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.

Please help me, I don't understand this
mihalych1998 [28]

Answer:

4, based on the assumption that the R allele is dominant over the r allele, and that the T allele is dominant over the t allele.

Explanation:

Any bush with a dominant petal color allele (R) will have red petals. This includes Rr and RR.

Any bush with a dominant bush size allele (T) will have a tall bush. This includes Tt and TT.

The only way to acquire a short bush or pink petals is to have two recessive alleles together (tt, rr).

RRTT, RrTT, RRTt, and RrTt -> red petals with tall bushes

RRtt, Rrtt -> Red petals with short bushes

rrTt, rrTT -> pink petals and tall bushes

rrtt-> pink petals with short bushes.

These are the four phenotype variations possible in this dihybrid cross.

Why is the axis important for seasons?
Bezzdna [24]
If the earth wasn't spinning , we wouldn't have summer, winter, fall, spring etc, it is important because we need the sun for certain seasons and no sun for others.

Why must the formulas of hydrates have the number of water molecules as whole number integers?
Sphinxa [80]

The formula for hydrate indicates the number of water molecules that are attached to each formula unit of the compound. Forexample, nickel (II) sulfate hexahydrate is a green/blue solid that has six water molecules included in the crystal foreach Ni2+and each SO42-ion.Many common minerals are

<h3>What is a hydrate ?</h3>

Any compound containing water in the form of H2O molecules, usually, but not always, with a definite content of water by weight.

  • The best-known hydrates are crystalline solids that lose their fundamental structures upon removal of the bound water.

  • Hydrates are formed when water and light end natural gases come into contact at certain temperature and pressure conditions
