Answer:
The age difference between the oldest and the youngest is 48.
Explanation:
Given the following data;
The ratio of the ages of Kisii (K) and Esinam (E) is 3:5.
The ratio of the ages of Esinam (E) and Larry (L) is 3:5.
The sum of the ages of all three is 147.
Since the age of Esinam is common in both ratios, we find the lowest common multiple (LCM);
LCM of 3,5 = 15.
Hence, the ratio of the three ages is now;
K:E:L = 9:15:25
Let their ages be denoted by x;
\(K:E:L = 9x:15x:25x\)
The sum of all three ages is;
9x + 15x + 25x = 147
49x = 147
x = 147/49
x = 3.
To find the age difference between the oldest and the youngest;
The oldest is Esinam = 25x
The youngest is Kisii = 9x
Therefore, 25x - 9x = 16x
Substituting the value of x, we have;
x = 3; 16x = 16(3) = 48.
The age difference between the oldest and the youngest is 48.

Problem B: Diabetes is a disease affecting the insulin producing glands of the pancreas. If there is not enough insulin being produced by these cells, the amount of glucose in the blood will remain high.
Answers
Diabetes is a disease that occurs when the pancreas doesn't produce enough insulin, resulting in high blood glucose levels.
Diabetes is a medical condition that impacts the insulin-producing glands of the pancreas. The pancreas plays a crucial role in regulating blood glucose levels by producing insulin. Insulin allows glucose to enter cells, providing them with energy. In diabetes, insufficient insulin production leads to elevated levels of glucose in the bloodstream, a condition known as hyperglycemia.Without enough insulin, glucose cannot be effectively transported into cells, resulting in its accumulation in the bloodstream. This leads to persistent high blood glucose levels, which can have various detrimental effects on the body over time. Complications of uncontrolled diabetes may include damage to blood vessels, nerves, and organs.Managing diabetes typically involves interventions like insulin therapy, medication, dietary adjustments, and lifestyle modifications to regulate blood glucose levels and minimize associated complications. Regular monitoring and appropriate management are crucial to maintaining optimal blood glucose control and overall well-being for individuals with diabetes.For more such questions on Diabetes:

The human and cow genes are very similar, but not identical. There will be some differences in the codons (mRNA) that code for certain amino acids. It is difficult to determine exactly how many codons are the same without knowing the specific genes being compared. Similarly, the number of identical amino acids in the sequence will depend on the specific genes being compared. Yes, it is possible for two humans or two cows to have differences in their DNA sequences for insulin, yet still make the exact same insulin proteins. This is because the genetic code is degenerate, meaning that multiple codons can code for the same amino acid. Additionally, there are often variations in non-coding regions of DNA that do not affect the final protein product. The six codons that can code for the amino acid leucine are: UUA, UUG, CUU, CUC, CUA, and CUG.What is the gene about?In terms of question 5, A. The mutant DNA codes for the amino acid tyrosine (Y), while the normal DNA codes for a stop codon. The person with this mutation will not be diabetic because the protein product will be truncated and not functional.
B. The mutant DNA still codes for the amino acid leucine (L), although it is coded for by a different codon. Depending on the exact location of the mutation, this person may or may not be diabetic. If the mutation occurs in a critical region of the insulin gene that affects its function, the person may be diabetic. However, if the mutation occurs in a non-critical region, the person may still be able to produce functional insulin.
Therefore, Based on the amino acid sequences, the human and chimpanzee are the most closely related organisms. The two sequences are almost identical, differing only by a single amino acid at position 2. The pig and cricket sequences are much more different from the human and chimpanzee sequences, differing at multiple positions.

Answers
Answer:
70 km/hr
Explanation:
Distance between town A and B = 210 km
Della's speed = 60 km/hr
Time taken by Della = distance / speed
Time taken by Della = 210 km / 60km/ hr
Time taken by Della = 3.5 hours
Since Nick left half an hour later Than Della ;
Then, Nick's travel time = 3.5 - 0.5 = 3 hours
Nick's average speed = Distance /time
Nick's average speed = 210 / 3 = 70km/hr

A peptide bond is a type of chemical connection between two amino acids.
The amino group of one amino acid is joined to the carboxyl group of the second amino acid during a condensation reaction, which also eliminates a water molecule. The two amino acids are held together in a certain order by the next covalent bond.
A peptide bond's main job is to connect amino acids to create polypeptide chains. The genetic code dictates the order of the amino acids in the polypeptide chain, and the precise arrangement defines the protein's function.

The student's hypothesis is incorrect; compacted-soil flood control barriers lasted longer than I-wall barriers in the investigation.
Based on the data collected in the student's investigation, the evaluation of the hypothesis shows it to be incorrect.

However, the results showed that I-wall barriers broke after an average of 8 liters of water were added, while compacted-soil barriers withstood an average of 15 liters.
This indicates that compacted-soil flood control barriers are more effective in lasting longer under the tested conditions compared to I-wall style barriers.

C) Conditions were not kept the same
D) The experiment was not reproduced
Answers
Answer:
B) Subjects were not similar
The errors in this experiment are: subjects were not similar and conditions were not kept the same. Hence the correct options are B and C.
Subjects were not similar: The gardener used two different types of plants, beans, and peppers, to test the effectiveness of E-Z fertiliser. Beans and peppers have different growth requirements, nutritional needs, and environmental preferences. By using different types of plants as subjects, the experiment introduces variability and makes it difficult to attribute the outcome solely to the fertiliser.
Conditions were not kept the same: The gardener applied E-Z fertiliser to the bean plants but did not provide any fertiliser to the pepper plants. This difference in treatment introduces a significant confounding factor, making it impossible to isolate the effect of the fertiliser on the bean plants' poor performance.

Here, the postsynaptic neuron has an RMP of -70mV and a typical threshold of -55mV. When neuron X is stimulated, it depolarizes by 0.5 mV.
When X and Y are stimulated simultaneously, the postsynaptic neuron depolarizes by 1 mV, which is sub-threshold (below -55mV).

In a population the homozygous dominant individual make up 70% of the population while heterozygous ones made up 21% and recessive made up 9%. What are the frequencies of the A and a alleles?
Answers
There are two alleles in a population that influence a specific attribute. Using the letters "A" for the dominant allele and "a" for the recessive allele. A allele frequency is 0.7, whereas frequency of allele is 0.09.
The frequency of the A allele is 0.7, or 70%, since homozygous dominant (AA) genotypes account for 70% of the population. Similarly, since homozygous recessive (aa) alleles make up 9% of the population, we can infer that the frequency of the recessive allele, a, is 0.09, or 9%.
The formula 2pq = frequency of heterozygotes, where p is the frequency of the A allele and q is the frequency of the an allele, can be used to determine the frequency of the heterozygous genotype (Aa).
We know that the frequency of heterozygotes is 0.21, or 21%.
Plugging in the known values:
2 * 0.7 * q = 0.21
Solving for q:
q = 0.15
So, the frequency of the A allele is 0.7, and the frequency of the a allele is 0.09.
