What is the difference between mechanical energy and electrical energy?
Answer:
Kinetic Energy can be defined as the energy possessed by the object by the virtue of its motion. The sum of these two energies is often called Mechanical Energy of the System. Electric Energy is also a form of these 2 energies: Electric potential energy stored in a charged particle in an electric field.

A new dog breed is less likely to cause an allergic reaction in humans. Which statement explains how artificial selection led to the development of this desirable trait?
Different dogs were bred with other animal species such as cats to introduce new nonallergic traits to obtain the new dog breed.
Different dogs were bred with other animal species such as cats to introduce new nonallergic traits to obtain the new dog breed.
Different dog breeds were chosen for nonallergic traits and bred with each other to obtain the new dog breed.
Dogs were trained over generations to not produce and release proteins that cause allergic reactions in humans to obtain the new dog breed.
Dogs were kept outdoors over generations to build up a natural defense against allergens in the environment to obtain the new dog breed.
Answer:it is c
Explanation:cuz it is
Answer:
C
Explanation:
Because they would test the dogs for traits and then selectively breed them

Answer:
Fires often remove alien plants that compete with native species for nutrients and space, and remove undergrowth, which allows sunlight to reach the forest floor, thereby supporting the growth of native species. ... Overall, fire is a catalyst for promoting biological diversity and healthy ecosystems.
Explanation:
What must be true if prokaryotes evolved into eukaryotes by endosymbiosis
Answer:
The ability to absorb other cells gave some prokaryotes a survival advantage.
Explanation:
A researcher recently discovered a new species of bacteria in the body of a tubeworm living near a hydrothermal vent. He compared the DNA of this new bacterial species to the DNA of four other species of bacteria. The DNA sequences came from the same part of the bacterial chromosome of all four species. According to these data, the unknown bacterial species is most closely related to
Answer:
That are more similar to each other.
Explanation:
The unknown bacterial species is most closely related to that bacteria which experience high temperature because both bacteria can live and survive in hot climatic conditions. The new species of bacteria and other four bacteria have some similar features due to similar chromosome but also have some differences due to difference in environmental conditions where they survived so those bacteria that have more similarities are more closely related to each other.

1If you have 52.4 grams of hydrogen and 52.4 grams of helium, which one has a greater mass ? Why ?
Answer:
Hydrogen.
Explanation:
Hydrogen has greater mass and it's bigger than helium because as we move from left to right on the periodic table, atomic size decreases. Hydrogen atom is normally signified than H2 which is bigger than an atom of helium.
Also hydrogen has an atomic radius of 53pm while Helium has an atomic radius of 31 pm. Therefore the mass of helium is smaller than that of hydrogen.
how much will atmospheric carbon change in 10 years
Answer:
Explanation:
Carbon dioxide is a greenhouse gas: a gas that absorbs and radiates heat. Warmed by sunlight, Earth’s land and ocean surfaces continuously radiate thermal infrared energy (heat). Unlike oxygen or nitrogen (which make up most of our atmosphere), greenhouse gases absorb that heat and release it gradually over time, like bricks in a fireplace after the fire goes out. Without this natural greenhouse effect, Earth’s average annual temperature would be below freezing instead of close to 60°F. But increases in greenhouse gases have tipped the Earth's energy budget out of balance, trapping additional heat and raising Earth's average temperature.
Carbon dioxide is the most important of Earth’s long-lived greenhouse gases. It absorbs less heat per molecule than the greenhouse gases methane or nitrous oxide, but it’s more abundant and it stays in the atmosphere much longer. And while carbon dioxide is less abundant and less powerful than water vapor on a molecule per molecule basis, it absorbs wavelengths of thermal energy that water vapor does not, which means it adds to the greenhouse effect in a unique way. Increases in atmospheric carbon dioxide are responsible for about two-thirds of the total energy imbalance that is causing Earth's temperature to rise.
What are two things that can make the pressure of a gas rise? (what are two variables you can change to increase the pressure) *

When a squirrel hears a strange noise that might indicate the presence of a predator, fight-or-flight hormones are released into its system. The hormones help prepare the squirrel's body to do strenuous physical activities, like quickly climbing up a tree, more efficiently. Which statement describes how two organ systems work together to help a squirrel respond to a possible external threat?
Answer:
The flight-or-flight hormones are released by the endocrine system in response to environmental changes detected by the nervous system.

Sophie visited Carlsbad Caverns with her family during her summer vacation, and she was amazed at the cave’s formations. She learned that the cave was formed from minerals.
Rearrange the phrases describing one of the ways minerals form into the correct order. Place the earliest stage of mineral formation at the top. Place the final stage at the bottom. (Write 1 2 3 or 4 in order)
1. a solution forms from a liquid and dissolved substances
2. a warm solution flows through a crack in the rocks there
3. elements and compounds leave as the solution cools
4. elements and compounds crystallize
BASICALLY SAY WHICH STEPS GO FIRST IN MINERAL FORMATIONS! PLESSS
Answer:
The ways through which the minerals form include the following order:
2. a warm solution flows through a crack in the rocks there
1. a solution forms from a liquid and dissolved substances
3. elements and compounds leave as the solution cools
4. elements and compounds crystallize
Explanation:
From the explanations above, it could be seen that a warm solution (most probably water) flows through the cracks in the rocks leading to dissolution of substances to form liquid. When the liquid cools, the elements leaves and crystallize as compounds.
