Fruit flies (Drosophila melanogaster) with a wild-type phenotype have gray bodies and red eyes. Certain mutations can cause chan

ges to these traits. Mutant flies may have a black body and/or cinnabar eyes. To study the genetics of these traits, a researcher crossed a truebreeding wild-typed male fly with a true-breeding female fly with a black body and cinnabar eyes. All of the F1 progeny displayed a wild type phenotype. Which of the following is correct about the traits observed?a. Gray body and cinnabar eyes are dominant.b. Eye color is sex-linked.c. Body color is sex-linked.d. Gray body and red eyes are dominant.

Answer:

d

Explanation:

The correct answer would be that <u>gray body and red eyes are dominant.</u>

The wild type trait  is represented by gray bodies and red eyes while the mutant trait  is represented by black body and/or cinnabar eyes. A cross between the wild type and the mutant only yield F1 offspring with wild type phenotype. This, thus, means that the wild type trait is dominant while the mutant trait is recessive.

<em>Since the wild type trait is depicted by gray body and red eyes, it means that the gray body and red eyes traits are dominant while the black body and cinnabar eyes are recessive.</em>

The correct option is d.

Travka [436]

The given question is incomplete as tiles are not given, however, the complete question is as follows:

Match the description of each organism to the appropriate category. Not all numbered options will be used. (Please match 1 number to 1 letter).

1. lives within an algae and produces sugars for the algae

2. lives in a marsh environment and aids in biodegradation

3. lives on rocks and produces it’s own food from inorganic materials

4. lives within the blood of another organism and causes disease

5. lives around the roots of a tree and provides nutrients to the tree

A. parasitic fungus

B. mutualistic fungus

C. saprophytic fungus

Answer:

The correct answer is -

A) Parasitic fungus-  4

B)  Mutualistic fungus - 5

C) Saprophytic fungus- 2

Explanation:

Fungi are organisms that are characterized by an organism that is microscopic, heterotrophic, and grows as long threads-like structures known as hyphae. These organisms can be divided into-

The parasitic fungi - a group of fungi that lives and depends on the host while harming theirs.

The mutualistic fungi - the group of fungi that lives mutually and obtains nutrients and provides benefit to the host.

The saprophytic fungi - fungi group that lives on the dead organic matter and decomposes it known as saprophytic fungi.

Considering the lungs are spongy tissue with air sacs, why would a difference in pressure cause the lungs to rupture? What is as
Dmitrij [34]

Answer:

When you ascend, water pressure decreases while the air in your lungs increases. Your lungs will overstretch and rupture. Asphyxiation is the deprivation of oxygen resulting in unconsciousness or death.

Explanation:

It usually happens to scuba drivers. Pressure changes will cause you injuries when you go down the water and then you go up. When you descend, water pressure increases while the air in your lungs decreases. When you ascend, water pressure decreases while the air in your lungs increases. Your lungs will overstretch and rupture. Asphyxiation is the deprivation of oxygen resulting in unconsciousness or death.

Explain three ways a proto-oncogene or tumor suppressor gene can lead to cancer.
Nimfa-mama [501]

Proto-oncogenes signal cells to grow and differentiate. However, they can become oncogenes due to mutations which result in the uncontrollable division of the cells, i.e. cancer. One way is a point mutation in a proto-oncogene. The consequence is changed protein product. Another way is gene amplification of DNA segment containing a proto-oncogene. As the result, the encoded protein is overexpressed. The third way is translocation. As the result of translocation, proto-oncogene can be controlled by the different promoter and expressed inappropriately.
