answer is 1.75a for the question
The comet will die or will recover after it has made several trips around the Sun. the tail of the comet always point away from the sun because the sun’s ray heat up and the solar winds push on the comet and then make the tail.
The heat from the Sun vaporizes most of the frozen ice in the comet. The remaining small particles spread out in the orbit of the comet.
Plants utilize carbon dioxide in a method identified as photosynthesis. During photosynthesis, plants yield off oxygen as a decay product. Carbon dioxide passes from the atmosphere into the needles of plants by tiny holes in the plant's leaves.
Both Oxygen cycle and carbon cycle acts independently but are subordinate on each other because the carbon cycle provides off oxygen for the oxygen cycle to use, and in return, the oxygen cycle releases carbon dioxide (CO2) which goes back into the carbon cycle. Plants are the principal vehicle by which the oxygen and carbon cycles are correlated.

B) All invertebrates are chordates; vertebrates are a group that is separate from both invertebrates and chordates.
C) All invertebrates are chordates; vertebrates are a group that is separate from both invertebrates and chordates.
D) Chordates are the largest group, and it is subdivided into two groups: vertebrates and invertebrates.
Answer:
The most appropriate answer would be option A.
The chordates refer to the organisms which belong to the phylum Chordata. They possess anatomical features like notochord, pharyngeal slits, dorsal nerve cord, post-anel tail, and endostyle during some period of their life cycle. They include classes amphibians, fish, reptiles, birds, and mammals. These organisms are believed to share a common ancestor.
In contrast, invertebrates refer to the organisms which lack a vertebral column. They include all the organisms other than vertebrates. For example, they include arthropods, mollusks, annelids, and cnidarians.
