Answer: hello your question is in complete  below is the complete question

A fiber reinforced composite contains e-glass fibers in an epoxy matrix. E for the glass is 72 GPA, E for the epoxy is 2.4 GPa. Find the elastic modulus of a composite that contains 5% fibers in the longitudinal direction, Ecl = ViEi + EmVm? (note Vi + Vm= 1.) O 5.88 GPa O 5.66 GPa O 2.52 GPa O 6.74 GPa

answer : 5.88 GPa

Explanation:

Fiber reinforced composite containing e-glass fibers

E for the glass ( Ei ) = 72 GPa

E for the epoxy ( Em ) = 2.4 GPa

Determine the Elastic modulus of a composite containing 5% fibers

percentage of glass = 5% = Vi = 0.05

∴ percentage of epoxy = 95% ; Vm = 0.95

using the relation included in the question

Ecl = Ei Vi + Em Vm

    = ( 72 * 0.05 ) + ( 2.4 * 0.95 )

    =  3.6 + 2.28  = 5.88 GPa

Answer:

The sugar is stored as glycogen in the students body

Explanation:

The food we consume contains sugar molecules (carbohydrate) that is broken down via respiration to synthesize energy (ATP). However, the sugar is not always utilized at once as the excess is stored as a carbohydrate called GLYCOGEN in our liver cells or muscle.

According to this question, a student is sitting in class drinking a 16.9 fl oz bottle of Arizona tea. The student, however, is not doing any activity and so his/her body does not need the sugar right away. This means that the body will store the sugar as GLYCOGEN until it is needed.

Answer:

Many fungi and plants reproduce asexually. Some plants have specialized structures for reproduction via fragmentation.

Explanation:

This allows them to adjust to conditions in the environment. They can spread quickly through asexual reproduction when conditions are stable. They can increase their genetic variation through sexual reproduction when conditions are changing and variation may help them survive.

Reproduction is a method by which the genetic material from the parent is transferred to offspring and in this way the character and traits are passed from generations.

I will select plants for my research purpose.

Plants are species that reproduce sexually. They have male and female organs that produce cells for reproductions. They sexually reproduce through the process of pollination.

This method of reproduction helps in genetic variation and in forming recombinant species that are more variant.

This variation helps the plant species to survive better compared to less competent species.

Sexual reproduction is beneficial for plants as it increases varieties and helps plants in fighting against a common population disease.

Answer:

Basically, this means that because municipal solid waste that is buried in a landfill does not receive oxygen, it will produce methane. A compost pile, on the other hand, undergoes aerobic decomposition. ... But, if a compost pile is being taken care of properly, it will produce far less methane than a landfill.

Answer:

Insulin reduces blood sugar.

Explanation:

Insulin is an hormone produced naturally in the pancreas organ of the body. Insulin is majorly involved in digestion where it helps in the absorption process. Insulin aids the absorption of glucose by cells.

When a meal is eaten, the food digests and breaks down into GLUCOSE, which enters into the blood stream via the small intestine. Insulin ensures that the sugar (glucose) content in the blood REDUCES by moving glucose into cells for respiration (energy production) and storing the excess glucose as glycogen in the liver cells.

Answer: Plant cell needs cell wall whereas animal cell do not because the plants need rigid structure so that they can grow up and out

Explanation: All cells have cell membranes, and the membranes are flexible. So animal cells can have various shapes, but plant cells only have the shapes of their cell walls.

Answer:

As APC is indicated as a tumor suppressor, lack of APC would lead to tumor development in the mutated mice.

Explanation:

The wnt signaling pathway plays an important role in controlling stem cell proliferation. Stem cells are present in the gut and other locations where they are required to be replenished after short intervals. In the gut, the gut epithelial is exposed to a very tough environment i.e. digestive acids. Thus it is replenished where the new stem cells originate from underlying stem cells.

Axin binding is the major component of this process. However, the unaffected axin leads to binding with a component termed TCF. TCF4 genes include cell cycle factors (such as myc) that encourage cell regeneration.

When the ligand is absent and APC is present, the axin bound with APC to form a team that directs and controls the cell regeneration.

Thus, if APC is not expressed in a cell, beta-catenin in the axin is available to bind to TCF inducing wnt response element genes that stimulate cell proliferation.

The result in tissue level is an enhanced rate of cell growth which leads to tumor.

Consider the following alleles: X1, X2, X3. The different alleles encode enzymes with slightly different rates of reaction, but are otherwise identical. Consider a population that is sampled for these alleles at two different times. Below are the genotypes for each individual in this population at time 1. For the Time 1 population calculate the allele frequencies and genotype frequencies.(4points)

Answer 1:It should take around 7-10 days before you will be able to see significant growth on the bread. You could see growth as soon as 5 days depending on the type of bread you used. Remember, fresh bread will mold faster than store-bought bread containing preservatives.

Sickle-shaped red blood cells would slow down or cause a blockage (blood clot) to the blood vessels further leading to attacks such as heart attacks.

This is due to the fact; the new shape would simply be unable to pass safely through the small blood vessels to perform its main purpose of transferring oxygen throughout the body.

Answer:

Explanation:

The role the ultrafine particles play in dirty air is that they can worsen symptoms for people with breathing difficulties. The correct answer is b).

The term "ultrafine particles" (UFPs) refers to particles with a dimension of less than micrometers and more than 0.1 micrometres (100 nanometers), also known as nanoscale particles. The majority of the ultrafine particles are found on motorways and are mostly produced by vehicle emissions.  

It has been demonstrated that ultrafine pollution particles may play a crucial role in igniting extra pathways or inflammation, which worsens asthma disease. The ultrafine particles released by motor vehicles and other sources of combustion are covered with an organic chemical coating that can be inhaled.

By oxidizing cells and tissues, these substances create free oxygen radicals that activate the immune system in the lung. For those who have asthma, oxidation exacerbates the allergic inflammation in their lungs.  

Therefore the correct option is b).
