Both mitochondria and ribosome are so tiny structure, it can not be seen under light microscope. It needs more magnification to study the detail structure, hence electron microscope is best to use.

<h3>What is ribosome ?</h3>

Ribosomes are small membrane less organelles and are the sites of protein synthesis.

It is present in are found in both eukaryotic and prokaryotic cells.

Ribosomes can either be present alone or in groups in cytoplasm while some ribosomes are attached to the endoplasmic reticulum  called as rough endoplasmic reticulum.

These are composed of ribosomal protein and RNA, have two subunit larger and smaller subunit.

ZWhat Organelle that conducts respiration for the cell
baherus [9]

Answer:

The organelle that conduct respiration for the cell is MITOCHONDRIA.

Explanation:

The cells of living organisms are made up of different organelles, each of the organelles have specific functions, which they perform. The mitochondria is the cell organelle that is responsible for carrying out respiration in the cells. Respiration involves the breaking down of glucose molecules in order to produce energy in form of ATP. Mitochondria is also called the power house of the cell because of its function of energy production.

How does air pressure affect weather
UNO [17]

Answer:

<em>Hewo, Kiluawa (sorry if i spelled it wrong) </em>

Explanation:

High Pressure

Basically, high pressure occurs in an area if the atmosphere over that particular area becomes heavier. As a result, the heavy air above will come down to the Earth’s surface. And the air present in that area will move away to create space for the heavy air.

Commonly, the warmer months experience high pressure. You’re more likely to enjoy a comparatively dry and stable weather pattern in those months. Besides, you’ll find the skies in high pressure areas very clear. You’ll also feel a gentle breeze there that will cool down the surrounding areas.

Low Pressure

On the other hand, the air above a low pressure area is comparatively much lighter than the air below. As the heavy air on the Earth’s surface cannot go further below, it pushes away the lighter air above. As a result, a vacuum is created on the surface level and the air in the surrounding areas rushes towards it to fill up the void space.

Meanwhile, the rising air starts to cool down and form clouds in the sky. These clouds then come down to the Earth in the form of rain. Sometimes, snow is also formed depending on the temperature of the surrounding areas.

In general, colder months of the year experiences more low pressure situations. By now, you probably can guess why. The cold air on the surface level is heavier than the air above. And these low pressure areas are the reasons behind unstable weather conditions like snow, ice, rain, storm, etc.

Hope This Helps!

Which of the following terms are NOT used interchangeably? muscle tension - muscle force in vivo - in the body/ the living muscl
Karo-lina-s [1.5K]

Answer:

The correct answer is "motor unit - motor neuron".

Explanation:

Motor unit and motor neuron are related terms, however they could not be used interchangeably because a motor unit is not comprised only of a motor neuron. A motor unit is made of a motor neuron, skeletal muscle fibers and neuron's axonal terminals. Therefore motor unit is a more broadly term, and is referred to the units that coordinate the contractions of single muscles.
