Answer:
Muscle tissue and neural tissue
Explanation:
Excitability refers to the ability of muscle and nerve cells of the respective tissues to respond to a stimulus and generate an action potential. Both muscle cells and neurons respond to a stimulus and convert it into the action potential.
Action potential refers to the electrical signal. Propagation of action potential along the membranes of these cells results in muscle contraction and functioning of neurons.
The membrane potential of these cells changes in response to the stimulus and the changed potential is propagated to the other cells.

Answer:
Change in velocity: yes
Change in acceleration: no
Explanation:
The diagram of the problem is missing: find it in attachment.
In the diagram, there are represented:
- The velocity of the car, as a vector labelled with V
- The acceleration of the car, as a vector labelled with A
The directions of the vector represent the direction of the velocity and the acceleration, while the length of the arrows represent the magnitude of the two quantities.
We observe that:
- For the velocity, the direction is always to the right; however, the length of the arrow decreases, so the magnitude of the velocity keeps decreasing
- For the acceleration, the direction is always to the left; and the length of the arrow remains constant, therefore the magnitude of the acceleration does not change.
This means that the car is moving to the right, but it is slowing down, since the direction of the acceleration is opposite to the direction of the velocity.
Answer:
igneous rock CAN become sedimentary rock through a process called ROCK CYCLE.
Explanation:
Rocks can be defined as solid structures of minerals that are formed naturally over a period of time. They are grouped into three main types which includes the following:
- igneous rock
- sedimentary rocks and
- metamorphic rocks.
Rocks are capable of transforming from one type to another through a process known as rock cycle. There are two forces that brings about this process which includes:
- The internal force : this is the Earth’s internal heat engine, which moves material around in the core and the mantle and leads to slow but significant changes within the crust.
- The external force: this is the the hydrological cycle, which is the movement of water, ice, and air at the surface, and is powered by the sun.
Molten magma cools to form either extrusive igneous rock or intrusive igneous rock. With time they undergo weathering, eroded, transported, and then deposited as sediments which are being compressed and cemented into SEDIMENTARY ROCKS. Again through the above mentioned forces, different kinds of rocks are either uplifted, to be re-eroded, or buried deeper within the crust where they are heated up, squeezed, and changed into METAMORPHIC ROCK.
Therefore the material in this sedimentary rock found in Rhombus planet used to be in igneous rock deep in Rhombus's interior due to continuous rock cycling on the planet. I hope this helps
