Answer:
A. A keystone species
Explanation:
The prairies dog is an animal that might not seem as the most important in its ecosystem because it is a small mammal, which doesn't seem to have any great effect on things. In reality, it is the total opposite of it, as the prairie dog is a keystone species in its ecosystem. Its activity results in movement of the water, fertilizing of the soil, making the soil more porous, contribute to the growth of the new vegetation, thus in a way the prairie dog is the key figure in its ecosystem. The species that have such important roles, or rather key roles in the supporting of the ecosystem are called keystone species.
How long can dinosaurs bang for?
Probably like 2 hours or so
Determining the exact duration of dinosaur mating is challenging due to limited direct evidence. Analogies with modern relatives suggest varied behaviors, emphasizing the importance of species-specific factors in dinosaur reproduction.
Determining the mating duration of dinosaurs is a challenging task as it involves interpreting behaviors from fossilized evidence. Fossils provide insights into dinosaur anatomy, but behaviors, including mating rituals, are more challenging to discern. Researchers rely on indirect evidence such as trackways, nesting sites, and bone structures.
The duration of dinosaur mating, or "dinosaur romance," is speculative due to limited direct evidence. Analogies with modern-day reptiles and birds, the closest living relatives of dinosaurs, provide some context. These animals exhibit a wide range of mating behaviors, from brief copulation to more extended courtship rituals.
Factors influencing mating duration in dinosaurs would likely include species-specific behaviors, environmental conditions, and reproductive strategies. Some dinosaurs may have engaged in elaborate courtship displays, while others may have had more straightforward mating behaviors.
In conclusion, the specific duration of dinosaur mating remains uncertain due to the limitations of interpreting behaviors from the fossil record. While modern analogs offer some insights, each dinosaur species likely had unique reproductive strategies that were influenced by their environment and evolutionary adaptations.

What happens next after an mRNA strand separates from a DNA molecule?
Answer: DNA is essentially a storage molecule. It contains all of the instructions a cell needs to sustain itself. These instructions are found within genes, which are sections of DNA made up of specific sequences of nucleotides. In order to be implemented, the instructions contained within genes must be expressed, or copied into a form that can be used by cells to produce the proteins needed to support life.

How does a closed lake differ from an open lake?
A. A closed lake has no outlet stream. B. A closed lake has no inlet stream. C. A closed lake contains fresh water. D. A closed lake contains standing water.
Answer.
A I belive
Explanation:
All lakes are either open or closed. If water leaves a lake by a river or other outlet, it is said to be open.
Answer:
Option A, A closed lake has no outlet stream
Explanation:
An open lake is formed at a place where the water is poured in by inlet stream. Open lake also has outlet stream for removal of water. while in a closed lake , water only leaves by the process of evaporation. The water in a closed lake gets salty as it remains standing and when it evaporates it leaves behind salt and other dissolved constituents thereby remaining water salty.
hence, Option A is correct
Which finding would have disproved Virchow’s hypothesis?
Animalcules are not organisms.
Animals are made of non–cell-based matter.
Plants are made of non–cell-based matter.
Cells can generate from nonliving matter.
Answer:
The correct answer will be option-Cells can generate from nonliving matter.
Explanation:
Rudolf Virchow is known for modifying the cell theory proposed by the Schleiden and Schwann in 1839. He added to the existed theory and suggested that all living cell come from the pre-existed cells.
But this hypothesis was disproved after the Miller and Urey performed an experiment in 1953 and demonstrated that cells were originated from the non-living matter present in the atmosphere during primordial time.
This fact disproved the hypothesis of Virchow ans thus is the correct answer.

Explanation:
describe one way energy from sunlight moves through a food chain in this food web. identify producers and consumers in the food chain.
Answer:
Energy is absorbed by plants in the form of sunlight and grow. These plants are eaten by smaller consumers (such as the grasshopper) and thus the energy moves up the food chain as the grasshopper is eaten by another and so on.
why does water of salt gets salty?
Answer:
Salt in the ocean comes from rocks on land. The rain that falls on the land contains some dissolved carbon dioxide from the surrounding air. This causes the rainwater to be slightly acidic due to carbonic acid (which forms from carbon dioxide and water).

What's the greenhouse effect?
A. The release of extra moisture from water vapor
B. Human-caused global warming
C. The regulation of atmospheric and surface temperatures
D. The trapping of warm air in cities
Answer:c
Explanation:
Final answer:
The greenhouse effect is a natural phenomenon where greenhouse gases in the Earth's atmosphere trap heat, maintaining the planet's temperature at a level suitable for life. Human activities have increased the concentration of these gases, leading to an enhanced effect and contributing to global warming and climate change.
Explanation:
Understanding the Greenhouse Effect
The greenhouse effect is a natural process that warms the Earth's surface. When the sun's energy reaches the Earth, some of it is reflected to space and the rest is absorbed and re-radiated as heat. Greenhouse gases in the atmosphere, such as carbon dioxide, methane, and water vapor, trap this heat, effectively insulating the planet. This process helps to maintain the temperature of our planet at a level suitable for life.
Option D is the correct definition: Greenhouse gases in the lower atmosphere trap heat from outgoing solar radiation causing the atmosphere to warm. However, due to human activities like burning fossil fuels and deforestation, the concentration of these gases in the atmosphere is increasing, leading to an enhanced greenhouse effect. This results in higher temperatures on Earth, a trend commonly referred to as global warming, which is a major component of climate change.
Society is concerned about the impact of human activities on the greenhouse gas effect because these activities are significantly strengthening the effect, trapping more heat, and contributing to global climate changes such as more extreme weather events and rising sea levels.

Which of these processes as a cooling affect on earth? (APEX)
Answer:
The answer is A. Evaporation of water due to warmer temperature causes low thick clouds.
Explanation:
Evaporation is the process in which liquid is changed into gas due to increases temperature or pressure. It is an important part of water recycling in nature. water from sea, rivers and streams evaporate and form clouds which brings water back to earth by raining. Evaporation also causes cooling effect as during evaporation heat is absorbed from the environment. On the other hand the cloud formation and rain also induce cooling by bringing down the temperature.

Over millions of years of time, an island's vegetation shifts. The seed producing plants that
dominated the early origins of the island die out in favor of new species of plants that do
not produce seeds but provide a good habitat for insects. How is this change likely to
affect a species of birds that uses seeds as its primary source of lood and insects as a
secondary food source
A.The species will maintain its heritable traits while learning to make insects their
primary food source,
B.The species will decline and become endangered because its adaptations have
reduced utility
C.The species will split into two one adapted to eating seeds and a second
adapted to eating insects
D.over time a shift in trolts will be olvserved as the species adapts to an insect diet.
over time a shift in trolts will be olvserved as the species adapts to an insect diet
Final answer:
The species of birds that relied on seeds may decline due to the reduced utility of their adaptations, but if adaptable, trait shifts will occur towards an insect diet, potentially echoing Darwin's finches' adaptive radiation on the Galapagos Islands.
Explanation:
When an island's vegetation shifts and the seed-producing plants that previously dominated are replaced by non-seed-producing plants favorable to insects, the species of birds that primarily rely on seeds for food are likely to be affected in a specific way. Over time, if the birds cannot adapt to the available food sources, they may decline and become endangered due to the reduced utility of their seed-eating adaptations. However, if they have the flexibility to change their diet and learn to make insects their primary food source, then over time a shift in traits will be observed as the species adapts to the new food source through natural selection, potentially leading to an evolutionarily significant change in beak morphology or feeding behavior.
