Many small freshwater organisms have a structure called a contractile vacuole, which pumps water out their body. Explain how this process is an example of active transport.
Answer:
1: The process of osmosis would cause water to move into the cells causing them to swell and possibly burst. Many freshwater one celled organisms have structures called contractile vacuoles. These structures collect and pump out excess water that accumulates in the cell.
2: During active transport, a protein pump uses energy, in the form of ATP, to move molecules from an area of low concentration to an area of high concentration. An example of active transport is the sodium-potassium pump, which moves sodium ions to the outside of the cell and potassium ions to the inside of the cell.

The nucleus has a system of _____ embedded within its outer membrane which allows communication between the nucleus interior and the cytoplasm.
Answer:
pores
Explanation:
The nucleus consists of "nuclear pores" on its outer membrane. Each of these are surrounded by nuclear pore complex. It allows the pore to regulate the movement of molecules between the nucleus and the cytoplasm. It allows small particles to pass through such as ribosomal proteins. It prevents most large particles (except for histone) from passing through; thus, it is selective in nature. This function of the pores clearly shows that it allows communication to occur between the nucleus interior and the cytoplasm.

The main function of the human digestive system is to A. rid the body of cellular waste materials B. process organic molecules so they can enter cells C. break down glucose in order to release energy D. change amino acids into proteins and carbohydrates
Answer:
Hi there your answer is B
Explanation:
There are a lot of functions to the digestive system like absorbing nutrients, get rid of waste but the main function is to process organic molecules so they can enter cells.
Hope this helped :)
Human Digestive System is a complex system made up of organs, tissues, and hormones. The primary function of the human digestive system is to break down and process food into nutrient molecules.
The correct answer is:
Option B. process organic molecules so they can enter cells
The functions of the human digestive system are:
The digestive system uses a chemical or mechanical process to break down the complex food substances into nutrient molecules. These molecules are then absorbed by the cells. The digestive system is involved in the assimilation and absorption of the nutrient molecules to yield energy.Thus, the digestive system process the food and break it down into simpler forms, so it can be absorbed by the cells.

Are catabolic pathways endergonic or exergonic reactions? Compare the amount of free energy in the reactants to the amount of free energy in the products of a catabolic pathway.
Answer:
Catabolic reactions are exergonic.
Explanation:
Exothermic reactions are catabolic, that is, they catalyze molecules, disintegrate them to be able to release energy to the environment that surrounds them and that is how they release or yield to the environment.

Make a list of three
other scientific words that have
-tion as a suffix.
Answer:
Condensation
Evaporation
Dissection
Reproduction
Explanation:
I gave an extra so you had a couple of options!
There are many more words with the suffix "tion," such as evolution, reproduction, and regeneration, and here the evolution is possible through sexual reproduction, and the regeneration is a process in which new cells are grown.
What is the significance of reproduction in living things?In the living forms, both types of reproduction are seen, such as sexual reproduction and asexual reproduction, and in the case of sexual reproduction, there is variation among the offspring due to the crossing over and the recombination, whereas this is not seen in the case of asexual reproduction. Asexual reproduction is seen in plants and others, while the parents and offspring are similar.
Hence, there are many more words with the suffix "tion," such as evolution, reproduction, and regeneration, and here the evolution is possible through sexual reproduction, and the regeneration is a process in which new cells are grown.

summarize the process of the water cycle.
Answer:
Earth's water is always in movement, and the natural water cycle, also known as the hydrologic cycle, describes the continuous movement of water on, above, and below the surface of the Earth. The hydrologic cycle begins with the evaporation of water from the surface of the ocean. As moist air is lifted, it cools and water vapor condenses to form clouds. Moisture is transported around the globe until it returns to the surface as precipitation. Groundwater either seeps its way to into the oceans, rivers, and streams, or is released back into the atmosphere through transpiration. The balance of water that remains on the earth's surface is runoff, which empties into lakes, rivers and streams and is carried back to the oceans, where the cycle begins again.

A frameshift mutation will change a.Only one codon b.Only two codons c.All codons both before and after the point at which the mutation occuredd.All codons only after the point at which the mutation occured
Answer: d. All codons only after the point at which the mutation occurred.
Explanation:
Mutation can be defined as the change that occurs at the genetic level.
A frameshift mutation can be defined as the genetic mutation in which the deletion or insertion of the number of the nucleotide in the sequence of DNA results.
The frameshift mutation changes the reading frame of the group of codon from the point where the change has occurred.
This results in the completely different translation from the previous sequence.

When the diaphragm contracts, the size of the thoracic cavity ________, the pressure inside the thoracic cavity ________, and air flows ________ the lungs. decreases; drops; out of decreases; rises; into increases; drops; into increases; drops; out of
Answer:
decreases; rises; out of
Explanation:
When the diaphragm contracts, the size of the thoracic cavity decreases, the pressure inside the thoracic cavity increases, and air flows out of the lungs.
During the process of breathing out, the diaphragm and the intercostal muscles relax and this leads to a decrease in the volume of the thoracic cavity. Since there is an inverse relationship between volume and pressure, the decrease in the volume of the thoracic cavity leads to an increase in its pressure. Consequently, the lung contracts and air is forced to leave it.
The diaphragm is a muscular structure, which is present below the lungs. The relaxation and contraction of the muscles help in the increasing and decreasing of the thoracic cavity during the breathing process.
The statement for the given blanks are:
When the diaphragm contracts, the size of the thoracic cavity increases, the pressure inside the thoracic cavity decreases, and airflow into the lungs.
The working of the diaphragm can be given as:
1. The diaphragm will contract during the inhalation process. The diaphragm will pull downward which will increase the size of the thoracic cavity and cause a decrease in pressure.
2. The change in the pressure will result in the rushing of air inside the lungs, and will fill up the lungs.
Thus, the contracting and relaxing of the diaphragm will result in the breathing process.
