What is the self-feeders for Paramecia?
Write your response below
Answer:
Paramecium (also Paramoecium, is a genus of unicellular ciliates, commonly studied as a representative of the ciliate group. Paramecia are widespread in freshwater, brackish, and marine environments and are often very abundant in stagnant basins and ponds. Because some species are readily cultivated and easily induced to conjugate and divide, it has been widely used in classrooms and laboratories to study biological processes. Its usefulness as a model organism has caused one ciliate researcher to characterize it as the "white rat" of the phylum Ciliophora.

Answer:1. Saturated zone
2. the water table
3. Aquifer
4. Land subsidence
Explanation:The saturated zone beneath the water
An aquifer is defined as a body of rock or unconsolidated sediment that has sufficient permeability to allow water to flow through it.
Land subsidence occurs when there is a loss of support below ground. This is most often caused by human activities, mainly from the overuse of groundwater, when the soil collapses, compacts, and drops.

C- Car A is moving faster than Car B.
E- Car A and Car B pass each other at the crossover point on the graph.
The statements best describe the motion of Car A and Car B are Car A and Car B are moving in opposite directions, Car A is moving faster than Car B, Car A and Car B pass each other at the crossover point on the graph. Therefore, option B, C and E are correct.
What do you mean by motion of car ?Periodic motion is a type of motion in which the body follows the same path over and over again. In the preceding question, we are told that vehicles travel on a straight road. So, the motion it performs is rectilinear.
The frictional force between the road and the tire causes the tire to "push" off the road, propelling the car forward.
Motion is defined as a change in position over time or with respect to a fixed point. If we are sitting in a moving car, we are moving to someone outside the car.
Thus, option B, C and E are correct.

The formula for calculating density, D, is D=M/V, where M represents mass and V represents volume.
For liquids, volume is often given in cubic centimeters (cc), which is the same as cm 3. If the density of an unknown liquid is 1.6 g/cc, what is the mass of 800 cc of the unknown liquid in grams (g)?
0.002 g
1.6 g
500 g
1280 g
Answer:
The answer is; D
Explanation:
Density 1.6g/cc means that every 1(one) cubic centimeter of the liquid has a mass of 1.6 grams.
Then, what about 800 cubic centimeters – how much mass, in grams, will it have ?
= 1.6 * 800 = 1280 g

How many Hydrogen atoms are present in this chemical equation: 3HCl
Answer:
pls mark as brainliest!!!!!!
Explanation:
If you considering in smaller scale You can simply say that “There is One Hydrogen atom Binds with Cl atom”. But when we are using this chemicals in Labs.
We talking in Moles
Mole is a quantity defining unit. Which is larger than you couldn't Imagine. 1 mole of pebbles can covered whole surface of earth.
1Mole=6.022×1023
It means 1 mole of Hydrogen is containing 6.022×1023 atoms. Be aware “Be aware thats a Quantity defining factor” Then we can get actual ratio of chemical formula..
HCL “The chemical formula”
H : 1 “Above chemical formula containing 1 atom to binds with another species”
Cl : 1 “Clorin also same as Hydrogen”
Then, You can multiply Ratio of atom by Avagadro Constant which is we pre defined as 1 Mole.
For understand it simply This statement would be helpful.
1 mole containing, Avagadro number of atoms
Hope This would be helpful!
Answer:
the answer is going to be 3 because it asked how many atoms of hydrogen it never said how many number of atoms of hydrogen.
so,
HCl has 1 atom of hydrogen in ONE MOLE but there are 3 moles given so you multiply the atoms of hydrogen by 3 that is going to be your answer i.e. 3
Which best explains why metal cooking utensils often have a plastic coating on their handles? Plastic melts less easily and lasts longer than metal. Plastic reduces the transfer of thermal energy to hands holding the utensils. Plastic molds more easily into shapes like long, thin handles. Plastic increases the rate of conduction from the utensil to the food.
answer quickly, please
Metal cooking utensils often have a plastic coating on their handles because it reduces the transfer of thermal energy to the hands holding the utensils. Therefore, option (B) is correct.
What is thermal energy?Thermal energy can be produced in a substance when an increase in temperature causes atoms to move at a higher speed and result they collide with each other. The energy generated from the temperature of the heated material is called thermal energy.
Thermal Energy is due to the random motion of molecules in a system and is directly proportional to the temperature. The greater the temperature the greater the movement of molecules and the greater the thermal energy of the system.
The thermal conductivity of metal does show a variation with an increase in temperature. As metal utensils have high conductivity for thermal energy therefore plastic handles are used to prevent the transfer the thermal energy.

At which type of boundary do lithospheric plates collide?
This is Earth science
Answer:
convergent boundary
Explanation:
A convergent boundary is an area on Earth where two or more lithospheric plates collide. One plate eventually slides beneath the other causing a process known as subduction. The subduction zone can be defined by a plane where many earthquakes occur, called the Wadati–Benioff zone.
