Answer:
The fertilized egg stays in the fallopian tube for about 3 to 4 days. But within 24 hours of being fertilized, it starts dividing fast into many cells. It keeps dividing as it moves slowly through the fallopian tube to the uterus. Its next job is to attach to the lining of uterus.

Answer:
Which of the following is not part of the nucleotide structure?
a.
<h2>
Sulfate backbone </h2>
c.
Phosphate group
b.
Nitrogenous base
d.
5-carbon sugar
Explanation:
A nucleotide is an organic molecule that is the building block of DNA and RNA. ... A nucleotide is made up of three parts: a phosphate group, a 5-carbon sugar, and a nitrogenous base. The four nitrogenous bases in DNA are adenine, cytosine, guanine, and thymine. RNA contains uracil, instead of thymine.
A microorganism (or microbe) is any microscopic living organism or virus, that is too small to see with the unaided human eye without magnification. Microorganisms are very diverse. They can be single-celled or multicellular and include bacteria, archaea, viruses and most protozoa, as well as some fungi, algae, and animals, such as rotifers and copepods. Many macroscopic animals and plants have microscopic juvenile stages. Some microbiologists also classify biologically active entities such as viruses and viroids as microorganisms, but others consider these as non-living.
Natural selection relates to adaptations except for Natural selection grants a species any trait it might need for survival
Explanation:
The ways in which an organism adapt to its changing environment is termed as natural selection. The individual with better trait compatible to the environment adapt themselves and reproduce to pass on the useful trait to its offspring. Through the process of natural selection, population survives.
Natural selection is also responsible for speciation where new species can occur in population.
If the environment changes rapidly, some of the species are not able to adapt
and eventually gets deleted from the environment.
Natural selection itself does not provide any trait to the species or population it is just a way how species adapt with traits they inherited over a period of time.
