What is temperate coniferous forest?The World Wide Organization for Nature defines temperate coniferous woodland as a terrestrial biome. Temperate coniferous forests can be found mostly in locations with warm summers and chilly winters, and their plant life varies. Some are dominated by needleleaf trees, while others are dominated by broadleaf evergreen trees or perhaps a mixture of both tree species.
Temperate coniferous forests can be found along the coasts of places with moderate winters and copious rainfall, as well as inland in drier climes or montane locations. These woods are home to a variety of tree species, include pine, cedar, fir, among redwood. Temperate coniferous forest experience cool winters and have warm summers.

What impact did the Spanish have on the region of South America?
In two to three sentences, include two examples of how the Spanish impacted the region of South America.
Answer:
The Spaniards practically went to war with the native Americans in South America, such as the Inca. They also brought diseases to South America. Diseases like smallpox.

What is the most likely adaptation for a rabbit which once lived in the snow but now lives in shrubs and rocks due to increased global temperatures?
They will see an increase in fur production
They will become better swimmers
They will grow longer ears
Their coats will become darker due to natural selection
The most likely adaptation of a rabbit that moves from snow to shrubs and rocks would be a darker coat color due to natural selection.
What is adaptation?It is the physiological and or morphological changes that occur in organisms that enable them to survive in their environments.
A rabbit that moves from living in the snow to living in shrubs and rocks does not need to produce more fur to survive as the temperature will be higher than in the snow.
Also, such a rabbit does not need to become a better swimmer since it is not living in the water. A longer ear also has no bearing in adapting it to its new environment.
A darker coat color, however, will conceal it from predators and give him a selection advantage.

A praying mantis eats a bee.
Tell which type of relationship it is: mutualism, predation, parasitism, competition, or commensalism. Give details on why.
Try for 2 sentences:
I think a praying mantis eating a bee is an example of....
I think this because...
Answer:
I think a praying mantis eating a bee is an example of predation. I think this because the praying mantis stealthily hunts its preys, like the bee, in order to kill eat for food.
Explanation:
"Predation" refers to the killing of another living organism in order to prolong the life of the "predator" (hunter) and to end the reproductive life of the "prey" (the one being consumed). The praying mantis is popularly known for being a deadly predator because it feeds on several insects (as its prey), including the bees. They are said to also feed on wasps, moths, mice, frogs, rodents and even snakes.
It kills the bees in order to consume them so it can prolong its reproductive life. It then stops the reproductive life of the bees. Clearly, the type of relationship here is "predation."
I think a praying mantis eating a bee is an example of predation.
I think this is because the praying mantis which is a predator consume the prey which is the bee most times in a defensive manner.
Predation is a biological relationship in which a predator kills or consume it's prey.
It's occur majorly in canivorous animals that consume flesh or other animals.
The predators consume the prey as food and as a form of defensive means from been attacked by the prey.
In this relationship, energy is transfered from the prey which is the bee to the praying mantis.
Therefore, the relationship that occur between praying mantis and bee is predation.

You observe that the hair on your head stands up when a charged balloon is brought near without touching your head. Based on this observation, you write down the following question and steps to an experiment.
Can two charged objects be attracted to each other without touching?
Step #1: Bring the charged balloon 10 cm from your head.
Step #2: Charge the balloon by rubbing it against a cloth.
Step #3: Record your observation.
Step #4: Bring the charged balloon 5 cm from your head.
Step #5: Record your observation.
What revision could you make to improve the experiment?
Remove the fifth step, you do not need to make multiple observations in an experiment.
Reverse the first two steps so that you charge the balloon before you bring it close to your head.
Reverse the second and third steps so you record your observation before you charge the balloon.
Swap steps two and four, you do not need to charge the balloon until the end of the experiment.
Answer:
yes it can be attracted without touching The electric force is a non-contact force. Any charged object can exert this force upon other objects - both charged and uncharged objects.
