The correct answer is B. Differences in the characteristics of individual trees

Explanation:

Evolution refers to the changes certain species of organisms experience over a long time that is mainly prompted by natural selection which occurs as changes in the environment or conditions make certain traits to prevail over time and others to disappear. This occurs in the case presented as drought makes trees with deep roots prevail over time while other trees disappear. This implies,s the factor that allows natural selection and evolution to occurs is the differences in the characteristics of individual trees or that some of the trees have deep roots that prevail while others with superficial roots tend to disappear.

Consider this equation: Kinetic Energy = mv2Which of those variables is changing as the skater moves up and down the track?
pav-90 [236]

Answer:

The changing variables are: v and KE

Explanation:

Given

KE = \frac{1}{2}mv^2

Required: What changes?

From the formula above:

KE=Kinetic\ Energy

m = Mass

v = Velocity

m: The mass of the skater is constant.

v: Moving up and down the track may change the velocity of the skater.

KE: When velocity changes, the kinetic energy also changes

So:

The changing variables are: v and KE

Fill in the missing words. naturalselection foundereffect geographicallyisolated species evolution
grandymaker [24]

Hi!


The ancestral finch founded a new population on one of the Hawaiian Islands. Due to the founder effect , allele frequencies of the first small population on one of the islands could have differed from their continental goldfinch-like ancestors. The process of natural selection resulted in adaptation and evolution of the island population into a new species over time. Some of the birds crossed to some of the other islands where they were geographically isolated and evolved into more species occupying different niches.


In terms of population genetics, founder effect is when there is a loss of genetic diversity as a result of the establishment of a new population by a relatively few individuals. Following such an establishment, natural selection is the process  which results in the genes of the fittest individuals of the population being selected over generations. This process ultimately results in evolution, and over time may give rise to new species. Geographical isolation is the physical separation of a population from another owing to geographical changes in the terrain or area. If two populations of the same species are geographically isolated, there is a great chance over time they may evolve into two different species.


Hope this helps!

Which compound is released by photosynthesis and used in aerobic respiration
slamgirl [31]

ATP

-Photosynthesis makes the glucose that is used in cellular respiration to make ATP. The glucose is then turned back into carbon dioxide, which is used in photosynthesis. -While water is broken down to form oxygen during photosynthesis, in cellular respiration oxygen is combined with hydrogen to form water.
