Answer:
As insect nymphs grow larger, their exoskeleton becomes too tight and they must replace it. Once a nymph outgrows its exoskeleton it will go through a process called molting, in which it leaves the old “skin” or exoskeleton behind. The new “skin” will harden and become the new exoskeleton
Explanation:
Answer: Implantation
Explanation:
The uterus is the main site for the implantation of the embryo. It is the place where the embryo spends 9 months in the mother.
When the male and female gamete combine they form a zygote. It gets implanted in the uterus and then there is cell division and the development of embryo takes place there only.
Any abnormalities in this region will interfere in the process of implantation.
Answer:
All of the genes controlling the traits behaved as if they were located on different chromosomes.
Explanation:
Mendel's experiments with pea plants lead to two principles:
- Law of segregation which states that the pair of alleles (for any trait) of each parent separate, meaning that one allele passes from father and another from mother to an offspring.
- Law of independent assortment which states that different pairs of alleles (for different traits) are passed to offspring independently of each other (traits are located on different chromosomes).
