(b) Describe the characteristics of the interior of the aquaporin channel protein that allow water to flow through AND exclude glucose.
If isolated keratinocytes are placed in a hypotonic solution for 24 hours, explain the net direction of water movement AND why the
rate of water movement slows down over time.
Answer:
Aquaporin protein is a type of protein composed of a bundle of six transmembrane α-helices.
Explanation:
Aquaporin protein is a type of protein composed of a bundle of six transmembrane α-helices. These aquaporin protein have different size of water channels that allow water through to pass through it but it does not allow glucose to move through it due to its large size. The direction of water movement is toward the cell because there is low water inside the cell as compared to outside environment so the water moves inside the cell and rate of water movement slows down over time due to filling of empty spaces with water.
Why are mutations a significant component of evolution and natural selection?
Answer
A
Mutations occur when a population needs a new trait to survive.
B
Mutations are the only source for new alleles in a population’s gene pool.
C
Mutations occur when a species population has become too large.
D
Mutations are a major source of extinction for various species
Answer:
B
Explanation:
process of elimination. The other ones were wrong tbh. Also, in natural selection genetic variation/mutations are a HUGE FACTOR according to darwins 3 principles of evolution.

8. Genetic engineering has directly increased productivity in which
U.S. industry?
Answer:
Agriculture
Explanation:
Genetic engineering can be defined as the use of genetic techniques aimed at modifying the genome of living organisms, thereby being used to develop Genetically Modified Organisms (GMOs). In the USA, genetic engineering methodologies have been used in agriculture to improve crop yields and reduce costs (for example, by reducing the need to use pesticides). Some of the most important genetic engineering techniques that nowadays are being used in agriculture research include biolistic transformation, Agrobacterium-mediated transformation, the CRISPR-Cas9 genome editing system, etc.
Which of the following is involved in the opening of stomata for the gas exchange of the plant?
Answer: Osmotic Pressure, lb/in2
Explanation:
Osmotic pressure is involved in the opening of stomata for the gas exchange of the plant.
What are stomata?In the epidermis of tree leaves and needles, there are cell structures called stomata that play a role in the exchange of water and carbon dioxide between plants and the atmosphere.
Transpiration and gas exchange is made possible by stomata. It is surrounded by two guard cells that regulate how the stomata open and close. Stomata open during the day for gaseous exchange and to release water vapour during transpiration. The stomata open and close in response to changes in the turgor pressure within the guard cell.
Hence, osmotic pressure is responsible for the opening and closing of stomata.

10. Wei saw a special type of plastic that would melt and become a liquid when it was placed in the sun, but it would not melt when placed under a desk lamp. Why does light from the sun melt the plastic when light from the desk lamp does not? Because the plastic can take in energy from the light from the sun but not from the light from the lamp. b Because light from the sun carries heat molecules, and light from the desk lamp does not. Because light from the sun pulls energy out of the plastic, and light from the desk lamp does not. Because the sun gives off a type of light that carries erlergy, and light from the desk lamp does not.
What is the correct amino acid sequence for the
mRNA code AUGCCAGUAUGA
Answer:
UAC GGU CAU ACU
The correct amino acid sequence is Methionine-Proline-Valine-Stop codon.
What is the genetic code?The genetic code is a code that specifies the amino acids that will be added to a protein from a given nucleic acid chain.
Each triplet of nucleotides or codon in mRNA indicates a specific amino acid.For example, the codon AUG specifies the addition of the amino acid Methionine.In conclusion, the correct amino acid sequence is Methionine-Proline-Valine-Stop codon.

In at least 100 words, construct an explanation that predict an organism's ability to
survive within the changing environmental limits.
Answer:
living, components can likewise influence an organic entity's capacity to make due in an environment. They incorporate food accessibility, rivalry with different life forms, plant cover accessibility, predation, sickness, parasitism, swarming, territory discontinuity and the presence of human populaces. An absence of trees can influence populaces of birds or other arboreal organic entities, which may depend on tree cover for settling and stowing away from hunters. Some biotic elements influence abiotic factors also, for example, plants that become taller than contending plants and square daylight, or an absence of disintegrating natural matter or nitrogen-fixing microorganisms that prompts low nitrogen levels in the dirt.
Are viruses abiotic?
Answer:
no because they dont need to consume energy to survive and they cant replicate without a host cell

1. Which of the following mRNA triplets compliments ACC?
a. GAC c. UGC
b. CGG d. UGG
2. What process was involved in number 1?
a. Fertilization b. Replication
C. Transcription d. Translation
Answer:
d
Explanation:
a goes with u
c goes with g
The mRNA triplets compliments ACC is UGG and the process involved is transcription.
DNA transcription
DNA transcription is a process carried out by messenger RNA, which has as its ultimate goal the formation of proteins.
This transcription occurs with the combination of nitrogenous bases, which combine in such a way:
C - G
G - C
A - U
T - A
So, the transcription of the ACC base would be equivalent to UGG, and the process is called transcription.

Answer:
absorption and circulation
Explanation:
While digestive enzymes are produced in numerous parts of the digestive system, the pancreas produces the majority of them.
What is the important role of metabolism in digestive tract?In the digestive tract, digestion and absorption take place. All body cells may access the nutrients after they are absorbed, and the cells use them for metabolism.
The six actions, or functions, of the digestive system prepare nutrients for use by body cells.
The gastrointestinal tract, which was previously mentioned in this study, is a specialized sensory system.
In charge of detecting ingested glucose and relaying information to peripheral tissues or the brain to control glucose metabolism.

Many organisms in the ocean (like plankton) rely on this source of food. What effects do you think this change in the decrease speed of the ocean currents could have on living things on the ocean?
Please help
Answer:
If the speed of ocean currents slows down, some living beings in the ocean would find it difficult to feed and reproduce.
Explanation:
As we already know, ocean currents act as a transport chain that transports hot water to the poles and cold water to the tropics. However, this ability to transport ocean currents also acts in the transport of nutrients and food for living beings that live on the seabed and do not move, but live in a fixed place. They also transport the reproductive cells of these beings to other places in the ocean, being important in the reproduction of marine life. If the speed of ocean currents decreases, the feeding and reproduction of some marine life organisms will be impaired.

Which of the following is true about environmental hazards to humans?
A)
Children are more at risk than adults because they take in more air per unit mass than adults.
B)
Adults are most at risk because they have the highest exposure to environmental hazards.
C)
Elderly people are most at risk because their immune systems do not perform efficiently.
D)
Children are least at risk because they have well functioning immune systems.
E)
Adults are most at risk because they take in more pollutants relative to their size than children.
Answer: A)
Explanation:
Children are at a higher risk of suffering negative effects from environmental hazards than adults, because children do not have fully developed immune systems. In addition, children have a higher exposure to environmental hazards, because they spend more time outside, on average, than adults. Children also take in more air per unit mass than adults, which means that they also take in more pollutants relative to their size.
