Arrange the following steps that occur during drought tolerance in plants in a correct sequence.

I. hormone ABA accumulation in the leaves

II. causes stomata to close

III. reduction in transpiration

IV. preventing further water loss

a. I, II, III, and IVII,

b. I, III, and IVIII,

c. I, II, and IV

d. I, III, II, and IV

I, II, III and IV.

Explanation:

Drought tolerance is the ability of the plant to survive and adapt to drought or arid conditions.

When plants encounter drought, they produce dress hormone called abssisic acid. These hormone then activate the cells receptors and the receptors cause some changes in the plants.

The receptor causes the guard cells of the stomata to close to reduce and cause cessation of plant growth to in order to reduce water consumption of plant.

Once the stomata is closed, there is decrease in transpiration which reduce water loss but still allow carbondioxide to enter.

Examples of drought tolerant plants are agaves, wallflower, lantana, lithops, portulaca e.t.c.

the correct answer is - d. china has a large and growing population.

the fact that china has a large (the biggest) population, and it is still growing, doesn't hinder the agriculture production in the country. in fact, it can for increased production in the agriculture, since there's more labor force, as well the sheer mass of people produces lots of scientists that come up with new inventions as to how to improve this sector. nice example is the inner mongolia region in china, in general dominated by the gobi desert, but few scientist came up with a nice idea as to how to make the region productive by using plants that are very resistant to droughts, so lots of people have been employed, and the region is becoming greener and greener each year, and the production of food in this region is also increasing.

i believe the answer is snake.
