The first groups of land plants to evolve were liverworts, mosses, and hornworts. These plants were small and grew close to the ground because they relied on water being able to move on its own through the plant bodies. The next groups of land plants to evolve were ferns, which could grow bigger and taller because they could transport water and food.
What trait most likely evolved in ferns that was not present in the earlier groups?
cuticles
seed shells
vascular tissues
photosynthesis

If equal masses of sand and water are heated to the same temperature, which sample will absorb more energy? Base your argument on the definition of heat and what you learned from the experiment.
Answers
This is because it is a solid, and more
of a conductor of heat. Water on the
other hand is not a conducter of heat,
You can observe that even more when
the temperatures are equal.
It depends on the specific heat capacity of the sand and water samples, which is a measure of the amount of energy required to raise the temperature of a substance by one degree Celsius.
What is specific heat?Specific heat is a physical property of a substance that describes the amount of energy required to raise the temperature of a given amount of the substance by one degree Celsius (or one Kelvin).
According to the definition of heat, it is a form of energy that is transferred between two substances due to a difference in temperature.
The amount of heat transferred between two substances is proportional to the temperature difference and the specific heat capacity of the substances.
In general, water has a higher specific heat capacity than sand, which means that it takes more energy to raise the temperature of a given mass of water compared to the same mass of sand.
Therefore, if equal masses of sand and water are heated to the same temperature, the water sample will absorb more energy compared to the sand sample.

What evidence supports the conclusion that all the dinosaurs went extinct about 65 million years ago?
Answers
Answer:
Explanation:
Evidence suggests an asteroid impact was the main culprit. Volcanic eruptions that caused large-scale climate change may also have been involved, together with more gradual changes to Earth's climate that happened over millions of years.
Dinosaurs went extinct 65 million years ago for reasons that are still unknown, but we still have theories. So in conclusion, we know that the impact theory shows that a meteorite or asteroid hit the earth kicking up enough dust to block the sun affecting the food chain. Affecting the dinosaurs. The dinosaur-killing crash threw huge amounts of debris into the air and caused massive tidal waves to wash over parts of the American continents. There is also evidence of substantial fires from that point in history. A new theory says the dinosaurs were killed by a comet fragment that originally came from the solar system's edge. For decades, the prevailing theory about the extinction of the dinosaurs was that an asteroid from the belt between Mars and Jupiter slammed into the planet, causing cataclysmic devastation that wiped out most life on the planet.
Which compares the gases released by fertilizers and gases from landfills?
A. Chemicals from fertilizers can release nitrous oxide, while landfills release methane.
B. Chemicals from fertilizers can release methane, while landfills release nitrous oxide.
C. Chemicals from fertilizers can release carbon dioxide, while landfills release methane.
D. Chemicals from fertilizers can release methane, while landfills release carbon dioxide.
Answers
Answer: a
Explanation: tell me if wrong and sorry
The powerful greenhouse gas nitrous oxide is released into the atmosphere when a large portion of the fertilizer that has been applied runs off into waterways or is broken down by soil bacteria. Thus, option A is correct.
What are the gaseous release by fertilizers?MSW goes through an aerobic (with oxygen) decomposition stage in a landfill when it is initially dumped, during which little methane is produced.
Once anaerobic conditions have been established, which normally takes less than a year, methane-producing bacteria start to break down the waste and produce methane.
However, their creation and usage have a negative impact on the environment since they release nitrous oxide.
Therefore, Chemicals from fertilizers can release nitrous oxide, while landfills release methane.

C. A change in the amount of polar ice will reflect more sunlight toward the Eastern Seaboard.
D. A change in the amount of polar ice will alter how ocean currents move.
Answers
Scientists do believe that winters might be milder on the Eastern Seaboard in the future because a change in the amount of polar ice will alter how ocean currents move. Thus, the correct option for this question is D.
What is Ocean current?Ocean currents may be defined as the gradual and continuous movement of seawater that is significantly generated by a number of forces that are acting upon the water. These forces include winds, gravity, density, the Coriolis effect, etc.
Alterations in the amount and concentration of polar ice will slowly change the movement of ocean currents. This is because the transformation of one state to another leads to differences in their characteristics. For example, when ice is transformed into liquid water, its density and migration of molecules with it increase.
Therefore, a change in the amount of polar ice will alter how ocean currents move is the most prominent reason for scientific belief. Thus, the correct option for this question is D.

fossil energy sources, including oil, coal, and natural gas, are non-renewable resources formed when prehistoric plants and animals died and were gradually buried by layers of rock.
The nation's wind supply is abundant and inexhaustible. Over the past 10 years, U.S. wind power capacity has grown 15% per year, and wind is now the largest renewable power source in the United States. It's sustainable. Wind is actually a form of solar energy.
The sun provides more than enough energy to meet the whole world's energy needs, and unlike fossil fuels, it won't run out anytime soon. As a renewable energy source, the only limitation of solar power is our ability to turn it into electricity in an efficient and cost-effective way.
hydroelectric is a renewable energy source. Hydroelectricity uses the energy of running water, without reducing its quantity, to produce electricity.
