How does a change in pH above or below optimal pH affect enzyme
function?
A. No change
B. Reaction happens faster
C. Enzyme dies
D. Enzyme denatures
Answer:
[tex]\boxed {\tt D. \ Enzyme \ denatures}[/tex]
Explanation:
Extreme temperatures or pH can denature enzymes.
Enzymes have a very special and specific shape that determines which substrate they can act on. If the pH changes too dramatically, then the peptide bonds holding the amino acids of the enzyme together break.
When the bonds break, the enzyme loses its shape and it cannot function anymore.
So, there is a change, the reaction doesn't happen faster or die. We can eliminate choices A, B, and C. The correct choice is D. enzyme denatures

What do you mean by biodiversity?Biodiversity or biological diversity is the variety and variability of life on Earth. Biodiversity is a measure of variation at the genetic, species, and ecosystem level.
Scientists often speak of three levels of diversity: species, genetic, and ecosystem diversity. In fact, these levels cannot be separated. Each is important, interacting with and influencing others. Changes at one level can cause changes at other levels.
Most people recognize biodiversity by species—a group of individual living organisms that can interbreed. Examples of species include blue whales, white-tailed deer, white pine trees, sunflowers, and microscopic bacteria that can't even be seen by the eye.

What statement is correct about the polarity of a water molecule?
earth can support the survival of organisms.what is/are the factory/s that make/s earth habitable?
Answer:
The factors that make Earth support the survival of organisms are it's correct distance from the sun, the Earth is protected by solar radiation by it's magnetic field, stability of it's warm atmosphere, availability of some chemical composition that support life like oxygen, water, nitrogen e.t.c., proximity of the sun in allowing the passage and flow of water, the shape and size of the Earth as Rocky planet e.t.c.
Explanation:
Earth is the planets that support the survival of living organisms and this is because of the following factors that support the existence of life and these factors includeit's correct distance from the sun, the Earth is protected by solar radiation by it's magnetic field, stability of it's warm atmosphere, availability of some chemical composition that support life like oxygen, water, nitrogen e.t.c., proximity of the sun in allowing the passage and flow of water, the shape and size of the Earth as Rocky planet e.t.c.
It's correct distance from the sun makes it's to have stable temperature i.e not to hot and not too cold. With the temperature, living organisms can survive and live.
Earth is protected from solar radiation by ozone layer and it's magnetic field. This layer hinders the penetrations of some harmful Ray's it radiations that can damage it destroy living organisms.
It's allow water flow and water is essential for life . It is useful for plants for growth , photosynthesis and germination. Water is essential for animals because, it's aids digestion and metabolic processes.
Earth's atmosphere have right composition of chemicals that support life and these chemicals include oxygen, nitrogen, carbon, water e.t.c.
For example oxygen is important for respiration which releases energy to perform cellular activities.
