There are 3 types of mutations, base substitutions - single base mutations are called point mutations. Point mutations are the most common type of mutation and there are two other types. point mutations occur in DNA sequence seconding proteins are either silent, missense or nonsense. Deletions is the second type of mutation, this results when one or more base pairs are lost from the DNA. If one or two based are deleted the translation frame is altered resulting in a garbled message and nonfunctional product. A deletion of three or more bases leave the reading frame intact. A deletion of one or more corona result in a protein missing or more amino acids. this may be deletions or not. And lastly insertions this is when you have additional base pairs which may lead to frameshifts depending on whether or not multiples or three base pairs are inserted. combinations of insertions and deletions leading to a variety of outcomes are also possible.

Answer:

Explanation:

Un cambio en la secuencia de bases en el ADN o ARN se conoce como mutación . ¿La palabra mutación te hace pensar en ciencia ficción y monstruos con ojos de insecto? Piensa de nuevo. Todos tienen mutaciones. De hecho, la mayoría de las personas tienen decenas o hasta cientos de mutaciones en su ADN. Las mutaciones son esenciales para que ocurra la evolución. Son la fuente principal de todo el material genético nuevo -nuevos alelos - en una especie. Aunque la mayoría de las mutaciones no tienen efectos en los organismos en que ocurren, algunas mutaciones son beneficiosas. Incluso las mutaciones dañinas rara vez causan cambios drásticos en los organismos.

Which of these choices is an advantage of the Endangered Species Act?
Sindrei [870]

The correct answer is option C, that is, saves species from extinction.  

The Endangered Species Act is one of the most essential and efficient environmental laws of America. It signifies a willingness by the people of America to work in harmony and restore and protect the species most vulnerable of getting disappeared forever.  

The act offers common sense, balanced solutions for the landowners, government agencies, and concerned citizens to preserve the endangered wildlife and their habitats. It includes three prime elements:  

1. Inhibiting the listed species from getting harmed or killed

2. Developing plans to restore healthy populations

3. Safeguarding habitat important to these species survival.

Molodets [167]

Answer:

2.glucose move into chamber B faster than fructose

Explanation:  

  • Facilitated diffusion: refers to the transport of hydrophilic molecules that are not able to freely cross the membrane. Channel protein and many carrier proteins are in charge of this <u>passive transport</u>. If uncharged molecules need to be carried <u>this process depends on concentration gradients</u> and molecules are transported from a higher concentration side to a lower concentration side. If ions need to be transported this process depends on an electrochemical gradient. The glucose is an example of a hydrophilic protein that gets into the cell by facilitated diffusion.  Facilitated diffusion is a passive transport process because the cell does not need any energy to make it happen.  

The exposed scenario is an example of facilitated diffusion, a process that occurs in favor of the concentration gradient, and which rate depends on the concentration of molecules in each side of the membrane, in this case, glucose and fructose, among other factors that might also influence the diffusion rate. So, as the concentration of glucose is higher in chamber A (80%), and lower in chamber B (20%), in comparison with fructose, the first one will diffuse faster than fructose. The difference in concentration between both chambers is sharper in glucose, so its transport is faster than the fructose transport, which will also diffuse but at a lower rate.
