Answer:
genotype is responsible for establishing phenotype
Explanation:
When Mendel experimented with pea plants, concept of genes and alleles had not come up yet. Through his experiments Mendel first proved that some type of combination in cells leads to a particular phenotype.
He coined the term "factors" which are today known as alleles. These factors paired up and displayed a particular phenotype. Today we know that the alleles are responsible for a genotype which ultimately results in a phenotype. Hence, he established that genotype is responsible for establishing phenotype even before the term genotype was coined.
Answer:
The Buffalos carrying capacity would most likely go down if the water supply increases.
Explanation:
If water supply increases Buffalos would have easier access to water. example: instead of getting new water every month or so when it rained they can get water anytime due to the increased supply.
Edwin Hubble's observation of galaxies revealed that the light received from them were red-shifted, indicating that they are moving away from us. And the seemingly farther away a galaxy was, the greater its red-shift. This can only be explained if a all the galaxies were expanding outward. Determining the exact distances to the other galaxies was a problem, however, until the Hubble space telescope. It had high enough resolution to identify Cepheid variable stars in other galaxies, and accurately determine their distance, and therefore the expansion rate of the universe. Hope this helps!!
Answer:
The correct answer is option e.
Explanation:
X-rays refers to the ionizing radiation exhibiting shortest wavelengths and possessing the tendency to pass through the tissues. This tendency of passing through the tissues on getting exposed to X-rays even for brief duration will lead to displacement of electrons from the orbital of molecules and atoms like witnessed in chromosomes.
X-rays are not stable and possess high energy and when this energy passes on to the electrons, it gets displaced resulting in the modifications of the structure of nucleic acid bases in the DNA resulting in chromosomal modifications like inversion, transversion, duplication, and deletion mutations.
Answer:
The differences arise because it actually takes the Earth around 365.25 days to make a full orbit. This value is rounded down for the sake of our timekeeping.
