Aroot is absorbing water from the soil. which route will the water travel inside the root?
a. cambium --> phloem --> xylem --> stele --> endodermis --> cortex --> epidermis
b. xylem --> phloem --> endodermis --> stele --> epidermis --> cortex --> cambium
c. epidermis --> cortex --> endodermis --> stele --> xylem --> phloem --> cambium

The answer is option C.

Explanation:

Plants absorb water through roots from the soil by the osmosis. Water enters in the root through the epidermis of root hairs to the cortex and enters in the endodermis from there water travels up to the xylem via stele. Water uptake can be facilitated by the two pathways: the apoplast pathway or the symplast pathway. Water uptake continues from xylem to phloem to cambium. So the correct answer is-

C. Epidermis --> cortex --> endodermis --> stele --> xylem --> phloem --> cambium

9.9 years

a = p(1 + rt) . . account balance after time t at rate r starting with principal p

3000 = 2500(1 + 0.0202t) . . filling in the given numbers

1.2 = 1 + 0.0202t . . divide by 2500

0.2 = 0.0202t . . . subtract 1

0.2/0.0202 = t ≈ 9.901

it will take about 9.9 years for the account balance to reach $3000.

"menstrual cycle is a complex cycle that consists of several processes. order of occurrence of steps in menstrual cycle are as follows:

1. high progesterone levels maintain the endometrium lining of the uterus.

2. endometrium lining breaks down and low levels of estrogen stimulate the pituitary to release fsh and lh.

3. fsh and lh stimulates the follicles to develop and the oocyte to produce estrogen.

4. rising estrogen levels suppress fsh production and development of other follicles.

5. a spike in lh causes follicle to rupture.

6. a breakdown of corpus luteum causes progesterone level to drop."
