Write a few sentences about how being small helps cells survive, and being made of many small cells help large organisms maintain homeostasis?
Answer:
It is important for the cell to be able to bring necessary nutrients immedriately where it needs to and to be able to dispose of harmful byproducts of the cell process. It is equally important to be able to regulate water concentration.
Answer:
For the first question, you have to first understand how cells work. Cells transport nutrients and water through their cell membrane, and it's their only way of transporting things they need in and out of their interior. Hence, a larger surface area would be best for cells to survive.
You might ask, but then why wouldn't it be better for cells to be bigger if a larger cell membrane is beneficial to their survival? After all, as the cell gets bigger, their cell membrane gets bigger too!
Unfortunately, you'd be forgetting one thing: the insides of the cell, otherwise known as the volume of the cell, grows too. So, it becomes a mathematical question at this point: imagine a cube. If you doubled it's side length, your surface area would grow by 4 times ([tex]2x \cdot 2x = 4x^{2}[/tex]), and your volume would grow by 8 times! ([tex]2x \cdot 2x \cdot 2x = 8x^{3}[/tex])
Hence, if the cell got bigger, it's volume would grow faster than the surface area, and the cell would start to build up carbon dioxide and other waste materials.
This is the main reason why being small helps cells survive. Of course, there are many other reasons, like compactness, efficiency and survivability, but this is the main reason.
Of course, if you're smart, you'd have already discovered one thing: this is exactly the reason for your second question as well. Since a large organism being made of one or few large cells would greatly decrease surface area-to-volume ratio, the efficiency would plummet and the large organism would die. Hence, many small cells would help large organisms maintain homeostasis.

Answer:
It's possible.
Explanation:
It said if they were nearly as smart as humans. They never said if they were as capable as Humans. Naturally, some would be smarter than others so some might be able to live here but others might have to have their own country. So, it is likely that some Neanderthals will be able to live in modern society, though not all.

What causes the sinking of water in the northern Atlantic Ocean, which helps to drive the Ocean Conveyor Belt?
a.) The high salinity from the south warms and becomes less dense.
b.) The high salinity from the south cools and becomes denser.
c.) The low salinity from the south gains salt and becomes denser.
d.) The low salinity from the south loses salt and becomes less dense.
Answer:
the answer
proberbaly C or B
Answer:it's B or C
Explanation:
In cold regions, such as the North Atlantic Ocean, ocean water loses heat to the atmosphere and becomes cold and dense. When ocean water freezes, forming sea ice, salt is left behind causing surrounding seawater to become saltier and denser. Dense-cold-salty water sinks to the ocean bottom.

5. What is the response of an ectotherm, such as a lizard, when it encounters cold temperatures?
It will move to a warmer spot.
It will remain in the cold environment.
It will run toward the stimulus.
It will become hungry.
Answer: It will move to a warmer spot.
Explanation:
An ectotherm will move to a warmer spot if they found themselves in cold temperatures because they are not tolerating good cold temperatures. If they do not have any other options they will run toward the stimulus which means that they will try to bury themselves and hide from cold temperatures and in that way they will have to remain in the cold environment.

Energy can change in two different ways. It can undergo a transfer, or it can undergo a transformation. For each of these examples of how energy is changed, write the correct answer in the blank.
In photosynthesis, solar energy undergoes a _______ when it changes from light energy to chemical energy. When the sun warms Earth’s surface, thermal energy is ___________ to land and water.
Answer:
Energy transfer is the movement of energy from one location to another. For example, when electricity moves from a wall plug, through a charger, to a battery.
Energy transformation is when energy changes from one form to another – like in a hydroelectric dam that transforms the kinetic energy of water into electrical energy.
While energy can be transferred or transformed, the total amount of energy does not change – this is called energy conservation.

Which of these is another way to write Newton's second law of motion? ...
What is it called when light changes direction after leaving a lens? ...
How do you calculate density?What kind of waves are present during an earthquake?
Answer:
1.The two main types of waves are body waves and surface waves. Body waves can travel through the earth's inner layers, but surface waves can only move along the surface of the planet like ripples on water. Earthquakes radiate seismic energy as both body and surface waves.
2. As the combustible materials burn, some of the chemical energy is transformed into heat energy, and some is transformed into light energy. Light energy, also known as radiation or electromagnetic energy, is a type of kinetic energy that takes the form of visible light waves, such as the light from a match
3. Newton's second law of motion is F = ma, or force is equal to mass times acceleration.

In a certain species of flowering plant, the purple allele P is dominant to the
Yellow allele p.
A student performed a cross between a purple-flowered plant and a
yellow-flowered plant. When planted, the 146 seeds that were produced from the
cross matured into 87 plants with purple flowers and 59 plants with yellow
flowers.
Calculate the chi-square value for the null hypothesis that the purple-flowered
parent was heterozygous for the flower-color gene. Give your answer to the
nearest tenth.
Answer:
3.4
Explanation:
If the purple flower is heterozygous:
Pp x pp
Pp Pp pp pp
the expected ratio of purple flower offspring to yellow flower offspring would be 50:50.
Chi square = [tex]\frac{(O - E)^2}{E}[/tex] where O = observed frequency and E = expected frequency.
phenotype O E Chi square
purple 87 73 [tex]\frac{(80-73)^2}{73}[/tex] = 0.67
yellow 59 73 [tex]\frac{(59-73)^2}{73}[/tex] = 2.68
Total = 0.67 + 2.68 = 3.35 to the nearest tenth = 3.4
Degree of freedom = 2 - 1 = 1
Critical Chi square value (alpha = 0.05) = 3.84
SInce the critical Chi square value is greater than the calculated value, the null hypothesis is accepted.
