Explanation:

Binary fission occurs in which of the following type of organsim?

Answers

Answer:

A. Prokaryotes like bacteria

Explanation:

Binary fission is a type of asexual reproduction (requiring only one organism, as opposed to sexual reproduction, which requires two) occurs when an organism itself splits into two - hence binary (bi- means two).

Binary fission occurs most often in prokaryotes; eukaryotes like plants and animals engage more in sexual reproduction because they are more complex.

The answer is thus A.

Definitely answer choice a, prokaryotes like bacteria

Scientists often ask questions to clarify data or guide scientific research. What are two scientific questions you have that
could clarify relationships about the DNA or traits of these orchids?

Answers

Answer:What traits would orchids have if the MADS-box genes were not duplicated?

If the genetic mutation changed the shape of the flowers, would pollinators still be attracted to the orchids?

Explanation: The example given by Plato

If the genetic mutation changed the shape of the flowers, would pollinators still be attracted to the orchids.

What is Genetic mutations?

The DNA sequence of a gene is altered to generate a different result, which is known as a genetic mutation. The DNA sequence of that gene is permanently altered.

For humans to develop, which is the process of change over a number of generations, genetic variances are crucial. In one person, a spontaneous genetic mutation takes place.

The genetic mutation of that person is passed down through generations (hereditary) to their offspring. If the mutation increases a person's likelihood of survival or immunity to disease, it starts to be handed down through generations and disseminated throughout the community.

Therefore, If the genetic mutation changed the shape of the flowers, would pollinators still be attracted to the orchids.
