If two organisms show a developmental homology you would also definitely expect them to share genetic homologies.

Homology is the similarity between two organisms. This similarity can be of body structures, physiology, etc. This homology is generally due to shared ancestral history between two organisms. For example, the wings of a bird and bats are homologous structures, this is because they have a common anatomy.

Genetic homology refers to the arrival from the same gene from a common ancestor. The same gene is shared between two organisms who may not be related in any other matter. Genetic homology can even be depicted by the sequences of a protein.

Circadian rhythm refers to

Answer:

The correct option is B) a pattern of biological functioning that occurs on a 24-hour cycle.

Explanation:

Biological rhythm is defined as the regular variation of an organic function related to the course of time, circadian biological phenomena (around the day), are those with a period of approximately 24 hours.

Circadian rhythms are physical, mental and behavioral changes that follow a daily cycle (the biological rhythm), and that respond primarily to light and darkness in an organism's environment. This cycle close to 24 hours, allows to recognize the sleep-wake phenomena and their homeostatic action, in the systemic processes of every living being. The circadian system is composed of photoreceptors, pacemakers and efferent pathways that allow a regular functioning of the sleep and wakeful state.

A medical study was investigating if getting a flu shot actually reduced the risk of developing the flu. A hypothesis test is pe

weqwewe [10]

Answer:

d. Researchers said the flu shot reduced the risk of developing the flu when it actually didn't.

Explanation:

A Type I Error can be defined as the error that occurs in hypothesis when a researcher rejects the opposite of his hypothesis even though the opposite of his hypothesis is correct or true. Type I Error can also be called a False positive.

In the question above an hypothesis was carried out by researchers to determine if getting a flu shot would reduce the risk of developing a flu.

The truth is " Getting a flu shot actually reduces the risk of developing a flu"

But the researcher hypothesis test result that would result in a Type I error says "Researchers said the flu shot reduced the risk of developing the flu when it actually didn't".

This result of hypothesis test of the researchers above is a rejection of truth (the truth is an opposite of the researchers hypothesis test) and it would result in a Type I Error.
