Answer:fungi
Explanation:fungi are heterotrophic plants. They are organisms that lack chlorophyll,true roots,stems and leaves .as a result they cannot produce their own food .they depend on dead and decaying matter for their source of energy, thus they are saprophytes.Fungi may be Unicellular or multicellular. They consist of harlike filaments of hyphae which fuses together and forms a mass of mycellium. Common example of fungi we see around us are mushrooms. Fungi feed by secreting digestive enzymes into their substrate and they absorb the nutrients that are broken down by the enzymes. Fungi are important because they help to rid the environment of dead matter by decomposing them. Matured fungi reproduce asexually by the means of spores
Answer:
D. Competitive
Explanation:
Animals seem to get aggressive during interaction with other animals.
It triggered tsunamis and landslides
Cells because most living things like plant life and humans are made up of cells and animals are made up of cells too!
Answer: Polyploidy
Explanation:
Polyploidy is defined as the phenomenon by which cells, tissues or organisms with three or more complete sets of chromosomes originate. Such cells, tissues or organisms are called polyploids.
If the genomes of a polyploid species come from the same ancestral species, it is said to be autopolyploid or autoploid. And if they come from two different ancestral species, it is said to be allopolyploid or alloploid. <u>Depending on the number of complete chromosome sets that the species has it is called triploid (3X), tetraploid (4X), pentaploid (5X), hexaploid (6X) and so on, where X is the monoploid number, and not to be confused with the haploid number.
</u>
Redundant genetic elements of polyploid organisms can be transformed into single copies by sub-functionalization, neofunctionalization mechanisms or by the appearance of certain mutations.
<u>Two populations are sympatric when they exist in the same area and thus frequently encounter one another. </u>In general, different species cannot interbreed and produce healthy and fertile offspring due to barriers known as reproductive isolation mechanisms. Polyploidy speciation is common in plants but rare in animals. So, animal species are much less tolerant of changes in ploidy. For example, human embryos that are triploid or tetraploid are not viable, cannot survive.
