PLEASE HELP 40 POINTSSSS. Woolly mammoths became extinct around 10,000 million years ago. A recent study conducted by scientists

found that the last generations of woolly mammoths were plagued by harmful gene mutations. Some of the mutations caused them to have softer fur that didn’t protect them from the cold, a diminished sense of smell, and digestive problems. A species potential for evolution is based on four factors: the potential for a species to increase in number the heritable genetic variation of individuals in a species due to mutation and sexual reproduction organisms competing for limited resources such as food or water in their environment the proliferation of those organisms that are better able to survive and reproduce in the environment In two to three paragraphs, explain why the last generations of woolly mammoths couldn’t meet these factors to evolve in a changing environment. Also explain how data such as the fossil record and DNA evidence can identify the factors that can lead to the evolution of a species.

Explain the process of evolution through isolation that results in speciation
ICE Princess25 [194]

Process of population occurs when allele frequency in a population may change due to fundamental forces of evolution.

For example natural selection, genetic drift, gene flow and mutation. This process takes place when new traits transfers genes between populations for example between species or in migration.

Speciation of population to separate species will take forms like sympatric and allopatric. In allopatric is where a physical barrier is been able to separate population why sympatric the population which is sharing the geographical location is formed by environment factors to separate.

If they are separated post zygotic or prezygotic between species.

What is an important safety consideration when hunting from a ground blind?
Grace [21]
Ground blinds should always be located:
Downwind or crosswind of the spot where you expect to see your quarry because your scent will be carried at ground level and downwind of your blind
Away from the sun
Where the foreground and background are safest

Scientists have noticed that the entire DNA molecule has the same width, despite the fact that the four nucleotides are NOT the
const2013 [10]

I don't have access to your model, although I'm sure it's beautiful. Fortunately, this question can be answered without one.

A strand of DNA is a polymer consisting of monomeric nucleotide units. The nucleotides that are found in DNA are distinguished by their nucleobases: adenine (A), thymine (T), guanine (G), and cytosine (C). Each nucleotide in DNA is made up of a single nucleobase, a sugar (deoxyribose), and a phosphate group. These nucleotides form extremely long chains comprising phosphate-sugar linkages (covalent, phosphodiester bonds).

In native, double-stranded DNA, you have of these chains (or strands) arranged side-by-side such that the nucleobases on one chain are faced directly across <em>corresponding nucleobases </em>on the other chain, which enables hydrogen bonding between the bases.

There is a "rule" regarding which bases form hydrogen bonds with one another (Chargaff's rule): adenine with thymine and guanine with cytosine.

What does this have to do with the width of the DNA molecule?

The four nucleotides can be structurally classified into two categories: pyrimidines and purines. For our purposes, we only need to know that pyrimidines are six-membered rings and purines are a fusion of a six- and five-membered ring (basically, purines are pyrimidines attached to a five-membered ring). Thymine and cytosine are pyrimidines, and adenine and guanine are purines.

So, geometrically, adenine and guanine are larger (and, thus, "wider") than thymine and cytosine since adenine and guanine contain an extra ring. But remember our base-pairing rules: In native DNA, adenine (two rings) on one strand pairs up with thymine (one ring) on the other strand, and guanine (two rings) pairs up with cytosine (one ring) on the other strand.

Because there's a 1:1 ratio between A:T and G:C in double-stranded DNA, the DNA molecule consists of complementary base pairs that, in any given composition of, has equivalent widths. Put simply, the A=T pair has the same width as a G≡C pair because both base pairs are between one pyrimidine and one purine.
