Lactose when digested, it is hydrolyzed by lactase into its monomers, which are then absorbed by blood. Following are test resul

ts from a person done after 2 hours of drinking a lactose rich solution. The blood glucose levels were 80, 110, 140 and 160 mg / dL tested for every 30 minutes. Based on this information does this person have lactose intolerance?

Answer: Based on the information, the person DOES NOT have lactose intolerance because glucose levels significantly increases in normal individuals after a lactose rich meal.

Explanation:

Lactose is a disaccharide carbohydrate which when taken (found mostly in diary products) is hydrolyzed by lactase into its monomers, which are then absorbed into the blood. The hydrolysis of lactose gives glucose and galactose which is carried out by the digestive enzyme lactase. Deficiency of the lactase enzyme gives rise to a disorder known as LACTOSE INTOLERANCE.

The diagnosis of lactose intolerance or lactase deficiency can be confirmed by measuring the plasma glucose concentrations, as in glucose tolerance test, after giving an oral load of lactose rich solution. If the disaccharide (lactose) cannot be hydrolysed, the constituent monosaccharides cannot be absorbed and the concentrations of plasma glucose rise VERY little.

But the fasting blood glucose done after 2 hours of drinking a lactose rich solution showed a typical rise in blood glucose levels which were 80, 90, 100, 110 and 120 mg/ dL tested for every 30 minutes. This indicates that the individual does not have lactose intolerance because the glucose gotten from hydrolysed lactose was absorbed and cause a significant rise in blood levels.

tresset_1 [31]

Hello. This question is incomplete. Also, you forgot to show the flowchart. The flowchart is attached below and the full question is:

The flowchart below shows the three generations of a cross between a pea plant that has yellow pods and a pea plant that has green pods. Green pods are the dominant trait. The flowchart is missing the labels that describe the traits.

In which squares should the phrase “Green pods” appear?

1.A and D  2.B and E  3.A,C and D  4.A,B,C,D and E

Answer:

3.A,C and D

Explanation:

As shown in the question above, the flowchart shows the crossing of a pea plant with dominant features (green pods - AA) and a pea plant with recessive features (yellow features - aa). The crossing between plants with AA and aa alleles generates a completely Aa population, which in this case, has the dominant characteristic, that is, it has green pods. This is because the "Aa" alleles are called heterozygous and develop the dominant characteristic.

As we can see in the flowchart, the crossing between the two pea plants generated an offspring that is identified by table C, as we know this offspring has green pods and in the flowchart it is represented by a grayish rectangle. Therefore, we can say that the other gray rectangles represent pea plants with green pods, which are rectangles A, C and D.

Proteins have all of the following properties except enzymes
nevsk [136]

Proteins have all of the properties except genetic material.

<h3>What do you mean by Proteins?</h3>

Proteins may be defined as naturally emerging, extremely complicated substances that consist of amino acid residues joined by peptide bonds.

Proteins have the following properties:

  • They are enzymes.
  • Work as signaling molecules in numerous signaling.
  • They are involved in the transport of materials.
  • They provide a structural arrangement to the cells.

Therefore, proteins have all of the properties except genetic material.

What term is used to describe organisms composed of identical and unspecialized cells?
Sedaia [141]

Answer:

Embryo cell or totipotent cell

Explanation:

All organisms during their embryonic stage also known as totipotent cells are composed of cells that are identical in structure and function. These cells can differentiate at a later stage and have the potential to become any cell i.e heart cell, eye cell etc. Embryo is thus just a mass of unspecialized cell which undergo differentiation to then convert into pluripotent and form tissues and hence the organ.

Base your answer to the question on the passage below and on your knowledge of biology
Delvig [45]

Darwin concluded that the finches all shared a common ancestor but had  developed different beak structures.  The second sentence best describes as an ecosystem.

Explanation:

  • When Charles Darwin traveled to the Galapagos Islands, he observed 14 distinct varieties of finches on the islands Darwin also observed that each finch variety  ate a different type of food and lived in a slightly different habitat from the other finches, Darwin concluded that the finches all shared a common ancestor but had  developed different beak structures. The second sentence best describes as an ecosystem.
  • An ecosystem is a huge group of living organism such as plants,animals, micro-organisms in a particular area.
  • An ecosystem is a community of living organisms related with the nonliving components in the  environment, together interacting as a system.
  • its abiotic constituents, includes minerals, climate, soil, water, sunlight, and all other nonliving elements, and its biotic constituents, consists of all its living members.
