Answer:
The scientific study of life, called <u>Biology</u><u>, </u>can be organized around several themes. As the biological hierachy builds from molecules on up to ecosystems, each level has <u> emergent properties</u> that result from interactions among component parts. Life's basic unit of <u>structure and function</u> is the cell, which occurs in two basic forms- prokaryotic and eukaryotic . As organisms interact with the environment, <u>nutrients and chemicals</u><u> </u>cycle within an ecosystem, while energy flows one way from sunlight -> chemical energy -> heat. According to the core theme of <u>evolution </u>all of life is related by common descent. Life was diversified as <u>natural selection</u> had led to the gradual accumulation of adaptations that fit populations to the environment.
Explanation:
Emergent properties- Properties that is exhibited by a group of individuals as a result of interaction among them.
Evolution- the process by which populations develop new characteristic and become more efficient than their ancestors.
Natural selection- A phenomena in which only fittest organisms of a population are allowed to survive in a given environment. This play a key role in evolution.
The answer is B. Cnidarians
Cnidarian body has no left or right side, only tom and bottom surfaces. If you divide cnidarian a about central point, you will get equal parts. So, cnidarians are radially symmetrical animals. This group includes hydroids, jellyfish, anemones, and corals. In all groups, animals have stinging cells on tips of tentacles. They use them to capture the prey. Their name literally means stinging creatures.
Answer:
210
Explanation:
Frequency of dominant allele is represented by "p"
and frequency of recessive allele is represented by "q"
Given
Thus,
As per Hardy Weinberg's second equation of equilibrium -
Substituting the given values in above equation, we get -
So the total number of heterozygous individual is equal to
The population increases due to the fact that birthrate becomes higher than the death rate.
The correct answer is B since it shows a decline.
But why put the answer ? Lol
