When the Earth moves, the angle at which sunlight hits different places on Earth at the same time of day changes because the Earth is tilted.

Earth's rotation or Earth's spin is defined as the rotation of the planet Earth around its axis as well as the change in the orientation of the axis of rotation in space. When viewed from Polaris, the north pole star, the Earth rotates in the east facing east, the Earth rotates counterclockwise.

When the heading of the particular place is towards the Sun, there is warm temperature which is called as the summer when the heading of the same place is away from the Sun, there is cold temperature which is called as the winter.

Thus, when the Earth moves, the angle at which sunlight hits different places on Earth at the same time of day changes because the Earth is tilted.

Answer:

D. sulfur oxides from factories

Explanation:

This does not naturally occur, only if there is a factory. These other things happen on their own in nature but sulfur from factories relies on other factors down on earth.

sulfur oxides from factories is not a naturally occurring part of Earth's atmosphere.

EPA’s national ambient air quality standards for SO2 are designed to protect against exposure to the entire group of sulfur oxides (SOx).  SO2 is the component of greatest concern and is used as the indicator for the larger group of gaseous sulfur oxides (SOx).

 Other gaseous SOx (such as SO3) is found in the atmosphere at concentrations much lower than SO2.

Thus, sulfur oxides from factories is not a naturally occurring part of Earth's atmosphere.

Answer:

Climate change is rapidly becoming known as a tangible issue that must be addressed to avoid major environmental consequences in the future. Recent change in public opinion has been caused by the physical signs of climate change–melting glaciers, rising sea levels, more severe storm and drought events, and hotter average global temperatures annually. Transportation is a major contributor of carbon dioxide (CO2) and other greenhouse gas emissions from human activity, accounting for approximately 14 percent of total anthropogenic emissions globally and about 27 percent in the U.S.

Fortunately, transportation technologies and strategies are emerging that can help to meet the climate challenge. These include automotive and fuel technologies, intelligent transportation systems (ITS), and mobility management strategies that can reduce the demand for private vehicles. While the climate change benefits of innovative engine and vehicle technologies are relatively well understood, there are fewer studies available on the energy and emission impacts of ITS and mobility management strategies. In the future, ITS and mobility management will likely play a greater role in reducing fuel consumption. Studies are often based on simulation models, scenario analysis, and limited deployment experience. Thus, more research is needed to quantify potential impacts. Of the nine ITS technologies examined, traffic signal control, electronic toll collection, bus rapid transit, and traveler information have been deployed more widely and demonstrated positive impacts (but often on a limited basis). Mobility management approaches that have established the greatest CO2 reduction potential, to date, include road pricing policies (congestion and cordon) and carsharing (short-term auto access). Other approaches have also indicated CO2 reduction potential including: low-speed modes, integrated regional smart cards, park-and-ride facilities, parking cash out, smart growth, telecommuting, and carpooling.

Answer:

mutualism

Explanation:

Commensalism is best represented by this graph.

It is the interaction and the result of it between two organisms. It can be either positive negative or neutral.

It can be either mutualism, commensalism, amensalism, predation, parasitism, mutualism, symbiosis, etc.

It is the type of interaction in which one species is unaffected while the other benefits from the relationship

Since the population size of A is unaffected while the population size of B is increased (benefitted), we can say that it is commensalism

Secondary Consumer organism that consumes a primary consumer for energy.Tertiary Consumer organism that consumes a secondary consumer for energy. Therefore options "B" and "A" are correct.

Primary producers are known as autotrophs. They generate energy from the sunlight. The process by which they produce energy is known as photosynthesis. Examples of organisms are algae, bacteria, higher plants, and some protists. These organisms also store this energy.

Secondary producers are the organisms and animals which feed on the primary producers. After consumption, they convert it into energy. The energy generated is known as ATP. The process by which the energy is generated is known as cellular respiration.

A mutant protein is the protein product encoded by a gene with mutation. Mutated protein can have single amino acid change (minor, but still in many cases significant change leading to disease) or wide-range amino acid changes by e.g. truncation of C-terminus after introducing premature stop codon.

What is protein? ... Most animal sources of protein, such as meat, poultry, fish, eggs, and dairy, deliver all the amino acids your body needs, while plant-based protein sources such as grains, beans, vegetables, and nuts often lack one or more of the essential amino acids.
