Why are lysosomes important?
When a cell is beyond repair, lysosomes help it to self-destruct in a process called apoptosis.
Answer: A lysosome is a membrane-bound cell organelle that contains digestive enzymes soooo. They break down excess or worn out cell parts, they may be used to destroy invading viruses and bacteria. If the cell is damaged beyond repair, lysosomes can help it to self-destruct in a process called programmed cell death, or apoptosis.

Scenario:Fossils show that many species, or kinds of organisms, have died out or become extinct because they could not respond to the pressures fast enough to survive. Those that did survive were better suited to their environment. Evidence shows that new species develop from old species as a result of gradual change. Natural selection is one process by which organisms change over time. Evidence shows that species change over time, sometimes giving rise to new species.External DataPrompt:Look at the pictures above that show how the giraffe got such a long neck.

Max is helping his parents move to a new house. He picks up one box and is able to carry it into the house. He tries to pick up a second box with an identical volume, but he is unable to lift it. What is most likely the difference between the two boxes?
Answer:
The Weight
Explanation:
Even know it has the same volume does not mean it has the same mass and weighs the same with the items inside the box. Most likely, that the Items inside the box are heavier then the first box Max moved.
Max is helping his parents move to a new house. He picks up one box and is able to carry it into the house. He tries to pick up a second box with an identical volume, but he is unable to lift it. The difference between the two boxes is weight.
What is, an identical volume ?Similar items have the identical volume. In other words, two items have the same volume if all of their measures completely match. An object's volume remains unchanged when it is rotated or reflected.
According to Avogadro's law, all gases with an identical volume and the same temperature and pressure have an equal number of molecules. If the temperature and pressure are constant, the volume and amount (in moles) of an ideal gas for a given mass are directly proportional.
The relationship between mass and volume can be easily determined using density; for example, the mass of a body is equal to its volume multiplied by the density (M = Vd), whereas the volume is equal to the mass divided by the density (V = M/d).
Thus, He tries to pick up a second box with an identical volume, but he is unable to lift it. The difference between the two boxes is weight.

destruction of habitat.
introduction of competing species.
The most common way humans contribute to the extinction of organisms is by destroying their habitats. By destroying the natural habitats of organism we are leading them to point where they cant survive.
What is extinction ?Extinction of an organism is the gradual disappearance of the entire species of that organism due to natural calamities, human activities or, spreading diseases.
Human activities are the main culprits of the devastation of organisms and their habitats. Humans destroy the natural habitats of plants and animals for their selfish purposes.
Animals then starve and they are not fit to survive in other places which are entirely different from their natural habitat. Therefore, if these activities continues they will extinct.
