Answer:
Enzymes proofread the DNA after the DNA has been replicated and replace any mismatched nucleotides.
Explanation:
DNA replication occurs to make exact copy of original DNA. Transcription of genetic information to an intermediate mRNA occur after replication after which we have translation of genetic information into amino acids.
In the process of replicating DNA error can occur and then enzymes proofread the work for errors. Enymes DNA polymerase proofs read the replication,removes and replace the nucleotide base from where error occurs. It proof read after the DNA replication has occured.
This enzyme is also involve in DNA replication.
Answer:
Cellular respiration is an important metabolic process that moves sulfur from living organisms into the atmosphere.
Explanation:
Cellular respiration is mainly based in the carbon cycle, because most of the compounds involved have carbon in it structure.
sulfur can release to the atmosphere by burning fossil fuels or by volcanic eruptions in the form of SO2, this is a normal gas, despite is a toxic gas, but the quantities that are formed are too little.
Like a cycle, the animals can obtain sulfur if they eat plants because the plants take from the soil the sulfur and transformed it into minerals like sulfates.
Like a cycle, the element sulfur just change from one substance to another.
Correct answer: A) Extension
Extension is a physical position that occurs when angle between the bones and the limbs of joint increases.
It takes place when there is a contraction of muscles and bones move the joint from a bent to a straight position, it is opposite of flexion, in which the angle between the bones and the limb at the joint decreases.
Example: During straightening of the leg, the angle between the tibia and femur increases, which shows extension has taken place.
Answer:
Bacteria capsule.
Explanation:
The bacteria capsule is a layer of polysaccharides that is around the bacteria membrane. Its principal function is to protect the bacteria from dehydration, destructive toxins, and cells that can destruct the bacteria, such as phagosomes. As a result, the bacteria have a higher probability of surviving and colonizing.
