Answer:
a. His father's mother lacks a widow's peak.
Explanation:
To find out if you are homozygous or heterozygous, you need to find out the genotype of your parents. This you do by looking at their phenotype, their grandparents, uncles. After that it's easy to find out if it's homo or heterozygous. Of course, this need not even be done when it is a characteristic determined by recessive alleles, but in the case of a characteristic determined by dominant alleles, such as widow's peak (W), we must visualize the characteristic in the individual's country.
Since the man, shown in the question above, has widow's peak, so that your child knows if he is homozygous or heterozygous, just look at whether the trait is present in this man's parents. If his mother doesn't have widow's peak, we automatically know that the man is heterozygous, and that was his father's estate. However, if this man's mother has widow's peak and his father does, then the man is homozygous.
For the answer to the question above, I believe the answer based on the given information above, <span>the alleles for color and vision segregate independently during gamete formation. That's why the two Labradors are different. The other one is healthy and the other one is not. </span>

Answer:
Termites can spend time building mounds there by aerating the soil and allowing moisture which support the growth of shrubs, grasses, tress.
Through their mounds, their droppings contain phosphorus and nitrogen which add to the soil nutrients and supports grasses, shrubs and trees growth.
Explanation:
Termites are commonly found in Savannah ecosystem in African areas and they build mounds. Termites mounds consist of their fecal droppings , saliva and clay.
Termites can spend time building mounds there by aerating the soil and allowing moisture which support the growth of shrubs, grasses, tress.
Through their mounds, their droppings contain phosphorus and nitrogen which add to the soil nutrients and supports grasses, shrubs and trees growth.
A species that is habitat specialist and lives at the highest elevation.
Explanation:
An ecosystem consist of plants, animals as well as micro-organisms but due to climate change the plants as well as animals are in danger . The case that has been provided in the question where due to climate change the temperature rises as a result the species living at the highest elevation are in problem .
Due to rise in temperature the snow is melting and the sea water level is rising. The animals and plants adapt themselves according to the climate where they are residing but suddenly if climatic change take place they will be unable to survive.
The animals which are mostly affected due to climatic change are snow leopard, polar bear, giant panda.
