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.

Answers

The transformation performed by Karen is 90 degrees counterclockwise rotation across the origin.

The table is given as:

Original  point ---- Image

A (-4,-1)                  (1,-4)

B (-7,-6)                 (6,-7)

C (-14, -6)              (6,-14)

D (-11, -1)               (1,-11)

From the table, we can see that;

The coordinates are swapped, and the new x-coordinate is negated.

This represents 90 degrees counterclockwise rotation across the origin.

The rule of this transformation is:

[tex](x,y) \to (-y,x)[/tex]

i.e.

[tex](-4,-1) \to (1,-4)[/tex]

[tex](-7,-6) \to (6,-7)[/tex]

the table below shows the ages of houses to the nearest year in a neighborhood. using the age of the houses as the random variable, x, which graph shows the probability distribution, px(x), of a randomly chosen house?

Answers

Probability distributions are used to represent data and their probabilities

The table entry is given as:

Age of House      Number of Houses

1                                         15

2                                        20

3                                         25

4                                        30

Start by calculating the probability of selecting a house that has a certain age.

This is calculated as:

[tex]Pr =\frac{Number\ of\ house}{Total\ number\ of\ house}[/tex]

So, we have:

[tex]P(1) = \frac{15}{90} = 0.17[/tex]

[tex]P(2) = \frac{20}{90} = 0.22[/tex]

[tex]P(3) = \frac{25}{90} = 0.28[/tex]

[tex]P(4) = \frac{30}{90} = 0.33[/tex]

This means that the graph that represents the probability distribution must show that the probability of 1 is 0.17; 2 is 0.22; 3 is 0.28; 4 is 0.33.

Answers

Let a, b, c be the coefficients of the balanced reaction

a SF₄ + b O₂   ⇒   c OSF₄

The atom counts for each element among the reactants should be the same as with the products:

• S : a = c

• O : 2b = c

If b = 1, it follows that a = c = 2. So the balanced reaction is

Emma puts $10,000 in a simple interest account at a bank. She will earn $1,800 in 4 years. What is the annual interest rate for the account?.

Answers

Answer: 4.5%

Explanation:

A = P(1 + rt)

A = final amount

P = initial principal balance

r = annual interest rate

t = time (in years)

A = 10000 + 1800 = 11800

11800 = 10000 (1 + r4)

1.18 = 1 + 4r

4r = 0.18

r = 0.18/4 = 0.045 = 4.5%

The required annual interest rate is  4.5% for the account.

What is the simple interest?

Simple interest is defined as interest paid on the original principal and calculated with the following formula:

S.I. = P × R × T, where P = Principal, R = Rate of Interest in % per annum, and T = Time, usually calculated as the number of years. The rate of interest is in percentage r% and is to be written as r/100.

A = P(1 + rt) ...(i)

First, we have to find the final amount

Initial principal amount (P) =  $10,000

Time (t in years) = 4

A = P + S.I.

A = 10000 + 1800 = 11800

Substitute the values in the above formula (i),

11800 = 10000 (1 + r × 4)

1.18 = 1 + 4r

4r = 0.18

r = 0.18/4 = 0.045 = 4.5%

Therefore, the required annual interest rate is  4.5% for the account.

The domain of a function is the set of input values the function can take

The radical function is not given; so, I will provide a general explanation

Assume the radical function is:

[tex]f(x) = \frac{1}{\sqrt{12- 2x}}[/tex]

The denominator of the above function cannot be negative.

So, we express the denominator as follows

[tex]12-2x > 0[/tex]

Subtract 12 from both sides

[tex]-2x > -12[/tex]

Divide both sides by -2

[tex]x < 6[/tex]
