Answer:
because both balloons have the same charge and are repelling against each other.
Explanation:
because the static charge coming off the balloons is pushing the balloons away from each other
A Student charges two balloon and hangs them side by side. because both balloons have the same charge and are repelling against each other.
What is Balloon?A balloon is a stretchy bag that can be filled with helium, hydrogen, nitrous oxide, oxygen, or air.
Balloons can be filled with smoke, liquid water, granular media (such sand, grain, or rice), or light sources to perform certain jobs.
Modern balloons can be found in a wide range of colors and are produced from materials like rubber, latex, polychloroprene, or a nylon fabric. Early balloons, like the pig bladder, were occasionally fashioned of dried animal bladders.
Therefore, A Student charges two balloon and hangs them side by side. because both balloons have the same charge and are repelling against each other.

There are 20 naturally occurring amino acids, therefore, there are only 20 mRNA codons. True or false
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.

using information about phenotypes
and genotypes in blood group
genes.
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
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.

Which of these is an example of an environment in which natural selection would not occur?
Group of answer choices
A. There is genetic diversity in the population due to mutation and/or sexual reproduction.
B.All offspring have the same chance of survival.
C. Offspring inherit beneficial and detrimental traits from parents.
D. Some offspring have a physical trait that helps the organism compete more successfully.
An example of an environment in which natural selection would not occur is a place where all offspring have the same chance of survival. Thus, the correct option for this question is B.
What is Natural selection?Natural selection may be defined as a type of strategy or process in nature through which organisms particularly gets better adapted to their environment and tend to survive and reproduce more than those less adapted to their environment.
Genetic diversity always favors the process of natural selection to occur. And this genetic diversity is generally induced by evolutionary forces like genetic drift, mutation, migration, etc.
Apart from this, offspring inherit beneficial and detrimental traits from parents and offspring have a physical trait that helps the organism compete more successfully and are also more prone to natural selection.
Therefore, an example of an environment in which natural selection would not occur is a place where all offspring have the same chance of survival. Thus, the correct option for this question is B.

Which statement describes the proper procedure for identifying an organism by using a dichotomous key?
Explanation:
A dichotomous key is a tool that allows the user to determine the identity of items in the natural world, such as trees, wildflowers, mammals, reptiles, rocks, and fish. Keys consist of a series of choices that lead the user to the correct name of a given item. "Dichotomous" means "divided into two parts".
