Answer:

The TATA box helps bind the <em>RNA polymerase</em> in the correct place.

Explanation:

The TATA box can be found before a gene. It is type of promoter sequence which allows for the process of transcription to begin.

The transcription factor proteins recognize the TATA sequence and bind to it. The RNA polymerase is positioned by the transcription factor proteins. The transcription factors form a binding site for the RNA polymerase which binds to the specific site and starts with the transcription process.

A key prediction/implication of evolutionary theory is that:

Valentin [98]

Answer:

-all species change gradually over time.

Explanation:

Mutation often results from cell replication and division. These occur as small, random, errors within the genetic code that become more common or stable within a population over time as traits.

As organisms live within varying niches, environmental changes may render some genetic traits obsolete. However, others may become more beneficial as an adaptation. These adaptations, which make an organism and its offspring suited to a niche, and more likely to survive and reproduce become inherited- this process is called evolution.

Trace the flow of energy through a typical food chain (describing "what eats what"), including the original source of that energ

tester [92]

Answer:

The answer is given below:

Explanation:

A food chain consists of producers and different consumers. Producers are the organisms which produces food using sun energy. Consumes directly eats plants or eat other animals to fulfill their energy needs. So, in any ecosystem energy flows through food chain in unidirectionl manner.

Sun is the ultimate source of energy. The producers uses solar energy to make chemical energy (glucose) through photosyntheis. The cosumers use this chemical enegy through food by eating plants. Some animals eat other animals to get energy. The chemical energy stored as ATP (an energy currency).

saw5 [17]

The designs of Pasteur and Redi’s experiments were different such that Pasteur was able to show spontaneous generation was false, but Redi was not and is denoted as option C.

<h3>What is an Experiment?</h3>

This can be defined as a procedure which includes series of methods done to accept or refute a hypothesis or to ascertain its authenticity. Spontaneous generation is a theory which states that living organisms could arise from non living matter.

Pasteur experimented with broth while Redi experimented with rotten meat and Pasteur was able to confirm the micro-organisms in the air which disproved the concept of spontaneous generation and thereby making option B the most appropriate choice.

in eukaryotes, genetic material is packaged in the nucleus. which group accurately lists the levels of the packaging in order of

vredina [299]

The DNA molecules are often fitted into the nucleus through packaging into a compressed and compact structure. The group that accurately lists the levels of the packaging in order of increasing size are nucleotide, DNA duplex, nucleosome, chromatin, chromosome.

Chromosomal DNA is often packaged into a nuclei that is microscopic in nature through the help of histones.

In the DNA packaging inside the nucleus, the cells folds or wrap their DNA strands around scaffolding proteins to form a coiled condensed structure. The structure is known as chromatin.

The full question is below

Which one of the following MOST accurately lists the components in order of increasing size?

A. chromosome, chromatin, nucleosome, DNA duplex, nucleotide

B. nucleotide, DNA duplex, nucleosome, chromatin, chromosome

C. nucleotide, DNA duplex, chromatin, nucleosome, chromosome

D. nucleotide, nucleosome, DNA duplex, chromatin, chromosome

E. chromosome, nucleosome, chromatin, DNA duplex, nucleotide
