Amongst these terms the one which response best to the reaction of plant towards touch is the thigmotrophism

<u>Explanation:</u>

The thigmotrophism is a mechanism through which the plant responds towards some touch stimulus, this can be greatly observed in group plants that touch each other while growing.

The positive thigmotrophism is a concept of the plant getting benefitted and growing towards the touch stimulus and the negative thismotrophism is the response of the plant to move away from the touch stimulus.

Why might a scientist want to disrupt the plasma membrane and how might they do this experimentally?
kupik [55]

It is possible to disrupt the plasma membrane by using enzymes and/or detergent agents.

<h3>What is the plasma membrane?</h3>

The plasma membrane is a lipid bilayer that is mainly composed of phospholipids and cholesterol.

In laboratory conditions, it is possible to disrupt this lipid bilayer by using detergent and proteins (enzymes) that break the bonds binding phospholipids.

For example, enzymes can break down the double bonds that bind fatty acids in the lipid bilayer.

In conclusion, the plasma membrane can be break down by applying enzymes and detergents.

Which of the following sequences shows a frameshift mutation compared to the wild-type mRNA sequence?
Butoxors [25]

Option C:

B. wild-type 5-AUGCAUACAUUGGAGUGA-3 mutant 5'-AUGCAUACAUCUGGAGUGA- 3' 

Explanation:

A frameshift mutation is a genetic mutation such that the triplet nature of gene expression by codons, the insertion or deletion occurs in such as way that it alters the complete sequence of 3 codon sets and can change the reading frame, resulting in a completely different translation from the original.

As it is pertinent to understanding that all genes are normally translated in sets of 3 codons, which typically describes and explain a unique amino acid sequence. Thus, if a frame shift mutation occurs, it can affect many amino acid sequences and finally the entire protein.  

If we look at option B:

wild-type 5-AUG   CAU  ACA  UUG  GAG  UGA-3  

mutant 5’-    AUG   CAU  ACA  UCU  GGA  GUG  A-3’  

An insertion of a base Uracil showed at the end of 3rd codon which affected and altered the whole sequence of codon triplets. This changed all next codons and finally all next amino acids will be altered.

This is for Forensics<br><br>What is the difference between sand, silt, and clay?​
KIM [24]

Answer:

They main difference is in chemical composition and particle size. Silt is composed of silicate minerals, or those containing silicon and oxygen. Clay is composed of metal silicates, or silicates with metals like magnesium or aluminum associated with it.Clay particles are extremely fine — smaller than 0.002 mm. Sand particles are 2.00 to 0.05 mm in diameter

Explanation: Basically, the main difference is their size.
