Which two systems does the nervous system work with to direct behavior
and movement? *
O digestive and respiratory
muscular and skeletal
O excretory and digestive
circulatory and digestive

Answers

The muscular and skeletal system because we use our brain to move our body it sends a signal to move that muscle that we want to use

To solve this we must be knowing each and every concept related to nervous system. Therefore, "the muscular and skeletal system " is the correct option.

What is nervous system?

The nervous system serves as a link between the environment and the organism's interactions. The nervous system coordinates actions or sensory information by sending and receiving signals to and from various sections of the body.

The peripheral and central systems are the two sections of the nervous system. They aid in the appropriate step-by-step coordination of the many physical reactions and communications from the parts of the body to the brain and back. The muscular and skeletal system, the nervous system work with to direct behavior and movement.

Therefore, "the muscular and skeletal system " is the correct option.

moles in 9.01x10^23 molecules water

Answers

Answer:

The answer is 1.50 moles

Explanation:

To find the number of moles in a substance given it's number of entities we use the formula

[tex]n = \frac{N}{L} \\ [/tex]

where n is the number of moles

N is the number of entities

L is the Avogadro's constant which is

6.02 × 10²³ entities

From the question we have

[tex]n = \frac{9.01 \times {10}^{23} }{6.02 \times {10}^{23} } = \frac{9.01}{6.02} \\ = 1.496677740...[/tex]

Explanation:

Chemical properties are those properties that tell us about what a substance can do as regards to whether or not the substance reacts with other substances.

Examples are flammability, rusting of iron, precipitation, decomposition of water by an electric current.

The ability to decompose and reactivity are chemical properties of a substance.

Physical properties tells us everything about what a substance is when no change is occurring to its constituents. Examples are state of matter, color, odor, taste, texture, hardness e.t.c

Knowing that vinegar is a solution of ethanoic acid (CH3COOH) and water, this student decided to take a 25.0 cm3 sample, dilute it with 25.0 cm3 of water and then react it with sodium hydroxide. The dilute sample required 37.0 cm3 of 0.850 mol dm–3 sodium hydroxide solution to react entirely with it via the following reaction:

.What threatens the newly hatched chicks?

Answers

Answer:

rats. that's all i know of Just about everything except the mother hen if they are natural hatch. Even when you incubate them there are threats. The healthy chicks will mob the weak ones, the older chicks (even by a day) will pick on the younger ones. Temperature extremes will threaten them as they need warm, humid conditions with gradual drops in surrounding temps in the brooder box. Early disease is sometimes a problem and all chicks should be started on medicated chick feed for the first few weeks to prevent several digestive diseases. Even the water dispenser can be a threat as newly hatched chicks will immerse themselves in an open water container so care should be taken to supply water in a self feeding covered dish.

If an unknown sample contains 39.04% sulfuric acid by mass, then a 0.9368 g of that sample would require _____ mL of 0.2389 M NaOH for neutralization.
A) 31.22
B) 39.98
C) 7.80
D) 79.96
E) 15.61

Please give an answer and an explanation, thanks!

Answers

Answer:

A) 31.22

Explanation:

The reaction of sulfuric acid with NaOH is:

H₂SO₄ + 2 NaOH → Na₂SO₄ + 2H₂O

To solve this problem we need to determine the moles of acid that will react, and, using the chemical equation we can determine the moles of NaOH and the volume that a 0.2389M NaOH solution would require to neutralize it.

Moles H₂SO₄ (Molar mass: 98.08g/mol):

0.9368g * 39.04% = 0.3657g H₂SO₄ * (1mol / 98.08g) =

3.7289x10⁻³moles H₂SO₄

And moles of NaOH that you require to neutralize the acid are:

3.7289x10⁻³moles H₂SO₄ * (2 moles NaOH / 1 mole H₂SO₄) =

7.4578x10⁻³ moles NaOH

Using a 0.2389M NaOH solution:

7.4578x10⁻³ moles NaOH * (1L / 0.2389mol) = 0.03122L = 31.22mL

Right answer is:

A) 31.22
