The first one is A and the second one is probably A unless it could be D.. Not completely sure.
Step-by- step-Explanation:
- Archaebacteria are very similar to Bacteria with respect to their cell size,prokaryotic organisation,circular DNA etc.
- Archaebacteria very similar to Gram-positive bacteria on the basis of cell structure.
- Both bacteria and Archaebacteria have several similar Metabolic Pathways.
- Unlike Bacteria Archaebacteria are habitants of extreme climates like hot springs and ice capped continents.
Thus Archaebacteria are much alike to Eubacteria.

Women have a tendency to retain water during part of the menstrual cycle because estrogen mimics the action of <u>aldosterone</u>.
Explanation:
The female sex hormones produced by the ovary (estrogens and progesterone) are substances that, through the blood, will carry messages to all the organs of the female genital system (uterus, tubes and ovaries) to achieve their correct function. Aldosterone concentration normally increases at the time of ovulation and remains elevated during the luteal phase of the menstrual cycle. Women present during the premenstrual phase, compared to the luteal and follicular phases, an increase in body weight, due to an increase in fluid retention, this because the menstrual cycle modulates the renin-angiotensin-aldosterone system. High levels of estrogen and progesterone in the mid-luteal phase are associated with a greater increase in adrenal and renal hormones and retention of more volume.
