Capsid is the component of a virus that is lacking in its cell
A capsid is the protein shell that surrounds a virus. Capsids functions by protecting the nucleic acids of a virus while interacting with the host environment. Capsids are made up of many oligomeric structural subunits that contains the protein; protomers. Capsids are generally grouped based on their structure. The common ones are helical and icosahedral.
Because the acid helps the stomachs digestion system digest
Answer:
The correct answer is 35 percent.
Explanation:
Allele D produced tiny ears, and allele d produces normal ones. If a heterozygous male with Dd mates with the homozygous female with dd, then generally, the expected offspring produced will be 50 percent with tiny ears, and 50 percent with normal ears.
However, in the given case, the penetrance is 70 percent. Thus, the probability of the offspring with tiny ears will be:
Penetrance = 70 %
Probability = 70 % of 50 % of 100
= 70/100 * 50/100 * 100
= 35 %
Hence, the probability of the offspring with tiny ears is 35%.
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.
