A cell moves particles from a region of lesser concentration to a region of greater
concentration by
1)facilitated diffusion
2)passive transport
3)osmosis
4) active transport

Answers

Answer:

facilitated diffusion

Explanation:

Best if luck pal

A cell moves particles from a region of lesser concentration to a region of greater concentration by Facilitated Diffusion.

Facilitated Diffusion in the cell body is the passive movement of particles  across a plasma membrane from a region of higher concentration to a region of lower concentration

Examples of biological processes that undergo  facilitated diffusion are

The movement of glucose and amino acid into the cell from the bloodstream.The transport of carbon dioxide(gas )from the lungsion transport.

HELP!! Which of the following is NOT true of protein structure?
A: Proteins' secondary structure is dictated by peptide bonds.

B: Proteins' tertiary structure is dictated by R group bonds.

C: Proteins have quaternary structure when they are arranged together.

Answers

The statement that is not true related to the protein structure is option b.  Proteins' tertiary structure is dictated by R group bonds.

What is protein structure?

It is classified as the  three dimensional shape of the protein.

In the tertiary structure it does contain the  single polypeptide chain that we called as the backbone or there more than one protein secondary structures

Also, it should not be dictated by R group bonds.

Therefore, we can conclude that the option b is correct.

Answer:  A)

Explanation:

Widow's peak is a dominant trait (W). Tongue-rolling is a dominant trait (T). Two people who are heterozygous for both traits (widow's peak, tong-roller) get married and have children. Complete the Punnett square to show the parents the probabilities for each child, then answer the question that follows.
What is the probability that the parents will have a child without a widow's peak and unable to roll his tongue?

1/16

Answers

Answer:

The correct answers are -

A. 1)  WWTt    2) WWTt   3)WwTt   4)wwTT

B. 1/16

Explanation:

We know that each gene have minimum two alleles or forms of the gene one is dominant and the other is recessive. So, it is given that W is dominant trait that represents widow's peak so the recessive allele would be w, similarly for the tongue-rolling trait dominant is T n recessive would be t.

So the dihybrid cross of heterozygous parents for both is shown in the punnet square given which lack few possibilities that can easily be carried out by the gametes mention there that are

1. WWTt  by WT and Wt gamets

2. WWTt  by WT and Wt

3)WwTt   by Wt and wT

4)wwTT by wT and wT

And the possibility of a child without a widow's peak and unable to roll his tongue would be possible only if the alleles are recessive for the both trait which is one out of 16 in punnet square thus the possibility would be - 1/16
