Is it true that Humans are responsible for the direction of evolution during the process of artificial selection?
false
Connective tissue that processes a large quantity of collagen fibers often provide the frame work for organs such as the spleen and lymph nodes?
Reticular fibers hold in the spleen and other organs.
Do all animal cells contain the same type and quantity of organelles?
Organelles are contained within cells; each cell contains many of them. Some animals may by coincidence have the same number of organelles as another animal, but as a general rule they do not.
The structure and properties of the cell wall allow it to be selective and maintain homeostasis True or false?
False! It is the cell membrane that regulates the composition of the cell. In general, cell walls are highly permeable and allow most things to pass through in either direction.
Are A group of cells is called ORGAN true or false?
false
True or False A vector quantity has direction a scalar quantity does not?
true
Is momentum a vector or scalar quantity?
Momentum is a vector quantity. We know that momentum is the product of mass and velocity, and velocity has direction. That makes velocity a vector quantity. And the product of a scalar quantity and a vector quantity is a vector quantity.
Is distance a vector quanity?
It can be both true or false - you can treat distance as a scalar, or as a vector. If you say that (say) the distance from the cities of Cochabamba and Quillacollo is 13 kilometers - WITHOUT specifiying the direction - then it is a scalar. If you also say that Quillacollo is to the east of Cochabamba, then it is a vector.
Is momentum a scalar quality?
A vector quantity is one which transforms like the coordinates. In other words, if a coordinate system is transformed by an operator , any vector quantity in the old coordinate system can be transformed to its equivalent in the new system by the same operator. An example of a vector quantity is displacement (r). If displacement is a vector, the rate of change of displacement (dr/dt) or the velocity is also a vector. The mass of an object (M) is a scalar quantity. Multiplying a vector by a scalar yields a vector. So momentum, which is the mass multiplied by velocity, is also a vector. Momentum too transforms like the coordinates, much like any other vector. The definition of a vector as a quantity having "magnitude and direction" is simply wrong. For example, electric current has "magnitude and direction", but is a scalar and not a vector.
60 miles per hour would be a Scalar quantity because it represents a Magnitude but not Direction. is true or false?
TRUE. However, if you said '60 miles per hour in a northerly direction' , then that is a vector quantity. because it has direction.
Is vector quantity acceleration?
no, acceleration is not a vector quantity. its false
Acceleration is a vector quantity?
no, acceleration is not a vector quantity. its false
Acceleration is a vector quantity true or false?
True
Are speed and distance a pair of vector quantities?
Speed and distance are examples of scalar quantities, meaning they only have magnitude. Velocity and displacement are vector quantities, meaning they have both magnitude and direction.Examples of scalar quantities:speed (s) - 10 m/s or 36 km/hdistance (d) - 100 m or 0.1 kmExamples of vector quantities:velocity (v) - 10 m/s [E] or 36 km/h [E]displacement (Δd) - 100 m [E] or 0.1 km [E]The value in square brackets (for vector quantities) indicate direction and include, but not limited to:[S], [N], [E], [W], [45°], [45° E of S], [45° S of E], [forward], [backward] [up/↑], [down/↓], etc...
Why displacement is scaler?
Finding an answer to that question is exceedingly difficult, mainly because its hypothesis is false. Displacement is a vector, not a scalar.
The length of a vector arrow represents its?
The direction of the arrow represents the direction of the force; the length of the arrow is proportional to the magnitude of the force.
An object cannot be accelerating if it has a constant speedtrue or false?
An object with a constant (vector)velocity is not accelerating. An object with a constand (scalar)speed can actually be accelerating, a car with a constant speed that passes around a corner is changing direction and is subjected to a lateral acceleration.
