Answer:

0.24

2.7

1.3

Explanation:

Density equals mass divided by volume. the mass of the cork is 5.7 and its volume(the amount of water it displaced) is 23.5 so [tex]\frac{5.7}{23.5} = 0.24[/tex]

the mass of the granite block is 2700. the formula to get the volume of a rectangular prism is Volume = length × width × height so 20 × 5 × 10 = 1000

Density equals mass divided by volume so [tex]\frac{2700}{1000} = 2.7[/tex]

Density equals mass divided by volume.  the pipes mass is 78 and its volume is 60(amount of water displaced) so [tex]\frac{78}{60} = 1.3[/tex]

Answer:

Predators eat prey. When they do so, they are keeping the population or number of prey in check. Now, a lot of prey are either herbivores or omnivore, meaning plants are in their diet. If there were to be no predators, an absurd overpopulation of prey would arise. This would cripple the growth of young trees by the prey feeding on them, and overall would over-run their habitat, making the food sources scarce. When the food source gets so low they will die out or continue to move on to other surrounding areas and create the same problems.

Organelles serve specific functions to keep a cell alive.

Explanation:

Organelles are specialized structures that perform various jobs inside cells. The term literally means “little organs.” In the same way organs, such as the heart, liver, stomach, and kidneys, serve specific functions to keep an organism alive, organelles serve specific functions to keep a cell alive.

Biomes are large regions of the world with similar plants, animals, and other living things that are adapted to the climate and other conditions

Answer:

Biomes are large regions of the world with similar plants, animals, and other living things that are adapted to the climate and other conditions. An ecosystem is often much smaller than a biome, although the size varies. Ecosystems are the interactions between the living things and the nonliving things in a place.

Answer: c

Explanation: 3.0 is 1,000 times as many ions

The statement that best describes the difference is ; The substance with the lower pH has 1000 times as many hydrogen ions per volume of water. ( D )

Given that the substance have pH ; 3 and 6

To prove the statement above we will make use of the pH formula

pH =  -log(H⁺)

for substance with pH = 3

3 = - log(H⁺)

H⁺ ( hydrogen ions ) = 10⁻³

for substance with pH = 6

6 = - log(H⁺)

H⁺ ( hydrogen ions ) = 10⁻⁶

Hence we can state that the substance with the lower pH has 1000 times as many hydrogen ions per volume of water

Explanation:

The matching of each term with respect to its description is as follows:

An ecosystem may be defined as a place or an area where members of different species live together and interact with one another for the purpose of food, shelter, and space.

The Ecosystem comprises all biotic and abiotic factors of any geographical location. The Biosphere only includes the living forms where they efficiently live and play their roles. Habitat is the area where a particular type of organism is best adapted due to natural selection.

Therefore, the matching of each term with respect to its description is appropriately described above.

Explanation:

Examples of gymnosperms include cypress,pine, redwood, spruce and ginkgo.

Examples of angiosperms include apple, banana,peach, cherry and orange.

Also, angiosperms are seeds producing flowering plants whose seeds are enclosed within an ovary.

Gymnosperms are also seeds producing non flowering plants whose seeds are unenclosed.

B) Waxes, prevents water loss and repels water

Explanation:

Waxes, steroids, phospholipids, and triglycerides are types of lipids. All of them are made of Hydrocarbon chains that are hydrophobic.

Triglycerides (fats) - Storage molecules for the body's energy

Steroids - Sex hormones and cholesterol

Phospholipids - Cell membrane (Separates cytoplasm from the environment)

Therefore, Answer choice B) Waxes, prevents water loss, and repels water, is the only answer that correctly matches with the provided answers.

Answer:

Because each the cells would have different functions on different organisms.

Explanation:

Bacteria cells are usually prokaryotic which means that it is only composed of one cell. The single cell already has everything it needs so therefore, it isn't as complex as plant and animal cells.

Plants are autotrophs and produce their own food through photosynthesis. Plant cells would have a large vacuole, cell wall, chloroplasts, unlike animal cells.

Animal cells have all the cell organs that plant cells except a large vacuole, cell wall, and chloroplasts. Animal cells also have lysosomes in which plant cells don't.

The following formula is useful to determine the size of the cell ⇒ Size of the object = FOV / Fit number = dFOV / Fit number. If you have this data, you can estimate the size of the onion cell. According to the values we used, the estimated size of this onion cell is 112 μm.

-----------------------------------------------

Cells are too small to measure their sizes, so to know their actual size, we can make mathematical estimations to know their sizes, or we can use software programs. In this case, we are estimating their size using the following formula,

Size of the object = FOV / Fit number = dFOV / Fit number

To answer this question, we will replace the terms in the given formula.

→ First, we will get the FOV value. From references, we can assume that

You can also calculate the FOV by using a millimeter paper or rule.

Note: We will use these values to replace terms in the formula, but you can use the dFOV value calculated in question no. 3.

→ Second, we will count the number of cells that fit the field. We can see about four cells across the field of view.

→ Finally, we will replace the terms in the formula.

Size of the object = FOV / Fit number

Size of the object = 0.45 mm / 4

Size of the object = 0.112 mm

Since we generally use μm when referring to cell sizes, we need to multiply 0.112 x 1000 to get the size of the cell expressed in μm.

Size of the cell (μm) = 0.112 mm x 1000 = 112 μm
