Answer:

Yes, it is estimated that there are about one trillion microbes species on earth, and we have not been able to isolate 99.99% of them, so, the knowledge is very limited. There is an study approach called METAGENOMICS.  In Greek, meta means “transcendent.” It is a research field that allows to study comunities from their total DNA. It is, you can extract and sequence DNA from a sample, and find out about the composition of the population in there, even the interactions between them, with no need of pure culture.

Answer:

Organisms need 6 things to be considered living which are, responsiveness to the environment, the ability to reproduce, having a metabolism, being able to breathe, maintaining homeostasis, being able to pass down traits, and made of cells. Cars, do not have the ability to reproduce, do not maintain homeostasis, cannot pass down traits, do not have a metabolism, etc... a living being needs to fit all of the criteria to be considered living. In this case, cars do not fit the criteria.

Knowing this, you would tell the alien about the 6 things needed to be considered a living being. After that, you would tell the criteria that the car does not fit which would then explain how a car is in fact, not a living being.

svlad2 [7]

Answer:

CGUAUGUCA

Explanation:

Firstly, the strand in the question is a DNA strand because it contains the Thymine base, which is only found in a DNA molecule. The process of changing a DNA molecule into RNA molecule (specifically a messenger RNA) is called transcription. Transcription is done using the complementary base pairing rule, which states that Adenine (A) will always pair with Thymine (T), and Guanine (G) will always pair with Cytosine (C).

In the case of transcription, the Thymine bases will change to Uracil (U), since Uracil is only found in the RNA molecule. That is, A-U and G-C. Hence, a DNA strand that reads: GCATACAGT will produce a mRNA strand CGUAUGUCA.

If a hormone is released into the bloodstream and therefore comes into contact with many cells, what determines which cells in t
g100num [7]

Answer:

THE CELL RECEPTOR DETERMINES WHICH CELL RESPOND TO AN HORMONE.

Explanation:

In the endocrine system, the hormones are usually released into the blood stream from where they traveled to their target organs. Even though the hormones meet a lot of cells on their way, they do not bind with just any cell. Hormones bind specifically to cells that have receptors that is meant specifically for the hormone. The cell receptor enables the binding together of the hormone and the cell membrane or the cell surface. After the binding, the hormone then elicit the needed response in the cell.
