In science class, Blaine’s teacher puts one glow stick in a cup of hot water and another glow stick in a cup of cold water. She asks the students to think about how the temperature of the water will affect the chemical reaction that occurs inside the glow stick once it is bent and starts to glow.
Which glow stick will be brighter once it is bent? Explain your answer.
Answers
Answer:
The glow stick that was in the cup of hot water will be brighter once it is bent. The production of more light is evidence that the chemical reaction in the glow stick is happening faster. The reaction happens faster, because increasing the temperature increases the rate of a chemical reaction.

The global population has increased immensely over the last two centuries. Humans use fossil fuels to do a variety of tasks from heating their homes to travel to production of everyday products. As the human population has increased, so have the global fossil carbon emissions.
Write a scientific explanation that describes total world carbon emissions in 2050 if the world’s population decreases to five billion people.
Claim:
Evidence:
Reasoning:
Answers
Answer:
The earth would eventually become become a brown and grey wasteland and the blue sky and rainbows and things like that will be rare rain would be highly acidic
Evidence: There are less people which means less cars will be driven less oil will be used etc. also fossil fuels are non renewable resource which means fossil fuels will be harder to find overall diving up prices of gas,heating,etc which might make Deter people from using fossil fuels and switching to something cheaper. At this point to people will dislike fossil fuels more then now.
Reasoning: I think people won’t like fossil fuels for 2 good reasons. First the driven up price. Second there will be noticeable effects from fossil fuels it 2050. It can make crops harder to grow which could lead to famine and a Recession because driven up food prices and it will hurt the economy. Towns will slowly flood. Arctic species will die so on. So a poor family’s that can’t afford food won’t spend more money on something that overall hurts them. They will despise people who use fossil fuels and it will become socially wrong. Civilization at that time might also be working on them self. Population decreased a major amount. Something bad happened. And if what ever caused the decline in population was caused by humans which there’s no way to tell, they might try to improve human habits try not to begin wars, work on helping each other, and most importantly don’t harm there plant.

4.) Which heats faster, land or sea?
5.) Compare the direction of air in sea breeze and land breeze.
Answers
PLS MARK ME AS BRAINLIEST
1.) As a result, warm air rises. Therefore, the warmer air over the land surface is rising. As the warm air over the land is rising, the cooler air over the ocean is flowing over the land surface to replace the rising warm air.
2.) a cool wind that blows from land to water. On clear, calm evenings, temperature differences between a body of water and neighboring land produce a cool wind that blows offshore. This wind is called a "land breeze".
3.) While sea breezes occur during the day, land breezes occur at night.
4.) Since land absorbs more solar radiation the land surface retains more heat as do the vegetation for energy. Thus, land surfaces warm more quickly than water.
5.) Sea breeze carries increased moisture, which it absorbs while blowing over a water body. A Land breeze is drier since it has no opportunity to absorb water from any source. Lastly, the sea breeze moves from the sea towards a land body. A Land breeze moves from land toward a water body, generally a sea or ocean.
Answer: 1.) During a sea breeze, the air moves from the sea towards the land. During the day, the land heats up faster than the sea. As a result, the air above the land becomes warmer, and it rises. The cooler air from the sea moves towards the land to replace the rising warm air, resulting in a sea breeze.
2.) During the land breeze, the wind blows from the land towards the sea. At night, the land cools faster than the sea. The air above the sea remains warmer and rises, and the cooler air from the land moves towards the sea, resulting in a land breeze.
3.) The sea breeze occurs during the daytime.
4.) Land heats up faster than water. This is because water has a higher specific heat capacity than land. Specific heat capacity refers to the amount of energy required to increase the temperature of a substance. Water requires more energy to heat up compared to land, which is why it heats up slower than land.
5.) During a sea breeze, the direction of air is from the sea towards the land. During a land breeze, the direction of air is from the land towards the sea.

Due to the fact that some homologous components can only be observed during embryonic development, embryology was crucial to understanding how a species has evolved.
Explanation:
The discipline of comparative anatomy known as embryology examines how vertebrate animals grow before giving birth or hatching. Similarities between embryos and adults can be evidence of shared ancestry. For instance, as seen in the figure below, all vertebrate embryos possess tails as well as gill slits.
The embryological stages of several creatures are very similar, pointing to shared ancestry.

Describe how the energy in gasoline changes form as it travels through a car engine. How does this compare to the way it changes form in an organism?
Answers
Answer:
Here the chemical energy in the gasoline is converted into heat (thermal energy), light, and sound and the burning produces gases. These heated gases inside the chamber expand, causing the piston to move. Thus, the thermal energy is converted to mechanical energy.
The internal combustion engine in the car converts the potential chemical energy in gasoline and oxygen into thermal energy which is transformed into the mechanical energy that accelerates the vehicle (increasing its kinetic energy) by causing pressure and performing the work on the pistons.
Explanation:
Answer:
Gasoline Vehicles Only about 12%–30% of the energy from the fuel you put in a conventional vehicle is used to move it down the road, depending on the drive cycle. The rest of the energy is lost to engine and driveline inefficiencies or used to power accessories.

D

Answers
Answer:
I believe the answer is A - Lions show their cubs how to hunt for prey. Hereidty is having the same genetics are your family member(s).
When lions show their cubs how to hunt for prey, it is not an example of heredity. Thus, the correct option is option A.
Heredity is the process by which features or qualities are passed down through genes from one generation (parent) to the next (offspring). Sexual reproduction is a fairly clear example of heredity. This is so because there is a lot of variety in the inherited traits during this phase.
Errors in DNA copying are the cause of the variance. Variation is significant because it supports heredity and aids in evolution. Gene mutations, how genes interact with the environment, and different genetic material combinations all contribute to variation. Keep in mind that variation can also be produced asexually. These differences, however, are barely perceptible.

What effect will the settling of sediment have on the shape of the stream?
Answers
The issue of sediment in aquatic environments has been a topic of concern for many decades. During the nineteen-thirties, erosion became a national issue because of the dust bowl and as a result the Soil Erosion Service was established. Since the nineteen-thirties, the study of sediment erosion, transport, deposition, and intrusion has increased exponentially in the United States. Considering all of the past and current research, it is difficult to focus on essential research, but with limited resources it is imperative to refine the topics and prioritize the necessary areas of study. The same scoping is also true for treatment practices. The best and most effective treatment should be used on the most critical habitat. Establishing this systematic prioritization is a challenging but substantive endeavor.
Answer:
Question was : The graph in part A shows how slow-moving water cannot carry large pieces of sediment. As water slows down on the inside of a curve, some of the larger pieces of sediment will settle out of the water. What effect will the settling of sediment have on the shape of the stream?
Answer:
The river will deposit sediment along the inside of a bend in the river. This deposition causes the inside of the curve to become shallower and move farther inward

( science, 5th grade lvl )
Answers
Answer: Respiration inhales oxygen gases and exhales carbon dioxide.
Explanation: Here, Oxygen enters the blood during inhalation, and carbon dioxide leaves during exhalation. This process is called Respiration. Air enters through the nose or mouth and goes through the nostrils, then the pharynx where two tubes are seen one for food and the other for air. From there it goes to the larynx, the voice box. Next air travels to the trachea(the windpipe) from which they get divided into left and right air tubes called bronchi. Smaller bronchi are called bronchioles. These end in tiny air sacs called alveoli. Exchange of gases takes place and revert back.
