a group of scientists wants to test the effects of decreased oxygen levels in the water on a population of albacore. what result from this experiment would show natural selection in progress?
Fish that can survive the lower oxygen levels undergo natural selection. These fish will reproduce and proliferate.
The water's lower oxygen levels will impact fish respiration. The fish may relocate to a better area with more dissolved oxygen in order to adapt to the change. However, because the fish are still the same genetically and phenotypically, there is no connection to the process of natural selection. Fish that can survive the reduced oxygen levels are selected naturally. These fish will reproduce and multiply in quantity. Fish from the next generation will be tolerant of decreased oxygen levels. This novel phenotypic denotes a modification in the genetic makeup of the fishes.

a model rocket is accelerating at 2m/s square. the force on it is 1N what is the mass of the rocket? with explanation plsssss
The mass of the model rocket accelerating at 2m/s² with a force of 1N in it will be 0.5 kg.
Force (F) is the external component that has the capability to change the state of motion or rest of a body. The formula for force is mass of the body (m) multiplied by its rate of acceleration (a).
F = m.a
Acceleration is the rate of change in the velocity of an object with change in time.
According to the question,
Force = 1N or 1 kg⋅m/s² ( 1 N = 1 kg⋅m/s²)
Acceleration = 2m/s²
The formula can be written as: m = F/a
Therefore, m = 1 kg⋅m/s² / 2 kg⋅m/s²
Hence, the mass of rocket = 0.5 kg.

When some bacteria use lactose as a source of energy, they produce propionic acid and carbon dioxide. What is the name for this process?.
When some bacteria use lactose as a source of energy, they produce propionic acid and carbon dioxide. The name of this process is fermentation.
What is fermentation?
Fermentation is an anaerobic chemical process that breaks down molecules like glucose. More specifically, fermentation is the foaming that happens during the creation of wine and beer, a procedure that has been around for at least 10,000 years.
The word "fermentation" currently refers to the enzyme-catalyzed, energy-producing route in cells that involves the breakdown of substances like glucose under anaerobic conditions. Thus, the processes that result in the synthesis of ATP and pyruvate during the transformation of sugar in muscle, yeast, certain bacteria, and plants are similar.
Therefore fermentation is what happens when bacteria use lactose as a source of energy and produce propionic acid and carbon dioxide.

Which polysaccharide is an important component in the structure of many arthropods and fungi?.
Answer:
Chitin
Explanation:
Which polysaccharide is an important component in the structure of insect and fungal cells?
Chitin is a big, structural polysaccharide made up of chains of modified glucose that serves as a structural protein. Among the invertebrates and fish, chitin is found in the exoskeletons of insects, the cell walls of fungus, and some hard structures in their exoskeletons. Chitin is only second to cellulose in terms of abundance, with cellulose being the first.
Which polysaccharides are important for structural support in animals and plants?
Polysaccharides are mostly used for one of two purposes: energy storage or structural support, depending on their structure. Starch and glycogen are both very compact polymers that are utilized to store energy in the form of carbohydrates. Animal and plant cellulose, as well as chitin, are linear polymers that provide structural support in both plants and animals, respectively.

They would produce endospores.
A stream of water holds thriving bacteria. If drought conditions caused the stream to dry up, they would produce endospores. The correct answer is option D
Why do bacteria produce endospores?
Endospores are external structures produced by bacteria when harsh conditions are present. This survival skill ensures the bacteria survives a harsh condition such as high temperatures.
The bacteria forming an endospore would be able to survive unfavorable environmental conditions such as when the stream dried up.
In summary, when the stream dried up, it exposes the organisms that lives in the stream to heat, and lack of water. Under this condition, most organisms would die, but the endospores produced by the bacteria living in the stream would ensure it survives that condition until water returns to the stream.

How has bumblebees organism evolved?
Bumblebees are believed to have originated from hunting wasps that developed a liking for honey and opted to go vegetarian.
Bumblebees likely evolved on Earth at the same time as flowering plants during the Cretaceous period, between 146 and 74 million years ago, but fossil evidence is scant.
What modifications have bumblebees undergone?Bumble bees are accustomed to cold weather, which is one reason why they are more prevalent there. This indicates that they have certain adaptations—the most notable of which is their thick, fluffy hair—to stay warm in chilly climates. They may also be less able to cool themselves in hot weather due to these adaptations.
About 30–40 million years ago, the first bumblebees broke into this realm of giants. This coincided with a time when the weather was colder, which may have encouraged bees to become bigger and furrier.
Bumblebee looks up to Optimus as a mentor and a father figure. They previously worked together during the conflict on Earth and on Cybertron.

31) prairie dogs once covered the expanses of the great plains. their grazing made the grass more nutritious for the huge herds of bison, and a variety of snakes, raptors, and mammals preyed on the rodents. in fact, the black-footed ferret (now endangered) specialized in prairie dog predation. today, growing housing and agricultural developments have covered many prairie dog towns. which of the following statements about prairie dogs is true? a) their realized niche has expanded. b) they have a mutualistic relationship with bison. c) they are probably a poor candidate for keystone species. d) their fundamental niche is changed. e) their fundamental niche has expanded.
E) Their core target market has grown
Prairie dogs play a significant role in the ecosystems they live in. They have an impact on grasslands both directly and indirectly due to their grazing, burrowing, and role as prey.
How do prairie dogs change with the surroundings?Some of their physical modifications have given them the ability to thrive at what they do. Burrow-digging is made easier for them by their long-nailed toes and short, powerful arms. Despite having tiny legs, prairie dogs can travel short distances at speeds of up to 35 mph in order to flee from predators and reach the safety of their burrows.
The prairie dog is a keystone species because it is essential to the health of the entire ecosystem in which it lives. The reason for this is that prairie dogs are able to make the soil more fertile, improving the conditions for plant growth and benefiting herbivores. They also reproduce quickly and serve as prey for a variety of predators, thus they are in high demand.
