Chordates have closed circulatory systems, centralized nervous systems, internal skeletons, notochord, and, tail.
Arthropods vs Chordates
Arthropods are similar to chordates in that they are both triploblastic and bilaterally symmetrical, among many other features.
However, chordates show more evolutionary advancement over arthropods in terms of:
possession of a closed circulatory system instead of an opened one found in arthropods.possession of a centralized nervous system.possession of internal skeletons that do not require shedding before growing, unlike arthropods with exoskeletons.possession of a dorsal hollow nerve cord that develops into the brain and spinal cord in some chordates. possession of a tail.More on chordates can be found here: https://brainly.com/question/8124743

How do matters differ and what explains that differences?
What is matter?
~ Matter is something which all physical objects are believed to be made of -- it is a material substance that occupies space, possesses mass, and is made up mostly of atoms (basic unit of matter) which consists protons, neutrons, and electrons, that constitutes the observable universe.
The states of matter~ State of matter is the distinction or the difference in forms of matter we can observe in our daily life. The 5 states of matter thus far are; solid, liquid, gas, plasma, and bose-einstein condensate.
DifferencesMatters differ in characteristics, appearance and compositions. Written here are the basic differences in 3 most fundamental states of matter.
Solid - a matter which composed of rigid and closely packed particles -- particles move only via vibrations. Has definite shape and definite volume.
Liquid - particles can move back and forth, not too tightly packed -- has definite volume but with no definite shape.
Gas - the particles in gas are relatively far apart compared to solid and liquid, they're moving fast back and forth/side to side, and bouncing nonstop. Gas neither have definite shape nor volume, and is way compressible than solid and liquid.

Which of these is the most likely consequence of rising petroleum prices?
A. Increased interest in public transportation
B. Falling transportation costs
C. Lower gasoline prices
D. Less demand for electric cars
Answer: Increased interest in public transportation
Explanation: got it right
Due to public transportation, more vehicles need more petroleum, leading to an increase in petroleum prices, hence option a is correct.
How are petroleum prices rising?Petroleum prices are likely to have risen as a result of both increased demand and worries about supply interruptions. Global demand for oil has been rising, exceeding any increases in supply and surplus capacity.
One major reason is that developing countries, particularly China and India, have been quickly rising. These economies have grown more industrialized and urbanized, contributing to an increase in global demand for oil.
This is because transportation costs will rise, raising the prices of numerous commodities. This is cost-push inflation, as opposed to inflation produced by increased aggregate demand excess growth.
Therefore increased interest in public transportation, leads to rising petroleum prices, hence option a is correct.
