Question 11

Element

Answer 11

A pure substance that cannot be broken down into other substances by chemical or physical means.

Question 12

Compounds

Answer 12

A substance made of two or more elements chemically combined in a specific ratio, or proportion.

Question 13

4 organic compounds found in cells.

Answer 13

1. Carbohydrates
2. Proteins
3. Lipids
4. Enzymes

Question 14

Organic Compounds

Answer 14

Organic compounds are the compounds which contain Carbon. Such as- Carbohydrate, Proteins, Lipids and Fat.

Question 15

Inorganic compounds

Answer 15

Inorganic Compounds are the compounds which do not contain Carbon. Such as- Water, Table Salt.

Question 16

The most necessary inorganic compounds that cells need.

Answer 16

The most essential inorganic compounds cells need to survive is- Water.

Question 17

Water in Cells.

Answer 17

Most of the actions taken in the cells need substances which are garden teed to be dissolved in water.

Question 18

Plant Cells

Answer 18

Plant cells are made of-
Golgi Apparatus
Nucleus
Endoplasmic Reticulum
Mitochondria
Vacuole
Chromosomes
Cell Wall
Cell Membrane
Chloroplast

Question 19

Animal Cell

Answer 19

An animal cell is made of-
Golgi Apparatus
Nucleus
Endoplasmic Reticulum
Mitochondria
Vacuole
Chromosomes
Lysosomes
Cell Membrane

Question 20

Cell Wall

Answer 20

The cell wall in plant cells provide the strength and thickness of the organisms stem or the outer layer. This protects the insides from damaging. Therefore, trees have a thick and hard trunk.

Question 21

Ribosomes

Answer 21

Ribosome can be found in both, animal and plant cells. It holds the RNA in place so, the amino acids canto dulce proteins.

Question 22

Nucleus

Answer 22

The nucleus in the animal and plant cells works as the brain of the cell. The nucleus contains the DNA which is contained with special codes or language for the cell to proceed certain actions.

Question 23

Mitochondria

Answer 23

The mitochondria in both, plant and animal cells does the work of breaking protein carbohydrate, lipids, enzymes and other organic material to produce energy for the cell to use.

Question 24

Organelles work

Answer 24

The organelles in the cell help the cell react and perform specific and difficult jobs to survive in an organism.

Question 25

The characteristics of living things is:-

Answer 25

Grow
Develop
Reproduce
Metabolism
Responds to Stimuli
Contains one or more cells.

Question 26

The four needs for an organism to survive are:-

Answer 26

Shelter
Food
Water
Metabolism

Question 27

Autotrophs

Answer 27

Autotrophs are organisms that can produce their own food.

Question 28

Heterotrophs

Answer 28

Heterotrophs can not make their own good. Therefore, they are consumers and feed of other organism for survival.

Question 29

Sexual Reproduction

Answer 29

A way of reproducing sexually or with two parents of two different genders.

Question 30

Asexual Reproduction

Answer 30

A way of reproducing with one parent and with very exact genes.

Question 31

Unicellular Organism

Answer 31

An organism with only one cell.

Question 32

The structure of DNA and RNA

Answer 32

A DNA is a double helix.

A RNA is a single helix.

Question 33

DNA and RNA

Answer 33

DNA consists of the instruction manual for all actions in the cell.
With the help of DNA, RNA is transferred out of the nucleus to produce proteins.

Question 34

Nitrogen Bases Pair:-

Answer 34

DNA:-
Adenine->Thymine
Cytosine->Guanine

RNA:-
Adenine->Uracil
Cytosine->Guanine

Question 35

Gene

Answer 35

A gene is approximately between 100-1,000 nitrogen bases paired up, which is the recipe for a single specific protein.

Question 36

The DNA replication

Answer 36

In DNA replication:-

1. The DNA molecule unwinds and separate, like a zipper unzipping, between the nitrogen bases.
2. Nitrogen bases in the nucleus pair up with the bases on each half of the DNA.
3. The cell develops and becomes and individual cell, apart so the body.

Question 37

Genetic Information

Answer 37

Cell->Nucleus->chromosome->gene->DNA
The genetic information is stored in the DNA. Therefore, a gene is the part which provides you yo look like your mother or father.
