Answer:

Diffusion is the movement of molecules from an area of higher concentration to area of lower concentration.

Explanation: Diffusion is a type of passive transport in which molecules moves from a region of higher concentration to the region of lower concentration. In passive transport, molecules moves from one place to another place without the use of energy.

For example, if a person spray perfume in one corner of the room after sometime the scent of perfume will be smelled in other corner due to diffusion.

Answer: Diffusion

Explanation:

Diffusion is the process or a spontaneous movement of particles from an area of higher concentration to an area of lower concentration.

Examples are;

1. perfume

2. A drop of ink in a cup of water.

From these two examples when it is dropped, especially ink, it diffused inside the entire space of the cup and fill all the space by penetrating the entire molecule of the water available.

Which variable should be changed in an experiment to test the best conditions for bacteria to grow? the type of bacteria used th
Setler [38]

An experiment to test the best conditions for bacteria to grow is the material that the bacteria feed upon. <u>Option D.</u>

<u />

Antibacterial hand soap with different concentrations. Dependent variable bacterial growth as measured by the diameter of the zone of inhibition. Exposing Petri dishes to different temperatures can skew the level of bacterial growth they inhabit. Plant height is the dependent variable that responds to changes in the independent variable.

Sunlight is the controlling variable because each plant is exposed to the same amount of sunlight. It is the dependent variable because it measures the amount of plant growth. The dependent variable depends on the independent variable. How much plants grow depends on how much sun they receive. A continuous increase in temperature from a minimum value increases the rate of bacterial growth because the rate of metabolic reactions increases with increasing temperature.

The reduced coenzymes generated by the citric acid cycle donate electrons in a series of reactions called the electron transport
Julli [10]

The reduced coenzymes generated by the citric acid cycle donate electrons in a series of reactions called the electron transport chain. The answers are as;

a) 1. NADH and 7. FADH2

b) 6. O2

c) 3. NAD+, 1. H2O, 4. ATP and 8. FAD

Oxygen is the ultimate electron acceptor, and it combines with hydrogen ions to produce H2O. This process occurs at the conclusion of the electron transport process.

ATP molecules, which are carriers of energy, would be the final outcome of the oxidative phosphorylation process.

(a) NADH and FADH2 donate electrons to the electron transport chain.

(b) O2 is the final electron acceptor.

(c)  NAD+,  H2O,  ATP, and  FAD are the final products of the electron transport chain and oxidative phosphorylation.

You can also learn about oxidative phosphorylation from the following question:

What is osmolarity? Hemopoiesis?
Andrej [43]

Answer:

Osmolarity:

Osmolarity may be defined as the number of solutes dissolved in per solution of liters. The osmolarity plays an important role in the human body as it maintains the water electrolyte balance in the body. The osmolarity of the human plasma is about 275-299 milli-osmoles/kilogram.

Hemopoiesis:

Hemopoiesis may be defined as the process of formation of blood cells in the body. The main types of blood cells formed during this process are red blood cells, white blood cells and platelets. The hemopoiesis majorly occurs in the bone marrow cells.
