Answer:
The yellow leaf was not exposed to the sun so it can't produce sugar.
Explanation:
The yellow region of the leaf didn't produce sugar because it wasn't exposed to sunlight. Part of the leaf was exposed to the sun, thus this leaf produced sugar, while the yellow part of the leaf did not because it was not exposed to the sunlight.
Answer:
False
Explanation:
Rearrangements on introns and transposons usually don't cause severe consequences because those sequences are not part of coding genes and therefore cannot code for proteins, and if a rearrangement occur within a coding sequence of a gene might cause an incomplete and non-functional protein causing severe consequences to expression levels of that particular gene.
Stomata close when the vacuoles in the guard cells fill with water and the cells become turgid. The environmental stimulus that causes this response is the change from light to dark. During the day, heat from the sun causes evaporation in the leaves, which leads to water loss from the leaves, by way of the stomata, in a process known as transpiration. At night, the absence of the sun's heat slows the rate of evaporation, causing the vacuoles in the guard cells to fill with water by way of osmosis, causing the guard cells to become turgid and seal off the stomata.
Answer:
I'll give this a shot I think it's B!
Explanation:
It is colder at the top of a mountain because there is less air pressure. The same amount of heat is now in a larger area so it is more spread out.
