Answer:
Energy is used up while running, and cellular respiration needs oxygen to produce more energy. Energy is used up while running, and cellular respiration needs carbon dioxide to produce more energy.
Explanation:
Answer:
It wouldn't be able to migrate to the cell's poles.
Explanation:
During anaphase, microtubules attach the chromosome's centromeres and start dragging them towards the poles of the cell. In mitosis, this causes the separation of both sister chromatids for each chromosome, and each chromatid migrates to a different pole. In meiosis, first each homologous chromosome is separated by the same process, and then the sister chromatids are separated during anaphase II. If a chromosome doesn't have centromeres, microtubules are unable to attach the chromosomes, and so the separation of either sister chromatids or homologous chromosomes can't take place.
Metres are exactly 100 cm in length, the easiest way to go from metres to centimetres is to simply add the extra 1 or 2 zeros, so 4.5 metres would be 450 centimetres.
As for the millimetres, 1mm is equal to 0.1cm, once again, just move the decimal forward by one numeral, and you'll have the converted value, making 50mm = 5.0cm.
Your shark would be 450cm long and have teeth with an average length of 5cm.
Answer:
Hydrogen Bonds
Explanation:
In the polymerase chain reaction (PCR) the temperature rises to 90 ° C - 95 ° C, to break the hydrogen bonds, which are the types of bonds responsible for pairing the two strands of DNA, this process is known as denaturation of DNA.
The DNA is extremely stable, due to a large number of bonds (hydrogen bonds) that form between the two strands. If the temperature decreases, these bonds will begin to recompose, until the DNA returns to its original state
