what hormonal change occurs after fertilization that causes the endometrial lining to remain intact so that the fertilized egg c
tino4ka555 [31]

The answer is the pituitary gland secretes follicle stimulating hormone, which acts on the follicles and stimulates them to produce progesterone.

The endometrial lining is where the fertilized egg implants, or burrows and attaches itself to the uterine wall, where it will continue to grow and be nourished. There are three layers of the uterus: The perimetrium is the outer layer, the myometrium is in the middle, and the endometrium is the inner layer of the uterine wall.

in pea plants, purple flowers (p) are dominant over white flowers (p). Show the cross between two heterozygous plants
Ostrovityanka [42]

Answer:

       <em>P      p</em>

<em>P</em>    PP   Pp

<em>p    </em>Pp    pp

PP=Homozygous purple

Pp= heterozygous purple

pp=homozygous White

Explanation:

I tried to type out the cross. The bold letters are the heterozygous  plants that you are crossing. and the normal letters are the offspring of the two heterozygous parents being crossed. Heterozygous means they are different alleles. Homosygous means the same alleles are present.

heterozygous= Pp

Homozygous= PP or pp

I hope this was the answer you were looking for!

Why is it more common for birds to have nests with a few eggs rather than just one or a lot?
Vlad1618 [11]

Explanation:

The large size of a egg makes it difficult for the female to retain more than a single one egg at a time - carrying eggs would make flying harder and require more energy. (Bird eggs vary in size from the tiny 0.2 gramme eggs of hummingbirds to the enormous 9 kilogram eggs of the extinct elephant bird.)

Just as an aircraft cannot fly if it is overweight, all female birds must dispense with the fertile egg as soon as it is formed. And because the egg is such a protein-rich high-nuitrition prize to all sorts of predators, birds must find a secure place to hatch their eggs. Although birds' eggs appear to be fragile, they are in fact extremely robust. The oval shape applies the same rules of engineering as an arched bridge; the convex surface can withstand considerable pressure without breaking. This is essential if the egg is not to crack under the weight of the sitting bird. It takes 26 pounds of pressure to break a swan's egg and 120 pounds to smash the egg of an ostrich.
