In nondisjunction, if members of a pair of homologous chromosomes do not move apart during meiosis I or sister chromatids fail to separate during meiosis II, this means one gamete receives 2 of the same kind of chromosome and i<span>f either one of these abnormal gametes unites with a normal one at fertilization, the zygote will also have an abnormal number of particular chromosomes; which is known as an aneuploidy.</span>
Answer:
The differences arise because it actually takes the Earth around 365.25 days to make a full orbit. This value is rounded down for the sake of our timekeeping.
Explanation:
<u>ANSWER:</u>
"Reduced concentration of substrate" available can interfere with the "ability of an enzyme" to catalyse a reaction. The main use of enzymes is to increase "the rate of reactions".
<u>EXPLANATION:</u>
- There are several factors that have an impact on the ability of an enzyme to catalyse a reaction.
- These include temperature, pH levels, and the quantity of substrate as well as the reactant. When the "substrate concentration increases", the rate of the reaction also increases in the presence of an enzyme.
- On the other hand, when the "substrate concentration is low", the enzyme cannot catalyse the reaction at a fast rate.
Answer: Arteries
Explanation: Arteries carry oxygenated blood away from the heart. Except the pulmonary arteries which carry blood to lungs for oxygenation.
Answer:
Dissociate, a decrease in pH
Explanation:
Strong acids dissociate 100% in aqueous solution, and lower pH
