Compare an elephant’s trunk with a person’s hand. How are they similar? How are they different?
Answers
Answer:
one way that they are different is that unlike us humans they don't have fingers on their trunk. one way that they are similar is that both use something to pick objects up.
Explanation:
hope this helps you!
Both the elephant trunk and human hands are used to grasp objects.
The Elephant's trunk is the part of the elephant that extends outwards from its face and enables the elephant to pick up things. It is quite similar to the human hands in the sense that it can be used to grasp objects.
However, human hands are made of fingers but the trunk of an elephant is just a long structure that has no fingers. Hence, it is different from the human hands.

Describe the path cereal takes from eating with the mouth to glucose in the body cells. (Note: For full credit, your answer must include complete sentences, at least 4 organs of the digestive system, 1 organ of the circulatory system and the process involved for going between the digestive and circulatory.)
Answers
Answer:
The digestive system converts the foods we eat into their simplest forms, like glucose (sugars), amino acids (that make up protein) or fatty acids (that make up fats). The broken-down food is then absorbed into the bloodstream from the small intestine and the nutrients are carried to each cell in the body.

What condition is required for piles of sediment to become a sedimentary rock?
1. Low force
2. High energy
3. High pressure
or 4. Low temperature
Answers
Sedimentary rocks are created by the accumulation of already existing rocks or fragments of extinct organisms on the Earth's surface, hence option 3 is correct.
What is a sedimentary rock?Weathering causes rock fragments to become loose, which are subsequently moved to a basin or depression where sediment is trapped.
Sedimentary rock is created when sediment is firmly buried and gets compressed and cemented. Large boulders to tiny clay particles have been found in clastic sedimentary rocks.
The process of erosion involves moving weathering products from the weathering site, either as solid material or as dissolved components, to finally be deposited as sediment.
Therefore, sediment is any unconsolidated accumulation of solid, weathered material to become a sedimentary rock that requires High pressure, hence option 3 is correct.

Answers
:
loook over ur notes promise youll find thrm
Human contributions to greenhouse gases in the atmosphere are warming the earth's surface - a process which is projected to increase evaporation of surface water and accelerate the hydrologic cycle. In turn, a warmer atmosphere can hold more water vapor.
Atmosphere
This process makes Earth much warmer than it would be without an atmosphere. The greenhouse effect is one of the things that makes Earth a comfortable place to live.
Cryosphere
By reflecting sunlight, ice and snow have a cooling effect on the climate. Removing the ice to leave darker land or ocean reduces this cooling and so amplifies climate change. Thawing permafrost releases significant amounts of greenhouse gases, causing further warming.

What factors determine the type of rocks that forms underground?
1.The amount of heat present
2.The amount of water present 2 out of 3 numbers are correct
or 3.The type of minerals that combine
Answers
Answer: the answer is (d)
Explanation:
The initial rocks that form an underground rock that was melted and the history of the molten rocks' cooling are the two main elements that affect the formation of igneous rocks.
What factors affect the rock's formation?
After a rock has been fractured, the fragments of rock and minerals are carried away by a process known as erosion.
The type of igneous rocks that form from magma depends on three factors, the chemical composition of the magma, the temperature at which solidification takes place, and the rate of cooling, which affects the crystallization process.
Therefore, factors determine the type of rocks that forms underground forces of weathering and erosion, and Magma's chemical makeup is subject to change.

ATP stores some of the energy from glucose molecules during glycolysis. How is the remaining energy from these glucose molecules released?(1 point)
Water
Heat
Electron Transport Chain
Carbon Dioxide
Answers
Answer:
Tha answer is Heat. It is NOT Electron Transport Chain. 100% positive!
Explanation:
The remaining energy from these glucose molecules released as heat.
So, second option is the correct answer.
How is the remaining energy from these glucose molecules released?
During fermentation, most of the energy that was not converted into ATP was trapped in the chemical waste product lactic acid or ethanol, and a small part of the energy was also released as heat.
During cellular respiration, about 41% of the energy in glucose is converted to ATP. Let's see how this value was calculated. From the information above, we know that in an ideal scenario, 1 molecule of glucose produces 38 molecules of ATP. In other words, 1 mole of glucose would produce 38 moles of ATP. Each mole of glucose contains 2870 kJ of energy, and each mole of ATP can release 30.7 kJ of energy. If we produce 38 moles of ATP, it can release a total of 1166.6 kJ of energy (38 moles x 30.7 kJ/mol = 1166.6 kJ). 1166.6 kJ is only about 41% of the total energy of 1 mole of glucose. What happened to the remaining 59% of the energy that was not converted to ATP? During cellular respiration, energy that was not converted to ATP was released as heat.
During fermentation, only about 2% of the energy in glucose is converted into ATP. Let's see how this value was calculated. From the information above, we know that during fermentation, 1 molecule of glucose produces 2 molecules of ATP. In other words, 1 mole of glucose would produce 2 moles of ATP. Each mole of glucose contains 2870 kJ of energy, and each mole of ATP can release 30.7 kJ of energy. If we produce 2 moles of ATP, it can release a total of 61.4 kJ of energy (2 moles x 30.7 kJ/mol = 61.4 kJ). 61.4 kJ is only about 2% of the total energy of 1 mole of glucose.
So,by the above theory,t is clear that the remaining energy from these glucose molecules released as heat.
