fish frogs birds and monkeys all have an embryonic stage in which structures called pharyngeal slits appear on the sides of the throat. Based on this information, which of the following is the best conclusion about the evolutionary histories of fish, frogs, birds, and monkeys?a) The animals evolved from a common ancestorb) The animals did not develop lungs for breathingc) The animals are not adapted to eat the same kinds of foodd) The animals have evolved similar developmental rates from fertilization to birth
Repeated branching events, in which new species split off from a common ancestor, produce a multi-level "tree" that links all living organisms. Darwin referred to this process, in which groups of organisms change in their heritable traits over generations, as “descent with modification." Today, we call it evolution.
some fungi obtain their nutrients from a living host (plant or animal) and are called most biotrophic fungi have fairly narrow host ranges—they are specialized on a limited called rhizomorphs that allow the fungus to grow from one tree to another. ascospores are formed inside a sac-like structure called an ascus. so your answer is a
more words for this could be abiotic and biotic
abiotic: living organisms within an ecosystem
biotic: non-living organisms within an ecosystem
