Explain how specific membrane-bound organelles of the keratinocytes are used to produce, transport, and modify aquaporin polypeptides from mRNA.

Answers

Answer 1

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.

Hypodermis

Explanation:

Answer 2
KeratinocytesKeratinocytes produce a wide variety of cytokines that have important roles in mediating cutaneous immune responses, inflammation, wound healing, and the growth and development of certain neoplasms. Keratinocytes also produce eicosanoids, prostaglandin (PG) E2, and neuropeptides such as propiomelanocortin and α MSH.In the basal layer of the skin, the innermost stratum, a basal keratinocyte has just divided by mitosis to form a new basal keratinocyte. This new cell starts to divide itself and produces many more keratinocytes.The keratinocytes from the squamous layer are then pushed up through two thin epidermal layers called the stratum granulosum and the stratum lucidum. As these cells move further towards the surface of the skin, they get bigger and flatter and adhere together, and then eventually become dehydrated and die.

B.
Acid rain breaking down the surface of a rock.
C.
A glacier weathering a mountainside.
D.
Wind depositing sand to build up sand dunes.

Answers

Answer:

D

Explanation:

because wind is depositing sand to build

Wind depositing sand to build up sand dunes best illustrates a natural process acting as a constructive force. Therefore, the correct option is D.

What is a constructive force?

Constructive forces are the forces that are responsible for the formation of new landforms on the surface of the earth, such as deposition, earthquake, volcanoes etc.

Wind depositing sand to build up sand dunes is the natural process depicting the constructive force  because sand dunes are formed by constructive forces that add sediment to an area, in this case, wind depositing sand.

Option A is incorrect because river erosion is a destructive force that wears away soil and rock, rather than building it up. Option B and option C are also destructive forces. Therefore, the correct option is D.

Answers

Answer:

The correct answer is - prophase I

Explanation:

Crossing over or recombination is the event that takes place during the pachytene stage of Prophase I of Meiosis I. During this event, the exchange in genetic material between non-sister chromatids of homologous chromosomes results in the recombination of the genetic material or recombinant chromosome.

Prophase I is the first stage which is characterized by the condensation of the chromosome and form tetrad and appeared to be X like structure in the cell and followed by the crossing over or genetic exchange of homologous chromosomes.

Answers

Answer:

They are pollinators.

Explanation:

Bees are vital to our ecosystem because they are pollinators and due to this pollination, these bees are responsible for the presence of trees, shrubs and other small plants etc. if bees were to disappear from ecosystem Earth then the whole world is adversely affected because trees can't produces fruits and seeds so after sometime animals die due to unavailability of food. Human activities are responsible for the death of these bees because human activities causes pollution which is not good for bees. We have to make a safe place for bees and grow as many flowers as you can in order to increase their population.

Explanation:

Two populations of birds with somewhat different coloration live on two different islands. When birds from the two populations are brought together, they produce young whose appearance is intermediate between the two parents. These offspring can successfully breed with each other or with birds from either parent population, and all offspring of these pairings appear intermediate to various degrees. According to the biological species concept, the two populations on different islands ___.

Answers

Answer:

represent a single species

Explanation:

According to the biological species concept, a species can be defined as a group of organisms that can potentially interbreed (i.e., mate) in order to produce viable and fertile offspring. Based on this concept, the cohesion forces that maintain the integrity of the species as a single group are 1-interbreeding between its members and 2-reproductive isolation mechanisms that prevent successful mating between organisms from different species. In this case, both bird populations represent the same species because when individuals of these populations are brought together they can interbreed to produce viable and fertile offspring.

what is the difference between a disease and an infection​

Answers

Answer:

disease occur when the cells in your body are damaged and multiplies and infection occurs when bacteria is there.

hopefully this helps.

A disease is any condition in which the body is not working properly. Many diseases are quite trivial and clear up quickly without treatment, for example a cold. Some are severe, even life-threatening, such as many, not all, types of cancer.

Infections are one particular type of disease. An infection is a disease caused by a living organism (a germ), which is living in the body of the affected person. The germ may be a bacterium, virus, fungus or parasite.

Like all diseases, infections vary in how severe they and whether they need treatment. The common cold is a virus infection; colds are not dangerous unless a person is already sick or very weak. Tuberculosis is a bacterial infection, which can be very difficult to treat and causes many deaths every year.

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

Answers

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.
