kykrilka [37]

Proteins that assist in the movement of substances across  can be classified into two types which are:

  • Carrier proteins
  • Channel proteins

<h3>What are Proteins?</h3>

These are biological molecule which consists of amino acid sequences and are involved in metabolic activities in the body.

They are also found in cells and help in the selective movement of molecules in and out of the cell.

A sample of food containing one type of a large molecule was treated with a specific digestive enzyme. Nutrient tests performed
Oxana [17]

The best answer is starch.

Starch is a type of carbohydrate.

Carbohydrates are made of simple sugars, namely glucose. A simple sugar is a single molecule of a sugar. A single sugar  molecule is called a monomer.

Starch is made of many monomers or units of glucose linked together and is thus called a polysaccharide. When it is broken down, the result is its many glucose units are separated from each other by breaking the chemical bonds that hold them together, and are thus released as simple sugars.

In 4 o'clock flowers, red is dominant to white, but the heterozygote is pink. What is the phenotype ratio of crossing red 4 o'cl
Ne4ueva [31]

Answer:

Phenotypic ratio = 1 Red : 1 Pink

Explanation:

This phenomenon exhited by the gene coding for flower colour in four o'clock plants is called INCOMPLETE DOMINANCE i.e. the red flower allele (R) is not completely dominant over the white flower allele (r), hence, a third intermediate pink phenotype (Rr) is formed in an heterozygous state. The red and white flowers will only be expressed in a RR and rr genotypes respectively.

In a cross between a red-flowered 4 o'clock plant (RR) and a pink-flowered 4 o'clock plant (Rr), the gametes:

R and R will be produced by the red-flowered plant while gamete R and r will be produced by the pink-flowered plant. Using this gamete in a punnet square, one will have four possible offsprings in which two will be phenotypically red-flowered (RR) and two phenotypically pink-flowered (Rr). i.e. 2RR:2Rr

Hence, the phenotypic ratio is 1:1 Red to Pink flower
