Answer:
My answer to the question is "birds migrating south".
Answer:
The answers are :
Explanation:
A. Hidrolyisis- deficient RAS mutant :1. Continual activation of the MAP kinase pathway even in the abscence of signaling molecule, 5.Change in the expression of genes in the absence of the appropriate signaling molecule
C. High GDP affinity RAS mutant: 2.Failure to activate MAP kinase pathway following ligand binding to receptor kinase, 6. Target genes are not expressed even in the presence of signaling molecule
B. Neither: 3. Failure of receptor kinase to dimerize in the presence of ligand, 10. A continuously activated receptor in the absence of ligand
<span>C.)The average rate at which a mountain range rises each year is used to estimate how long ago the range began to rise.
Since geological time and movement takes place over a huge amount of time, most geologist measure the geological time by taking the average rate of almost all the sample and compare. </span>
<em>You will find the cell in metaphase and the draw of the gametes in the attached files</em>
Answer:
Gametes: RY, RX, rY, rX
Explanation:
During metaphase I, homologous pairs migrate to the equatorial plane, where they randomly aline with their kinetochores facing opposite poles. The random arrangement of tetrads is different in every cell going through the meiosis process. There is no equal alinement between two cells. When tetrads aline in the equatorial plane, there is no predetermined order for each of the homologous chromosomes of each tetrad to face one of the poles and then migrate to it while separating. Any chromosome of the homologous pair might face any of the poles and then migrate to it. Each of the chromosomes has two possibilities for orientation at the plane.
During metaphase II, when the new haploid cells are formed, the number of variations in each cell is also different and depends on the chromosomes that form that cell. This random order in the equatorial plane is what introduces variation into the gametes. It is almost impossible that two gametes resulting from meiosis will get the same genetic charge.
Diploid cell) RrXY
Gametes) RY, rY, RX, rX
The alleles of each of the genes randomly migrate to different poles and combine with the allele of the other gene that migrated to the same pole.
Answer:
True.
Explanation:
Conduction is a heat transfer method. The heat passes by direct contact between two objects. The heat will go from the object with the higher temperature to the one with the lowest one. We call this temperature gradient. If we analyze the molecular aspect of conduction, we can see that the molecules with higher temperatures have more energy so, they move more. These molecules will collide with the molecules of the other object transferring their energy. As a result, heat passes from the hottest object to the cooler one till the two substances are at the same temperature, there is thermal equilibrium.
