What are the bonds found between amino acids in a polypeptide chain

Answers

Answer 1

Answer: Amino acids are joined by peptide bonds in a polypeptide chain. A peptide bond is one in which the molecules of a carboxyl react with the amino group of another molecule. A molecule of water is then formed and release, leaving the functinal groups to bond together and form a polypeptide chain.

Explanation:

Jackson has a credit card with a 15% interest rate. His dad has a credit card with a 5% interest rate. If they both charge $1,000, how much more will Jackson end up paying?A. $500
B. $250
C. $100
D. $125

Answers

"$100" is the one amount among the choices given in the question that Jackson will end up paying more. The correct option among all the options that are given in the question is the third option or option "C". I hope that this is the answer that has basically come to your desired help.

Answer:

Option C, $100

Explanation:

Percent of interest rate on Jackson card $= 15$ %

Percent of interest on Jackson's dad card $= 5$ %

They both take money $= 1000$ $

The interest amount on Jackson card

$= (15)/(100) * 1000\n= 150$ $

The interest amount on Jackson's father card

$= (5)/(100) * 1000\n= 50$ $

Difference between the two interest amount

$= 150-50\n=100$ $

Jackson end up paying $ $100$ more than his father

Correct answer is option C.

When anaerobic respiration occurs in muscle cells, it producescarbon dioxide, water, and energy.
carbon dioxide, ethanol, and energy.
lactic acid and energy.
glucose, oxygen, and energy.

Answers

Technically the best answer would be: Lactic acid and energy

But what actually happens is pyruvate is reduced into lactate and NAD+ is produced to feed back into glycolysis, which then keeps glycolysis going to produce more energy. So it is the best option because none of the others are correct

A population of birds has two feather colours, white and black. Black is dominant over white. If you know that 75% of a population of birds totalling 4520 individuals has the dominant phenotype, determine how many individuals are heterozygous? Please show me the mathematical work to get to the answer!! :)

Answers

Heterozygous means that the bird(s) have the recessive and dominant genotypes. If you have 75% of a population of 4520 birds that have black feathers, that leaves 25% of the population to have white feathers. In order for 25% of the birds to have white feathers, the two genotypes must be Xx and Xx. This leaves the options for the following genotypes when using a punnet square (will add one at the bottom): XX, Xx, Xx, xx. This gives you the percentage of heterozygous birds, which is 50%. If you take 50% of 4520, (4520 x 1/2 = 2,260) that is the number of heterozygous birds in the population.
Final Answer: 2,260 birds are heterozygous.
Punnet Square:
X x
X XX Xx
x Xx xx

Final answer:

To determine the number of heterozygous individuals in a population of birds with black and white feather colors, we can use principles of Mendelian genetics and the Hardy-Weinberg equation. By calculating the frequency of the recessive allele and applying the equation 2pq, we can find the number of heterozygous individuals. In this case, the population contains 2260 heterozygous individuals.

Explanation:

To determine the number of individuals that are heterozygous, we need to use the principles of Mendelian genetics. Since black is dominant over white, we can infer that the individuals with the dominant phenotype are homozygous dominant (BB) or heterozygous (Bb).

Let's assume that the population consists of Bb individuals. Given that 75% of the population has the dominant phenotype, the remaining 25% must have the recessive phenotype (bb).

So, the frequency of the recessive allele (b) can be calculated using the Hardy-Weinberg equation: q = √(0.25) = 0.5.

Now, to find the number of heterozygous individuals, we can use the equation 2pq, where p is the frequency of the dominant allele (B) and q is the frequency of the recessive allele (b). Since p + q = 1, we can calculate p using the equation p = 1 - q = 1 - 0.5 = 0.5. Then, we can substitute the values into the equation 2pq:

2 × 0.5 × 0.5 = 0.5

Therefore, there are 0.5 × 4520 = 2260 heterozygous individuals in the population.
