What are the weaknesses or inaccuracies in the
model the student created?
Answer:
The model doesn’t clearly show that gas exchange happens in the alveoli through the capillaries. The model can also be easily misinterpreted. Because the model doesn’t show where this gas exchange is taking place, it looks like the blood picks up oxygen, delivers it to the body, and then comes back and expels the carbon dioxide it collects. Clarifying that this gas exchange is taking place in the capillaries would eliminate this confusion.

What are blood vessels?Blood vessels are channels that carry blood throughout your body. They form a closed loop, like a circuit, that begins and ends at your heart. Together, the heart vessels and blood vessels form your circulatory system. Your body contains about 60,000 miles of blood vessels.
There are three types of blood vessels:Arteries carry blood away from your heart.Veins carry blood back toward your heart.Capillaries, the smallest blood vessels, connect arteries and veins.

Determine whether each occurrence is a result of short-term or long-term change. Sort each one to the correct
category.
speciation
Short-Term Change
Long-Term Change
adaptation
loss of habitat
extinction
forced migration
Answer:
Adaptation and extinction occur as a result of long term change whereas loss of habitat and forced migration results of short term change.
Explanation:
Adaptation and extinction occur as a result of long term change in the environment whereas loss of habitat and forced migration is a result of short term change in the environment. Adaptation occurs in the organism as a result of climate change because when the climate change occurs some organisms are extinct due to intolerance of the change environment whereas some organisms adapt the environment by making some changes its physical structure in order to survive. Loss of habitat and forced migration occurs due to sudden big change in the environmental conditions such as flooding and volcanic eruptions.

A group of white, grey, and black rabbits lives in Alaska, where there is usually snow on the ground. Wolves that hunt the rabbits end up mostly catching ones with grey and black fur. As a result, white rabbits become more prevalent in the population. This is an example of:
Answer:
Directional selection
Explanation:
Natural selection is the process by which environment selects from a population of organisms which individuals are better suited and adapted to that environment. There are three types of natural selection namely: directional selection, disruptive selection and stabilizing selection.
Directional selection is the type of natural selection in which only one extreme (phenotype) of a population is favored over the other extreme and intermediate individuals. This is the case in the example given in the question where among a group of white, grey, and black rabbits that lives in Alaska, environment selects the white rabbits (one extreme) from wolf predation, hence, causing the white rabbit population to increase and be favored.

In a certain species of plant, the allele to produce green melons (G) is dominant over the allele to produce yellow melons (g). A student performed a cross between a plant that produced green melons and a plant that produced yellow melons. When the student observed the next generation, the 94 seeds that were produced from the cross matured into 53 plants with green melons and 41 plants with yellow melons. Calculate the chi-squared value for the null hypothesis that the green-melon parent was heterozygous for the melon-color gene.
Answer:
4.26
Explanation:
Let the green-melon parents be Gg, then we expect the cross with the yellow-melon plant gg so as to produce 50% Gg and other 50% of gg offspring. What we observed was that 53 green and a 41 yellow. Based on the total number of 94 offspring , we expected half and a half ratios to be 47 of each color.
Observed(o) Expected(e) (o-e) [tex]$(o-e)^2$[/tex] [tex]$(o-e)^2/e$[/tex]
Green-melon plant 53 47 6 36 0.766
Yellow-melon plant 41 47 -6 36 0.766
Therefore the chi-square value is 1.53 which is less than the critical value of 3.84. Therefore, the null hypothesis is accepted.

Height, skin color and eye color are all inherited following which of the following inheritance patterns?
a) codominant
b) incomplete dominance
c) sex linked
d) polygenic
Answer: D) Polygenic
Explanation: Polygenic inheritance describes the inheritance of traits that are determined by more than one gene. These genes, called polygenes, produce specific traits when they are expressed together. Polygenic traits have many possible phenotypes (physical characteristics) that are determined by interactions among several alleles. Examples of polygenic inheritance in humans include traits such as skin color, eye color, hair color, body shape, height, and weight.

Which blood test would be ordered?
Answer:
A fasting blood sugar test will be ordered.
Explanation:
A fasting blood sugar test or a glycated hemoglobin test is ordered in such situations. Additionally, tests to determine the insulin level as well as an ophthalmic investigation to determine diabetic retinopathy are ordered. Blood sugar level less than 100 mg/dl is classified as normal. A person is pre-disposed to diabetes if his blood sugar level is between 100-125 mg/dl.
A confirmed case of diabetes mellitus will have a fasting blood sugar level, 126 mg/dl and higher. Insulin administration and a proper management of diet are essential in managing the condition.

Explain the differences between eukaryotic and prokaryotic cells.
Explanation:
Comparing prokaryotes and eukaryotes
All life on Earth consists of either eukaryotic cells or prokaryotic cells. Prokaryotes were the first form of life. Scientists believe that eukaryotes evolved from prokaryotes around 2.7 billion years ago.
The primary distinction between these two types of organisms is that eukaryotic cells have a membrane-bound nucleus and prokaryotic cells do not. The nucleus is where eukaryotes store their genetic information. In prokaryotes, DNA is bundled together in the nucleoid region, but it is not stored within a membrane-bound nucleus.
The nucleus is only one of many membrane-bound organelles in eukaryotes. Prokaryotes, on the other hand, have no membrane-bound organelles. Another important difference is the DNA structure. Eukaryote DNA consists of multiple molecules of double-stranded linear DNA, while that of prokaryotes is double-stranded and circular.
A plant has alleles for white, red, and blue flowers. The majority of the flowers are white, though the color
does not give those flowers an advantage. What might cause this to occur?
Answer:
Environmental factors
Explanation:
If the plant has alleles for all three flowers but only one occurs, then it is most likely a result of tempature or soil pH.

What can we do in lieu of a breathable atmosphere
Answer:
Explanation:
I wonder how you would explain that both men and women are living much longer. In 1900 the average ago of mortality was 42 years old in the United States. We have nearly doubled that. In the province (Canada) where I live the mortality rate is nearly 81 years old. That is a huge improvement.
We have done in spite of contaminated air, oceans that resemble sewage sump (there is a plastic dump the size of Texas somewhere in the Pacific and the Atlantic is little better), a population increase that is unbelievable in terms of %. I wish my stocks would show that kind of % increase, and the current biological crisis -- I'm not allowed to name it. (There have been several of these pandemics since 1900.)

Answer:
apes are very related to humans. there's only one difference in their dna sequence.
sharks are least related to humans because we diverged from them a long time ago through divergent evolution.
humans and apes share homologous structures such as arms, legs, tailbone, and fingers that are similar in function.
the differences between humans and apes are that they have a tail, whereas we do not, and their vocal cord hasn't evolved as much as ours.
apes are more vulnerable since they can't innovate weapons and defend themselves with tools like we once did.
humans are more likely to survive because we are strong in number, and our teamwork can triumph any challenges.
There are several buffer systems involved in maintaining blood pH, but one is more important than the others for maintaining acid-base homeostasis in blood. To understand why an acid-base imbalance in the blood results from respiratory depression, you must first identify the major buffer system responsible for controlling blood pH. Which equilibrium reaction is the most important for maintaining acid-base homeostasis in the blood?
Answer:
The Carbonic-Acid-Bicarbonate Buffer. In animals with lungs, the carbon / bicarbonate buffer system is especially effective. In these animals, the H2CO3 in the blood plasma is in equilibrium with the gaseous CO2 present in the airspace of the lungs, which represents a practically unlimited reserve of CO2 that can participate in the equilibrium.
Explanation:
In the Carbonic-Acid-Bicarbonate buffer system, 3 reversible equilibria take place between the CO2 gas in the lungs and the bicarbonate dissolved in the blood. The bicarbonate ion (HCO3-) can combine with a proton (H +) to form carbonic acid (H2CO3), thus absorbing protons from solution and raising blood pH. Carbonic acid, which can be formed from CO2 and water, can dissociate into H + and HCO3- to provide H + and lower blood pH. Carbonic acid, which can be formed from bicarbonate, is converted to CO2 and water by a very fast enzymatic reaction. CO2, being volatile, can be rapidly eliminated from the body in variable amounts through respiration.In the clinic, the system that is measured for the assessment of the acid-base status is the carbonic / bicarbonate system.
