Answer:

light

Explanation:

Light is an important growth factor for plants generally because its energy is utilized for food production during photosynthesis.

When tall trees form a shade over smaller trees, light becomes inadequate for the smaller trees and as such, a limited resources.

Answer:

A-Energy

Explanation:

Plants get their energy from the Sun. So, if taller trees are blocking the Sun, Small trees may not get any Sun and will not have very much energy.

What happens during the initiation step of DNA transcription? A ribosome attaches to the initiation codon of a completed mRNA st

Amanda [17]

Answer:

A portion of the DNA unwinds and RNA polymerase attaches to the DNA within the transcription bubble.

Explanation:

Transcription is the process in which DNA template is used to synthesize mRNA.

There are three steps of transcription:

Initiation

It is the process in which a portion of DNA unwinds and RNA polymerase binds to the promotor region on the DNA.

Elongation

It is the process in which RNA polymerase moves along the DNA template and synthesizes mRNA. During this process, unwinding of double stranded DNA takes place.

Termination

As the RNA polymerase moves along the DNA template, it finally reaches a termination signal and then stops synthesizing. It is followed by the detachment of the newly formed mRNA and RNA polymerase from the DNA.

QUESTION:

A ribosome attaches to the initiation codon of a completed mRNA strand.

This is the incorrect answer choice as this process does not happen in the process of transcription. This event happens in the process of translation in which mRNA is used to synthesize proteins or amino acids. mRNA attaches to ribosome during this process.

RNA polymerase moves along the template strand of the DNA creating an mRNA strand.

This is the incorrect answer choice as this event takes place in the process of elongation.

A portion of the DNA unwinds and RNA polymerase attaches to the DNA within the transcription bubble.

This is the correct answer choice as this event takes place in the process of initiation of transcription

The mRNA detaches from the RNA polymerase as the RNA polymerase leaves the DNA strand.

This is the incorrect answer choice. This event takes place in the event of termination of transcription.

How do transitional fossils help explain the evolutionary steps that took place to produce modem organisms?

lesya [120]

Answer:

Transitional fossils show how a particular taxa accumulated adaptations to fit particular environments and/or ecological niches

Explanation:

Transitional fossils are fossilized remains of taxonomic groups/species that illustrate an evolutionary transition between a known version of a taxa/species and the current taxa/species. Transitional fossils are fundamental because they can be clearly differentiated from the ancestral group as well as of its derived descendant group. For example, there exist transitional fossils known as "mammal-like reptiles"(i.e., therapsids that gave rise to the true mammals), which are clearly different from current mammals.
