Forward primer: 5'-AGTCTACTCGTAACCGGTTACC-3' Reverse primer: 5'-TAAGGCATCATGGTAACCGGTT-3' The two primers above have the melting

Jobisdone [24]

Answer:

B

Explanation:

The 3'-end of the reverse primer (3'-TTGGCCAATGG---5') is complementary to the forward primer (5'---AACCGGTTACC-3') and thus reduces the ability of the primers to bind to the targeted DNA sequence. There is possibility of hairpin loop formation or primer dimmers formation

The evolutionary history for a group of species is called a

blsea [12.9K]

Answer:

The evolutionary history for a group of species is called a <u>phylogeny.</u>

Explanation:

Phylogeny is defined as the evolutionary history or evolutionary chronicle of the species, that is, it studies the relationship deals with the relationship between members of a group of species from the morphological, anatomical and embryological point of view. In this way, phylogeny explains the chronicle of each species, the different bifurcations, families and genetic structures, focusing on the evolution of the species in a global way.

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.
