Answer:
A radioactive (unstable) phosphorus isotope is made to replace a nonradioactive isotope of phosphorus in the molecule
Explanation:
Phosphorus has both unstable (radioactive) and stable isotopes. In any compound that contains phosphorus, the phosphorus atom present may be either a stable isotope of phosphorus or an unstable isotope of phosphorus.
However, if the molecule contains a stable nonradioactive isotope of phosphorus, it is possible to convert this isotope in the molecule to the unstable radioactive isotope by carefully carrying out exchange reactions in which the phosphorus isotope replaces the nonradioactive isotope in the molecule.
This is usually done in order to create radioactive tracers which are used to study chemical reactions and biochemical processes.
Answer:
12-day litter weight is a trait that has an important genetic influence and therefore also a high response to selection
Explanation:
Heritability is a statistical measure of how much of the variation in a given trait can be attributed to genetic differences and how much of trait variation is due to environmental factors. A heritability value close to 1 indicates that almost all of the variability is due to genetic factors, while being poorly influenced by environmental factors. In this case, 12-day litter weight is a trait that exhibits an important genetic component (i.e., a high heritability value), thereby the correlation between parent and offspring will be high and lines selected for this trait will show a high response to selection.
Schools have to give proper meals and carbohydrates to students.
<h3>What is a balanced diet?</h3>
A balanced diet is one that includes a variety of foods in the right amounts and ratios to meet the body's needs for calories, proteins, minerals, vitamins, and other nutrients. A small portion of the diet is also set aside for extra nutrients to last through the brief period of leanness. In this situation, we must choose a unique menu that offers the
In this context, we have to first prepare the list of the number of carbohydrates, lipids, and proteins and then we have to identify the maximum amount required in the meal. then observe the common food in the school.
