Need help ASAP!!Which of the following sets of terms could be used in a description of the peripheral nervous system?

A) Motor neurons and sensory neurons

B) Brain and spinal cord

C) Motor neurons and brain

D) Sensory neurons and spinal cord

Answers

Answer 1
Answer:

Answer:

A) Motor neurons and sensory neurons

Explanation:

We can answer the question by answering the following questions

What is the nervous system?

  • Nervous system is a s system in the body that helps in the coordination between all the body parts and the brain which is the control center.

How is the nervous system classified?

  • The nervous system is classified into central nervous system and peripheral nervous system.

What comprises of the central nervous system?

  • The central nervous system is made up the brain and the spinal cord.

What comprises of the peripheral nervous system?

  • The peripheral nervous system is comprised of all the parts of the nervous system outside the brain and the spinal cord.
  • It includes the sensory neurons and the motor neurons.
  • Motor neurons transmits impulses from the brain to the effector cells such as muscles and glands.
  • Sensory neurons, on the other hand, transmit nerve impulses from the sensory organs to the central nervous system.

What happens to the Solar energy absorbed by plants during photosynthesis

Answers

Answer:

Plants, containing chlorophyll, undergo the process of photosynthesis. In this process, plants consume carbon dioxide and water, in the presence of sunlight, and convert it to glucose and oxygen. Thus, plants convert the light energy of the sun to the chemical energy of glucose.

What method of forecasting uses averages to predict future weather?O
A. Persistence method
B. Climatology method
O
C. Analog method
O
D. Trends method

Answers

The climatology method of forecasting uses averages to predict future weather.

Answer: B

Explanation

The satellites and advanced technologies have helped meteorologists to forecast accurately.

There are four types of forecasting methods prevailing now.

They are climatology method, persistence method, analog method and trends method.

The persistence and trends method uses the previous day forecast and compare with today's condition to forecast about future.

The analog method is a complex method where the forecasting is done by comparing present weather condition with a similar condition occurred in the past to predict for future.

The climatology is the simplest method which uses average of weather conditions observed in the previous days to get accurate forecast for future.

Climatology method is the right answer.

Trejo reacts 5.0 moles of hydrochloric acid (HCI) with 1.5 moles of barium hydroxide (Ba(OH)2). Which reagent is the limiting reagent and which is in excess?

Answers

the balanced equation for the above reaction is as follows
Ba(OH)₂ + 2HCl ----> BaCl₂ + 2H₂O
stoichiometry of Ba(OH)₂ to HCl is 1:2
number of Ba(OH)₂ moles - 1.5 mol
number of HCl moles - 5.0 mol
limiting reactant is fully consumed during the reaction and amount of product formed depends on amount of limiting reactant present 
excess reactant only a fraction of the amount present is used up in the reaction 
if Ba(OH)₂ is the limiting reactant 
if 1 mol of Ba(OH)₂ reacts with 2 mol of HCl 
then 1.5 mol of Ba(OH)₂  reacts with 2 x 1.5 = 3.0 mol of HCl
but 5.0 mol of HCl is present and only 3.0 mol is required 
therefore excess reagent is HCl and limiting reactant is Ba(OH)₂ 

Given the balanced equation representing a reaction:Al2(SO4)3 +6NaOH ==> 2Al(OH)3 + 3Na2SO4

The mole ratio of NaOH to Al(OH)3 is

(1) 1:1 (2) 3:1

(3) 1:3 (4) 3:7

Answers

The answer is number 2. 3:1. This is the simplified value of 6:2 which came from 6NaOH:2Al(OH)3. The original ratio is 6:2 but it can be simplified through dividing it each by 2. So 6 divided by 2 equals to 3 and 2 divided by 2 is 1. Therefore the simplified ratio is 3:1.
