14. Karim brings a chair from the backyard into his house and is going to stack it on top of another chair. Both chairs are the same size and have the same number of molecules. The diagram above shows the chairs before they touch. Use the information in the diagram to answer the question.
How does the temperature of the bottom chair compare with the temperature of the top chair before the chairs touch? What will happen after the chairs have been touching for a while?
a Before the chairs touch, the bottom chair is cooler than the top chair. Once the chairs are touching, the top chair will transfer kinetic energy to the molecules in the cooler bottom chair until both chairs reach the same temperature, which will be in between their starting temperatures.
b Before the chairs touch, the bottom chair is hotter than the top chair. Once the chairs are touching, the bottom chair will transfer kinetic energy to the molecules in the cooler top chair until both chairs reach the same temperature, which will be in between their starting temperatures.
c Before the chairs touch, the chairs are different temperatures. Once the chairs are touching, both kinetic energy and cold energy will transfer between the molecules in the two chairs until both chairs reach the same temperature, which will be in between their starting temperatures.
d Before the chairs touch, the bottom chair is hotter than the top chair. Once the chairs are touching, the cooler top chair will gain kinetic energy until the molecules in both chairs have an energy of 35, because hotter things increase the temperature of cooler things.

Explain the three parts of the cell theory in your own words.
please & TYSM!!!
Answer:
Explanation:
The cell theory basically just tells you what cells are and why they exist.
There are three main parts and those are;
1;All living things are made up of cells.
This basically means that every living thing in the world has a cell . If they don't have a cell ,then they are not living.
2; New cells are created by old cells and they divide into two
This means that when when old cells start to decay new cells start to form and replicate by splitting into two cells.
3.Cell are the basic unit for life.
This means that without cells we can't live. Life started with one single cell.

Select the sentence from the passage that describes incomplete dominance.
“1(These flowers are red and white because they have one red parent and one white parent.)1 (2 This is due to both alleles being expressed at the same time.)2 (3 But these pink flowers also have one red parent and one white parent.3) (4 Blending of colors occurs from mixing a dominant and recessive allele for an inherited trait".)4
1, 2 , 3, or 4?
Answer:
4
Explanation:
you answer is 4 because it shows how incomplete dominance works, and that the blending between the two colors, is not codominance.
Suppose a sound wave with a frequency of 444 Hz combined with a sound wave with a frequency of 436 Hz. How many beats would you hear in one second?
Answer:
Explanation:
The sound wave has a wavelength of 0.773m.
Explanation:
To solve this problem we have to use the wave equation that is given below:
frequency of sound wave=444 Hz-436 Hz =8 Hz
Therefore, an individual will hear 8 beats per second.
What do you mean by frequency of sound waves?Frequency is the rate at which current changes direction per second. It is measured in hertz (Hz), an international unit of measure where 1 hertz is equal to 1 cycle per second. Hertz (Hz) = One hertz is equal to one cycle per second.
Frequency, sometimes referred to as pitch, is the number of times per second that a sound pressure wave repeats itself.
The number of vibrations made by a particle of the medium in one second is called the frequency of a sound wave.

which population is most likely to survive? (PLEASE ANSWER ASAP AND CORRECTLY, I WILL AWARD BRAINLIEST) (image below)
Populations 1 and 2 will most likely survive.
Populations 2 and 3 will most likely survive.
Only Population 2 will survive because it is the only population with variation.
All the populations will survive because the seals will change the thickness of their blubber if they need to.
Answer:
populations 1 and 2 will most likely survive.
Explanation:
so here's my thinking- seeing as how population 1 only has seals with thin blubber they will automatically survive because they won't need to adapt to the environment. but population 2 has both thin and thick blubbered seals and seeing as how the thick blubbered ones will most likely just die out the thin blubbered ones will 'take over'
good luck :)
i hope this helps
have a nice day !!
Answer:
Populations 1 and 2 will most likely survive.
Explanation:
If the water is changing to warm, the seals with no blubber wont get too hot. The thick seals will overheat.

Read the passage. Then explain the ways humans have influenced the traits in corn plants and the impacts each biotechnology has had
Many of the types of corn found in grocery stores were originally bred for their taste and productivity. But these varieties are often threatened by pests. This makes it harder for farmers to produce enough corn.
Scientists have used genetic engineering to make GMO corn plants that are resistant to pests. In one type of GMO plant, they added genes from bacteria that live in soil. The genes let the GMO plants produce a bacterial protein that kills certain insects.
Answer:
they have influenced it through genetic engineering
Explanation:
Answer:
The scientists used genetic engineering to manipulate the genes of the corn plant so that they are resistant to pests. A negative impact this biotechnology has is that the genes that help the corn plant resist pests also creates bacteria that kills certain insects.

3. What season is it in the Southern Hemisphere in Picture A? Why?
Look at the diagram of the hydrologic cycle, and use it to help you to write a paragraph that explains how a droplet of water that falls as rain can move through the atmosphere, the biosphere, the geosphere, and the hydrosphere. Be specific as you explain the processes (evaporation, condensation, transpiration) that occur because of interaction between Earth’s spheres. In your response, be sure to...
Give the state of matter that water is in as it moves through Earth’s systems
Describe what processes occur to change water from one state of matter to another
Explain how interactions between Earth’s spheres keep water cycling between them
Answer:
The Earth has a finite amount of water. The water that is here today is the same water that will be here in 20 or even 20 million years’ time. So, if all living things use water, how is it that we don’t use up all our water? The answer is that water is constantly recycled through the Earth’s system through a process called the water cycle.
Dynamic and complex: the global water cycle
Water in the Earth system is influencing all aspects of life on Earth. Pathways, storage, transfers and transformations have an effect on the global climate and human welfare. Within this interactive 4 scientists talk about some of the complex aspects of the water cycle.
To use this interactive, move your mouse or finger over any of the labelled boxes and click to obtain more information.
The water cycle encompasses a number of processes that circulate water through the Earth’s subsystems. Water evaporates from within soils and through vegetation and from bodies of water (such as rivers, lakes and oceans). This evaporated water accumulates as water vapour in clouds and returns to the Earth as rain or snow. The returning water falls directly back into the oceans, or onto land as snow or rain. It soaks into the soil to move into the groundwater or runs off the Earth’s surface in streams, rivers and lakes, which drain back into the oceans. The water may be taken up by plants and returned to the atmosphere through processes like transpiration and photosynthesis. Water may also be returned to the atmosphere through the combustion of plants in fossil fuel.

The dynamic water cycle
In this video, four New Zealand scientists – Dave Campbell, Louis Schipper, David Hamilton and Keith Hunter – talk about how only a small percentage of the Earth’s water is freshwater, and of that small percentage, only a fraction is available for human use.
Water and the atmosphere
Water enters the atmosphere through evaporation, transpiration, excretion and sublimation:
Transpiration is the loss of water from plants (via their leaves).
Animals excrete water by respiration and by passing urine.
Sublimation is when ice or snow transforms directly into water vapour without going through a liquid phase (i.e. they do not melt).
Water commonly occurs in the atmosphere in the form of water vapour. If it cools down, it can condense, accumulating in clouds. As the clouds grow, they become heavier and can fall back to the Earth as precipitation (rain, snow, hail or sleet) or re-evaporate back into vapour.
Water and the biosphere, hydrosphere and geosphere
When water returns to Earth, it can either enter the hydrosphere or the geosphere.
Water vapor becomes liquid with the condensation process where water comes from lakes and rivers to evaporate into the atmosphere. Water is released from living organisms by the process of transpiration.
What is Condensation?Condensation is defined as the change of state of a substance from the gas phase to the liquid phase, and is the opposite of vaporization. The term mainly refers to the water cycle.
It is the process through which the physical state of matter changes from gaseous state to liquid state, such as condensation occurs when water vapor which is in gaseous form in the air, when it comes in contact with a cold surface becomes liquid .
When water in the air comes in contact with a cold surface, it condenses in the form of water droplets. Evaporation is the opposite reaction to condensation.
Thus, water vapor becomes liquid with the condensation process where water comes from lakes and rivers to evaporate into the atmosphere. Water is released from living organisms by the process of transpiration.
