Transverse waves are always characterized by particle motion being perpendicular to wave motion. A longitudinal wave is a wave in which particles of the medium move in a direction parallel to the direction that the wave moves.
Answer:
The given statements are True.
Explanation:
The particle of the matter through which a wave move or travels is called medium. The mechanical waves can be distinguished into three types on the basis of the movement of the medium when the energy of the mechanical wave passes through, are: transverse, longitudinal, and surface waves
A transverse wave: perpendicular to the direction that the wave
A longitudinal wave: parallel to the direction that the wave

Co..me up with your own example of a stimulus and response with living organisms
.
Answer:
A crocodile goes into the shade when the temperature goes high.
An example of a stimulus and response with living organisms is as follows:
Whenever any living organism is exposed to a warm or hot object it immediately pulls back its own body from this point of contact. This is also called as reflex action. What is a Stimulus?A stimulus may be defined as a type of thing or event that immediately provokes a specific functional reaction by an organ or tissue in response to a specific treatment.
The information that living organisms perceive from the external world is sensed by the sense organs then with the help of nerves it sends to the brain which stimulates a specific action and sends messages to the body to react in a particular way with the respect to the stimulus.
Therefore, an example of a stimulus and response with living organisms is briefly mentioned above.

review the micrographs of cells shown in figure 8-3. what information about cells do these micrographs suggest, which might not be accurate?
Answer:
The micrographs of cells shown in figure 8-3. what information about cells do these micrographs suggest is explained below in details.
Explanation:
Micrographs are the intensified images collected from small microscopes. Cell micrographs are often obtained from tissue specimens and show a constant mass of cells and inside compositions that are difficult to distinguish individually. It provides accurate images of the exteriors of cells and whole plants that are not imaginable by TEM. It can also be practiced for particle counting and size resolution, and method control.
Which statement is NOT true about fluids?

B. liquid and gases are included
C. some take the shape of their container
D.particles move easily past each other
Answer:
option D is correct
Explanation:
The statement which is not true about fluids is particles move easily past each other.
What do you mean by Fluids?Fluids may be defined as any liquid or gas or generally any material that experiences a continuous change in shape when subjected to any object.
The properties of fluids indicate that all fluids can flow depending upon their densities. Some take the shape of their container due to fluidity. Fluids comprise liquid and gases.

How does the number of valence electrons in sodium (Na) compare to the number of valence electrons in calcium (Ca)? A. Na has two fewer valence electrons than Ca. B. Na and Ca have an equal number of valence electrons. C. Na has one more valence electron than Ca. D. Na has one fewer valence electron than Ca.
Answer:
D. Na has one fewer valence electron than Ca.
Explanation:
Elements in different groups has been grouper based on the number of valence electrons they possess. Valence electrons refers to the electrons at the outermost part of the shell of an atomic element.
Sodium (Na) belongs to group 1 on the periodic table meaning that it has one number of valence electrons while Calcium (Ca) belongs to group 2 meaning that it has two number of valence electrons. Hence, Na has one fewer valence electron than Ca.

where do veins always go
Answer:
Capillaries connect the arteries to veins. The arteries deliver the oxygen-rich blood to the capillaries, where the actual exchange of oxygen and carbon dioxide occurs. The capillaries then deliver the waste-rich blood to the veins for transport back to the lungs and heart. Veins carry the blood back to the heart.

John and Sarah had a child born with cystic fibrosis, a genetic disease. Both John and Sarah were normal, showing no signs of this disorder. How is it possible for them to have a child with this disease?
a. Cystic fibrosis must be a dominant trait disorder hidden in both parents' genotype, but not showing in the phenotype, that could be passed on to offspring.
b.Cystic fibrosis must be a recessive trait disorder hidden in both parents’ genotype, but not showing in the phenotype, that could be passed on to offspring.
c. Cystic fibrosis must be a dominant trait disorder hidden in one parents’ genotype, but not showing in the phenotype, that could be passed on to offspring.
d.Cystic fibrosis must be a recessive trait disorder hidden in one parents’ genotype, but not showing in the phenotype, that could be passed on to offspring
Answer:
B
My logic:
I did a whole project on genetics and i love genetics. I know for a fact this is the correct answer because i had it 2 years ago on a test and got it correct. On the off chance im wrong, it has been 2 years and i might have mixed my facts up.
Hope this helps!
Answer:
it is b
Explanation:
reccesive doesn show in the phenotype because its covered by the dominant trait so the parents were fine but it is both parents so that the kid has an rr and not Rr or RR so that the reccesive trait would be covered by the dominant in the phenotype so B
how does the cytoskeleton help maintain cell shape?
Answer:
Of the three types of protein fibers in the cytoskeleton, microfilaments are the narrowest. ... Microfilaments also provide some rigidity and shape to the cell. They can depolymerize (disassemble) and reform quickly, thus enabling a cell to change its shape and move.

Marcus is hanging a porch swing on his front porch. The first thing he has to do is attach two springs to the ceiling. Then, he fastens the
swing to the springs so that they can stretch and support the weight of the swing. Which two types of potential energy do the springs have?
A. elastic
B. gravitational
C. kinetic
D. stretched
The two types of potential energy that the springs have when Marcus hangs the porch swing on his front porch are (A)elastic potential energy and (B)gravitational potential energy.
The elastic potential energy is stored in the springs due to their deformation from their natural state. The gravitational potential energy is stored in the swing due to its height above the ground, which is determined by the position of the springs.
When Marcus attaches the springs to the ceiling, the springs are stretched and deformed from their natural state. As a result, they store elastic potential energy. This energy is proportional to the amount of deformation, which in turn is proportional to the weight of the swing and the distance the springs are stretched.
When Marcus fastens the swing to the springs, the gravitational potential energy of the swing is determined by its height above the ground. The higher the swing is from the ground, the greater its gravitational potential energy. The swing's height is determined by the length of the springs and their position relative to the ceiling
Therefore, the correct answers are A. elastic potential energy and B. gravitational potential energy.

During an experiment, if you purposely change the temperature to test a hypothesis, the temperature is called the a. manipulated variable. b. responding variable. c. hypothetical variable. d. dependent variable.
Answer:
Option a (manipulated variable) would be the appropriate choice.
Explanation:
To analyze the influence on something like a dependent variable, another modified variable seems to be an important variable responsive to modifications in quite an analysis. Plainly defined, the variable has been adjusted to determine its effect on the overall outcome of the study. There would be only one manipulated component in a correctly planned analysis.The other options offered are not relevant to the situation described. So, the solution above is the best one.
