Answer: Cell
Explanation: The cell is the most basic unit of life.
pH is an indicator of how acidic or basic a substance is. The pH scale ranges from 0 - 14, with 7 representing neutral. Acids have a pH below 7; bases, a pH greater than 7. Scientists determine the pH of a substance by using an indicator; indicators change color depending on the pH of a substance. Different indicators work at different pH ranges, as seen in the table above. The transition range of an indicator is the range of pH when the indicator changes from its low-pH color to its high-pH color. If the indicator shows a color between the two, then the pH lies somewhere in that transition range. You have been given a liquid that turns pink in phenolphthalein and blue in thymolphthalein. Tests with methyl violet and bromophenol blue resulted in a violet color. Based on your test results, determine which statements regarding the liquid are accurate. Choose ALL that apply.
A. The liquid is a base.
B. The liquid is an acid.
C. The liquid has a pH > than 7.
D. The liquid is an H⁺ donor.
E. The liquid mostly likely contains OH⁻.
The liquid is base. A base is a type of chemical that releases hydroxide (OH-) ions, receives protons, or donates electrons in an aqueous solution.
What are Bases?Bases have a few distinguishing characteristics that can be used to recognize them. They can taste harsh, react with acids to generate salts, have a tendency to be slick to the touch (like soap), and can catalyze some processes.
Arrhenius bases, Bronsted-Lowry bases, and Lewis bases are some examples of bases. The French scientist Louis Lémery coined the term "base" in 1717. Lémery used the term to refer to Paracelsus' alchemical notion of a "matrix" According to Paracelsus, natural salts form when a matrix and a universal acid interact.
Although Lémery may have coined the term "base" first, Guillaume-François Rouelle is generally recognized as the father of modern usage.
Therefore, The liquid is base. A base is a type of chemical that releases hydroxide (OH-) ions, receives protons, or donates electrons in an aqueous solution.

a 2 cm cube made of acrylic has a mass of 9.7 g. What is the density of the acrylic?
Answer:
here
volume of cube = l^3
=2cm^3
=8cm^3
now,
mass=(9.7÷1000)kg
=0.0097kg
volume=8cm^3÷100=0.08
we know that,
density=mass/volume
= (0.0097/0.08)kg/m^3
= 0.12125kg/m^3
Explanation:
the formula to calculate volume of cube is l^3 so here we find the volume of cube using this formula and then we convert gram into kilogram then convert cm into m then by applying the formula of density we find it density
A 2 cm cube made of acrylic has a mass of 9.7 g. The density of the acrylic is 0.12125 kg m3
What is density?Density is the mass of per unit volume.
[tex]Volume of cube = l^3\\=2cm^3\\=8cm^3[/tex]
mass 9.7 kg, converted into kilograms = 0.0097kg
[tex]Volume \;= \dfrac{8cm^3}{100} = 0.08[/tex]
Calculating the density
[tex]Density = \dfrac{mass}{volume} \\\\\dfrac{0.0097}{0.08} = 0.12125\;kg\;m^3[/tex]
Thus, the density of the acrylic is 0.12125 kg m^3.

How does the curved beak of a king penguin compare to the curved, cup-like structure of the pitcher plant?
They are both used to catch prey.
They are both used to collect water.
They both help avoid being eaten.
They both help protect the eggs.
please helpp
Both pitcher plant and king penguin use their physical adaptation to catch pray. The curved beak of the penguin helps them easily catch fish from snow similarly pitcher plant has the cup like structure to capture pray. Hence, option A is correct.
What is prey catching pitcher plant ?Pitfall traps, a prey-trapping mechanism with a deep hollow filled with digesting fluid, are modified leaves on a kind of carnivorous plants known as pitcher plants. Specialized leaves are used to create the traps in what are known as "genuine" pitcher plants. Using nectar, the plants draw in and suffocate their victim.
Flying, flying, or crawling insects that are out foraging are drawn to the hollow created by the cupped leaf by visual cues such nectar and anthocyanin colors.
Insects fall into the trap because the pitcher is slippery after being saturated by dew or nectar. To aid in preventing escape, the walls of the pitfall may be covered in waxy scales, protruding aldehyde crystals, cuticular folds, downward-pointing hairs, or lunate cells that originate from guard cells.
The sharp curved beak of penguin helps to easily catch their pray. Therefore, option A is correct.

How can a force act directly on an object? Explain.
Answer:
The quantity of force is expressed by the product of mass (m) and acceleration (a). Mathematically the equation can be written as
F = ma
Where,
F= Force
m = mass
a = acceleration
When a force acts on an object the objects the objects have different effects of force. So let us know about the effects of force on an object.
