Answer:

1) The correct answer is option C.

2) the correct answer is option C.

Explanation:

1) Molecular formula of glucose = C_6H_{12}O_6

Number of carbon atoms in single molecule = 6

Number of carbon atoms in 3  molecule of glucose :

\frac{6}{1}\times 3=18 atoms of carbon

There are 18 carbon atoms in the 3 molecules of glucose.

2) Homogeneous mixture is the mixture in which components are evenly distributed throughout the mixture. The shape and size of the particles are identical in the mixture.

Heterogeneous mixture is the mixtures in which component are unevenly distributed throughout the mixture. The shape and size of the particles are not identical in the mixture.

Air is the mixture of gases with 78% of nitrogen gas, 21% of oxygen gas and remaining 1 % are other gases. Air is a homogeneous mixture of different gases.

Where as water, oxygen , alcohol are pure substances.

fredd [130]

Answer:

Tamoxifen is an irreversible, competitive inhibitor.

Explanation:

In order to binds to the active site of the estrogen receptor protein, tamoxifen have to compete with the other chemical compound, and inhibits the estrogen release, so it is a competitive inhibitor. Then, you said that when tamoxifen binds to the receptor,  the protein is permanently deactivated, so it is also irreversible.

The regular sequence of growth and division that cells undergo is called the?
KIM [24]

Answer:

Cell cycle.

Explanation:

A cell can be defined as the fundamental or basic functional, structural and smallest unit of life for all living organisms. Some living organisms are unicellular while others are multicellular in nature.

A unicellular organism refers to a living organism that possess a single-cell while a multicellular organism has many (multiple) cells.

Generally, cells have the ability to independently replicate themselves. These cells can be compared to the kind of structures found in a business or factory, where you have different workers performing different functions.

In a cell, the "workers" that perform various functions or tasks for the survival of the living organism are referred to as organelles and they include nucleus, cytoplasm, cell membrane, golgi apparatus, mitochondria, lysosomes, ribosomes, chromosomes, endoplasmic reticulum, vesicles, etc.

The regular sequence of growth and division that cells undergo is called the cell cycle. This cycle makes it possible for the cells found in living organisms to divide and produce new cells.

Basically, there are four (4) phases of the cell cycle and these are;

I. Prophase.

II. Metaphase.

III. Anaphase.

IV. Telophase.

Which salt is produced when NH4OH Reacts with HNO3
borishaifa [10]

Explanation:

When an acid reacts with a base then it results in the formation of salt and water.

HNO_{3} is an acid and NH_{4}OH is a base thus, when we dissolve ammonium hydroxide in nitric acid then it results in the formation of ammonium nitrate and water.

The reaction is as follows.

 NH_{4}OH + HNO_{3} \rightarrow NH_{4}NO_{3} + H_{2}O

Hence, there will be formation of ammonium nitrate (NH_{4}NO_{3}) salt.
