DNA being placed with DNA polymerase and nucleotides and resulting in new copies is not an opinion or inference because the fact is, new more DNA was found in the test tube after adding the enzymes and nucleotides than before the addition. DNA sequencing of the new copies would have shown that the sequences of the new DNA are identical to the original DNA that was first placed in the test tube. Also, other experiments would have shown that adding other different kinds of molecules or enzymes does not, in fact, produce new strands of the original DNA, nor should it be able replicate the DNA at all.
<h2>Depending on the organism, these needs may include: air, water, nutrients, food, light, shelter, space, certain temperatures, etc. Plants need soil, nutrients, sunlight, water, space, air and appropriate temperatures to survive. Animals need food, water, shelter, oxygen, space and appropriate. You can write: Organisms need air, water and food from their environment. I hope this helps you! </h2>
Answer:
More info given below.
Explanation:
This attraction occurs as a result of static charge. You see an atom is referred to as the smallest particle of a substance; and when an atom gains or looses electrons it becomes unstable creating a difference in potential. However in this case rubbing induces friction which induces heat. This heat excites the atom to loose electrons creating a negative charge on the silk and a converse positive charge on the pencil.
Answer:
Explanation:
Science is the study of the nature and behaviour of natural things and the knowledge that we obtain about them. A science is a particular branch of science such as physics, chemistry, or biology. Physics is the best example of a science which has developed strong, abstract theories.
Five key descriptors for the scientific method are: empirical, replicable, provisional, objective and systematic.
Answer:
Herbivore that feeds on producers
Explanation:
The producers are plants at the bottom of the food web. These are eaten by herbivores, that are the primary consumers.
Herbivores themselves are consumed by carnivores, which are secondary consumers.
Sometimes, these carnivores can be consumed by top predators, like a shark, snake or eagle.
<u>Options and why they are right/wrong</u>
Carnivore that feeds on producers - carnivores do not feed on producers
Herbivore that feeds on producers - this is correct
Herbivore that feeds on primary consumers - primary consumers are animals and herbivores do not eat animals
Carnivore that feeds on primary consumers - this would be a secondary consumer
