When placed in water, oil does not dissolve and stays separate. This means oil is_____ and ____.
Answer:
when placed in water, oil does not dissolve and stays separate. this means oil is immiscible and inorganic
Explanation:
When placed in water, oil does not dissolve and stays separate. This means oil is a non-polar and hydrophobic substance.
What are oils?Oils are organic compounds. They are nonpolar chemical substances that are made up of hydrocarbons. They're flammable, and they're extracted from vegetables plants, and animals.
Oils are not soluble in water because they are hydrophobic in nature, doubt a layer of oils is made of made up of a hydrophobic chain that is insoluble in water.
Substances are nonpolar substances are those substances which are insoluble in water. Oil is one of them. Polar substances are dissolved in water because they have hydrophilic ends.
Thus, oil does not dissolve in water and remains separate. Oil is a non-polar, hydrophobic substance, according to this.

What are sound waves
Answer:
Sound is a mechanical wave that results from the back and forth vibration of the particles of the medium through which the sound wave is moving. The motion of the particles is parallel (and anti-parallel) to the direction of the energy transport. This is what characterizes sound waves in air as longitudinal waves.
Answer:
Sounds waves are a type of energy that is manipulated by vibrant energy. Different variations of vibrant energy allows us to hear different sounds.

Why do globes lean sideways?
A.To allow them to spin easier
B.To demonstrate gravity
C.To demonstrate the passing of the seasons
D.To demonstrate the tilt of the Earth's axis
Answer:
D
Explanation:
Globes lean sideways To demonstrate the tilt of the Earth's axis. Option D is correct.
Globes lean sideways to demonstrate the tilt of the Earth's axis. The Earth is tilted on its axis by about 23.5 degrees. This tilt is what causes the changing seasons on Earth.
When a globe is tilted, it helps us visualize how different parts of the Earth receive different amounts of sunlight at different times of the year. For example, during the summer in the northern hemisphere, the North Pole is tilted towards the Sun, so it receives more direct sunlight and experiences warmer temperatures. At the same time, the South Pole is tilted away from the Sun, receiving less direct sunlight and experiencing winter.
By showing the tilt of the Earth's axis, globes help us understand why we have seasons and why they occur at different times in different parts of the world.
To summarize, globes lean sideways to demonstrate the tilt of the Earth's axis, which helps us understand the changing seasons on Earth. Option D is correct.

Explanation:
it is made of cellulose and its component is water loving or what we call hydrophilic thus it can transport large amount of substance into and within the cell
Answer: a-PROTEIN PUMP
Explanation:
Protein pump. – a kind of protein that is capable of pumping out compounds that could pose a threat to the cell. An example is AcrB, a bacterial protein complex that repels a wide range of antibiotics through its ability to capture and pump out a spectrum of structurally diverse compounds.
what is the Atomic Number of a neutral atom that has 5 neutrons and 4 electrons
The atomic number, z, is the number of protons. Assuming that this is an electrically neutral atom -the number of protons equals the number of electrons-, we can say that the atomic number is 4.
----------------------------------------
The representation of an element includes a superior number that indicates the massic number, and an inferior number that indicates the atomic number. We need to know that every atom is identified by its number of protons and neutrons. So,
Representation ⇒ ᵃ X ₀
Where
• X is the element
• a is representing the massic number, which is defined as the sum of the number of protons and the number of neutrons.
• z is the atomic number, which is the number of protons ⇒ represented as
0 above
In electrically neutral atoms, the number of protons equals the number of electrons. This means that the atomic number also indicates the number of electrons.
• We will call n to the number of neutrons, which equals a - z
When protons, neutrons, and electrons get together to form an atom, they lose part of their mass as energy. This is why the atomic weight is slightly inferior to the sum of masses.
So, what you need to know is that
• Nº of protons = Atomic number → z
• Nº of neutrons = Massic number - Atomic number → n = a - z
• Nº of Electrons = Nº of protons = Atomic number → z
Let us analyze the carbon example.
Element representation ⇒ ¹⁴ C ₆
• Massic number = 14
• Atomic number = 6
So, from this information we can assume that
• Nº of protons = Atomic number → 6
• Nº of neutrons = Massic number - Atomic number → 14 - 6 = 8
• Nº of Electrons = Nº of protons = Atomic number → 6
In the exposed example, we have an element, let us name it X with 5 netrons and 4 electrons. And we need to say what is the atomic number, z. In this example we do not need to do perform any calculations, because we already know that the atomic number = number of protons = number of electrons, so
• Nº of neutrons = Massic number - Atomic number → 5
• Nº of Electrons = Nº of protons = Atomic number → 4
from this information we can assume that the massic number is 9, because the massic number = number of protons + number of neutrons.

Thick Walled isodiametric dead cells
Answer:Sclerenchyma
Explanation:Sclerenchyma is thick walled dead lignified cells, they are hard and elastic. The sclerenchyma cells are divided into two groups namely fibers and sclereids. Sclerenchymatous fibers are branched/unbranched, long, hard, pointed cells with tapering ends, thick walls, and narrow lumen.
Answer:
Sclerenchyma is Greek word where "Sclero-" means hard and "enchyma" means infusion. This tissue consists of thick-walled, dead cells and protoplasm is negligible. These cells have hard and extremely thick secondary walls due to uniform distribution and high secretion of lignin and have a function of providing mechanical support
