The answer is 1000% D) Plant cells, take in small molecules through the cell membrane
Bacteria may affect plants in a number of ways. Diseases have been mentioned, but most bacteria co-exist with plants quite easily. Several bacteria are involved with the transitions of nutrients and make nutrients such as nitrogen plant available (the plant is only able to absorb some nutrients in certain molecular forms). While other bacteria convert nutrients and toxins into forms unavailable to the plant.
Other bacteria make Some bacteria, Rhizobia in particular, develop symbiotic relationships with some plants. Rhizobia convert atmospheric nitrogen into ammonium which is plant available. In exchange, the plant provides Rhizobia with shelter (a root nodule) and food (photosynthates).
Answer:
The correct answer is- iodine
Explanation:
Thyroid glands is an important endocrine gland of the body which release hormone called thyroid hormone in the blood. It plays an important role in metabolism, brain development, and function, muscle control, etc.
The active form of thyroxine is triiodothyronine and the formation of thyroid hormone requires the availability of iodine. Four iodine atoms are present in thyroxine and 3 is present in triiodothyronine. Without iodine, they can not be produced.
Therefore iodine is the essential element that is required for the manufacturing of thyroxine and triiodothyronine.
Answer:
The options
a. riboflavin
b. vitamin D
c. pantothenic acid
d. folic acid
The CORRECT ANSWER IS d.
d. Folic acid
Explanation:
Having a healthy baby means staying healthy. Getting sufficient folic acid each day — mostly before conception and at early pregnancy as it reduces risk of serious neural tube defects (partial development of the brain and spinal cord) to a very large extent.
Folic acid (or folate) is a B vitamin (B9) found majorly in dark green vegetables (broccoli and spinach), legumes(beans and peas) and enriched grains.
It is essential for all women of childbearing age to get sufficient folic acid (necessary for cell growth and development plus DNA formation too)— not just those who are trying to conceive.
Answer:
The correct answer is
C. Constant high pressure
Explanation:
Constant high pressure is not a factor that causes weathering on the earth surface.
Temperature, air and water affects how a rock changes through time. They have the capacity to cause physical disintegration and chemical decomposition of rocks.
