Answer:
The heart pumps blood through the lungs. In the lungs the blood receives oxygen and releases carbon dioxide. Then the heart pumps this oxygen-rich blood from the lungs to your cells. When the oxygen-rich blood gets to the cells, the cells receive the oxygen and release the carbon dioxide.
The cells in our bodies need oxygen to stay alive. Carbon dioxide is made in our bodies as cells do their jobs. The lungs and respiratory system allow oxygen in the air to be taken into the body, while also letting the body get rid of carbon dioxide in the air breathed out.

Which location has the warmer air temperature: Recife or Lima? Why?
Answer:
Recife has warmer air temperature because it is closer to the equator
Answer:Recife has the warmer air temperature
Explanation:Recife has the warmer air temperature.The first reason is that Recife,Brazil is closer to the equator than Lima,Peru which means Recife will receive more energy from the sun.Another reason is that the ocean currents that pass both locations have different origin.The current that passes Recife originated near the equator so that causes it to bring lots of energy causing the air temperature of Recife to be high and warm.The current that passes Lima originated near the South Pole so that causes it to bring less energy.Also Lima,Peru has upwelling as we see in the map and that also affects Lima,Peru to have colder air temperature

Explanation:
Paul and Jennifer university are stadyingHow does movement of the legs affect the gills of crabs?
Answer:
The beating or fanning movements of three pairs of maxilliped flagella in crabs and crayfish modify exhalent gill currents while drawing water over chemoreceptors on the head. They play an integral part both in signalling by distributing urine odours, and in active chemosensation.

Explanation:
Huntington's disease, which causes degeneration of neurons, runs in Mark's family. Huntington's is a heritable, autosomal dominant genetic disease. In an autosomal dominant disease, only one abnormal allele is required to cause the disease in offspring. However, it is possible that not all offspring will receive the abnormal allele from an affected heterozygous parent. Family members that have the disease include Mark's maternal grandfather and Mark's maternal aunts. Mark's maternal grandmother does not have the disease. Because symptoms of Huntington's disease do not appear until later in life, genetic testing is necessary to determine whether a younger individual possesses the allele for the disease. These tests determined that Mark's mother does not carry the allele for Huntington's disease. Mark's paternal aunt suggested that Mark create a pedigree to track the disease in his family. Use the symbols provided to complete the pedigree. Each symbol may be used more than once.
Answer:
The correct answer is - maternal grandmother unaffected, maternal father affected, two maternal aunts affected, mother not affected and paternal side not affected so Mark is also not affected. (check the image)
Explanation:
As we know Mark's paternal grandparents do not have Huntington's disease. If the grandparents are normal the father and paternal aunt of Mark does not carry the disease allele therefore the symbols on the right represent Mark's paternal family.
We also know that the grandfather from the maternal side is affected and maternal aunts also have Huntington's disease, it is found out by the genetic testing that the mother is unaffected which means Mark will be unaffected as well as mother and father both are normal.
maslows theory of self actualization
Answer: OK Maslow's quote refers to self-actualization, which is the highest level or stage in his model of human motivation: the 'Hierarchy of Needs'. According to the hierarchy of needs, self-actualization represents the highest-order motivations, whiSelf-actualization, in psychology, a concept regarding the process by which an individual reaches his or her full potential. ...

In poultry, two genes, R and P, control the shape of the comb on the head. The following genotype/phenotype relationship applies to these two genes: R- P- animals have a 'walnut' comb; R- pp animals have a 'rose' comb; rr P- animals have a 'pea' comb; rr pp animals have a 'single' comb. What will the comb phenotypes of the progeny be for a cross of rr PP X rr Pp animals

If a flower is wilting, which structure inside its cells lacks water?
vacuole
cell wall
carpel
chloroplast
Answer:
Vacuole
Explanation:
The central vacuole stores water in the cell and helps maintain water pressure, or turgor pressure, within the cell. The plant wilts because the central vacuole is empty and the cell is partially collapsed. Once the plant is watered and the central vacuole is full again, the plant will return to its normal position and appearance.
At carrying capacity, the number of organisms being born equals the number of organisms
competing
dying
surviving
immigrating
Answer:
dying
Explanation:
carrying capacity is where there is only a certain amount animals can enter so the animals being born is the same as the animals dying bc they have no resources

mRNA Codon chart Using the above chart, name the amino acid that is coded for by a strand of DNA: CCA O Alanine O Arginine Isoleucine O Proline
Answer:
[tex]\boxed {\boxed {\sf Proline}}[/tex]
Explanation:
We are given a codon (set of three nucleotides) and asked to find the amino acid it codes for.
There are a few types of charts that can be used, for example, the circular one attached starts in the middle and goes outward. Follow the sequence of the three letters from the center.
Another chart attached can be used. For this, we must find the intersection of the three letters. Located the 1st letter on the left, the 2nd on the top, and the 3rd on the right.
Based on both charts, proline is the correct amino acid.
