Plz help this is due in 5 mins Which interaction contributes to the greenhouse effect?

Gases in the atmosphere absorb heat.

Dust particles scatter and reflect light from the Sun.

Green visible light is trapped in Earth’s atmosphere.

Light travels through a thick part of the atmosphere at sunrise and sunset.

Which process causes Earth’s surface to warm?

the conduction of heat by air above the Earth's surface

the radiation of the Sun’s electromagnetic waves

the convection of warm air from the atmosphere

the reflection of electromagnetic waves off bodies of water

How do ice and water on the ground affect incoming solar radiation?

They filter 22 percent of solar radiation that reaches the surface.

They reflect 4 percent of solar radiation that reaches the surface.

They absorb 100 percent of solar radiation that reaches the surface.

They scatter 5 percent of solar radiation that reaches the surface.

How do the magnetic and electrical components of electromagnetic waves travel in relation to each other?

at right angles

toward each other

in a circular motion

parallel to each other

Which type of heat transfer causes a person sitting by the fire to feel warm?

absorption

conduction

convection

radiation

Which is a type of heat transfer that causes the air at the top floor of a building to be hotter than the air at the bottom floor of a building?

conduction

convection

radiation

reflection

Why is the sky orange and red at sunrise and sunset?

Gases absorb orange and red light.

Blue wavelengths are absorbed by the atmosphere.

The thick atmosphere scatters all but longer wavelengths.

Only short wavelengths are radiated from the Sun in the morning and evening.

What percent of solar radiation is filtered by clouds and may cause sunburn on cloudy days?

3 percent

14 percent

22 percent

31 percent

i think it is dna, i'm not totally sure but i think it might be.

question#1

ans:

cell is the basic unit of organization of all living things. cells are often called the building block of life and it is the smallest unit of life. the study of cell is called cell biology. cell consists of cytoplasm enclosed within membrane, which contain bio-molecules such as proteins and nucleic acid.

two third of cell is water, which means that two-third of your whole body is water. the rest is the mixture of molecules, mainly proteins, lipids and carbohydrates.

question#2

ans:

organ:

an organ is a group of tissues specialized to form a functional unit. an example is the heart in animals.

organ system:

an organ system is a group of several organs whose functions are synchronized to release an effective action in a living organism. an example is digestive system.

question#3

different systems perform different function at tissue level. for example, the respiratory system facilitates breathing. in the alveoli tissue of the lungs, the exchange of oxygen and carbon dioxide molecules between the air and the bloodstream occurs by passive transport, so that oxygen is taken in and carbon dioxide and water are removed. different systems of the body carry out different functions. for example, your digestive system is responsible for taking in and processing food, while your respiratory system working with your circulatory system is responsible for taking up oxygen and getting rid of carbon dioxide.

question#4

different systems perform different function at tissue level. for example, the respiratory system facilitates breathing. in the alveoli tissue of the lungs, the exchange of oxygen and carbon dioxide molecules between the air and the bloodstream occurs by passive transport, so that oxygen is taken in and carbon dioxide and water are removed. different systems of the body carry out different functions. for example, your digestive system is responsible for taking in and processing food, while your respiratory system—working with your circulatory system is responsible for taking up oxygen and getting rid of carbon dioxide.

question#5

our body works because of the interactions that happen between organs and organ systems.  

for example:  

the heart to regulate blood flow throughout the body. the blood carries oxygen and nutrients to the cells and carries carbon dioxide and waste away from the cells. body systems work together in maintaining a constant internal environment. when this balance is disrupted, the body systems may not function properly, and human health can suffer.   you start to feel bad.
