The correct matching of the organisms to their descriptions is given below:
Starfish - lacks colored bloodBird - is a vertebrateOctopus - has a soft, unsegmented bodyScorpion - lacks antennaeWhat is an Organism?Any organic, living system that performs as an independent unit is referred to as an organism. Cells comprise all living things. Multicellular mammals, plants, and fungi are examples of multicellular creatures. Unicellular microorganisms include bacteria and archaea.
All kinds of creatures can have the capacity for procreation, growth and development, maintenance, and to some extent, stimulus-response. Multicellular organisms such as beetles, tetrapods, mushrooms, and vascular plants grow a variety of tissues and organs.

What state of matter has the highest energy? Lowest?
Answer:
The highest state of matter in energy is gas. The lowest is solid.
Explanation:
The reason why is because gas is the highest conductor of electricity (which is why we have lightning). However, solids don't conduct electricity very well.
Urgent and easy

Which answer explains why plate B is moving underneath plate A
A. Plate B is more dense than plate A because it is composed of oceanic crust
B. Plate A is more dense than plate B because it is composed of oceanic crust
C. plate B is more dense than plate A because it is composed of continental crust
D. Plate A is more dense than plate B because it is composed of continental crust
Answer:
A.
Explanation:
Earth is composed of different layers and one layer moves over another due to differences in the densities.
According to the physics of density, a substance having less density floats over a higher density substance. The oceanic crust has more density than the continental crust that is why continental crust float over oceanic crust.
So in the given example, plate B is moving below the plate A, it means plate B is more dense than plate A because plate B is composed of oceanic crust . For example : continents float over the asthenosphere (a layer below the lithosphere).
Hence, the correct answer is "A ".

Both the X- and Y-components of a vector are doubled. Which of the following describes what happens to the resulting Vector?
a) Magnitude increases by √(2
b) Magnitude increases by √(2, and the direction changes
c) Magnitude increases by 2
d) Magnitude increases by 2, and the direction changes
Answer: C. Magnitude increases by 2
Explanation:
If the magnitudes of X and Y vectors are increased, then the resultant vector will increase by a factor of 2 but the direction does not changes. Hence, option c is correct.
What is a vector ?A vector is a physical quantity having both magnitude and direction. For example, force, velocity, work done, momentum, velocity etc. are vector quantities. The quantities which does not have direction are called scalar quantity.
The resultant vector R of vectors in X and Y direction can be written as follows:
[tex]\rm R = \sqrt{x^{2} + y^{2}}[/tex]
If the x and y components are doubled to 2x and 2y then the resultant vector becomes,
[tex]\rm R = \sqrt{(2x)^{2} + (2y)^{2}}\\\\ R = \sqrt{4 (x^{2} + y^{2})\\\\\\ R = 2 \sqrt{x^{2} + y^{2} \\ \\ \\ \\[/tex]= 2R
Therefore, the resultant vector will increases by 2 times. However the direction will not change. Hence, option c is correct.

what are the main components of circulatory system and what is the function?
Answer:
Explanation:
The circulatory system is made up of blood vessels that carry blood away from and towards the heart. Arteries carry blood away from the heart and veins carry blood back to the heart. The circulatory system carries oxygen, nutrients, and hormones to cells, and removes waste products, like carbon dioxide.

Are noble gases nonreactive elements?
Answer:
Noble gases are nonreactive elements.
Explanation:
We call Group 18 of the Periodic Table "Noble gases" because they are inert gases. They do not like to bond with other elements.
The reason why is because their outermost shell for electrons is full. These electrons, called valence electrons, are are completely maxed out and therefore makes the element stable. This in turn makes it so that it doesn't really bond with other elements.
Answer:
Yes. Noble gases ARE nonreactive elements.

describing motion with position distance vs time graphs
Answer:
In a position-time graph, the velocity of the moving object is represented by the slope, or steepness, of the graph line. If the graph line is horizontal, like the line after time = 5 seconds in Graph 2 in the Figure below, then the slope is zero and so is the velocity. The position of the object is not changing.

Two technicians are discussing the FMVSS 135 standards for parking brakes. Technician A states that the hand force required to set the brake should not exceed 80 lb. Technician B states that the foot force to set the brake should not exceed 80 lb. Which technician is correct?
Answer:
Technician A
Explanation:
Technician A is correct because, the hand force required is not supposed and even should not exceed 80 lb.
On the other hand, the foot force limit is even higher at 100 lb. Thus, the required foot force break should not exceed 100 lb. We are given 80 lb in the question, which is quite less than 100 lb. It could exceed 80, but must not exceed 100. Thus only Technician A is correct among them both.
