Four general conditions necessary for natural selection to occur are: A. More organisms are born than can survive. B. Organisms vary in their characteristics, even within a species. D. Differences in reproduction and survival are due to variation among organisms.
Hope this helps.
The questions can you ask, and then investigate, to help determine the evolutionary relationship among the trout species are about the evolutionary changes.
<h3>
What kind of evolution is processing?</h3>
The evolution of various organisms from a not unusual place ancester took place thru the mechanisms like gene duplication, gene amplification, and mutations. Accumulation of mutations gives insights at the phylogenetic evaluation of organisms.
- From the given data, it could be stated that rainbow trout and brown trout have a current not unusual place ancestor. The species are carefully associated, and feature different very lately in phrases of evolution.
- However, the not unusualplace ancestor for not unusualplace carp and the opposite carps had different lengthy before, sufficient to build up enough mutations and display substantial version withinside the genotype of the chosen region.

<span>tree and nest
If a robin builds a nest in a big tree, the robin benefits and the tree
is not helped or harmed. This type of symbiotic relationship is called
commensalism, and it is between the tree and the nest/Robin.
<span>There
are several types of biotic relationships that is occurring every
single moment in the ecosystem and commensalism is one. In contrast,
parasitism is the biotic relationship where one organism doesn't benefit
from the other and is harmed. In this scenario with human beings and
mosquitos, this phenomenon of interaction is distinguished as parasitism
where mosquitos draws blood that contains nutrients from the human
tissue to use it as its source of food and then leaves harmful
substances and bacteria in the human’s blood stream.<span> </span></span></span>
