Animal cells are placed in an isotonic solution. THEN, additional amounts of solute are added to the solution. What happens to the cells
Answer:
The animal cell will shrink due to loss of water to the external solution
Explanation:
An isotonic solution is that solution which has equal concentration with its external environment. Hence, no net movement of water occurs in an isotonic solution since there is no concentration gradient. Therefore, if an animal cell is placed in an isotonic solution at first, no net movement of water occurs because the intracellular and extracellular concentrations are at equilibrium.
However, if more solutes are added to the solution, it makes the solution HYPERTONIC to the cell i.e greater in concentration. This creates an osmotic gradient and causes water to move out of the animal cell into the solution in accordance to osmotic principles (movement of water from a low concentration of solute to high concentration of solute). This causes the animal cell to likely SHRINK.
Three students were working on a drawing of the water cycle for a class project. They each had different ideas about what needed to be in their drawing to show the water cycle. This is what they said
Who do you agree with the most?
A)Van: There always has to be a body of water in a water cycle diagram. It doesn't have to be an ocean. It can be an ocean, lake, river, pond, stream, or other body of water
B)Lamar: A water cycle diagram doesn't have to have a body of water. We can draw it without an ocean, lake, river, and, steam, or other body of water
C) Rema: There has to be an ocean in a water cycle diagram.
Answer:
I agree with A, Van.
Explanation:
I agree with Van because I have personally seen water cycle diagrams without the ocean. Another reason why I agree with Van is because in some areas in the world, the ocean isn't anywhere near close to said areas.

contrast ionic covalent bonds. what happens to the valence electrons how does it affect the elements/compounds
Answer:
The number of electrons in an atom's outermost valence shell governs its bonding behaviour. Elements whose atoms have the same number of valence electrons are grouped together in the Periodic Table. ... To form a covalent bond, one electron from the halogen and one electron from another atom form a shared pair.
How much carbon-14 remains at the end of five half-lives? Explain your
reasoning.
Answer:
1/32 of the original amount.
Explanation:
Each half-life is half of the prior life so:
1st half-life = 1/2
2nd half-life = 1/4
3rd half-life = 1/8
4th half-life = 1/16
5th half-life = 1/32
Answer: 1/32
Explanation: because you ask how much carbon-14 remains at the end of five half-lives! and you told me Explain my reasoning. your welcome
Why does much of East Africa have cooler
temperatures than other regions?
A The region sits at a higher elevation.
B The region has enormous grasslands.
C The region benefits from deepwater lakes.
D The region is divided by a series of
rift valleys.
Answer:
A. The region sits at a higher elevation.
Explanation:
The east coast of Africa would have a cooler climate than the western coast because of the tilts on the Earth's axis. Global climate is shaped by many factors, including solar energy trapped in the biosphere, latitude, and the transport of heat by winds and ocean currents.Cells are divided into which two major groups?
According to the cell theory, the cell is the basic unit of life. All living organisms are composed of one or more cells. Based on the organization of their cellular structures, all living cells can be divided into two groups: prokaryotic and eukaryotic (also spelled procaryotic and eucaryotic).
A cell's initial classification into one of two groups depends on whether it has a nucleus. In contrast to eukaryotic cells, which have a nucleus where the genetic material is segregated from the cytoplasm, prokaryotic cells (bacteria) do not have a nuclear envelope.
In prokaryotes, the DNA (chromosome) is not contained in a membrane bound nucleus; instead, it is in direct contact with the cellular cytoplasm.
A nuclear membrane, also known as a nuclear envelope, separates the DNA from the rest of the cell in eukaryotes, which have compact chromosomes as its form of DNA.

What do ocean waves and
currents have to do with energy waves and
electrical currents?
Answer:
they are both waves and currents
Explanation:
gl studyinggg
Ocean waves, currents, and energy although both waves and electrical currents involve the movement of energy, they are distinct phenomena that occur in different mediums and generate electricity in different ways.
What is the significance of the ocean waves?Ocean waves are caused when the wind blows or passes over the surface of the water, which leads to the generation of larger waves and these waves transfer energy through the ocean's water, which can be used to generate electricity using wave energy converters. They are caused by a variety of factors, including differences in water temperature and salinity, the rotation of the earth, and winds etc.
Hence, ocean waves, currents, and energy although both waves and electrical currents involve the movement of energy, they are distinct phenomena that occur in different mediums and generate electricity in different ways.

3. How can diversity within an ecosystem be compromised?
O by regulating human activity within an ecosystem
O by helping to maintain habitats that have been disturbed
O by building structures on natural habitat areas
O by leaving the ecosystem alone to fend for itself
Answer:
O by building structures on natural habitat areas
Explanation:
The diversity within an ecosystem can be compromised by building structures on natural habitat areas.
An ecosystem is part of the environment made up of living and non-living components in their natural habitats.
Diversity entails variations in the life forms within a particular ecosystem. When human-induced pressure begins to impact the environment, diversity is threatened Nature has its balancing effect the allow for a wide range of organisms to thrive. When human builds structures, part of the natural habitat is lost.Answer:
building structures on natural habitat areas

Most plant leaves contain yellow and orange carotenoids as well as green chlorophylls. Why then are most leaves greenish
Answer:
Because the leaves contain a greater concentration of green chlorophylls than yellow and orange carotenoids.
Explanation:
Chlorophyll and carotenoids are both pigments found in the cells of organisms like plants. They have differing color range depending on which wavelength of light they absorb and which they reflect. For example, chlorophyll pigment are green because they reflect green light and absorb others.
According to this question, the leaves of most plants contain yellow and orange carotenoids in addition to green chlorophylls but leaves are mostly green. This is because there is an abundant of chlorophyll pigment than any other pigment in the leaves of most plants. Hence, GREEN COLOR conferred by chlorophyll dominates and masks the color appearance of the other accessory pigments like yellow and orange carotenoids.
When the plant cell is swallowed by water without exploding it is in what case
Answer:
It is in hypotonic case.
Explanation:
The plant cell is in hypotonic case because the the solute concentration outside the cell is lower than in the cell. Plant cell do not burst in hypotonic solution because they have a cellulose cell wall outside its cell membrane. The cell wall is permeable and it's prevent the cell from bursting after it absorb water through osmosis.
One function of the vacuole is the storage of water.
Name, in sequence, the three parts of a cell that water must pass
through to reach the vacuole.
[2]
Answer:
cell wall ⇒ plasma membrane ⇒ cytoplasm
Explanation:
Water enters the plant through several pathways. If the "Vacuolar Pathway" will be followed, the water will enter the plant through the cell wall, going to the plasma membrane, then to the cytoplasm and then into the "vacuole." The cell wall functions to protect the plant's cell membrane/plasma membrane. The plasma membrane is semipermeable and it allows materials to be transported in and out of the cell. The cytoplasm consists of the plant cell's organelles. One of its organelles is the "vacuole," which is responsible for the plant's homeostasis.

Primary Consumer means organisms that primarily eat plants and have low energy levels. Squirrels fit into that category. They're almost always herbivores.
Secondary Consumers eat both plants and animals in the Primary Consumer. Crows are technically secondary consumers but I've never seen one eat a squirrel before.
Tertiary Consumers are predators that have the highest energy levels and are at the top of the food chain. Coyotes eat both squirrels and crows.
