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

Answer:

Almost all the rest of Minnesota's electricity generation comes from wind, which supplied 19% of the state's electricity net generation in 2019, and natural gas, which fueled 18%. Smaller amounts of electricity are generated from solar energy, biomass, and conventional hydropower.

Natural Selection and Genetic Drift

evolution refers to the change in the characteristics of a species over several generations and relies on the process of natural selection.

there are four types of mechanism of evolution:

the mechanism of evolution could involved in the evolution of wolves and dogs are:

natural selection and genetic drift

natural selection favored wolves that were bold and friendly. bold and aggressive wolves would be killed and hence unable to breed. this allowed bold and friendly dogs to breed, which was key to eventual evolution into dogs.

Answer:

D. motion

Explanation:

Force is something that acts on an objects (e.g gravity)

Speed is how fast something moves

Velocity is sort of like speed and is the rate of change of an objects position

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!

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.

Answer: dna replication happens in interphase before the mitosis

Explanation: During interphase the cell’s DNA inside the nucleus replicates forming two strands of DNA or chromosomes. In the interphase the DNA replicates in the S phase. Don’t confuse with G1 since in G1, which comes before S phase, replicates the cellular contents needed for this process

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.

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.

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.

Explanation:

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.

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.

Answer:

The hemoglobin was below normal, and the hematocrit was normal.

Explanation:

Hemoglobin is an essential protein in the bloodstream, as it is primarily responsible for the transport of oxygen throughout the body. It is also responsible for the red coloration of the blood, as it is present in the red blood cells. The hematocrit, in turn, is a laboratory parameter to determine the amount of red blood cells in the blood and also to determine the total blood volume.

Although the results presented by the hematocrit are important in determining whether a person has anemia, women with normal hematocrit values may be anemic, primarily because the hematocrit results may be associated with the amount of water in the blood. What is essential to determine if a woman is, in fact, with anemia, due to iron deficiency, is the hemoglobin values that are below normal.
