Because the earth is in an angle so the northern hemisphere receives more heat and vice versa
By definition, a chaparral ecosystem is mostly located in the south of the United States wherein it mainly comprises the mountain ranges of Sierra Nevada. In addition to that, biotic characteristics of these chaparrals include having abiotic factos such as wet winters and dry summers that sometimes cause wildfires.
Answer:
Species
Explanation:
Species is the most specific and basic taxonomic level of classification and also the basic unit of biodiversity. Species is defined as group of highly closely related organisms that mate or breed to produce fertile offspring. After species genus is specific, and mostly organisms names are identified by species names and genus names as in binomial nomenclature, all scientific names are derived from genus and species e.g. the scientific name of frog is <em>Rana tigrina, </em>here '<em>Rana</em>' is genus name that is always capitalized and '<em>tigrena</em>' is species name that starts with small letter but both are always written in italics or underlined.
Answer:
<em>(I) Lamarckism or Theory of Inheritance of Acquired characters.</em>
This theory is based on the comparison between the contemporary species of Jean Baptiste de Lamarck's time to fossil records.
<em>(II) Darwinism or Theory of Natural Selection.</em>
Charles Darwin made an extensive study of nature for over 20 years, especially in 1831-1836 when he went on a voyage on the famous ship “H.M.S. Beagle” and explored South America, the Galapagos Islands and other islands.
<em>(III) Mutation theory of De Vries.</em>
The mutation theory of evolution was proposed by a Dutch botanist, Hugo de Vries (1848-1935 A.D.) in 1901 A.D. in his book entitled “Species and Varieties, Their Origin by Mutation”. He worked on evening primrose (Oenothera lamarckiana).
<em>(IV) Neo-Darwinism or Modern concept or Synthetic theory of evolution.</em>
The detailed studies of Lamarckism, Darwinism and Mutation theory of evolution showed that no single theory is fully satisfactory. Neo-Darwinism is a modified version of theory of Natural Selection and is a sort of reconciliation between Darwin’s and de Vries theories.
Answer:
Bacteria
Virus
Parasite
Fungi
Explanation:
A Bacteria is a single-celled biotic pathogen that is infectious. Bacteria are prokaryotes(single celled) and also form part of the disease causing organisms .
A Virus is an abiotic pathogen that is infectious.
A Parasite is a biotic pathogen that lives off its host. It sometimes uses structures such as hooks to obtain nutrient material from its host.
A Fungi is a biotic multi-celled pathogen that causes infections like ringworm.
