Buffers resist change in ph of solutions by_____?

Answers

Answer 1

Answer: A buffer is able to resist pH change because the two components (conjugate acid and conjugate base) are both present in appreciable amounts at equilibrium and are able to neutralize small amounts of other acids and bases (in the form of H 3O + and OH -) when the are added to the solution.Feb 7, 2016

Imagine you are in a laboratory. You are exploring the following reaction: A + B → C When the product C is created, bubbles form. When 10mL of A is added to 10mL of B, the reaction takes twenty seconds. Your teacher gives you three unknown substances (X, Y, and Z), one of which is a catalyst for the reaction. Design an experiment to test substances X, Y, and Z to determine which one is a catalyst for the reaction.
Why do people die?????
Jordan is a 14 year old middle school student, weighing 275 pounds and is 5’6” tall. Over the past 2 years, he has gained 60 pounds, as he has begun to withdraw from social activities, and avoid other students, due to bullying from others his age about his weight/appearance. Lately, Jordan has been missing a great deal of school too, particularly on the days he has gym. Jordan’s parents are both average in height and weight, and Jordan’s mother says that he just takes after his grandfather William, who “was a husky man, and died of a sudden heart attack at the age of 44”. She says “We just have fat genes in the family; you can’t do anything about that”! He has been told he had “no willpower, or is weak, or that he needed to change his lifestyle, eat less and exercise more.” Jordan says “I go for a couple days without eating, but then I get so hungry that I could eat the couch”! You are the school nurse doing height and weight assessments on the middle school group this year. How would you assess and advise Jordan?

What happens to animals that are deprived of oxygen

Answers

Like humans, if an animal that needs oxygen to survive (almost every living organism) doesn't absorb enough oxygen from its environment, the organism will start to die because their cells need oxygen in order to survive. Animals use oxygen for respiration (breathing), so without it, they will not be able to supply their blood with the oxygen in order to function.

What will happen to the animal is they will soffocate and die of lack of no oxygen traveling through bones.

Did any species pairs in part B show more than one barrier to reproduction? List examples, and describe the barriers they display

Answers

Final answer:

Yes, species pairs show more than one barrier to reproduction. Examples include damselflies with incompatible reproductive organs, species of flowers attracting different pollinators, bird species with different mating dances, and species producing infertile offspring.

Explanation:

Yes, there are several instances where species pairs show more than one barrier to reproduction. These barriers can be prezygotic or postzygotic. Examples include damselfly males and females of different species that have differently shaped reproductive organs, thus creating a mechanical barrier. This means their body parts simply do not fit together and reproduction cannot occur.

Also, two species of flowers may attract different pollinators, creating a barrier known as habitat isolation, in which the species live in the same area but different habitats. Furthermore, bird species may display different mating dances. This is behavioral isolation where species differ in their mating rituals. There's also reduced hybrid fertility where two species of insects produce infertile offspring. The mechanisms of reproductive barriers in nature are complex and diverse in their operation.
