Explanation:
Correct answer: A). The current hypothesis of the evolutionary relationships between organisms
The tree of life is a metaphor that expresses the idea that how life is related to ancestors. Charles Darwin first uses this in the modern biology. It is an evolutionary tree that depicts the relationship between various biological entity. It holds the data that are collected from RNA, DNA and protein analysis. It shows the current hypothesis about the evolutionary relationship among the taxa.
Hence, the correct answer would be option A.
Answer:
Answered below.
Explanation:
The fossil records are beneficial in giving us. wide range of knowledge about fossils but sometimes these records are flawed, in that they are incomplete or misleading.
Many of the fossil records available are incomplete because some animals tend to decay within a short period of time due to their soft tissue. Also some are destroyed due to the movement of tectonic plates over time.
Another flaw scientists encounter is that there are no fossils which illustrate or represent the orderly transition from one organism to another. Fossils generally do not support the Darwinian theory of evolution as no evidence is found of ordered, sequential transition from simple to complex life forms as postulated.
These flaws are significant because they influence our knowledge and understanding of life forms and evolution.
Answer:
it could not be used because it can attracts the magnets in which compass it self is a form of magnet which can utilize the magnetic properties of the earth to give a reading and Compass housings are often made of either brass, aluminium or plastic.
Explanation:
The characteristic of iron that would make it a bad material for the housing around a compass is that it could not be used because it can attracts the magnets in which compass it self is a form of magnet which can utilize the magnetic properties of the earth to give a reading reason been that Compass housings are often made of either brass, aluminium or plastic
Secondly it would confuse the magnet thereby making it un-useful or useless because the iron can easily become magnetized itself and Iron is a magnetic metal which can cause the needle of a compass to give a false reading thereby messing up the magnet's direction and making it useless.
Is the problem true of false
