how do molecules pass through the cell membrane
Answer:
The small molecules such as water and carbon dioxide can easily or directly pass through the membrane because they are neutral and so small. the movement of water through the membrane is referred to as osmosis. water can also pass through the membrane through channel protiens called aquaporins (AQP).

What type of research method would best answer the question “How many rivers in Florida have nitrate pollution in them?”
Answer:
Field study
Explanation:
I took the quiz and got it right. Hope this helps :)
The type of research method that would best answer the given question is field study. The correct option is C.
What is field study?Field studies are research activities that take place outside of your office or lab, in the context of the user.
There are numerous field-study methods and activities to choose from. Field studies also differ significantly in terms of how the researcher interacts (or does not interact) with participants.
Field research is a qualitative research method that involves observing and interacting with people in their natural settings in order to understand and interpret the social interactions of groups of people, communities, and society.
Field studies provide students with first-hand experiences that promote critical thinking, long-term retention, transferability, positive attitudes toward science, appreciation for nature, and increased scientific curiosity.
Field study is the type of research method that would best answer the given question "How many rivers in Florida have nitrate pollution in them?”
Thus, the correct option is C.

Explain how the electron transport chain makes ATP.
Answer:
t
Explanation:
While Glycolysis and the Citric Acid Cycle make the necessary precursors, the electron transport chain is where a majority of the ATP is created. The Electron Transport Chain makes energy ... At the end of the chain the electrons are taken up by oxygen molecules to make water. This is why oxygen is known as the final electron acceptor.
Answer:
Explanation:
during electron transport, energy is used to pump hydrogen ions across the mitochondrial inner membrane, from the matrix into the intermembrane space. A chemiosmotic gradient causes hydrogen ions to flow back across the mitochondrial membrane into the matrix through ATP synthase, producing ATP
What types of organisms have mitochondria
Answer:
sup ._.
Explanation:
The mitochondrion (/ˌmaɪtəˈkɒndrɪən/, plural mitochondria) is a semi autonomous double-membrane-bound organelle found in most eukaryotic organisms. Some cells in some multicellular organisms may, however, lack mitochondria (for example, mature mammalian red blood cells). A number of unicellular organisms, such as microsporidia, parabasalids, and diplomonads, have also reduced or transformed their mitochondria into other structures.

why does cell specialization occur in large multicellular organisms but not in small unicellular organisms? Thanks
Explanation:
Cell specialization is the differentiation of cells to perform very specific function. At the stage of cellular differentiation, the generic cells are transformed into very specialized cells.
Multicellular organisms have very complex body systems. They carry many different tasks. They have to move, find food, excrete, maintain balance within their body system and the environment etc.
To perform these tasks, cells must have specific functions because they would be in need of different materials to carryout the functions.A unicellular organism performs very simple functions of life. They do not require complex biological processes to manufacture their food and carry out life activities.
Cell specialization occurs in large multicellular organisms but not in small unicellular organisms because multicellular organisms have numerous cells but unicellular cells have only one cell.
CELL SPECIALIZATION:
Cell specialization is a phenomenon in living organisms in which different cells perform different and specific functions for the organism that contains them. Cell specialization strictly occurs in multicellular organisms i.e. organisms that possess more than one cell. This is because there are numerous cells to carry out specific tasks.On the other hand, in a unicellular organism i.e. organism that contain only one cell, cell specialization cannot occur. Therefore, cell specialization occurs in large multicellular organisms but not in small unicellular organisms because multicellular organisms have numerous cells but unicellular cells have only one cell.Learn more about cell specialization at: https://brainly.com/question/12683466?referrer=searchResults
sodium (NA) and water (H2O undergo a chemical reaction that produces sodium hydroxide (NaOH) and hydrogen gas (H2). Which equation represents this chemical reaction
Answer:
There are no options in this question, however, the equation can be provided. The answer is:
2Na + 2H2O --> 2NaOH + H2
Explanation:
This question is deacribing the equation between sodium (Na) and water (H2O) to produce sodium hydroxide (NaOH) and hydrogen gas (H2). The equation originally is as follows:
Na + H2O --> NaOH + H2
From the above equation, one would notice that it is not balanced because the number of atoms of each element is not the same on both sides of the equation. Hence, to balance the equation, a coefficient is used to make sure the same number of atoms of each element are on both sides.
We have;
2Na + 2H2O --> 2NaOH + H2

Answer:
A rock is a collection of minerals. In a cooling lava, mineral crystals do not have time to form and are very small. The chemical composition will be the same as if the magma cooled slowly. Existing rocks may be heated enough so that the molecules are released from their structure and can move around.
Explanation:
The unique shape that a mineral grows into is called its…
Answer:
Crystal form refers to the geometric shape of mineral crystals. Crystal form is caused by the symmetrical, three-dimensional arrangement of atoms inside the mineral.

Answer:
A. Mitochondria
Explanation:
Took the test
In your own words explain how the structure of the cell membrane determines what can and cannot pass through the cell membrane.
Answer:
The cell membrane is semi-permeable. (or selectively permeable). The unique structure of the cell membrane allows small substances (like oxygen or carbon dioxide) to easily pass through.
Explanation:
The principal components of the plasma membrane are lipids (phospholipids and cholesterol), proteins, and carbohydrate groups that are attached to some of the lipids and proteins. A phospholipid is a lipid made of glycerol, two fatty acid tails, and a phosphate-linked head group.
Answer:
Explanation:
Because the cell membrane is a selectively permeable membrane it decides what it will allow to pass through the membrane wall and what will not

What is the charge of the outside of the DNA molecule?
Answer:
It has an alternating chemical phosphate and sugar backbone, making the 'sides' of the ladder. (Deoxyribose is the name of the sugar found in the backbone of DNA.) In between the two sides of this sugar-phosphate backbone are four nitrogenous bases: adenine (A), thymine (T), cytosine (C), and guanine (G).
