Microevolution - Allele frequency changes in a certain population over an amount of generations, it can also be simply described as "an evolutionary change in populations".
Answer: The 3rd one, answer C
Answer:
Chemical engineering
Explanation: I am not really that good at science but my opinion is that it is chemical engineering because the process of the rock breaking down with the listed factors of water, carbon dioxide etc. If you are not sure you can also look of the definition for each of the engineering factors...
Answer:
Because of homologous recombination
Explanation:
- When genes are establish on different DNAs or far apart on the same chromosome, they are classified self-sufficiently and are said to be unlinked.
- When genes are very close together on the same chromosome, they are said to be linked. That means that alleles, or genetic versions, that are already together on a chromosome will be inherited as a unit more often than not.
- We can see if two genes are linked, and how closely, by using data from genetic crosses to calculate the frequency of recombination.
- Using the technique of discovery recombination happenings for numerous gene pairs, we can make link maps that show the order and relative distances of the genes on the chromosome.
- When the genes are on the same chromosome but far apart, they are classified independently due to crossing (homologous recombination). This is a procedure that happens at the start of meiosis, in which homologous DNAs randomly exchange matching fragments. Crossing be able to connection new alleles in combination on the same chromosome, causing them to enter the same gamete. When the genes are far apart, the crossing occurs with sufficient frequency for all types of gametes to occur with 25% percentage frequency.
- When the genes are very close together on the same chromosome, the crossing still occurs, but the result (in terms of the types of gametes produced) is different. Instead of being classified independently, genes tend to "stay together" during meiosis. That is, alleles of genes that are already together on a chromosome will tend to pass as a unit to gametes. In this case, the genes are linked
Answer: Propionly CoA
Explanation:
During oxidation of odd chain fatty acids, the odd chain are oxidized exactly in the same manner as even chains. However, after successive removal of 2 carbon units, at the end, one 3-carbon unit, propionyl CoA is formed.
Propionyl CoA is a product of beta oxidation of odd chain fatty acids.
In three steps reaction propionyl-CoA can be converted to succinyl-CoA, an intermediate of the citric acid cycle which is converted to oxaloacetate, and is used for gluconeogenesis.
