In some forests are cleared by burning .This produces carbon dioxide and ash. (a) Outline the environment effects of am increase in carbon dioxide in the atmosphere as a result of burning forests.

(b) The ash helps crops to grow bcuz it is rich in minerals, such as magnesium ions ,but it is deficient in nitrate ions.

Explain why nitrate ions and and magnesium ions are important for plants.
​

B. The ash helps crops to grow because it is rich in minerals, such as magnesium ions, but it is deficient in nitrate ions.

Explanation:

After the forest is being burned, ash and carbon dioxide increase on the surface of the ground. It is good for the plant to grow because the plant uses carbon dioxide for photosynthesis, and its root absorbs energy from the ground where ash is very good for the plant to grow.

the real answer is b. scintillation counter

"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."
