The term " basic unit of matter" refers to an atom.

The atom consists of a dense central nucleus surrounded by a cloud of negatively charged electrons. The atomic nucleus  contains a mix of positively charged protons and electrically neutral neutrons  except in the case of hydrogen which is considered the only stable nuclide with no neutrons.

The electrons of an atom are bound to the nucleus by electromagnetic force. Two or more atoms can be bound to each to form a molecule.

Answer:

The correct answer will be option-Yes--every species represents a resource that may be exploited by an array of parasites

Explanation:

Parasites are the organism which for survival depends on the resources of the host organism and utilize them to the extent that it could lead to the death of the host.

The interaction between the parasite and host proves harmful to the host but beneficial to the parasite.

A number of parasites exist for human species which can directly harm humans. Similarly, a large number of hosts exist for different species which belongs to another kingdom also like even the bacteria has a parasite called bacteriophage which utilizes the resources of the host.

This indicates that every species has some resources which can prove beneficial to another organism in the response of which they become host to a large number of parasites.

Thus, the selected option is the correct answer.

A couple plans to have children until they get a boy, but they agree that they will not have more than four children even if all
DiKsa [7]

Answer:

1.875  is the expected number of children the couple will have.

Explanation:

<em>The probability of an event </em><em>X</em><em> is denoted by </em><em>P(X)</em><em>.</em>

Let assume that X is the number of children to whom the couple will give birth. The couple can have at most <em>four children</em> with the following probabilities.

  • The couple will have one child if the first is boy, thus:

For one child P(X)=1/2=0.50

  • The couple will have two children if the first is girl and the second is a boy, thus:

For two children P(X)=0.5×0.5=0.25

  • The couple will have three children if the first two are girls and the third is a boy, thus:

For three children P(X)= 0.5×0.5×0.5=0.125

  • The couple will have four children if the first three are girls and the fourth is a boy, or if all the four are girls. thus:

For four children P(X) =(0.5×0.5×0.5×0.5)+(0.5×0.5×0.5×0.5)=0.125

<u>Now calculating the expected number of  children the couple will have:</u>

NOTE: Formula is given in the attached pic

Expected number of children = E(X)= (1×0.50)+(2×0.25)+(3×0.125)+(4×0.125)

E(X)= 1.875
