A North poles attract both like and opposite poles


B South poles attract both like and opposite poles


C Opposite poles repel while like poles attract


D Like poles repel while opposite poles attract

Answers

Answer:

D

Explanation:

All magnets have north and south poles. Opposite poles are attracted to each other, while the same poles repel each other. When you rub a piece of iron along a magnet, the north-seeking poles of the atoms in the iron line up in the same direction. The force generated by the aligned atoms creates a magnetic field.

D. Like poles poles repel each other and attract opposite poles, just think of the phrase “ Opposites attract”

Answers

The answer is B i’m pretty sure! Hope that helped you out! have a great day:)

Answer:

D.

Explanation:

The example of the Gulf Coast dead zone suggests that nonliving factors, such as the amount of nutrients available, significantly affect the survival of organisms in their environment.

Most organisms that were living on or near the ocean floor near the Gulf Coast dead zone could not survive in such low levels of oxygen and either moved to new areas or died off. Scientists are concerned with the size and rapid growth of the dead zone. Preventing the overuse of fertilizers and chemicals that allow excess nutrients to enter the water can help reduce the size of the dead zone.

Answer:   True

Explanation:

Traveling in herds helps fight off predators, since there is strength in numbers. It's only when a deer is separated from the herd is when that animal is in trouble, and has a higher chance of getting eaten.

Males fighting for females is an example of survival of the fittest, so to speak. The female deer decides which male is the strongest which in turn helps pass on strong genes to the next generation.

Both of these traits help lead to successful reproduction and helps the species overall.

The answer is true by the way

if max has a blood type AB and ava is pure bread blood type A, What is the chance their child will have blood type A, B, AB, O

Answers

Ou heredity I love it!

So we have our Punnett square- (sorry about the a. Bad handwriting, and b. Chalkboard) - with max (AB) and Ava (AA) which we would then fill in to look like this- (photo 1)

So it’s 50/50 for their children to have blood type A, and 50/50 for the kids to have blood type AB, and impossible for them to have blood types B, or O.

Which option is an example of a chemical property?


melting point


density


ability to decompose


color

Answers

Answer:
The ability to decompose
Explanation:
A property is a chemical property when it changes the chemical structure of a substance after a reaction.
Density and color are both physical properties.
Even though melting point may seem like a chemical property, when something melts, only the physical state changes, and the chemical structure does not change, and therefore, is a physical property.
The ability to decompose is a chemical property. When something decomposes, the chemical structure of many molecules change, and therefore, is classified as a chemical property.
