Answer:
Used cross breeding to purposely breed plants. Studied a variety of pea plant traits. studied several generations of pea plants.
Explanation:
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.
Answer:
This experiment proved that DNA replicated semiconservatively; half the original polynucleotide is conserved in each of the two copies
Explanation:
Semi-conservative mode of replication means that the two strands of DNA unwind from each other, and each of themacts as a template for synthesis of a new, complementary strand. As a result, two formed DNA moleculesc ontain one original strand and one new strand.
Meselson and Stahl experiment showed this model by labeling the DNA of bacteria across generations using isotopes of nitrogen ( patterns of DNA labeling showed the mode of replication).
Answer:
Well for one photosynthesis gives out oxygen. This makes all animals able to live. So in that way it helps us and the world around us. Without photosynthesis we also could not eat food. No animals could live and no plants ould live. VERY IMPORTANT!
Explanation:
Yes, our distance from nature and our chronic immunological discontent could be related. Nature may be the cause of allergic problems.
<h3>What is an allergy?</h3>
Allergy is a common immune response produced by certain substances that alter the stability of the immune system.
Allergy may be caused by different materials present in nature that alter our immune system.
For example, pollen grains may cause allergic responses such as inflammation and thus produce chronic immunological problems.
