PLSS HELP how is gene knockout similar to gene sequencing?
alexdok [17]

Answer:

Gene knockout is a technique used to determine the function of a gene that has already been sequenced, which is achieved by analyzing the phenotype of the individual carrying the knockout mutation(s). Moreover, gene sequencing is a technique used to determine the sequence of a given gene, which allows to determine how gene variants (polymorphisms) may be associated with the phenotypes of the target trait.  

Explanation:

In genetics, gene knockout is a technique used to trigger mutations in a (already) sequenced gene in order to inactive its function and observe the resulting phenotype for a particular trait. This approach that starts with the inactivation of a given gene and ends with the phenotype is known as reverse-genetics. On the other hand, gene sequencing can be defined as the methodologies/techniques/tools used to determine the nucleotide base pair sequence of a particular gene. The gene knockout technique involves knowing a priori the gene sequence in order to obtain a gene knockout (gene KO). The combination of the information obtained from these techniques can be used to determine how variation (genetic variation) affects the expression of a phenotypic trait.

Select three changes that are examples of physical change.
Marysya12 [62]

Answer:

ice melting

juice freezing

paper folding

Explanation:

The difference between a physical reaction and a chemical reaction is composition. In a chemical reaction, there is a change in the composition of the substances in question; in a physical change there is a difference in the appearance, smell, or simple display of a sample of matter without a change in composition.

If you fill up a balloon with a small amount of air, then set it in direct sunlight, you will see that the balloon expands. This
lakkis [162]

Answer:

Increase in kinetic energy of the gases

Explanation:

The direct sunlight will heat up the molecules making up the gases in the balloon.

Kinetic energy resulting from the heating of these particles will make them become randomized. They then begin to move more haphazardly colliding vigorously with themselves and the wall of balloon.

According to Charles's law "the volume of a fixed mass of gas is directly proportional to its temperature provided pressure remains constant" .

The sunlight heats the balloon and causes a rise in temperature. This will make the gas volume to increase and the balloon expands.
