A researcher is using the pUC18 vector to introduce a human gene into bacteria. He exposes bacteria to this recombinant molecule

and then grows these organisms in culture. He is very surprised to find that all of the resulting bacterial colonies are blue and survive treatment with antibiotics. What can he conclude from these results?

Answer:

The results from this experiment conclude that all of the resulting bacteria contain the pUC18 plasmid without the human gene.

The method of genetic engineering might seem very easy but in actual it is a very difficult task and most of the time a person won;t get the expected results. The chances of a vector to actually take up a recombinant DNA are very less. Even after this, the chances of a recombinant plasmid to enter a bacterial cell by transformation are very few.

xz_007 [3.2K]

Answer:

No, coyote will not become the apex predator.

Explanation:

No, coyote will not become the apex predator but greatly reduces the populations of foxes in order to reduce competition for available resources. Yes, The coyote population will decreases because t he gray wolf kills coyote to avoid competition for food resources. If another wolf is introduced to fit the same ni che, the coyote population will decrease because the wolf feeds on coyote. As the number of coyotes increase, the number of beavers will decrease because coyote feeds on beaver. If the gray wolf became extinct,  the coyote population increases in that location due to no predator.

1. Do these results support the claim that application of the jewelweed is a good treatment for symptoms caused by poison ivy? E
-Dominant- [34]

A claim is an unverified statement or theory which is made about something which may or may not be true.

<h3>Verification of a claim</h3>

For a claim to be validated, i.e, proven to be true (in science), then there needs to be tests and experiments which needs to be carried out to show that the claim is valid.

With this in mind, if for example if there's a claim that jewelweed helps to treat symptoms caused by poison ivy, then there needs to be a controlled experiment to see if this is true or not.

If after a series of experiments and it can be established without any iota of doubt, then the claim is valid and the scientific process will move to the next stage.

Please note that your question is incomplete so I gave you a general overview to give you a better understanding of the concept.

Which term describes body structures in different organisms that have different outward appearances but develop from the same em
Nataly [62]

Answer:

The correct answer would be B) homologous.

Homologous organs refer to the set of organs which have different appearance and function but share common anatomy due to common ancestry.

For example, the forearm of human, forelimb of the horse, wing of a bat, wings of birds, and seal's flipper share common underlying anatomy.  They are made up of same sets of bones (humerus, radius, ulna, carpels, metacarpals, and phalanges).

These organs are adapted to perform different functions in an environment.

It is also observed that these organs developed in the same manner in the embryo and from similar origins.
