Answer:

Robert Hooke

I hope this helps you :)

Roobert Hooke  first scientist to observe cells using a microscope.

Thus, Microscope: a device that magnifies small objects, giving the user a close-up view of minuscule structures at a scale suitable for observation and analysis.

Even though optical microscopes are the focus of this article, an image can also be magnified by a variety of different wave types, such as acoustic, X-ray, or electron beams, and is then captured using direct or digital imaging, or a combination of these techniques.

The microscope can produce a static image, similar to a traditional scanning electron microscope, or a dynamic image, like traditional optical devices.

Thus, Roobert Hooke  first scientist to observe cells using a microscope.

Explanation:

All viruses are obligate parasites; that is, they lack metabolic machinery of their own to generate energy or to synthesize proteins, so they depend on host cells to carry out these vital functions.

A researcher wanted to know if attractive people are more likely to receive help when in need, compared to unattractive people. if the investigator randomly assigned participants to groups that involved an attractive confederate versus an unattractive confederate, such a study would involve 'imdependent' variable.

Physically attractive defendants will receive shorter prison sentences than physically unattractive defendants. In an experiment, the hypothesis is an assumption that the researcher makes and that will be tested during the execution of the experiment. This assumption is created from the researcher's observation about a certain situation or element.

In the case of the experiment presented in the question above, we can see that the researcher observed that physically attractive or unattractive defendants have different sentences after the trial. From this, this researcher created a hypothesis, he assumed, that physically attractive defendants will receive lower sentences than defendants who are not physically attractive.

Therefore, A researcher wanted to know if attractive people are more likely to receive help when in need, compared to unattractive people. if the investigator randomly assigned participants to groups that involved an attractive confederate versus an unattractive confederate, such a study would involve 'imdependent' variable.

Answer:

Image 3

Explanation:

Prokaryotic cells are single-celled organisms that lack membrane-bound organelles, including a defined nucleus.

The only cell without membrane-bound organelles is image 3

Image 1 is a single-celled eukaryotic organism, probably a paramecium.

Image 2 is a plant cell (has a cell wall)

Image 3 is a bacterium

Image 4 is an animal cell

We have mentioned how atoms and molecules can absorb photons, thereby ... case of what happens when a hydrogen atom absorbs light in the visible or UV region of ...

 the objective and ocular lenses are responsible for magnifying the image.

so for 10x objective and 10x ocular

total magnification= 10x10= 100x(this means that the image being viewed will appear to be 100 times its actual size)

      a)scanning(small lens),red ring=4x or 5x

      b)low power (medium lens), yellow ring = 10x

      c) high power (large lens),blue ring = 40x

      d)oil immersion (largest lens),white ring = 100-250x

 4.immersion oil helps to focus on lighting

 5. total magnification=15x40 =600x

 6. diaphragm controls the amount of light reaching the specimen.

They control both the focus and quantity of light applied to the specimen.

Answer:

It is important to point out that muscle cells have a very high concentration of mitochondria that produce ATP. Your muscle cells need a lot of energy to keep your body moving. When your cells don't get enough oxygen, they do not make a lot of ATP.

Explanation:

Muscle cells have a high concentration of mitochondria.

Regulation of metabolic enzymes in skeletal muscle occurs in response to changes in ATP demand, substrate availability, and in response to hormonal and neural stimulation.

The muscle fiber is an elongated cell whose length can reach several centimeters.

The sarcoplasm of a muscle fiber contains many mitochondria.

They are those that produce energy (ATP) directly usable by the muscle fiber to contract its myofibrils, which are the contractile elements of skeletal muscle cells.

Therefore, we can conclude that adenosine triphosphate (ATP) is the basic source of energy for muscle contraction is ATP and muscle cells have a high concentration of mitochondria.
