Phenomenon: Miss Westbrook visited family in Aspen last spring. Aspen is in Colorado and has an elevation of 8,000-9,000 feet. The Bay Area has an elevation of 0-100 feet. Miss Westbrook’s breathing and heart rate both sped up every time she went hiking or skiing in Aspen. Why do you think this happened?
Hint: Your brain regulates the rate and depth of your breathing to match the needs of your body for 02 intake and CO2 removal.
Breathing rate refers to the number of breaths per minute.
This happened due to the low air pressure in the highest areas of Colorado, which made hard the intake of air.
Air pressure is fewer as the elevation in an area increases. In other words, the air over us is less, so the pressure that it makes is lower.
Miss Westbrook's heart rate and breathing sped up due to the low air pressure that she experimented with when ascending or when skiing in Aspen, which is very elevated. As the pressure is lower, not much air can enter the lungs, so her brain increases the breath rate to obtain the same amount of oxygen that her body had when breathing normally on the Bay. As there is not enough oxygen in her body, the brain also increases the heart rate to match the rhythm of the breath and deliver the scarce oxygen to the different parts of the body.
In conclusion, the increase in the heart and breath rate happens due to the low air pressure in elevated areas that makes our body find ways to compensate for the decrease in the amount of oxygen that our body can take.

How does sympatric speciation differ from allopatric speciation?
Symaptric speciation is the formation of new species in populations that live in the same geographic area, while allopatric speciation occurs when the population is separated by a geographcial area. So, according to this: The difference between the sympatric speciation and the allopatric speciation is that sympatric speciation involves a behavioral barrier, while allopatric speciation involves a physical barrier.

Suppose two leaf-eating species of animals live in a habitat where there is a severe drought and many plants die as a result. Which term describes the kind of relationship the two species probably will have?.
Competition is the kind of relationship these two leaf eating species of
animals will have.
Competition involves organisms vying for resources such as food, sunlight,
space etc in the ecosystem. The two leaf eating animal species are in
competition with each other for plant leaves.
When drought occurs and the leaves reduces, competition for food
increases in which the fittest survive and the less fit ones die from starvation.

How do coral reefs help with climate stability?
They need vast amounts of carbon dioxide for energy.
They support mangroves and seagrasses that release carbon.
They are habitats for species that build exoskeletons from carbon.
They release atmospheric carbon that organisms use to live and grow.
The coral reefs help with climate stability because they serve as homes for species that build exoskeletons from carbon.
Carbon in the form of carbon dioxide has been reported to be a major factor in the climate instability of the planet. This is because they are parts of the greenhouse gases that form a blanket layer over the atmosphere and prevent reflected sun rays from escaping back to space.
Thus, greenhouse gases cause the earth's atmosphere to warm up, a phenomenon known as global warming. The warming, in turn, leads to the unpredictability of several climatic factors.
With the majority of the species living in coral reefs helping to make use of carbon dioxide to build their exoskeleton, they are helping to reduce the concentration of the gas in the atmosphere and thereby reducing warming and erratic climatic changes.

A child watches an older sibling playing with a ball but makes no effort to participate in the play. Which social character is the child exhibiting
Answer:
Onlooker play
Explanation:
In onlooker play a child actively observes other children playing and does not attempt to enter into the activity; the child is interested only in observation and not in participation. In parallel play children play independently among other children. In pretend play children act out any event of daily life and practice the roles and identities as established in their surroundings. In associative play children play together and are engaged in a similar or identical activity.

*What is the relationship between DNA and gene expression? How do they depend on each other?*
Answer:
Gene expression is the process by which the instructions in our DNA are converted into a functional product, such as a protein. When the information stored in our DNA? is converted into instructions for making proteins? or other molecules, it is called gene expression
Explanation:
DNA makes genetic expression. DNA is a structure located in the nucleus that makes people themselves. DNA is unique to everyone, no two people are exactly the same. The way the DNA is structured and what instructions it was given affect one's genetic makeup.

The suncoast tree of northwest Africa is known for 2 traits that are said to show simple dominance. The 2 traits are height and bark color. In height, tall is dominant to short, and in bark color blue is dominant to purple. What would the genotypes be of a suncoast tree that is pure bred purple and tall and a suncoast tree that is heterozygous for both traits?
A. bbTT X BbTt
B. BBtt X BBTT
C. bbtt X bbtt
D. BbTt X BbTt
The genotypes would be bbTT X BbTt
Assuming that bark color is represented by B (b) allele and height is represented by T (t) allele.
Since the traits show simple dominance: blue (B) of dominant over purple (b) and tall (T) is dominant over short (t)
The genotype of a tree that is purebred purple (bb) and tall (TT) would be bbTTThe genotype of a tree that is heterozygous for both trait would be BbTtThus, the cross would be bbTT x BbTtMore on genotypes can be found here: https://brainly.com/question/20730322?referrer=searchResults
3. What challenges do older generations face?
Answer:
Health problem. As aging occurs, the more weak and unstable the body gets.
Unporportionate generation distribution. Some older generations are larger than the ones that precede it, thus, making it harder to have the proper resources to take care of older generations.
Technology. It is harder for older generations to be up-to-date on technology. This can make it harder for older generations to function in society properly.

abundant?
please help
The most abundant in the body is cells.
What do you mean by cells?Cell is the smallest unit that can live on its own and that makes up all living organisms and the tissues of the body. A cell has three main parts: the cell membrane, the nucleus, and the cytoplasm.
Moreover, they provide structure for the body, take in nutrients from food, convert those nutrients into energy, and carry out specialized functions. Cells also contain the body's hereditary material and can make copies of themselves. Cells have many parts, each with a different function.
There are two main types of cells: prokaryotic cells and eukaryotic cells. Prokaryotic cells include bacteria and archaea. Prokaryotes—organisms composed of a prokaryotic cell—are always single-celled (unicellular). Prokaryotic cells don't contain a nucleus.

What kind of trait is dimples?
Hereditary characteristics can be either dominant or recessive, as is the case with humans . Chromosome 5 is thought to be the location of the dominant gene responsible for the inheritance of cheek dimples, while chromosome 16 is thought to be the location of the dominant gene responsible for the inheritance of chin dimples.
It is generally accepted that dimples are caused by a dominant genetic feature, which indicates that the presence of only one mutated copy of a gene in each cell is required to produce the trait. On the other hand, there are academics who argue that there is no evidence to support the theory that dimples are inherited.
