1. State one possible negative effect of a warming trend on Earth. Specify how this effect will
have a negative impact on the living environment.
Answer:
One stated possible negative effect of a warming trend on earth is that the polar ice caps could melt.
Explanation:
Specification on how this will have a negative impact on the living environment is that it will cause sea levels to rise this is negative because: tsunamis will become more severe and damaging to land. Rain storms will have severe floods then what we have now.

Answer:
A close, interdependent relationship between two organisms is called SYMBIOSIS . There are three main types of symbiotic relationships. In MUTUALISM, both organisms benefit from the relationship. When one organism benefits but the other is harmed, their relationship is called PARASITISM. Occasionally, two organisms have a relationship where one organism benefits and the other is neither hurt nor helped. This type of relationship is called COMMENSALISM.
The type of relationship where one organism benefits and the other is neither hurt nor helped is called commensalism.
What is commensalism?In biology, commensalism is a connection between members of two different species in which one species uses the other for food or other purposes without causing the other any damage or gaining anything in return.
The commensal, or species that gains from the connection may take resources from the host species, which is unharmed, or find refuge, support, or means of movement. Frequently, a bigger host and a smaller commensal are in a commensal relationship.
The commensal species may exhibit significant morphological adaptation, whilst the host organism is virtually unaffected by the contact. Contrasting this connection with mutualism, which benefits both species,
A well-known illustration of a commensal is the remora (family Echineidae), a fish that travels in close proximity to sharks and other fish. Remoras have developed a flat, oval-sucking disc structure on top of their heads that cling to the bodies of their victims.
Remoras and pilot fishes both eat the leftover food from their hosts. Bird species like the magnificent egret (Ardea alba), which feeds on insects discovered by grazing animals or on soil creatures stirred up by plows, are other instances of commensals.
Therefore, this type of relationship is called commensalism.

Explanation:
Because it does not have a well defined nucleus and bound organelles
Answer:
B

Answer:
" Natural gas does not produce greenhouse gases as other energy sources do."
Explanation:
The answer, "Coal deposits are found on nearly every continent and mining coal poses few risks." shows only how it can be a better option, but does not show how it can benefit.
The answer, "Petroleum is relatively inexpensive compared to other forms of energy." only shows how it can be a better option, but does not show how it can benefit.
The answer, "Nuclear power increases water vapor in the atmosphere." does not clearly state how this benefits us.
-kiniwih426
Answer:
Petroleum is relatively inexpensive compared to other forms of energy.
Explanation:
Because:
"Natural gas does not produce greenhouse gases as other energy sources do." natural gas does produce greenhouse gases, including carbon dioxide and water vapor, the natural gas mostly releases the greenhouse gas.
"Coal deposits are found on nearly every continent and mining coal poses few risks." coal is inexpensive, but could be damaging to the habitats around the coal mining.
"Nuclear power increases water vapor in the atmosphere." nuclear powder doesn't really increase water vapor, but makes water vapor.
"Petroleum is relatively inexpensive compared to other forms of energy." it is inexpensive if compared to other fossil fuels. (aka, the most inexpensive)

carnivores such as a lion are able to kill their prey because of powerful jaw muscles. we humans do not need this power in our jaw muscles. which muscle is more powerful in the carnivore than the human?
The masseter muscle is more powerful in the carnivore than in humans as they functions vary.
The masseter muscle is present in carnivores such as lion, tiger etc. This jaw muscle help these animals to kill preys as it exerts a biting force of about 25kg when used on them.
They are important muscles for chewing. The muscle is positioned in a superficial quadrangular manner as a result of it originating from the zygomatic arch and they are also primarily responsible for the elevation and the protraction of the mandibles.

to allow movement of the tendons within the carpal tunnel zone, each tendon is encased in a __________.
To allow movement of the tendons within the carpal tunnel zone, each tendon is encased in a sheath.
The sheath is a fibrous but at the same time serous element that is composed of a viscous liquid called the synovium, which is designed in order to allow the tendons to move with the bones.
The function of the sheaths is to allow a correct sliding between the tendon where it meets the bone through which it passes.
The importance of sheaths for the biomechanics of movements is that if they were not located in the tendons, these tissues would wear out very easily, thus causing injuries such as tenosynovitis.
The best known synovial sheaths are those of the flexor apparatus of the hand, that is to say to the internal and external digitocarpal, in the fibrous band of the foot, and in the long tendon of the biceps muscle.
Therefore, we can conclude that to allow movement of the tendons within the carpal tunnel zone, each tendon is encased in a sheath.

I am able to fill a glass of water to the top and it does not overflow…which property of water allows this to happen
Answer: surface tension
Explanation:
Answer:
When we fill the glass with water, we notice right away that it can go over the brim of the glass without spilling. This is because of surface tension. Surface tension holds the water together and acts against what would normally cause the water to fall – gravity – because each molecule of water is attracted to the other water molecules around it.
Explanation:
extra facts Water molecules are attracted to each other and is why you can fill a glass and as it gets to the top it will stay together to a certain point. However that stick together ability is pretty mild so when gravitational forces take effect the bonds are broken and it flows down the sides of the glass. Unfortunately, the attraction between the water molecules is only so strong. As we add coins, the amount of water spilling over the edges is getting larger and larger until the water just can’t take it anymore! Gravity is pulling on too many of the molecules for their attraction to keep them up, and the water spills down the side of the glass.What to Do. Place the glass on the saucer and fill the glass of water all the way to the brim. You’ll notice that the water hangs slightly over the top of the glass but doesn’t spill out just yet. Now, add the coins one at a time to the glass of water, dropping them in rim-first (not face down).
Help please! Q: Location Three: Select three events that you predict will be observed. If I explore two continental plates at a transform boundary, then I will observe:
A: earthquakes
B: faults
C: ocean formation
D: mountains
E: volcanoes
F: island chains
G: seafloor spreading
Answer:
Earthquakes, Faults, and Island chains.
Explanation:
There are three types of plate boundary such as Constructive, destructive and transform plate boundary. The primary landform in the Transform boundary are faults which is caused by the Earthquakes. Many transform boundary landforms are in the ocean floor which is responsible for the island formation. Fault is found due to the two process such as Ridge push and ridge pull. Transform boundary neither creates and nor destroys any land in the region.
