Answer:

C.Use a microscope to observe the shapes of the bacteria.

Explanation:

Bacteria is a type of pathogenic micro-organisms. They are mostly known to cause diseases and can be viewed using an electron microscope.

Bacteria have different shapes and colors. The shapes include bacilli(rod shaped), cocci(spherical)or spirilla( twisted).

The most useful strategy will be to use a microscope to observe the shapes of the bacteria.

A close friend has joined a clinical trial. When you ask her about the types of treatment she might be given, she tells you that

Radda [10]

Answer:

A. double-blind

Explanation:

Based on the scenario being described within the question it can be said that the type of trial that she has joined is known as a double-blind study. This is a type of study in which individuals are chosen randomly for each clinical intervention and the results are not given to the researchers until after the trial. This also includes any and all information that may influence the researchers behavior or thoughts on the study.

Scenario: You are a research scientist and are working with eukaryotic cells obtained from a newly discovered organism, Oviductu

Minchanka [31]

Answer:

Based on this information you come to the conclusion that you have been able to identify in these cells the structure of microfilaments or actin filaments.
Oviductus oblatus are indeed eukaryotic cells

Explanation:

In eukaryotic cells, the cytoskeleton is composed of three well defined filamentous structures: microtubules, microfilaments, and intermediate filaments. Each of these filamentous structures is a polymer of proteinic subunits united by weak, not covalent connections.

The microfilaments are the thinnest of the three structures. They have a diameter of 7 nanometers and are composed of many proteinic monomers united. This monomeric protein is called actin. Many monomers get combined to form a structure that assembles a double helix.

Due to the fact that these microfilaments are made of actin monomers, they are also known as actin filaments.

Actin filaments have directionality which means that their extremes have different structures.

In eukaryotic cells, genes that codify for actin microfilaments are highly conserved in all organisms, which is why they are often used as molecular markers for different studies.
