Answer:
it is convection cells!!
Explanation:
The frequency of a wave does not change as it passes from one medium to another.
What will most likely happen if a light wave moves from the air into a solid?
The speed of the light wave will remain the same.
The wavelength of the light wave will increase.
The wavelength of light will remain the same.
The speed of the light wave will decrease.
Answer:
B. The speed of the light wave will decrease.
Explanation:
The frequency of the waves doesn't change as it passes one medium to another as the speed of the light wave will get decrease. Thus option D is correct.
What is wave frequency?The waves frequency is the number of waves that has fixed oint in the iven amount if time and the unit tomeausre the wave freqiency is hertz.
Where one wave equaks to one fixed point in a second. The moe energy waves have a higher fequency than thoe of the less enegy waves. Thus the speed of the light waves will get decreased.

What do pesticides, heavy metals, hazardous waste, mining for metals, mining for ores, all have in common?
Answer:
pollution of land and water
Explanation:
Pesticides, heavy metals hazardous waste and mining for metals or ores all cause land pollution.
These contaminate the land kill the useful microbes present in the soil. Moreover, when used excessively these chemical enter in our food chain and through into our body and cause various disease. Minamata disease in japan is one such example cause be mercury contamination.
These cause water pollution too. Chemical waste in water give rise to eutrophication and leaching.
What two systems interact to get oxygen to the cells
Answer:
The respiratory and circulatory system functions together to circulate oxygen and blood all through the body. The movement of air takes place in and out of the lungs via the bronchi, trachea, and bronchioles. The movement of blood takes place in and out of the lungs via the pulmonary veins and arteries, which associate with the heart.
The pulmonary arteries mediate deoxygenated blood to the lungs from the heart, and the pulmonary veins carry oxygenated blood to the heart again so that it can be distributed to the rest of the body.
4. Chromosomes are tightly coiled strands of DNA structures that exist in
pairs. Why do they exist in pairs?

Katie designed an experiment using a paint roller pan, sand, and water. The steps of the experiment are listed below.
: Put 3 inches of moist sand on a paint roller pan.
Make a beach by scooping the sand toward the higher portion of the pan.
Pour water into the deeper end of the pan.
Use a straw to blow (simulate wind) on the water for 2 minutes to create waves.
Observe how the sand is displaced by the waves.

How oxygen moves through an ecosystem
Answer:
Plants and animals use oxygen to respire and return it to the air and water as carbon dioxide (CO2). CO2 is then taken up by algae and terrestrial green plants and converted into carbohydrates during the process of photosynthesis, oxygen being a by-product.

The process of natural selection relies on variation within a population or species and occurs when -
A. organisms that exhibit favorable adaptations increase in number compared to those less adapted, and therefor increase their chances of passing along favorable traits to future generations
B. asexual organisms are the result of the process of natural selection
C. organisms that have traits which are not helpful continue to reproduce and carry-on those traits
Answer:
A
Explanation:
by the definition of natural selection more fit organisms survive and reproduce more, propelling population change.
