I am from Miami and I have been here for 6 yrs
Explanation:
Hbu?? : )
I don't know what you the answers provided are if you can comment i'll be glad to help you :)
With the given information we can calculate instatenous speed and average speed
To calculate instantaneous speed, we need to divide part of the total distance traveled by time. However, we don't want to use the distance of the entire trip, because that will give us average speed.
Average speed = Distance / time
Velocity = displacement/time
Displacement. = v × t
English translation of the question is as follows:
Analyze the alternatives below and check the one that does NOT describe a nervous system function. 1 point
a) capture and interpret stimuli from the environment.
b) carry information.
c) creating responses through movements, sensations or findings.
d) transport nutrients and oxygen to the body.
e) control the activity of the muscles.
Answer:
d) transport nutrients and oxygen to the body.
Explanation:
Nervous system functions to communicate with other cells through synapses and through membrane-to-membrane transfer that allows rapid transmission of signals that controls muscle activity and create responses through movements, sensations or findings.
Nervous system do not function to transport nutrients and oxygen to the body.
Hence, the correct option is "d)".
Answer:
The radial symmetry animals get information through their receptor cells and neurons present all over their body.
Explanation:
Radial symmetry animals can be cut in different directions. The central axis separates it into 2 equal halves and again it can be cut into 4 directions.
e.g. Hydra, sea urchin, starfish, etc
They are invertebrates have sense organs, but these sense organs are not well defined. Each symmetry of the body has sense organs. These radial symmetry organisms have oral and aboral parts.
Sea urchins, starfishes, Hydra are light sensitive. They possess photoreceptor cells in their epithelial linings. Starfishes also sensitive to touch, light, and temperature. Their spines and tube feet have motor nerves, which control their movement.
Eyespots in starfishes also help in detecting objects. It is composed of epithelial cells and responds to light. They lack a brain but have a complex nervous system. This nervous system consists of a sensory nerve and motor nerve. It spreads all over the body. Hence starfishes can react according to the stimuli.
