Glucose is broken down in the chemical processes of aerobic respiration.

Papessa [141]

$\bold{\huge{\purple{\underline{ Answer }}}}$

Aerobic respiration :- Aerobic respiration is process of respiration in which complete oxidation of glucose takes place in the presence of oxygen

That is, 

Aerobic respiration is takes place in four stages :-

Glycolysis
The link reaction
The Krebs cycle
Oxidative phosphorylation

In aerobic respiration, Glucose with 6 carbon atoms broken into 2 pyruvic acid each with 3 carbon atom and produces water + CO2 + energy.

<h3>Whereas, </h3>

Anaerobic respiration :- is the process of respiration in which incomplete oxidation of glucose takes place in the absence of oxygen

The end products of glucose in anaerobic respiration is

In human muscles,  Lactic acid + Energy
In yeast, Ethanol + CO2 + Energy

Hence, Option D is the correct answer.

A cell that consists of a 65% salt concentration is placed in a solution with a 27% salt concentration. What will happen to this

zzz [600]

Answer:

The correct answer would be - the cell will get water and expand.

Explanation:

If a cell with a higher salt concentration is placed ins a low salt concentration solution then the water will move through the cell membrane into the cell and the cell will swell or expand.

Water always moves from a low solute concentration to a high concentration area, therefore, if the cell has more salt concentration than outside the cell water move inside the cell which leads to an increase in the water concentration inside the cell and expands its size.

Below is a picture of a tomato plant. It is a multicellular organism with many parts that work together to keep the plant alive.

galben [10]

Answer:

1. Roots: anchor the plant in soil and absorb water and minerals

2: Stem: Holds the plant upright and bear leaves, branches and fruits.

3. Leaves: Carry out photosynthesis to make food for other plant parts.

4. Flower: serves as organ of reproduction to maintain the continuity of the species.

Explanation:

1. Roots: The cells of roots are specialized to penetrate the soil deep to anchor the plant and absorb water and minerals for nutrition of plants.

2: Stem: The cells of stem impart mechanical strength to keep the plant upright and bear leaves, branches and fruits.

3. Leaves: Cells of leaves have chlorophyll pigment to carry out photosynthesis to make food for other plant parts.

4. Flower: Some of the cells of flowers produce male and female gametes that fuse leading to seed formation. Seed germination maintains the continuity of the species.
