Answer:

1. Evolution can be defined as the gradual development of an organism creating diversity.

2. A common misconception is that Homosapiens are descendants of Apes.

3. analogous structures are features of different species that are similar in function, but not necessarily in structure; such as bird wings and insect wings. homologous structures, however, is an organ or bone with similar underlying anatomical features found in different animals; such as the arms of primates.

4. vestigial structures are structures that have no apparent function and appear to be residual parts from a past ancestor, such as wings of flightless birds.

5. Embryology supports the theory that organisms have a common ancestor in accordance to the theory of evolution.

Scientists can use mutants to study metabolic pathways. These organisms have a mutation in a gene encoding a metabolic pathway e

lisabon 2012 [21]

Answer:

Pyruvate kinase

Explanation:

Yeasts convert glycerol and sugars into glyceraldehyde 3-phosphate (G3P) through independent pathways. Then, G3P forms pyruvate and, in some circumstances, pyruvate is converted in ethanol, which can be used as energy sources. If the mutation affects any reaction before G3P formation, it will only affect yeast growing either on sugar or pyruvate but not both.

Pyruvate kinase is the only enzyme on the list acting after G3P is formed and before pyruvate is formed. All other options are enzymes acting only in the formation of G3P from sugars. Meaning that only pyruvate kinase mutants will lack the ability to grow on both sugars and glycerol.

A mating between a male donkey (2n = 62) and a female horse (2n = 64) produces sterile mules. why are mules sterile?

kirza4 [7]

The horse and donkey, though closely related by sharing a common ancestor, are different species. They have different number of chromosomes hence pairing of homologous chromosomes during fusion of gametes becomes complicated. The mule will have an extra chromosome from the horse hence will have abnormalities such as sterility. A Mule is unable to reproduce due to this same phenomenon. Homologous chromosomes are not well paired for meiosis I.
