What information is not required on the nutritional portion of a food label?

Answers

i had this question and it was price

hope this helps


Answer:

Price

Explanation:

Out of all the options "Sizes" is the only option that is not included on the label.

The nutrition facts label is nutritional information that is written on the packaged food that shows the percentage of the nutrients present in the packaged food.

Different countries in the world has their nutrition guidelines for all packaged food that are been sold in daily basis

nutrition information that's well detailed helps the consumers to have a good eating habit and this information can only be produced by the producers.

Some information on the label includes;

1.)INGREDIENTS; the ingredients are usually arranged in certain order I.e from the major ingredients(highest quantity) to minor ingredients (lowest quantity) such as sucrose,additives and others. and any FDA- certified must be included.

2.)DAILY VALUE; It is used on food label to so that the consumers can plan a healthy diet, it provide the percentage of the nutrients that is contained in a serving of food.

3.)PORTION SIZE; is the amount of a food consume in single occasion.

List and explain the factors that influence blood pressure, and describe how blood pressure is regulated.

Answers

Arterial blood pressure reflects two factors:
How much the elastic arteries close to the heart can be stretched (their compliance or dispensability)
The volume of blood forced into them at any time. If the amounts of blood entering and leaving the elastic arteries in a given period were equal, arterial pressure would be constant. Blood pressure rises and falls in a regular fashion in the elastic arteries near the heart.

Could the mitochondrial DNA of either James Carnegie or Countess Xenia be used to try to identify the skeleton of Tsar Nicholas?

Answers

The answer is neither. Mitochondrial DNA is passed down the maternal line from mother to daughter. The Tsar Nicholas is a male, so mitochondrial DNA could not be used to identify his remains through kinship analysis. Traditional DNA markers or Y-chromosome markers would be more appropriate. 

Final answer:

The mitochondrial DNA of James Carnegie or Countess Xenia cannot be used to identify the skeleton of Tsar Nicholas.

Explanation:

The mitochondrial DNA of either James Carnegie or Countess Xenia could not be used to try to identify the skeleton of Tsar Nicholas because mitochondrial DNA is inherited maternally and Tsar Nicholas would not have inherited his mitochondria from either James Carnegie or Countess Xenia. Mitochondrial DNA can only provide information about maternal lineage. Therefore, it would be more useful to examine the mitochondrial DNA of Tsar Nicholas, any known maternal relatives, or other individuals directly related to Tsar Nicholas through a maternal line.

Which two muscle types contract by shortening of the sarcomeres? select all that apply?

Answers

There are three types of muscles namely; (1) cardiac muscles, (2) smooth muscles, and (3) skeletal muscles. Sarcomeres are the functional contractile unit of both cardiac and skeletal muscles; both of which are striated muscles. Smooth muscles, on the other hand, have no sarcomeres instead the contractile structures (actin and myosin) are dispersed within the cell body.

Consider the consequences of a mutation in the dna template sequence 5'atg3' to 5'ttg3': what is (a) the resulting change in the mrna codon and (b) the effect on the corresponding amino acid? see section 16.4 (page 344) .

Answers

a) The resulting changes in mRNA codon would be;
 CAU TO CAA; This because in the mRNA the base Thyamine is replaced by cytocine, therefore A would pair with Cytosine.

B) The effect on the corresponding amino acid would be a change from His to Gln. This mutation would result to a change form Histidine to Glutamine; this is because the codon CAU codes for Histidine while CAA codes for Glutamine.

A plant that has been raised in a sterile environment shows symptoms of a viral infection. how would you explain this?

Answers

The answer would be: The viral infection was acquired by vertical transmission.

Vertical transmission happens when the plant parents are infected before the plants detach from it. It could happens during asexual reproduction or in seeds of sexual reproduction.
That means, the infection spread before the plant raised in the sterile environment. 
This can be explained by the concept of vertical transmission of a virus, i.e., the virus is inherited from a parent. During asexuak reproduction, the offspring is genetically identicle to the parent. Here, during the development of the offspring through the stem, root or bulb of the parent, the parent's virus is passed to the offspring. In sexual reproduction, viral transmission occurs as a result of seed infection.

"abnormal enlargement of air sacs in the lungs can lead to which condition"

Answers

The correct answer is emphysema.
Emphysema is the enlargement of air sacs in the lungs.
It is a long-term, progressive disease of the lungs that primarily causes shortness of breath. People who have emphysema, their air sacs in the lungs (alveoli) is damaged. Over a period of time, the inner walls of the air sacs weaken and rupture creating larger spaces instead of many small ones. Normally, the lung tissue holds these small airways called bronchioles, open, allowing air to leave the lungs on exhalation. However, when the lung tissue is damaged like in the case of emphysema, these airway collapse, making it difficult for the lungs to empty and the air (gases) becomes trapped in the alveoli thus causing impaired gas exchange.

Since dna has a negative charge in which direction will it go in the gel if there are bubbles what does this mean

Answers

The direction will be toward the positive charge on the other end. If there are bubbles it means the current is running. DNA  are molecules which stores genetic material. DNA is negatively charged because of the phosphate backbone since they are negatively charged also. To separate DNA using agarose gel electrophoresis, the DNA is loaded into precast wells in the gel and a current applied. Since the phosphate backbone of the DNA molecule is negatively charged, the fragments of DNA will migrate to the positively charged anode.

Birds migrating, cats chasing prey, sea turtles moving toward the ocean immediately after birth, and joeys moving to the mother's pouch immediately after birth are all examples of ________.

Answers

The answer is 'instinct'. This is innate complex behavior exhibited by an organism that is not learned. Some common examples are dogs shaking themselves dry when wet, honeybee communication via intricate dances, animal courtship behavior during mating season and the building of nests by birds.

Final answer:

Innate behaviors are hardwired actions that occur naturally in animals, such as migration in birds and imprinting in geese, where they follow an object that resembles their mother after birth.

Explanation:

Birds migrating, cats chasing prey, sea turtles moving toward the ocean immediately after birth, and joeys moving to the mother's pouch immediately after birth are all examples of innate behaviors. Innate behaviors are those that are hardwired into an animal's biology and are performed without prior experience or training. These behaviors occur naturally in all members of a species. Migration is one such behavior, where animals move from one place to another, often in response to environmental changes, such as the change of seasons. Birds, for example, migrate to find warmer areas with more food during the winter months.

Imprinting is another example of innate behavior, seen in species like geese, which refers to the critical period shortly after hatching when they form attachments and follow objects that resemble their mother.
