Smoking ruins your lungs making it harder to breath and get oxygen
you need oxygen when you exercise so you don't faint
smokers get less so it is harder for them, its like trying to exercise while breathing through a sponge or a straw os
Bones
hope u love my answer baby kiss kiss
Answer:
1)
- frequencies of light-colored mice ≅ 0.74
- frequencies of dark-colored mice ≅ 0.26
2)
- frequencies of light-colored mice ≅ 0.13
- frequencies of dark-colored mice ≅ 0.87
3)
- q² = 0.74
- p² = 0.02
- 2pq = 0.24
4)
- q² = 0.13
- p² = 0.4
- 2pq = 0.46
5)
The dark-colored fur seems to have the greatest overall selective advantage
6)
Dark lava, that changed the color of the substrate, from light to dark.
7)
Because to produce dark color, animals from the different regions suffered different mutations that drove them to have almost the same dark fur color. All of the animals are inhabiting dark substrate, which means that this environmental condition is favoring the same phenotype.
8)
To see if the mice population is evolving, you need to take a sample of animals per year, through many years, and analyze if it is changing or not. If the population is evolving, you will notice a change in the allelic and genotypic frequencies over the years, favoring one genotype or the other. If the population is not evolving, the frequencies will keep equal through the years, it will not change.
Explanation:
Due to technical problems, you will find the complete explanation in the attached files.
Lthough much of the explanation for why certain substances mix and form
solutions and why others do not is beyond the scope of this class, we
can get a glimpse at why solutions form by taking a look at the
process by which ethanol, C2H5OH, dissolves in
water. Ethanol is actually miscible in water, which means that the two
liquids can be mixed in any proportion without any limit to their
solubility. Much of what we now know about the tendency of particles
to become more dispersed can be used to understand this kind of change
as well.
Picture a layer of ethanol being carefully added to the top of some water (Figure below).
Because the particles of a liquid are moving constantly, some of the
ethanol particles at the boundary between the two liquids will
immediately move into the water, and some of the water molecules will
move into the ethanol. In this process, water-water and
ethanol-ethanol attractions are broken and ethanol-water attractions
are formed. Because both the ethanol and the water are molecular
substances with O−H bonds, the attractions broken between water
molecules and the attractions broken between ethanol molecules are
hydrogen bonds. The attractions that form between the ethanol and
water molecules are also hydrogen bonds (Figure below). There you go
