Which structure pumps out excess water and wastes in a paramecium.
Answer:
Contractile vacuole
Explanation:
Contractile vacuole pumps out excess water and wastes in a paramecium.
The structure that pumps out excess water and waste in a paramecium is called the contractile vacuole. The contractile vacuole is a specialized organelle that collects excess water and waste materials from the cell and then contracts and pumps them out of the cell through a pore in the cell membrane.
What is water's role?Paramecium is a single-celled organism that belongs to a group of organisms called protists. Like other cells, a paramecium must maintain a proper balance of water and solutes inside its cell to function properly. However, because paramecia live in freshwater environments that have a lower solute concentration than the cell, water tends to move into the cell by osmosis. If too much water enters the cell, it can cause the cell to burst, so the paramecium has developed specialized structures to help regulate the movement of water.
Hence, the structure that pumps out excess water and waste in a paramecium is called the contractile vacuole. The contractile vacuole is a specialized organelle that collects excess water and waste materials from the cell and then contracts and pumps them out of the cell through a pore in the cell membrane.

Where would you find a strong acid on the pH scale?
A. 1
B. 5
C. 3
D. 13
Answer:
A. 1

A student conducted an experiment to test whether talking to plants would help them to grow faster. he set up the following two groups: group 1: spoken to and hand watered group 2: not spoken to and watered with sprinklers after three weeks, the plants in group 1 showed much more growth than those in group 2. based on the results of this experiment, which is the best conclusion? they are valid because the student ran a controlled experiment. they are not valid because the student did not control all the variables that can affect plant growth. they are valid because the dependent variable caused a change in the independent variable. they are not valid because the time frame to grow a plant is too short.
From the results in the experiment the best conclusion is : ( B ) they are not valid because the student did not control all the variables that can affect plant growth
Experimental varablesThe growth variables such as amount of light and amount of water need for the plants to grow effectively are not controlled in the experiment. The first group was hand watered while the second group was watered with a sprinkler therfore the amount of water reaching both groups are not the same therefore the experimental conclusion is not valid.

Explanation:
The average emission rates in the United States from burning coal are 13 lb/MWh (pounds per megawatt hour) of SO2 and 6 lb/MWh of NOx. (A pound is a unit of mass, and a megawatt hour is a unit of energy. ) Imagine that a scientist developed a new emission control device that can cut each of these emissions to 35% of the current output. If the device were installed, what would the average emission rates change to?
Answer:
The average emission of SO2 would be 4.55 lb/MWh, and the average emission of NOx would be 2.1 lb/MWh.
Explanation:
Answer:
With a NOx release speed of 2.1 lb/MWh, the run-of-the-mill SO2 spilling over rate would be 4.55 lb/MWh.

Photosynthesis takes place in Chloroplasts
In plants, the process photosynthesis occurs in chloroplasts which contain the chlorophyll. The chloroplast is seen on the mesophyll of the leaves. So in the given figure, chloroplast is present in the part 'E'. The correct option is E.
What is photosynthesis?The process by which the autotrophs convert light energy into chemical energy which is later used to perform the cellular activities is defined as the photosynthesis. The chemical energy is stored in the form of sugars, which are produced from water and carbon-dioxide.
Photosynthesis generally takes place in the specialized structure called the chloroplasts which consist of chlorophyll. It is the chlorophyll which absorb light energy from the sun. The majority of chloroplasts is present in the leaves which absorbs sunlight for the photosynthesis to occur.
So chloroplast is found in all green plants and algae. They are called the food producers of plants. This cell organelle is not found in animal cells.
Thus the correct option is E.

Calculate the sum of the decreases of the electric potential along the path, and the sum of the electric potential increases. State the relationship between the two
The sum of the decreases of the electric potential along the path will be 2.004V.
How to calculate the sum of the electric potential?From the complete information, the total current(I) is given as:
= 2/(4 + 3 + 5)
= 2/12
= 0.167A
V3 = I × 3
= 0.167 × 3
= 0.501V
V4 = I × 4
= 0.167 × 4
= 0.668V
V5 = I × 5
= 0.167 × 5
= 0.835V
Therefore, the sum of the decreases of the electric potential along the path will be:
= 0.501V + 0.668V + 0.835V
= 2.004V.

Describe how the malarial parasite affects a red blood cell in a person without the sickle-cell mutation (3-5 sentences):
Answer:
Invasion by the malaria parasite brings about extensive changes in the host red cells. These include loss of the normal discoid shape, increased rigidity of the membrane, elevated permeability to a wide variety of ionic and other species, and increased adhesiveness, most notably to endothelial surfaces. Now, sickle cells have membranes, stretched by their unusual shape, that become porous and leak nutrients that the parasites need to survive and the faulty cells eventually get eliminated quite fast by the organisms, destroying the parasite along the way.
