How are the nervous systems of a flatworm and a fish different?

Answers

Answer 1

A flatworm has a simple nervous system with two nerve cords running down both of its sides. It also has two simple brains, and two eyespots that help sense light. While a fish's nervous system is comprised of a central brain and a spinal cord along with many branching nerves, which allows them to sense things around them.

Explanation:

A flatworm has a very mild nervous system with pair nerve cords moving down each side. It has two single brains called ganglia, which are pure packages of nerves. It has two eyespots that support it sense light. A flatworm has a gastrovascular hole with one opening.

Fish have extremely advanced nervous systems organized around a brain. Fish brains have rare clearly visible parts. Back to the brain is the spinal cord, which is the deep dorsal nerve cord that identifies chordates.

If you have a choice to earn simple interest on $10,000 for three years at 8% or annually compounded interest at 7. 5% for three years which one will pay more and by how much?.

Answers

Answer:

annually compounded interest at 7. 5% for three years will pay more by $22.97

Explanation:

Simple interest

A = P (1+ rt)

A = final amount

P = initial principal balance

r = interest rate

t = number of time periods elapsed

A = 10000(1+0.08x3) = $12,400

Annual compound interest

A = P (1+ r/n)^nt

A = final amount

P = initial principal balance

r = interest rate

n = number of times interest applied per time period

t = number of time periods elapsed

A = 10000(1+0.075/1)^(1x3) = $12,422.97

$12,422.97 - $12,400 = $22.97

There are different reasons why things happens. If differential heating did not occur on earth, then there no global warming or global cooling will take place in the atmosphere.

When the Earth flat surface is facing the sun, all its part of that surface would get the same level of incoming solar radiation but the fact remains that due to the Earth being spherical in shape, sunlight is therefore not distributed evenly over the Earth’s surface and as such all the regions of Earth will be heated to different degrees.

____________ reinforcement occurs if a behavior is only reinforced some of the time. A. Continuous b. Positive c. Intermittent d. Negative.

Answers

Answer:

Its c! Intermitted

Explanation:

I took the test

Intermittent reinforcement occurs if behavior is only reinforced some of the time. The correct option is c.

What is Intermittent reinforcement?

Delivering rewards at irregular periods is known as intermittent reinforcement. This technique has been shown to elicit the most effort from the subject.

The subject is rewarded at what appears to be random intervals, rather than every time they exhibit a desirable behavior or in accordance with any set plan. In order to enhance the trauma bond, which is the result of the victim's extreme emotional experience as she battles for her life and looks to the abuser for approval, intermittent reinforcement is used.

Positive reinforcement, negative reinforcement, extinction, and punishment are the four different types of reinforcement.

Therefore, the correct option is c. Intermittent.

Which shows the correct values for the variables in the table? a = 18, b = 34, c = 65 a = 34, b = 18, c = 68 a = 34, b = 68, c = 47 a = 47, b = 18, c = 68.

Answers

The values of a, b, and c from the table are 34, 18, and 68 respectively.

From the given table, the following equations are true;

number of subscribers above $25000 + number of those not subscribing above $25000 = 47

Set theory

Substituting the values:

a + 13 = 47

a = 47 - 13

a = 34

Similarly;

b + 55 = 73

b = 73 - 55

b = 18

Also, c = 13 + 55

c = 68

Hence the values of a, b, and c from the table are 34, 18, and 68 respectively.
