Mr. Chavez wants his class to prepare a procedure that would demonstrate cellular diffusion. Which of the following procedures would best demonstrate cellular osmosis?
A. A procedure that uses the skins of potato left overnight in oil
B. A procedure that uses a cluster of grapes left overnight in a high concentration of salt water
C. A procedure that uses a 2-liter bottle filled with oil and water and left overnight
D.A procedure that uses a banana that has been left overnight in milk
Answer:
B
Explanation:
The second option correctly shows the process of cellular osmosis.
When the grapes would be immersed in water, the molecules of water move across the cell membrane from the region of low to high solute concentration. Due to this, the water would leave the cells and diffusion of water from the cells of the grapes. Thus, option B is the correct answer.
In conclusion, the procedure that uses a cluster of grapes left overnight in a high concentration of salt water would BEST demonstrate cellular osmosis (Option B).
Osmosis refers to the movement of a solution (often water) across a selectively permeable membrane.This movement (osmosis) is due to the difference in solute concentrations on both sides of the semipermeable membrane.In osmosis, water molecules move from a region of low concentration of solutes (e.g., salt) to a region of high concentration of solutes.
In conclusion, the procedure that uses a cluster of grapes left overnight in a high concentration of salt water would BEST demonstrate cellular osmosis (Option B).

C. True in all elements, it maintains its properties even after it combines with
other elements.
D. True to all elements, they have the properties after they are combined.
The correct option is D.
True to all elements, they have the properties after they are combined.
Explanation:
Elements are pure substances which can not be divide by any form of chemical means.
True to all elements, they have the properties after they are ccombine because elements contain atoms and atoms is the smallest indivisible units which retain chemical properties because chemical bonds are formed between the atoms of elements.

Explanation:
The level of organization from lower to higher are atoms, molecules, organelles, cells, tissues, organs, organ systems, organisms, populations, communities, ecosystems, biomes and biosphere.
What is ecosystem ?An ecosystem is the unit of ecology, a structural and functional unit of where the living organisms dwell with each other and with their surrounding environment and the term was coined by A.G.Tansley, an English botanist, in 1935.
The structure of an ecosystem can be up two types such as Biotic Components and Abiotic Components, both the components are interrelated where the flow energy and components occur throughout the boundaries.
Biotic components belongs to all living components which can be classified into autotrophs, heterotrophs and saprotrophs. Autotrophs are the producers like plants which make food independently by photosynthesis.
The organisms that depend on other organisms for their food called as consumers or heterotrophs, it can be classified into primary consumers, secondary consumers and tertiary consumers.
Primary consumers are herbivores, Secondary consumers get energy from primary consumers can be either carnivores or omnivores. Tertiary consumers get energy from on secondary consumers.
Quaternary consumers prey on tertiary consumers, Decomposers include saprophytes such as fungi and bacteria depend on dead and decaying matter.

Mrs. Gupta is the Cub Scout den mother. She is taking a troop of boys on a camp out and believes it will be easier if she schedules the outing to happen during the full moon. Last night she observed a third quarter moon. Approximately how many days will she have to wait before the full moon? 7 14 21 28
Answer:
The correct option is 21
Explanation:
First of all, it should be noted that the full moon is usually observed in the middle of the lunar month, which is usually 29 or 30 days, hence the full moon can be observed either on the 13th but most likely on the 14th and/or the 15th of the lunar month.
At the early days of the month, the new moon begins to form a crescent which appears and continues to get fuller (called waxing crescent) as the day goes by until half of the moon is noticed (usually after about seven days) on one side, this is known as the first quarter.
After half of the moon is noticed on one side, the moon continues to get fuller (called gibbous moon) until a full moon is noticed on the 14th/15th day. This full moon then starts waning or becoming smaller until the other half of the moon becomes visible while the initially seen half becomes invisible/clouded (this is called third quarter). This happens after another 7 days or on the 21st day. This half moon continues to get smaller (forming a waning crescent) until no moon is seen at the end of the month (around the 28 or 29th day) which is referred to the new moon.
Hence, we can see from the above that from the third quarter to a new full moon will go through the steps below
third quarter ⇒ new moon ⇒ first quarter ⇒ full moon
If each step takes about 7 days and there are 3 steps, the approximate number of days she has to wait before the full moon is 21 days.
What best explains how you can smell burned toast from another room?
where is sugar removed and how can you tell
Explanation:
What you need to understand first, is the digestive system, after that, you'll probably be able to understand not only sugar, but other components of your food too.
It all starts at your mouth, you are going to do a lot of the job for the food to get to your stomach by chewing it. After it gets to your stomach, the digestion will do its job as the pH there is less than 7. After this process, the food is going to your intestine, and then, it's right here, that the sugar/carbohydrates you ate are going to get into your blood. After this, sugar is going to be used to create energy for your cells and body to work properly, with that, sugar is consumed and you can start the process all over again.

In an investigation to determine a factor that affects the growth of rats, a student exposed 100 rats of the same age and species to identical conditions, except for the amount of living space and the amount of food each rat received. Each day the student measured and recorded the weight of each rat. State one major error that the student made in performing this
Answer:
Violating 'Ceteris Paribus' {Other factors constant} assumption, as both food & space are varied (simultaneously)
Explanation:
Weight Growth is the dependent (effected) variable in this case. And, independent (causal) variables are food amount are living space respectively.
However particular independent factor's (food or living space) impact on dependent variable ie weight growth : can be determined only by - examining individual variable (food or living space) impact on weight growth. So, either of the two variables should be varied, & not both should be varied simultaneously.
This would imply depiction of each factor's clearer individual impact on the dependent factor.
