Answer: Interphase is the phase in the cell cycle during which cells that will undergo mitosis prepare for division. In interphase, DNA of the cell copies. After that cell undergoes mitosis, which is the phase of the cell cycle during which cell divides on two identical. Mitosis consists of four phases:

1. Prophase: Chromatin in the nucleus condenses and chromosomes pair up

2. Metaphase: Chromosomes line up at the centre of the cell.

3. Anaphase: The sister chromatids separate from each other to the opposite sides of the cells.

4. Telophase and Cytokinesis: Membrane forms around each set of chromosomes on two opposite sides of the cells and cell divides into two identical daughter cells.

How does the nucleus works with the lysosomes

Inessa [10]

Answer:

Lysosome, subcellular organelle that is found in nearly all types of eukaryotic cells (cells with a clearly defined nucleus) and that is responsible for the digestion of macromolecules, old cell parts, and microorganisms.

Explanation:

Hope this helps!

The nucleus houses the cell's DNA and directs the synthesis of proteins and ribosomes. Mitochondria are responsible for ATP production; the endoplasmic reticulum modifies proteins and synthesizes lipids; and the golgi apparatus is where the sorting of lipids and proteins takes place.

Which type of carbohydrate aids in removal of waste?

charle [14.2K]

The type of carbohydrate which aids in removal of waste are dietary fibers, complex type of carbohydrate. During processing, food with complex carbs such as wheat or kernel retain its nutrients. These food types are slowly digested throughout the body. Their high nutrient content helps in digestion while preventing gut-associated discomforts, and allows smooth removal of waste as well as other toxins.

Transport proteins can become saturated with solute, have specificity for certain substances, undergo conformational (shape) cha

snow_tiger [21]

Answer:

The given characteristics can be shown by Enzymes.

Explanation:

Enzymes are substances, mostly proteins, that helps in increasing the speed or rate of a biochemical reaction (conversion of substrate to product) by reducing the activation energy barrier of the reaction.
The enzymes which are made up of proteins have an specific location or region inside them which is called the Active Site.
The biochemical reaction occurs at this active site.
The specific substrate molecule(s) comes and associated with the active site of the enzyme, mostly by means of non-covalent interactions.
By means of amino acid side chains (which have a definite pKa) the exact environment (oxidising or reducing) required for the chemical reaction to occur is maintained by the enzyme at its active site.
After associating with its substrate(s) the enzyme undergoes certain conformational changes in order to position the substrate(s) in the correct orientation such the biochemical reaction can occur.
After the products are formed, the enzyme further undergoes some conformational changes to release them.
Enzymes are similar to transport proteins because:

When the concentration of substrates is far more than that of the available enzymes molecules, then the enzymes would get saturated with substrates, like the transport proteins.
The enzymes are highly specific for their substrates like the transport proteins.
The enzymes undergo conformational changes during the biochemical reaction like the transport proteins.
Both the rate of enzymatic reaction and membrane transport is regulated by the cell.

Which of the following best describes bases?

lidiya [134]

Answer:

They turn moist red litmus paper blue and they react with metals.

They turn moist red litmus paper blue because they have a pH range of 8-14, hence they are indicated by a blue colour of the litmus.

They react with metals because they are reactive, the reaction forms a metal salt and water.
