Answer:
It results in the synthesis of NAD+
Explanation:
Glycolysis is a metabolic pathway that converts glucose molecules into pyruvic acid -also known as pyruvate-, and a hydrogen ion (H+). Glycolysis is an anaerobic pathway that is independent of the presence of oxygen. This pathway generates energy by the formation of 2 ATP, 2 NADH, and 2 pyruvic acid molecules, these last molecules are used in the citric acid cycle to generate more energy. The pyruvic acid generated by glycolysis enters the mitochondrion to be first converted into acetyl-CoA and subsequently into citrate.

Explanation:
in natural selection, the species that are most likely to survive are pick an answer better at camouflagebetter trainedbetter at avoiding predatorsbetter adaptedj
A general rule of natural selection is that only the fittest survive. This does not necessarily mean that the strongest or the largest will survive.
It means that those that are best adapted to a specific environment will survive, for example, in a snowy environment certain animals will be the fittest, but in a jungle environment, the fittest will be others.
Another important rule is that natural selection selects the fittest not only to survive but to leave offspring and therefore perpetuate the genes suitable for a specific environment.
Therefore, the answer would be D (the most likely to survive are those who better adapt to a specific environment leaving offspring)

Itching and other skin problems are signs that a cat or dog may have flea. Fleas are parasites known for their biting and blood-sucking abilities. When they bite, flea saliva enters the pet’s circulatory system, sometimes causing an allergic response commonly seen as a “hot spot” on the pet’s neck or the base of its tail.
Fleas are tiny parasitic insects that infest the fur of dogs and cats. They feed on blood and cause skin irritation that results in itching. If the problem is severe, it can lead to more significant health issues. Pet owners should watch for signs of fleas and treat their pets promptly to avoid complications. Fleas lay eggs on the skin of dogs and cats, which hatch and develop into larvae.
The larvae feed on the skin, shedding as they mature. Adult fleas emerge from the larvae, biting the host to feed on blood. The process repeats itself, with adult fleas continuing to lay eggs on the skin of the pet.The most common sign of fleas in dogs and cats is itching. Pets will often scratch themselves, bite their skin, or lick excessively to relieve the irritation.
Other signs of fleas include red or inflamed skin, hair loss, and the appearance of small, raised bumps on the skin. These bumps are often referred to as "flea dirt" and are the waste products of the fleas. In severe cases, anemia, an allergic reaction, or the transmission of other parasites or diseases can occur.
Flea infestations can be treated with a variety of products, including topical treatments, shampoos, and collars. It is essential to follow the instructions on the product label and treat the pet and the surrounding environment to eliminate the fleas. Prevention is key to avoiding flea infestations, so pet owners should maintain a regular grooming and flea prevention schedule.

how does similar amount of light transmit through and reflect off the one way mirror
Similar rates of light transmit are reflect through one-way mirror by the use of total internal reflection for example formation of multiple images.
How does light pass through a one-way mirror?Since a one-way mirror is known to often transmits light equally well in both directions, the term "one-way" mirror is known to be somewhat misleading. It only behaves as you would like it to under specific lighting circumstances.
Therefore, The incident light ray is refracted away from the normal as it strikes the mirror surface, and the critical angle is greater than the normal. As a result, the light beam reflects as well as partially transmits or refracts.

The data shows a significant decrease in grizzly bear deaths from 581 in the earlier period to 281 in the later period.
The information about grizzly bear deaths in Alberta from 1976 to 1988 and from 1988 to 2000 affects the prediction made in question 1 by providing additional data points and context.This decrease in grizzly bear deaths suggests a possible declining trend in the population. If the overall trend continues, it is reasonable to assume that the population has decreased further since 2000.
Taking this new information into account, the prediction made in question 1 should be revised. Instead of assuming a stable population or a slight increase, it would be more accurate to predict a decline in the grizzly bear population in Alberta. However, it is important to note that additional factors, such as conservation efforts or changes in habitat, should also be considered to gain a comprehensive understanding of the population dynamics.

The image is an energy pyramid for a particular food chain. The amount of energy received by the macaws will be 5600. Macaws are captured and kept as pets. If the number of macaws decreases because of excess capture, the amount of energy received by the ocelots will be less than 5600
How do we know?in a typical energy pyramid, the amount of energy available decreases as you move up the food chain. This means that organisms higher up in the food chain, such as ocelots, receive less energy compared to organisms lower down, such as macaws.
If the number of macaws decreases due to excess capture, it would likely result in a decrease in the energy available for ocelots, as they rely on macaws as a food source.
This can disrupt the energy flow and potentially impact the population and survival of ocelots.

Complete question:
Some students were asked to contrast photosynthesis and cellular respiration. Which of the following correctly identifies a difference in the two?
1. Cellular respiration stores ATP, and photosynthesis releases ATP.
2. Photosynthesis uses oxygen, while cellular respiration produces carbon dioxide.
3. Photosynthesis uses sunlight, while cellular respiration releases sunlight.
4. Photosynthesis uses carbon dioxide, and cellular respiration produces carbon dioxide.
Answer:
The correct option is 4. Photosynthesis uses carbon dioxide, and cellular respiration produces carbon dioxide.
Explanation:
Photosynthesis and respiration are two complementary processes.
Photosynthesis occurs in chloroplasts, while respiration occurs in mitochondria. The photosynthetic process needs solar radiation to produce organic compounds, while the respiration process needs the organic compounds to obtain chemical energy. Photosynthesis transforms CO₂ into organic compounds, while respiration transforms organic compounds into CO₂.In the process of photosynthesis, it occurs a release of oxygen, which is then used during the respiration process. Both processes are part of the carbon biological cycle.Both processes use electron transport chains to capture energy, which will be used in other cellular reactions. Respiration´s final products are CO₂, ATP, and waterPhotosynthesis´s final products are carbohydrates and oxygen.
