What are the types of cell?

The organisms which are made up of single cell has been known as the unicellular organisms and in the unicellular organism all the life processes takes place in a single cell. Amoeba has been known as an unicellular organism in which all the activities has to be related to the life carried out in a single cell.

Multicellular organisms are made up of the eukaryotic cell and the eukaryotic cell is consist of different cell organelles to carry out different functions in the cell. The multicellular organisms perform different life process in different cells because they have specific cell for specific function.

The unicellular organisms are made of one cell and carry out the processes of life as a single cell and the multicellular organisms are made up of two or more cells that have specific functions to contribute to the life processes.

Therefore, The substance will show net movement out of the cell more glucose and change to a black to purple color.

How are seatbelts related to inertia? Write you answer in complete sentences.
I need answer asap!!!

Answers

Answer:

Inertia- the tendency of an object to resist a change in velocity

Explanation:

Say a car was going at 65 MPH, but suddenly stopped. For all of the people in that car, their bodies would keep moving forward at 65 MPH until stopped by an equal force (say, the thing right in front of each person) The seatbelt is there to protect you from your own inertia.

Answer:

inertia is the constant state of movement so seatbelts stop that when you stop the car.

Answers

Answer:

Seat belts are in cars to the effects of inertia. ... When the car hits the wall, you would keep moving in a straight line and at a constant speed until the dashboard applies a force. Seat belts hold you and passengers down, protecting them from their own inertia.

Explanation:

their is the answer so okay

Answer:

Inertia is the tendency of an object to resist a change in velocity.

When a car stops suddenly, your body is still going at the same speed the car was before it stopped (say 65 MPH). Without the belt strapping you in from behind, you would fly forward at nearly that same speed (65).

But thanks to the seatbelt, it stops your body's inertia.

whats is the cell cycle and why is it so important to to our health? no links

Answers

The cell cycle is the replication of reproduction of cells, whether in eukaryotes or prokaryotes. It is important to organisms in many different ways, but overall it allows them to survive. For prokaryotes, the cell cycle, called binary fission, allows for them to live on by dividing into two new daughter cells. ( I hope this helped if you are doing this on computer you can copy & paste it. )

Are you talking about cell division and mitosis and that kind of stuff? If so , first is interphase which is growth and development second is prophase where you can see the chromosomes and spindle fibers everywhere, third is metaphase where the chromosomes line up and the spindle fibers are attached to the chromosomes, fourth is anaphase where the chromatid pairs separate, and last is telophase where the cell begins to form a new nucleus and split and goes back to interphase and the cycle continues. If this stopped then you would die. I hope this helped

It turns the Gulf Stream northeast and the Brazil Current northwest.

Answers

Answer:

The Coriolis effect acting on these currents causes northern hemisphere gyres to move in a clockwise direction and southern hemisphere gyres to move in a counterclockwise direction.

Explanation:

The Coriolis effect does the impact on the Gulf stream and the Brazil Current by turning the Gulf Stream towards northwest and Brazil Current northeast. Thus, the correct option is B.

What is Coriolis effect?

The Coriolis effect results in bending the direction of surface currents to the right in the Northern Hemisphere and left in the Southern Hemisphere. The Coriolis effect causes winds and currents to form the circular patterns. The direction in which they spin depends upon the hemisphere in which they are present.

Coriolis Effect is named after the French mathematician and physicist Gaspard-Gustave de Coriolis. It affects the weather patterns of an area, it affects the ocean currents, and it also affects air quality.

Therefore, the correct option is B.
