Answer:

Prokaryotes only contain three different promoter elements: -10, -35 promoters, and upstream elements. Another main difference between the two is that transcription and translation occurs simultaneously in prokaryotes and in eukaryotes the RNA is first transcribed in the nucleus and then translated in the cytoplasm.

Answer:

Answer below

Explanation:

Well when natural selection occurs, genes that don't benefit the speicies, or more accurately, harm it by ruining camoflague. Natural selection can result in one creature evolving into 3 different species when those creatures get put into different environments that promote genetic mutations that help them survive. After a long while of genetic mutations coming and going to adapt to their environment, those three members of the species are no longer the same species because they've all adapted to different environments.

Answer:

The answer is the flexibility of DNA.

Explanation:

The flexibility os DNA is what allows transcription factors at distant binding sites to do their job. The DNA loops like cooked spaghetti to bring far-off binding sites and transcription factors close to general transcription factor or mediator proteins.

Which diagram shows the pathway of energy through an ecosystem?

Iteru [2.4K]

Question 1:
The correct answer should be the one that shows the producer first, (->) followed by the herbivore, (->) with the carnivore last.
Producers are organisms that harvest their own 'food' using things like the sunlight and water. Examples of producers are grass and other vegetation.

$Producer$
The herbivore, or an organism that consumes only vegetation and/or algae, consumes the producer.

$Producer$ ⇒ $Herbivore$
The carnivore consumes meat, or other animals such as the herbivore. It's the last.

$Producer$ ⇒ $Herbivore$ ⇒ $Carnivore$
Therefore the answer is B.

Question 2:
I'm pretty sure that succession as well as regrowth after volcanic eruption (Just look at Mount St. Helens. After 30-35 years after the eruption, nature is still recovering) happens over time/slowly. I would say global warming [C](?) would be the answer.

Answer:

Glucose: is a simple sugar which is an important energy source in living organisms and is a component of many carbohydrates.

Fructose: or fruit sugar, is a simple ketonic monosaccharide found in many plants.

Deoxyribose: sugar derived from ribose by replacing a hydroxyl group with hydrogen.

Ribose: is a kind of sugar that is produced by the body. It is used as a medicine. Ribose is used for heart disease, mental function, athletic performance, chronic fatigue syndrome (CFS), fibromyalgia, and many other conditions, but there is no good scientific evidence to support these uses.

Glyceraldehyde (glyceral) is a triose monosaccharide with chemical formula
