Answer:
(A). Energy is lost when machines don't work right.
Explanation:
The false statement from the choices is that energy is lost when machines do not work right.
The law of conservation of energy states that "energy can neither be created nor destroyed , they can only be converted from one form to another. "
- Option B is clearly covered by the statement of the law. All the energy of the universe is already created.
- Energy cannot be destroyed tallies with the Option C.
- Energy is transformed from one form to another validates the fourth choice. We can covert from thermal to mechanical energy and vice versa.
The only odd choice is that energy is lost when a machine doesn't work right.
Flowers and their insect pollinators are a classic example of coevolutionnnn
Add to one that the other will explode because it will create a chemical reaction. For 2 you are right it will kill you to drink salt water.
Answer:
Both leading and lagging strands
Explanation:
DNA replication is the enzyme of DNA replication that forms new DNA strands. However, the enzyme cannot start the process of synthesis of new DNA strands by itself but needs small primers. Primers are the small RNA sequences synthesized by RNA primase on both leading and lagging strands.
These primers are elongated by DNA polymerase by the addition of deoxyribonucleotides according to the sequence of the template strand. Since DNA replication on both lagging and leading strand is carried out by DNA polymerase, RNA primers are present on both lagging and leading strands.
Answer:
recombination frequency = 4.5% or 4.5mu
Explanation:
to calculate the frequency of recombination between these genes
we have,
recombination frequency = [ number of recombinnants/total number of offsprings) x 100
total offspring = 88 + 103 + 6 + 3
total offspring = 200
Gl ra 88............................ parent
gl Ra 103.........................parent
Gl Ra 6..................................... recombinant
gl ra 3................................................ recombinant
recombination frequency = {6+3/88 + 103 + 6 + 3} x 100
recombination frequency = 9/200 x1oo
recombination frequency = 0.045 x 100
recombination frequency = 4.5% or 4.5mu
