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
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.
Is this a chemical reaction?

Thick bark
Answer:
Flexible stems
Explanation:
Due to a vine's flexible stems, it finds a strong plant to grow on, slowly growing around it to get nutrience and light from the spot. without it, it would just sit on the forest floor.

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.
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.

They grow in number.
They move to new locations.
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.
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.

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.

What environmental change happens when the number of prey in a certain area decreases?
Climate change
Increased predators
Pollution
Reduced space
Question:
What environmental change happens when the number of prey in a certain area decreases?
Answer:
C) Pollution.
In an ecosystem, there is an increase in the number of predators when the number of prey in a certain area decreases.
What is an ecosystem?Ecosystem is defined as a system which consists of all living organisms and the physical components with which the living beings interact. The abiotic and biotic components are linked to each other through nutrient cycles and flow of energy.
Energy enters the system through the process of photosynthesis .Animals play an important role in transfer of energy as they feed on each other.As a result of this transfer of matter and energy takes place through the system .Living organisms also influence the quantity of biomass present.By decomposition of dead plants and animals by microbes nutrients are released back in to the soil.
