It's chemoautotrophs because cyanobacteria can be mixotrophic if needed and they are classified as algae.

Chemoautotrophs make their own food by extracting compounds from the ocean.

Chemoautotrophs are organisms that obtain their own food (energy) from inorganic chemical compounds such as sulfur, ferrous iron, hydrogen sulfide and ammonium in their environment. These occur by chemosynthesis in which the organisms use chemical energy to produce carbohydrates. Chemoautotrophs are usually found in hostile environments such as at the bottom of the ocean or in acidic hot springs. Examples of chemoautotrophs include; thermoacidophiles, methanogens, nitrifiers and halophiles.

According to the ______________ theory, a population may go long periods of genetic stability, interspersed with short periods o

ikadub [295]

<span>This theory is called punctuated equilibrium. In this theory it is explained that there are very long periods of no change at all to a species, yet there are also bursts of evolutionary change interspersed within the time period. The period of remaining the same throughout time (most of the time) is called stasis, and is present within this theory of punctuated equilibrium.</span>

In ________ conditioning, the unconditioned stimulus unconditionally elicits a reaction. For example, a bit of black pepper blow

kipiarov [429]

Answer:

The answer is: Classical Conditioning.

Explanation:

According to the theory of Classical Conditioning, an Unconditional Stimulus can be defined as such a stimulus that is capable of triggering a response spontaneously and naturally without the requirement of a previous learning or knowledge about the stimulus.
A Neutral stimulus can be defined as such a stimulus which is responsible for drawing or focusing the attention of a person to a particular event.
A Conditional Stimulus can be defined as such a stimulus which is generated due to the repeated integration of an Unconditional stimulus to a Neutral stimulus. The repeated integration eventually results in the generation of a conditioned response.
In the given example, a bit of black pepper blown into the eyes for the first time is an example of unconditional stimulus. This stimulus initiates a spontaneous or unconditional response, that is, blinking of eyes.
But, when this unconditional stimulus gets integrated to the neutral stimulus (irritation in the eyes draws the attention of the person) repeatedly, it can result in the generation of a Conditioned Response (blinking of eyes whenever any foreign object gets into it).

More blood vessels are stimulated to ______ more than ______ because blood vessels contain more ______ receptors than ______ rec

serg [7]

More blood vessels are stimulated to vasoconstrict more than vasodilate because blood vessels contain more alpha receptors than beta receptors.

<h3>What is Vasoconstriction?</h3>

This is the process which involves the narrowing of the blood vessels through their muscle wall.

They contain more alpha receptors such as Alpha-adrenoceptor agonists than beta receptors which mimicks the effects of sympathetic adrenergic nerve activation to the blood vessels.

Why is Biology so hard?

Masteriza [31]

Answer:

Imagine studying a cell. That cell has billions of things you can learn about. Now imagine 37.2 trillion cells each a little bit different but still similar. Now imagine that multiplied by all the different people there are on earth. Now then include all the other types of living animals.

That's biology
