Answer:
population I stars.
Explanation:
A star is a giant astronomical or celestial object that is comprised of a luminous sphere of plasma, binded together by its own gravitational force.
It is typically made up of two (2) main hot gas, Hydrogen (H) and Helium (He).
The luminosity of a star can be defined as the total amount of light radiated by the star per second and it is measured in watts (w). Also, the apparent brightness of a star is a measure of the rate at which radiated energy from a star reaches an observer on Earth per square meter per second. The apparent brightness of a star is typically measured in watts per square meter.
Some of the examples of stars are; Canopus, Sun (closest to the Earth), Betelgeus, Antares, Vega etc.
New stars that are found in the spiral arms and formed from recycled dead star material are known as population I stars. Also, it comprises of association and clusters formed a million or billion years ago in the spiral arms of Milky Way galaxy.
A galaxy can be defined as a collection or group of many billions of stars and other planetary body which are existing independently.
Hello there
So Ecosystem is a natural process with natural resources and abiotic factors such as sunlight, soil, water and all nonliving things
Components of the ecosystem are the abotic factors that biotic factors which are living things.
Thank you
I look forward to your success Sara
The correct answer is - D: Arthropods.
The arthropods (Arthropoda) are a very large phylum, having almost two million species described so far, and there might be even up to 15 times more than that. The arthropods are one of the oldest organisms that still exist. Their most recognizable characteristics are the exoskeleton, fragmented body, and jointed appendages. They only have an other shell, and do not posses internal skeleton, thus making them hard on the outside, and squishy on the inside. The body is fragmented, the number of fragments is differing from family to family, and that is in order for them to have greater mobility. Another characteristic that enables them greater mobility and flexibility are the jointed appendages. They were also the first more complex organisms that got out on the land, and dominated it for quite some time. Unfortunately for them, they do not have the ability to develop their brains on a higher level, thus they were easily outcompeted by the newly emerging groups of animals and fell into their shades.
