The answer is (b.) fertilization
The fertilization is the stage where the egg cell or the
so-called ovum fused with the sperm cell which eventually leads the development
of the embryo or the zygote. The Embryogenesis starts when the zygote undergoes
mitotic divisions or also known cleavage process.
<em><u>Xylem</u></em> is a part of <em><u>Vascular bundle </u></em>which carry up <em><u>water</u></em> and <em><u>minerals</u></em> from roots of plant to its leaves.
So, the required answer is :
=》A. <em><u>Water and minerals</u></em>
There are three types of dominance. Incomplete, complete, and co-dominance. Complete dominance is when the dominant trait completely masks the recessive. incomplete dominance is when the dominant allele doesn’t completely mask the recessive allele, sometimes resulting in blending. Co-dominance occurs when both alleles are expressed at the same time.
c.Stomata are generally open during the day to remove excess water from the planet and closed at night to keep oxygen from escaping.
Answer:
See the answer below
Explanation:
The explanation I would give to the phenomenon is that<u> the round trait in peas completely covers or nullify the wrinkled trait when they are together.</u> In order words, <u>whenever a single the allele of both trait come together to form a new trait, the round trait allele dominates and mask the expression of the allele of the wrinkled trait</u>.
<em>This is what Mendel explained and dominance/recessive effects. The round trait was dominant over the wrinkled trait while the wrinkled trait was said to be recessive and can only be expressed when alone.</em>
