Explanation:

Answer 2

During fertilization in angiosperm, two fertilization events take place. One fertilization produces the zygote another fertilization event produces the endosperm that nourishes the seedling as it grows.​

What is the fertilization process in angiosperms?

Angiosperms are characterized by a double fertilization event in which one fertilization produces the zygote and the other produces tissue, called endosperm, within the seed.

After double fertilization, a post-fertilization event occurs, that specify triple fusion, the PEN (primary endosperm nucleus) then grows into the endosperm.

Therefore, in this event, one sperm fuses with the egg to form the 2n zygote, and the other sperm fertilizes with two polar nuclei to create the 3n endosperm is known as double fertilization.

take two springs and 4 pins. (springs should have loops or hooks at terminals to attach to pins.)

Now get two pins and pin them at a certain distance apart.

take the first spring and attach its two terminals to the pins.

Repeat the above procedure, but double (increase the distance x2) the distance between two pins.

Now you have to measure how many coils are there within 5cm of the two springs.

you'll observe that the second spring has half the coils of the first spring within 5cm.

In here no. of coils is the frequency

5cm length is time.

distance between coil is the wavelength.

Answers

When the concentration of a substance on one side of the membrane is different from its concentration on the other side of the membrane, the substance is said to exhibit a concentration gradient.

CONCENTRATION GRADIENT:

Concentration gradient is a term used to refer to a difference in solute concentration on opposite sides of the membrane of an organism.

If the concentration on the external part of a cell is higher than that of the internal part of the cell, a concentration gradient is said to have occured.

Concentration gradient is the basis of osmotic movement of water into and out of a cell.

Therefore, When the concentration of a substance on one side of the membrane is different from its concentration on the other side of the membrane, the substance is said to exhibit a concentration gradient.

How do human cells resulting from meiotic division differ from human cells resulting from mitotic division?

Answers

The human cells resulting from meiotic division differ significantly from the cells resulting from mitotic division because :

Mitosis produces two diploid (2n)somatic cells that are genetically identical to each other and the original parent call,

whereas the meiosis produces four haploid (n) gametes which are genetically different from each other and the original parent cell as they are germ line cells.

Difference between mitosis and meiosis :

Mitosis is a fundamental process for life as our cell divides by this method in the development and growth of the body.

The cell duplicates all of its contents, including chromosomes and splits to form two identical daughter cells. This takes place in somatic cells.

Meiosis ensures humans have the same number of chromosomes as this takes place in germ cells like egg and sperm cell and produces half the number of chromosomes(n) and during fertilization they unite and become double that is 46 chromosomes.
