The order of flow of oxygen within the human body may be described simply. Oxygen first is inhaled through the nasal cavity and then passes through the trachea, through the bronchi and into the lungs. In the lungs, the oxygen is passed into the blood stream through the alveoli and then is carried to the heart. The heart pumps this oxygenated blood throughout the body, primarily to organs and muscle cells, where it is consumed in respiration and is converted to carbon dioxide and excreted.
If a light is traveling straight up out of the ocean, then moves out of the air it will become less refracted because it is moving to a far less-dense medium, meaning the image will not be distorted.
Answer:
<u><em>The correct options are:</em></u>
<u><em>All traits are inherited.</em></u>
<u><em>Offspring inherit one allele for a gene from each parent.</em></u>
<u><em>An offspring with two identical alleles for a trait is homozygous.</em></u>
Explanation:
- In the biological world, a trait can be described as a genetic characteristic which makes up an organism. Every organism has a particular set of traits.
- Traits are inherited from parents, however they can be influenced by the environment.
- The alleles of a gene make up the genotype and the influencing phenotype. An organism acquires one allele for the gene pair from each parent.
- When both the alleles of a gene pair are similar, the organism is said to be homozygous for the trait. If both the alleles of a gene pair are different, the organism is said to be heterozygous for the trait.
Deforestation is people cutting down whole forests of trees, andmaking it even less likely for humans to survive. Trees supplyoxygen, absorb carbon dioxide, and hold down the soil from washingaway or making landslides. The destruction and cutting down of forests is often done to clearland for farming, mining, roads, and grazing of cattle. That causesincreased atmospheric CO2 levels, a factor in global warming.
