The biological evolution is the alteration in the features of an organism’s population over inherited generations. These features are due to the gene expressions that are distributed from parent to progeny throughout the reproduction. The different features are inclined to occur within any population as a consequence of genetic recombination, mutation and other sources of

Answer to Problem 1TQ
The two different organisms are closely associated evolutionarily, then they will share a recent common ancestor. Therefore, option (b) is correct.
Explanation of Solution
Justify the reasons for the correct statement:
In evolutionary biology, the common descent explains how a group of organism shares a common ancestor. The various resemblances between the organisms are mainly due to the information of the organism that are evolved through a common descent from a common ancestor. The two dissimilar organisms which share a more recent common ancestor are most closely associated.
Option (b) is given as, “share a recent common ancestor”.
Hence, the option (b) is correct.
Justify the reasons for the incorrect statements:
Option (a) is given as, “be similar in size”.
The organism that is closely related evolutionary would not be similar in size. Hence, it is a wrong answer.
Option (c) is given as, “have very different DNA sequence in their genes”.
If the organisms are closely related to evolutionary, then it does not contain different sequence of DNA in their genes but is shares a common ancestor. Hence, it is a wrong answer.
Option (d) is given as, “be randomly located throughout the world”.
The two various organisms which are associated evolutionary does not randomly situated all over the world, but it shares a common ancestor. Hence, it is a wrong answer.
Hence, options (a), (c), and (d) are incorrect.
Therefore, if the two dissimilar organisms which shares a common ancestor because it is closely related to the evolution.

Affected individuals show spots of abnormal skin pigmentation and non-cancerous tumors that can interfere with the nervous system and cause blindness. Some tumors can convert to a cancerous form. i The recessive form is a normal protein - in other words, no neurofibromatosis.moovi A typical pedigree for a family that carries neurofibromatosis is shown below. Note that carriers are not indicated with half-colored shapes in this chart. Use the letter "N" to indicate the dominant neurofibromatosis allele, and the letter "n" for the normal allele.

Aerobic respiration of one lipid molecule. The lipid is composed of one glycerol molecule connected to two fatty acid tails. One fatty acid is 12 carbons long and the other fatty acid is 18 carbons long in the figure below. Use the information below to determine how much ATP will be produced from the glycerol part of the lipid. Then, in part B, determine how much ATP is produced from the 2 fatty acids of the lipid. Finally put the NADH and ATP yields together from the glycerol and fatty acids (part A and B) to determine your total number of ATP produced per lipid. Assume no other carbon source is available. 18 carbons fatty acids 12 carbons 9 glycerol A. Glycerol is broken down to glyceraldehyde 3-phosphate, a glycolysis intermediate via the following pathway shown in the figure below. Notice this process costs one ATP but generates one FADH2. Continue generating ATP with glyceraldehyde-3-phosphate using the standard pathway and aerobic respiration. glycerol glycerol-3- phosphate…arrow_forward
