Answer:

Microorganisms and all other living organisms are classified as prokaryotes or eukaryotes. Prokaryotes and eukaryotes are distinguished on the basis of their cellular characteristics. For example, prokaryotic cells lack a nucleus and other membrane‐bound structures known as organelles, while eukaryotic cells have both a nucleus and organelles. Prokaryotic and eukaryotic cells are similar in several ways. Both types of cells are enclosed by cell membranes (plasma membranes), and both use DNA for their genetic information.

<u>Prokaryotes</u> include several kinds of microorganisms, such as bacteria and cyanobacteria. <u>Eukaryotes</u> include such microorganisms as fungi, protozoa, and simple algae. <u>Viruses</u> are considered neither prokaryotes nor eukaryotes because they lack the characteristics of living things, except the ability to replicate (which they accomplish only in living cells). Viruses - Corona virus, HIV.

Answer:

Like a prokaryotic cell, a eukaryotic cell has a plasma membrane, cytoplasm, and ribosomes, but a eukaryotic cell is typically larger than a prokaryotic cell, has a true nucleus (meaning its DNA is surrounded by a membrane), and has other membrane-bound organelles that allow for compartmentalization of functions.

Do you see a connection between wavelength and frequency? Explain.

katrin2010 [14]

Answer:

Wavelength and frequency of light are closely related. The higher the frequency, the shorter the wavelength. Because all light waves move through a vacuum at the same speed, the number of wave crests passing by a given point in one second depends on the wavelength.

Amplitude is the height of a wave which is the brightness of a light or loudness of a sound. So Frequency and Amplitude though are part of a wave are not dependent on each other. Their is no relation between frequency and amplitude.

Newton's law of universal gravitation states that... 1. small masses don't exert gravity on larger masses 2. earth's gravity can

Allushta [10]

Description
Newton's law of universal gravitation is usually stated that every particle attracts every other particle in the universe with a force which is directly proportional to the product of their masses and inversely proportional to the square of the distance between their centers.

Summary of hearing: Vibrations cause the cochlea’s membrane to shake. This causes ripples in the ____________, bending the _____

mash [69]

Answer:

1) Basilar membrane

2) Stereocilia or hair cells

3) Nerve cells

4) Auditory

5) Temporal lobe

Explanation:

Basilar membrane: located inside of the cochlea which is located in the inner ear. This membrane separates two tubes that is filled with liquid which is also important for hearing.

Hair cells: Connected to the basilar membrane and they acts as sensory receptors which can catch movements (ripples) in the basilar membrane and pass this message to the neurons.

Nerve cells: One of the main cell types in the brain, which are responsible for signal transfer.

Auditory cortex: This part of the brain is located in temporal lobe and handles the auditory information.

What type of plant would be least affected by the loss of the guard cell function that closes stomata?.

maks197457 [2]

A rainforest plant would be least affected by the loss of guard cell function that closes the stomata.

<h3>What is Guard Cells?</h3>

Guard cells are types of specialized plant cells present in the epidermis of leaves, stems, and other organs that are used to control gas exchange.

They are produced in pairs with a gap between them that forms the stomatal pore. They are kidney-shaped cells that surround stomata and control the opening and closing of stomata.

When there is an excess of water in the plant, the guard cells swell and form a hole for the exchange of gases.

Thus, a rainforest plant would be least affected by the loss of guard cell function that closes the stomata.
