The hemoglobin protein of a human and a frog differ by 67 amino acids. How many amino acids are most likely different between a human and a chimp?
A. none
B. fewer than 67
C. 67
D. more than 67
Answer:
B. Fewer than 67
Explanation:
Humans are much more closely related to chimps than frogs, so the genetic information that codes for their proteins will differ much less.
Based on the evolutionary relationship between humans and chimpanzees, it is highly likely that humans and chimpanzees share a large portion of their genetic material, including the amino acid sequence of hemoglobin. Therefore, it is most likely that the answer is B. Fewer than 67 amino acids are different between a human and a chimp.
What is the hemoglobin of different animals?The hemoglobin protein is a vital protein in both humans and chimpanzees that helps transport oxygen in the blood. While there may be some variations in the amino acid sequence of hemoglobin between humans and chimpanzees, it is expected that most of the amino acids will be the same since hemoglobin performs a critical function in both species. Additionally, any differences in the amino acid sequence of hemoglobin between humans and chimpanzees are likely to be fewer than 67, as this is the number of differences between humans and frogs, which are much more distantly related species.
Hence, it is most likely that the answer is B. Fewer than 67 amino acids are different between a human and a chimp.

Explain your justification for the changes in trait distribution between years 1 and 10. What do you think will happen to the population by year 15?
Answer:
It will continue to rise.
Explanation:
Genetic variation results in the changes in trait over the period of time. Hence, traits do change over the years, but it is a gradual process. The population will become more stable due to successful traits.
What is genetic variation?Genetic variation refers to the changes in the genotype of an individual. It imparts stability to the population. Genetic variation results from meiotic cell division where recombination of gene produces genetic exchange of heredity material.
Those traits which are successful in nature that means those variations which provide stability to the organism in any environment are favoured. Organisms with such variations adapt, survive and further reproduce to continue their existence. Such traits are transmitted to the progeny as well.
Thus, gradual accumulation of changes in traits contribute to a more stable population over the span of years.
Therefore, changes in traits are important in determining the track of evolution on earth.

Using the words "selection pressure" and "fitness", explain how natural selection causes populations to change over time.
Answer:
Environment and competition is the leading cause of evolution. It's an instinct to want to live, but trying to survive is difficult when other animals have the same goal. An ecosystem is a cycle, but every generation of this ecosystem slightly changes, and so do the animals. Every bug that has fitness can start overpopulating the ecosystem, leading to a surge of resources for what preys on the bug. Now bird's population goes up, so do other animal populations. Or the bug becomes an invasive species, and birds are being hunted too often to decrease the population.
In a different scenario, bugs are evolving because of the selection pressure that the environment is giving them. The birds have become better over the generation, and now have a more suited beak to catch the bug off the ground. The bug population maybe be decreasing, but the ones who live through the crisis are populating with bugs that certain gene that helped them out. But it's not over, the bug population isn't declining but it wasn't as big as it was before. The bird will find more ways to find and capture the bugs. But then bugs will keep surviving through the selection pressure and become much harder to find since they figured out camouflage. The bug that was neon yellow was dying since they were easy to see. Now they can range from green to black to hide in the environment. Now the birds are facing the selection pressure, it's a cycle.

What is the measured output force of a pulley system if the Mechanical Advantage is 0.48 and measured input force is 10N?
Answer:
Output force is 4.8 N
Explanation:
A pulley is a simple machine made of a grooved wheel with a rope or cable wrapped around it. Pulleys are used in the transmission of energy or motion.
The input force is also known as the applied force while the output force is the force exerted on an object by a simple machine.
The mechanical advantage of a pulley is the ratio of the output force to the input force.
Mechanical advantage = output force / input force
Substituting:
0.48 = output force / 10
Output force = 4.8 N
James needed to have his hernia surgically repaired. This can be done through laparoscopic surgery. The surgeon must cut through to the herniated area and put a Teflon mesh underneath the hernia to close it off and provide more support to the area. Use your knowledge of anatomy to select the correct sequence of structures that would be cut for this procedure. Make sure you select the structures in the order they would be cut by the surgeon.
Answer:
The structures that the surgeon will cut to place the Teflon mesh from external to internal are:
Skin,
hypodermis,
subcutaneous fat,
the external oblique aponeurosis,
the internal oblique,
the transverse abdominal,
the peritoneum.
Explanation:
For the surgeon to put the Teflon mesh underneath the hernia, the professional has to cut the most external organ, which is the skin, with all its layers, epidermis, dermis, and hypodermis. Underneath this tissue is the subcutaneous fat, which protects the muscles, regulates the temperature, and stores energy. Subcutaneous fat is different in every person. Some can have a lot of it and others a thin layer. The next cut will be on aponeurosis, which is a tissue that surrounds muscles. Then we have the internal abdominal oblique, which is in the anterior area of the abdomen. Below it, it is the transverse abdominal, and then the peritoneum, which is the tissue that holds the organs. In a hernia, it has a hole where the organs push through. So, the surgeon has to put a Teflon mesh to close it.
What type of transport was shown in the second animation?
A. active transport with the help of transport proteins
B. passive transport by simple diffusion across the membrane
C. passive transport by facilitated diffusion with the help of transport proteins
Answer:
C. passive transport by facilitated diffusion with the help of transport proteins
Explanation:
The electron transport chain (shown in the second animation) establishes a proton gradient across the inner mitochondrial membrane. ATP synthase uses the energy stored in the proton gradient to catalyze the synthesis of ATP. The molecular machinery involved in this process converts chemical energy to mechanical energy and provides a great example of the relationship between the structure and function of macromolecules.
Answer:
C. passive by facilitated diffusion with the help of transport proteins
Explanation:
Passive transport is a type of membrane transport that does not require energy to move substances across cell membranes.

A tropical rainforest includes trees, animals, insects, plants, rain, rivers, rocks, soil, and warm, moist air.
Which spheres of Earth are represented in a tropical rainforest?
O biosphere, geosphere, hydrosphere
O cryosphere, hydrosphere, ionosphere
O geosphere, biosphere, cryosphere
ionosphere, hydrosphere, geosphere
Answer:
The answer is A
Explanation:
The hydrosphere provides almost all the water at or near the earth's surface. It is important to the biological and geological processes as it is a continuous cycle of recycling water between the oceans and atmosphere.
A tropical rainforest is a representation of the Earth's biosphere, geosphere, and hydrosphere, hence option A is correct.
What are the spheres of Earth?Trees, animals, insects, rivers, rocks, soil, and warm, humid air make up the tropical rainforest. The ecosystem, which consists of both living organisms (animals) and inanimate objects, is referred to as the biosphere.
This encompasses ecosystems where there are rocks and other buried minerals, such as those found in tropical rainforests.
The hydrosphere is also accurately represented in the tropical rainforest since there are rivers and rain there.
Therefore, we may deduce that a tropical rainforest represents the biosphere, geosphere, and hydrosphere of the planet.

Distinguish between gaseous exchange and respiration
Answer:
Respiration is the process in which food is oxidized to release energy. Complex organic compounds are converted into simpler ones, e.g glucose into CO2 water and energy released. Gaseous exchange is the diffusion of gases from a region of higher concentration to a region of lower one.
Explanation:
Breathing is the physical process by which air is passed on a gaseous exchange surface i.e. ventilation of the gaseous exchange surface. It involves Inhalation and Exhalation.
Gas/Gaseous exchange is the process whereby gasses diffuse across a gaseous exchange surface. In humans, oxygen diffuses from the inhaled air into the blood and carbon dioxide diffuses from the blood into the exhaled air. The gaseous exchange surface here being the Alveoli.
Respiration is the metabolic process whereby organic molecules are broken down to release energy in the cells. In humans, this process takes place inside the mitochondria of cells. Aerobic respiration requires oxygen whereas qnqerobic respiration takes place in absence of oxygen.
