If a double-stranded dna sample were composed of 10 percent thymine, what would be the percentage of guanine?.
The strand of DNA will be composed of 40% guanine.
We know that each base have complimentary bases, so since there are 10% thymine, we can expect that there will also be 10% adenine. That leaves us with 80%. There are two bases left, guanine and cytosine, so if you divide 80% by 2, you will get 40%.

A lipid-soluble hormone binds to its intracellular receptor and then binds to a portion of DNA called a ______ element (HRE)
A lipid-soluble hormone binds to its intracellular receptor and then binds to a portion of DNA called a hormone-response element (HRE). It is fundamental to activate signaling pathways.
Hormone-response elements and signalingA hormone response element (HRE) is a short nucleotide sequence capable of binding a hormone-receptor complex.
Hormone response elements are located in the promoter gene regions where they function to activate transcription.
The activation of transcription by means of a hormone response element leads to the activation of a given signaling pathway.

Why are spores, as opposed to sperm, the primary means of dispersal in moss?.
spores are light & small & encapsulated
The spores are very resistant to the the external environment since they are encapsulated structures , this type of dispersal helps past against natural calamities and promotes more living of the plant in further generations in extreme conditions . Since they are light weight and have small size they can be dispersed easily so helps in diversification of the plant in the area . These advantages are not well suited for sperms. Moreover, in mosses, the sperm requires water for the movement to meet the ova cells to make zygote.
