bearhunter [10]

Answer:

The answer is 6.4 × 10^{-20} Joules

Explanation:

This question wants to effectively test your knowledge of the names of the negative powers of 10, so first of all, before calculating, let me explain what each of the symbols in the units given in the question means:

Force = 8.0 pN = 8.0 × 10^{-12} N

displacement = 8.0 nm = 8.0 × 10^{-9} N

Now let us calculate the work.

work = Force × Displacement

work = 8.0 × 10^{-12}  × 8.0 × 10^{-9} = 64 × 10^{-21}

= 6.4 × 10^{20} Joules (in standard form)

What are the similarities between DNA and RNA molecules?
liraira [26]

Answer:

Both DNA and RNA are made up of monomers called nucleotides.

Both RNA and DNA both have 3 nitrogenous bases: Adenine, Cytosine and Guanine.

They are both necessary for the cell to produce proteins.

DNA and RNA both contain pentose sugars.

DNA makes mRNA which then is translated into protein.

Answer:

Charles Darwin

Explanation:

Natural selection, most famously proposed by Charles Darwin, states that when presented with an environmental challenge, some individuals in a species will develop adaptations to face these challenges. Successful individuals will be more likely to mate and their offspring will inherit these adaptive traits, and will continue to pass for generations.

In this sense, plants face the challenge of the cold. Those that adapt to the cold will survive and reproduce, those that can't adapt to the cold will die. Eventually, only plants that can tolerate the cold will survive.

Please help!!<br> How do living organisms maintain homeostasis on a cellular level?
Oksi-84 [34.3K]

Answer:

Hello

To maintain homeostasis, unicellular organisms grow, respond to the environment, transform energy, and reproduce. A single-celled, or unicellular, organism does everything you would expect a living thing to do.
