Explanation:
Create the column headings "Reactants" and "Products". The two row headings should be "Photosynthesis" and "Cellular respiration".
Before filling in the table, make sure you know what the products and reactants from photosynthesis and cellular respiration are.
Remember reactants are the 'before' on the left, and products are the 'after' on the right.
<u>Photosynthesis</u>:

<u>Cellular Respiration</u>:

See attachment for how the table could look.
Unfortunately this question is incomplete as it is a multiple choice question. The following options are provided:
<span>A) body cavity between body wall and digestive system
B) number of embryonic tissue layers
C) type of body symmetry
D) presence of Hox genes
E) degree of cephalization
The answer is D: presence of Hox genes

Hox genes are a group of genes that determine the basic structure and orientation of animals.
The menstrual cycle is practically controlled by a system of hormones that is necessary for reproduction, and when the hormone reaches a heightened level, something called estradiol is made, then the stimulation of the ovaries by a luteinizing hormone.
Once that hormone begins developing, the ovaries make an egg that quickly becomes an ovum. The ovary then releases one egg or two during ovulation. The endometrium (the part that sheds its own cells for the menstruation) peaks after ovulation and changes the lining of the uterus to prepare for the hectic process of pregnancy and child labor.
Hope that was helpful.
