The difference in the motion of the sled from when the people first start pushing to when the sled is halfway down the hill will be described as after starting off much more slowly, it picks up speed significantly by the bottom of the slope.
At the top of the hill, a sled has pushed itself. If we then apply a tiny push, the sled's initial speed will be 0, indicating that the sled's only starting energy is gravitational potential energy. Therefore, assuming there is no friction, the sled's greatest height will be equal to its initial brightness. So the slides will never make up for a bump that is higher than its starting point. The sled's highest point is equal to its initial height because of the rule of conservation of mechanical energy. The sled will never make it up if they restrict it if the friction is seated.

Which of the following processes produces the most ATP? a aerobic respiration b glycolysis c alcoholic fermentation d lactic acid fermentation
Answer:
b) glycolysis
Explanation:
Up to 36 ATP can be produced from one glucose molecule through aerobic reactions. Therefore, option (A) is correct.
What is aerobic respiration?Aerobic respiration supplies energy to fuel all cellular functions. The reactions result in the production of ATP, which can then be put to use to power other life-sustaining processes, such as growth, repair, and maintenance.
The release of energy that was stored in carbohydrates and lipids during photosynthesis and the subsequent availability of that energy to living organisms is the purpose of the series of enzyme-controlled events known as aerobic respiration.
Glycolysis, the Krebs cycle and respiratory electron transport contribute to the production of 36 ATP for every molecule of glucose that is used up during aerobic cell respiration.

James is conducting an experiment to test the effect of insecticides on frogs. He gives one group of frogs 10 cc of the insecticide and 0 cc of the insecticide to the other group of frogs. After 5 days, the effects of the insecticide are collected. what is the independent variable and dependent variable
Answer:
Independent variable: amount of insecticide
Dependent variable: effects of insecticide on frogs
Explanation:
Dependent variable in a research experiment, is the variable that is being studied, tested and measured by the researcher, while the independent variable is the variable that causes the dependent variable to change, when it is varied.
In this case, the amount of insecticides that is varied in quantity, is the independent variable that the researcher manipulates, while the independent variable is the effects caused by these varied amount of insecticide on frogs, which is tested and measured.

All human body cells contain 46 chromosomes. However, sperm cells in men and egg cells in women have only 23 chromosomes. This is due to meiosis. How does meiosis accomplish the reduction in chromosomal number?
Answer:
Two cell divisions after DNA replication
Explanation:
After the DNA is replicated, the cell undergoes two rounds of meiosis to produce 4 cells, each wIth 23 chromosomes. This is how the cell goes from a diploid to a haploid state.

Farmers brought nutria, a type of large rodents, from South America to North America in the 1990s. They wanted to raise the rodents for their fur. Some of these rodents escaped into the wild and became a major pest in the Gulf Coast and Chesapeake Bay regions. Grasses and shrubs in these regions are vital, because they provide food and shelter for many species. They also help in preventing soil erosion. The nutria are eating up all the grasses and shrubs, which affects the food cycles of these regions. The entire ecosystems are being disrupted.
Moreover, nutria pose a direct threat to humans. These rodents are an effective vector for carrying parasites that can cause disease in humans. They also damage property. The burrows created by nutria can damage dams and building foundations as well as cause erosion near streams and lakes.

the answer from pluto/edmentum
Answer:
The apple snail is a native species of Argentina, Bolivia, Brazil, Paraguay, and Uruguay. Southeast Asia legally imported this alien species to use it as a protein source. Later, this species was brought to places like Hawaii as a source of food.
Like most, if not all, invasive species, the apple snail outcompetes native species for resources. This is because it reproduces rapidly (laying hundreds of eggs every few weeks) and lacks predators. As a result, the snails spread rapidly to aquatic biomes and modify the natural balance of aquatic ecosystems.

ATP can convert to ADP during ___________.
Answer:
phosphorylation
Explanation:
ATP usually releases energy by breaking down the weak phosphate cell present. The energy released due to the breaking down of the phosphate cell is then utilized. The ATP is converted to ADP. Whenever a cell feels the necessity for energy it releases a phosphate to gather the energy. It is an automatic and ongoing process. The weak bond between the second and the third phosphate is always targeted for turning ATP to ADP. This is the reason ATP is considered the main energy currency for the cell.
Answer:
phosphorylation

When Alfred Wegener first noticed that the continents fit together like puzzle pieces, this was
Answer:
- the discovery of the Pangaea Theory.
In 1912 Alfred Wegener (1880-1930) proposed that the continents were once compressed into a single protocontinent which he called Pangaea (meaning "all lands"), and over time they have drifted apart into their current distribution.
The east coast of South America and the west coast of Africa seem to fit together like pieces of a jigsaw puzzle, and Wegener discovered their rock layers “fit” just as clearly. South America and Africa were not the only continents with similar geology. Most all of the other continents fit together too.

Why must the bonds of these molecules be broken before anything else happens?
Answer:
Synthesis releases energy because the molecules bond to form a stable configuration and therefore give up energy. The bonded molecules have a lower energy level than free molecules and are held in the new bond.
Explanation:
Chemical reactions make and break the chemical bonds between molecules, resulting in new materials as the products of the chemical reaction. Chemical reactions can occur spontaneously or require an outside trigger such as an input of energy. Breaking chemical bonds absorbs energy, while making new bonds releases energy, with the overall chemical reaction being endothermic or exothermic.
Because molecules must link together to establish a stable structure, they lose energy during synthesis. The newly formed bond holds the bonded molecules, which are at a lower energy level than free molecules.
Why the bonds of molecules are broken?Because molecules must link together to establish a stable structure, they lose energy during synthesis. The newly formed bond holds the bonded molecules, which are at a lower energy level than free molecules.
Chemical reactions create and destroy the chemical bonds that hold molecules together, creating new materials as their end product. Chemical reactions can start on their own or need an outside trigger, like an energy input. Chemical reactions can be endothermic or exothermic in that breaking chemical bonds takes energy while creating new ones releases it.

Identify minerals extracted in Haiti
and describe what is done with
them.
Answer: Haiti is mainly know for their minerals! the main minerals extracted are: cooper, silver, and GOLD. Haiti has many many gold farms, markets, etc. HOWEVER this is a very poor area, as people here live off of only about 2 dollars per day. They could take this wealth and put it towards the people, roads, and construction, as they had an earthquake that killed many many people, and destroyed much. If you mean what they do with gold, they take the gold from farms, and mine it underground. They then sell it for money as this is a poor area as said before!
