Crossing over can lead to an abnormal genome if the exchange is not done equally, which can lead to an in-utero death or congenital diseases.
The small intestine receives food directly from the stomach and this is where food is mixed with strong digestive juices from the liver and pancreas
Answer: D) By decreasing the activation energy of a reaction
A catalyst is a substance that speed up the rate of chemical reaction without affecting the product of the reaction. They only affect the rate of reaction not the yield of reaction.
Catalyst provide an alternative reaction pathway that has lower activation energy than that of uncatalysed reaction. It increases the frequency of collision and because of these greater collision which lowers the activation energy of the reaction.

The following describe the inheritance pattern of autosomal genetic disorders.
- For an autosomal dominant disorder to be expressed just one copy of the abnormal allele must be inherited.
- For an autosomal recessive disorder to be expressed, two copies of the abnormal allele must be inherited.
<h3>What is autosomal genetic disorder?</h3>
Autosomal disorders is a form.of genetic disorders which is as a result of mutations in genes on the autosomes or chromosomes. Each person have two copies of autosomal gene, one of the alleles are inherited from each parent. Autosomal dominant disorders occur when there is a mutation in one copy of the gene.
Therefore, The following describe the inheritance pattern of autosomal genetic disorders.
- For an autosomal dominant disorder to be expressed just one copy of the abnormal allele must be inherited.
- For an autosomal recessive disorder to be expressed, two copies of the abnormal allele must be inherited
