Write a short paragraph to describe viscosity. Include at least two examples of fluids and the words “flow,” “fluid,” “particles,” and “viscosity.”
Answers
Answer:
Viscosity is the resistance of a fluid (liquid or gas) to a change in shape or movement of neighbouring portions relative to one another. Viscosity denotes opposition to flow.
Explanation:
Answer:
Viscosity is the resistance of a fluid to flow (thickness or thinness of a fluid). Fluids with high viscosity do not flow as easy as fluids with a low viscosity. Temperature affects viscosity, the warmer the liquid, the faster the particles flow and the colder it is the slower it flows. For gases when temperature increases, less friction occurs so it the flow rate is higher and when its col the opposite thing happens

DNA replication begins when the double helix untwists and breaks in half between the nitrogen bases. What are the next two steps in the process of DNA replication?
Answers
Answer:
Step 1: Before DNA can be replicated, the double stranded molecule must be “unzipped” into two single strands. ... Step 2: Primer Binding. The leading strand is the simplest to replicate. ... Step 3: Elongation. ... Step 4: Termination
The DNA gets unzipped during DNA replication after the double helix unwinds. Each original DNA strand acts as a template for the new strands when the strands are split in two. The bases on either half of DNA are then paired with the nitrogen bases that have sugar and phosphate. In order to adhere to the principle of base pairing and guarantee that the base sequence is maintained, the molecules present in the new strand must be complementary to those found in the original strand. DNA replication ends with the formation of two identical strands.

some differences. Compare them below by writing each
characteristic in the correct location. You will use each only

• home to many types of grazers
• experience all seasons of weather
• home to bison
• home to the African elephant
• example: tallgrass prairies of North America
• example: Serengeti in Tanzania
• also known as tropical grasslands
• few trees due to little rainfall
1)
(Savannas)
(Both Types of
Grasslands)
(Temperate
Grasslands)
Answers
Answer:
S - Savannas are typically found in tropical or subtropical regions.
S - Savannas tend to have more trees and shrubs.
S - Savanna's climate is drier than that of a grassland.
G - Grasslands are found in temperature regions.
G - Temperature Grasslands are mainly devoid of trees, receive less rainfall than Savannas & endure broader temperature extremes.
G - Grasslands make up 25 percent of the Earth's land surface and dominate in regions with limited rainfall, which prevents forest growth. This results from nearby mountain ranges that cause rain shadows over adjacent open-range lands.
B - Both represent the world's richest and most diverse ecosystems. They both provide a home for a quarter of the world's population and a habitat for thousands of plants and animals.
B - Many species gather in vast numbers, graze on the varied grasses, and can be found nowhere else on Earth. The coexistence between wildlife and grasses is key to healthy ecosystems. Animal migrations regenerate the landscapes, by controlling pests, dispersing seeds, and trampling invasive species. Through this partnership, grasslands and savannahs generate vital benefits for both people and nature.
B - Ecosystems such as these two in specific are essential for climate mitigation – they store carbon, locking it deep in the soil and extensive root systems. They are the source of or support many of the world’s biggest rivers and wetlands, ensure food security, support livelihoods, and are embedded in the cultural identity of millions of people.
(Also, A savanna or savannah is a mixed woodland-grassland<---similarity)
Explanation: Just research. I decided to state 3 characteristics for both The Savanna and The Grasslands, and then 3 for "B" (both).

Johanna is explaining to her friend how to determine the climate of an area. Which instruction is she most likely to give her friend
A) measure the highest and lowest temperatures in a particular year
B) find the average weather conditions over a period of many years
C) measure the weather conditions one day and compare them to other days
D) record the precipitation and the wind speed for several months
Thank you!
Answers
Answer:
B) find the average weather conditions over a period of many years.
Explanation:
Johanna is most likely to instruct her friend to find the average weather conditions over a period of many years to determine the climate of an area.
Climate is defined as the long-term pattern of weather in a particular area, and it is typically calculated using weather data compiled over a 30-year period. This includes information such as temperature highs and lows, precipitation rates, and other weather elements.
By analysing these long-term averages, variations, patterns, and extremes, one can accurately portray an area's climatic character.

4. People throw away tons of garbage everyday. How can we reduce the amount of garbage?
5. Do you drink bottled water? Why or why not? What is its effect on the environment?
pls 3-5 sentence and then explain briefly the answer. ty
Answers
Answer:
1. There's air pollution, water pollution, noise pollution, and light pollution. The worst pollution is air pollution because it can cause severe health problems like respiratory diseases or even cancer.
2. Fossil fuels are resources that are formed from the remains of dead plants and animals. An example would be coal, oil, and natural gas. These fuels are used to generate electricity, power vehicles, heat homes and buildings. Yes, there many other energy sources that can replace fossil fuels.
3. One way to prevent factories from dumping waste water in rivers and oceans is to implement stricter regulations and penalties for those who violate them.
4. One of the best ways to reduce the amount of garbage is to reduce, reuse, and recycle.
5. Yes, I drink bottled water because it's more water to drink from a bottle and its effect on the environment is recycling and being reused.
1. Pollution can be of many types such as air pollution, water pollution, noise pollution, and land pollution. In my opinion, air pollution is the worst because it affects people's health and can cause breathing problems, heart diseases, and even cancer. Discussing this issue in a group can help us understand different perspectives and find solutions to reduce pollution.
2. Fossil fuels are non-renewable sources of energy that are formed from the remains of dead plants and animals. Examples of fossil fuels include coal, oil, and natural gas. They are used to generate electricity, fuel vehicles, and heat homes. However, they are a major contributor to air pollution and climate change. Fossil fuels can be replaced by renewable sources of energy such as solar, wind, and hydro power.
3. Factories dumping waste water in rivers and oceans can have a negative impact on aquatic life and the environment. To prevent this, factories can treat their waste water before discharging it into the environment. Governments can also enforce strict regulations and penalties for factories that violate environmental laws.
4. To reduce the amount of garbage, we can follow the three R's - reduce, reuse, and recycle. We can reduce the amount of waste we generate by using reusable bags, bottles, and containers. We can also compost organic waste such as food scraps and yard waste. Recycling can also help reduce the amount of garbage by turning waste into new products.
5. I try to avoid drinking bottled water because it generates a lot of plastic waste that can take hundreds of years to decompose. Plastic waste can also harm wildlife and pollute the oceans. Instead, I use a refillable water bottle and fill it with tap water. Tap water is safe to drink in most developed countries and can be a more sustainable choice.
