Answer:
TRUE
Explanation:
Central to the functioning of the nervous system is an extensive network of specialized cells called neurons, There are basically two major types of nerves: sensory and motor. Sensory nerves send information such as touch, temperature, and pain to the brain and spinal cord., Sensory neurons carry nerve impulses from tissues and organs to the spinal cord and brain. Motor neurons carry nerve impulses from the brain and spinal cord to muscles and glands(see Figure below). Interneurons carry nerve impulses back and forth between sensory and motor neurons.

What is brain?The brain, spinal cord, and a sophisticated nerve network are all parts of the nervous system. The brain and the body are communicated with via this system.
All bodily functions are managed by the brain. From the brain, the spinal cord descends via the back. It is made up of strands of nerves that branch out to every organ and area of the body.
The brain sends and receives messages via this network of nerves to many regions of the body.

Use complete sentences to explain how global wind patterns such as the trade winds in the northern hemisphere would be impacted in the
absence of the Coriolis Effect.
Answer:
Coastal currents are affected by local winds. Surface ocean currents, which occur on the open ocean, are driven by a complex global wind system. To understand the effects of winds on ocean currents, one first needs to understand the Coriolis force and the Ekman spiral.
If the Earth did not rotate and remained stationary, the atmosphere would circulate between the poles (high pressure areas) and the equator (a low pressure area) in a simple back-and-forth pattern. But because the Earth rotates, circulating air is deflected. Instead of circulating in a straight pattern, the air deflects toward the right in the Northern Hemisphere and toward the left in the Southern Hemisphere, resulting in curved paths. This deflection is called the Coriolis effect. It is named after the French mathematician Gaspard Gustave de Coriolis (1792-1843), who studied the transfer of energy in rotating systems like waterwheels. (Ross, 1995).

make an essay about the importance and conservation of energy sources...
I need it :))
Answer:
mark me brainlist if i help:)
Explanation:
First of all, energy conservation plays an important role in saving non-renewable energy resources. Furthermore, non-renewable energy sources take many centuries to regenerate. Moreover, humans consume energy at a faster rate than it can be produced. Therefore, energy conservation would lead to the preservation of these precious non-renewable sources of energy.
Energy conservation will reduce the expenses related to fossil fuels. Fossil fuels are very expensive to mine. Therefore, consumers are required to pay higher prices for goods and services. Energy conservation would certainly reduce the amount of fossil fuel being mined. This, in turn, would reduce the costs of consumers.
Consequently, energy conservation would strengthen the economy as consumers will have more disposable income to spend on goods and services.
Energy conservation is good for scientific research. This is because; energy conservation gives researchers plenty of time to conduct researches.
Therefore, these researchers will have more time to come up with various energy solutions and alternatives. Humans must ensure to have fossil fuels as long as possible. This would give me enough time to finding practical solutions.

Which organelle makes the proteins that are needed by the cell? cell membrane Golgi apparatus ribosomes nucleus
Answer:
c)ribosomes
Explanation:i hope this helps
Ribosomes are the organelles responsible for protein synthesis in the cell and the correct option is option 3.
Ribosomes play a crucial role in translating the genetic information stored in the DNA into functional proteins. Ribosomes can be found in both prokaryotic and eukaryotic cells and are either free-floating in the cytoplasm or attached to the endoplasmic reticulum.
During protein synthesis, ribosomes read the messenger RNA (mRNA) molecule and assemble amino acids in the correct sequence to form a protein chain. This process occurs through a series of steps, including initiation, elongation, and termination. The ribosomes provide the site where these steps take place, ensuring that the proteins are synthesized accurately and efficiently.
While other organelles, such as the nucleus and Golgi apparatus, play important roles in the overall process of protein production and modification, it is the ribosomes that directly synthesize the proteins based on the instructions encoded in the mRNA molecules.
Thus, the ideal selection is option 3.

Why do most plants appear green?
Answer:
Most plants appear green because they absorb all other colors of light and reflect back green into our eyes. Since chlorophyll molecules use the red (opposite of green) end of the visible light spectrum to complete photosynthesis, then red is most heavily absorbed.
Chlorophyll gives plants their green color because it does not absorb the green wavelength of white light which is the light wavelength reflected from the plant, so it appears green.
What is Chlorophyll?The green color of many plants and algae is due to chlorophyll. Chlorophyll is defined as concentrated within organisms in structures called chloroplasts.
It is the green pigment in plants, algae and cyanobacteria that is essential for photosynthesis. The central structure is an aromatic porphyrin or chlorinated porphyrin ring system with a chelated magnesium atom.
Chlorophyll is formed in several different forms where chlorophyll a and b are the major types found in higher plants and green algae; Chlorophylls c and d are found mainly with a in various algae while the Chlorophyll e is a rare type found in some golden algae and bacterio-chlorophyll is present in some bacteria.
Thus, Chlorophyll gives plants their green color because it does not absorb the green wavelength of white light which is the light wavelength reflected from the plant, so it appears green.

What is the porosity of the sand sample?
A)
99%
B)
72%
C)
34%
D)
16%
Answer:
C) 34%
The other two samples are-
Gravel- D) 38%
Silt- B) 53%
Explanation:
To find the porosity of the sample, you do (volume of fluid)/(volume of substance) X 100. We were given a 300mL sample of sand, and 400 mL of water. You must also take account of how much surface water is found, which you add to however much water you put into the 300mL sample.
Gravel has the highest permeability, and silt has the lowest.
The porosity of the sand sample is 34%. The range of the porosity of sand particles lies between 25-50%. Thus, the correct option is C.
What is Porosity?Porosity is a measure of the void spaces in a material. It is a fraction of the volume of voids over the total volume of the system, which lies between 0 and 1, or as a percentage between the range of 0% and 100%. Strictly speaking, some tests measure the accessible void, and the total amount of void space which is accessible from the surface.
Sand is the largest mineral particle and it has more pore space which is between the particles of silt or clay. Silt particles are smaller than that of sand, but larger than that of clay particles. Likewise, there is less pore space or void space between the silt particles than that between sand particles, but more than between the clay particles.
Therefore, the correct option is C.
