Ecological efficiency is the term used to describe how much energy will be passed from lower food pyramid level into the higher level. The amount of energy in primary level will be much higher than tertiary. The difference of level of tertiary(3) with primary(1) would be two level.
Assuming that the ecological efficiency is 10%, then the <span>primary consumer level would be: 50 kcal * 10^(3-1)= 5000 kcal</span>
they might conserve water
Answer:
The difference is:
a) Positive feedback increases a change while negative feedback reduces a change.
b) Positive feedback occurs specific situations while negative feedback occurs in the body.
c) Positive feedback break down the homeostasis while negative feedback maintain the conditions of homeostasis.
d) Positive feedback has less frequent mechanism while negative feedback has more frequent mechanism.
e) Positive feedback enhances change while negative feedback resists change.
f) Positive feedback has a wider range while negative feedback has a narrow range.

Answer:Rhythm
Explanation:
This is because rhythms are repetitive, cyclical patterns of behavior generally. For example waking, eating are examples of rhythm for a baby.
The correct answer is: C) the place where the parent DNA becomes unzipped during DNA replication is called the replication fork.
DNA Polymerase doesn't build DNA from scratch, rather it adds the correct nucleotides to the complementary parent strand.
DNA Polymerase adds nucleotides in the 5' to 3' direction, not the 3' to 5' direction.
DNA is made semiconservatively, meaning that there is a template strand from the parent DNA with a complementary strand being the new daughter strand.
The strand that is made continuously is the leading strand. The lagging strand is not made continuously, as it requires the use of Okazaki fragments.
