Answer:
Chemical and mechanical digestive systems.
Explanation:
Chemical and mechanical digestions are the two systems that are involved in the digestion of food. Some parts of digestive system broken down food with mechanical force such as mouth whereas some food is broken down into smaller substances with the help of chemicals such as juices of pancreas, liver, and intestine. Both systems are very important for the complete digestion of food particles into simpler substances in order to absorb by the cells to produce ATP.

Explanation:
Is a meander predominantly formed by erosion or deposition?
Answer:
Meanders change position by eroding sideways and slightly downstream. ... Thus by eroding its outer bank and depositing material along its inner bank, a stream moves sideways without changing its channel size. Due to the slope of the channel, erosion is more effective on the downstream side of a meander

Which adaptation below is a structural adaptation? A. Lions care for their young. B. Zebras form a herd and watch for predators. C. A bird builds a nest. D. A deer has flat teeth for chewing plants.
Answer:
D. A deer has flat teeth for chewing plants.
Explanation:
Adaptation, which is the ability of an organism to survive changes in its natural environment, can either be structural, behavioral and physiological. Structural adaptation is the possession of a physical or structural feature by an organism to enable it survive or adjust to change.
According to this question, the FLAT TEETH possessed by the deer for chewing plants is an example of structural adaptation because the deer posseses a structural feature (flat teeth) that allows it to feed on plants for survival.

Evaporites are chemical sedimentary rocks that form from the crystals that remain after water evaporation. Borax and gypsum are two examples of evaporite rocks. What is the FINAL step in the FORMATION process of evaporite sedimentary rocks?
Answer: Increase in compactness of the material.
Explanation:
Evaporites are the sedimentary rocks that are formed by the sediments and brines of the materials being degraded or withered from the parent and pre-existing rocks. The water is also lost from the withered material due to evaporation. The borax and gypsum also lose water to become evaporites and the increase in compactness due to loss of water molecules and increase in intramolecular forces between solid substances in the rock helps in sedimentation of the rock.

Explain how the respiratory system and circulatory system cooperate to provide the body’s cells with a constant supply of oxygen.
Answer:
In the respiratory system, you inhale oxygen which is transferred to the blood in the alveoli and circulated throughout the body. The blood in the circulatory system has a protein called hemoglobin which binds to the oxygen and carries it throughout the body. This oxygen is then given to the different cells for cellular respiration. It then carries the waste products (CO2) of cellular respiration back to the lungs and it is exhaled out.
Overtime organisms change sometimes they change so much of the sentence may be completely different for their ancestors what must happen for this process to occur
Answer:
In order to survive in the changing environmental conditions.
Explanation:
Changes occur in the body of an organism which make them different from their ancestors because these organisms evolve with the passage of time due to difference in environmental conditions. If these organisms can't evolve, they can't tolerate that environment and climatic condition and also become extinct so this process occur in the organisms in order to survive that different environmental conditions so we can say that this change is necessary in the organisms to survive.

Why do earthquakes occur near the San Andreas fault?
A
One plate slowly pushes the other plate up.
B) A trench is created as one plate slides under the other plate.
Portions of the plates get stuck and then suddenly loosen and move.
D
One plate pushes hard enough to reverse the motion of the other plate.
Answer:
C.
Explanation:
Basically a faster explanation is the san andreas fault is a transform boundary. If you have an oreo break one of the top pieces and slide them slowly it will get stuck causing an earthquake.
Earthquakes occur near the San Andreas fault because portions of the plates get stuck and then suddenly loosen and move. Hence option C is correct.
What is earthquake?Earthquake is defined as the abrupt release of energy in the Earth's lithosphere that causes seismic waves and causes shaking of the planet's surface. Earthquakes typically result from subsurface rock breaking unexpectedly and rapid movement along a fault. The seismic waves that cause the ground to tremble are brought on by this quick release of energy.
According to new University of Southern California research that contributes to the understanding of how earthquakes occur, tremors along a notorious section of California's San Andreas Fault seem to be fueled by thermal instability brought on by frictional shear occurring much deeper in the Earth than previously thought.
Thus, earthquakes occur near the San Andreas fault because portions of the plates get stuck and then suddenly loosen and move. Hence option C is correct.

4. The peppered moth lives on the trunks of trees in England. There are two colorations of this moth, light and dark, and both
are eaten by birds. A study found that prior to the Industrial Revolution, the number of light-colored moths found on the
trunks of trees was far greater than the number of dark colored moths. However, after the industrial Revolution, the numbers
were reversed
How would the genetic variation of the moths account for the change in the population sizes of each color? 50.7L152
A. The dark moths were able to kill off many of the light-colored moths, so their numbers increased a lot.
B. Natural selection caused the light species of moth to change into the dark species, allowing them to be better
hidden
C. After the industrial Revolution started, the light colored moths left the area to go live in another, less populated
environment
D. Natural selection favored the dark-colored moths because the factories were producing soot that landed on the
trunks of the trees.
Answer:
D.
I remember doing a question like this in class while learning about natural selection. The 2 colorations of moth live in a habitat that originally supported the lighter variant due to the light-colored trees. When the industrial revolution began, the soot levels reversed this because the black moths were more camouflaged that the lighter ones. A way we could prove this was the amount of black dresses and dark colored clothing during the time, often due to the fact that lighter colored clothing would turn black by the time the wearer arrived home. The lighter colored moths simply died off a bit because of this.

why are manure better than fertilizers
Manure is better than fertiliser. Manure is derived naturally and adds a lot more than just nutrients to the soil. They increase the activity of the microbes in the soil and increase its fertility. On the other hand, fertilisers harm these microbes and cause health issues in the consumers since they are synthesised chemically.

How are sedimentary rocks made. A. Magma or lava is cooled B. Materials are pressed together C. Chemical reactions change minerals. D. Earthquakes causes small pieces to fall
Answer:
B. Materials are pressed together
Explanation:
sedimentary rocks are made up of pieces (clasts) of pre-existing rocks. Pieces of rock are loosened by weathering, then transported to some basin or depression where sediment is trapped. If the sediment is buried deeply, it becomes compacted and cemented, forming sedimentary rock.
Sedimentary rocks are made up by the pressing down together the materials which are loosened through weathering. Thus, the correct option is B.
What are Sedimentary rocks?Sedimentary rocks are the type of rock which are formed by the accumulation or deposition of mineral particles or organic particles at the Earth's surface, followed by cementation of the particles.
Pieces of rock are loosened by weathering of particles, then these are transported to basin or depression where the sediment is trapped. If the sediment is buried deeply in the basin, it becomes compacted and cemented to form sedimentary rocks. Clastic sedimentary rocks may have particles of rocks ranging in size from microscopic clay to huge boulders.
Therefore, the correct option is B.

What will happen to levels of ATP in a muscle cell of an individual that stops consuming carbohydrates and other sources of sugar in his diet? Select ALL that apply 1. ATP production levels drop to 0 and the cell will die 2. ATP production will rise b/c the cell will use fat to make ATP. Fat has a lot more energy than carbohydrates. 3. ATP production levels will drop dramatically. Cell will have to import glucose from other cells. 4. ATP production will likely remain the same as the cell can use other compounds that feed into glycolysis and citric acid cycle. 5. ATP production will stay the same over a short time until all glycogen storage granules are depleted and then ATP production will stop.
Answer:
2
Explanation:
Fats are the slowest source of energy but the most energy-efficient form of food. Each gram of fat supplies the body with about 9 calories, more than twice that supplied by proteins or carbohydrates.
Have a great day <3
If the consumption of carbohydrates lowers, then ATP production will likely remain the same as the cell can use other compounds that feed into the glycolysis and citric acid cycles. Option 4 is the correct answer.
How is ATP produced from food?The dietary carbohydrates, protein, and fat are broken down to produce energy. The body generally uses glucose, as it is the simplest source of energy. Less energy is used to break down the glucose for energy.
From lipids and proteins, energy can be derived too. Lipids such as saturated lipids need more energy to break down the covalent bond. To generate energy from the lipid, the body must expend more energy. A lipid molecule generally produces 9 kcal of energy, while a carbohydrate molecule produces 6 kcal.
If the carbohydrate level decreases, the body will use the lipids to produce ATP. ATP production will not stop in the absence of carbohydrate until the body has lipid as a reserve material.
Hence, Option 4 is the correct answer as ATP will produce from other source.
