genes have a variety of different forms, which are located at the same position, or genetic locus, on a chromosome. Humans are called diploid organisms because they have two alleles at each genetic locus, with one allele inherited from each parent.
The type of connective tissue that can be used more than once is the loose connective tissue. It can be used in instances such as organ transplant.
The Theory states if my memory is correct. All living things contain one or more cells. And all living cells Come from preexisting cells. Robert Hooke discovered the cell while, Theodor Schwann and Matthias schleiden are credited to the creation of the cell theroy
