Two ATP molecules are required to start glycolysis (from glucose), and 4 are generated by substrate-level phosphorylation. An additional 2 NADH molecules are generated, which can be used to generate another 4–6 ATP molecules through the electron transport chain in the mitochondria.
By leaving crop roots in the ground and stalks on the surface, no-till plowing helps prevent ____________________.
*edit* i now found the answer :) and if you are wondering what it is it soil erosion
i know its says biology but its just regular science on edge 2020
Answer:
Soil erosion.
Explanation:
No-till plowing can be defined as a farming method or technique which typically involves planting crops (seedlings) without tilling the soil rather the farmer would only open a narrow or very shallow trench of sufficient depth and width to cover up the seedlings. Thus, the no-till plowing makes crop residues to be left on the soil and by extension preventing soil erosion through the absorption of water by the crop residues.
Hence, by leaving crop roots in the ground and stalks on the surface, no-till plowing helps prevent soil erosion.
Additionally, the water retention ability of no-till plowing is usually a boon to farmers because it slows down evaporation and serves as a good protection for drought-stricken environments.

Where do the calories in your food come from?
Answer: Calories are the amount of energy released when your body breaks down (digests and absorbs) food.
Explanation:
The more calories a food has, the more energy it can provide to your body. When you eat more calories than you need, your body stores the extra calories as body fat. Even a fat-free food can have a lot of calories

Answer:
ACDFHope it helps youThe systems affected by cystic fibrosis are the respiratory, gastrointestinal, reproductive, and integumentary.
Cystic fibrosis is a condition that damages organs in the gastrointestinal system or digestive system and the respiratory system. It can lead to damages in:
The lungs (respiratory system)The pancreas (gastrointestinal system)This condition is caused by the accumulation of mucus on organs due to a defective gene. This accumulation leads to negative effects in these systems but also in other systems such as:
Frequent respiratory infection (respiratory system)Damage to the airways (respiratory system)Digestive problems such as diarrhea or constipation (digestive system)Infertility (Reproductive system)Yellowing of the skin (integumentary system)Thus, the systems affected are the respiratory, gastrointestinal, reproductive, and integumentary; while others such as the lymphatic or neurological are not affected.

A Mismatch occurs when:
A. organisms that were well adapted to one environment cannot evolve rapidly enough to adapt to new circumstances.
B. when an organism is well adapted to its environment
C. when an organism inherits a mutation that decreases its reproductive success
D. when a mutation increases the reproductive success of an organism
Answer:
A
Explanation:
A mismatch occurs when organisms that were well adapted to one environment cannot evolve rapidly enough to adapt to new changes in the environment. Hence, a trait that once confers an adaptive advantage becomes inimical due to the changes in the environment.
In order words, a mismatch occurs when a once adaptive trait becomes maladaptive or no longer confers an adaptive advantage to organisms due to a change in the environment but still persists in organisms.
For example, an organism with a body adapted to aquatic habitat suddenly finds itself in a terrestrial habitat due to climate change. The body that use to be adaptive to the environment would suddenly become maladaptive to the new environment.
The correct option is, therefore, A.

Answer:
Please find the description of the steps involved in DNA replication below. The terms listed in the question are written in BOLD.
Explanation:
DNA replication is the process by which DNA molecule is duplicated in the genome to produce two identical copies. DNA replication, which must occur prior to any cell division, involves the following steps:
- An enzyme called DNA HELICASE unwinds the double strand of DNA into a Y-shaped replication fork.
- Another enzyme called DNA POLYMERASE attaches to the single strand of DNA to add nucleotides to the growing DNA molecule.
- An enzyme called DNA PRIMASE adds a short nucleotide sequence called PRIMER, which serves as foundation for DNA polymerase to act upon.
- The DNA polymerase adds nucleotides based on complementary base pairing rule i.e. A-T, G-C.

1. In your own words, what does it mean for a cell to be
specialized ?
Answer:
For a cell to be specialized it means that, even though the cells are similar, they differ in shape, size, function, and have a different role in our body. Every cell adapts to the function it has in the body.
Explanation:
Differentiation refers to the serial steps that a cell goes through to become mature. As the cell develops, it begins to show its own purpose and role in the human body, a process known as differentiation.

he Axolotl, or the Ambystoma mexicanum, is located in the class amphibia and in the family of Ambystomatidae. They are a critically endangered species that resides in Mexico. More specifically, the walking fish is native only to Lake Xochimilco and Lake Chalco in central Mexico. These unique fish have many attributes that makes it different from other amphibians and fish found in lakes.
Axolotls are 9 inch "walking fish" that have the amazing ability to regenerate limbs. They can regenerate any lost limb, including their head. This salamander has a soft bodies with small "horns" sprouting from the sides of their head. These horns are actually gills, meaning that instead of having their gills located inside of their pharynx the frills are set on the sides of their head.
The spots commonly found on an axolotl are not unusual, it's part of an extremely advanced system called the lateral line system. This system consists of electroreceptive ampullary organs and mechanoreceptive neuromasts organized into lines across the creature's body. This system is connected to the nervous system, and it allows the axolotl to sense movement and vibrations in the water.

Predict what may happen to the population of pepper moths if they were relocated to a lush, green rainforest ecosystem. How would this impact natural selection and their struggle to survive
Answer:
The correct answer is - The population would decrease.
Explanation:
natural selection is a change of an organism that helps in surviving in an environment change that is unfavorable to it. If a population of pepper moths is relocated a lush, green rainforest ecosystem, it the environment could kill off the peppered moths due to their evolutionary characteristics will make them stand out to predators which decreases their population or kill them due to their diet.
Answer:
The Peppered Moth Population Will Decrease or be Completely Wiped Out.
Explanation:
The change would almost inevitably result in the extinction of peppered moths. They would become extinct, whether they were light or dark in color. Because of their color, they would be unable to blend in with their new lush environment. They would also suffer because their diets are different and contain certain animals than those available in the lush forest.
