Answer:

Light, water, and carbon dioxide

Explanation:

Bacteria are the oldest beings on Earth and are present almost everywhere - air, water, soil, air, dust and even volcanoes; and for that reason they are considered the most abundant living beings on the planet. Many people believe that bacteria only cause disease, but there are many bacteria that are used by man for beneficial things like lactobacilli, for example.

The first bacteria were very important for creating the atmosphere we know. These bacteria produced energy through light, water and carbon dioxide.

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!

In chemiosmotic phosphorylation, what is the most direct source of energy that is used to convert ADP+ Pi + ATP?
Kazeer [188]

Answer:

The correct answer will be option-D.

Explanation:

During the electron transport chain, an electrochemical gradient is established due to the movement of electrons.

The high number of protons gets accumulated in the intermembrane space of the mitochondria whereas less number of protons present in the matrix.

The protons are pushed from the outer membrane to matrix through ATP synthase where the movement of ATP causes synthase to spin and bind ADP and Pi to produce ATP.

Thus, option-D is the correct answer.
