<span>Option 1: Sunlight is the energy source for plant photosynthesis.
True: In photosynthesis, plants convert light energy from the sun to chemical energy in the form of glucose.
Option 2: Chlorophyll is contained in organelles called chloroplasts.
True: Chlorophyll in the chloroplasts is what allows many wavelengths of light for be absorbed and used for photosynthesis.
Option 3: A by-product of photosynthesis is carbon dioxide.
False: Plants require carbon dioxide to create glucose, and produce oxygen as a by-product.
Option 4: Roots have tiny root hairs that maximize the plant's ability to absorb water.
True: Root hairs are very important for the absorption of nutrients and water by plant roots. </span><span /><span>

Answer:
The correct answer is b glucose is broken down into two pyruvate molecules.
Explanation:
Krebs cycle is one of the most important step of aerobic respiraion.Krebs cycle occur within mitochondrial matrix.During krebs cycle the acetyl CoA generated from pyruvate reacts with oxalo acetate in a cyclic manner to regenerate 4 carbon compound oxaloacetate.
During krebs cycle pyruvate is broken down or oxidized to form 2 carbon compound known as acetyl CoA and carbon dioxide as byproduct.
But the breakdown of glucose into two pyruvate molecules occur during glycolysis.
Answer:
Cellular division causes organisms to grow primarily by increasing "the number of cells in an organism."
Explanation:
The parent cell is also making a copy of its DNA to share equally between the two daughter cells. The mitosis division process has several steps or phases of the cell cycle—interphase, prophase, prometaphase, metaphase, anaphase, telophase, and cytokinesis—to successfully make the new diploid cells. Most of the time when people refer to “cell division,” they mean mitosis, the process of making new body cells. During mitosis, a cell duplicates all of its contents, including its chromosomes, and splits to form two identical daughter cells.
The names of the respiratory structures involved include the following: nasal cavities (or oral cavity) > pharynx > trachea > primary bronchi (right & left) > secondary bronchi > tertiary bronchi > bronchioles > alveoli.
<h3>What is respiration?</h3>
Respiration is defined as the oxygenation of blood through the intake of oxygen and the removal of carbon dioxide.
The pathway of oxygen gas molecule from the surrounding air through the respiratory system to the blood include respectively the following:
- Nasal cavities (or oral cavity): This has a direct association with the outside oxygen from the environment.
- pharynx: This so also called the throat.
- trachea: This is also called the wind pipe.
- Primary bronchi (right & left): This divides from the trachea to form two bronchi.
