Answer:

This food is not suitable for a person who has diabetes 2.

Explanation:

Type 2 diabetes is characterized as a disorder that does not allow the body to use ibsuline properly, creating a major imbalance in the organism and causing the accumulation of sugar in the blood.

The diet of people who have type 2 diabetes should be free of carbohydrates, for this reason, that person should limit their intake of fruit noodles, for example.

The diet of those who have type 2 diabetes should be rich in: whole grains, legumes, vegetables and fruits in small portions, meats, good fats, oilseeds and dairy products.

In a population of heffalumps, there is a single gene that controls the presence of hair. The H allele, which is a complete domi

maksim [4K]

<h2>Frequency of allele </h2>

Explanation:

Hardy Weinberg Equilibrium is used to calculate the allelic as well as genotypic frequency

Allelic frequency of dominant and recessive allele is represented by p and q respectively whereas genotypic frequency of dominant genotype is represented by $p2$ and $q2$ respectively

Given:

H allele (p) = hairy heffalump (dominant)

h allele (q) = hairless heffalump (recessive)

36% of heffalump population is hairless represents the % of recessive genotype, hh ( $q2$ ) =36%

Calculation of frequency of the h allele (q) :

Frequency of genotype hh ( $q2$ ) will be: 36/100=0.36 or 0.6*0.6

Frequency of h allele (q) will be 0.6

zaharov [31]

Answer:

The source of Calcium (Ca⁺⁺) for the skeletal muscle cells is the sarcoplasmic reticulum, the main store of intracellular Ca⁺⁺.

Explanation:

Calcium (Ca⁺⁺) is an ion that plays an important role in muscle contraction, a process that requires high cytoplasmic concentrations of this ion to promote myofibrillary activity.

The sarcoplasmic reticulum (SR) -equivalent to the endoplasmic smooth reticulum- is an organelle that regulates the contractile activity of skeletal muscle. The two terminal cisterns of the SR attach to the T-tube, forming a triad, which surrounds the myofibrilla.

Once the muscle cell receives the signal to contract, the Ca⁺⁺ channels are opened and allow Ca⁺⁺ to enter the cell, promoting the exit of this cation from the SR and increased its cytoplasmic levels. This stimulates muscle contraction.

In the diagram below, X represents a process that causes a protein to unfold and stop functioning. Process X is most likely caus

Elodia [21]

Answer:

<u>Temperature</u> is most likely the reason of protein unfolding (denaturation).

Explanation:

In the figure attached, coiled (3-dimensional) protein structure is changed to 2 dimensional structure in which protein is unfolded. This is most likely the result of heating proteins which destroys the hydrogen bonds and non-polar hydrophobic interactions that are necessary to establish the tertiary structure of proteins. Principally, increased temperature results in the increased kinetic energy of atoms within a molecule. If the amount of heat is sufficient to break the hydrogen bonds, protein molecule can unfold to 2D structure as shown in the figure.
