specialized cells are found only in?
Answer:
Specialized cells are found only in multicellular organisms.
Explanation:
Or organisms are made up of more than one cell.
Specialized cells are generally found only in multicellular organisms.
What are multicellular organisms?A multicellular organism can be described as an organism that contains more than one cell, in contrast to a unicellular organism. Multicellularity has been independently at least 25 times in eukaryotes and in some prokaryotes, like myxobacteria, cyanobacteria, and actinomycetes.
All species of animals, plants, and most fungi are multicellular organisms, whereas a few organisms are partially uni- and partially multicellular, such as slime molds and social amoebae.
Multicellular organisms develop in many ways such as by cell division or by aggregation of many single cells. Colonial organisms can be defined as identical individuals joining together to form a colony.
Unicellular organisms are divided, and the daughter cells failed to separate which results in a conglomeration of identical cells in one organism, which could develop specialized tissues.

How can plants get the glucose monomers they need for building carbohydrate polymers?
Answer:
The sun is always how plants get glucose
The plants get the glucose monomers they need for building carbohydrate polymers by incorporating atoms from the surrounding environment.
What are carbohydrates ?The term carbohydrate is defined as an optically active polyhydroxy aldehydes or ketones or the compounds which produce units of such type on hydrolysis”.
Carbohydrates are made up of carbon, hydrogen, and oxygen. Monosaccharides, disaccharides, oligosaccharides, and polysaccharides are all types of carbohydrates.
Plants use atoms from their surroundings to incorporate the glucose monomers they require. In order to create glucose and oxygen molecules, plants use the carbon dioxide and water molecules in their surroundings.
Thus, The plants get the glucose monomers they require for building carbohydrate polymers by incorporating atoms from the surrounding environment.

Physical properties are used to classify and compare substances. Physical
properties can include density, thermal conductivity, electrical conductivity,
solubility, magnetism, melting point, and boiling point. Which statement is
correct about all of these physical properties?
They involve a change in the state of matter.
They involve the production of new substances.
They can be measured only after a change in state.
They are independent of the amount of the sample present.
Answer:
Physical properties involve a change in the state of matter.
Explanation:
A chemical change would change the chemical composition.
A physical change would change the state of matter, for example solid to liquid to gas are changes in state. So, this means when water changes states of matter it is a physical change.

In which of the following should chloroform be soluble?
silver iodide
silicon dibromide
dihydrogen monoxide
carbon tetrachloride
select all that applies
Answer:
carbon tetrachloride
Explanation:
In chemistry, it is common knowledge that like dissolves like. This means that nonpolar solutes dissolve in nonpolar solvents while polar solutes dissolve in polar solvents.
Chloroform is a nonpolar substance, we expect it to also dissolve in a nonpolar solution such as carbon tetrachloride.
Nonpolar substances possess the same kind of inter-molecular interaction between its molecules which enables the solute to effectively dissolve in the solvent.
The carbon tetrachloride should chloroform be soluble
The following should be considered:
In terms of chemistry, nonpolar solutes dissolve in nonpolar solvents while on the other hand, polar solutes dissolve in polar solvents.Since Chloroform is a nonpolar substance, we expect it to also dissolve in a nonpolar solution like carbon tetrachloride.Learn more: https://brainly.com/question/5763151?referrer=searchResults

explain what is random motion of particals
Answer:
Also known as Brownian motion
Explanation:
If you take a gas particle and drop it in a container, you will observe under a microscope the particle will be moving in a random pattern. Eventually it will collide with another particle. They are free to move. Each particle has it's own kinetic energy.
They can be described as small, discreet and meaning all the particles are separate. They will not stick together.
The path these particles take is random.
Example: Dust particles move randomly. The reason why the dust particles more randomly is because of the air or gas between them. You can observe dust particles in the air when you are looking in the sun light but you don't see the air molecules. It appears the dust is doing the moving but it's the gas in between them that is moving them.
Another example is : Pollen in water also moves randomly in water. Each water molecule is too small to see, but you can see the pollen moving because it is bigger. This is the Brownian motion.

Which of the following elements has the smallest
atomic radius?
O a. chlorine
O b. sulfur
O c. selenium
O d. bromine
Answer: It’s A. Chlorine
Explanation:
Chlorine has the smallest atomic radius among the given elements. Therefore, option A is correct.
What is the atomic radius?The atomic radius of an atom can be defined as the shortest distance between the center of the nucleus and the valence shell of the atom. An atomic radius can be described as half the separation between two atoms of the same element bonded together.
In general, the atomic radius reduces as we move from left to right in a particular period on the modern periodic table because while moving from left to right in a particular period, there is a rise in the effective nuclear charge. In periods, the new electrons enter the same electron shell.
The atomic radius increases when we move down a particular group because of the addition of a new principle shell.
Chlorine is present after the sulfur at the end of the same period. Therefore, Chlorine experiences a more effective nuclear charge than sodium so it has a smaller atomic radius.

A student made this mode using paper molecules and a piece of yarn. She want to shows how simple transport works. if the model starts as shown above, wha should the final model look like?
Answer:
I think the correct answer is B.
Explanation:
It was approved for me! Hope it helps.
According to the concept of diffusion, the final model would look like B as it has equal number of molecules on either side.
What is diffusion?Diffusion is defined as the process of movement of molecules which takes place under concentration gradient. It helps in movement of substances in and out from the cell.The molecules move from lower concentration region to a higher concentration region till the concentration becomes equal.
There are 2 main types of diffusion:
1) simple diffusion-process in which substances move through a semi-permeable membrane without the aid of transport proteins.
2) facilitated diffusion- It is a passive movement of molecules across cell membrane from higher concentration region to lower concentration.
There are 2 types of facilitated diffusion one is osmosis and dialysis.

Copper is known to have a density of 8.96g/cm3. If I have a 25 kg block of copper,
how much volume does it take up in cm3? In Liters?
Answer:
The answer is 2.79 LExplanation:
The volume of a substance when given the density and mass can be found by using the formula
[tex]volume = \frac{mass}{density} \\ [/tex]
mass = 25 kg = 25000 g
[tex]volume = \frac{2500}{8.96} \\ = 2790.17....[/tex]
= 2790 cm³
But 1000 cm³ = 1 L
2790 cm³ = 2.79 L
We have the final answer as
2.79 LHope this helps you

A car going from 10 miles per hour to 30 miles per hour. (A) Speed (B)Velocity (C)Acceleration
Answer:
It's C (acceleration)
Explanation:
Speed is how fast something is going. Velocity is something's speed AND direction (north, east, etc.) Acceleration is something increasing in speed. Since the car is going faster in this situation, it would be an example of acceleration.
