Answer:
resolution of psychosocial tasks is the answer
Explanation:
In this case, the type of character is the A nucleotide at position 45 is - C. Derived.
The derived characters or traits are that arose in the most recent common ancestor and passed on the lineage. It can be referred to as traits that are not present in older ancestors but in recent lineage.
Thus, the type of character is the A nucleotide at position 45 is - C. Derived.

Answer:
Explanation:
Derived kind of character is the A nucleotide at position 45.
Derived character: Derived kind of character is one that evolved in the lineage and leading up to a clade and that sets members of that clade apart from other individuals
Example of a derived character: the loss of a tail, a trait that first appeared in an ancestor of apes and man.
Only the strongest animals survive.
B.
Populations change over long periods of time.
C.
Life must come from other life.
D.
Parent organisms pass on traits they have acquired during their lifetime.
Answer: A. Only the strongest animals survive.
The theory of natural selection - the survival of the fittest suggests differential survival and reproduction of the organisms. This means the organisms that have better phenotypic advantage over the others likely to survive and reproduce in the adverse environment. Such phenotypic traits will be passed from the parents to the offspring and will promote the evolution of the species.
On the basis of the above description, the only the strongest animals will survive is the correct option.

Answer: True
Humans have impacted the rainforests through mining, agriculture and construction as rainforests are mainly occupied with large forests trees and vegetation. Human clear cut the forests to make the land available for the purpose of mining to derive economically valuable minerals from earth, construction of house and for agriculture. This has resulted in the extinction of large number of floral and faunal species from earth. It has decreased the percentage of forest cover on earth.
According to the question, it is true that Humans have impacted the rainforests through mining, agriculture, and construction.
How human impacted the rainforests through mining
Gemstones and Precious metals such as gold, copper, diamond are important resources that can be found in the rainforests across the world. Extracting these resources is harmful activities that contribute lot of damages to the rainforests ecosystem. It causes problem for the people that live close to the rainforests. Chemical pollution and deforestation from mining can have a great adverse effect on the rainforests environment. It also affects downstream aquatic habit.
How human impacted the rainforests through Agriculture
In the rainforests, large areas are cleared for pastoral farming because the demand of meat globally has increased the opening of cattle farms in the rainforests and this also cause deforestation which has adverse effect on the rainforests. Arable farming also contribute to the loss of tropical rainforests as many farmers are clearing the land to grow crops such as soya beans.
How human impacted the rainforests through Constructions
Road building has different of direct impacts on the rainforests. In most wet tropical rainforest, the cut and fill operation related with road construction can prevent easy flow of streams, increase flooding in the forest and can drastically increases erosion in rainforests. Construction of roads in the rainforest can discharge nutrients and chemical pollutant into water ways and create avenue of invasion for disturbing exotic species.
