Answer:
It's impossible to predict the phenotype of the offspring by only observing the parents because DNA from their grandparents can affect the offspring as well.
Explanation:
DNA is combined from the parents to create offspring. When that offspring reproduces their children not only possess DNA from their parents but from their grandparents as well. Mixing together two separate DNA's from two different family trees can result in rare genetic mutations which results in the offspring looking different from their parents but showing resemblance to their grandparents. This is why you have to look at the phenotypes of more then just the two parents because there are more possibilities, including what their grandparents looked like.
Answer:
Invertebrates are the organisms in which backbone or vertebral column is absent.
The three macroinvertebrate categories are annelids, mollusks and arthropods.
Annelids are the organisms having segmented body. They are found in moist places. Examples are leeches and earth worms.
Mollusks are the organisms which are enclosed in a calcium carbonate shell. Examples are snails and slugs.
arthropods are the invertebrates which have segmented body and jointed appendages. Examples are insects and crustaceans etc.
Answer:
- Reduced risk of neural tube defects- <u>diet adequate in synthetic form of folate </u>
-
Reduced risk of hypertension and stroke- <u>diet low in sodium and high in potassium </u>
-
Reduced risk of cardiovascular disease- <u>fatty acids from oils present in fish </u>
-
Reduced risk of some types of cancer- <u>diet rich in fiber</u>
Explanation:
As you may already know, the adequate intake of certain nutrients is very beneficial to our body and to improve and maintain our health. That's because these nutrients act in the construction of essential molecules to keep our body functioning in a healthy and adequate way. Among the numerous nutrients necessary for our health, we can mention that the adequate intake of folate has the ability to reduce the creation of possible defects in the neural tube, while a diet rich in potassium can reduce the risks of hypertension, especially if accompanied by a low sodium diet. Following this same reasoning, a diet rich in fiber can reduce the risk of cancer, in addition to promoting good bowel function. Last but not least, a diet rich in fatty acids from fish can reduce cardiovascular disease.
