insulin
insulin would be your answer.
b. chemical changes and flow of water
c. physical changes and flow of energy
d. physical changes and flow of water
Answer:
a. chemical changes and flow of energy
Explanation:
Energy flow from one organisms of one tropic level to other, matter cycling and transformation of energy are the functions that sustain the ecosystem. Transformation of solar energy into chemical energy by plants serves as energy source for all heterotrophic living beings in the system. The heterotrophic organisms digest the ingested food (chemical change) to release energy to support their life processes. The energy stored at one tropic level is carried to next tropic level via food chain and food webs and represents the interaction between living components of ecosystem.
B. natural selection.
C. an intrinsic factor.
D. a density-dependent factor.
Answer: Option A (Density-independent factor)
Explanation:
Density-independent factor is a population regulation factor that affect or influence the size of a population without considering the population density. Climate and weather are the main density-independent factors in nature.
Their effects increment is directly proportional to the increase in population size. These factors are environmental agents that checkmate the size of a population without putting the reproductive and behavioral patterns of the organisms into consideration.
Moons like ours are commonplace among the planets and are drawn into orbit by strong gravitation on smaller bodies.
Identical forms of elements on both the Moon and Earth lead scientists to believe that Earth and Moon were formed.
That Earth collided with a Mars-sized body forming the Moon.
The Moon was originally a dwarf planet captured by the Earth's gravitational pull billions of years in the past.
Answer:
C
Explanation:
The most accepted theory on the Moon's origins, the Giant Impact Hypothesis, proposes that a Mars-sized body known as Theia collided with Earth approximately 4.5 billion years ago. This collision ejected material into Earth's orbit, which then formed the Moon.
The most recent and widely accepted theory about the origins of the Moon, known as the Giant Impact Hypothesis, suggests that approximately 4.5 billion years ago, a protoplanet roughly the size of Mars, known as Theia, collided with the nascent Earth. This violent collision resulted in a massive amount of matter ejecting into the Earth's orbit, eventually coalescing and forming what we now know as the Moon. This theory is supported by several pieces of evidence, such as the similar composition of certain isotopes on both the Earth and Moon and the Moon's low density compared to Earth, which suggests it came from the Earth's outer crust.
