Sickle Cell anaemia is an
1) autosomal recessive
2) autosomal dominant
3)Sex linked
4) both 1 and 2​

Answer:

1

Explanation:

it's an autosomal recessive trait.

Answer:

3) sex-linked

Explanation:

It is carried by the sex chromosomes, mainly the X chromosome. An individual has the disease when he gets an X chromosome bearing the disease from a carrier or infected mother or both two X chromosomes each bearing the disease, one from each parent. Thus in the case of a girl... Hence, it is sex-linked

Water was rediscovered on the Moon in 2020. How is the recent discovery different from the LCROSS discovery and why is it potentially exciting for humans?

The law of universal gravitation states that both mass and distance of objects affect the gravitational force between them. Gravitational force increases as the mass of the objects increase. Gravitational force decreases as distance between the objects increases. Why are these statements considered scientific law, and not scientific theory?

A conditional mutation expresses its mutant phenotype only under certain conditions (the restrictive conditions) and expresses the normal phenotype under other conditions (the permissive conditions). One type of conditional mutation is a temperature-sensitive mutation, which expresses the mutant phenotype only at certain temperatures. Strains of E. coli have been isolated that contain temperature-sensitive mutations in the genes encoding different components of the replication machinery. In each of these strains, the protein produced by the mutated gene is nonfunctional under the restrictive conditions. These strains are grown under permissive conditions and then abruptly switched to the restrictive condition. After one round of replication under the restrictive condition, the DNA from each strain is isolated and analyzed. What characteristics would you expect to see in the DNA isolated from each strain with a temperature-sensitive mutation in its gene that encodes the following?a. DNA ligase
b. DNA polymerase I
c. DNA polymerase III
d. Primase
e. Initiator protein

Harry had been learning about joints in one of his classes at school. On the way to the emergency room he tried to recall what types of tissues made up the different joints. He knew ligaments, tendons, and other connective tissues associated with joints often did not heal quickly. He wasn't sure whether it would better to have broken a bone or to have sprained something. Correctly match each tissue type to the sentence. Some of the words may be used more than once.

B.
a fairly high rate of gene flow between human populations
C.
a fairly short time, perhaps 200,000 years existing as a new species in Africa
