Answer:
XXY and autism, heart disease are some of the characteristics found
Answer:
D. changing the DNA of a living thing to change its characteristics.
Explanation:
Genetic engineering is the process of using recombinant DNA (rDNA) technology to alter the genetic makeup of an organism. Traditionally, humans have manipulated genomes indirectly by controlling breeding and selecting offspring with desired traits.
Hello. You have not informed the experiments to which the question refers, which makes it impossible for hypotheses to be formed. However, I will try to help you in the best possible way.
A hypothesis is an assumption, that is, it is a statement that the researcher believes to be true in relation to the research results, which can be proven or denied when the experiment is finished and the conclusions are established. Therefore, you must make assumptions about the results of the experiment, based on your primary visualization of them.
Human height is one of the traits that belong to traits that cannot easily be placed in discrete phenotypic classes (there is not only tall and short people, there is continuous variation of height between them). Such traits are usually controlled by more than one gene (polygenic traits).
On the other hand, a Mendelian trait is controlled by a single locus.
At resting potential, sodium and potassium molecules may most easily pass through the plasma membrane of a nerve cell.
Discussion:
- The two cations can pass through the gradient of concentration thanks to the potassium and sodium permeability channel that are present in the cell. However, potassium leakage channels are much more prevalent in neurons than sodium leakage valves. Because of this, potassium disperses within the cell far more quickly than sodium seeps in.
- K+ ions build up inside the cell while the membrane is at equilibrium as a result of a movement of molecules with the solute concentration.
- By elevating the concentration of cations in the extracellular fluid relative to those inside the cell, the negative resting membrane potential is established and sustained (in the cytoplasm).
