Answer:
Scientists mostly gain new knowledge through direct observation and applying the scientific method. They would start with a hypothesis and test it, then change it or confirm it. Others would test their confirmation from one point, while the third group would test what the second said. And so on and so forth.

Explanation:
In eukaryotic cells, the centrioles are small sets of microtubules composed of tubulin proteins. Moreover, in animal cells, a centrosome is an organelle localized near the nucleus which contains a pair of centrioles. These organelles (centrosomes) are referred to as microtubule-organizing centers. During Anaphase, centrioles move to opposite sides in the cell in order to organize the spindle fibers and separate the chromosomes during cell division.
Answer:
Millions of years ago, the Appalachians were taller than the Himalayas! Millions of years of erosion, however, have taken their toll. ... The crust that is now the Appalachians began folding over 300 million years ago, when the North American and African continental plates collided.
Answer:
17
Explanation:
In corn,
Smooth kernel (S) is dominant to rough kernel (s)
Purple kernel (P) is dominant to yellow kernel (p)
Since no information has been given about the cross here let us assume it to be a standard dihybrid cross.
The phenotypic ratio of dihybrid cross is 9:3:3:1. 9/16 will show dominant phenotype for both traits, 3/16 will show dominant phenotype for one trait, other 3/16 will show dominant phenotype for the second trait, 1/16 will have recessive phenotype for both the traits.
Here,
Purple rough (P_ss) = 52
Yellow smooth (ppS_) = 50
Both of them show dominant phenotype for one trait so they each form 3/16 of the progeny.
If the total progeny was z, 3/16*z = 50
z = (50*16)/3 = 267
Total progeny = 267 kernels
Yellow rough kernels (ppss) = (1/16*267) = 17
So approximately 17 corn kernels will be yellow and rough.
