adoni [48]

Answer:

Stomata are the organs present on the stem and leaves of the plant and help in the gaseous exchange and evaporating water present in the aerial parts of the plant. Mainly leaves stomata plays role in gaseous exchange and transpiration which is the evaporation of the aerial water of plants by opening and closing the stomata. Stomata are small pores mostly and normally present under the leaves and regulated by the guard cells, dum bell shaped cells to close or close it.

Other than closing and opening the stomata, stomata density also can affect the rate of gas exchange as well as transpiration. Stomata density is the presence of the numbers of the stomata per unit area. In heat or sunny area the stomata density is higher than the shady or dark area to increase the transpiration in order to cool down the leaves of the plant which prevent the chloroplast proteins to denature.

Please answer, I'm stuck :/
Artist 52 [7]

Answer:

<em>A) The water is cooler than the land and the wind blows towards the beach</em>

Explanation:

<em>During summer hot day, the land and ocean both get heated. But since the specific heat capacity of water is higher than the land , it takes longer time for ocean to heat up than the land. Since during day land is warmer than ocean, hence the air above it also gets warm and rises away. While the air over ocean is comparatively cooler than the air above on land and hence it sinks down and starts moving towards the land thereby causing sea breeze.</em>

Verizon [17]

I believe this represents the goal of not doubting anything in science. Paleontologists found a species that was previously known to be extinct, which means that there could be many more discoveries like this that could change history as we know it. I bet this taught scientists to not have a fixed mindset when it comes to searching for more answers on a topic.

I hope I helped!
