Answer:
Nucleus is the structure present in the cells that directs the cell activities.
Explanation:
Nucleus is responsible for cell division also it has heredity material stored inside it in the form of DNA.
It also plays a very important role in the synthesis of particular enzymes as well.
Answer:
YY
Explanation:
It's co-dominate, meaning both traits show, but don't blend (Ex: Red + White = Red With White Stripes) (Ex: Blue + Red = Red With Blue Spots)
Hey mate, here is your answer
Three ways by which nitrates are transferred from the land to water are :-
Δ The roots of the legumes undergoes symbiotic association for the intake of nitrogen. They form nitrates. So these plants help in transferring solid nitrate to water nitrate
Δ Animal wastes has nitrates. So these nitrates along with rain water can go to rivers
Δ The lightening strikes contain nitrogen which is converted by plants during nitrogen cycle into nitrates which then eventually goes into water
EFFECT ON HUMAN HEALTH
The nitrates are good when eaten. They help in proper functioning of body parts. But its also harmful if its contain is too much. Nitrate and Methemoglobinemia. Methemoglobinemia, or blue-baby syndrome, is a condition caused by the inability of the blood to deliver enough oxygen to the body. It is the most well-known effect of exposure to elevated levels of nitrate in drinking water.
EFFECT ON ENVIRONMENT
Nitrate in water is too dangerous for animals in aquatic. They can die if they start consuming nitrates
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.
Explanation:
Answer:
The winter solstice in the Southern Hemisphere is June 20 or 21, while the summer solstice, the longest day of the year, is December 21 or 22.
So I think the answer is
<em><u>D) celebrate the summer solstice</u></em>
