C)passive transport
Answer:
Diffusion is the spontaneous movement of gases, without the use of any energy or effort by the body, between the gas in the alveoli and the blood in the capillaries in the lungs.
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
Raising the temperature of a gas will increase its pressure if the volume of the gas
Answer:
raising the temperature of a gas will increase its pressure if the volume of the gas. and the number of particles are constant. the temperature and volume in a closed container of gas remain constant if the number of particles of gas is increased, the gas pressure will.
Which weather patterns are caused by atmospheric pressure differences?
Answer:
Low-pressure systems are associated with clouds and precipitation that minimize temperature changes throughout the day, whereas high-pressure systems normally associate with dry weather and mostly clear skies.
Explanation:
Storms, which are severe weather conditions, develop when air pressure differences speed up air flow.
What do you mean by atmospheric pressure differences ?It is the force that the air above a surface applies to it while gravity pulls the surface toward Earth. Weather is predicted by atmospheric pressure. There will often be clouds, wind, and precipitation when a low-pressure system enters a region. Fair, quiet weather is frequently a result of high pressure systems.
Air density variations, which are connected to temperature, are what are causing this shift in pressure. Because heated air's gas molecules move faster and further apart than cooler air's, warmer air is less dense than colder air.
Thus, various weather patterns are seen with change of atmospheric pressure.

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
Would you design cars with different masses or equal masses? Would you design your cars with high speeds or low speeds? Use Newton's Laws of motion to support your response.
Answer:
You can actually apply the same concept, obviusly you want the cars to be the same weight, and you want your cars to be not too fast, because of the same equation F=MA if the car is faster, is because it has higher acceleration, wich results in higher impact force.

Mimosa pudica is an example for ____
Answer:
Your answer is- Irritability
Irritability is the ability of an organism to respond to the external stimulus. The organism exhibit movement on receiving the stimulus from the internal or the external environment. The most common example of irritability is shown by the Mimosa plant which folds the leaflets when touched. The stimulus is passed on to the entire branch and then whole plant and all the leaflets close.
