Does this mechanism produce a change in individuals or populations? Explain
I am Lyosha [343]
<h2><u>Answer:</u></h2>

<u>mechanism:</u>  the process of evoluton .

Evolution is the process by which veriety of  modern organisms have descended from ancient ancestors. Evolution is responsible for both the remarkable similarities of all  0rganisms and the amazing diversity of that organisms  but exactly how does it work? Fundamental of  the  process of evolution  is genetic variation upon which selective forces can act in order for evolution to occur.

Examines the mechanisms of evolution focusing on:

•<u>Decent </u>: the  genetic differences that are heritable and passed on to the next generation successfully.  

• <u>mechanisms of change</u>:   Mutation, migration (gene flow), genetic drift, and natural selection are act as mechanism of change .  

• The random nature of genetic drift  and their effects .

• How variation, differential reproduction, and  heredity result in evolution natural selection .

• How different species can affect each other's evolution through co-evolution.

All of these mechanisms can cause changes in the frequencies of genes produce change in  in populations, and so all of them are mechanisms of evolutionary change. However, natural selection and genetic drift (genetic flow) cannot operate unless there is genetic variation among organisms.

Which of the following does NOT accurately state a transfer of carbon in the carbon cycle?
Doss [256]

Answer:

The point that does NOT accurately indicate a carbon transfer in the carbon cycle is that burning of wood and debris pulls carbon from the atmosphere to use as energy.

Explanation:

The carbon cycle involves the journey that carbon makes between living organisms and their surrounding environment, i.e. the entire biosphere, geosphere, hydrosphere and atmosphere, and is therefore considered a biogeochemical cycle.

In living organisms, inorganic carbon is taken up by plants to make organic molecules, which will be used by animals - which release CO₂ into the atmosphere - or dead organic matter provides carbon to the soil.

The combustion of wood and debris involves the oxidation of a combustible material -which requires oxygen from atmosphere- to then release CO₂ as a product. So it is incorrect to say that burning of wood and debris pulls carbon from the atmosphere to use as energy.

Suppose that in another world, DNA does not undergo semiconservative replication, but instead a conservative mechanism is used.
Liono4ka [1.6K]

Answer:

c. ¼ heavy, ¾ light

Explanation:

DNA replication follows semi conservative model which means that both the strands separate during replication and the newly formed DNA molecule has one old and one new strand. If instead of semi conservative, conservative mechanism is used, old strands will not separate from each other and the two newly synthesised DNA strands will come together to form a DNA molecule.

Here the cells were first grown in heavy 15N medium so all the DNA molecules had 15N and thus were heavy. Then the cells were transferred to 14N medium where only lighter 14N were available for replication process.

In first generation, 14N DNA molecules were synthesised from 15N DNA molecules so 1/2 DNA molecules were 15N and other half were 14N. In the second generation, 14N molecules will give rise to new 14N molecules and 15N molecules will also give rise to 14N molecules hence 1/4 molecules will be 15N (heavy) and 3/4 will be 14N (light).
