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.
<h2>Energy </h2>
Explanation:
Energy flows in only one direction through an ecosystem
- The Sun supports most of Earth's ecosystems
- Plants create chemical energy from abiotic factors that include solar energy and chemosynthesizing bacteria create usable chemical energy from unusable chemical energy
- The food energy created by producers is passed to consumers, scavengers, and decomposers
- Energy flows through an ecosystem in only one direction, it is passed from organisms at one trophic level or energy level to organisms in the next trophic level
- Most of the energy at a trophic level – about 90% – is used at that trophic level and organisms need it for growth, locomotion, heating themselves, and reproduction
- So animals at the second trophic level have only about 10% as much energy available to them as do organisms at the first trophic level
- Animals at the third level have only 10% as much available to them as those at the second level
Everything in Earth's system can be placed into one of four major subsystems: land, water, living things, or air. These four subsystems are called “spheres.” Specifically, they are the lithosphere (land), hydrosphere (water), biosphere (living things), and atmosphere (air)...
I hope this helps you with biology...

The cell needs transcription because the DNA cannot leave the nucleus and therefore cannot transmit info to the other cells.
