What evolutionary advantage does a eukaryotic cell have compared with a prokaryotic cell?
Luden [163]

Answer:

Prokayotes may be defined as the organisms that lacks the nucleus and the membrane bound cell organelle. Eukaryotes have the well defined nucleus and contains the membrane bound cell organelle.

The evolutionary advantage that has been noticed in the eukaryotic cells is the compartmentalization of the cell. The cell compartmentalization separates the cell organelle into the specialized functions. This division of labor increases the efficiency of the cell and regulates the evolution of the complex multi cellular organism.

Superantigens produce intense immune responses by stimulating lymphocytes to produce Superantigens produce intense immune respon
Viktor [21]

Answer:

Superantigens produce intense immune responses by stimulating lymphocytes to produce cytokines.

Explanation:

Superantigens are a group of bifunctional proteins that interact with at least two receptors expressed on different cells.  The superantigen´s receptors in lymphocyte T is located in the same place where the lymphocyte interacts with a conventional antigen, RCT. The capability of these superantigens to join their receptors in many T cells, shoots a series of processes that conduce to cellular activation, differentiation, proliferation, and great production and release of cytokine.    

Superantigens constitute the most potent natural immunostimulators known.

How might biodiversity in Area 1 change if the new bird species ate small mammals, lizards, and toads?
zmey [24]

Knowing that Biodiversity is the variety and variability of life on Earth. Biodiversity is typically a measure of variation at the genetic, species, and ecosystem level. Terrestrial biodiversity is usually greater near the equator, which is the result of the warm climate and high primary productivity. The ecosystem will change if a new species is introduced to an unfamiliar ecosystem. If a new species of birds were to eat another animal that was supposed to be eaten by another. The food chain of the ecosystem would be changed drastically. Aka, it might make the lizards go extinct, and can possibly become abundant. Aka, overpopulating and creating havoc within the ecosystem. Thus, causing imbalance.

vince stains dna with a dna-binding dye. what suborganellar structures will become visible after staining?
Basile [38]

The suborganellar structure that will become visible after staining is nucleoid.

In the field of biology, nucleoid can be described as a region inside the prokaryotic cell in which the DNA is present.

The prokaryotes do not have a membrane-bound nucleus like the eukaryotes. Hence, the region where the genetic material of the prokaryotes is present is an irregular shaper structure referred to as the nucleoid.

When DNA is stained with a DNA-binding dye, the suborganellar structure that will become visible will be the nucleoid as it is the region where the DNA is present.
