3. Break down food so nutrients can be absorbed
Explanation:
the reasoning is when you digest something your body is breaking down the food into small chuncks so that the nutrients can be absorbed easier

What Are Alleles? Where Do alleles come from?
Answers
Answer:
An allele is one of two more versions of a gene. An individual inherits two alleles for each gene,one for each parent.
Explanation:
Part-1
An allele is a variant form of a gene. Though the term allele was originally used to describe variation among genes, it now also refers to variation among non-coding DNA sequences.
For example: an allele is the gene that determines hair color.
Part-2
One allele for every gene in an organism is inherited from each of that organism's parents.

what is the effect of Dideoxycytidine on the replication of viral DNA.
Answers
Answer:
Several 2',3'-dideoxy-3'-thiapyrimidine nucleosides were studied for their ability to inhibit hepatitis B virus (HBV) DNA replication in a HBV-transfected cell line (2.2.15). 2',3'-Dideoxy-3'-thiacytidine (SddC) and 5-fluoro-2',3'-dideoxy-3'-thiacytidine(5-FSddC) were found to be the most potent anti-HBV compounds of those examined. Both compounds resulted in nearly complete cessation of viral DNA replication at 0.5 microM, as monitored by the absence of both intracellular episomal and secreted viral DNAs. The HBV-specific RNAs were not reduced at concentrations that completely blocked HBV DNA replication, suggesting that the inhibitory target is HBV DNA synthesis. The antiviral action of SddC and 5-FSddC was reversible. The concentration of SddC and 5-FSddC required to inhibit 50% of 4-day cell growth in culture was 37 microM and more than 200 microM, respectively. Unlike 2',3'-dideoxycytidine, these two compounds do not affect mitochondrial DNA synthesis in cells at concentrations lower than that required to inhibit cell growth. In view of the potent and selective antiviral activity, both SddC and 5-FSddC should be further evaluated for the treatment of human HBV infection.

Explanation:
There are 20 naturally occurring amino acids, therefore, there are only 20 mRNA codons. True or false
Answers
Answer:
False. There are 20 amino acids, but 64 possible codons.
Explanation:
Genetic information for the aminoacids assembly during the protein synthesis is stored in short sequences of three nucleotides named codons in the mRNA. Each of the codons represents one of the 20 amino acids used to build the protein. The total number of possible codons is 64, from which 61 codify amino acids -more than one codon codify for the same amino acid-. One of these amino acids is also the start point of protein synthesis. And the left three codons are stopping translation points.
The codons indicating the initiation or stop points during the translation process are:
• The start codon AUG is the most common sequence used by eukaryotic cells and places near the 5´extreme of the molecule. However, other codons might be used as well. Prokaryote cells might use the codons GUG or UUG.
• The end codons are UAA, UAG, UGA.

Answers
In the blood group systems, the phenotypes largely depend on the genotype.
A phenotype is an observable trait of an organism, which depends on the genotype, environment, or both.For example, the blood group system ABO is dependent on the presence of certain antigens on the surface of blood cells.In this system, A and B are codominant alleles, whereas O is recessive and therefore it is not expressed in heterozygous individuals.In conclusion, in the blood group systems, the phenotypes largely depend on the genotype.

In the blood group system, the concept of Co-dominance is applied, where the phenotypes depend on the genotypes.
What do you mean by Phenotypes?Phenotypes may be defined as the appearance or the manifestation of characters. Phenotypes are also known as traits.
Co-dominance is a condition where both alleles in heterozygous conditions give visible expression. ABO blood group system in humans depends on certain antigens on the surface of blood cells. Alleles A and B are co-dominant while allele O is recessive.
Therefore, in the blood group system, the concept of Co-dominance is applied, where the phenotypes depend on the genotypes.

Como se chama a transferencia de enrgia termica flui de um corpo com maior temperatura quando ao outro de menor temperatura quando ha diferença de temperatura entre ambos
Answers
Answer:
Conduction.
Explanation:
Conduction is the process in which heat energy is transferred from the hotter body towards colder body because of temperature difference between two bodies. Conduction occurs only due to physical contact between two bodies. In the conduction process, the thermal energy flows from a body with a higher temperature to the other body having lower temperature until both bodies having same temperature.
