A scientists is trying to decide whether an organism is unicellular or multicellular which information would help the scientist most make her decision?A.size of cells of the organism

B.what the organism eats

C.how many types of cells are in the organism


D.how fast the organism grow

Answers

the answer is c J think

Final answer:

The most relevant information to determine whether an organism is unicellular or multicellular is the number of cell types in the organism, as multicellular organisms tend to have many different cell types, while unicellular organisms have just one.

Explanation:

If a scientist is attempting to determine if an organism is unicellular or multicellular, the most helpful information would be to understand how many types of cells are in the organism (option C). This is because multicellular organisms generally have many different types of cells carrying out specialised functions (e.g., nerve cells, blood cells, muscle cells), whereas unicellular organisms only have one cell type that fulfils all life functions.

For example, a human (a multicellular organism) has several different types of cells such as skin cells, kidney cells, and heart cells. On the other hand, an amoeba (a unicellular organism) has a single cell handling all functions necessary for survival.

86 Km/h convertir a (m/min)

Answers

Answer: 1433.3 m/min

Explanation:

For 86 Km/h converted to a (m/min), convert kilometers to meters, and hour to minutes

So, 86 Km/h means 86 kilometers per 1 hour

- If 1 kilometer = 1000 metres

86 kilometers = 86 x 1000 = 86,000m

- If 1 hour = 60 minute

1 hour = 60 minutes

In m/min: (86,000m / 60 minute)

= 1433.3 m/min

Thus, 86 Km/h convert to 1433.3 m/min

Answers

It is an example of a constraint as if you are unable to meet the amount of purchasing power required to obtain a product, you will be unable to acquire said product, thus constraining you.

How could you increase the kinetic energy of a truck without increasing its velocity?

Answers

Kinetic energy consists of 2 elements, mass and speed. If its velocity, that is speed, remains the same, you have to increase the mass to increase its kinetic energy without affecting velocity.
Kinetic energy of something depends on its mass and speed. 
So if you want to keep the same speed but increase its kinetic
energy, then the simple answer is that you have to increase the mass.

But it's not as simple as that.

If there's a truck cruising along the highway, and you want to increase
its kinetic energy without changing the speed, then it's true ... you'll
have to increase the mass.  You might have a helicopter swoop in low
over the truck and drop some bales of hay onto it.  That will certainly
increase the mass. But that DOESN't magically increase the kinetic
energy.  More energy has to COME from somewhere.

When the bales hit the bed of the truck and the mass suddenly increases,
if the driver doesn't want his speed to drop, he has to mash the gas pedal
a little farther, run the engine a little faster, and let the engine deliver more
energy.  THAT's where the extra kinetic energy comes from ... extracting
more chemical energy out of more gasoline.
