Gelneren [198K]

Answer;

Quaternary structure

Explanation;

-Amino acids link together end-to-end forming the primary structure of proteins.

-Chemical properties of amino acid groups within a sequence interact with one another in secondary protein structure resulting in hydrogen bonding and chain folding.

-Intramolecular bonding of polypeptide chains produces numerous alpha helices and beta sheets.

-Globular and fibrous shapes are created with tertiary structure of proteins caused by further folding due to disulfide bridges, hydrophobicity and Van der Waals forces.

-More than one globular or fibrous protein subunit now interact to produce quaternary structure, which results from ionic, hydrophilic, and hydrophobic interactions.

stepladder [879]

The fatty acids in the tail of a phospholipid molecule are non-polar and hydrophobic.

Fats that you take in from your food is used to build membranes. Membranes can be represented by models such as The Fluid Mosaic Model, which displays the phospholipid bilayr, and other tissues on the membrane.

8. In a population of beetles, there is a gene for color with two codominant alleles. The allele R leads to red beetles and the
Eddi Din [679]

Answer:

The genotypic frequency = 1:1

The phenotypic frequency = 1:1

Explanation:

Given that:

The allele → R = Red beetles

The allele → B = Blue beetles

Since the gene color shows a codominant allele

The Red Beetle = RR

The blue beetles will be = BB

The heterozygous beetle will be = RB

∴

The punnet square showing the crossing of RB × RR is:

                R                   B

R                RR               RB

R                RR               RB

The result shows that we have two red beetles and two heterozygous beetles.

Hence;

The genotypic frequency = 1:1

The phenotypic frequency = 1:1

1. Suppose that a sample of beef broth initially contains
iren [92.7K]

From the calculations, the rate of growth of the culture is 2.88.

<h3>What is exponential growth problem?</h3>

We apply the exponential growth problem when there is an exponential increase.

Thus, we have; P =Poe^rt

P = amount at time t

Po = amount originally present

t = time taken

r = rate of growth

1.6 × 10^6 = 16e^4r

1.6 × 10^6/16 = e^4r

1.0 * 10^5 =  e^4r

ln 1.0 * 10^5 = ln e^4r

11.5 = 4r

r = 11.5/4

r = 2.88

yKpoI14uk [10]

Answer:

In the light-independent reactions or Calvin cycle, the energized electrons from the light-dependent reactions provide the energy to form carbohydrates from carbon dioxide molecules.  

Explanation:

After the energy is transferred, the energy carrier molecules return to the light-dependent reactions to obtain more energized electrons.
