Answer:
The moon
Explanation:
Most nocturnal plants, animals and insects, like moths, use the moon as their guide through the night. This is why insects are attracted to light in the nights
Adenine and thymine are complementary bases, as well as cytosine and guanine. Complementary bases bind always with each other, and never with another base. Cytosine and guanine are joined together by 3 hydrogen bonds and thymine with adenine with 2 hydrogen bonds
The best conclusion is to do the experiment twice
Answer:
d. 1/3
Explanation:
Given, M is a dominant allele which is responsible for tailless kittens and m is recessive wild type allele which leads to kittens with tail. M is a lethal allele which means that if it is present in homozygous condition, the kitten will not survive. So the Manx cats should be heterozygous i.e. Mm.
When they mate, Mm X Mm :
M m
M MM Mm
m Mm mm
1/4 kittens will have MM genotype so they will not survive. Out of the remaining kittens, 1/3 will be mm and hence they will have normal tail. Remaining 2/3 will have Mm genotype like their parents and will be born without tail. Hence, there is 1/3 probability that one of the four kittens will have a normal tail.
