Answer:

Evolution is considered a way in which past generations were able to adapt to the difficulties and changes that the world around them imposed, from the need to seek food to survival in the face of different climatic and landscape changes, becoming stronger and therefore allowing the enduring and transcendence of it.

Explanation:

The importance of evolutionary studies is very large, since all organisms and their characteristics are products of evolution. It has an enormous interest applied in topics such as biodiversity conservation, medicine, agriculture, livestock, etc. Evolutionary biology is concerned with understanding the processes that have given rise to the current characteristics of organisms, and explaining why the characteristics of those organisms are what they are and not different ones.

Answer: The answer is option C) two different species on the basis of reproductive behavior

Explanation:

This situation observed in South America is a good example of Sympatric speciation.

Where, two organisms similar in many respects by

- occurring in the same territory, differing ONLY as two different species because they DO NOT interbreed - thus, becoming different species on the basis of reproductive behavior.

So, option C is the answer

magine you are trying to determine the phenotypic ratio of hair color. Brown (B) hair color is the dominant trait and blonde (b)

skad [1K]

Answer:

1:1 (brown:blonde)

Explanation:

Brown hair color (B) is dominant over blonde hair color (b).

Heterozygous parent will have the genotype Bb

Homozygous recessive parent will have the genotype bb.

Crossing hetezygous parent with homozygous recessive parent:

Bb x bb

Progeny: Bb, Bb, bb, and bb.

2 Bb brown hair

2 bb blonde hair

Phenotypic ratio = 1:1 (brown:blonde)

The correct answer is 1:1 (brown:blonde).

Mandarinka [93]

Answer:

Every organism possesses in its ribosome a protein that is similar to rpl4. This protein has an amino acid sequence that is similar to the sequence of E. coli’s rpl4.

Explanation:

Phylogenetic tree is a diagram which represents the similarities between different organisms and shows their evolutionary histories.

The presence of a similar genetic sequence or amino acid sequence shows that the gene is common in all those organisms. This means that all organisms had a common ancestor through which the gene or amino acid was transferred. The genetic r amino acid sequence remained common in all the different organisms.

Marfan syndrome is a dominant trait. A cross between a homozygous dominant and a heterozygote would produce what phenotypic rati

umka2103 [35]

Answer:

The correct answer is- 4:0

Explanation:

Marfan syndrome is a genetic problem which affects the connective tissue in the body. The trait for this disease is autosomal dominant which means even one abnormal copy of this gene in the offspring or individual is sufficient to cause this syndrome.

Let S is the allele that is dominant for this syndrome and s is recessive. So if a cross between homozygous dominant(SS) and heterozygous individual (Ss) occurs than all the offspring would have this syndrome.

S s

S SS Ss

Therefore all 4 offspring would have at least one dominant allele which is sufficient to cause this syndrome. So the phenotype ratio would be 4:0.
