Cod fry often settle under the bell of some jellyfish species, whose tentacles are poisonous. Name the form of relationship illu

bixtya [17]

Answer:

Explanation:

해파리 (cnidarians) have a worldwide distribution. Despite most being harmless, some species may cause local and also systemic reactions. 처치 of 해파리 envenomation is directed at: alleviating the local effects of venom, preventing further nematocyst discharges and controlling systemic reactions, including shock. In severe cases, the most important step is stabilizing and maintaining vital functions. With some 차이점 between species, there seems to be evidence and consensus on oral/topical analgesics, hot water and ice packs as effective painkillers and on 30 s application of domestic vinegar (4%–6% acetic acid) to prevent further discharge of unfired nematocysts remaining on the skin. Conversely, alcohol, methylated spirits and fresh water should be 조심스럽게 avoided, since they could massively discharge nematocysts; pressure immobilization bandaging should also be avoided, as laboratory studies show that it stimulates additional venom discharge from nematocysts. Most 처치 approaches are presently founded on 상대적으로 weak evidence; therefore, further research (especially randomized clinical trials) is strongly recommended. Dissemination of appropriate 처치 modalities should be deployed to better inform and educate those at risk. Adequate signage should be placed at 바닷가 to notify tourists of the jellyfish risk. Swimmers in risky areas should wear 보호 장비.

Environmental factors can influence natural selection because they can increase or decrease

olchik [2.2K]

Answer:

Environmental factors can influence natural selection because they can increase or decrease the amount of genetic variation in a population.

Explanation:

Natural selection is a process that involves the survival of species through changes in the expression of their genes, making possible the process of adaptation to environmental changes. It is one of the explanations for the biological evolution of species.

The second premise, necessary for natural selection to be possible, implies the existence of a variability (genetics) of traits among individuals in a population.

The other premises of natural selection are the faculty of traits to be inheritable and that genetic variability should lead to reproductive success and survival.

<em>The other options are not related to the process of natural selection, since it is not possible for natural selection to increase or decrease the number of chromosomes, in addition to the fact that genetic variability must be observed in a population, not in a single individual, to be considered natural selection </em>
