What is the difference between osmosis and diffusion? A) osmosis only occurs in marine (salt water) organisms B) they are the same in all ways C) they are the same except osmosis specifically and only involves water D) diffusion only occurs in animal cells while osmosis occurs in all cells
Answer: The correct answer is: C The are the same except osmosis specifically and only involves water.
Explanation:
Osmosis is the process in which a solvent moves across a semipermeable membrane in order to dilute a concentrated solution and it ends up equalizing the concentration of the solution at both sides of the cell membrane.
On the other hand, diffusion occurs when particles move from an area of higher concentration to an area of lower concentration and it ends up equalizing the concentration.
So the main difference is the presence/ Lack of water in the processes.
In conclusion the correct answer is : C.
Kayla is reading the labels on a cereal box at breakfast. One label at the front of the box states that the cereal is a " good source of energy ". She turns to look at the nutrition label on the side of the box. The nutrition label shows the amount of different nutrients in grams per serving, In which should she expect to see the highest number of grams per serving ?
Carbohydrate.
Fat
Protein
Nucleic acid
Answer:
Taking into account that the food is "a good source of energy", Kayla would expect to see the highest number of grams per service in carbohydrates
Explanation:
Carbohydrates are molecules considered nutrients that represent the main source of energy for living beings. They are composed of carbon, hydrogen and oxygen, so they are also called carbohydrates.
Glucose, a simple sugar, is the most common energy substrate, capable of oxidizing to synthesize energy in the form of ATP, at the level of the mitochondria.
Carbohydrates can be found in cereals, and when it says on the label "good source of energy" it refers mainly to the high carbohydrate content of the food.
Other options do not apply because:
Proteins, constitute the structural and repairing element of the organism, in addition to the transport of biomolecules and regulatory function in the form of enzymes. Fat have a structural function and are the raw material for hormone synthesis, also playing a regulatory role. They provide reserve energy.Nucleic acids are not a source of energy since they are in charge of storing genetic information and protein synthesis.Where would the oxygen enter through in a food web?
Answer:
As with photosynthesis, plants get oxygen from the air through the stomata. Respiration takes place in the mitochondria of the cell in the presence of oxygen, which is called "aerobic respiration". In plants, there are two types of respiration: dark respiration and photo respiration

Both photosynthesis and cellular respiration are the results of change A) chemical B) physical C) both d) none
Answer:
I am thinking that the answer might be A. chemical
Explanation:
cellular respiration is a set of chemical reactions that cells use to change food,water, and oxygen into forms that is usable as energy for the cell. Photosynthesis is the process through which plants turn light energy into chemical energy.
the graph of the linear equetion 3x + 5y - 15 = 0 cuts the y - axis at the point full solution
Answer:
y = [tex]-\frac{3}{5}x+3[/tex]
Explanation:
3x + 5y - 15 = 0
So we want to get it in the form y = mx + b
Subtract 5y from both sides;
3x - 15 = -5y OR -5y = 3x - 15
Divide both sides by -5
y = [tex]-\frac{3}{5}x+3[/tex]
Why does quadrat sampling provide an accurate estimate of a population size within a defined area? Explain your reasoning.
Answer: it's better to do a small area at a time other than doing large areas where it will be hard to find specific species throughout the huge amount of land
A quadrat is a small, designated portion of the entire area to be sampled that is marked off so that the population within it can be counted by hand or by a similar method, like by taking an aerial photograph.
Quadrat sampling provide an accurate estimate of a population size within a defined area:
Quadrats allow researchers to study plant and animal populations spread out over large areas. They are inexpensive, relatively easy to design and adaptable for studying unevenly distributed populations.
Quadrats work well for observing changes to whole populations over time, including distribution patterns, nesting and overall health.
What is Quadrat Sampling?Quadrat sampling is a classic tool for the study of ecology, especially biodiversity. It is an important method by which organisms in a certain proportion (sample) of the habitat are counted directly.
It is used to estimate population abundance (number), density, frequency and distributions.
A quadrat is a small, designated portion of the entire area to be sampled that is marked off so that the population within it can be counted by hand or by a similar method, like by taking an aerial photograph.
Quadrat sampling methods are time-tested sampling techniques that are best suited for areas where access to a habitat is relatively easy.
Advantages:
- It sampling is easy to use and is inexpensive.
- It is suitable for studying plants, slow-moving animals and faster-moving animals with a small range.
- It requires the researcher to perform the work in the field and, without care.
- It measures abundance and needed cheap equipment.
Disadvantages:
- There exists biasness in favor of slow moving taxa.
- Collect only taxa that are present in the sampling time and not buried too deeper in sediment.
- It is a low estimate of taxonomic richness and assemblage composition.
- It is also a low detectability of among-site differences in assemblage composition.
- Some animals may experience harm if the scientist collects the population within the quadrat rather than studying it in the field.
Applications:
1. Quadrat sampling is broadly used in plant studies.
2. It is applied in ecology especially in biodiversity.
3. It is used to find the taxonomic richness of slow-moving taxa in a certain area.
4. It is the best measure of finding taxonomic richness in costal area.
5. It can be also used to evaluate the impact of weathering, trampling or erosion in an ecosystem or at a cliff or rock face.

Tides are caused by the suns and the moons gravity pulling water away from the planet. When the sun, moon and earth are at right angles, this is called a tide. When the sun, moon, and earth are parrallel to each other, this is called a tide. Word Bank: seasonal, diurnal, semidurnal, bore, period, rangeneapspring
Answer:
When the sun, moon and earth are at right angles, this is called a neap tide.
When the sun, moon, and earth are parrallel to each other, this is called a spring tide.
Explanation:
There are two types of tides spring tide and neap tide.
A spring tide occurs when the sun and moon are parallel to each other. This usually happens during periods of full and new moon, which are the moments that the moon can form a straight line with the sun, causing the gravitational force to interfere with the tide.
The neap tide, on the other hand, happens when the sun, moon and earth are at right angles. This moment occurs between the waxing and waning moons, where the sun and moon are at right angles and the earth is used as a vertex of that angle. In this type of tide the gravity of the sun becomes more influential than that of the moon.
Bats, birds, and humans are vertebrates. Birds and bats have wings that help them fly, and humans don't have wings. But if you looked at the bone structure of all three organisms, you'd notice similarities in the arrangement of their bones. What can you infer from this information?
Answer:
The correct answer is: Bats, birds, and humans share a common ancestor.
Explanation:
By observing the similarities between bats, birds and humans one can infer that according to the theory of evolution proposed by Charles Darwin, humans, bats and birds indeed share a common ancestor due to the similarities in the arrangement of their bones.
If bats, birds and human didn't share a common ancestor the arrangement of the bones would have been different.

An substance for a crystalline is NaCl
Answer:
The statements which are indicative of a covalent bond are as follows -:
Electron movement is concentrated somewhere between the two bonded nuclei.The greatest probability of finding the shared electrons is in the area of orbital overlap.The valence electrons involved in the bond are moving solely around the nucleus of the atom with the higher electron affinity.Explanation:
Among the given four statements, three statements are correct, the statement- "Electron density is focused on one element in the bond, generally resulting in the formation of a crystalline substance." is incorrect as In ionic bonds, crystalline formation takes place.
Somewhere between the two bonded nuclei, electron movement is centered. --: Covalent bonds are a class of chemical bonds in which valence electrons are shared between two atoms, typically two non-metals. The formation of a covalent bond helps the non-metals to obey the octet 's law and thus become more stable.The greatest probability of finding the shared electrons is in the area of orbital overlap.-: A pi bond (π bond) is a type of covalent bond arising from the overlap of two p orbitals side by side.The valence electrons involved in the bond are moving solely around the nucleus of the atom with the higher electron affinity.- : As pairs of electrons are exchanged by atoms, covalent bonding happens. In order to achieve further stability, which is gained by forming a complete electron shell, atoms can covalently bond with other atoms. Atoms can fill their outer electron shell and achieve stability by exchanging their outermost (valence) electrons.Hence , the correct option is D (I,II and IV )What 2 cats cannot compete for food against the python?

List three characteristics that bacteria have.
Answer:
1) Bacteria lacks of membrane-bound organelles
2) Bacteria is unicellular as well as a prokaryote cell
3) Bacteria doesn't have a nucleus
Hope this helps! :D
Bacteria have three distinct characteristics: plasmids, no nuclear membranes or membrane-bound organelles, and an extra cell wall surrounding the plasma membrane.
What are bacteria?Bacteria are prokaryotes by nature, and they lack a nuclear membrane. As a result, their genetic materials remain in the cytoplasm, and all the cellular activities take place in the cytoplasm. The bacteria have an extra plasmid that is mostly circular in nature, and due to this characteristic of the bacteria, they are used in recombinant DNA technology.
Because they lack an organelle, there is no Krebs cycle in them as seen in eukaryotic cells, which occurs in the mitochondrion for complete oxidation of glucose. Bacteria can grow at a faster rate than that of the eukaryotic cell, and this is one of the most advantageous things for them. cell wall makes them resistant to drought and other adverse climatic conditions.
Hence, the three distinct characteristics: plasmids, no nuclear membranes, and an intact cell wall.
