Which scenario would most likely result in the extinction of one or more species?
The water temperature of a pond decreases slightly, and the members of the pond populations adapt to the change.
The conditions are abnormally dry for one season in a desert, resulting in the deaths of a few members of a snake population.
A predatory fish is introduced into a lake, resulting in a dramatic decrease in the populations of smaller fish.
A new plant species begins growing in a forest, resulting in a new food resource for many animal populations.
WILL BARK BRANLIY!!!! 25 POINTS!!!
Answer:
C) A predatory fish is introduced into a lake, resulting in a dramatic decrease in the populations of smaller fish.
Explanation:
The other options wouldn't make sense because none of them would cause the extinction of a species. The animals would either adapt or only a few would die. If a new predatory fish were introduced into a lake that had never had it before, lots of the fish would die.

Euglena, Amoeba and paramecium are unicellular organisms. Euglena moves by flagellates, Amoeba by pseudopods and paramecium moves using cilia.
What are unicellular organisms?Unicellular organisms are lower level organisms having only one cell and an undeveloped nucleus. Most of them are aquatic lives and moves using some special organelles.
Amoeba moves by an arm-like structure emerging from its body and contains microtubules within the arms. Euglena is flagellated microorganism moving by flagella.
Paramecium is an aquatic unicellular microorganism having special whip like structure called cilia which moves it in back forth. Ciliary bodies are like oars to move in a direction.
Therefore, amoeba moves by pseudopodium, euglena moves by flagella's and paramecium moves by cilia.

which are characteristics of a eukaryotic cell? A. single cellular, has nucleus.
B. Multicellular, has nucleus.
C. single cellular, has no nucleus.
D. Multicellular, has no nucleus.
Answer:
A eukaryotic cell is much more complex than a prokaryotic cell. Eukaryotic cells usually make up more complex organisms and have organelles such as endoplasmic reticulum, Golgi apparatus, mitochondria, a nucleus, and lysosomes. A prokaryotic cell only has circular chromosomes and is much smaller than a eukaryotic cell. Most single celled organisms are prokaryotes.

Answer:
There are about 50 Orange-bellied Parrots remaining in the wild and a captive breeding population of around 320 individuals. The species is at risk of extinction in the wild in the near term. Current expertise suggests that habitat loss and degradation, particularly in the non-breeding range, has caused the decline.

How did the underwater volcano form?
Answer:
Underwater volcanoes form much like volcanoes on dry land by a process known as subduction.
Explanation:
This occurs as a result of tectonic plates which form the top layer of the Earth's mantle, just below the Earth's crust. They support the weight of the continents and the combined water of the seas.

Explanation:
The diagram on the left shows the layers of Earth's atmosphere and how temperature changes with altitude. The diagram on the right shows the layers of Venus' atmosphere and how temperature changes with altitude. Both diagrams indicate the altitude below which 90% of each atmosphere's mass is located.
According to the diagrams, which of the following statements is true?
A.
90% of the mass of Venus' atmosphere is within 10 km of the surface.
B.
The upper part of Venus' troposphere is about 200°C colder than the upper part of Earth's.
C.
Venus' troposphere is several times thicker than Earth's troposphere.
According to the diagrams. the following statements which is true is the upper part of the Venus' troposphere is about 200°C colder than the upper part of the Earth's atmosphere. Thus, the correct option is B.
What is the relation between troposphere and temperature?As the elevation increases, there is less air above us thus the pressure keeps on decreasing. As the pressure decreases, air molecules spread out further and expand in air, and the temperature of the atmosphere decreases.
Temperature of the atmosphere decreases with the increase in altitude because the troposphere is warmed from below, through the absorption and re-emission of incoming solar radiation by the Earth's surface, rather than it is being warmed from above through the incoming solar radiation.
According to the given diagram, the statement which is true is that the upper part of Venus' troposphere is about 200°C colder than the upper part of Earth's.
Therefore, the correct option is B.

How does the ocean interact with land and air?
Answer:
Explanation:
One way that the world’s ocean affects weather and climate is by playing an important role in keeping our planet warm. The majority of radiation from the sun is absorbed by the ocean, particularly in tropical waters around the equator, where the ocean acts like a massive, heat-retaining solar panel. Land areas also absorb some sunlight, and the atmosphere helps to retain heat that would otherwise quickly radiate into space after sunset.
The ocean doesn't just store solar radiation; it also helps to distribute heat around the globe. When water molecules are heated, they exchange freely with the air in a process called evaporation. Ocean water is constantly evaporating, increasing the temperature and humidity of the surrounding air to form rain and storms that are then carried by trade winds. In fact, almost all rain that falls on land starts off in the ocean. The tropics are particularly rainy because heat absorption, and thus ocean evaporation, is highest in this area.
Outside of Earth’s equatorial areas, weather patterns are driven largely by ocean currents. Currents are movements of ocean water in a continuous flow, created largely by surface winds but also partly by temperature and salinity gradients, Earth’s rotation, and tides. Major current systems typically flow clockwise in the northern hemisphere and counterclockwise in the southern hemisphere, in circular patterns that often trace the coastlines.
Ocean currents act much like a conveyor belt, transporting warm water and precipitation from the equator toward the poles and cold water from the poles back to the tropics. Thus, ocean currents regulate global climate, helping to counteract the uneven distribution of solar radiation reaching Earth’s surface. Without currents in the ocean, regional temperatures would be more extreme—super hot at the equator and frigid toward the poles—and much less of Earth’s land would be habitable.

How does the magma in underwater volcanoes in Hawaii form?
Answer:ike a blowtorch, the heat transforms deep rocks into oozy magma
Explanation:
Answer:
Like a blowtorch, the heat transforms deep rocks into oozy magma. The magma rises upward until it erupts onto the seafloor. When the sizzling lava (which is what magma is called when it erupts) hits the cooler water, it hardens into an underwater volcano, the heat transforms deep rocks into oozy magma
