Answer:
Density = mass/volume = 57g/4.2 mL ≈ 13.6 g/mL
Explanation:
Mass = 57 g Volume = 4.2 mL
The density of mercury is ⇒ 13.6 g/cm3.
Trust me I got it wrong and it gave me this. I just did the instruction.
DNA has sequences that mRNA finds the pair for (ex. DNA says AGC, RNA says UCG)
with that, they only come in 3 nucleotide increments.
Answer:
D) Frequency results from environmental stresses, not dominance.
Explanation:
The allele frequency refers to the amount of frequency of a particular allele in a small population whereas the dominance and recessive are the measure of the effects of the allele on the population which decides the trait of an organism.
The frequency and dominance cannot be correlated with each other as the frequency of the allele in a population is the result of the environmental stress which are random and by chances, whereas the effect of dominance is not random but is the result of the favoured trait for survival.
Thus, Option-D is correct.
The main difference between the organisms are the uses of the appendage and the size and number of certain bones. The human arm is used for a variety of functions while the lizard's and the cat's are used for walking an climbing, the whale's for swimming, the frog's for support and the bird's and the bat's for flying.
Well, depending on how long the migration is, many of the animals (mainly birds) could get sick and die, lowering the population. They could be shot by hunters, lowering the population. The children of the population could get left behind and lose their way, lowering the population. I'm not entirely sure how the population could grow other than them finding and staying with another group of their own kind. hope I was helpful! :)
