How do the baby's respiration and circulation change when the baby is born? O A. The baby's blood has oxygen for the first time. B. The baby now breathes oxygen instead of carbon dioxide. C. It no longer depends on the mother for oxygen. D. The circulatory system pumps blood for the first time.
During pregnancy, the baby grows and depends on mother for food, nutrition, oxygen, etc. the baby's respiration and circulation change when the baby is born as it no longer depends on the mother for oxygen, i.e., option C.
What is the way of oxygen transport from mother to child during pregnancy?As the fetus is connected by the umbilical cord to the placenta, the organ will develops and implants in the womb during pregnancy.
Through umbilical cord having blood vessels, the baby will receives all the necessary nutrition, oxygen, and life support from the mother with the help of the placenta.
As the baby comes out, it will no longer depend on the mother for oxygen.
Thus, the correct option is C.

Research the effect of insulin on blood sugar after a meal. You may use outside sources. Select the correct statement. Insulin has no effect on blood sugar. Insulin increases blood sugar. Insulin reduces blood sugar.
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.
A student is sitting in class drinking a 16.9 fl oz bottle of Arizona tea (the size that you get from the deli). The student isn’t doing any activity, so the student’s body doesn’t need the sugar right away. What happens to all the sugar?
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.

APC is a tumor suppressor and acts in the Wnt signaling pathway to prevent the TCF complex from turning on Wnt-responsive genes. Mice that lack the gene encoding TCF4 do not have the ability to maintain the pool of proliferating gut stem cells needed to renew the gut lining. What do you predict will happen in mice that lack the APC gene
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.

problems might be caused by sickle-shaped red blood cells?
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.

Which role do ultrafine particles play in dirty air?
They contribute to less than 13,000 premature deaths a year.
They can worsen symptoms for people with breathing difficulties.
They are easily removed from the air when people see them floating.
They are constantly filtered by the nose, which prevents lung absorption
Answer:
B
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).
What are ultrafine particles?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).

How is composting solid waste similar to and different from burying it in a landfill?
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.

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
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

Select an organism of your interest! Research to see if that organism undergoes asexual or sexual reproduction. Describe why that type of reproduction is advantageous for your organism.
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.
