Answer:
-100
Explanation:
If the total water potential in the soil around a plant root were -50 kPa, water would move from the soil into the root if the water potential inside the root cells were -100 kPa.
The water potential of a substance represents the measure of potential energy in water molecules in a system as compared to that of pure water. It is also a measure of the tendency of water to move from one region to another.
<em>Usually, water will move from the region of high water potential to the region of low water potential. Hence, for water to move from the soil into the root, the root must have a lower water potential than the soil.</em>
The soil had -50 kPa water potential, hence the only option that is lower than -50 kPa is -100.
The correct answer is -100 kPa.
Answer:
The answer is E.
Explanation:
The question is incomplete. Here is the complete question:
An XXY chromosome constitution produces ________ development in humans and _________ development in fruit flies.
a. female; female
b. male; male
c. female; male
d. male; female
e. male, intersex
Normally, possessing two sex chromosomes for humans, having 3 sex chromosomes is an abnormality but it still results in a development of a male, who is infertile.
Fruit Flies are a species which possess 3 sex chromosomes normally, and in the cases in which there are 2 X choromosomes, it encourages the development of intersex fruit flies. Situations where there are 3 X choromosomes present result in female fruit flies and where there is only a single X chromosome result in male fruit flies.
I hope this answer helps.
