The outer cells of a blatocyst become the <u>placenta</u>, an organ that offers protection and nourishment.
Placenta, aka afterbirth, is an organ found in a female body that forms around the baby in order to protect and feed it. It provides nourishment for the fetus, keeps it warm, eliminates any infections that may occur, and overall protects the developing baby.
Answer;
D. Most of the energy from photosynthesis flows out as heat
Explanation;
Energy flow is the amount of energy that moves through a food chain in a given ecosystem.
Producers such as green plants in a ecosystem convert energy from the the sun into carbon bonds, such as those found in the sugar glucose through the process of photosynthesis.
The amount of chemical energy storied as nutrients in the bodies and wastes of organisms flows through ecosystems from one trophic level to the next and through this flow energy also is lost as heat. And the chemical energy available to the succeeding feeding level decreases.
Polyester
Polyesters are naturally occurring chemicals and a synthetic polymer (plastic) produced by mixing ethylene glycol and terephthalic acid. Polyester is any fabric which is produced from polyester yarns or fibers and is highly used in clothing. Polyester fabric has great washing ability, dries quickly, resist wrinkling, and is resistant to many chemicals.
Disregarding data that does not fit with your personal expectations
It is the only answer choice that involves the scientist behaving in a way that could lead to the results of the experiment to be skewed
I'm think the predators increase as well, the ones that eat the moths anyway due to the increase.
