the four molecules of life are proteins, carbohydrates, lipids and nucleic acids. Each of the four groups is vital for every single organism on Earth. Without any of these four molecules, a cell and organism would not be able to live. All of the four molecules of life are important either structurally or functionally for cells and, in most cases, they are important in both ways.
this is what i have about this
Answer:
Explanation:
The main fuction of lysosomal enzymes like lipases ,proteases, carbohydrases is to hydrolyse/digest various unwanted material in the cell. And sometimes to digest some nutrient in the cell.
These enzymes are capable of digesting carbohydrates,proteins,lipids and nucleic acids. Lysosomal enzymes are produced by a memberane bound cell organel called lysosome.
WHAT IF LYSOSOMAL ENZYMES ARE ABSENT:
==＞ If lysosomal enzymes are absent then build up of various unwanted substances increase to a abnormal level, which may increase toxicity in the cell.
==＞build up of various dead or unwated cells in the body will increase,since lysosome have the capacity to digest its own cell.
==＞ absence of lysosome will will cause the cells to starve,since most of the nutrients in the cells are digested by lysosome enzyme.
==＞ Can cause a high risk of disease,since lysosome digest its own cell if it is infected with some microbial activity.

What animals did the grant study in galapagos island?
Galapagos finches did the grant study in Galapagos island.
Galapagos finches is a piece of evidence supporting the theory of evolution.
Darwin's finches comprise a group of 15 species endemic to the Galápagos (14 species) and Cocos (1 species) Islands in the Pacific Ocean. The group is monophyletic and originated from an ancestral species that reached the Galápagos Archipelago from Central or South America.
What did he observe?
During the survey voyage of HMS Beagle, Darwin was unaware of the significance of the birds of the Galapagos. He had learned how to preserve bird specimen while at the University of Edinbugh and and had been keen on shooting, but he had no expert in ornithology and by this stage of the voyage concentrated mainly on geology. Nonetheless, these birds were to play an important part in the inception of Darwin’s theory of evolution by natural selection.
What was the brief goal of their studies?
All of Darwin's observations and insights, plus reading of increasing population growth and demand for limited resources, brought him to his theory of natural selection. Briefly, this means that individuals better adapted to their environment survive and increase in number through reproduction.
What did they conclude?
Conclusion:
Charles Darwin deserves primary credit for the theory of evolution. He developed existing ideas about descent with modification while providing a large body of evidence in support of them, and he was the first person to perceive thatnatural selection is the primary force behind evolution.
The answer is F.
The lower the sediment and dirt is, the older the fossil.
The minimum pH is 4 whereas the maximum pH is 14. The optimum pH of enzyme Y is about 9.
The minimum pH is 4 whereas the maximum pH is 14. Within this range, Enzyme Y will work.
As shown in the graph, as the pH increases so does the rate of Enzyme action. The optimum pH of enzyme Y is about 9. The rate of enzyme action increase till a pH of 9, then it begins to decrease.
