1. If the DNA is carrying a silent mutation, what will be the impact it will have on the organism?

antiseptic1488 [7]

The DNA carrying a silent mutation will have no gene expression or result on the phenotype or physical appearance of the organism. Silent mutations code for the same amino acid resulting in more genetic diversity, having a genotypic advantage, but providing no noticeable differences.

Which of the following statements best describes why Lamarck's theory of evolution was incorrect AND why Darwin's theory of evol

kupik [55]

Answer:

Explanation:

Lamarck's theory basically says that traits that are developed over time can be passed on (Theory of Inheritance of Acquired Characteristics), which is incorrect. Darwin is correct that only traits possessed at birth can be passed on.

Explain how ATP stores and releases energy

atroni [7]

Answer:

The ATP molecule can store energy in the form of a high energy phosphate bond joining the terminal phosphate group to the rest of the molecule. In this form, energy can be stored at one location, then moved from one part of the cell to another, where it can be released to drive other biochemical reactions.

In a process called cellular respiration, chemical energy in food is converted into chemical energy that the cell can use, and stores it in molecules of ATP. ... When the cell needs energy to do work, ATP loses its 3rd phosphate group, releasing energy stored in the bond that the cell can use to do work.

In chemistry class we learn the rule "like dissolves like" when studying why polar substances dissolve in each other (like sucro

Lyrx [107]

<h2>The correct answer is: d.</h2>

Explanation:

As per the question, the correct answer is to be chosen from the given options that is identical to the logic given in the statement of the question that is, "like dissolves like".
Polar molecules can get dissolved in water because they are hydrophilic or water-loving in nature. They have such functional groups in their structure which have the capability of forming hydrogen bonds with water molecules, hence get dissolved in water.
Non-polar molecules can get dissolved in non-polar solvents like fats and oils because either of them are hydrophobic or water-hating in nature. They have such functional groups which can form hydrophobic and Van-der-Waal's forces of interaction with each other , hence they get dissolved in non-polar solvents.
Polar and non-polar substances are unable to get dissolved in each other because the polar molecules are incapable forming hydrophobic or Van-der-Waals forces of interaction with the non-polar molecules and the non-polar molecules are incapable of forming hydrogen bonding with the polar molecules.
Trans-membrane proteins are those which remain integrated in the lipid bilayer of the plasma membrane and spans across the membrane forming a connection between the cell interior and the cell exterior.
They are required for transporting small polar molecules and ions across the plasma membrane.
The lipid bilayer of the plasma membrane is otherwise impermeable to the movement of polar molecules and ions due to the hydrophobicity of the lipid molecules.
The trans-membrane proteins are amphipathic molecules, that is, they are made up of both polar and non-polar amino acid residues.
These amino acid residues are such arranged in the structure of the proteins that the non-polar amino acids face towards the lipid molecules in the bilayer thereby forming hydrophobic and Van-der-Waals forces of interaction with the lipid molecules.
The polar amino acids face towards the channel or lumen formed by the protein across the lipid bilayer so that they can form hydrogen bonds with the polar molecules and ions which are transported across the plasma membrane.
Hence, like interacts with like.
