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.

Pick the correct relationship between magnetic poles

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”

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.
Ability to decompose

Marine organisms trying to live in the water may not get enough oxygen to survive. Based on this description, which of the following is true?
A.
The supply of any nonliving factor supports or limits growth of all organisms in an ecosystem in the same way.
B.
The number of organisms of each type in an ecosystem depends on living factors but not on nonliving factors.
C.
Living factors, such as the number of producers present, play the largest role in the survival of organisms in an ecosystem.
D.
Nonliving factors, such as the amount of nutrients available, significantly affect the survival of organisms in their environment.

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.

Select an animal from that you may know about and explain how physical and behavioral adaptations increase the chances of successful reproduction. Use evidence and scientific reasoning to support your response.

Answers

an animal could be the toucan, overtime it grew a longer beak in order to access food that other birds couldn’t get. this increases the chances of successful reproduction because being able to survive longer than other birds to the beak and providing food for the babies, they can reproduce multiple times

The cheetah (Acinonyx jubatus) will be the subject of my discussion. Cheetahs are the world's fastest land mammals, and they have evolved in both physical and behavioural ways to improve their chances of having offspring.

What is the behavior of  A Cheetah ?

First off, cheetahs have a highly effective circulatory system that includes bigger hearts and lungs, as well as a surplus of capillaries and red blood cells to carry oxygen to their muscles. This gives them the ability to pursue prey at speeds of up to 75 mph, increasing their likelihood of catching it and providing food for themselves and their young.

Second, cheetahs have a distinctive fur pattern that makes it simpler for them to blend into their surroundings and sneak up on their prey.and draw near enough for an effective assault. They can sprint rapidly and effectively because to their long legs and big feet.

Last but not least, cheetahs have a variety of behavioural modifications that improve their chances of having offspring. For instance, they create social groupings where the mothers look after the babies while the males go food hunting and guard the young from predators.

They also have a strong sense of smell that allows them to detect potential prey from far away. They get an edge in hunting and have a better probability of feeding their offspring as a result. In summary, cheetahs have a variety of morphological and behavioural adaptations that raise their likelihood of having offspring. Among these modifications is an extremely effective cardiovascular system.
