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%.
Climate change as been the most of the problem
Answer:
Umm...I'm not sure if this is a question where there is MC but if not, the the answer would most likely be, "By actually doing then saying"
Explanation:
The tissue that water travels up from the roots to shoots in a deciduous tree is xylem.
<h3>
What is xylem?</h3>
- Xylem is one among the two types of transport tissue in vascular plants, the opposite being phloem.
- Transport water from roots to stems and leaves is the main function of xylem, but it also transports nutrients.
- The word xylem springs from the Ancient Greek word ξύλον (xylon), meaning "wood"; the best-known xylem tissue is wood, though it's found throughout a plant. The term was introduced by Carl Nägeli in 1858.
- The long tracheary elements are the most distinctive xylem cells that transport water. Tracheid and vessel elements are distinguished by their shape; vessel elements are shorter, and are connected together into long tubes that are called vessels.
