A is a Comet, B is an asteroid
Explanation:
From its long hazy tail, it appears that the object in figure A is a comet. Comets are a mixture of ice, frozen carbon dioxide, rock, and dust. The bodies shown in figure B appear to be asteroids, which are chunks of rock.
D is the answer cause
A genome is an organism's complete set of DNA including all of its genes. Each genome contains all of the information needed to build and maintain that organism. This is the largest in the given options.
Chromosomes are the threadlike structures located inside the nucleus of animal and plant cells.
The building blocks of nucleic acids are the nucleotides.
A gene is the basic physical and functional unit of heredity. Genes are made up of DNA.
Thus, the correct answer is option (D), 'Genome, chromosome, gene, nucleotide'.
Yes, humans are a keystone species by virtue of their technology<span> as well as the manner in which they influence their natural habitat. If humans were to become extinct, pets, </span>livestocks<span>, and crop plants would also follow. On the other hand, the species that would likely grow in number would be mountain </span>gorillas, whales and weeds. <span> </span>
Answer:
Explanation:
Paleontologists are scientists that study the history/existence of past lives by collecting and examining fossils. They use these fossils to determine the history and age an organism has existed. Fossils are remains of dead organisms (plants and animals) which serve as evidence of past lives that have existed on earth in the past. They could include bone remains or footprint of this animals.
Fossils (from bones) are however mostly incomplete because they decompose before they are "stored naturally" by sediments which covers them. When scientists discover this incomplete fossils, they are compared (if there has been similar fossils discovered before then) and are stored and transferred to the lab for examination. This examination includes anatomical comparison (to determine relatedness with other fossils/organisms), carbon dating (to determine age) and data comparison (which includes location and type of soil and habitat).
