Answer:
The correct answer is option 1. Before and After Cell Division
Explanation:
Point mutations are frequently the result of mistakes made during DNA replication, although modification of DNA, such as through exposure to X-rays or to ultraviolet radiation, also can induce point mutations. But they may also occur after as well as before the division of a cell.
which mutations are beneficial? which might not make a difference? which ones are most harmful?
Answer:
Mutations are random Mutations can be beneficial, neutral, or harmful for the organism, but mutations do not “try” to supply what the organism “needs.”

Read this paragraph from "How Water Loss Affects Biodiversity."
“When a region experiences a significant drought, many animals may die from lack of water and food. […] If tourism declines due to high wildlife casualties, then the locals who depend on income from tourism will lose their livelihood. People may then turn to farming to earn money, but crops require water to grow. This can place further strain on the water supply and worsen the original problem of the drought.”
What event can cause many animals to die from lack of water and food?
Answer:
Eggs and fried chicken with mentally stabled fries
How does carbon atom work on plants
Answer: Carbon moves from the atmosphere to plants. In the atmosphere, carbon is attached to oxygen in a gas called carbon dioxide (CO2). Through the process of photosynthesis, carbon dioxide is pulled from the air to produce food made from carbon for plant growth.This energy makes carbon molecules an excellent source of fuel for all living things. During photosynthesis, plants absorb carbon dioxide and sunlight to create fuel glucose and other sugars for building plant structures. This process forms the foundation of the fast (biological) carbon cycle.

6CO2 + 6H2O → C6H12O6 + 6O2.The equation for photosynthesis is given as:
6CO₂ + 6H₂O ----> C₆H₁₂O₆ + 6O₂
PhotosynthesisPhotosynthesis is the process by which green plants manufacture their food from carbon dioxide and water in the atmosphere using sunlight as an energy source.
Carbohydrates are produced while oxygen is given off as a by-product in photosynthesis.
During photosynthesis, the energy from the sunlight is trapped by the chlorophyll found in the chloroplast and used to energize the reactions involved in photosynthesis.

what part does chlorophyll play in photosynthesis?
Answer:
Explanation:
Chlorophyll's job in a plant is to absorb light—usually sunlight. The energy absorbed from light is transferred to two kinds of energy-storing molecules. Through photosynthesis, the plant uses the stored energy to convert carbon dioxide (absorbed from the air) and water into glucose, a type of sugar

Photosynthesis has the process through which plant cells use carbon dioxide & water to create oxygen & energy rich organic compounds. They do so by converting sunlight ie light energy into chemical energy. This is possible due to presence of chlorophyll in them. Animals can't do so, as they dont have chlorophyll.

Bob has brown hair and Sally has blonde hair. If brown hair is dominant and blonde hair is recessive, is it possible for Bob and Sally to have a blonde-haired child? Use the GENOTYPE of each parent to EXPLAIN your answer.
Answer:
Yes, it is possible.
Explanation:
Bob could either be h.o.m.ozygous (BB) for brown hair or h.e.terozygous (Bb) for brown hair. If Bob is h.e.t.erozygous for brown hair, this means he has a blonde hair allele. For a child to be blonde, the child needs one blonde allele from each parent and this is possible if Bob has a blonde hair allele. However, it is not possible if Bob is h.o.m.ozygous for brown hair.
In the image, there is a punnet square showing the possible genotypes of the children if Bob is h.e.t.erozygous for brown hair.

Answer:
Active site of an enzyme must be attached to a substrate
Explanation:
Active site of an enzyme must be attached to a substrate
For an enzyme to be able to catalyse a reaction, the active site must bind with the specific substrate. This is referred as 'enzyme-substrate' complex.
Why do enzymes catalyse a reaction?Enzymes have the property of catalytic activity. All the enzymes are proteinaceous in nature. Enzymes specifically bind with the substrate and thus initiates a catalytic reaction. This is referred as enzyme-substrate specificity.
Enzymes associate with the substrate at a specific site by lowering the activation energy. This forms the active site where the reaction occurs. The substrate thus transforms into the product upon the action of enzyme.
Enzymes are unique as they speed up any chemical reaction. They help in achieving the equilibrium at a faster rate. Daily thousands of enzymatic reactions are carried out in the body.
Thus, enzymes are important in the biochemistry as they persuade chemical reactions.
