Lakes and rivers constitute _______.a.87% of freshwater

b.a tiny fraction of Earth’s freshwater

c.a majority of Earth’s freshwater

d.a majority of water on earth

Answers

Perhaps surprisingly, lakes and rivers constitute a tiny proportion of the world's total freshwater, so answer (b) is correct. Most of the freshwater on our planet is in fact locked up in ice and glaciers, some 68%. The majority of the rest, 30%, is actually underground, in springs and other groundwater feeders. That leaves just 2% that makes up all the rivers, lakes, ponds and other visible freshwater reservoirs that we see in our day-to-day lives.

One function of the immune system is to attack the foreign cells to protect the body. In organ transplants, how does the immune system take the new organs?

Answers

Answer:

it depends

Explanation:

it it would depend on the blood type or ABO compatibility and if it was the wrong blood type do it attack each other and the person would get sick. but if the blood type matches there is another reason that it may or may not take. that would be called the major histocompatibility complex or MHC. this is basically proteins called cell surface proteins. these proteins are basically the body's way of classifying cells that are of self or non-self. the t cells from an adaptive immune system will look at the MHC and determine whether or not it's for if it's foreign it kills it. if the cell "looks like it belongs ( has compatible blood type and MHC ) then it accepts the transfer.

Analyze the sentence to determine the main clause and the subordinate clause. Then choose the function of the subordinate clause.The Mason-Dixon Line, which is perhaps the most famous border ever established by surveying methods, has been designated a National Historic Civil Engineering Landmark.

1.​Main clause:
A.The Mason-Dixon Line
B.The Mason-Dixon Line, which is perhaps the most famous border ever established by surveying methods
C.The Mason-Dixon Line has been designated a National Historic Civil Engineering Landmark
D.the most famous border ever established by surveying methods has been designated a National Historic Civil Engineering Landmark
E.has been designated a National Historic Civil Engineering Landmark

2.Subordinate clause:
A.which is perhaps the most famous border ever established by surveying methods has been designated a National Historic Civil Engineering Landmark
B.has been designated a National Historic Civil Engineering Landmark
C.which is perhaps the most famous border ever established by surveying methods

3.Subordinate clause functions as a(n):
A.adjective
B.adverb
C.noun

Answers

1. The correct answer is C. The Mason- Dixon Line has been designed as a National Historic Civil Engineering Landmark.

Main clause can also be referred to as independent clause. There is a verb and a subject in it and they express a thought which is complete.

2. Correct answer is C. Which is perhaps the most famous border which is ever established by surveying methods.

Subordinate clause can also be known as dependent clause. It starts with relative pronoun and it has both verb and subject. A complete sentence can not be formed in this combination.

3. The correct answer is adjective.

Subordinate clause functions the same way as adjective.

. Alpha Particles a. What is the mass number of an alpha particle? b. What is the identity of an alpha particle? c. What kind of charge does an alpha particle have?

Answers

Answer:

Alpha particles are usually produced by alpha decay which consisted of two protons and two neutrons.

They are identical to the nucleus of helium-4.

The alpha particle is represented as α or α²⁺. In addition, as it is identical to nucleus of helium, it is also represented as He²⁺.

As it only posses two protons and two neutrons but no electrons, the overall charge of alpha particle is +2.

The mass number of an element refers to the total number of neutrons and protons in the nucleus. Hence, the mass number of alpha particle would be 4
hope it helps you 
an alpha particle is basically a helium nucleus...so it contains 2 protons and 2 neutrons. So atomic mass number is 4..I.e. 2 protons + 2 neutrons
