Answer:

A type B+ patient can receive blood from:

(a) a type B+ blood sample

(b) a type O+ blood sample

(d) a type O- blood sample

Explanation:

There are four blood types known as A, B, AB and O

Different blood types have proteins known as antigens which are attached to them. Type A has antigen A, type B has antigen B, type AB has both antigens A and B, while type O has neither A nor B antigens.

The human immune system naturally produces antibodies against antigens that are not found in its own blood, hence blood type A produces antibodies B antigens, type B produces no antibodies against antigen A or B and type O produces antibodies against antigens A and B. Hence, a type A patient can only receive a type A or type O blood; a type B patient can only receive a type B or O blood; a type AB patient can receive a type A blood, a type B blood or a type O blood; a type O blood can only receive a type O blood.

Rhesus is an antigen that occurs naturally in the blood of some humans (85% statistically). Humans having this antigen are rhesus positive and bear the "+" sign in front of their blood type, while a rhesus negative human bears the "-" sign in front of their blood type. A rhesus + patient can receive a rhesus + or rhesus - blood but a rhesus - patient can only receive a rhesus - blood.

Therefore, a type B+ patient can only receive blood from:

(a) a type B+ blood sample

(b) a type O+ blood sample

(d) a type O- blood sample

What is true about electromagnetic waves from the sun? A. They travel through space without a medium B. They consist of electric

Cloud [144]

Answer:

Option A) is correct.

Explanation:

Electromagnetic waves refer to waves that are created due to vibrations between a magnetic field and an electric field.

Electromagnetic waves do not require a medium to travel through space without a medium. Electromagnetic waves can travel through air, vacuum of space and solid materials.

So,

Option A) is correct.

An air mass forms over the North Pole region describe what you think the temperature and humidity of this air mass will be like?

Answer: hope this helps :)

The motion of air mass motion is usually based upon the air flow in the upper atmosphere. As the jet stream changes intensity and position, it affects the motion and strength of air masses. Where air masses converge, they form boundaries called "fronts".

3-D view of a cold front.

Fronts are identified by change of temperature based upon their motion. With a cold front, a colder air mass is replacing a warmer air mass. A warm front is the opposite affect in that warm air replaces cold air. There is also a stationary front, which, as the name implies, means the boundary between two air masses does not move.

The motion of air masses also affects where a good portion of precipitation occurs. The air of cold air masses is more dense than warmer air masses. Therefore, as these cold air masses move, the dense air undercuts the warmer air masses forcing the warm air up and over the colder air causing it to rise into the atmosphere.

So, fronts just don't appear at the surface of the earth, they have a vertical structure or slope to them as well. Warm fronts typically have a gentle slope so the air rising along
