Lavoisier's conclusions were considered a law instead of a theory, because Lavoisier provided sufficient empirical evidence to support his claim
What is Lavoisier law ?In his tests, Lavoisier tried to show that his theory according to which matter is never generated nor destroyed in chemical reactions was true.
The knowledge of finance, biology, chemistry, and economics that Antoine Lavoisier possessed was well known. He recognised oxygen and articulated the law of conservation of mass in 1778. He detected hydrogen, developed the metric system, and changed element nomenclature in 1783.He rightly inferred that water wasn't an element but rather a combination of oxygen and combustible air, or hydrogen as it is today known. Lavoisier used the breakdown of water into oxygen and combustible air to prove his point.Learn more about Lavoisier law here:

Why is it important that the inside of a lysosome have a lower pH than the surrounding cytoplasm in the cell? (2 points)
Lysosomes carry a variety of acid hydrolases that are active at the acidic pH kept within the lysosome, but not at the neutral pH of the cytosol.
How is the pH inside a lysosome different from that of the cytosol?Most of these enzymes are perfectly active only in the acidic lumen of lysosomes. Lysosomal pH is kept at 4.5–5 while cytosolic pH is 7–7.5. This pH difference indicates that proton absorption in lysosomes is almost 1000 times higher than in the cytosol. Lysosomes are hydrolytic enzymes. They need an acidic environment for proper work, they are mention to as acid hydrolases. These enzymes help in the disintegration of polysaccharides, proteins, lipids, nucleic acids, etc. These enzymes vital low pH compared to the cytoplasm to stay active.
So we can conclude that Lysosomes have an acidic interior pH of ~4.8 in contrast to the slightly basic cytosol (pH 7.2).

Hemoglobin is a protein that carries oxygen in red blood cells. The hemoglobin molecules produced by some people have one specific amino acid that is different from the amino acid at that position in normal hemoglobin.
Which of the following is the most likely cause of this amino acid variation?
Group of answer choices
The hemoglobin gene contains a mutation.
Enzymes replace the amino acid once the hemoglobin is produced.
An additional amino acid is mistakenly inserted into the hemoglobin during translation.
An error occurs during the folding of the hemoglobin protein.
Answer:
My best guess is "The hemoglobin gene contains a mutation".
Explanation:
Sorry, I'm not an expert so bear with me!
One more common hemoglobin-related mutation is sickle-cell anemia. It occurs when the amino acid in hemoglobin is substituted from glutamate to valine. It is considered a mutation and is a direct swap from one specific amino acid (glutamate) to a different amino acid (valine) in the same position in the hemoglobin. So, considering that our example (sickle-cell anemia) fits the criteria of swapping one amino acid for another in the hemoglobin, is a mutation, and is passed down genetically (meaning that the hemoglobin gene would need to carry the mutation) it does look a bit like it fits your parameters!
Thus, as I understand it the hemoglobin gene carrying a mutation would make sense as the most likely cause of the amino acid variation.
Again, this is based on 10 minutes of googling. I hope this helps, but apologies if I'm incorrect!! Good luck :)

The unofficial titles of some eras such as Age of Fishes, Age of Reptiles and Age of Mammals are really informative and they are not oversimplifications because these periods reflect the emergence of different taxonomic groups in the course of evolution.
What are animal eras?The animal eras are periods during the geological time in which certain groups of animals appeared in the course of evolution, which results informative to determine how evolution (change) occurred due to natural selection.
For example, mammals emerged as a taxonomic group during the Cenozoic Era, which occurred approximately 65 million years ago and this period is known as the Age of mammals.

What do you mean by heredity?
Heredity is the passing of genetic characteristics from parents to offspring. It is the process by which certain traits are passed down through generations. It is the genetic material that is passed from one generation to the next.
A larger sample size helps to reduce the amount of variability in the results due to random chance, and increases the likelihood that any observed results are actually representative of the whole population. This is especially important when studying the inheritance of traits, as the probability of a trait being passed on is often very small. By studying a large sample size, Mendel was able to accurately determine the patterns of inheritance for the traits he was studying, and gain a better understanding of the mechanisms of heredity.
Hence, option D is correct.
