Colt1911 [192]

Scientific theories are not absolute and unquestionable truths: they are the best explanation of the data, but they can be challenged if new data is discovered or if a new theory is found that fits to and explains the data even better!
The best answer is d: this is not an accurate description of a scientific theory!

If a polynomial function f(x) has roots 4-13i and 5, the factor of f(x) must be_______.

labwork [276]

So the problem ask to choose among the following choices that has the factor of f(x) if a polynomial function f(x) has a roots 4-13i and 5, base on that, the answer is not in the choices, base on my computation, the answer is f(x) = (x-y+13i)(x-5), I hope you are satisfied with my answer

List the functions of proteins in the text area below.

Wittaler [7]

Answer: 1- Maintenance of oncotic pressure: prot. are macromolecules that hydrate in the plasma and exert a PO retaining water in the vascular medium, all prot. mainly albumin

2- Buffer role: all prot. Plasma acts as a buffer because of their hydrophobic character thus participating in the regulation of acid-base balance

3- Transport function Albumin.Tyroxine binding protein (TBP), transferrin, apoproteins..etc.

4- Enzymes and coenzymes: renin, orosomucoid (coenzymes of LPL)

5- Role in coagulation and fibrinolysis: fibrinogen, thrombin. antithrombin

6- Role in immunity: Ig (lgA JgG.lgM) and complement proteins

7- Role in the allergic: IgE and complement fractions

8- Role in inflammation: α1 antitrypsin, orosomucoides .cerulioplasmin, cytokines, CRP

9- Hormonal role: insulin, glucagon, pituitary stimulins (TSH, FSH, LH)

10- And finally a structural role (such as actin or tubulin that participate in the architecture of the cell, the keratin that makes

What alternate form of genes do nucleic acids have that allows them to offer variability allele codon nucleotide chromosome

Y_Kistochka [10]

Answer:

The options to this question are:

A) allele

B) codon

C) nucleotide

D) chromosome

The answer is A) allele

Explanation:

RNA and DNA are the two nucleic acids in living organisms used for transferring and storing genetic information. Deoxyribonucleic acid (DNA) is the genetic material in living organisms that contains segment coding for useful products/proteins and transmits genetic information from one generation to another. These segments are called GENES.

However, genes contain an alternate form responsible for genetic variation in the traits coded for by them. These alternate or variant form of a gene is called ALLELE. In a diploid organism like human, each trait is encoded by genes which contain contrasting pair of alleles that allows variation for that particular trait i.e. two alleles for each gene. For example, height trait in humans are encoded by gene, which possess two alleles; one coding for short variety (t) and the other for tall variety (T).
