Urbanization can result in negative impacts on the environment. How can transportation methods be improved to reduce the impact of urbanization on the environment? (4 points)
Increase the number of travel lanes on roadways to allow for more vehicles
Limit the number and location of vehicle charging stations
Plan housing and business developments that are within walking distance to businesses and parks
Provide additional bus stops for people to save time instead of walking to work
The right thing to do would be to plan housing and business developments that are within walking distance of businesses and parks.
Effects of urbanizationUrbanization often requires the removal of forests for construction. Urban areas are usually also characterized by a copious number of vehicles on the road
These impact the environment negatively through pollution.
When housings are planned such that they are at trekkable distances to businesses, there would be fewer vehicles on the road and the impact on the environment will reduce accordingly.

What is global wind and how do winds help humans travel?
Global winds are winds that appear in belts that go all around the world. Like local winds, global winds are driven by unequal heating of the atmosphere. Since global winds blow west to east, it helps humans travel west to east.
How global winds influence climate?
Global wind belts and calm regions have an effect on, is that the berg winds blow from the east and die out as they are available close to the equator.
The westerlies blow from the west and move storms across u. s. The easterlies blow from the east and they cause stormy weather to occur once cold air forms this belt meets heat air of the westerlies.

Models are important in science. Some models are verbal models, which are full elaborate descriptions that can help someone visualize the concept. You have seen various visuals of Earths layers. Create a verbal model of
Earth
s interior. In your model, describe the following:
1. The main layers of Earths interior and the indirect evidence that helped us determine the layers.
2. The flow of matter in the mantle and in the core and the effects of that flow.
3. The source of thermal energy and how energy flows throughout the layers. (Hint: think of the cause of the convection currents)
The main layers of Earths interior are the inner core, the outer core, the mantle and the crust.
What is the indirect evidence that helped us determine the layers?Use of seismic waves is the indirect evidence that helped us determine the layers. When earthquakes occur they produce seismic waves.
The flow of matter occurs by convection. The dense crust subducts back into the mantle exert forces on crustal plates that then move, producing tectonic activity.
So we can conclude that The main layers of Earths interior are the inner core, the outer core, the mantle and the crust.

How do products and reactants of photosynthesis and cellular respiration relate?
Answer:
Photosynthesis converts carbon dioxide and water into oxygen and glucose. Glucose is used as food by the plant and oxygen is a by-product. Cellular respiration converts oxygen and glucose into water and carbon dioxide. Water and carbon dioxide are by- products and ATP is energy that is transformed from the process.

Plants must have nitrates to help them grow. what must happen to nitrogen for it to be usable by plants?
Answer:
Nitrogen Fixation
Explanation:
Nitrogen is converted from atmospheric nitrogen (N2) into usable forms, such as NO2-, in a process known as fixation.
Plants must use nitrates in a form of nitrogen, which is needed to make proteins for healthy growth.
What impact on plants due to depletion of nitrates or nitrogen?Nitrate plays a very important role in our ecosystem such that due to presence of nitrogen plants grow fastly and produce fruits of bigger size flowers too.
Plants absorb nitrates from water through their roots without nitrates, the amount of chlorophyll in leaves reduces.
Nitrate is a common inorganic ion found in plants which is required for proper growth and development of the plant and growers include the percentage of nitrates in their nutrient requirement to starts plant growth. Plants acquire nitrate through root intake from the soil and water around them.
Hence due to decreasing percentage of nitrogen plants are getting yellowed it means it produces smaller fruit.
In modern era farmers add nitrogen containing fertilizers which produce large amount of grains, foods and fruits which is also diseases free.
Therefore,Plants must use nitrates in a form of nitrogen, which is needed to make proteins for healthy growth.

4. Which of the following is a parasite?
(a) Mushroom
(b) Fungi
(c) stem
(c) Cuscuta
(d) haustoria
(d) Rhizobium
Answer:
C: Cuscuta is a parasite .
Explanation:
Mushrooms are a part of the fungi domain meaning that it is a decomposer. I'm not too sure whether it means stem body cells or a stem in a plant. Either way both are not parasites. Cuscuta is a plant that does not have chlorophyll (they can't carry out photosynthesis) and since this plant cannot make its own food, it feeds off a host plant that can make food. An organism that needs a host to survive is called a parasite. Haustoria is a part of some parasites however it itself is not one. And finally Rhizobium is a bacteria that converts Nitrogen into ammonia which helps plants.

When minute samples of DNA need to be genetically analyzed for identification purposes, which test can be effectively used to make more of the DNA
Answer:
When minute samples of DNA need to be genetically analyzed for identification purposes, which test can be effectively used? Fluorescent dye can be used as a label to trace antibody-antigen reactions in an ELISA assay
DNA is the genetic material that is the unit of inheritance. Small DNA samples can be increased in amount by the technique called PCR. Thus, option D is correct.
What is PCR?Polymerase chain reaction (PCR) is the technique used in biotechnology to quantitatively increase the amount of genetic material. It has been known to create billions and millions of copies of the sample.
The small DNA sample can be amplified by the process of PCR which involves the production of the DNA sample by the polymerase and primers to add the bases to the strand.
The DNA undergoes thermal cycling where the temperature of the system first increases in denaturation followed by a drop in temperature in annealing and lastly again a rise of temperature in extension.
Therefore, the PCR technique can increase the amount of small DNA samples.

How does sea level change when Earth's global temperature is lower?
A. Glaciers grow bigger, causing sea level to fall.
B. Glaciers grow smaller, causing sea level to fall.
C. Glaciers grow smaller, causing sea level to rise.
D. Glaciers grow bigger, causing sea level to rise.
Glaciers grow smaller, causing sea level to rise when Earth's global temperature is lower. Thus, the correct option is C.
Sea level lowers during cold climate periods, known as glacial epochs or ice ages, due to a shift in the global hydrologic cycle, in which water evaporates from the oceans and is stored on the continents as massive ice sheets, extended ice caps, ice fields, and mountain glaciers. At the last glacial maximum, some 20,000 years ago, global sea level was about 125 meters lower than it is today.
What is interglacial epochs?Because the melting North American, Eurasian, South American, Greenland, and Antarctic ice sheets returned their stored water to the world's oceans as the climate warmed, sea level rose. Sea level is at its highest during the warmest eras, known as interglacial epochs.
We are currently living in the most recent interglacial, which began around 10,000 years ago and is referred to by geologists as the Holocene Epoch. Sea levels were about 3 to 20 meters higher than they are now during several previous interglacials.
