Letter to the editor,
Dear sir,
Never before in the history of this once proud and united country have elections divided this country in two. As the Democratic Party´s disagreement over the oficial party policy on slavery very clearly shows (with a Southern Democratic candidate and a 'normal' Democratic one), the deeply felt ideological split between the Northern and the Southern States has now, although Abraham Lincoln is chosen as the President, become a fact. This means that we, the United States of America, are no longer United.
The question is incomplete as it lacks the question and has only information regarding the question. however, the correct question is as follows :
How many different genes are contributing to the wingless phenotypes in these mutant fly strains?
Answer:
The correct answer is - Two genes.
Explanation:
In the given question there are two mutation groups based on the given seven results:
1st group :
Mutations 1, complement with 2,4, and 7 and also complement each other, thus, are on the same gene.
2nd group:
Mutations 3, 5, and 6 did not complement each other but complemented with mutations 1, 2, 4, and 7. Thus, these three mutations are present together on a different gene.
Explanation:
Matter can change form through physical and chemical changes, but through any of these changes matter is conserved. The same amount of matter exists before and after the change—none is created or destroyed. This concept is called the Law of Conservation of Mass.
Answer:
Light-sensitive cells in the retina at the back of our eye allow us to see.
1. The right answer is Spinal cord (central nervous system).
The spinal cord is a long and fragile tubular structure that begins at the lower end of the brainstem and ends at the bottom of the spine (spine). The spinal cord is made up of nerve fibers that carry incoming and outgoing messages that circulate between the brain and the rest of the body. It is also the center of reflexes, like the patellar reflex.
2. The right answer is Vegetative nervous system (called also autonomic nervous system).
The autonomic nervous system or visceral nervous system (also called the vegetative nervous system) is the part of the nervous system responsible for functions not subject to voluntary control. It controls particularly smooth muscles (digestion, vascularization ...), heart muscles, the majority of exocrine glands (digestion, sweating ...) and certain endocrine glands. The autonomic nervous system contains peripheral but also central neurons.
