Answer:
This question appears incomplete
Explanation:
This question appears incomplete. However, one similar substance that, if missing, many cycles (particularly the two cycles/processes provided in the question) will not exist/proceed is the sun/sunlight.
In the water cycle for instance, if there is no sun/sunlight, there will be no heat to allow for evaporation of water from the water-body (ocean, sea, stream or lake) hence there will be no cloud of water droplets in the atmosphere. The implication of this is that, the first process of the water cycle will not proceed, hence the cycle will not exist.
During photosynthesis, carbondioxide reacts with water in the presence of sun/sunlight to produce glucose and oxygen. The absence of sun in this reaction will not lead to the production of glucose which is the useful product of photosynthesis for plant.
From the explanation above, it can be deduced that the absence of the sun/sunlight will prevent the two cycles from existing.

Answer:
C.) B+I-D-E
Explanation:
The correct formula for population growth is the individuals added to the population via birth or immigration, minus the individuals removed from the population via death or emmigration. Therefore the answer is (B+I)-(D+E), or B+I-D-E
A layer of cells called the endodermis surrounds the stele. Xylem is found towards the center of the stele and phloem towards the outside of the stele. 18) How does this compare to their arrangement in the stem? 19) The meristematic region is protected in the root by the presence of a root cap. How is the meristematic region protected in the stem tip? 20) In which of these regions would you expect to find the specialized cells of vascular tissue? 21) In which of these regions are the cells genetically identical? 22) Why?
Answer:
Epidermis layer is responsible for the protection of meristematic region.
Explanation:
Meristematic region is protected in the stem tip by epidermis which consist of dead layer of cells. Epidermis is the outer layer of stems, leaves, flowers and fruits which is responsible for the protection of inner part from damage. Vascular bundle such as phloem present near the boundary of the stem while the xylem is present in the inside of the stem. In the inside layer of the stem, all the xylem cells are genetically identical while the layer that is present at the edge of the stem is phloem in which all the cells are genetically identical to each other.

A couple has just learned their neonate is diagnosed with osteogenesis imperfecta, and they
ask, "What caused our child to get this disease?" What should the health care provider teach
the couple about their neonate's condition?
Answer:
osteogenesis imperfecta is an inherited genetic disease that mainly affects the bones.
Explanation:
Osteogenesis imperfecta is an inherited genetic disease associated with alterations in collagen synthesis, which have been shown to increase the risk to suffer bone fractures. This genetic disorder is characterized by different health problems including, among others, fragile bones, reduced skeletal mass, skin hyperlaxity, malformations in the central nervous system, etc. Clinically, osteogenesis imperfecta must be managed by an interdisciplinary medical team, since patients may present a clinical picture ranging from mild to lethal. In the first place, it is imperative to provide health care to avoid fractures, exercises to maintain muscle mass, exercise to improve motor skills, skincare by specialized dermatologists, etc.
The disease 'osteogenesis imperfecta' is caused by the neonate inheriting it
from either of the parent because it's a genetic disorder. The health care
provider should teach the parent about how to prevent the effect of having
such disease such as bone fractures.
Osteogenesis imperfecta is a genetic disorder inherited by offspring from
their parent. The disease involves individuals having very brittle bones which are easily broken. The nurse should teach the parent to adopt bone strengthening steps such as adequate calcium intake and physiotherapy.

If bacteria transformed with a recombinant pUC18 plasmid produce white colonies when grown on plates containing ampicillin and Xgal, which of the following is least likely?
a. They produce β-lactamase that provides resistance to ampicillin.
b. They carry a vector that contains a DNA fragment inserted into the multiple cloning site.
c. They produce functional β-galactosidase that cleaves X-gal.
d. They carry a vector with a lacZ gene that has been disrupted and rendered nonfunctional.
e. They carry a vector with the bla gene used as the selectable marker.
Answer:
c. They produce functional β-galactosidase that cleaves X-gal.
Explanation:
β-galactosidase is an enzyme capable of catalyzing the enzymatic hydrolysis of β-galactosides into monosaccharides by hydrolyzing the β-glycosidic bond. On the other hand, X-gal is an analog of lactose composed of galactose, which is widely used in laboratories for the detection of β-galactosidase. In the presence of β-galactosidase, X-gal is hydrolyzed by cleaving its β-glycosidic bond, thereby confirming the presence of β-galactosidase.

After entering a dark room, you turn on a light switch, but the light does not come on. Please suggest three different hypothesis that might explain your observation. Please also note how you might test these hypotheses and describe what observation(s) may lead you to conclude that one of the hypothesis is correct.
Answer:
First hypothesis; may be the power is cut. ( no power supply) Second hypothesis; may be the light switch is defective ( wall switch not working )Third hypothesis; maybe the bulb is burnout ( light bulb may not be working )Explanation:
The three possible hypothesis for light not to turn on immediately after one on the switch are;
First hypothesis; may be the power is cut. ( no power supply) Second hypothesis; may be the light switch is defective ( wall switch not working )Third hypothesis; maybe the bulb is burnout ( light bulb may not be working )We test the first hypothesis, how?
We check if other electronics connected to the same sources of power supply as the bulb is working. If the electronics are not working, then the first hypothesis is correct but if they are working then the hypothesis fails and we move on to test the next hypothesis.
To test for the second hypothesis as the first hypothesis fails, we remove the bulb and fix it into another socket which has a working switch. If the bulb comes on then the second hypothesis is correct but if the bulb does not turn on then the hypothesis fails so we move on to test the third hypothesis.
As the bulb fails to turn on in our initial socket and a second bulb is fixed in that same socket and it came on, then the third hypothesis is correct.
The three hypotheses we can derive from entering a dark room, turning on a
light switch,and the light not coming on include
There may be no power source at that momentThe bulb may be faultyThe switch may be faultyA power source helps to provide energy to power up an appliance and where it is absent, the bulb won't light up.
A defect in the switch and bulb may also hinder the light from coming on as
the switch controls electric current flow while the bulb produces the light.

Myristoyl-CoA is a saturated fatty acid with 14 carbons attached to coenzyme A. How many molecules of ATP would be generated from the complete oxidation of a single molecule of myristoyl-CoA
Answer:
Total ATP molecules produced = 94 molecules of ATP
Explanation:
Myristoyl-CoA, is a saturated fatty acid with 14 carbons which has been activated for oxidation by attachment to coenzyme A. When it has undergone complete oxidation, it will yield 7 acetyl-CoA molecules and 6 FADH₂ and 6 NADH molecules each.
Each of the 7 acetyl-CoA molecules obtained from its initial oxidation enters into the citric acid cycle and is completely oxidized to yield further ATP and FADH₂ and NADH molecules.
The overall yield of ATP from the various enzymatic steps is shown below:
Acyl-CoA dehydrodenase = 6 FADH₂
β-Hydroxyacyl-CoA dehydrogenase = 6 NADH
Isocitrate dehydrogenase = 7 NADH
α-Ketoglutarate dehydrogenase = 7 NADH
Succinyl-CoA synthase = 7 ATP (from substrate-level phosphorylation)
Succinate dehydrogenase = 7 FADH₂
Malate dehydrogenase = 7 NADH
Note: 1 FADH2 molecule yields 1.5 ATP; 1 NADH molecule yields 2.5 ATP molecules. Therefore,
Total ATP from FADH₂ molecules = 13 * 1.5 = 19.5
Total NADH molecules = 27 * 2.5 = 67.5
Total ATP molecules produced = 19.5 + 67.5 + 7 = 94
Total ATP molecules produced = 94 molecules of ATP

Food microbiologists are scientists who have a background in both microbiology and food science. They focus on how microbes grow, cause disease, and how they can be identified from food. Their work is of importance to the food industry as it relates to the production, preservation, and spoilage of food; and it is of importance to public health and regulatory agencies due to the many diseases that are related to food intake and consumption. Food microbiologists can have varying backgrounds, including training in veterinary medicine. This scenario is about a food microbiologist who works as a food safety inspector who pays a visit to a cheese manufacturing plant and makes some interesting discoveries!
Part A-Understanding the Role of Microbes in Fermentation The Midwest is known for its contribution to the dairy industry Fermented dairy products include milk, yogurt, and cheese. The fermentation process relies on lactic acid bacteria and pasteurization. Fermentation can vary based on what food is being produced, the type of bacteria used to produce lactic acid, and the time and temperature of pasteurization. It is important to the manufacturer to produce a product that won't spoil before it is packaged and sold and that won't result in disease for those who ingest and enjoy it. Julie, a food inspector for a local Michigan health department is going to a nearby cheese plant for a biannual inspection. When she gets there, she will take a tour of the plant and allow the operators to describe what makes their cheese so special. She will use what she understands about fermentation to inquire about their production practices Please sort the following statements as being true or false regarding fermentation and its role in food production. Please recall the role that microorganisms can play in the production of foods.

Intrinsic factor A. increases gastric motility. B. causes the release of stomach acid. C. facilitates the absorption of vitamin B12. D. protects the stomach lining from the effects of stomach acid. E. stimulates the synthesis of DNA.
Answer:
C. facilitates the absorption of vitamin B12.
Explanation:
The Intrinsic factor is a substance that is produced by the stomach and it has the important function of producing vitamin B12 which is necessary for life. Vitamin B12 is used in the production of mature red blood cells. It also improves the function of the nervous system. The production of this intrinsic factor is a very vital role of the stomach because, in the absence of a stomach, for example, in the case of a gastrectomy, a person can only survive if he is given injections of Vitamin B12.
The stomach also serves as a holding center for food and eventually delivers the food to the small intestine and the duodenum.
