Describe the function of each organelle.
Elis [28]

Answer:

Cytoplasm: Fluid between the cell membrane and the nucleus. helps protect organelles

Nucleus: A part of the cell containing hereditary information and is responsible for growth and reproduction; the "command center" of the cell.

Ribosome: A small particle in the cell that can make proteins.

Endoplasmic Reticulum: A cell structure that forms a maze of passageways in which proteins and other materials are carried from one part of the cell to another.

Golgi Apparatus: A cell structure that helps make and package materials to be transported out of the cell or for storage inside the cell.

Lysosome: Cell organelle filled with enzymes needed to break down certain materials in the cell, such as large food particles or old parts of the cell. May be found only in animal cells.

Vacuole: Saclike storage structure in the cell. can store water, nutrients, and even toxic substances.

Mitochondrion: An organelle containing enzymes responsible for producing energy. (Metabolism/respiration)

Chloroplast: An organelle found in the cells of plants and some other organisms that captures the energy from sunlight and converts it into chemical energy (photosynthesis).

Cell membrane: The thin, flexible barrier around a cell; controls what enters and leaves the cell.

Cell wall: The structure outside of the cell membrane that is used to provide support and protection. Present in plants, algae, fungi, and many prokaryotes.

A circular molecule of DNA contains 1 million base pairs. If the DNA synthesis at a replication fork occurs at a rate of 100,000
lakkis [162]

Answer:

<h2>5 minutes </h2>

Explanation:

1. In bidirectional replication;  there are two replication forks, and each proceeding at a rate of 100,000 (as given in the question) nucleotides per minute.  

2. So, by  the given rate of replication, we can calculate that, it would require 5 minutes for the circular DNA molecule to be replicated by bidirectional replication because each fork synthesize  500,000 nucleotides in 5 minutes ( 100,000 per minute) ( as given, in 5 minutes × 100,000 nucleotides per minute= 500,000 and by 2 forks= 1,000,000) within the time period.

Cellular respiration involves two phases. The anaerobic phase does not involve oxygen, while the aerobic phase does. Where does
Alex

While the majority of anaerobic (without oxygen) and aerobic (with oxygen) respiration occurs in the cytoplasm and mitochondria, respectively, of the cell.

<h3>What is cellular respiration?</h3>

The process through which food, in the form of sugar (glucose), is converted into energy within cells is known as cellular respiration. All kinds of cellular operations are then powered by the energy that is stored in ATP molecules.

There are three types of cellular respiration

1) Anaerobic respiration happens when there is no oxygen present.

2) Aerobic respiration occurs when there is oxygen present.
