Which germ layer develops into bones, kidneys, bladder, ovaries or testes, blood, and muscles, including the heart?
a. mesoderm
b. ectoderm
c. blastula layer
d. endoderm

Mesoderm is the type of germ layer develops into bones, kidneys, bladder, ovaries or testes, blood, and muscles, including the heart.

Option A

Explanation:

The end of the gastrulation phase of living organism is marked by the formation of three germ layers namely ectoderm layer, mesoderm layer and entoderm layer.

Each of the layers which are mentioned gets converted into different structure. The Mesoderm gets converted to connective tissue, ligament and smooth muscles. The heart dividers by blood, lymph vessels and cells.

what's the

it's the cell cycle, but cytokines is when the cell divides.

theres 3 stages interphase,mitosis,and cytokines.

interphase prepares the cell for division.

mitosis is the process of dividing the cell,it has 4 parts interphase,anaphase,metaphase,and telophase.

lastly there's cytokines,that's when the cell divides into 2 daughter cells
