Answer:
75%
Explanation:
This question involves a single gene coding for the ability to taste the chemical PTC. The allele coding for the ability to taste (T) is dominant over the allele coding for the inability to taste (t). This means that an heterozygous individual will have the ability to taste PTC.
According to this question, if two heterozygous tasters (Tt) cross to have a large family i.e. Tt × Tt, the following gametes will be produced by each parent;
Tt = T and t
Using these gametes in a punnet square (see attached image), the following proportion of offsprings will be produced:
TT, Tt, Tt - Tasters (3/4 or 75%)
tt - Non-taster (1/4 or 25%)
Note that based on the question asked, there is a 75% probability that their first child will be a taster because there is equal segregation of alleles into gametes.
Answer:
· Nitrogen fixation
· Nitrification
· Assimilation
· Ammonification
· Denitrification
Explanation:
Nitrogen fixation is the process where nitrogen is converting into ammonium.
Nitrification is the process of ammonium oxidation into nitrate.
Assimilation is the process where animals and plants receive NO3. Plants are using this nitrate for proteins and acids.
Ammonification is the process where the nitrate that is contained in plants and animals is recycled after their death.
Denitrification is e the last process in this cycle and during this process nitrate is converting to gases.
Answer:
Bringing healthy meals to the table can be difficult if you are trying to save money. Consider serving low-budget meatless meals once or twice a week. Meatless meals are made from beans, lentils, vegetables, and whole grains. These plant-based proteins tend to be less expensive and offer more health benefits than meat.
Explanation:
A diet based on plant-based products, in which fruits, vegetables, cereals, beans, legumes and nuts stand out, is rich in fiber, vitamins and other nutrients. In addition, non-meat eaters (vegetarians) generally eat fewer calories and fat, have less weight, and have a lower risk of heart disease than non-vegetarians.
Even reducing meat intake has a protective effect. Research indicates that those who eat red meat are at increased risk of heart disease, stroke, or diabetes. Processed meats also increase the risk of dying from these diseases. Also, what you don't eat can also affect your health. Diets reduced in nuts, seeds, shellfish, fruits and vegetables also increase the risk of death.
Answer:1%
Explanation:
The correct answer is less than 8% of DNA is active. But here's only 3options are available so the answer is 1%. Other DNA is in an inactive form. Only 8% of DNA is performing functions of the body actively.
