Answer:
If a student breathes through a 3 feet long glass tube it will affect the physiology of the student in various ways such as a change in blood pH, urine pH, and rate of respiration.
It will result in an increase in the normal volume area of the trachea and bronchi as it is a closed system as a face mask. The increase in this dead volume are will result in double the volume of CO2. Decrease the pH of the blood.
When asked to breathe through 3-foot long glass tube there would reduced oxygen available to the tissue (hypoxia) which had the following effects discussed below.
Hypoxia occurs when there is reduced oxygen available to the body tissues.
When asked to breathe through a 3-foot long glass tube, it can lead to hypoxia.
The effect of hypoxia include the following:
Blood pH: Due to increase in anaerobic respiration in the tissues, lactate production increases leading to a fall in blood pH. Urine pH: Hypoxia leads to increase in renal sodium excretion which helps acid-base balance of the body fluid. Respiratory rate: There is significant increase in respiratory rate to compensate for the decreased tissue oxygen levels.Learn more here:

Since transport of materials in and out of the cell can only happen at the cell's surface, what happens as cells get larger? How does this impose a limit on cell size?
Answer:
The surface area/volume ratio will decrease
Explanation:
How does this impose a limit on cell size?
Because the ability of a cell to exchange substances with its environment is proportional to its surface area.
Hence, if surface area/volume decrease and get too small, surface area is not sufficient to take up substances needed to support metabolism or get rid of wastes.
describe the formation of tissues fluid and lymph
As fluid enters the tissue space from the blood stream pressure builds up in this space and as this hydrostatic pressure increases it causes the interstitial fluid to diffuse into the lymphatic capillaries once the interstitial fluid has entered the lymphatic capillaries it is called lymph
Answer:
Tissue fluid is formed because of the high hydrostatic pressure of the blood at the arteriole end of the capillary that pushes fluid out of the blood.These valves are large enough to allow proteins, which are too big to get into the capillaries, into the lymph vessels.
or
Tissue fluids is formed because of the high Hydrostatic pressure of the capillary that pushes fluids out of the blood. These valves are large enough to allow protiens, which are too big to get into the capillaries, into the lymph vessel.

Q: Predict and describe some possible effects to your entire food web if the following happened:
A mysterious virus has sickened the secondary consumer fish. There
are few survivors. Fortunately, this virus is not affecting organisms on any other trophic levels. However, the loss of these organisms is
affecting the rest of the food web. Please describe the possible effects:
Answer:
Less fish will disrupt the predators in the ocean. Sharks, and other predators in these oceans need a food source such as fish if this Virus does indeed kill these many fish. Meaning the virus is in this fish, It might spred to predators that eat these fish. Still if the predators of the food chain dont find these food sources for them i am sure they will die of starvation.
Explanation:
If a food source for animals is obsulete i am sure the predators of the animals will have starved to death like how, the Hot blob is affecting the Cassins auklet due to the Less amount of phytoplankton in the oceans.3. Analyze: From the observations you made above, can you state exactly why the aliens
changed their shape? Why or why not?
Answer:
They changed their shape.
Explanation:
The aliens changed their shape because their shapes makes the people frightened. Their shape structure is different from the humans so they change their shape in order to walk among people easily and interact with people which they can't do with their real body structure. So that's why they changed their shape when they interact with people or to walk among people.

How are rocks and air alike? A. People use them to build things. B. They are on the ocean floor. C. They are natural resources. D. People need them to live.
Answer:
i think its c
Explanation:
Answer: C.
Explanation: Natural resources are resources that exist without any actions of humankind. Basically materials or substances such as minerals, forests, water, and fertile land that occur in nature and can be used for economic gain. Rocks are a source of natural resources and so is air. If the answer is not correct, then it must be D.
If u know the water cycle please answer this question
Answer:
Gravity
Explanation:
Percolation is the process of a liquid slowly passing through a filter. It's how coffee is usually made. Percolation comes from the Latin word percolare, which means "to strain through." Percolation happens when liquid is strained through a filter, like when someone makes coffee.
Evaporation-the process of turning from liquid into vapor.
Condensation-water which collects as droplets on a cold surface when humid air is in contact with it.
and gravity- Gravity is the force of attraction between two objects, and Earth's gravity pulls matter downward, toward its center. It pulls precipitation down from clouds and pulls water downhill. The warm water near the surface of the ocean heats up with sunlight and evaporates, keeping the water cycle in motion.

B
Birds and Plants
С
Soil, Plants, and Birds
D
Water, Sunlight, Soil, and Air
Answer:
Water, Sunlight, Soil, and Air
Explanation:
Abiotic factors are the non-living components of an ecosystem. These are physical factors, such as water, sunlight, soil, and air.
In contrast, biotic factors are the living components and include birds and plants.
The way the biotic and abiotic factors interact with one another forms the ecosystem. The biotic factors rely on the abiotic factors to sustain their life.

Is the following sentence true or false? The apparent change in the
frequency and wavelength of a wave as it moves toward or away from an
observed is know as the Doppler effect.
True or False
Answer:
True
Explanation:
Doppler's effect is the apparent change in the wavelength and frequency of a wave as it moves towards or away from an observer.
The relative motion between the observer and the source causes changes to the wavelength and frequency. This effect is the doppler's effect. When a source moves closer, the frequency of the wave increases. For example, we see that effect of water ripples when a stone is dropped in still water.State two adaptations of the cell membrane

In cats, the allele that causes curled ears is dominant to the allele that causes normally shaped ears. If two hybrid curled-ear cats are mated, what percentage of the kittens is predicted to have curled ears?
Answer:
75% (3:4)
Explanation:
A hybrid organism is one that is heterozygous - it carries one curled allele and one normal allele.
Let's use the letter C. The curled allele is C, the normal allele is c.
The heterozygotes are therefore Cc.
The cross between the two cats is Cc x Cc.
C c
C CC Cc
c Cc cc
Organisms with the genotype CC and Cc are curled ears, since the C allele is dominant to the c allele.
1:4 of the genotypes are CC, and 1:2 are Cc, so 3:4 (75%) have the curled ear phenotype.

Answer:
Proteins made by free-floating ribosome's remain in that cell: whereas, proteins that travel through the endomembrane system leave by secretory vesicles.
Explanation:
A free-floating ribosome creates proteins within cells, but unlike normal ribosomes, this protein is left to float freely in the cell’s cytosol.
Furthermore, proteins that are synthesized in the rough endoplasmic reticulum will most likely be secreted into the extracellular environment.
I would like to apologize in advance if my answer was incorrect.
