Disparities in mate attraction that alone account for differences in reproductive success An important aspect of evolutionary biology is sexual selection. The nature and scope of sexual selection, however, have been debatable since Darwin first proposed the idea of it.
Recent debate has brought the fundamental topic of what sexual selection actually is back into focus. Incorporating female-female reproductive rivalry into sexual or natural selection is one example of this.
Sex roles are determined by differences in gametes: men generate significantly more plentiful, smaller, motile gametes whereas females produce relatively fewer, more nutritious, often non-motile gametes. There will be an excess of male gametes that will not fertilize any eggs since just one gamete of each kind is necessary to generate a child.

Answer:
561
Explanation:
This is math so I got you.
This is just going to subtract 12 from 55 since we don't now when during her 12th year of age she started or when during her 55th year f age she ended.
55 - 12 = 43, so about 43 years. Also not going to account for leap years. So we are just going to say each year had 365 days. so 43 years and 365 days per year = 15695 days.
If her cycles were each about 28 days we divide the total number of days by 28 and that tells us about how many cycles there were.
15,695 / 28 = 560.5 which I will round to 561
561 cycles means 561 eggs if my biology knowledge is as accurate as I think it is.
Answer:
What do they look like?
Glaciers look like solid blocks of ice.
What climate do they exist in?
Regions that have high snowfall in winter and cool temperatures in summer.
Where can you find them?
Most of the world's glacial ice is found in Antarctica and Greenland, but glaciers are found on nearly every continent, even Africa.
What do you think we can learn from glaciers?
Glaciers preserve bits of atmosphere from thousands of years ago in these tiny air bubbles, or, deeper within the core, trapped within the ice itself. This is one way scientists know that there have been several Ice Ages. Scientists are also finding that glaciers reveal clues about global warming.
(The last question is unclear to me, so I'm going to take a guess as to what you meant)
Why is sea ice so important?
Arctic sea ice keeps the polar regions cool and helps moderate global climate.
I hope this helps!! :3

Honestly my man, I can not do this math problem and hope you find your help. KhanAcademy always helps me when noone else can
<span>The two sentences that accurately describe the girls' experience with heat transfer are "Camille heats a rock in the campfire for 30 minutes, and then removes it with tongs. She greases the rock and lays the bacon strips directly on it." By heating the rocks in the campfire and laying the bacon on the rocks, the girls transferred the heat from the fire to the rocks, and the heat from the rocks to cook the bacon.</span>
