Answer:
Mutualism is a symbiotic relationship in which both species benefit. Commensalism is a symbiotic relationship in which one species benefits while the other species is not affected. Parasitism is a symbiotic relationship in which one species (the parasite) benefits while the other species (the host) is harmed.
Answer:
See explanation below
Explanation:
<em>Non-disjunction occur as a result of lack of separation of homologous chromosomes during meiosis. </em>
As a result, the gametes (the daughter cells formed) produced end up having extra or lesser chromosomes as compared to a normal gamete.
When a gamete with extra chromosome fertilizes a normal gamete, the resulting offspring will have an extra chromosome (trisomy condition).
On the other hand, when a gamete with one less chromosome than normal fertilizes a normal gamete, the resulting offspring will have one less chromosome than normal offspring (monosomy condition).
Assuming a chromosome with Aa gene undergoes non disjunction during meiosis, the resulting gametes either contain both A and a chromosome or contain no chromosome at all.
If Aa gamete is fertilized by a normal haploid sperm (a), the resulting zygote will have the genotype Aaa.
If a gamete with no chromosome at all fertilizes a normal haploid sperm, the resulting offspring will have the genotype a.
Answer:
an independent variable is a variable that changes an a dependent variable is something that doesn't change
Explanation:
like if i put two fish is different size tanks and measured them after so long
measuring them would be dependent and putting them in different size tanks would be independent
Answer:
Ocean currents act as conveyer belts of warm and cold water, sending heat toward the polar regions and helping tropical areas cool off, thus influencing both weather and climate.
Explanation:
So that is why.
<span>Vitalism is a belief that there is difference between living and noliving things. Living things are governed by different principles which are not applicable for nonliving things. The scientist now reject the vitalism since it lack scientific proof. It is considered only as spiritual. modern scientist believe life originated from non living things in the course of time.</span>
