Explanation:
Cuando los niveles de testosterona están bajos, la hormona liberadora de gonadotrofina (GnRH) es liberada por el hipotálamo que a su vez estimula la glándula pituitaria para liberar LH. Esta última hormona estimula los testículos para sintetizar la testosterona.
Answer:
Few crosses
The complexity of cat genetics
Crosses not controlled by the researcher
Explanation:
The purpose of this question is to determine why Megor Grendel is less famous than that of Gregor Mendel.
Gregor Mendel examined pea plants, which have a number of benefits for deducing genetic rules, including:
- The researcher has total control over the crosses.
- Because the peas have both self and cross-fertilization, it is possible to alter the crosses in the simplest way possible.
- Pea plants may be examined for a greater series of generations than cats or other animals.
- Because plant genetics is not overly complicated, several traits may be investigated at the same period.
As a result, the primary factors why Megor Grendel's experiments are not well-known:
- The presence of only a few crossings: It is impossible to establish a genetic theory with such a small number of crossings on the test subject of the organism.
- Cat genetics is too complicated therefore, the fur gene color on the X-chromosome, a characteristics mosaic inheritance. As a result, It is much too complicated to deduce an inheritance pattern.
- Crossings that the researcher cannot fully control. Unlike plants, crosses in animals cannot be totally controlled by the researcher.
As a result, it is impossible to draw any conclusions from them.
Explanation:
The answer is F...because h2o molecules are heavier than the atmosphere it surrounds. Therefore, gravity takes over. plse correct me if wrong.
because of gravity, h2o is directed down. That's how plants survive, Remember, ..what goes up, must go down...per " isaac newton."
Answer:
This is how cells gene regulation occur.
Explanation:
Regulation of gene expression is very very important thing to maintain the normal levels of all body proteins according to our body"s requirement.
During positive gene regulation enzymes of various metabolic pathways of the target cell is being activated,thus supplying the cellular need of various metabolites and proteins.
During negative regulation various enzymes are turned off thus blocking the formation of metabolites or proteins not required by the cell.
