an unknown cell was identified as being eukaryotic. what structure was identified to positively confirm this?

Mitosis is a type of cell division. organize the images below to show the steps of mitosis.

barxatty [35]

Answer:

The correct order is F, E, C, G, H, A, D, and B (look at the image in the attached files)

Explanation:

Interphase: Stages G1, S, and G2. At this point probably, the chromatin duplication has already occurred, but it is still lax or dispersed. It has not condensed yet. Two pairs of centrioles are outside the nucleus (FIGURE F)
Prophase: Centrioles move forward to the opposite poles of the cell. Chromatin is condensed and individual chromosomes are now visible. The nuclear membrane breaks into many pieces. Spindle apparatus -microtubules- forms. (FIGURE E)
Metaphase: The polar and the kinetochore fibers drive each individual chromosome to the equatorial plane. This stage ends when all the chromosomes are completely arranged in the medial area. (FIGURE C)
Anaphase: Sister chromatids separate and move to the opposite poles of the cells, driven by the microtubules. In each pole, there are a pair of centrioles (FIGURE G and H).
Telophase: The nuclear membrane rearranges. Each sister chromatid becomes now a new chromosome. There is a pair of centrioles outside each of the nuclei. (FIGURE A)
Cytokinesis occurs at the end of the cell division. The rest of the cell is divided into two new daughter cells. Each daughter cell is an identical copy of the other cell, with the exact same genetic material (FIGURE D).
Decondensation of the genetic material of each new cell (FIGURE B).

Nonrenewable resources are used much more prevalently today despite knowing that they pollute and will run out in the future. wh

KIM [24]

We are not using more renewable resources because we have been using fossil fuels since the 18th century and renewable resources are comparatively new. Also, we have limited knowledge about them, so it will take time to change our mindset toward renewable resources.

Based on exhaustibility, there are mainly two types of resources, renewable resources, and non-renewable resources.

Renewable resources are those resources that are replenished while non-renewable resources are those resources that are not replenished.

The non-renewable resources take millions of years to form and once exhausted they cannot be made more.

Examples of renewable resources are solar energy, wind energy, geothermal energy, etc. while examples of non-renewable resources are fossil fuels like coal and petroleum, metals, etc.

Despite the fact that the supply of non-renewable resources like coal and petroleum is limited and they also cause pollution, the use of them is rampant around the world.

The use of fossil fuels is widespread because we have been using them since the 18th century and the use of renewable resources is a very recent phenomenon.

Also, a major hurdle for using renewable resources is the upgrading of current technology to harness these resources.

The newer technologies are generally more expensive to employ, for example, the solar cells used for storing solar energy are made up of elements like silicon, silver, and gallium which are expensive.

Assuming a cell has just completed DNA synthesis, place these stages/steps in the cell cycle in the correct order of occurance b

shusha [124]

Answer:

The division of eukaryotic cell is done through various phase known as cell cycle.

Explanation:

The two basic phases of cell cycle is Interphase and Mitosis, that can be further divided into:

1) G2 Phase; G2 checkpoint ( Interphase stage)

2) Prometaphase (Mitotic Phase)

3) Anaphase (Mitotic Phase)

4) Telophase (Mitotic Phase)

5) cytokinesis (Mitotic Phase)

6) G1 Phase; G1 checkpoint ( Interphase stage)

After G1 phase there would be again S phase in which DNA replication occur.

Why are enzymes important for our bodies

valentinak56 [21]

Answer:

Because enzymes have many functions as chemical catalysts in numerous chemical reactions (for example in metabolism). By lowering the activation energy, they make it much easier to carry out reactions. They are also indispensable for signal transduction and cell regulation, often via kinases and phosphatases. They also generate movement, with myosin hydrolyzing ATP to generate muscle contraction, and also transport cargo around the cell as part of the cytoskeleton. Other ATPases in the cell membrane are ion pumps involved in active transport.
