Answer;
Bones
Explanation;
The x-ray particles pass through the body. Structures that are dense such as bone will block most of the x-ray particles.
Different parts of the body absorb the x-rays in varying degrees. Dense bone absorbs much of the radiation while soft tissue, such as muscle, fat and organs, allow more of the x-rays to pass through them. As a result, bones appear white on the x-ray, soft tissue shows up in shades of gray and air appears black.

Which of the following is exclusively a natural resource of carbon dioxide?
A. Clearing land with fire
B. Coal Power Plants
C. Decomposition
D. Photosynthesis
Decomposition because using the process of elimination, you can see that photosynthesis uses CO2 therefoe, it isn't the answer. The other answers A and B aren't natural sources. That would leave Decomposition as the answer.
Decomposition is a process in decaying of rotting. The thermal decomposition of CO2 to CO and O2 is a possible way for the waste and utilization of CO2. However, this effect is confined by both the thermodynamic stability and the kinetic boundary. At 900 degrees C, this catalytic method achieves 100% of CO generation selectivity at 15.8% of CO2 changes.

Jack is learning to play the piano he knows that a piano has 88 keys and that there are 12 unique keys in each group called an octave how many complete octaves are on a piano
show work
math
All you would have to do for this is divide 12 by 88. So, 88/12 is 7.333333. That isn't a full number, which is probably what is confusing you. Although, since the question is asking for how many COMPLETE octaves on a piano, it would be 7 because there are 7 complete octaves, and a little more.
By dividing the total number of piano keys (88) by the number of keys in an octave (12), we find that a piano has 7 complete octaves.
To calculate the number of complete octaves on a piano with 88 keys, where each octave consists of 12 unique keys, we can perform a simple division operation. By dividing the total number of keys by the number of keys in an octave, we get the number of octaves:
88 keys \ 12 keys per octave = 7 octaves with 4 extra keys
Therefore, a piano with 88 keys has 7 complete octaves. The leftover 4 keys indicate that the piano does not have a complete eighth octave.

Wild salmon spend most of their lives in the ocean but return to freshwater rivers to spawn, or reproduce. Most wild salmon will only spawn in specific spawning grounds in the rivers in which they were born. The construction of hydroelectric dams in rivers has blocked the paths of some salmon returning to their spawning grounds. This has led to population declines. Which method would be most effective in preventing further wild salmon population declines caused by the construction of hydroelectric dams?
A.
constructing passageways next to dams to allow salmon to swim around blocked rivers
B.
establishing protected regions around wild salmon spawning grounds in specific rivers
C.
observing the migration patterns of wild salmon by tagging and tracking a small sample of fish
D.
monitoring genetic diversity by using netting to catch salmon and obtain genetic samples
Answer: A
Constructing passage ways near the dams to allow to salmon to swim around blocked rivers.
The construction of dams in rivers has blocked the path of some salmons returning to spawning grounds. The best way to overcome this is to make the passage ways near the dams to allow salmons to swim in areas which have blocked due to dams. So that salmons can returned to the spawning ground and can spawn which leads to increase in their population.
Answer and Explanation:
Answer: A
Constructing passage ways near the dams to allow to salmon to swim around blocked rivers.
The development of dams in streams has hindered the way of certain salmons getting back to bringing forth grounds. The most ideal approach to defeat this is to make the entry ways close to the dams to permit salmons to swim in regions which have impeded because of dams. So salmons can got back to the producing ground and can generate which prompts increment in their populace.

“Vesicles bud off the golgi or ER and fuse with the plasma membrane to expel their contents into the extracellular fluid”.... what type of active or passive transport is this?
Final answer:
Exocytosis, the process by which vesicles release contents outside the cell after fusing with the plasma membrane, represents an active transport mechanism that requires energy.
Explanation:
When vesicles bud off the Golgi apparatus or endoplasmic reticulum (ER) and fuse with the plasma membrane to expel their contents into the extracellular fluid, this process is known as exocytosis. Exocytosis is a type of active transport because it requires energy to move substances against their concentration gradient. This process is essential for various cellular functions such as removing undigested waste, secreting hormones, enzymes, and transporting substances across cellular barriers.
What is one way that calcitonin and parathyroid hormone maintain homeostasis?
The metabolism of calcium or calcium homeostasis refers to the procedure by which the body sustains appropriate levels of calcium. The bone functions as an essential storage place for calcium, as it comprises 99 percent of the overall calcium in the body.
The discharge of calcium from the bone is monitored by parathyroid hormone, and the incorporation of calcium in the bone is stimulated by calcitonin. When the concentration of the calcium in the blood elevates, the parafollicular cells of the thyroid gland enhance secretion of calcitonin in the blood.
At the similar time, the parathyroid glands minimize the secretion of parathyroid hormones into the blood. The resulting greater levels of calcitonin in the blood instigate the bone to withdraw calcium from the plasma of the blood and deposit it like a bone.
However, when the level of calcium in the blood is too low, the secretion of calcitonin is prevented and secretion of parathyroid hormone is stimulated. This leads to withdrawal of calcium from the bone to correct the levels of calcium in the blood.
Calcitonin is a hormone that is generated in humans by the parafollicular cells (unless identified as c-cells) of the thyroid gland. Therefore, repression of the osteoclasts straight diminishes the amount the amount of calcium discharged into the human blood. This is just a simple statement so now all you have to do is demonstrate what will befall when you connect calcitonin and parathyroid.
Explanation:Parathyroid hormone is concealed from parathyroid glands. Parathyroid hormone intensifies calcium levels in the blood when they are too low. Whereas as calcitonin is a hormone concealed by the parafollicular cells of the thyroid gland. It works antagonistically to the parathyroid hormone. This means that calcitonin decreases calcium levels in the blood when it is high.

thats easy just like james bond and indiana jones
im serious see its that similar yet different
A hydrogen bond is a strong form of a covalent bond. A covalent bond is one where two nonmetals share electrons. A hydrogen bond is where a hydrogen shares electrons with a very electronegative element, such as oxygen, nitrogen and fluoride.
you are planning a experiment to find out whether the rate at which water freezes depends on the shape of its container and identify the manipulate variable and the responding variable. list the other variables you would control.
Controlling variables would include the shape of the container, its volume (you should have several containers of the different shape but same volumes) and the ambient temperature that the container is inserted into (assuming that this temperature remains constant during the freezing process).

What do you notice about the products in cellular respiration and reactants in photosynthesis? Plz Halp
The reactants of one are the products to the other, the products of one are the reactants to the other. Opposites. I believe that is the answer.
Cellular respiration involves the reversal of the products and reactants of photosynthesis: Water and carbon dioxide, the byproducts of cellular respiration, serve as the reactants in photosynthesis. The byproducts of photosynthesis, oxygen and sugar, are the reactants in cellular respiration.
What products in cellular respiration and in photosynthesis?While photosynthesis utilizes carbon dioxide and releases oxygen, cellular respiration uses oxygen and creates carbon dioxide.We and the majority of other species use the released oxygen for cellular respiration.
The byproducts of cellular respiration include water, ATP, and carbon dioxide. Two carbon dioxide are created as acetyl-CoA is created from pyruvate.
Therefore, During the Krebs cycle, four more carbon dioxide are created. This carbon dioxide is circulated in the blood before being absorbed by the lungs.

3.Commercial development in the U.S. has resulted in an increase in the number of roads, housing developments, shopping centers, and parking lots. What risk does this pose to organisms in environments impacted by commercial development? A. Development often causes habitat fragmentation, which can threaten biodiversity. B. Development often causes reforestation, which can reduce the number of anthromes. C. Development often causes pollution, which can increase the ozone of the ozone layer. D. Development often causes biological magnification, which can increase global warming.
The correct answer is option A, that is, development often causes habitat fragmentation, which can threaten biodiversity.
Fragmentation is usually illustrated as a reduction in some of all the kinds of natural habitats in a landscape, and the differentiation of a landscape into smaller and more isolated segments. With the development of the fragmentation process, the ecological influences will modify.
Fragmentation can be a result of natural procedures like floods, fires, and volcanic activity, but it is more generally caused due to human activities like an increase in the number of roads, housing developments, shopping centers, and parking lots.
With the enhancement in human activities, the effect of fragmentation become more. Eventually, it results in the devastating influences on the local species, a complete modification to the landscape, and the loss of the region's wilderness heritage.

Explain three ways that grieving experiences may differ among individuals.
Each individual experiences grief in a distinct manner. Usually, a person experiences grief in cycles or waves. This means that there is the duration of painful and intense feelings, which come and go.
There are certain factors or ways by which an individual experiences grief. These are:
1. The association of a grieving person had with the person whose death had taken place.
2. The reason of death, that is, the process of grieving may differ on the basis of whether the person death has taken place suddenly or whether the person was ill for a longer time period.
3. Even the grieving experience is shaped by the individual's culture and society. Every culture has its own array of rituals or beliefs for bereavement and death. This also influences that how the individual encounters and experience grief.
A person's grieving experience may differ from others in expression, intensity, and length. One can hide grief or express grief openly to others. One may feel intense sorrow and loss during the grieving process, while others experience less intense feelings. The intensity of feelings may be influenced by one’s beliefs about death. Someone may also grieve for longer periods of time, while others overcome their grief in a shorter amount of time.
