They typically sleep about 16-17 hours a day; that’s a lot!
Animals that use echolocation. Bats, whales, dolphins, a few birds like the nocturnal oilbird and some swiftlets, some shrews and the similar tenrec from Madagascar are all known to echolocate.
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.

A. The Geiger counter
being used to detect radiation is broken.
B. Two or more samples
we accidentally swapped, causing confusion.
C. A virus contaminated
the reaction in which the probe was made.
D. The human genome
might contain at least one viral gene.
The answer is D. This means that the viral DNA inserted itself
in the human tissue DNA aand became a prophage. A prophage is a latent form of
viral infection where the inserted viral DNA has no interference with the host
cell biochemical processes. The prophage will be present in the daughter cells
of the host cells.
