This is an example of developmental homology. Studying embryological development of living things provides clues to the evolution of present-day organisms. During some stages of development, organisms exhibit ancestral features in whole or incomplete form. Homologous structures are those structures whose underlying similarity arises from their being derived from a common ancestral origin while analogous structure are those whose similarity comes from their performing of a similar function.

Organism A has blunt teeth, while organism B has sharp ones. Identify the organisms on basis of their feed habit and give anothe

VikaD [51]

Answer:

- Organism A is most likely a herbivore

- Organism B is most likey a carnivore

Explanation:

Based on feeding habit, organisms, usually animals, can be classified into three categories namely: herbivores, carnivores and omnivores.

- Herbivores are those organisms that feed on vegetative matter i.e. plants while carnivores are those organisms that feed on flesh of other animals or organisms. Based on what they feed on, herbivores are adapted to possess blunt teeth (for chewing) like Organism A in this question while carnivores are adapted to possess sharp teeth (for tearing flesh) like Organism B.

Based on the above explanation, organism A is most likely a HERBIVORE while organisms B is most likely a CARNIVORE.

- Another notable point of difference between herbivores and carnivores, which is likely to differentiate organism A and B as well, is that herbivores possess digestive enzyme- amylase in their saliva while carnivores do not. Herbivores need AMYLASE to break down complex carbohydrate (starch) in the plants they feed on.

At a fair or circus, some performers and clowns take long balloons and fold them into animals and objects as toys for children.

mixer [17]

The statement which explains why a balloon can fold, twist, and bend without bursting is: B. The balloon is filled with air, which is a mix of gases. Air is fluid and can move around the inside of the balloon as it is folded.

A balloon can be defined as a flexible rubber bag that can be inflated with a gas such as air.

Generally, air can be trapped in a balloon by sealing its neck tightly.

Hence, this makes it possible for performers and clowns to fold, twist, and bend an inflated balloon into animals and objects as toys for children.

A inflated balloon can be folded without it bursting simply because air is fluid and as such, it would move around the inside of the balloon as it is folded.

In conclusion, air, which is a mixture of gases would move around the inside of the balloon as it is folded because it is also a fluid.

Why are differences and similarities in DNA and proteins evidence of evolution?

olga55 [171]

Answer:

Homologous structures provide evidence for common ancestry analogous structures show that similar selective pressures can produce similar adaptations beneficial features Similarities and differences among biological molecules in the DNA sequence of genes can be used to determine species relatedness
