False, in order to change a plant you would need to alter the DNA of the seed
Epithelial tissue covers the outside of the body and lines organs

Answer:
Allele for short tail is a dominant phenotype.
Explanation:
In the second generation , the cross between a group of short tailed mice produces either short tailed or long tailed species.
This means the short tailed mice must be having the allele for long tail trait but did not expressed it.
Hence, when two alleles are presents and one is expressed while the other is suppressed then allele expressing its trait would be the dominant phenotype.
Hence, the allele for short tail is a dominant phenotype.
Cross between two short tailed mice will be as follows
Ss * Ss
SS, Ss, Ss, ss
Out of four three are short tailed while one "ss" is long tailed.
Answer:
b. They are carried throughout the body in the bloodstream, and each hormone affects target cells that have receptors for it.
Explanation:
Hormones are secreted by hormonal glands after they get signals to secrete or release the hormone. Then these hormones are carried by the bloodstream to their destination. Each hormone has its target organ or tissue which do not response to other hormones because it the cells in those tissue have specific receptor which binds to specific hormones.
For example, luteinizing hormone in male is produced by the pituitary gland which reach to the testis through blood and influence the Leydig cell to release testosterone. So Leydig cells have receptors for LH not for insulin hormone so it binds specifically to LH hormone. So the correct answer is b.
The answer is hydrogen bonding.
Hope this helps.
