Using data, provide evidence that evolution is an ongoing process.

The major evidence that the evolution is still ongoing is mutations that occur. Those changes at gene level happen by chance during the process of copying DNA and change through the populations over time. Individuals who reproduced can pass that mutation to their offspring. When carriers with a specific mutation are better able to survive and reproduce, natural selection will favor them. That is the way of new variant to be passed down and spread through the population.

What type of cell has abundant mitochondria?

GuDViN [60]

In general cells that need more energy, since mithocondria are responsible for making and processing ATP.

Common examples of cells with many mithocondria are muscle cells that are in current activity all the time, specially heart muscles and muslces in the respiratory system such as the diafragma since the heart beats all the time, non-stop, that is, unless you die of course and so do the muslces needed to breath.

QveST [7]

Answer:

Food pellet

Explanation:

A learning process which results due to an associated between two stimuli, one a natural stimulus and the other an environmental stimulus is known as classical conditioning.
For classical conditioning, there is a neutral stimulus as well as the unconditioned stimulus.
The unconditioned stimulus is the one which triggers a response in the organism automatically that is naturally without any prior learning.
In the given example, the food pellet is the unconditioned stimulus.

List four ways in which viruses can be similar or differ from each other.

Karolina [17]

Answer:

Are you talking about bacteria type viruses? because that's what I would assume.

Explanation:

Well, all viruses have a core of genetic material like RNA or DNA.

Viruses can have different families, geonomic makeup, host range and transmission mechanism.

I hope this helped in a way.

emmainna [20.7K]

Answer:

Reduction of sulfur compounds and the release of hydrogen sulfide is happening here.

Explanation:

Sulfur is an important element in the sulfur cycle. Sulfur compounds can be found on earth in various forms. They can be found in mineral rocks and organic matter. It is the work of bacteria to reduce sulfur compounds and convert them to sulfides.

There are different types of bacteria that reduce various sulfur containing compounds. They are sulfate-reducing bacteria, sulfur-reducing bacteria, sulfite reducing bacteria etc. In a swamp there is low oxygen availability and organic matter decays in this condition.

The sulfate reducing bacteria oxidizes the organic matter and releases Hydrogen sulfide.
