Answer: Enzymes are required for most chemical reactions in living cells because these reactions need to happen very quickly and need a catalyst. Enzymes are catalysts for chemical reactions in living things. Enzymes, being a catalyst, decreases the activation energy needed to start a chemical reaction and, as a result, also increases the rate of the chemical reaction.

Answer:
Cancer is a disease that involves uncontrolled cell division caused by a genetic mutation. It can occur in almost any region in the body. So, cancer is essentially uncontrolled mitosis of specialized cells
Explanation:
It can occur in almost any region in the body. So, cancer is essentially uncontrolled mitosis of specialized cells. The correct options are b and c respectively.
What is cancer?Cancer is a medical condition in which cells in one portion of the body expand and multiply inconsolably.
Cancerous cells have the ability to invade and destroy healthy tissue, including organs. Cancer can start in one part of the body and spread to other parts. This is referred to as metastasis.
Cancer is caused by changes in genes, which are the basic physical units of inheritance. Genes are organized in chromosomes, which are long strands of tightly packed DNA.
Cancer is a genetic disease, which means that it is caused by changes in genes that regulate how our cells function, particularly how they grow and divide mitotically.
Thus, the correct options are b and c respectively.

Chloroplasts contain chlorophyll a, chlorophyll b, and carotenoids. Why is this important in the process of photosynthesis? Support your answer with facts.
Answer:
Explanation:
Photosynthesis is the process by which green plants synthesize their food from carbon dioxide and water by using the green pigment chlorophyll generating oxygen as product.
Chlorophyll "a " absorbs light from the orange-red and violet-blue areas of the Electromagnetic spectrum. Also Chlorophyll a transfers energy to the reaction center and donates two excited electrons to the electron transport chain
Its main role is as a primary electron donor in the electron transport chain. So the energy from the sun will ultimately become chemical energy that can be used by the plant for cellular processes.
Chlorophyll "b" absorbs blue light. The main role is to expand the absorption spectrum of organisms.
Plant can absorb more energy from the high frequency blue light part of the spectrum. Its presence in cells helps plant convert a wider range of the energy from the sun into chemical energy.
Carotenoids are usually red, orange, or yellow pigments, and include the compound carotene. These compounds are composed of two small six-carbon rings that are connected by a "chain" of carbon atoms. As a result, they do not dissolve in water, and must be attached to membranes within the cell. Carotenoids cannot transfer sunlight energy directly to the photosynthetic pathway, but must pass their absorbed energy to chlorophyll. For this reason, they are called accessory pigments.
Answer:
The presence of chlorophyll a, chlorophyll b, and carotenoids in chloroplasts allow plants to absorb more energy from sunlight by absorbing multiple wavelengths. Chlorophyll a absorbs blue-violet light and red light. Chlorophyll b absorbs mostly blue light. Carotenoids absorb violet, blue, and blue-green light. The pigments together, therefore, are able to absorb a wider range of wavelengths.

A collision between which two types of crust will most likely produce a mountain range?
Answer:
Be more specific
Explanation:
Answer:
A convergent boundary
Explanation:
Convergent boundaries are pieces of crust that collide against each other. They push upwards, and that land that is pushed upwards is a mountain. Mount Everest is a good example. It was made in two tectonic plates, and since these plates are still pushing upwards to this day, this mountain grows around 40 cm each year. I hope this helps!
