Answer: Platelets release a vasoconstricting substance called <u>SEROTONIN.</u>
If you are asking if that is true or false, it is false because all fungus like protists are heterotrophs, not autotrophs
The prefix "poly-" means "more than one" and the suffix "-spermy" is clearly related to sperm. Accordingly, polyspermy is when more than one sperm fertilizes an egg, something that organisms try to avoid.
To avoid this extra fertilization, specific organisms can use "electrical polyspermy blocks" (the fast process), which changes the negative electrical charge of the egg to positive, thus repelling the also positively charged sperm. The slower prevention process is when an organism undergoes a secretion reaction, or a cortisol reaction, which contributes to envelopping the egg by changing its membrane.
If lions attack the slowest animal in a herd, it is beneficial to the herd in the following ways:
1.) Evolutionarily, the faster herd members survive and breed, increasing the speed of the offspring and guaranteeing better survival for the future population.
2.) The lions focus on the straggling animal, allowing the rest of the herd to escape.
3.) The death of one herd member ensures the survival of many more.
