Which of the following is part of a clade believed to have died out, leaving no descendants?
galina1969 [7]

Answer:

Paranthropus robustus

Explanation:

2.5 million years ago some autralopithecines were identified by dating fossils from South Africa, meaning they lived a good period of time. Of these, Australopithecus africanus is well known and is a little closer to our species. Other fossils found in excavations in both southern Africa and eastern Africa have been found to be of more recent specimens 2.5 to 2 million years ago. These specimens were classified as Paranthropus robustus and Paranthropus boisei. These australopithecine species became extinct and left no current descendants.

andre [41]

Explanation:

Mutations increase variation within a population.

During the process of cell division, spontaneous changes within the genome can arise. These mutations are errors occur when copies of the DNA within the cell are made; mutations may range from small changes called single nucleotide polymorphisms, to large scale deletions, and additions which span multiple genes. There are two types:

  • somatic: these only occur within certain cells, and arise from environmental factors such as UV light
  • hereditary: occur within germ cells of the parent and later the fertilized egg which forms a zygote; these are present within all cells of the new organism.

Further Explanation:

During reproduction other events, such as crossing over during mitosis and meiosis, mutations lead to increases in genetic variation. This variation refers to the genetic characteristics present within a species. Mutations may be either beneficial or deleterious; they are maintained within cells, as they form new traits called alleles. Beneficial mutations may confer traits that increase the fitness of a species, along with ensuring survival by conferring a protective advantage- these phenotypic differences between organisms are called adaptations.

Sequences of DNA make up genes which can have different forms called alleles. DNA, which makes up the genotype, is transcribed into mRNA and later translated into amino acids which are linked together by rRNA to form proteins which make up the phenotype of an organism.Mutations in DNA sequences affect the corresponding mRNA and thus the protein encoded.

Why do farmers in South America get abundant crops during El Niño?
puteri [66]

Answer:

Hundreds of years ago, South American fishermen observed that every year around December or Christmas, coastal waters of the Pacific became warmer as a current flowed from north to south. This change often meant a smaller fish catch but more rainfall inland that translated to more abundant crop harvest .
