What causes the dangerous red tides in the ocean?

Leto [7]

<span>Red tides are formed by dinofllagelata, eucaryotic flagellate organisms. Dinoflagellates are marine plankton which means they drift on the surface of the sea. Those are small, nonmobile organisms who sometimes bloom in concentrations of more than a million cells per ml. The bloom is often red colour so the phenomenon is called red tides. </span>Under such circumstances, they can produce toxins, dinotoxins<span> which are capable of killing fish, so that's why this occurrence is dangerous.</span>

Was the membrane at a stable equilibrium before you pushed it? How could you tell?

liq [111]

Answer:

Well, first let's define the difference between stable and unstable equilibrium.

Stable: After a little perturbation, the equilibrium state is retaken.

Unstable: After a little perturbation, the state changes to one more stable.

An example of this is:

Imagine a pencil, when the pencil lays down in the table, it is in stable equilibrium because you can touch it and it will return to the same initial state.

Now suppose that the pencil is standing up (we can think this as a more energetic state). The pencil is in equilibrium, it does not move and there is no force acting on it.

Now you can touch it (a small perturbation) and the pencil will likely fall down, to the stable state of equilibrium.

That is the difference between stable and unstable (There is also an image below, where you can see it in a more physical way, where the vertical axis represents energy and the horizontal represents a given variable or set of variables).

Then, how to know if the membrane was at a stable equilibrium before you pushed it?

Did it return to the initial state? then yes, it was a stable equilibrium

Did It change to a less energetic state? Then no, it was in an unstable equilibrium.

A child watches an older sibling playing with a ball but makes no effort to participate in the play. Which social character is t

Blababa [14]

Answer:

Onlooker play

Explanation:

In onlooker play a child actively observes other children playing and does not attempt to enter into the activity; the child is interested only in observation and not in participation. In parallel play children play independently among other children. In pretend play children act out any event of daily life and practice the roles and identities as established in their surroundings. In associative play children play together and are engaged in a similar or identical activity.

According to the author, what is the main reason for the decrease in trillium in the forest?

castortr0y [4]

Answer:

The main reason for the decrease in trillium is the large number of deer in the forest that are eating the trillium. The author cites a research study performed by scientists as evidence to support her claim. In this study, researchers planted two fields, each containing garlic mustard, and trillium.

This organelle is referred to as the power house of the cell.

Reika [66]

The mitochondria is referred to as the power house of the cell, as this is there most of the cell's usable form of energy comes from, due to the process of cellular respiration.
