Essentially, when you breathe in the lung take in oxygen and pass it along to the bloodstream, which brings it to your bodies cells. In return it picks up carbon dioxide, which the lungs dispose of. Every time you breathe this process is happening. That is why it's crucial to keep your lungs healthy.
Carbohydrates, proteins, and lipids are important molecules that make up the structure of the cell membrane. They help move materials into and out of the cell through the cell membrane
In what way is the cell membrane like a security guard?
Answer:
The cell membrane only alows certian materials to move through the membrane. Just like a security guard the membrane sorts through the good stuff and lets it past, but if someone or something bad comes along the security guard stops it. Just like the cell membrane.

What happens to the matter and energy in fruits as they decompose.
Please help! I really need help in science and no one in my family can help me! I will ask more science questions after this just in case you can help with those too
Answer:
During the process of decomposition, the decomposers provide food for themselves by extracting chemicals from the dead bodies or organic wastes; using these to produce energy. The decomposers will then produce waste of their own. In turn, this will also decompose, eventually returning nutrients to the soil.

What is the function of an animal cell I really need help!
Answer: They are eukaryotic cells, meaning that they have a true nucleus and specialized structures called organelles that carry out different functions. Animal cells do not have plant-specific organelles like cell walls, which support the plant cell, or chloroplasts, the organelle that carries out photosynthesis.

1. What is the role of a receptor in helping an
organism maintain homeostasis?
A. receives messages sent by the control center
B. carries out a response to restore internal
conditions
C. detects stimuli and sends information to the
control center
D. compares current conditions with ideal values
for those conditions
Answer:
b
Explanation:
Homeostasis has been the tendency of the organism to maintain the equilibrium state. The stimuli are detected and transmitted to the control center by the receptors. Thus, option C is correct.
What is homeostasis?Homeostasis is the physiological process that monitors the internal environment of the body. This involves the feedback system that includes receptors that report and transfers the information to the control center of the body.
The receptor is involved in detecting the stimuli in order to generate the response through the feedback control system. The mechanism involves the effector that provides a response to the stimuli detected and transmitted by the receptors.
Therefore, in option C. the receptor sends information by detecting the stimuli.

Answer:
This type of natural selection occurs when there are selective pressures working against two extremes of a trait and therefore the intermediate or “middle” trait is selected for. If we look at a distribution of traits in the population, it is noticeable that a standard distribution is followed: Example: For a plant, the plants that are very tall are exposed to more wind and are at risk of being blown over. The plants that are very short fail to get enough sunlight to prosper. Therefore, the plants that are a middle height between the two get both enough sunlight and protection from the wind.
This type of natural selection occurs when selective pressures are working in favour of one extreme of a trait. Therefore when looking at a distribution of traits in a population, a graph tends to lean more to one side: Example: Giraffes with the longest necks are able to reach more leaves to each. Selective pressures will work in the advantage of the longer neck giraffes and therefore the distribution of the trait within the population will shift towards the longer neck trait.
This type of natural selection occurs when selective pressures are working in favour of the two extremes and against the intermediate trait. This type of selection is not as common. When looking at a trait distribution, there are two higher peaks on both ends with a minimum in the middle as such: Example: An area that has black, white and grey bunnies contains both black and white rocks. Both the traits for white and black will be favored by natural selection since they both prove useful for camouflage. The intermediate trait of grey does not prove as useful and therefore selective pressures act against the trait.
Genes help to define who an individual is inside and out. In addition to visible traits like weight and eye color, psychological qualities such as personality traits, intelligence, risk of mental illness, and more have been linked to genetics.

The earth rotates on its axis in a counterclockwise direction once every 24 hours, deflecting anything traveling long distances on or above the surface. This is known a the Coriolis Effect. What impact could the Coriolis Effect have on weather patterns
Answer:
in the Southern Hemisphere, currents are deflected to the left. As a result, storm systems seem to rotate clockwise. Outside storm systems, the impact of the Coriolis effect helps define regular wind patterns around the globe. As warm air rises near the Equator, for instance, it flows toward the poles.

Answer:
B. The first generation will not have short plants. The short trait will return in the second generation.
Explanation:
If T is for Tall and t is for short, then the first generation doesn't have any short offspring. We can rule out answer choices A and D.
The second generation results in TT, Tt, Tt, tt.
TT is a tall Offspring.
Tt is a Tall Offspring, with a small t as a recessive trait.
tt is a short offspring because both the recessive traits (t) are together.
We can rule out option C.
That leaves us with the correct answer being B. The first generation will not have short offspring, but will pass it on to the second generation, which will have a short offspring (25% chance of having short offspring).
Ivan reads a story about a population of mice that become stranded in a dark jungle. Some mice are dark brown, while others are white. According to the process of natural selection, predict which mice would be more successful living in a dark jungle. Explain natural selection and your prediction.
Answer:
The dark brown mice would be more successful in a dark jungle since the darker color of their fur would make it hard for predators to spot them.
The process of natural selection, predict which mice would be more successful living in a dark jungle is de dark brown.
What is natural selection?Natural selection is one of the main mechanisms of evolution. In a very simple way, we can say that natural selection is a process in which the fittest organisms are selected, survive in the environment, reproduce and pass their characteristics on to their descendants.
In this case, as it is a very dark forest, an animal with a white coat will attract more attention while an animal with a dark brown color will only be camouflaged in the environment.

Which of the following is not a key ingredient in cloud formation?
particles. drizzle. water vaper. drop in air pressure
Answer:Drizzle
Explanation:
Clouds require water vapor, particles the vapor can condense around, and a drop in air pressure to form.
Cloud formation is a process that begins with a drop in air pressure. An ingredient that is not key in the formation of clouds is;
A. DrizzleDrizzle is not an important factor in the formation of clouds. Clouds are formed when water and ice are suspended in the air.
The process of cloud formation begins when the terrain is heated up by the sun.
Wind blows more around the areas of low pressure thus causing the rising of warm air which holds up water.
After some time, this air becomes condensed and falls down as rain.
Summarily, Drizzling is not an important part of cloud formation.

A reproductive cell that is resistant to harsh conditions and capable of developing into an adult without fusing with another cell prokaryote D. A single-celled organism that lacks a nucleus and membrane-bound organelles
Answer:
Statement A - cellular membrane
Statement B - eukaryote
Statement C - spore
Statement D - prokaryote
Explanation:
The cell membrane is a protective layer present around the cell and cell organelle that regulates and allows different molecules to enter and exit to regulate homeostasis.
Eukaryotes are the organism that can be unicellular or multicellular with the cells contain a nucleus in it.
Spores are reproductive cells that has a resistant layer that protects the cell from an unfavorable condition and capable to form an adult.
An organism that is unicellular and lacks the nucleus is known as a prokaryote and bacteria is an example of such organisms.
