Describe the core idea structure and function

Answers

Answer 1
Answer: This has the potential to be a very long answer but I will try to be brief :) Structure is intertwined with function. Often, structure is what determines or enables function and this applies to molecules, macromolecules, and all the way up to organisms. If the structure of something is changed, often the function is too. One prime example of this is in proteins. This is why when they are denatured (their shape changes) they no longer function correctly.

Which one of the following statements holds true for the induced-fit model?a. Once the enzyme binds to the specific substrate molecule, no structural changes can occur in the active site of the enzyme.
b. Once the enzyme binds to the specific substrate molecule, structural changes can occur in the active site to accomodate the product.
c. Once the enzyme binds to a specific substrate molecule, subtle structure changes occur in the active site, which are reverted when the reaction is over.

Answers

C. once the substrates bind to the enzyme, the active site of the enzyme changes, to the shape of the substrate. Once the product detaches from the enzyme, then the active site returns to it's normal shape

An object at rest will stay at rest and an object in motion will stay in motion at a constant speed and in the same direction, unless acted on by an unbalanced force.” The statement above is Newton’s first hypothesis of motion because it makes a prediction. theory of motion because it is a widely accepted explanation. law of motion because it is a factual statement based on observations. explanation of motion because it is widely accepted and based on observations.

Answers

The statement that 'an object at rest will continue to stay at rest and an object in motion will stay in motion in same direction and at constant speed unless some external force acts on the object' is a law of motion. This statement describes a fact which is base don the observations made by Newton. It is universally true and hence, it is not a hypothesis, or theory but a law.

Hence, the correct answer is 'law of motion because it is factual and based on observations'.
This would be Newton's first law of motion as it is a factual statement based on observations.

In a scientific investigation, the term “quantitative data” refers to numbers that are usually followed by

Answers

As I know the values of variables that are registered with a number that have meaningful sense, is called quantitative data. Depending on what value has the potential to take a variable, are two types of quantitative data: discrete and continuous.     

Discrete - this is such a variable that can only take values from a list of specific numbers.     

Continuous shall assume any variable that is not discrete. It takes the value of a certain period.

Answers

Behavioural genetics is the study of the effects of genes as well as well the environment on the behaviour of the individuals. The scientists who study the Behavioural genetics are known as behavioural geneticists.

In this case Dr. Hakim is studying the influence of genes and the environment on the aggression, which is a kind of behaviour. Hence, Dr. Hakim is a  behavioural geneticists, and he works in in the field of behavioural genetics.

A land developer and several ecologists are discussing how a parcel of private land should be developed while saving 20 hectares as natural habitat. The land developer suggests that the 20 hectares be divided into twenty separate 1-hectare areas. The ecologists suggest that it would be better to have one intact parcel of 20 hectares. What is the significance of these different arrangements of the 20 hectaresA. The isolated hectare piots increase the ability of individuals to disperse from one habitat to another. B. The large plot will create more inbreeding in many species C. There really is no difference: they should both work equally well. D. The isolated plots are more vulnerable to edge effects.
