- Chromosomes are made of DNA that contain genes that control the production of ______ within the cell.
Chromosomes are made of DNA and contain genes that control the production of proteins within the cell, which is in Option 2, because the DNA contains the blueprint of the cell and the living organism.
What is the significance of DNA as a blueprint?The DNA acts as a blueprint in which all of the cell's information is stored, such as in the form of a gene, which is later expressed in the cell in the form of polypeptides, proteins, enzymes, and so on by the translation process, and controls and regulates the cell for various functions. DNA contains lots of genes, but not all of them are expressible.
Hence, chromosomes are made of DNA and contain genes that control the production of proteins within the cell, which is in Option 2, because the DNA contains the blueprint of the cell and the living organism.

what happens to a enzyme after it has completed a reaction?
Answer: The enzyme will always return to its original state at the completion of the reaction. One of the important properties of enzymes is that they remain ultimately unchanged by the reactions they catalyze. After an enzyme is done catalyzing a reaction, it releases its products (substrates).
Enzymes are not consumed in the reaction, they can continue catalyzing more reactions, they can remain bound to the product or they can be degraded.
What are enzymes?Enzymes are biomolecules that catalyze chemical reactions in living organisms. They are typically proteins, although RNA molecules known as ribozymes also exist. Enzymes are responsible for many of the metabolic processes that occur in cells and are essential for life. They are highly specific, meaning that they typically only catalyze one or a few specific reactions, and they increase the rate of reactions by reducing the activation energy required for the reaction to occur.
After an enzyme has completed a reaction, it is still present and can continue to catalyze more reactions. Enzymes can catalyze thousands of reactions per second, and they can remain active for long periods of time. However, enzymes can also be inactivated or destroyed by various factors, such as high temperatures, changes in pH, or the presence of certain chemicals

Why is mass a better unit for measuring matter than weight?*
Because mass can change, but weight doesn't
Because mass is constant, while weight depends on gravity.
Because it makes more sense.
Answer:
Because mass is constant, while weight depends on gravity.
Explanation:
For example, your mass on Earth will be the same as your mass on planet Mars. Your weight however, will change depending on the force of gravity exerted on you.

What is one reason scientists are trying to culture meat in laboratories instead of simply hunting or raising animals?
Answer:
Many reasons - but a really good question.
Explanation:
Cruelty - eating meat poses ethical issues to some people. They dont eat meat because they dont believe animals should be harmed. Growing laboratory meat takes away the need for slaughter.
Land used - a big issue with producing meat is the amount of land we need to raise cattle and to grow the food to feed cattle. Rainforest, woodlands, moorland have to be destructed to make way for pasture land for cattle. The food that cattle or animal eats also needs to be grown, which requires more land. Laboratory grown meat doesnt require all the pasture space for raising or feeding animals.
Water use - the amount of water that goes into producing meat is very high when compared to amount of meat that you get back. Water availability is another global issue that may be able to be addressed by lab produced meat.
When animals are reared from meat, they may be killed in unethical ways thereby making it ethically irresponsible to raise animals for meat.
Animals are widely used as food. This food from animals or having animal origin is known as meat. The ethical issues are of key importance in raising meat for food.
