What is the primary organ of the nervous system
Answer:
The nervous system consists of the brain, spinal cord, sensory organs, and all of the nerves that connect these organs with the rest of the body. Together, these organs are responsible for the control of the body and communication among its parts.
Brain, spinal cord, retina, sensory neurons, ganglia, as well as nerves are the primary organ of the nervous system.
What is nervous system?Nervous system: a network of organized cells with the specific purpose of carrying electrochemical inputs from sensory receptors to the location where a reaction takes place.
Every living thing has the capacity to recognize changes in both its own surroundings and outside it. Changes in the inner environment include those in the posture of the head and limbs as well as those in the internal organs, whereas changes in the exterior environment include those in light, temperature, sound, motion, as well as odor. The nervous system's organs include the brain, spinal cord, retina, sensory neurons, ganglia, as well as nerves.
Therefore, brain, spinal cord, retina, sensory neurons, ganglia, as well as nerves are the primary organ of the nervous system.

When two continental plates of similar
densities collide,
A. they remain level since densities in both plates are equal.
B. they both push back down into the mantle
C. one plate rides over the other one and forms a trench
D.they buckle upward and form mountains
Answer:
D. They buckle upward and form mountains.
Explanation:
When two plates (either oceanic or terrestrial) converge and they are of similar density then they will crash into each other and form mountains. A great example of this is when India crashed into the Asian continent and the Himalayas were formed.
A 1.25 g sample of aluminum is reacted with 3.28 g of copper (II) sulfate. What is the limiting reactant?
2Al(s) + 3CuSO4(aq) = Al2(SO4)3(aq) + 3Cu(s)
Select one:
a. Copper
b. Aluminum sulfate
c. Aluminum
d. Copper (II) sulfate
Answer:
d. Copper (II) sulfate
Explanation:
Given data:
Mass of Al = 1.25 g
Mass of CuSO₄ = 3.28 g
What is limiting reactant = ?
Solution:
Chemical equation:
2Al + 3CuSO₄ → Al₂ (SO₄)₃ + 3Cu
Number of moles of Al:
Number of moles = mass/molar mass
Number of moles = 1.25 g/ 27 g/mol
Number of moles = 0.05 mol
Number of moles of CuSO₄:
Number of moles = mass/molar mass
Number of moles = 3.28 g/ 159.6 g/mol
Number of moles = 0.02 mol
now we will compare the moles of reactant with product.
Al : Al₂ (SO₄)₃
2 : 1
0.05 : 1/2×0.05=0.025 mol
Al : Cu
2 : 3
0.05 : 3/2×0.05 = 0.075 mol
CuSO₄ : Al₂ (SO₄)₃
3 : 1
0.02 : 1/3×0.02=0.007 mol
CuSO₄ : Cu
3 : 3
0.02 : 0.02
Less number of moles of reactants are produced by CuSO₄ thus it will act as limiting reactant.

Margarita set up three vials on a hot plate. She poured the same amount of
liquid into each of the vials, and then she turned on the hot plate. Which event
could be a significant source of error in her experiment?
Answer: Since the vials are filled the same, and are placed on the same hot pad, all the water will evaporate at the same time
Explanation:
The source of error in the experiment is the vials being filled the same, and placed on the same hot pad, all the water evaporating at the same time .
What are errors?Errors in chemical analysis result when there is a difference between observed value and the true value.If the magnitude of errors is large , it results in decrease in accuracy, reproducibility, and precision.
There are three types of errors:1) random error 2) systematic error 3) human error.The cause of random errors are difficult to quantify while the human errors can be minimized by taking a range of readings to reduce the error.
Errors while measuring boiling point may be human errors while noting down the boiling temperature or instrumental or systematic error if there is a fault in the thermometer.

Which of the following best describes the velocity of an object?
A B0 m/s
B 30 m east
C 30 m/s east
D 30 m/s2
Answer:
[tex]\boxed {\boxed {\sf C. \ 30 \ m/s \ east}}[/tex]
Explanation:
Velocity is the vector measurement of the change in position over time. A vector measurement means the answer must include a magnitude (numerical value) and a direction.
Here are some units of velocity:
m/s (meters per second) kph (kilometers per hour) km/s (kilometers per second)There are many other units, but m/s is the most common.
We can eliminate choice B and D, because the units (meters-m and meters per second squared-m/s²) are not for velocity.
We are left with choice A (30 m/s) and C (30 m/s east). Remember, velocity needs a number and a direction. C contains the direction east, so it must be the correct answer.

Given is a helium atom. Inside the nucleus , there are 2 protons denoted by blue colour and the other two are neutrons denoted by green colour
Chemical element helium has the atomic number 2 and the symbol He. It is the first member of the noble gas group in the periodic table and is a colorless, odorless, tasteless, non-toxic, inert, monatomic gas.Neutrons have no charge, protons have a positive charge, and electrons have a negative charge.One proton's positive charge and one electron's negative charge are equal.While electrons have essentially negligible mass, protons and neutrons each have a mass of 1.While electrons quickly revolve around the nucleus in fixed circular orbits, protons and neutrons are present collectively in the nucleus at its center.The nucleus, located in the heart of the atom, is home to protons and neutrons, which are heavier than electrons.Learn more about helium here:

An atom of hydrogen loses its electron. What is its charge
Answer:
When an atom of hydrogen loses its electron it becomes positively charged.
Hope it will help you........Final Answer: +1
Explanation/Reasoning:
Because hydrogen is an atom (not an ion), you'll write it as H (not H+). Hydrogen (H) has one proton and one electron, so if it loses its electron, it will only have one proton. Therefore, it becomes an ion of H+. This means that the charge will be +1.

law of conservation of matter

Explanation:
brainliest?
Answer: Hope this helps:)
The Law of Conservation of Mass dates from Antoine Lavoisier's 1789 discovery that mass is neither created nor destroyed in chemical reactions. In other words, the mass of any one element at the beginning of a reaction will equal the mass of that element at the end of the reaction. The law of conservation of matter states that in any given system that is closed to the transfer of matter, the amount of matter in the system stays constant. The law of conservation of matter says that in chemical reactions, the total mass of the products must equal the total mass of the reactants. French chemist A. Lavoisier laid the foundation to the scientific investigation of matter by describing that substances react by following certain laws. These laws are called the laws of chemical combination. Matter says that the amount of matter stays the same, even when matter changes form. Sometimes it may seem that matter disappears during a science experiment, but this law tells us that matter cannot magically appear or disappear, it simply changes from one form to another. Matter can change form through physical and chemical changes, but through any of these changes, the matter is conserved. The same amount of matter exists before and after the change—none is created or destroyed. This concept is called the Law of Conservation of Mass.

Whic statements explain why rocks weather at different rates? Check all that apply
Explanation:
Weathering occurs one of three ways: through physical processes such as freezing and thawing, because of live organisms whose roots break rocks or through chemical processes that occur when carbon dioxide in the soil and air and mixes with water and specific minerals in rocks to form a weak acid that reduces rocks into silt, soil and sediment.
Chemical weathering typically increases as temperatures rise and rain falls, which means rocks in hot and wet climates experience faster rates of chemical weathering than do rocks in cold, dry climates.
