Explain how the parts of the peripheral nervous
system work with the central nervous system to
produce a response to the stimulus
Answer: receptors in the skin stimulate sensory neurons
Sensory neurons send messages to the central nervous system
Interneurons send messages to the motor neurons in response to messages received from sensory neurons
Motor neurons cause muscles in the leg to contract and pull the foot away
Explanation:
To produce a response to the stimulus, receptors (sense organs, muscles, glands, etc.) receive stimuli from the environment and from inside your body.
How peripheral nervous system works with the CNS?To produce a response to the stimulus the central nervous system processes information, it is the information that is received from the peripheral nervous system.
After that, the central nervous system sends this processed information to the peripheral nervous system. The peripheral nervous system sends a signal to the body part that needs to respond so you can react appropriately to the stimulus.
Therefore, if you accidentally step on a sharp object with your bare foot the peripheral nervous system work with the central nervous system to produce a response to the stimulus through receptors.

kinds of chemical changes using substances she found in her kitchen
so she could see these changes. Which of the following can occur when
a chemical reaction takes place? Choose the three statements that
apply.
Answer:
ABC
Explanation:
Lets say baking soda and vinegar when they react there is a chemical reaction where bonds break and from changing it into a new compound no longer just baking soda and vinegar.
The processes of diffusion and active transport are both used to * break down molecules to release energy move molecules into or out of cells of the body bring molecules into cells when they are more concentrated outside of the cell move molecules against a concentration gradient, using ATP molecules
Answer:
move molecules into or out of cells of the body
Explanation:
Majorly, there are two types of transport used by living cells. These are; passive and active transport. Passive transport involves the movement of molecules down a concentration gradient without the need for energy (ATP) input. Example is DIFFUSION AND OSMOSIS.
On the other hand, active transport is a type of transport that moves molecules against a concentration gradient (low to high) with the aid of energy input (ATP). Example is sodium-pottasium proton pump.
Although there are obvious differences between these two processes (diffusion and active transport), but they both MOVE MOLECULES INTO OR OUT OF CELLS OF THE BODY.

Answer:
D
Explanation:
I think so
1. Coriolis effect would deflect the path of the air mass to the west.
2. A horizon would provide the best assessment of the fertility of a soil.
3. Label E is located above Label D.
4. A La Niña can be described as cooler than usual waters in the tropical Pacific
The correct options for 1, 2, 3 and 4 are B, B, D and B respectively.
The Coriolis effect is the deflection of moving air (or an object) due to the Earth's rotation. The air moving in the northern hemisphere is deflected to the right of its intended path due to the Coriolis effect. As a result, in the Northern Hemisphere, air masses traveling from high to low latitudes will be deflected west.
The A horizon, commonly known as the topsoil, contains the most organic matter and nutrients, making it the most fertile layer of soil. This is the layer in which organic components such as degraded plant matter and humus interact with mineral particles to provide an optimal environment for plant growth.
The location at latitude D, which lies above the equator and parallel to the top of the Hadley cell, is where you might expect to find the driest average conditions in the Hadley cell circulation pattern mentioned in the question (north of the equator). Due to the compression, the air in the Hadley cell becomes warm and dry as it descends, resulting in arid or desert-like conditions.
La Niña is a climate phenomenon that causes cooling of sea surface temperatures in the central and eastern tropical Pacific Ocean. It represents the inversion phase of the El Niño–Southern Oscillation (ENSO) cycle.
Therefore, the correct options for 1, 2, 3 and 4 are B, B, D and B respectively.

(50pts) The evolution of the peppered moth over the last two hundred years has been studied in detail. Originally, the vast majority of peppered moths had light coloration. However, because of widespread pollution during the Industrial Revolution in England, the dark colored moths became much more common.
Question:
What specifically caused the shift in phenotype of the moths? Please explain in detail.
Answer:
The peppered moth is a temperate species of night-flying moth. Peppered moth evolution is an example of population genetics and natural selection and not artificial selection.
Explanation:
Answer:
The phenotype of the moth changed due to natural selection. During the Industrial Revolution, objects in England became a lot darker in color due to the settling of coal pollutants in the air. These light colored moths did not have good camouflage in this environment. Therefore, most of the light colored moths did not survive to reproduce. However, the dark colored moths had better camouflage, and were therefore more likely to survive and reproduce. This lead to a shift towards darker color moths, as they had a higher survival rate than the light colored moths.
where a mutation would take place in an organism
Answer:
The genome is composed of one to several long molecules of DNA, and mutation can occur potentially anywhere on these molecules at any time. The most serious changes take place in the functional units of DNA, the genes. A mutated form of a gene is called a mutant allele.
Explanation:
Answer:
DNA
Explanation:
Mutations occur in the nucleotide sequence of DNA
If the DNA is: TAC CGA CCG ACC TTA. Create a mRNA strand with a point mutation that would “not affect” the protein.
Answer:
AUG GCU GGG AGG AAU
Explanation:
A point mutation that would not affect the protein is one that has the same mRNA codon. The answer choices indicate that the third part is affected. The normal mRNA would be GGC, which if you look at the table, is gly. The other sequences that match are GGU, GGC, GGA, and GGG. The only answer choice that matches is the third one, with GGG.
choose the correct statement about the earth crust A. the earth crust is thin and could be compared to an eggshell B. most of the earth crust is only 6 km deep C. the earth crust is around 200 km deep D. the earth crust is the thickest layer
''A. the earth's crust is thin and could be compared to an eggshell'' is the correct answer.
Why earth's crust is considered an egg shell?The egg is considered a tiny model of the Earth. The thin shell of the egg represents the Earth's crust which is divided into plates. Both earth and egg have a thin and brittle shells. The crust of the earth is broken into various pieces like the cracked shell of a boiled egg. The mantle of the earth is like the egg white part whereas the core of the earth is present in the center like the egg yolk. The earth's crust is broken into pieces that geologists called it plates. The inside of the planet earth is layered like an egg. Scientists considered the surface of the Earth to be cracked like a big eggshell. They call these pieces tectonic plates that cover the Earth. The plates float slowly on the surface and sometimes crash with each other, and move away from each other.
So we can conclude that option A is the right answer about the earth's crust.

During which phases of the cell cycle are chromosomes composed of two chromatids?
Answer:
The correct phases are S phase, prophase, anaphase.
Explanation:
The cell cycle, the sequence of events spanning the period from the completion of one cell division to the end of the next division, involves both the division of the cell nucleus (karyokinesis) and the division of the cytoplasm (cytokinesis). S phase, the next section of the interface, is marked by a dramatic increase in DNA synthesis and the synthesis of histones which are major cellular proteins bound to DNA. The cell is preparing for the start of mitosis. Chromosomes duplicate lengthwise, and each chromosome consists of two identical "chromatids."During prophase, the degree of packing of the chromatin increases, so the chromosomes become shorter and thicker and the centromeres begin to become visible. Each of the chromosomes, due to its duplication in S phase, is made up of two identical chromatids, called sister chromatids. Anaphase is the short phase, the sister chromatids begin to separate and migrate to the poles. Once the two chromatids separate, each is called a chromosome.
