Answer:
0%
Explanation:
This question involves a single gene coding for tail length in a breed of dog called Corgis. The allele for short tail (S) is dominant over the allele for long tail (s).
According to this question, two long-tailed corgis are crossed i.e. ss × ss. Each parent corgis will produce only 's' gametes. Using this gametes in a punnet square (see attached image), the following proportion of puppies will be produced:
All ss (long-tailed) offsprings/puppies.
Based on the question asked, 0% or none of the puppies produced will have a short tail.
Answer:
The correct answer is option c. "because the in vitro EGFR did not travel through the Golgi it was not properly tagged with the molecular modifications needed to localize to the membrane".
Explanation:
The epidermal growth factor receptor (EGFR) protein localization into the cellular membrane is a highly regulated process since the transmembrane part of the protein is very hydrophobic. The EGFR needs to go trough a series of post translational modifications in the Golgi apparatus, including glycosylation and subsequent folding processes. The EGFR synthesized outside the cells did not travel through the Golgi apparatus, therefore it does not go trough the post translational modifications and could not properly localize to the membrane.
Answer:
b
Explanation:
if the carrying capacity is exceeded then the ecosystem will run out of natural resources to maintain more population
Sedimentary rocks are the product of 1) weathering of preexisting rocks, 2) transport of the weathering products, 3) deposition of the material, followed by 4) compaction, and 5) cementation of the sediment to form a rock. The latter two steps are called lithification.
Answer:
D. If an earthworm is given a choice, it will move toward darkness rather than light.
Explanation:
A hypothesis must be a declarative statement that can be tested. That is the only one that follows the guidelines for a good hypothesis.
