Answer:
If slim shelled snails have dainty shelled posterity and thick shelled snails have thick-shelled posterity then this is a decent proof that shell thickness is heritable.
In the genuine investigation they have watched however at first the number of inhabitants in snails had an arbitrary conveyance of shell thickness in the long run the nearness of a crab the predator lead to the determination of thick-shelled snails with the end goal that they are not consumed.Thickness of the shell is certain a heritable factor by qualities yet the choice or development of thick-shelled snails over the time is an unadulterated choice.
Answer:
C. 30 min minutes a day 5 days a week of moderate-intensity exercise or 20 minutes a day 3 days a week of vigorously intense exercise
Explanation:
The combination of aerobic and muscle-strengthening physical activity is crucial for a healthy lifestyle. Regular physical activity can help to reduce the risk of cardiovascular and chronic diseases, disability and premature mortality.
Adults need a moderate physical aerobic activity for a minimum of 30 minutes 5 days a week or 20 minutes of vigorous-intensity aerobic activity. A combination of these two can be done to achieve this goal.
A moderate-intensity physical activity, like <u>fast walking</u>, should produce a noticeable rise in heart rate and breathing. On the other hand, a vigorous-intensity activity, like <u>running</u>, should produce a large and bigger change in heart rate and breathing.
The muscle-strengthening activity, should be performed for a minimum of 2 days a week on two or more nonconsecutive days.
Explanation:
Oxygenic photosynthesis is composed of two stages: the light-dependent reactions and the light-independent reactions. The light-independent reactions use the ATP and NADPH from the light-dependent reactions to reduce carbon dioxide and convert the energy to the chemical bond energy in carbohydrates such as glucose.
During the lifecycle of the plant we can encounter both haploid and diploid forms.
