Answer: The cell would swell and burst, because the 0.2% salt solution is hypotonic with respect to the cell, causing a net movement of water into the cell.
Explanation:
An animal cell with an internal salt concentration of 0.8% will shrink if it were placed in a salt solution with a concentration of 20%.
OSMOSIS:
Osmosis is the movement of water molecules from a region of higher concentration to a region of lower concentration via a semipermeable membrane. Movement of water in osmosis is based on concentration gradient i.e. difference on concentration of solute inside and outside the cell. Water will move from a cell with more water or less salt concentration i.e. the internal cell with 0.8% salt concentration to a solution with less water or more salt concentration i.e. 20% salt concentration. This will cause the cell to lose water to its external solution, and, hence, shrink.Learn more about osmosis at: https://brainly.com/question/264225?referrer=searchResults

When a pinecone is open, it disperses its seeds. Based on your experiment, can you tell what weather conditions are needed for pine trees to release their seeds? Explain your answer.
Answer:
If a pine seed finds the right micro-climate, it will eventually sprout and a pine seedling will start to grow. However, pine seeds are usually released in a dormant state, which is most often broken by cold stratification. As a result, a pine seed will not sprout until the following spring when warm weather and some spring moisture are present.

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.

1. How much force accelerate a bicycle and rider with mass 60 kg at 1.5 m/s?
Answer:
Force, F = 90 N
Explanation:
Given that,
Mass of the bicycle and rider, m = 60 kg
Acceleration of the bicycle and rider, a = 1.5 m/s²
We need to find the force acting on the bicycle and rider to accelerate. Let it is F. Its force is given by :
F = ma
F = 60 kg × 1.5 m/s²
F = 90 N
So, the force acting on the bicycle and rider is 90 N.

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.

Which of the following can occur because of the exchange of homologous chromosome parts during the process of meiosis?
Answer:
Muttation can occur during the exchange of genetic meterial from homologous chromosomes which may led to cause deseases in some cases.
Explanation:
Homologous chromosomes exchange genetic material during the process of meiosis.
What is Meiosis?Meiosis is a type of cell division in which germ cells present in the sexually-reproducing organisms produces the gametes, such as sperm or egg cells. It involves two rounds of division which results in four cells with only one copy of each chromosome.
These four cells are haploid in nature. Meiosis produces the sex cells or gametes like eggs in females and sperm in males.
Meiosis is divided into nine stages. These are divided between the first time the cell divides (meiosis I) and the second time it divides (meiosis II).
Thus, homologous chromosomes exchange genetic material during the process of meiosis.

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.
