Solution:
A peptide bond is a chemical bond formed between two molecules when the carboxyl group of one molecule reacts with the amino group of the other molecule, releasing a molecule of water (H2O). This is a dehydration synthesis reaction (also known as a condensation reaction), and usually occurs between amino acids.
Thus the required right answer is carboxyl group and other molecule.
Answer:
They are about the same size and have about the same mass.
Explanation:
Basically both planets are about the same size therefore that is why Venus is called Earth's twin.
Genetic engineering is the process of manually adding new DNA or genetic material to an organism. The latest example of genetic engineering is immunotherapy. Healthy white blood cells are genetically modified to target a specific type of cancer. These modified cells are then injected into a person with this specific type of cancer. These cells then target the cancer cells and destroy them. This immunotherapy is more advanced than Chemotherapy as it only targets the rogue cells, not all the cells.
Answer:
<h2>Only first 1 requires energy, rest all are passive transports!!</h2>
Explanation:
<h3>First one:</h3>
Here the molecules are moving from region of low concentration to high concentration, so as it is an uphill transport also known as Active transport. So active transport requires the ATP to be carried out.
<h3 /><h3>Second one:</h3>
This is the normal passive transport of hydrophobic or lipid soluble substances. So as normal passive transport requires no energy but a concentration gradient. So it doesn't require the ATP to be carried out.
<h3>Third one:</h3>
This is a transport system of protozoans like Amoeba which form a pseudopodia process around the food, and then engulf the substances which then is surrounded by vacoule for digestion to take place. It also doesn't require energy.
<h3>Fourth one:</h3>
This is an example of bulk transport mechanism where large big molecules move from higher concentration to their lower concentration through special membrane proteins and then their utilisation takes place. This is also known as Endocytosis. This also doesn't require energy to be carried out.
