Its' base can vary. The sugar (deoxyribose) stays the same. And the phosphate also stays the same. There are four different bases. The arrangement of the bases in threes are called condons. These code for amino acids. These make proteins which make us what we are. The codes are also called genes.

If someone told you that plate tectonics is just a theory and that it hasn’t been accepted as a law yet, how would this informat
ch4aika [34]

Answer: There are few ‘laws’ in science. Those ‘laws’ are so named for historical reasons, but they are theoretical in nature. They set out what happens when a theory is applied in practice. A theory is simply the best explanation we have for understanding why some process takes place and predicting what the result will be.

Explanation: Anyone who describes something as “just a theory” does not understand what a theory is. Laws are arbitrary human rules. Theories are severely tested and re-tested explanations of why things happen in the real physical world and can be used to make predictions about outcomes.

Some would say that theories are about why something happens and laws (in science) describe what happens. But this simply makes a scientific ‘law’ a subset of a scientific theory, explaining how to make predictions.

Can someone please help me with 1 evolution question ?
geniusboy [140]
Antibiotic resistance is a consequence of evolution via natural selection. The antibiotic action is an environmental pressure; those bacteria which have a mutation allowing them to survive will live on to reproduce. They will then pass this trait to their offspring, which will be a fully resistant generation.

Use the following graph of two theoretical populations (species A and B) to answer the following questions:
avanturin [10]
A) This is predator-prey relationship.

B) Species A is prey and species B is predator.
- If prey population decreases in number, the predator population will also decrease because there is not enough food for predators to survive and vice versa.

- If predator population decreases, the prey population will increase because less prey will be eaten by predators and vice versa.


C) Let population A be Zebras, and population B Lions.

From the graph, at the beginning the there is increase in Lions, as well as in smaller rate in Zebras. At one point, the population of Lions begins to decrease, so they will eat less Zebras. This will allow Zebras to increase population. With more Zebras on the menu, more Lions will eat and increase their chance to survive. This leads to decrease in Zebra population. But again, with less Zebras, the Lion population must decrease allowing Zebra population to increase, and so on.
