Answer:
An isotonic solution is one that has the same osmolarity, or solute concentration, as another solution. If these two solutions are separated by a semipermeable membrane, water will flow in equal parts out of each solution and into the other.
Answer:Isotonic solutions contain equal concentrations of impermeable solutes on either side of the membrane and so the cell neither swells nor shrinks.

is something that RESTRICTS the growth of a population in an area and prevents it from going past a certain amount
Answer:
Limitations in the niche or habitat, like disponible food or oxygen saturation.
Explanation:
The limitation of food is the most common way to limit the growth of a population, because without food, the individuals will die in a intraespecific competition.
In other side, the oxygen saturation is a more common way to limit growth aquatic organisms, whom needs O2.
Food and oxygen saturation are into the niche of a living being. The niche is the way a living being lives, which means that a niche envolves the disponible food, places for reprodution, etc.
All what limited the growth of a specie is inside its ecological niche.
Besides that, the habitat is the place where the organisms leaves. The possible activity of a niche depends on the habitat it lives.
Answer:
Limiting Factors
Explanation:
Limiting factors are both biotic and abiotic influences that restrict the growth of a population
Examples of abiotic limiting factors include the physical space that organisms occupy (is it big enough?) and the amount of sunlight (is there enough sunlight for plants to efficiently perform photosynthesis to support the consumers of the ecosystem.
Examples of biotic limiting factors include the availability of food (is there a large enough food source to sustain a large population?) and the presence of organisms that compete with the resources
When the moon's shadow covers part of the earth it is called
a.Eclipse
b. Full moon
c.New moon
d.All of the above
Answer:
A
Explanation:
The light from the sun is blocked by the moon, causing the earth to appear dark during the day.
Answer:
a. Eclipse
Explanation:
When the moon comes between the Earth and the Sun, it blocks the sunlight from reaching the Earth's surface and creates a shadow. This is called an eclipse.
Full moons and new moons are just names for different moon phases. A full moon is when the Sun's light is reflected off the entire surface of the moon which gives it a "full" appearance, while a new moon is the exact opposite and the moon will be completely dark. Neither of these cast a shadow onto the Earth.
What is the relationship between kinetic energy and thermal expansion?
Answer:
These molecules are always in motion and higher temperature gives them more energy and they vibrate more rapidly and hence have higher kinetic energy. One effect of this rapid motion (high kinetic energy at higher temperatures) is the expansion observed, when we heat a substance.
Hope this helps.
describe the steps in the rock cycle
Answer:
The three main rock types are igneous, metamorphic and sedimentary. The three processes that change one rock to another are crystallization, metamorphism, and erosion and sedimentation. Any rock can transform into any other rock by passing through one or more of these processes. This creates the rock cycle.
How is nuclear energy related to the nucleus of an atom?
Answer:
Nuclear energy is energy that comes from the nucleus (core) of an atom. Atoms are the particles that make up all objects in the universe. Atoms consist of neutrons, protons, and electrons. Nuclear energy is released from an atom through one of two processes: nuclear fusion or nuclear fission.

1. Define Chemosynthesis?
the synthesis of organic compounds by bacteria or other living organisms using energy derived from reactions involving inorganic chemicals, typically in the absence of sunlight.
2. List some organisms that undergo Chemosynthesis?
Chemoautotrophs, organisms that obtain carbon from carbon dioxide through chemosynthesis, are phylogenetically diverse, but also groups that include conspicuous or biogeochemically-important taxa include the sulfur-oxidizing gamma and epsilon proteobacteria, the Aquificae, the methanogenic archaea and the neutrophilic.
3. Which organisms conduct photosynthesis?
Most plants, most algae, and cyanobacteria perform photosynthesis; such organisms are called photoautotrophs. Photosynthesis is largely responsible for producing and maintaining the oxygen content of the Earth's atmosphere, and supplies most of the energy necessary for life on Earth.
4. Define photosynthesis
the process by which green plants and some other organisms use sunlight to synthesize foods from carbon dioxide and water. Photosynthesis in plants generally involves the green pigment chlorophyll and generates oxygen as a byproduct.
5. Type out the chemical equation of photosynthesis?
The photosynthesis equation is as follows: 6CO2 + 6H20 + (energy) → C6H12O6 + 6O2 Carbon dioxide + water + energy from light produces glucose and oxygen.
Answer: 1?
In biochemistry, chemosynthesis is the biological conversion of one or more carbon-containing molecules (usually carbon dioxide or methane) and nutrients into organic matter using the oxidation of inorganic compounds (e.g., hydrogen gas, hydrogen sulfide) or ferrous ions as a source of energy, rather than sunlight, as in photosynthesis. Chemoautotrophs, organisms that obtain carbon from carbon dioxide through chemosynthesis, are phylogenetically diverse, but also groups that include conspicuous or biogeochemically-important taxa include the sulfur-oxidizing gamma and epsilon proteobacteria, the Aquificae, the methanogenic archaea and the neutrophilic iron-oxidizing bacteria.
2? Why is chemosynthesis important? Chemosynthetic deep-sea bacteria form the base of a varied food web that includes shrimp, tube- worms, clams, fish, crabs, and octopi.
3? Most plants, most algae, and cyanobacteria perform photosynthesis; such organisms are called photoautotrophs. Photosynthesis is largely responsible for producing and maintaining the oxygen content of the Earth's atmosphere, and supplies most of the energy necessary for life on Earth.
4? the process by which green plants and some other organisms use sunlight to synthesize foods from carbon dioxide and water. Photosynthesis in plants generally involves the green pigment chlorophyll and generates oxygen as a byproduct.

HELP WHICH ONE?
A study was conducted to understand the factors controlling the rate at
which molecules or ions travel across cell membranes. An artificial
membrane was created that was composed of a phospholipid bilayer only.
The speed at which various substances crossed this membrane was
measured. Some substances can pass through an actual cell membrane
much faster than they passed through the artificial membrane in this study
Which of the following statements best explains this finding?"
Actual cell membranes have a much thicker phospholipid bilayer than the artificial
membrane does
Actual cell membranes have a variety of proteins embedded in the membrane that are
absent in the artificial membrane
Hydrophobic substances spend more time between the two layers of phospholipid in
the artificial membrane than they do between the layers in an actual membrane
Hydrophilic substand spend more time attached to the polar region of the
phospholipids in the artificial membrane than they do attached to the polar region of
the phospholipid in an actual membrane

number of electrons = number of protons
The Gulf Stream is an ocean current of warm water that flows from the Caribbean Sea up the eastern coast of North America before crossing over to the British Isles. The current brings warm water and air northward. Scientists are concerned that global warming will cause polar ice to melt and form a cold water current that blocks the Gulf Stream. Infer possible climatic effects resulting from substantial quantities of northern polar ice melting.
Answer:
Explanation:
Due to rise temperature leading to melting of ice more water flows to the seas from glacies and ice caps increasing the volume of water in the ocean. This has lead to increase in average global sea level between four and eight inches.
It leads to salt water intruding into freshwater this affect sources of drinking water and makes raising crops problematic.
It leads to increase in population on the coast as people moved far away from the shore due to erosion.
Explain the connection between a molecule of water and atoms.

What can you inter about the growth of the seed type pictured in the graphs below?
a. More seeds grow with more light.
b More seeds grow with less light.
C. The seeds grow faster with more light.
d Tinht has no effect on seed growth.
Answer:
The 2 graphs are pretty much showing the same effects on the dependent variable, so I would say that light has no effect on seed growth.
On the other hand, just by thinking logically, Seeds are usually underground before germination, so light wouldn't really affect them much.
So, light wouldn't really affect them
