Hope this helps for number 2 not worried about points
A chemical reaction can be described by discussing the chemical substances at all steps. It is more efficient to use a chemical equation than words, and there are agreed-upon conventions to summarize the reaction, the substances that take part in it, the products, and the amounts
Answer:
The active site of an enzyme is the region of an enzyme where substrate molecules bind and undergo a chemical reaction.
Explanation:
This is because enzymes catalyses reaction by first lowering it activation energy and then bind to the reactants and convert the substrate to products. This take place in the active site. This active site is that area or region where the activation energy is lowered and the substrate molecules is bind to produce products.
Rough endoplasmic reticulum, Golgi apparatus, cell membrane are structures that a protein that is destined to leave the cell would interact with on its journey from synthesis to exile from the cell of his birth.
The ribosomes, which are the molecules in charge of producing proteins, are what give the rough endoplasmic reticulum its name. A specific RNA fragment may instruct a ribosome to move to the rough endoplasmic reticulum and embed itself if it comes across there. The protein produced from this region will wind up inside the rough endoplasmic reticulum, where it will fold and be marked for transport to the Golgi apparatus through the process of glycosylation, which involves the addition of a tag molecule (often a carbohydrate).
Near the nucleus, the rough endoplasmic reticulum, which is continuous with the nuclear membrane, resembles a network of canals. Rough endoplasmic reticulum-produced proteins are either meant to form a membrane or to be released from the cell membrane. It would be much more difficult to discern between proteins that should exit the cell and proteins that should remain if there were no rough endoplasmic reticulum. As a result, the rough endoplasmic reticulum promotes cell specialization and increases organism complexity.

Answer:
D
Explanation:
D is the correct answer. The rest do not represent evolution / natural selection well, and penicillin's strength has remained the same.
<span>Birds
Birds are organisms which utilize a one-way air flow through their lungs to maximize air flow efficiency and oxygen consumption
The process of respiration is essential in the oxygen/carbon dioxide cycle. Respiration removes OXYGEN from the atmosphere and produces and releases CARBON DIOXIDE to the atmosphere.answer is letter D.
Respiration driven by a mechanical series called inhalation and exhalation. We inhale or breathe in oxygen and exhale or breathe out carbon dioxide.
