One member of a pair or series of genes that occupies a specific position on a specific chromosome is referred to as ______.

Answers

Answer 1
Answer:

DNA is sometimes referred to as the blue print of the cell's information because it is the store house in which all genetic information necessary for the cell's survival and reproduction is kept.

Without DNA, there cannot be any continuation of life and  no new generation of organisms. All living cells and organisms are essentially made up of protein in different forms.

What is the mechanical advantage of a machine that applies a force of 1000 N to an object when a force of 500 N is applied to the machine?

Answers

The mechanical advantage of the machine in the problem is 2. By definition, the mechanical advantage of a machine is equivalent to the ratio of its output force to its input force. Since it applies a force of 1000 N to an object, that is its output. Also, since a 500 N force is applied to the machine, that is its input. So 1000/500 = 2.

Answer: 2

Explanation:

  • The mechanical advantage of a machine is defined as the amplification of the force produced when using a machine or a tool.
  • In mathematical terms, it is the ratio of the output force to input force and, the formula is :

       MA = Fo/Fi

       Where MA= mechanical advantage

       Fo= Output force

        Fi = input force.

  • According to  the question, Fo= 1000N

       Fi= 500 N

  • Therefore, MA= 1000/500 = 2

The study of animals' structures, behaviors, functions, and evolution is called _____. ethology zoology biology physiology

Answers

Answer:

The correct answer is option B, Zoology

Explanation:

Let’s look at the definition of each term one by one –

a) Ethology – Ethology deals with the study of animal behaviour and the evolutionary factor that led to the development of such behaviour in any organism.  

b) Zoology – It is the study of animals and their nature, physiology, genetic history, evolutionary pattern and behaviour.  

c) Biology – It deals with the study of all sorts of living organisms.  

d) Physiology – It deals with the physical functioning of the organism and their parts.  

It is the zoology that includes study of every thing about animals i.e anatomy, behavior, physiology, evolutionary pattern etc. Thus option B is correct.

the answer is zoology because zoology is the study of animals and thier behaviors, envrionments, and etc.

Why do you think that parasitism exists, when one of the organisms is harmed by the relationship?

Answers

Because although one organism is harmed, the other benefits. So the organism that benefits won't stop the action that is harming the other. Hope that makes sense!
