Answer
68.6 m
Explanation:
<u>Given-</u>
- Mass = 0.5 kg
- Potential energy = 34.3 J
<u>To find -</u>
Height of the tree upto which the squirrel climbed.
<u>Solution-</u>
Potential energy of a body = mgh
34.3 = 0.5×h (mg = 0.5kg)
h = 34.3/0.5 
 = 68.6 m

Answer:
A. Dominant alleles often encode functional products, whereas recessive alleles often do not encode functional products
Explanation:
One gene can have it's variant forms called allele but in one individual only two allele form of a gene can be present. These two allele form can be the same(homozygous) or different(heterozygous). A dominant allele often encode a function protein of product while recessive allele often code for non- functional product.
Therefore when the dominant allele is present in the chromosome then function products are formed which can be seen in the phenotype and even a single dominant allele produce the functional product like in heterozygous condition so phenotype in heterozygous and homozygous dominant condition appears same. So the correct answer is A.
