Which organelle is correctly paired with its function?
A) nucleus - provides carbohydrates for fermentation
B) Chloroplast - serves ae the site for photosynthesis
C) centriole - synthesizes digestive enzymes
D) lysosome - packages cellular products
Answer:
B) Chloroplast - serves ae the site for photosynthesis
The function of chloroplast is to synthesis food.
The organelle that is correctly paired with its function is the chloroplast, which serves as the site for photosynthesis and is present in Option B as the chloroplast is the site of food synthesis.
What is the significance of chloroplasts in plants?Chloroplasts are cell organelles that are found in the cells of green plants, algae, and some other photosynthetic organisms and are the site of photosynthesis, which is the process by which plants convert light energy into chemical energy in the form of glucose, and it absorbs light energy, which is then used to convert carbon dioxide and water into glucose through a light reaction and the Calvin cycle, and the animals and plants get their food from it.
Hence, the organelle that is correctly paired with its function is the chloroplast, which serves as the site for photosynthesis and is present in Option B as the chloroplast is the site of food synthesis.

Some examples of nonpolar molecules include fats, oils, and waxes. How do these substances interact with water?
Answer: Fats and oils are nonpolar, so they will remain separate from molecules of a polar solvent such as water. Sodium and chloride ions are attracted to charged regions on molecules of polar solvents such as water.
Explanation: Nonpolar molecules do not dissolve easily in water. They are described as hydrophobic, or water fearing. When put into polar environments, such as water, nonpolar molecules stick together and form a tight membrane, preventing water from surrounding the molecule.

If there is an increase in mass, what has happened?
Answer:
The greater the mass of an object, the less it will accelerate when a given force is applied. For example, doubling the mass of an object results in only half as much acceleration for the same amount of force. Q: Tony has greater mass than the other two boys he is racing (pictured in the opening image).
Explanation:
Answer:
The greater the mass of an object the more it will accelerate! when a given force is applied the mass of the object will change and thats what causes something called speed! Now you will also increase in energy and it will be hard to slow the object down.

Answer: A(Rise)
Explanation: Air flows from high pressure, to low pressure. for example: there are 2 rooms, one is cold and is warm that of warm room is thinner air rising towards the ceiling when the air from the two rooms gets mixed. now the cold air will be leaving the room close to the floor. At the same time, warm air from the warm room will rise and move into the cold room close to the ceiling

Insulin lowers the blood-sugar levels in the body.
What are the functions of insulin?Insulin is a peptide hormone produced by beta cells of the pancreatic islets encoded in humans by the INS gene. It is considered to be the main anabolic hormone of the body.
After you eat, carbohydrates break down into glucose, a sugar that is the body's primary source of energy. Glucose then enters the bloodstream. The pancreas responds by producing insulin, which allows glucose to enter the body's cells to provide energy.
Insulin is a peptide hormone secreted by the β cells of the pancreatic islets of Langerhans and maintains normal blood glucose levels by facilitating cellular glucose uptake, regulating carbohydrate, lipid and protein metabolism.

Answer:The trophic level of an organism is the number of steps it is from the start of the chain. A food web starts at trophic level 1 with primary producers such as plants, can move to herbivores at level 2, carnivores at level 3 or higher, and typically finish with apex predators at level 4 or 5.
Explanation:
A carbon atom has 6 protons and 6 electrons. Carbon has three naturally occurring isotopes, carbon-12, carbon-13, and carbon-14. Which of these statements is true about carbon and its isotopes? A.All carbon atoms have six neutrons. B.All carbon atoms have six protons and six electrons. C.Atoms of all carbon isotopes have either more than 6 electrons or fewer than 6 electrons.
Answer:
The correct option is B
Explanation:
Isotopes of the same element have the same atomic number (number of protons) but different mass number. Hence, all the three naturally occurring carbon isotopes mentioned in the question have 6 protons each. Since the number of protons in a neutral atom is equal to the number of electrons in the same atom, each of these isotopes also have 6 electrons.
However, to determine the number of neutrons in each atom, the number of protons (atomic number) is subtracted from the mass number.
Hence, the number of neutrons in carbon-12 is 12 - 6 = 6
the number of neutrons in carbon-13 is 13 - 6 = 7
the number of neutrons in carbon-14 is 14 - 6 = 8
From the explanation above, it can be noted that the number of protons and electrons in isotopes of the same element are the same while the number of neutrons in these isotopes are different. Hence, the correct option is B

Do you think partial melting will occur if there is direct contact of hot molten rock in the Earth’s crust?
Answer:
As it moves toward the surface, and especially when it moves from the mantle into the lower crust, the hot magma interacts with the surrounding rock. This typically leads to partial melting of the surrounding rock because most such magmas are hotter than the melting temperature of crustal rock.
