Answer:
try moving the circles into the empty ones displaying the damage
Explanation:
beats me i'm just trying to help
the answer to this is you have to show how sound waves get propagated from the cymbal to the ear.
when cymbal is hit(doesn't matter the force used to hit it) the energy dissipates and creates circular waves just like when a stone hits a pond.
A. I recommend drawing the cymbal dissipating circular wave from the energy of the hit.
B. as the circular wave propagates it creates compression and rarefactions. as sound wave reaches the air it displaces the air particle and if it happens to to several nearby air particles it creates compressions( lines that look like ||||) where there's high pressure a typical restoring force will cause the particle to move back to their original positiin creating low pressure region(| | |).
I think that's what you should draw.
C. when sound is received it comes with the compressions and rarefactions (||||| | | | ||||) which are high pressure and low pressure respectively. As high pressure reaches the eardrum it pushes it inwards and as the low pressure comes it pushes the eardrum outwards causing it to vibrate setting a vibrational motion. since the eardrum is attached to the bones of the middle ear, as the bones begin to vibrate then the sound wave-pressure wave-mechanical vibrations in the bones.
the vibrations are then transmitted to the fluid in the inner ear where they are converted to electric impulses and transmitted to the brain to be interpreted.
if the sound waves come more frequently then the eardrum vibrates more frequently and it can be interpreted as high pitch sound and if the intensity of the sound wave is high it is characterized by air particles with high amplitude and produce a forceful vibration in the eardrum and the brain will perceive it to be a high sound.
that's all I got hope it helps

Which factor is primarily responsible for location A
having a lower average yearly temperature
than location B?
(1) nearness to a large body of water
(2) elevation
(3) latitude
(4) prevailing winds
Answer:
Nearness to a large body of water
Explanation:
Nearness to a large body of water is primarily responsible for location A having a lower average yearly temperature than location B. Hence, option A is correct.
What are the factors affecting the temperature of an area?The horizontal distribution of temperatures refers to how the Earth's surface's temperatures are distributed throughout latitude. Isotherms display the horizontal distribution of temperature on Earth. Isotherms are line intersections where the temperatures are the same. Analysis of the isotherm map reveals that the temperature is unevenly distributed along its horizontal axis.
The troposphere's temperature drops as you ascend in height, although the rate at which it drops varies depending on the season.
Elevation, latitude, prevailing winds, ocean currents, and distance from the sea are some factors that affect the temperature of an area.

B) according to the law of superstition the youngest rock layers are at the bottom. C) The oldest known rocks on earth are approximately 4 million years old. D) earth is constantly changing.
Answer:
B
Explanation:
The law of superposition states that rock strata (layers) farthest from the ground surface are the oldest (formed first)
Hope this helps :)
The statement regarding the fossil and the rock layer that is false is that, according to the law of superposition, the youngest rock layers are at the bottom. In terms of the rock layer, option B is correct regarding the statement.
What are the fossils?The fossils are the preserved materials of the animals and plants, such as the skeleton, teeth, bones, imprints, and other parts stored in the different layers of the earth. These fossils are preserved in natural ways, not by humans, and they are helpful for the study of the different animals because some fossils give the idea of the connecting links, and they give the idea of the animals' living conditions in the early time.
Hence, the statement regarding the fossil and the rock layer that is false is that, according to the law of superposition, the youngest rock layers are at the bottom. In terms of the rock layer, option B is correct regarding the statement.

1pt Place the following steps in the correct order:
1. Sperm nuclear envelope breaks down
2. Genomes blend to form a diploid cell
3. Decondensation occurs
4. Sperm head penetrates egg cytoplasm.
Answer:
The delivery of the paternal genome to the egg is a primary goal of fertilization. In preparation for this step, the nucleus of the developing spermatozoon undergoes extensive morphological and biochemical transformations during spermatogenesis to yield a tightly compacted sperm nucleus. These modifications are essentially reversed during fertilization. As a result, the incorporated sperm nucleus undergoes many steps in the egg cytoplasm as it develops into a male pronucleus. The sperm nucleus (1) loses its nuclear envelope, (2) undergoes nucleoprotein remodeling, (3) decondenses and increases in size, (4) becomes more spherical, (5) acquires a new nuclear envelope, and (6) becomes functionally competent to synthesize DNA and RNA. These changes are coordinate with meiotic processing of the maternal chromatin, and often result in behaviors asynchronous with the maternal chromatin. For example, in eggs fertilized during meiosis, the sperm nucleus decondenses while the maternal chromatin remains condensed. A model is presented that suggests some reasons why this puzzling behavior exists. Defects in any of the processes attending male pronuclear development often result in infertility. New assisted reproductive technologies have been developed that ensure delivery of the sperm nucleus to the egg cytoplasm so that a healthy embryo is produced. An emerging challenge is to further characterize the molecular mechanisms that control sperm nuclear transformations and link these to causes of human infertility. Further understanding of this basic process promises to revolutionize our understanding of the mystery of the beginning of new life.

Answer:
A gene codes for a particular protein that is involved in the expression of a trait. Characteristics determined by single genes are called Mendelian traits.
