All BUT one action will help increase the accuracy of a scientific experiment. It is

Genetic mutation which can lead to diversity between organisms can be caused by

Sergio039 [100]

Answer:

DNA

Explanation:

Mutations are changes to an organisms DNA that creates diversity within a population by introducing new alleles. Some mutations are harmful and are quickly eliminated from the population by natural selection harmful mutations prevent organisms from reaching sexual maturity and reproducing.

within a forest ecosystem, there is a large amount of diversity among members of a warbler species. of the following stages of m

anzhelika [568]

Crossing over occurs between homologous chromosomes, and is closely involved in genetic variation. The stage that most contributes to diversity is stage C, where you can see chromosomes after crossing-over.

----------------------------

There are different mechanisms involved in producing genetic variation among descendants. These are,

Crossing-over between homologous chromosomes (prophase 1),

Random lining of homologous chromosomes (metaphase 1),

Random fertilization

The Crossing-over events occur between two homologous chromosomes in the equatorial plane and make the daughter cells genetically different from the original one.

The Chiasma is the position where two homologous chromatids interchange genetic information, giving a place for new genetic material or information to be provided to descendants.

After crossing over, homologous chromosomes get separated again.

In the attached imaged there are four different stages of meiosis.

Stage C is the one that contributes the most to diversity.

We can see that crossing over has already occurred between homologous chromosomes, and they have already interchanged segments.

In the image you will see the difference between chromosomes that has gone through the crossing over mechanism, and chromosomes that has not. The difference in color represents segments interchange and variation.

Why are carbon dioxide concentrations expected to increase?

SVETLANKA909090 [29]

Carbon dioxide concentrations are expected to increase, because fossil fuel burning is expected to increase, because of an increase in agriculture and because more land will have to be cleared for increasing populations and agricultural use.

If you walk at 3 mph, how many miles would you have to walk to “burn off” 4 slices of pepperoni pizza (181 Calories each)?

Anestetic [448]

Normally, it would take approximately 59 minutes to burn off a slice of peperoni pizza. Most of us walk roughly three miles per hour. So, to burn the calories found in just one slice of peperoni pizza, we have to walk about three miles. Therefore, to burn off 4 slices of peperoni pizza, we need to walk approximately 12 miles.
