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.

In a particular breed of rabbits, fur color is gray or white. If a rabbit with gray fur and a rabbit with white fur reproduce and the offspring all have gray fur, what can you infer about the gene for fur color?

Answers

Answer:

D

Explanation:

The gene for dominant fur is dominant over white fur. The relationship between two genetic variants is referred to as dominant. Each gene has two alleles that an individual inherits from each parent.

What is dominant gene?

One allele of a gene, known as the dominant gene, will be expressed if the alleles are different. The impact of the other allele, known as the recessive one, is concealed.

Dominant describes the relationship between two genetic variants. If one is in charge, the other must be subordinate. Then it is referred to as recessive.

A dominant gene, or dominant form of a gene, is a specific variant of a gene that expresses itself more powerfully on its own than any other version of the gene that the individual is carrying—in this example, the recessive—for a variety of reasons.

Therefore, The gene for dominant fur is dominant over white fur. The relationship between two genetic variants is referred to as dominant. Each gene has two alleles that an individual inherits from each parent.

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

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

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.

Which statement is true:
1. The mass does not change because chemical changes observe the law of conservation of mass.
2. Mass is gained during the reaction because a chemical change is taking place.
3. Mass is lost during the reaction because the gas is less dense than the baking soda or vinegar.
4. Mass is lost during the reaction because the gas can change in volume but baking soda and vinegar cannot.

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.
