Aleksandr-060686 [28]3 years ago
3 0

Answer:

Hydrogen bond

Explanation:    

The α-helix and the β-pleated sheet are secondary protein structures. They are formed within a polypeptide due to interactions between the atoms of the backbone.

Both the alpha helix and beta pleated sheets are held in shape(stabilized) by hydrogen bonds which form between the carbonyl (C= O)of one Amino acid and amino(N-H) of another amino acid.  

This bonding is gives them their structure.

The endoplasmic reticulum (particularly the rough endoplasmic reticulum) has ribosomes attached to it, a type of organelle that synthesizes protein. It also itself folds proteins in sacs on its surface called cisternae.

The question, however, most likely is referring specifically to ribosomes, as these are the organelles primarily responsible for the production of proteins. The endoplasmic reticulum is mostly to assist the ribosomes and transport the proteins once they are properly folded.

Plasmids are typically transferred among members of a bacterial community by ________ gene transfer.
disa [49]

Answer:

Horizontal

Explanation:

Horizontal gene transfer may be defined as the transfer of the genetic material from the parents to their offspring. Three main methods of horizontal gene transfer are conjugation, transformation and transduction.

The transfer of plasmid among the members of bacterial community mainly occur by the horizontal gene transfer. This transfer of genetic material allows the bacteria to withstand at extreme conditions, confer antiobiotic resistance and increase their chance of survival in the environment.

Thus, the answer is horizontal gene transfer.

Cite an example to explain why species interactions are conditional and dynamic
Zielflug [23.3K]
Mutualism is a way of life in which two species that could live independently come together permanently or sporadically and each one puts something on their side for the survival of both. In nature there are many types of mutualism, for example, the spider and the toad, the narrow-billed toad is an ally of a type of tarantula that usually devours small frogs, but what, in exchange for this small amphibian to eat the parasites that affect its eggs, the arachnid allows it to live in his burrow underground and in return defends him from possible predators, like owls, throwing to them urticating hairs in their eyes.
