Why do we exhale more carbon dioxide than we inhale?
Answers
Answer:
When we exhale, we breathe out less oxygen but more carbon dioxide than we inhale. The carbon we breathe out as carbon dioxide comes from the carbon in the food we eat. The carbon dioxide is dissolved in the blood, carried to the lungs by the circulation, and breathed out.
Answer:
because our bodies take in O and put out CO2
Explanation:
O is Oxygen
and CO2 is Carbon dioxide

Answers
Answer:
The correct answer is 4.ecosystem.
Explanation:
An ecosystem is a system, that is, a set of elements that interact with each other, in which such elements are: physical environment, living beings and their interactions (predator-prey, parasite-host, competition, symbiosis, pollination, distribution of seeds , etc.) The interrelation between living beings (competition, parasitism, etc.) occurs through cycles of matter and energy flows on which the functioning of the entire ecosystem depends.
What cell function can fail resulting in cancer development?
Answers
Answer:
cell division
Explanation:
Cancer is unchecked cell growth. Mutations in genes can cause cancer by accelerating cell division rates or inhibiting normal controls on the system, such as cell cycle arrest or programmed cell death. As a mass of cancerous cells grows, it can develop into a tumor.

Answers
Answer:
Yes.
Explanation:
The creation of one type of kidney cell will be sufficient in forming a functioning kidney because one type of cells allow the kidney to perform its one function i.e. filtering of blood. Epithelial stem cells are the cells that is responsible for the function of a kidney. The kidneys have only epithelial stem cells which performs only one function which removing water material, excess salts and water from the body. so we can say that one type of kidney cell is sufficient for the functioning of kidney.

Which is an example of genetic diversity? PLS HELP temperate rain forest and a tropical rain forest bees, jack rabbits, diamondback rattlesnakes bacteria, garter snakes, tigers variations in a flock of starlings
Answers
Answer:
temperate rain forest and a tropical rain forest bees.
Explanation:
The temperate rain forest and a tropical rain forest bees is the example of genetic diversity because the same organisms has different features which allows them to live in different climatic conditions due to their variation in genetics. The environment of temperate rain forest is different from tropical rain forest so the bees specie that live in both environment are different from one another in their genetic makeup and which is an example of genetic diversity.
Which is of the following is necessary for natural selection? 1. There must be a shortage of food 2. There must be a change in the environment, causing individuals to change 3. There must be some genetic differences among the individuals of a species 4. all of the above
Answers
Answer:
It's 3!
Explanation:
There must be genetic differences so the best fitted organisms will survive. If they were all the same then no one would be best fitted and Natural Selection wouldn't be able to occur
It's not 1 because a food shortage isn't required, there's always competition for food sources
It's not 2 because there doesn't need to be a change in the environment for natural selection, just for evolution.
And it can't be 4 if 1 and 2 are wrong!

The diagram below shows two processes, P and Q, in the carbon cycle.
Which of these statements best describes the processes P and Q?
P shows diffusion and Q shows weathering.
P shows weathering and Q shows diffusion.
P represents combustion and Q represents decomposition.
P represents decomposition and Q represents combustion.
Answers
Answer:
P shows diffusion and Q shows weathering.
Explanation:
The process shown in the image attached to this question is a part of the carbon cycle. Based on the image in this question, atmospheric carbon enters the ocean in a process called P while carbon deposited in limestone is released into the atmosphere via a process called Q.
- Atmospheric carbon which is carbon dioxide (CO2) enters the surface of the ocean via a process called DIFFUSION, hence, process P shows diffusion
- Also, for the carbon in limestone to be released into the atmosphere, the limestone has to be broken down in a process called WEATHERING. Hence, process Q shows weathering.

____ Air is drawn into the lungs
____ Air pressure in the chest cavity decreases
____ Lungs expand
____ The diaphragm contracts and flattens
____ The muscles between the ribs contract to move the ribs up and out
Answers
Answer:
air is drawn into the lungs
lungs expand
the muscles between the ribs contract to move the ribs up and down
air pressure in the chest cavity decreases
the diaphragm contracts and flattens
Inhalation has been part of respiration. It includes drawing air into the lungs that expand the lung cavity by pulling the ribs leading to contracting the diaphragm followed by a decrease in lung pressure. Thus the correct order is 1, 3, 5, 4, and 2.
What is inhalation?Inhalation is the respiratory process to inhale oxygen inside the respiratory system for the cellular and respiratory processes. At first, the air is drawn into the lungs followed by expansion of the lungs.
This causes the ribs muscles to move up and down to accumulate the volume. This movement causes the diaphragm to flatten and contract which allows the oxygen to take place in the lungs that decreasing the air pressure in the cavity.
Therefore, the air is drawn inside the lungs in inhalation.

why do large organisms require a transport system?
Answers
Answer:
Larger animals have a lower surface area to volume ratio. This means they need transport systems like our circulatory system and exchange surfaces like our lungs or fish gills. In single-celled organisms such as protists, and small multicellular organisms, essential molecules will move to where they're needed by diffusion.
Explanation:
Answer:
As the size of an organism increases, its surface area to volume ratio decreases. ... Large multicellular organisms therefore cannot rely on diffusion alone to supply their cells with substances such as food and oxygen and to remove waste products. Large multicellular organisms require specialised transport systems.

in pea plants, purple are dominant to white.
complete the chart showing the genotypes and phenotypes possible.
someone help me i’m kinda lost on how i do this
Answers
Answer:
PP (genotype) - Purple (Phenotype)
Pp (Genotype - Purple (Phenotype)
pp (Genotype) - White (Phenotype)
Explanation:
The genotype allele combinations, in order to for purple to be dominant there are three possible genotypes
*Capital P represents a purple dominant allele
*Lowercase p represents a white recessive allele
(Alleles are the variants of a certain gene, ex: brown eyes, green eyes, etc. )
A Dominant always overpowers the recessive, the only way for a recessive to show would be to have two recessive alleles from both parents
ex: Green eyes recessive to Brown
B - Brown bb = green eyes (from dad)
b - green bb = green eyes (from mom)
this means that their child would have green eyes because there is no brown present
So for your pea plants to be purple
Pp = Purple pp = white
PP = Purple (yes there can be white recessive present, it just might not appear as a plant because of the percent of purple)
The colors or observations we see as the plant are the phenotypes
so the colors I have listed would be the phenotypes
Don't get alleles and phenotypes confused, alleles are the various forms of a gene, and phenotypes are what we see when the gene is brought through.
