How many water molecules would be needed to break apart a carbohydrate made of 27 glucose monomers? Explain
Carbohydrates are made up of monosaccharides, which are simple sugars such as glucose. When two or more monosaccharides are joined together, they form a disaccharide or a polysaccharide. Polysaccharides are long chains of monosaccharides that are joined together by glycosidic bonds.
In order to break apart a carbohydrate made of 27 glucose monomers, you would need to hydrolyze the glycosidic bonds that hold the monomers together. Hydrolysis is the process of breaking a chemical bond by adding water molecules. For each glycosidic bond that you want to break, you would need to add one water molecule.
Since a carbohydrate made of 27 glucose monomers would have 26 glycosidic bonds (one less than the number of monomers), you would need to add 26 water molecules to break it apart. This is because each water molecule would be used to hydrolyze one of the 26 glycosidic bonds in the carbohydrate.
It's worth noting that the number of water molecules needed to break apart a carbohydrate would depend on the length of the carbohydrate and the type of glycosidic bonds it contains. For example, a carbohydrate with more monomers or with different types of glycosidic bonds might require more water molecules to be hydrolyzed.

O oxigênio é importante um gás na quebra de ligações entre os átomos que formam a glicose para a produção de energia. Por que a presença de ferro no nosso organismo é importante para este processo?
Answer:
It transport oxygen from lungs to the cells.
Explanation:
The presence of iron in our body is very important for this process because iron is responsible for the transportation of oxygen. Hemoglobin is made up of iron that takes oxygen from the lungs to each and every cell. Iron is an essential element for the formation of blood in human body. About 70 percent of body's iron is found in the red blood cells of our blood called hemoglobin and in the muscle cells called myoglobin. So we can say that iron is very important for the release of energy in the process of respiration.

Fully explain how multiple hormones are used to control the rate at which glucose is consumed during cellular respiration.
Insulin and glucagon are two hormones secreted by the pancreas involved in glucose metabolism.
insulin is secreted by the beta cells of the islets of Langerhans and contributes to lowering blood sugar levels. In this case, insulin causes the body's cells to absorb blood glucose in order to reduce it.
while glucagon is secreted by the alpha cells of the islets of Langerhans and contributes to the increase in blood glucose concentration. In this case, glucagon stimulates the liver to release glucose into the bloodstream.
since insulin is secreted when there is a lot of glucose in the blood and glucagon when there is little sugar in the blood, these two mechanisms are opposite and regulate each other, to achieve homeostasis or balance in the organism.
All eukaryotic cells have mitochondria, but only plants and some photosynthetic protists have chloroplasts.
Since plants and photosynthetic protists do not have the machinery for being heterotroph but they can make their own food in the presence of chloroplast, this is the reason why they possess chloroplast. Animals cells on the other hand cannot perform photosynthesis and hence do not possess chloroplast.
Heterotroph is one of the types of mode of nutrition. In this the organism obtains their food from some other organism that can either be plant or another animal. The example of heterotrophs are all the animals and humans.
Photosynthesis is the process of synthesizing food by capturing the sunlight energy and releasing oxygen as the by-product.

Problem 4 (15 points) An ideal single-phase transformer is rated at 20 kVA, 960/240 V. The transformer is fully loaded by an inductive load of 0.90 power factor lagging. Compute the following: a) The real power delivered to the load. b) The magnitude of the load current. c) The magnitude of the primary-side current. d) The power supplied at the primary side of the transformer if the transformer is 97% efficient.
The magnitude of the load current is 83.33 Amperes.
To solve this problem, we'll use the following formulas and concepts:
a) Real Power (P) = Apparent Power (S) x Power Factor (PF)
b) Load Current (I_load) = Apparent Power (S) / Voltage (V_load)
c) Primary-Side Current (I_primary) = Load Current (I_load) x Turns Ratio (N)
d) Power Supplied at the Primary Side (P_primary) = Power Supplied at the Load Side (P_load) / Transformer Efficiency
Given data:
Transformer Rating: 20 kVA (kilo-volt-ampere) = 20,000 VA
Voltage on the Load Side: 240 V
Voltage on the Primary Side: 960 V
Power Factor (lagging): 0.90
Transformer Efficiency: 97%
Let's calculate the values step by step:
a) Real Power delivered to the load:
Apparent Power (S) = Transformer Rating = 20,000 VA
Power Factor (PF) = 0.90
P_load = S x PF
P_load = 20,000 VA x 0.90 = 18,000 W
Therefore, the real power delivered to the load is 18,000 Watts.
b) Magnitude of the load current:
V_load = 240 V
I_load = S / V_load
I_load = 20,000 VA / 240 V ≈ 83.33 A
Therefore, the magnitude of the load current is approximately 83.33 Amperes.
c) Magnitude of the primary-side current:
Turns Ratio (N) = V_primary / V_load
V_primary = 960 V
N = 960 V / 240 V = 4
I_primary = I_load * N
I_primary = 83.33 A x 4 = 333.32 A
Therefore, the magnitude of the primary-side current is approximately 333.32 Amperes.
d) Power supplied at the primary side of the transformer:
P_primary = P_load / Transformer Efficiency
P_load = 18,000 W
Transformer Efficiency = 97% = 0.97
P_primary = 18,000 W / 0.97 ≈ 18,556.70 W
Therefore, the power supplied at the primary side of the transformer is approximately 18,556.70 Watts.

mrs. baskin ran a pcr on the dna of her favorite child don, to find that he was a heterozygote. she calculated the number of repeats for the first and second bands to be 26 and 24, respectively. please help mrs. baskin determine the genotypic frequency of don.
0.6156

0.000123
Probability of being a heterozygote (26-repeat/24-repeat): 2(0.04)(0.04) or 0.0064. To determine the genotypic frequency of Don, we need to calculate the probability of each possible genotype.
Since Don is a heterozygote, he could have inherited the 26-repeat allele from one parent and the 24-repeat allele from the other, or vice versa. The probability of each scenario is equal, so we can calculate the frequency of each genotype by multiplying the probability of inheriting a 26-repeat allele by the probability of inheriting a 24-repeat allele:
- Probability of inheriting a 26-repeat allele: 2/50 or 0.04
- Probability of inheriting a 24-repeat allele: 2/50 or 0.04
Therefore, the genotypic frequency of Don is:
- Probability of being a heterozygote (26-repeat/24-repeat): 2(0.04)(0.04) or 0.0064
So the correct answer is 0.00659 (rounded to the nearest hundredth).
Mrs. Baskin performed a PCR on Don's DNA and discovered he is a heterozygote with 26 and 24 repeats. To determine Don's genotypic frequency, we need to know the frequencies of each allele in the population. Unfortunately, without this information, it is not possible to calculate the genotypic frequency using the given options (0.6156, 0.00659, 0.088, 0.000123).
