Answer:
The correct answer is osmosis is the movement of water across the membrane;diffusion is the movement of molecules from a higher to lower concentration with or without the presence of membrane.
Explanation:
Diffusion and osmosis are the two most important process of passive transport.Both diffusion and osmosis helps in the movement of water molecules from high water concentration region to region of low water concentration until equilibrium in both sides is reached.
Osmosis needs the presence of a semipermeable membrane to occur.
Answer:
It connects amino acids.
Explanation:
The process of synthesis of proteins is known as Translation. The process takes place inside the ribosome and involves tRNA and codons. The proteins are synthesised in their linear form which is composed of monomer units called amino acids.
The amino acids are therefore known as the building blocks of the proteins. These amino acids possess a carboxyl group (-COOH ), an amine group (- NH₂) and -R group.
A bond is formed between -COOH and -NH₂ in the amino acids which links the two amino acids together releasing a molecule of -H₂O, therefore, called dehydration method. This bond is known as a peptide bond which is involved in the formation of amino acid.
Thus, the selected option is the correct answer.
Answer:
Evolution is not the same as adaptation or natural selection. Natural selection is a mechanism, or cause, of evolution. Adaptations are physical or behavioral traits that make an organism better suited to its environment. Heritable variation comes from random mutations.
Explanation:
Answer:
Even primitive cells, like the prokaryote, can carry out the functions of life.
Explanation:
Most multicellular organisms are eukaryotes, like you and me. Generally, the one-celled organisms can be either. But, even the most primitive prokaryotes can carry out the functions of life.
