Romans
Explanation:
In ancient times, baths heated by hot springs were used by the Greeks and Romans, and examples of geothermal space heating date at least as far back as the Roman city of Pompeii during the 1st century ce.
Answer: A warm front forms when a warm air mass pushes into a cooler air mass, also shown in the image. Warm fronts often bring stormy weather as the warm air mass at the surface rises above the cool air mass, making clouds and storms.
Answer:
The correct answer is - option A.
Explanation:
Elephant populations are currently declining lapidary. Human influence is the main and major reason that leads to such a population decline of the elephants. The habitat loss, environmental change, and killing for human safety are the few reasons that affect the population of the elephant, but the major and most responsible cause of the killing and decrease in the elephant population is killing for the ivory of elephants,
Elephant ivory is very expensive and use for making jewelry, artifacts and many more items even illegal medicines are made by ivory.
Thus, the correct answer is option - A.
Answer:
D. Specialist Species
<h2>
What is the advantage for species to be specialists, and how can they survive in the presence of opportunistic/generalist species?</h2>
In the setting of specialized habitats or unique situations, specialized species exist. When those conditions and surroundings change, they must adapt or go extinct, thus they must survive while they still exist.
When compared to generalists, they have the benefit of efficiency, which increases the likelihood of survival and, hence, reproduction within certain settings or situations. The generalists, on the other hand, have the benefit of being able to survive in a larger variety of circumstances and have a higher probability of doing so.
Cactuses, which are plants adapted to dry environments, are an example of specialization. More generalist plant species would typically outcompete cacti in most habitats on Earth, but very few of such species could endure the harsh conditions of a desert.
Extreme environmental conditions, competition for limited resources, and "evolutionary arms races" are some of the pressures that cause specialization. Cheetahs sprint quickly both because their prey moves quickly and because quicker cheetahs will be more effective hunters and more likely to procreate. The advantage of specialization is clear when seen from the standpoint of catching the next meal on a daily basis.
My key argument is that specialization's benefits must always be viewed in the context of the environment that generated the selective pressure that resulted in specialization. Although experts are specialists because they must be, their specializations put them in danger.
