Niche refers to the role of the microorganism or a living thing in an ecosystem. When two organisms occupying the same niche, the possible long-term consequence isA. local extinction. This is because the relationship is competition which can outlast the other. Eventually, when the environment is changed, the organisms adapt too which erases the original attributes.

A pea plant is heterozygous for both seed shape and seed color. S is the allele for the dominant, spherical shape characteristic
kati45 [8]

So, you would make a punnet square. You would put the capital S and lowercase s on the top of it and then the capital Y and lowercase y on the side. Then you should have SY, sY, Sy, and sy as your outcomes.

A geneticist is studying two traits in the fruit fly - eye color and wing shape. They perform a dihybrid cross. If the genes for
Len [333]

Answer:

3/16

Explanation:

<u>According to Mendel's law of independent assortment of genes, when a dihybrid cross involves two genes that assort independently and one of the parents is dominant for the two genes and the other is recessive, the phenotypic ratio of the offspring at F2 would be 9:3:3:1</u>. The proportion of the offspring with the dominant parental traits would be 9/16, those with the recessive parental traits would be 1/16, while those with mixed traits would be 3/16 each.

Assuming the eye color is represented by E and the wing shape is represented by W. At F2

     EeWw    x    EeWw

E_W_ - 9/16 (dominant for both eye color and wing shape)

E_ww - 3/16 (dominant for eye color and recessive for wing shape)

eeW_ - 3/16 (recessive for eye color and dominant for wing shape)

eeww - 1/16 (recessive for both eye color and wing shape)

<em>Hence, the proportion of the offspring with dominant phenotype for eye color and recessive phenotype for wing shape would be </em><em>3/16.</em>

In numerous studies, treatment of prion preparations with ionizing and UV radiation does not reduce transmission of disease; how
mel-nik [20]

Answer:

A. Prions do not contain genetic information, which is affected by ionizing radiation.

B. Denaturants may affect the tertiary structure of prions.

C. Prions are proteins.

Explanation:

Prions are the proteinaceous infectious particles that cause many degenerative diseases of neurons in both animals and humans. They consist of only protein and no DNA or RNA. Due to the absence of DNA or RNA as genetic material, these infectious particles are resistant to ionizing radiation. Ionizing radiations affect nucleic acids of pathogens to destroy them.

Denaturation of proteins affects their secondary and tertiary structures and leave them non-functional. Denaturation may be caused by changes in temperature, pH, disturbance of hydrogen bonds, etc. Therefore, to destroy prions, they need to be denatured.

Having a standard taxonomic system benefits the scientific community by allowing scientists from all over the world to do ______
Nikitich [7]

Answer:

<h2>Have a common understanding in the classification of organisms</h2>

Explanation:

  • Taxonomy plays an important role in the classification of organisms to study the organisms on the basis of their properties.
  • Taxonomy is a branch of biological science that explains the identification, characterization, naming and classification of the organisms thus it is helpful to understand the different types of organisms that are present in the biosphere.
  • Taxonomy makes the scientist come on one point about the unknown organisms according to morphology, anatomy, physiology and some other properties of the organisms.
  • Thus a common understanding is generated among scientists of the world.
