Answer:
Homeostasis is the state of steady internal, physical, and chemical conditions maintained by living systems
Explanation:
(A property of cells, tissues, and organisms that allows the maintenance and regulation of the stability and constancy needed to function properly)
Answer:
A. The ecosystem can support fewer foxes than grasshoppers.
Explanation:
Since the energy has to transfer from organism to organism, it reduces in amount. Since there are more grasshoppers than foxes, than the ecosystem can support grasshoppers easily.
The first one SUBLIMATION. :)
Monoploid organisms reproduce asexually since they need to transmit all of their genetic material to their offspring. Diploid organisms, have 2 copies of their genetic material that differ slightly in their genes. Since the progeny gets half of the DNA from each parent, we have that new combinations can emerge; for example, if the mother is AA for some allele and the father aa, their offspring will be Aa, a new genotype. This might have different implications (for example, the recessive gene for thalassemia also provides resistance to malaria). Finally, during meiosis, there is also an event called crossover that increases the genetic variation of the offspring.
<span>The formation of the fertilization envelope (slow-block to polyspermy) requires an increase in the availability of </span>calcium ions.
Slow-block to polyspermy is also called cortical reaction. In this reaction, the sperm will be permanently blocked by cortical granules. The release of calcium ion will trigger this reaction.
