Select the correct statement about bacteria.
kompoz [17]

Answer: C. Certain bacteria live within rocks kilometers below the Earth’s surface.

Explanation:

Bacteria are microscopic, usually single-celled living organisms that can be found in many environments. The live in practically anywhere on the planet because they are able to adapt to environmental changes. Bacteria regulate changes or modifications to their cell envelope in a coordinated way, allowing them to survive in different environments.

The main difference between bacteria and other cells is that bacteria are cells that do not contain a nucleus or other membrane-bound organelles.

These organisms can live in soil, the ocean and also inside the human gut.  They can be dangerous, for example, when they cause infections they are able to injure different cells and tissues and compromise the immune system. On the other hand, most of the time they are beneficial, as in the process of fermentation such as in wine or yougurt, or helping with the digestion.

Sense a dog has 78 chromosomes in their body cells and humans have 46, are dogs more complex than humans do to have a more chrom
Ksivusya [100]

Answer:

No

Explanation:

A carp (a kind of fish) has 104 and a rattlesnake fern has 184. Most likely neither of these is as complicated as we are (especially the fern).

These kinds of differences are out there because the number of chromosomes doesn’t have anything to do with how complicated or “advanced” a living thing is. What matters is what is on them.

Your fewer chromosomes have the set of instructions for making you and a potato’s chromosomes have the set of instructions for making a potato plant. It doesn’t matter how many pieces those instructions are cut up into.

Think about it like comparing the instructions for building a car to the instructions for building a bicycle.

Let’s say the car’s instructions are in one big book but the bicycle’s instructions are spread over five books. Making a bicycle isn’t more complicated than a car just because it is in five books instead of one. Same thing with your chromosomes and a potato’s chromosomes.

It also doesn’t always have to do with how many “pages” or even sets of instructions are in something’s chromosomes.

A communications satellite transmits a radio wave at a frequency of 9.4 x 10^9 Hz. What is the signal’s wavelength? Assume the w
sergejj [24]
To calculate this we will use the light equation:
c=λ*f

We have Frequency f=9.4* 10^{9}Hz.
We know that speed of light in vacuum is c =3.8* 10^{8} m/s.
Since a unit of speed of light is m/s, we can change the unit of frequency Hz to 1/s, since Hz means cycles per second (f=1/T).

So:
f=9.4* 10^{9}1/s
<span>c =3.8* 10^{8} m/s
</span>
<span>c=λ*f
</span>⇒ λ= \frac{c}{f}
⇒ λ= \frac{3.8* 10^{8}}{9.4* 10^{9}}
⇒ <span>λ</span>=0.04 m
