First is the Nebula, a cloud of gas and dust in space where stars are born.
Second is a Star, Luminous globe of gas producing its own heat and light through nuclear reactions.
Third is Red Giant, a large bright star with cool surface, it is formed during the later stage of evolution of a star like our sun.
Fourth is the Red Dwarf, which is very cool, faint and small star.
Fifth is White Dwarf, this is a very small and the last stage in the life cycle of a star.
Sixth is the Supernova, the explosive death of a star
Lastly is the Blackhole, where it is believe to form from a massive stars at the end of their times
Answer:
Carbon dioxide and other pollutants are released into the air.
Explanation:
Answer:
The fossil record helps paleontologists, archaeologists, and geologists place important events and species in the appropriate geologic era.
Explanation:
It is based on the Law of Superposition which states that in undisturbed rock sequences the bottom layers are older than the top layers.
Answer:
A change in pH will cause many cellular processes to be disrupted because they affect the biomolecules (protein and nucleic acid) responsible for these processes.
Explanation:
pH refers to the degree of acidity or alkalinity. In a cell, the structures and processes that occur in them are impossible without the biomolecules, which are carbohydrate, protein, lipids and protein.
However, unfavorable conditions like a change in pH can cause the structure of some of these biomolecules to be affected. Proteins are made up of amino acids, which gives them their shape that is peculiar to their functioning. Also, nucleic acids such as DNA are composed of nucleotides responsible for their functioning.
A change in pH will cause the bonds of the protein to be disrupted, hence altering its shape and ultimately its functioning. Likewise, the hydrogen bonds in the DNA will be broken in the presence of a high pH causing the DNA to be dysfunctional.
When these biomolecules are affected, the vital functions that they perform in a cell, which is key to the cell's survival are disrupted) are likewise affected. Therefore, the cell is affected negatively.
Cats can bite you if they're playing or just want alone time to them selfs. Plus if they think you are going to do harm to them.
Hope this helps! :D
