This flowering plant does not wilt but stands straight up, reaching toward the sunlight, because its cells contain mostly:

Have a BEAUTIFUL day~
The genetic variations seen in and between populations are known as human genetic variation.
Humans differ genetically from one another. Due to developmental mutations and gene copy-number variation, even monozygotic twins, who arise from a single zygote, may differ genetically. Techniques like genetic fingerprinting rely on individual differences, even between closely related people.
There are 324 million identified variations from sequenced human genomes as of 2017.
A person's genome typically differs from the reference genome by 20 million base pairs, or 0.6% of the total 3.2 billion base pairs, as of 2015.
In contrast to other species, humans are genetically uniform. While a limited number of genetic variations are found more commonly in particular geographic regions or in individuals with ancestry from those places, this variance accounts for the majority of genetic variation.
Genetic variation between populations occurs for at least three reasons. If an allele offers a competitive advantage, natural selection may endow people with an adaptive advantage in a particular environment.

Answer:
that's an pretty interesting question
Explanation:
For the simple reason that no digestion takes place in the human intestines. Digestion takes place in the stomach. Intestines are where the nutrients are absorbed into the body, and the conditions there are much more favourable for parasites like tapeworms. The stomach produces hydrochloric acid strong enough to burn a hole in a rug and is also home to lot of other strong digestive enzymes. Any tapeworm venturing there would get digested in seconds.
23 pairs or 46 individual chromosomes
Any form of precipitation, including rain, snow, hail, fog, or dew, that is high in acid pollutants, especially sulfuric and nitric acid. Acid precipitation has a pH of less than 5.6 (the normal acidity of unpolluted atmospheric water) and is often less than pH 5.0.
Air pollution can kill trees and can cause chronic disease
