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.

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.

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.

Every winter, Alice notices that the monarch butterflies seem to disappear from her backyard garden. Then, the butterflies return to her garden each spring. Which best describes the butterflies' behavior? migration, which is a response to an external stimulus migration, which is a response to an internal stimulus flight, which is a response to an external stimulus flight, which is a response to an internal stimulus
Answer:
migration, which is a response to an external stimulus
Explanation:
The butterflies were migrating in response to external stimuli.
Migration is the movement of organisms from one place to another in response to external stimuli. The stimuli could be for food, shelter, weather, etc.
Flight in response to external stimuli is often due to the presence of danger as stimuli. The adrenal gland releases epinephrine which triggers physiological changes in the body and makes the organism decide whether to run, stay, or fight.
In this case, the butterfly could have been migrating in response to the availability of flower nectars or pollen which serve as food for them. Once flowers are available during the spring, the butterflies come around and when the winter comes and the flowers disappear, they migrate away.
Answer:
A
Explanation:
migration, which is a response to an external stimulus
Which of the following statements accurately describe variation in human skin color?

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.

What paired abiotic factors below are the most important in determining the type of
vegetation that is present in a natural ecosystem?
Answer:
D. Water and temperature
Explanation:
Abiotic factors refers to the nonliving components of an ecosystem. They include rainfall, temperature, wind, slope, soil etc. However, these abiotic factors are more important than one another in the sense that the amount of some can be used to determine the type of vegetation in a natural ecosystem.
WATER (RAINFALL) AND TEMPERATURE are two of these abiotic factors that are used as a basis in determining the type of vegetation that is present in a natural ecosystem. For example, a rainforest is characterized by high rainfall and high temperature, while a desert is characterized by low rainfall and high temperature etc

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.

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.
