The graph below shows the solute concentration inside a paramecium over time. What is happening at the time indicated by the pointer?
Water is moving rapidly into the paramecium by osmosis.
Water is moving rapidly out of the paramecium as the contractile vacuole contracts.
The paramecium is having a meal.
Solutes from the surrounding water are diffusing through the cell membrane, causing the solute concentration inside the paramecium to rise.
The pointer indicated the point at which water is moving rapidly out of the paramecium as the contractile vacuole contracts.
The pointer specifically indicates where the water solute concentration dropped. In order for the solute concentration of the water to drop, more water would have to be added.This means that water from the paramecium moves into the surrounding water as the contractile vacuole contracts. Consequently, the solute concentration of the surrounding solution decreases. When water moves from the solution into the paramecium, the solute concentration increases and this forms a continuous cycle in the graph.More on water movement by osmosis can be found here: https://brainly.com/question/21395644?referrer=searchResults

Explanation:
Break down the following equations into two half equations(One for oxidation, one or reduction )
1. Cu + 2Ag+ ➡️Cu2+ +2Ag
2. Cl2 +2I- ➡️I2 + 2Cl-
in reaction "1", the copper is being oxidized from 0 to +2 by losing 2 electrons
Cu---->Cu2+ + 2e-in reaction "2
in reaction "1" the silver is being reduced by gaining those 2 e-.
2Ag1+ + 2e----------->2Ag
In reaction "2", the iodine is being oxidized by losing 2 e-
2I- -------------> I2 + 2e
In reaction "2" the chlorine is being reduced by gaining those 2 e
Cl2 + 2e------------> 2Cl-
To solve such this we must know the concept of redox reaction. Therefore, the half reaction for the given reactions can be written as
1. Cu + 2Ag⁺ [tex]\rightarrow[/tex]Cu²⁺ +2A

Answer:
please mark as brainliest
Explanation:
Any substance that inhibits the growth and replication of a bacterium or kills it outright can be called an antibiotic. Antibiotics are a type of antimicrobial designed to target bacterial infections within (or on) the body. This makes antibiotics subtly different from the other main kinds of antimicrobials widely used today:
Antiseptics are used to sterilise surfaces of living tissue when the risk of infection is high, such as during surgery.
Disinfectants are non-selective antimicrobials, killing a wide range of micro-organisms including bacteria. They are used on non-living surfaces, for example in hospitals.
Of course, bacteria are not the only microbes that can be harmful to us. Fungi and viruses can also be a danger to humans, and they are targeted by antifungals and antivirals, respectively. Only substances that target bacteria are called antibiotics, while the name antimicrobial is an umbrella term for anything that inhibits or kills microbial cells including antibiotics, antifungals, antivirals and chemicals such as antiseptics.
Most antibiotics used today are produced in laboratories, but they are often based on compounds scientists have found in nature. Some microbes, for example, produce substances specifically to kill other nearby bacteria in order to gain an advantage when competing for food, water or other limited resources. However, some microbes only produce antibiotics in the laboratory
Answer:
Antibiotics commonly are produced by soil microorganisms and probably represent a means by which organisms in a complex environment, such as soil, control the growth of competing microorganisms. Microorganisms that produce antibiotics useful in preventing or treating disease include the bacteria and the fungi.

In covalent bonds, atoms share electrons, whereas in ionic bonds atoms transfer electrons. The reaction components of covalent bonds are electrically neutral, whereas for ionic bonds they are both charged.Covalent bonds are formed between two non-metals, whereas ionic bonds are formed between a metal and non-metal.
Answer:
Covalent bonds are defined as sharing of electrons, ionic bonds are the result of transferred electrons;
Covalent bonds form between non-metals (elements) and ionic bonds form between metal and non-metals (ions)
I WILL GIVE BRAINLIST!!!!!!!!!! HELPPPPPP (Learning Newtons Law) A 0.5 kg tennis ball, a 2 kg basketball, and a 5 kg bowling ball are all falling at the same speed.
Which has more momentum?
A: the 0.5 kg tennis ball
B: the 2 kg basketball
C: the 5 kg bowling ball
D: the all have the same momentum
Hurry!!! Only got a couple mins!!!
The momentum of the bowling ball will be greater than the rest balls.
The correct answer to the question is Option C. The 5 kg bowling ball
Momentum is defined as the product of mass and velocity i.e
Momentum = mass × velocity
If we keep the velocity of the object constant, the momentum will depend on the mass of the object.
Thus, the higher the mass, the greater the momentum and the lesser the mass, the smaller the momentum.
From the question given above,
Mass of tennis = 0.5 Kg
Mass of basketball = 2 Kg
Mass of bowling ball = 5 kg
We can see that the bowling ball has a higher mass.
Therefore, the momentum of the bowling ball will be greater than the rest balls.
The correct answer to the question is Option C. The 5 kg bowling ball

As a result the student collects 28.0 g of hydrogen and 224.0 g of oxygen. How many grams water did the student originally have involved in the experiment
The student originally has 252 grams of water in this experiment.
LAW OF CONSERVATION OF MASS:
The law of conservation of mass explains that matter (mass) can neither be created nor destroyed but can be changed from one form to another. This means that in a chemical reaction, the sum of the masses of the reactants must equate to the total mass of product(s). According to this question, a student conducts an experiment to separate water into hydrogen and oxygen. The student collects 28.0 g of hydrogen and 224.0 g of oxygen. Since hydrogen and oxygen are the constituent elements of water, the sum of their masses must equate the mass of water.
