Producers generally require sunlight to make energy. Since there isn't sunlight at the bottom of the lake, they are unable to photosynthesize and produce energy they need to survive.
Answer: In explanation
Explanation:
Once the sun's energy reaches earth, it is intercepted first by the atmosphere. A small part of the sun's energy is directly absorbed, particularly by certain gases such as ozone and water vapor. Some of the sun's energy is reflected back to space by clouds and the earth's surface.
The following questions are answered below.
Explanation:
a. They have 14 chromosomes that occurs in 7 pairs which has X and Y sex chromosomes. They are diploid.
b. They have 7 pairs of chromosomes that includes X and Y sex chromosomes. They are diploid.
c. The last pair of chromosomes are the sex chromosomes. The previous pairs are called the autosomes.
d. If the Tasmanian devil has 14 chromosomes , then it is a boy. If the Tasmanian devil has 28 chromosomes , then it will be a female.
e. The one extra chromosomes are the egg or sperm that means three in fertilized egg. They are called as Trisomy.
f. The Tasmanian devil's will not get Down syndrome but some times there may be trisomy if there are three chromosomes instead of two.
Answer;
A. leaf to mouse
Explanation;
-Considering the fact that the amount of energy at each trophic level reduces as it moves through an ecosystem from the lowest trophic level which happens to be producers (plants). And about 10 percent of this energy at any trophic level is transferred to the next level since the rest is lost largely through metabolic processes as heat.
-It means that the lower the trophic level the higher the energy obtained, for instance from producers to primary consumers, more energy is passed since it is the first passage of energy.
Answer:
IAi
Explanation:
The genotype for O blood is ii. So his mom must have given him an i allele. So he has at least one i allele.
But since his phenotype is A -- he expresses A -- there must be one IA allele. Otherwise, if he had both ii, he would be an O-type blood.
So his genotype must be IAi.
