Explanation:
what is the main function of the skin
Answer:
The skin has three main functions: Protection; Thermoregulation; Sensation.
Explanation:
protection from injury, infection and water loss, regulation of body temperature, elimination of wastes, gathering information and production of vitamin D.Provides a protective barrier against mechanical, thermal and physical injury and hazardous substances. Prevents loss of moisture. Reduces harmful effects of UV radiation. Acts as a sensory organ (touch, detects temperature).Absorption of UV rays, thermoregulation and protection for underlying tissues are all functions of skin.

stomach
heart
Explanation:
circulatory system is an example of an organ system found in the human body .hope it is helpful to you
Answer: Circulatory System
Explanation:
By using the process of elimination, you could tell whether the other options were incorrect.
The heart and stomach are muscular organs so this would not work
The skull is merely a bone structure so this would also be incorrect.

How are traits passed to offspring?
Answer:
Explanation:
Well its all based on DNA which is a really strong part in your body along with every one else and your genes are what tell you what you look like ok so lets say your mom has brown eyes and your dad has blue eyes and your grandma has blue and your grandpa had blue you would be more prone to have blue eyes I hope this will help. :)

What two physical structures help protect the plant and animal against environmental conditions?(11 points) Keep it simple plz
Answer:
Is it any two or is it specific? If so....
Explanation:
Sometimes, both plants and animals can physically change when there is a change in temperature or environment. For example, some plants are really good at surviving in drought-like conditions (cacti). The spikes on the cactus collect water to store for the cactus. Other times, animals (such as the whale or polar bear) have extra thick fur or blubber as insulation when it gets cold. Brrrrrr.

How do different climate zones respond to severe weather?
What challenges does each climate zone face?
How can that climate zone be best prepared for severe weather?
Which climate zone is the safest to live in? Why?
Answer: 1. It just depends on what climate, for example Higher temperatures mean warmer seas, higher sea levels and more moisture evaporating into the atmosphere.
2. More frequent and intense drought, storms, heat waves, rising sea levels, melting glaciers and warming oceans can directly harm animals, destroy the places they live, and wreak havoc on people's livelihoods and communities.
3. Prepare by making sure that everything will stay in the same spot and check the forecast.
4. In North America because there is not a lot of very severe storms
