Answer:
1 or 100%
Explanation:
Assuming that the allele B (brown) is dominant over the allele b, crossing the father and the mother:
BB x bb
Bb Bb Bb Bb (you can also see the Punnet's square)
All the offspring would exhibit the dominant phenotype which is brown. Hence, the probability of the offspring having brown eyes is 100% or simply 1.
Answer: Experimetal ablation
Explanation: Experimental abaltion
It can be defined as the most common procedure that is used by the scientists in his laboratory. This procedure includes the removal or destruction of a part of brain for studying the functions of the regions of brain.
Then the behavior of the animal is observed to see which part of the brain is responsible for which type of behavior. This can be an unethical practice so it is not used on human beings and is only used in animals.
ANSWER:
The effects of increasing or decreasing the nutrient levels in an aquatic food webs is described in the explanation.
Explanation:
If the nutrient levels in an aquatic food web increase moderately then it will result in increased production of the primary producers and the consumers.
But if the nutrient levels are increased excessively, like in eutrophication, then the increased level of nutrients will result in overproduction of the consumers like fishes, etc. Hence, there will be a scarcity of resources like oxygen in the water to support them and this will lead to a decline in biodiversity of the aquatic food web.
If the nutrient levels are decreased, then there will be competition for resources among the species which will ultimately lead to the decline of some species from the aquatic food web.

Survival of the strongest... an organisms strength does not affect the natural selection process. Natural selection is adapting the species to be able to better survive in its environment. In order to better survive, an organism does not to be strong. e.g. a plant is probably not a “strong” organism and natural selection doesn’t change that in most cases
