Explain how specific membrane-bound organelles of the keratinocytes are used to produce, transport, and modify aquaporin polypeptides from mRNA.
Answer:
Epidermis.
It is composed of keratinized, stratified squamous epithelium and is made up of 4 layers of epithelial cells depending on its location in the body. From deeper to superficial these layers are stratum Basale, stratum spinosum, stratum granulosum, and stratum corneum. The cells in all the layers except for stratum besele are called keratinocytes which is a cell that manufactures and stores the protein keratin.
Stratum Basale.
It is a cuboid-shaped stem cell that is a precursor of the keratinocytes of the epidermis. Two other cell types found in this basal cell are Merkel cells which function as a receptor and are responsible for stimulating sensory nerves that the brain perceives as touch. The second is melanocyte that produces melanin pigment which gives the skin its color.
Stratum spinosum.
It is spiny in appearance due to the protruding cell processes that join the cells via a structure called desmosome. The desmosome cell interlock with each other to strengthen the bond between the cell. Keratinocytes in the stratum spinosum stats synthesizing keratin and release water-repelling glycolipid that helps to prevent water losses from the body.
Stratum granulosum.
They are grainy in appearance due to further change in keratinocytes as they are pushes from the stratum spinosum. The cells become flat as their membrane thickens to allow the production of protein keratin which accolades as lamellar granules within the cells.
Stratum Lucidum.
It is a smooth and translucent layer of the epidermis situated above the stratum granulosum. Keratinocytes containing these cells are dead and flat. Stratum lucidum cells are packs with eleiden derived from keratohyalin which give these cells their transparency and provide a barrier to water.
Stratum corneum.
This is the most superficial layer in the epidermis and it prevents penetration of microbes and dehydration of underlying tissues.
Dermis.-This is the inner layer of the skin and has the following functions.
Reticular layer
Just below the papillary layer, we have a much thicker layer called the reticular layer composing of dense connective tissue. It contains elastin fibers providing elasticity to the skin enabling movement.

Explanation:
As carbon dioxide is added to the atmosphere, more carbon dioxide also enters the ocean through diffusion. Carbon dioxide reacts with water to produce carbonic acid, which lowers the pH of the water. What effects do you think this might have on marine life?
Answer:
As the amount of carbon dioxide in the atmosphere rises, the oceans absorb a lot of it. In the ocean, carbon dioxide reacts with seawater to form carbonic acid. This causes the acidity of seawater to increase.
As we have seen, coral reefs have been bleached because of this increased in acidity
The oceans absorb a significant amount of carbon dioxide as the amount in the atmosphere increases. Seawater and carbon dioxide react in the ocean to produce carbonic acid. Seawater's acidity rises as a result of this.
What is acidification?Acidification is defined as a phenomena that happens when some chemicals release protons into the environment. Ocean acidification is mostly brought on by atmospheric carbon dioxide gas absorbing into the ocean. The pH of the water is lowered as a result, increasing the acidity of the ocean. The amount of carbon dioxide is rising due to numerous factors.
More carbon dioxide is evaporating into the ocean as a result of human-driven increases in atmospheric carbon dioxide concentrations. Currently, the ocean has an average pH of 8.1, which is basic (or alkaline), but when more CO2 is absorbed, the pH drops and the ocean turns more acidic.
Thus, the oceans absorb a significant amount of carbon dioxide as the amount in the atmosphere increases. Seawater and carbon dioxide react in the ocean to produce carbonic acid. Seawater's acidity rises as a result of this.

Pick out the sentences that correctly describe marine mammals.
Marine mammals are endothermic, or warm-blooded. Species such as whales breathe air though their gills. They have a thick layer of blubber
that helps maintain buoyancy. They can stay underwater indefinitely. Dolphins are a type of toothed whale. Baleen whales feed on large fish
and sometimes seals.
Marine mammals are endothermic. I think that's the correct answer 'cause they can produce their own body heat (which therefore means that they are warm-blooded) and they can keep at a stable temperature even in harsh conditions. Plus, whales don't have gills b/c they are mammals (and mammals don't have gills), not all mammals have blubber (it's mainly penguins and seals), marine mammals can stay underwater for a long amount of time...but they eventually need to come up for air, and baleen acts like a "filter"; it "filter" and separates the water from the krill/microorganisms.
Hope this helps! :)

A plant and an animal are both living things. According to the Cell Theory, what can you conclude about these two
very different organisms? SC.912.L.14.1
Plants have cells but animals do not
They are both made of one or more cells.
They both come from the same kind of cell.
O They both come from a non-living organism.
Answer:
They are both made of one or more cells.
Explanation:
A plant and an animal are both living things. According to the Cell Theory, what we can conclude about these two very different organisms is that they are both made of one or more cells.
A cell can be defined as the fundamental or basic functional, structural and smallest unit of life for all living organisms. Some living organisms are unicellular while others are multicellular in nature.
A unicellular organism refers to a living organism that possess a single-cell while a multicellular organism has many (multiple) cells.
Generally, cells have the ability to independently replicate themselves.
In a cell, the "workers" that perform various functions or tasks for the survival of the living organism are referred to as organelles and they include nucleus, cytoplasm, cell membrane, golgi apparatus, mitochondria, lysosomes, ribosomes, chromosomes, endoplasmic reticulum, vesicles, etc.

When water evaporates from plants through leaves, it diffuses through tiny openings called stomatal pores. If the water vapor needs to diffuse a distance L through one pore to exit the leaf in a time t, what is the time needed for water vapor from the same leaf to diffuse through another pore of length 1.30 L
Answer:
L means same time.
Explanation:
Same time is needed for water vapor from the same leaf to diffuse through another pore of length 1.30 L because the evaporation takes place at the same time in the pore and water is evaporated to the atmosphere but more water is evaporated due to increase of surface area as compared to the other pore that have small opening so the time is same but the amount of water evaporated is different.

Point mutations resulting in a single amino acid substitution provided evidence that: Select one: A. The genetic code is a triplet code. B. The genetic code is overlapping. C. The genetic code is not overlapping. D. The genetic code is degenerate. E. tRNAs recognize codons.
Answer:
C. The genetic code is not overlapping.
Explanation:
The genetic code is nonoverlapping because each nucleotide can be part of only one codon or 'codeword' during protein synthesis. Therefore, a particular point mutation in the nucleotide sequence can result in only one amino acid modification. A nonoverlapping genetic code indicates that the same letter (i.e., the same nucleotide) can not be used for two different codons. The non-overlapping nature of the genetic code was discovered by Tsugita and Fraenkel-Conrat (1960) by observing point mutations in the tobacco mosaic virus.
A change or modification in the single nucleotide base of the genetic material is called a point mutation. It can be either addition, deletion or inversion.
The correct answer is:
Option C. The genetic code is not overlapping.
This can be explained as:
The point mutation in the amino sequence tells that the codons are not overlapping and a single nucleotide is a part of only a single type of codon.A single nucleotide can't be included in two codons.The same letters of the bases purines and pyrimidines are not a part of two different triplets.Therefore, point mutation tells that the genetic code is non-overlapping.
