which body part transports oxygen,removes waste materials,and carries nutrients to the body as part of the circulatory system?

Answers

Blood

Blood is the transport fluid circulating in the body and is responsible for the transport of substances from one point to another. Blood is composed of red blood cells, white blood cells, platelets and plasma. All of these components work together and transport substances such as oxygen, glucose and amino acids to the cells and remove waste substances such as carbon dioxide and urea away from the cells. 

In a relay race, the probability that team Sapphire wins is 22%. In another unrelated relay race, the probability that team Emerald wins is 47%. How many percent probability both teams lose their races?

Answers

P(sapphire wins) = .22
P(sapphire loses) = 1-.22 = .78
 
P( emerald wins) = .47
P( emerald loses) = 1- .47 = .53
 P ( sapphire loses & emerald loses ) = P( sapphire loses) * P(emerald loses) = 0.78*0.53 = 0.4134

The number of hydrogen atoms in 6NH3 is

Answers

Answer: 18

Explanation:

This molecule, called ammonia, is a group of atoms held together by chemical bonds. In this example, the atoms (smallest pieces of matter) are nitrogen (N) and hydrgoen (H)

The number 6 indicates the number of moles of the NH3 molecule. A mole  is the unit of measurement used to measure the number of atoms or molecules. One mole is equal to 6.02214078×10^23 of the same things.

And since there are 3 Hydrogen atoms found in each mole of ammonia,  and there are 6 moles of amminia, then 6 x 3 = 18 atoms of hydrogen.

No 6 is common for N and H. 3 is only for H(Hydrogen).

For finding the number of hydrogen atoms we should multiply 6 with 3

 So, 6*3 = 18. So there will be 18 hydrogen atoms in 6NH₃

Which theory suggests that cells are the basic building blocks of life but don't constitute life itself?Cell theory or organismal theory?

Answers

Answer:

The correct answer would be the organismal theory.

The three main principles of the cell theory are:

  • All the living organisms are formed by one or more types of cells.
  • Cell forms the basic structural and functional unit of all living organisms.
  • Cell arises from the pre-existing cell.

The organismal theory was developed as a counter argument towards the cell theory.

One of the principles of this theory states that "cells are the basic building blocks of life but don't constitute life itself". For example, cells removed from a multicellular organism require specific life support systems in order to keep them alive.
This is the organismal theory: the theory that the basic unit of life is the organism, but which can be divided into cells.

Cell theory says that the basic unit of life is the cell.
