The answer is; YES
All organisms share one common ancestor in the beginning of life. Different species have branched at different times from common ancestors hence he evolutionary tree looks like tree called a cladogram. The nodes represent the common ancestry while branches depict divergence. Therefore even fruit flies and the fruit bats even though they do not belong to the same species shared a common ancestor at one time in history.
Answer:
The correct answer is "#2 and #3 only"
Explanation:
A and a are alleles, and R and r are alleles. Alleles of a gene are found at the same locus on homologous chromosomes. Every pair of the alleles depicts the genotype of a particular gene. Homozygous genotype occurs when two similar alleles at same locus and heterozygous in case of two nonidentical alleles. Due to the alleles there occurs a change in the appearance. An alleles create differences in gene.
Answer:
D
Explanation:
Mitochondria in eukaryotes are believed to have evolved from a symbiotic relationship between protists and prokaryotes. It is proposed that maybe it evolved from protists engulfing prokaryotes as ‘food’. The evidence is due to the fact that mitochondria have their DNA that encodes for about 13 proteins used within the organelle. MtDNA is circular in shape which is very similar to the structure of prokaryotic DNA.
Answer: True
Explanation:
Earth's south pole and the magnetic south are not the sole cause but an important element to why Earth is a magnet. "The south magnetic pole is the point on Earth's Southern Hemisphere where the geomagnetic field lines are directed vertically upwards. The Geomagnetic South Pole, a related point, is the south pole of an ideal dipole model of the Earth's magnetic field that most closely fits the Earth's actual magnetic field."
Answer:
false
Explanation:
Phytoplankton are from the water and not found on land.
