List the 3 reasons why mitosis occurs
Mitosis is a cell division method a part of the cell cycle that is essential for growth and development, repair and replacement, and asexual reproduction.
What is mitosis?Mitosis is a type of cell division method that occurs in all the somatic cells and plays a crucial role in living organisms. They produce daughter cells to increase the cell number and to aid in the growth and development.
They replace and repair the damaged cells in the body and also is a form of asexual reproduction where the parent cell is divided to form a new daughter cell with the same ploidy.
Therefore, mitosis is essential for growth, repair, and asexual reproduction.

Which statement about the structure of organic molecules is true
1. DNA contains fatty acid chain
2. Lipids are composed of Amino acids
3. Proteins are composed of nucleotides
4. Carbohydrates contain monosaccharide units
Answer: The answer is D
Explanation:
The statement which is true about the structure of organic molecules is as follows:
Carbohydrates contain monosaccharide units.Thus, the correct option for this question is D.
What do you mean by Organic molecules?Organic molecules may be defined as those molecules that are correspondingly made of carbon and hydrogen. It can also include other elements like oxygen, sulfur, nitrogen, etc. It must contain carbon atoms covalently bonded to hydrogen atoms (C-H bonds).
DNA possesses monomeric units known as nucleotides. Lipids are the derivatives of fatty acids. While proteins are composed of building blocks that are known as amino acids.
On the other hand, carbohydrates are derived from monosaccharide units that are togetherly held by glycosidic linkage.
Therefore, carbohydrates contain monosaccharide units is a statement that is true about the structure of organic molecules. Thus, the correct option for this question is D.

Abrianna placed a ball of clay on a table. She flattened it into the shape of a disc. She turned to Hanna and said, "Look, I have changed the weight of the clay!" Hanna responds, "No, the weight has not
changed. The mass has." How would you respond? Write your response in your
Science Journal.
Answer:
Explanation:
Both would be right if some of the clay was removed.
Since there is no mention of anything being removed, both are incorrect. There is always the same mass when the shape has been altered.

Which of the compounds would the plant require as outputs for photosynthesis? Click on all options below that are considered outputs/products (things the plant exports during photosynthesis). (Choose up to three. Choosing all options will result in an incorrect answer)
Oxygen
Carbon Dioxide
Water
Glucose
Sunlight
In one sentence explain why carbon dioxide is considered the most important greenhouse gas, although it traps much less heat than other greenhouse gases such as methane, nitrous oxide and CFCs.
Answer:
Because plants need carbon dioxide more than any other compound/element. Also, heat doesn't make much of a difference in a plants growth or production. It's sunlight that makes a difference.
Carbon dioxide is considered as the most important greenhouse gas due to its abundancy in the atmosphere.
• In the atmosphere, climate change is mainly an issue due to high concentration of carbon dioxide in the atmosphere.
• This overload is because of the burning of fossil fuels and burning of forests.
• Apart from carbon dioxide there are many heat trapping gases like water vapor and methane, however, carbon dioxide is putting us at greater threat due to irreversible modifications it takes place if it continues to gather at such rate in the atmosphere.
• Carbon dioxide has contributed more to climate change than any other greenhouse gases between 1750 and 2011.
• The other gases like methane possess more potent heat trapping tendency per molecule in comparison to carbon dioxide, however, they are far less in comparison to carbon dioxide in the atmosphere.
• The tendency of carbon dioxide to remain in the atmosphere for longer durations in comparison to other heat trapping gases makes it the most potent greenhouse gas.
Thus, the abundancy of carbon dioxide in the atmosphere makes it the most powerful greenhouse gas in comparison to other greenhouse gases.

What do codons in DNA code for?
Answer:
mRNA and then amino acids
Explanation:
Codons are triplets (3) bases that code for defined amino acid sequences.
DNA is transcribed into mRNA. The mRNA codons are then translated into amino acid chains that form proteins.
Each codon codes for an amino acid, which is brought to the growing polypeptide chain by tRNAs via complementary base pairing.
If your body is capable of making only certain amino acids, how do we get the essential amino acids we need?
Answer:
Essential amino acids cannot be made by the body. As a result, they must come from food. The 9 essential amino acids are: histidine, isoleucine, leucine, lysine, methionine, phenylalanine, threonine, tryptophan, and valine.
Explanation:
Essential amino acids are available to the body through diet.
What are amino acids?Amino acids are the key units in protein formation. They are the building blocks in determining protein structure.
Amino acids are amphoteric molecules which means that they contain dual functional group - amino and carboxylic acid.
There are twenty different amino acids present. Amino acids are classified into four main groups:
Non polar amino acidsPolar but charged amino acidsNegatively charged amino acidsPositively charged amino acidsAmino acids are crucial in the determination of genetic code. They are also important in transcription and translation process.
Amino acids are joined together in large number and form polypetides through peptide bond formation.
Based on the nutritional requirements amino acids are classified into two types:
Essential amino acids - amino acids which cannot be synthesized by the body and thus need supplementation through diet.Non essential amino acids - amino acids which can be synthesized by the body.Therefore, amino acids are important in the biochemistry of proteins and several biochemical processes.

How are some protists like plants
Answer:
Plant-like protists are autotrophs. This means that they produce their own food. They perform photosynthesis to produce sugar by using carbon dioxide and water, and the energy from sunlight, just like plants. ... Protists can be unicellular (single-celled) or multicellular (many-celled).

What characteristics does a cell membrane have that the plastic bag does not have?
Answer:
The characteristic that differentiates the cell membrane from a plastic bag is that the membrane is permeable to the passage of substances.
Explanation:
Cell membrane covers the cell and is predominantly formed by a double layer of lipids, which gives it the main characteristic of behaving as a semi-permeable membrane. This indicates that the membrane allows the entry of some substances and prevents the entry of others.
Unlike the cell membrane, a plastic bag is impermeable, preventing the passage of water or any other substance.
