The three observations that could help an individual in distinguising whether the organism is a fish or not is that it should live under water as fish can't survive without water, another thing is that it should laid eggs when it comes to giving birth because when it does not lay eggs but produces a living organism normally without an egg, it is considered to be a mammal and lastly, the appearance it possess such as having gils or fins.
The heart is a hollow cone shaped muscular pump within the thoracic cavity
The correct option is A.
An exponential growth is a type of growth whose rate becomes more rapid in relation to the total number that is available. When a specie has newly been introduced into a new area, they usually give birth rapidly and take over their new environment. If you check the options given above, you will see that it is only option A that have numbers that continuously increase. An exponential growth increase continuously. <span />
Answer:
100x − 200y = 600 and x + y = 12
Explanation:You can win the quiz show with 600 points. Remember that correct responses are worth 100 points and incorrect responses are worth -200 points. So, you need your total points from each correct response, x, minus your total points for each incorrect response, y, to equal 600:
100x − 200y = 600.
If you only respond to 12 questions, you need the total number of correct responses, x, plus the total number of incorrect responses, y, to equal 12:
x + y = 12.
Together, these two equations describe one way you can win.
