A controversial issue of toxicology is the use of chemical additives in food.
Food additives are substances intentionally added to foods for the purpose of preserving, enhancing or modifying their physical, chemical, biological or sensory properties without impairing their nutritional value. However, it is necessary to control the use of these substances, as ingestion of these substances may pose health risks.
Additives are found in most processed foods, such as cookies, breakfast cereals, soft drinks, jellies, artificial juices, candies and a host of other foods in the diet of Brazilians, especially children.
Thus, its consumption should be controlled, as the health risk is confirmed by a sum of scientific studies. The three main ills associated with excessive consumption of these substances are cancer, food hypersensitivity and attention deficit hyperactivity disorder.
Some audiences are even more vulnerable to consumption, such as pregnant women, the elderly, people with little food and children under three years. In the case of children the attention should be greater because the digestive and urinary systems are not yet fully prepared to process these substances.
The more industrialized the product, the more chemical additives it will have. The ideal is to prepare fresh products at home. However, as is often not possible, it is important that you read the label and choose the products with the least additives.
b. Vertebral column
c. Five digits
d. Mammary glands
e. Endothermy
f. Placenta
Answer: A) Hair and D) Mammary glands
Explanation:
Synapomorphies of mammals are hair and mammary gland as, mammals are the distinct from the other tetra-pods having hair,mammary gland and three bone ear. The three unique trait of mammals included three bones ear malleus,stapes and incus, presence of the hair and mammary gland for the production of milk.
The wood is xylem, and the bark is phloem. So, if you reverse the two, the tree is unlikely to be able to support its own weight.
Vasculartissue is an intricate conductingtissue found in vascular plants that is made up of multiple cell types.
The xylem and phloem are the primary components of vascular tissue. From within, those same two tissues transport fluid as well as nutrients.
In plants, cambium is a layer of actively dividing cells that exists between xylem (wood) and phloem tissues and is responsible for the secondary growth of stems and roots.
A cambium is a tissue layer in plants that provides partiallyundifferentiated cells for plant growth.
It is found between the xylem and the phloem. A cambium is also a cellular plant tissue that grows phloem, xylem, or cork by division, resulting in secondarythickening.
The wood is called xylem, as well as the bark is called phloem. If the two are reversed, the tree is very unlikely to be able to endorse its own weight.
Thus, this can be the consequence of reversing the xylem and phloem.

Answer:
C: A solid metal ball in the middle of a pool of liquid.
Explanation:
Since the student is studying the earth, the core area is made up of a solid metal ball in the middle of a pool of a liquid.
Answer:
Explanation:
The disease sickle cell anemia is caused by homozygosity for a mutation:
Albinism is a recessive trait:
The genes S/s and A/a are linked and separated by 1 map unit.
Remember that 1 mu means that 1% of the gametes produced by an individual will be recombinant.
Son: Sa/sA
The gametes he can produce are:
Since the frequency of recombination is 1% (or 0.01), each recombinant gamete has a frequency of 0.005 (since there are two possible recombinant gametes).
The parental gametes will appear with a frequency of 0.99, each of them with a frequenct of 0.495.
Daughter: SA/sa
The gametes she can produce are:
In order for them to have an albino child with anemia (sa/sa), the gamete sa from each parent had to be produced and fused into the zygote. Since the production of gametes by each parent is an independent event, the probability of having sa/sa offspring can be calculated as:
Prob. sa gamete son × Prob. sa gamete daughter = 0.005 × 0.495 = 0.0025
The probability that a child of theirs will be an albino with sickle-cell anemia is 0.25%

higher than
the normal healthy
body's result.
Why?
Athlete inhale high amount of energy s compared to normal healthy person.
The athlete's result will be higher than the normal healthy body's result for oxygen because athlete do hard activities which needs high amount of oxygen in order to release high amount of energy in the form of ATP. This energy is used by the body of athlete in their hard activities.
While on the other hand, the normal healthy person inhale less oxygen because he do normal activities and does not need high amount of energy for that activities so we can conclude that athlete inhale high amount of energy s compared to normal healthy person.
