A disorder that is a result of shortage of proteins in children is Kwashiorkor

Explanation:

Kwashiorkor is a severe form of malnutrition. It's most common in some developing regions where babies and children do not get enough protein or other essential nutrients in their diet. The main sign of kwashiorkor is too much fluid in the body's tissues, which causes swelling under the skin (oedema). (Source: Kwashiorkor - NHS)

Hopefully this helps.

Kwashiorkor is a serious condition that can happen when a person does not consume enough protein. Severe protein deficiency can lead to fluid retention, which can make the stomach look bloated.

Kwashiorkor is most common in children, especially if they do not have access to adequate nutrition soon after they stop breastfeeding. If a child experiences kwashiorkor, they need immediate medical attention.

Other terms for kwashiorkor include:

protein malnutrition

malignant malnutrition

protein-calorie malnutrition

Explanation: But to answer the "Earth warming up" question, I'd have to say that for over millions of years, Earth's climate has warmed up and cooled down many times. However, today the planet is warming much faster than it has over human history. Global air temperatures near Earth's surface have gone up about 2 degrees Fahrenheit in the last century. However, other evidence suggests that the period of 2,000 to 3,000 million years ago was generally colder and more glaciated than the last 500 million years.

So, yes I do believe that the Earth is warming up but not to explode.

Answer:

Agricultural fertilizers are one of the main human causes of eutrophication. Fertilizers, used in farming to make soil more fertile, contain nitrogen and phosphorus. The use, or overuse, of fertilizers can cause these nutrients to runoff of the farmer's field and enter waterways. Eutrophication can have serious effects, like algal blooms that block light from getting into the water and harm the plants and animals that need it. If there's enough overgrowth of algae, it can prevent oxygen from getting into the water, making it hypoxic and creating a dead zone where no organisms can survive.

The following is a list of methods that can be used to control eutrophication:

planting vegetation along streambeds to slow erosion and absorb nutrients.

controlling application amount and timing of fertilizer.

controlling runoff from feedlots.

The best, easiest, and most efficient way to prevent eutrophication is by preventing excess nutrients from reaching water bodies. This can be done in a number of ways, the simplest of which is just being aware of the chemicals and fertilizers that we are using.

Answer:

Ballon 2

Explanation:

sorry pero hindi ako sigurado

Answer:

balloon 2 is less thermal energy because this balloon is high temperature than balloon 1

Answer:

Explanation:

Given that:

The dilution rate D = 0.28 h⁻¹

The concentration of lactose in the feed [tex]S_o = 2.0 \ g/L[/tex]

The effluent S = 0.10 g/L

Also;

[tex]Y_{X/S} = 0.45 g\ X/g \ S , \\ \\ Y_{X/O2 }= 0.25 g \ X/g \ O2, \\ \\[/tex]

Saturation C* = 8 mg/l

To calculate the steady-state biomass, we use the formula:

[tex]X = Y_{X/S}(S_o-S_e) \\ \\ X = 0.45(2.0 -0.10) \ g/L \\ \\ X= 0.45 (1.9) \ g/L \\ \\ X = 0.855\ g/L \\ \\ X = 855 \ mg/L[/tex]

The biomass is 0.855 g/L

For a steady-state condition, the oxygen uptake rate can be illustrated by using the formula:

[tex]q_{o_2}X =\dfrac{\mu_X}{Y_{X/O_2}}[/tex]

where;

[tex]\mu =[/tex] dilution rate (D)

Thus, the steady-state can be expressed as:

[tex]q_{o_2}X =\dfrac{D}{Y_{X/O_2}}[/tex]

[tex]q_{o_2}X =\dfrac{0.28}{0.25}[/tex]

[tex]q_{o_2}X =1.12 \ h^{-1}[/tex]

The specific rate of oxygen consumption [tex]q_{o_2}X =1.12 \ h^{-1}[/tex]

b)

In the fermentation medium, if the desired DO concentration [tex]C_L[/tex] = 2 mg/L

Here, the oxygen transfer is regarded as the rate-limiting step.

As such, the oxygen transfer rate(OTR) is equivalent to the oxygen uptake rate.

In this scenario, let's determine the oxygen transfer coefficient [tex](K_{La})[/tex] by using the formula:

[tex]OTR = K_{La}(C^* - C_L)[/tex]

where;

[tex]K_{La}[/tex]= coefficient of oxygen transfer

C* = saturation

Since [tex]OTR = q_{O_2}X[/tex]

[tex]q_{o2}X = K_{La}(C^*-C_L) \\\\ (1.12 )(855) = K_{La}(8-2) \\ \\ 957.6 = K_La (6) \\ \\ K_{La}= \dfrac{957.6}{6} \\ \\ K_{La} = 159.6 \ h^{-1}[/tex]

Thus, the oxygen transfer coefficient [tex]K_{La}[/tex] = 159.6 h⁻¹

Answer:

Explanation:

After amylase act on carbohydrates, the chyme pass through the oesophagus down to the dudoneum in the small intestine. Amylase also continue to break it down into disacharrides and enzymes like maltase, sucrase and lactase are released to further break it down into maltose, sucrose, and lactose then finally glucose, a way it can be absorbed easily by the epithelial walls.

The digestion of lipids and protein begin in the dudoneum of small intestine.

Trypsin act on protein and break it down to peptides. Peptidase is then released and break it to single chain peptides bond. In the small intestine, dipeptidases break it down into amino acids easily absorbed by the epithelial walls.

The bile in the gall bladder produce enzyme called lipases which breakdown lipids and make it to undergo emulsification.

Answer:

So others don't get confused, the answer would be Measure the circumference of each balloon

Explanation:

The student will utilize the following factors to make quantitative observations of the carbon dioxide collected in the balloons which are   describing the shape of each balloon, the relative size of each balloon and measuring the circumference of each balloon.

Yeast is a type of fungus that undergo fermentation, where it converts sugar into energy and carbon dioxide is produced during the process as a byproduct.

When sugar in different amounts is provided to the yeast, the carbon dioxide concentration will also differ accordingly. More fermentation leads to more sugar production which leads to increase in level of carbon dioxide.

The shape of the balloon determines the volume of carbon dioxide produced. The amount of carbon dioxide produced in each container is compared by the relative size of each balloon and measuring the balloon circumference will help to calculate the volume of gas.

Therefore, describing the shape of each balloon, the relative size of each balloon, measuring the circumference of each balloon are very important factors to determine the carbon dioxide collected in balloons.

Answer: It shows the distribution of the population with respect to a characteristic, quantitative and continuous, such as the weight or height of a population. It is used to determine the degree of homogeneity of the values studied, or to see the degree of variability, and therefore, the dispersion of all the values taken by the parts.

Explanation:

A histogram is a graphical representation of a variable using bars. In such a bar, its area is proportional to the frequency of the values represented. Thus, it shows the distribution of the population, or of the sample, with respect to a characteristic, quantitative and continuous, such as the weight or height of a population. It is used to determine the degree of homogeneity of the values studied, or to see the degree of variability, and therefore, the dispersion of all the values taken by the parts.

In order to construct a histogram first we need to have a frequency table with all the information. On the abscissa axis (horizontal axis) the intervals are placed from smallest to largest.  On the ordinate axis (vertical axis), the absolute frequencies of each of the intervals are represented.  Then, the rectangular bars of equal width are drawn, and the height represents the absolute frequency. All bars touch the bars next to each other, unless an interval has zero frequency (the height of the bar will also be zero).

Thus, histograms are used to describe populations since they represent a variable and in what proportion of the population it is found.

The population can be given as the number of people living in a specific area. The histogram represents the population, with frequency as the function of the area.

A histogram is the graphical representation of the data in the form of bars. The population is given as the number of people in an area.

The population in the area is termed as frequency. The bar graph represents the frequency of population as the function of the area and thereby helps in the determination of the population.

Answer:

Metabolic pathways in monarch butterflies are as follows:

Explanation:

They convert sugar which they obtain from nectar into fats that they store as source of energy. Monarch have a little layer of fatty tissues which aid in conversion of Sugar in to fat.

They consume the stored fat during reproduction. A lot of fat is eventually converted to eggs and some of it is used to provide energy just to sustain the reproductive butterflies.

During winter season, when their metabolic is low they consume energy by converting stored fat into sugar called Trehalose.  The conversion of fat also releases little water which help them to survive during winter.

1) Glycolysis:

2. Kreb's Cycle:

The acetyl-CoA formed enters into the Kreb's cycle by condensing with oxaloacetate. In Kreb's cycle acetyl-CoA is completely oxidised to give carbon dioxide in eight enzymatic reactions. During Kreb's cycle NADH, FADH2 and one molecule of GTP is produced and oxaloacetate is regenerated to continue the cycle.

3. Oxidative Phosphorylation:

The NADH produced in the glycolysis and Krebs cycle and FADH2 produced during Krebs cycle are now oxidised to generate proton gradient across the inner mitochondrial membrane. This gradient is generated when the electrons from the reduced NADH and FADH2 are transported in the electron transport chain(ETC), and are finally accepted by the oxygen.

When the electrons are picked up by the complexes of the ETC they pick protons from the matrix. When the electrons are transferred to next complex the protons are transferred to the inter-membrane space. In this way a proton gradient is generated across the innner membrane of the mitochondria.

This proton gradient is used by the complex V of the ETC. This complex is the enzyme ATP Synthase. This enzyme complex is located in the inner mitochondrial membrane. When the protons flow back from the inter-membrane space into the matrix along the concentration gradient , they move through the channel in the ATP Synthase Complex. When these protons flow through this complex it catalyzes the phosphorylation of ADP to give ATP, the energy currency.

The fructose component of the sucrose is first converted into glycogen and then broken down to give glucose-1-phosphate, which enters into glycolysis.

Sucrose cannot enter the pathway of glycolysis as such. It is first hydrolysed to glucose and fructose as described above along with the path way.
