The type of population growth that most natural populations follow is
Answer:
The type of population growth that most natural populations follow is Exponential growth.
hope it helps!
Natural populations often follow logistic growth, which includes an initial rapid growth phase followed by a slowdown as carrying capacity is approached. The growth pattern forms an S-shaped curve, commonly seen in species such as the snowshoe hare.
Explanation:Most natural populations follow logistic growth. Unlike exponential growth that continues indefinitely, logistic growth takes into account environmental resources and carries capacity. In a logistic growth model, the population increases rapidly at first, but as it nears its carrying capacity - the maximum population size that an environment can support - the rate of growth slows down and eventually stabilizes.
A classic example of a species that follows logistic growth is the snowshoe hare. Initially, the population will grow rapidly, until resources such as food start to become scarce. As a result, the population's growth rate will slow down and eventually stabilize, demonstrating an S-shaped curve indicative of logistic growth.

Which of the following is a characteristic of multicellular organisms?
They can possess tissues and organs.
All of their functions are performed by a single cell.
They are usually microscopic.
Their cells perform varied functions.
Final answer:
The correct option is: They can possess tissues and organs. Multicellular organisms are characterized by having cells that can form tissues and organs, where cells have specialized functions and contribute to the organism's complexity.
Explanation:
One characteristic of multicellular organisms is that they can possess tissues and organs. Multicellular organisms, which are composed of eukaryotic cells, show a complex level of organization. Similar cells form tissues, groups of tissues comprise organs, and these organs join together to establish organ systems. Such an organization is not seen in unicellular organisms, where all functions are performed by a single cell. Multicellular organisms have cells that perform varied functions and often display division of labor. This division allows different cell types to perform specialized roles, contributing to the organism's overall function and survival.

What is Glacier?
A glacier is a sizable, enduring mass of crystalline ice, snow, rock, silt, and frequently liquid water that forms on land and slides down a slope due to gravity and its own weight.
Average annual temperatures are near freezing, and large snow accumulations result from winter precipitation.
Temperatures during the rest of the year prevent the snow accumulation from being completely lost. The snow eventually becomes a significant enough amount after several decades of continuous accumulation for the process of turning snow into glacier ice to start.
Therefore, A glacier recedes and exposes bare rock Lichen will colonize the bare rock.

stays the same
The amount of water on Earth stay the same.
Water is a substance essential to life and includes rain, groundwater, lakes, ocean etc.
The Water cycle is a cycle which describes the overall movement of water from above the earth to the below the surface of the Earth.Water cycle includes four steps:
Evaporation/Transpiration: The is when water goes into air because of the heat caused by sunCondensation: This is when water vapor caused by sun forms the cloud. Precipitation: This is when the cloud is too heavy for the air to carry and then falls back to the earth. Storage/Collection: This is when the water which falls back is stored or collected such as lakes, groundwater, rivers etcIn conclusion, the cycle of water moves from the fourth step to the first step and continues like that infinitely, thus, the amount of water on Earth stay the same

Convection currents flow due to variations in the temperature and salinity in seawater, which both influence its density. Variations in density in different regions of the ocean will cause water to flow from less dense areas to more dense areas as water heats up and becomes less saline, producing a horizontal convection current. Vertical convection currents can arise as cooler, more saline water sinks, causing warmer, less saline water to rise.
