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

s oblatus. You want to determine if this organism’s cells are similar in structure an organization to other eukaryotic cells. You collect the cells and examine them using a light microscope and a cell stain in an attempt to see the internal cellular structures. Lo and behold you are happy because you are able to see particular structures using this method. You find the following features: Organism’s cell are able to move Internal structures appears to be made of protein fibers Internal structures protein fibers measured 7.0 nanometers diameter Internal structures protein fiber appears to be two strands intertwined with each others Based on this information you come to the conclusion that you have been able to identify in these cells the structure of ____. You conclude the cells of Oviductus oblatus are indeed (name the main type of cell it appears to be) ______ cells. Discussion: Post your answers for the above scenario and include evidence that supports your choice

Answer:

  • Based on this information you come to the conclusion that you have been able to identify in these cells the structure of <em>microfilaments</em> or <em>actin filaments</em>.
  • <em>Oviductus oblatus</em> 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 <u>polymer of proteinic subunits</u> united by weak, not covalent connections.

The microfilaments are the thinnest of the three structures. They have a <u>diameter of 7 nanometers</u> and are <u>composed of many proteinic monomers</u> 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 <u>they are often used as molecular markers</u> for different studies.

Identify correct statement from the following
SpyIntel [72]

Answer:

The answer is statement 1, 2, and 3

Explanation:

A hypothesis is a starting point for further investigation, therefore a hypothesis will always be a possibility at least until it is tested.

Variable is a factor that is liable to vary or change.

A hypothesis without being tested is merely a statement or an explanation made on the basis of limited evidence. Therefore it is unsure whether the said statement is true or not.

A hypothesis can still be proven by further investigation with different variables

where are already given with
c = 0.1 and C = 0.9
SO
p2 = 0.9^2
p2 = 0.81
q2 = 0.01
0.81 + 2pq - 0.01 = 1

kykrilka [37]

Answer:

There are no options in this question but generally a sample of DNA can be increased;

By using Polymerase Chain Reaction (PCR) technique.

Explanation:

This question describes the application of making molecular biology to solving a crime problem; a branch called forensics. In this case where an insufficient small amount of DNA sample was recovered from the blood in a crime scene, the polymerase chain reaction technique, commonly known as PCR can be used to increase the DNA sample.

In the 1980's, a molecular technique used to amplify part of a template DNA strand to produce several copies of it, was invented by Kary Mullis and his colleagues. This amplification refers to the numerical increase in the number of DNA sequence.

Which correctly lists three properties that are used to identify minerals? luster, weight, streak magnetism, size, weight size,
Dovator [93]

Answer:

luster, streak, hardness, cleavage, fracture, and crystal form are the most useful physical properties for identifying most minerals. Other properties-such as reaction with acid, magnetism, specific gravity, tenacity, taste, odor, feel, and presence of striations-are helpful in identifying certain minerals.
