Answer ;
Phagocytosis is when smaller organisms or other food particles are eaten.
Autophagy is when a damaged organelle or small amount of cytosol becomes surrounded by a double membrane and a lysosome fuses with the outer membrane of the vesicle.
Enzymes break down the material. Food vacuoles fuse with a lysosome, whose enzymes digest the food.
Explanation;
-The Lysosomes are organelles that are responsible for intracellular digestion. Lysosomes are vesicles that contain hydrolytic digestive enzymes capable of breaking down large molecules into smaller ones.
-There are several ways in which different varieties of macromolecules may be digested by lysosomes. One mechanism is phagocytosis, the other is autophagy, which entails the removal of membrane-bounded organelles or other cytoplasmic components through the action of lysosomes, and lastly the hydrolytic enzymes may break down or digest the unwanted materials.
Answer:
a. Five-Carbon Sugar and Phosphate
Explanation:
A nucleotide can be defined as an organic molecule which forms the building block of nucleic acid such as deoxyribonucleic acid (DNA) and ribonucleic acid (RNA).
Basically, nucleotide comprises of the following parts;
1. Nitrogenous base: this includes adenine (A), thymine (T), guanine (G), and cytosine (C) which are mainly found in the DNA while adenine (A), guanine (G), uracil (U) and cytosine (C) are found in the RNA.
2. A phosphate group.
3. A penrose sugar: it is either deoxyribose in DNA or ribose in RNA.
The two parts or chemical components of a nucleotide which do not change throughout the structure of DNA are;
I. Five-Carbon Sugar also known as deoxyribose and it has hydrogen on its second carbon.
II. Phosphate: this is the structural backbone that provides support to DNA.
The process of water moving through the soil is called percolation or ground water recharge. In this process water oozes, seeps, or filter through the soil beneath the surface, without a defined channels, or in a course that is unknown and not discoverable from surface indications without excavation for that purpose. Percolation and infiltration are two related but different processes describing the movement of water through the soil. Infiltration involves the downward entry of water into the soil or rock surface while percolation is the flow of water through soil and porous or fractured rock.<span />

A silent mutation. This is when the new codon will work just as well as the old one without changing the amino acid shape.
