The primary source of heat for land and water is c. energy from the Sun as it is the only primary source of energy on earth.
How does water molecules get heated?When water molecules are heated, they change freely with the air in a procedure referred to as evaporation. Ocean water is continuously evaporating, growing the temperature and humidity of the encircling air to shape rain and storms which can be then carried through alternate winds.
Because water has a far better warmness capacity, or precise heat , than do sands, soils or different materials, for a given quantity of sun irradiation (insolation), water temperature will boom much less than land temperature.The heat supply for our planet is the solar. Energy from the solar is transferred thru area and thru the earth's surroundings to the earth's floor. Since this energy warms the earth's floor and surroundings, a number of it's miles or turns into solar energy .Read more about the temperature :

An oil mining company has started drilling oil offshore at a location. Thus far, it has benefitted the people by increasing employment opportunities in the area. Predict the most likely outcome the oil mine will have on the environment?
It will cause drying up of water in plants.
It will emit radiation which destroys plants.
It will produce greenhouse gases which pollutes soil.
It will contaminate the soil and water in the ocean.
Answer:
It will contaminate the soil and water in the ocean.
Explanation:
This is because the oil drilling will cause oil spillage on the soil and water in the ocean. The oil spillage will cover the oil and it will not allow plant to grow there. Any crops planted there will not grow because it had release chemical and act as covering which cannot support plant growth. When it is washed into the ocean or water bodies, it can lead to death if aquatic live because it will affect the amount of oxygen that will available to them.
Answer:
It will contaminate the soil and water in the ocean.

Track the evolutionary path of a butterfly and comment on it.
Answer:
The colorful canvas of the butterfly wing is an example of evolutionary innovation and adaptation. Compared with their ansestors, whose wings wore patterns of black, brown, and gray, the Lepidoptera (butterflies and moths) evolved a more varied palette of pigmentation.
I think it is very cool that they were able to evolve. For example, some butterflies use their bright colors to trick preators into thinking they are poisonous. The early butterflies could not do this.
Explanation:
Please brainliest!
Based on scientific information, the evolutionary path of a butterfly is primarily based on the origin of its species to eukaryotes and then to bilateria.
What is an evolution?An evolution refers to a biological and physical process that involves a gradual change in the characteristics and genetic make-up of the various species of organisms over several generations.
Based on scientific information, the evolutionary path of a butterfly is primarily based on the origin of its species to eukaryotes and then to bilateria such as:

1. A cool piece of iron gets warm when a red-hot piece of iron is placed a few inches
away. How is heat transferred in this scenario?
Answer:
Convection currents in the air between the pieces of metal transfer all the heat. The air between the two pieces of iron emits thermal radiation that is absorbed by the cool iron.
There you go, hope this helped.
Heat energy is transferred from one matter to another through various modes and methods. A cool iron piece heats due to convection that transferred the heat from the hot iron.
What is convection?Convection has been one of the modes of thermal heat transformation that uses matter to transfer the heat from higher to lower concentrations, unlike the radiation mode. The matter particles move from hot to lower temperatures.
The air present between the cold and hot iron piece acts as the medium by which the cold iron piece absorbs the heat transferred by the hot iron piece. This thermal energy is emitted and absorbed due to the difference in temperature.
Therefore, the process of convection facilitates the thermal heat transformation from hot to cold iron objects.

Explanation:
Compare and contrast negative and positive feedback loops. Which one is more common? Why?
Answer:
Negative Feedback LoopsA negative feedback mechanism or loop is a pathway stimulated by the deviation in the output, which causes changes in output to the direction opposite to the initial deviation.The negative feedback mechanism moves the variable factors towards the stable state or homeostasis after the control unit interprets the extent of the deviation.Negative feedback loops are more common than positive ones as they tend to stabilize the system.The loop detects the change in output and acts in the opposite direction to nullify the stimulus causing the change.These loops are activated under two conditions; when the value of the variable is above the normal value and has to be brought down and when the value of the variable is below the normal values and has to be brought up.Negative feedback mechanisms occur as a part of homeostasis to bring the variables back to their normal levels by counteracting the stimulus, causing the deviation in the first place.Like in a positive feedback mechanism, a negative feedback mechanism also contains different components that together help to maintain a stable state.Examples of Negative Feedback Mechanism
1. Regulation of blood glucose level
2. Temperature regulation
Positive Feedback LoopA positive feedback mechanism, as the name suggests, is a pathway that in response to a deviation in the output causes the output to change even more in the direction of the initial deviation.A positive feedback mechanism amplifies the deviations and brings state changes to the output.Positive feedback mechanisms are far less common than negative feedback mechanisms as it moves the body away from homeostasis.The process of positive feedback mechanism progressively amplifies the response as long as the stimulus is continued.The positive feedback loop can consist of either a single component that activates its own activity or several components with direct and indirect interactions.Positive feedback loops in biological processes are often observed in processes that need to occur quickly and towards completion as the output tends to increase the effect of the stimulus.Positive mechanisms are very few within living systems like the human body, but these can also be observed in the ecosystem, like in the case of ripening of fruit.Examples of Positive Feedback Mechanism
1. Menstrual cycle
2. Childbirth
Negative feedback loops are more common than positive ones as they tend to stabilize the system.
Positive Feedback vs Negative Feedback (8 Key Differences)Definition
The positive feedback mechanism is a pathway that in response to a deviation in the output causes the output to change even more in the direction of the initial deviation. A negative feedback mechanism or loop is a pathway stimulated by the deviation in the output, which causes changes in output to the direction opposite to the initial deviation.Effect on the homeostasis
A positive feedback mechanism breaks down the homeostasis system of the body. A negative feedback mechanism works to maintain the conditions of homeostasis in the body.Occurrence
The positive feedback mechanism is less common and occurs in specific situations.The negative feedback mechanism is more common and occurs in different organs and systems in the body.Stability
The positive feedback mechanism is less stable.The negative feedback mechanism is more stable.Effect
In a system with a positive feedback mechanism, the effective input is increased by the addition of actual input with the feedback signal.In a system with a negative feedback mechanism, the effective input is decreased as the feedback signal inhibits the actual input.External interruption
A positive feedback mechanism might require an external interruption.A negative feedback mechanism doesn’t require an external interruption.Changes
Positive loops enhances the change in physiological factors.Negative loops resists changes in physiological factors.Examples
Positive feedback mechanism in nature is observed during childbirth in humans and during the ripening of fruits. The negative feedback mechanism is observed during thermoregulation and maintaining the blood glucose level.__1. Where do FSH and LH get released from?

Walking sticks are insects that may have either a striped body or a body without stripes. In one region where these walking sticks live, the vegetation is a plant with needle-like leaves that resemble the walking stick’s striped body. According to natural selection, what would most likely result from an increase in walking stick predators in the region? (SC.7.L.15.2) A.walking sticks without stripes will reproduce faster B.walking sticks with stripes will become more common C.walking sticks will develop a new, spotted pattern for their bodies D.walking sticks will live on rare plant species rather than the dominant species
Answer:
B. Walking sticks with stripes will become more common.
Explanation:
The striped bodies of the walking sticks will help them camouflage in the plants. The predators will be more likely to kill off the unstriped walking sticks, leaving the striped walking sticks to grow in population and become more common.

NASA scientists use satellites to monitor two important factors that lead too landslides
Answer:
The most important factors that lead to landslides are the declivity of the terrain and the type of soil.
Explanation:
Stony soils are more prone to landslides, especially on steep terrain and without any type of vegetation cover. During heavy rainfall, these two factors can promote landslides that cause major disasters, as water is able to drag this soil violently. To prevent this from happening and people from being harmed, NASA has developed satellites, which capture rainfall data and monitor the slope and composition of soils, being able to see in advance areas that could be landslides. In this way, it is possible to develop strategies that prevent the landslide from happening.
