What is the best basis for analyzing/mapping evolutionary hostory​

Answers

Answer 1
Answer:

Answer:

https://en.wikipedia.org/wiki/Phylogenetic_tree. Try this link.

Explanation:

The best basis for mapping evolutionary history would be a phylogenetic tree.  This "tree" shows the relationship between every biological species on Earth in reference to their origin...In evolutionary terms, a common ancestor. This tree also takes into consideration the genetic and physical traits and differences in every species and organism on the tree. Hope this helps : )!
Answer 2
Answer:

well you should start maybe a time line OR,  In the case of phylogeny, evolutionary investigations focus on two types of ... a high percentage of bases in the same locations, causing these organisms to appear ... history of species, our own included, phylogenetic analysis has ... made recommendations for conservation

Which choice is involved in both sexual and asexual reproduction?seeds


sperm


spores


eggs

Answers

The choice that is involved in both sexual and asexual reproduction is the spores that are in the third option, as the others are involved in sexual reproduction, such as the sperm, egg, etc.

What is the advantage of sexual reproduction over asexual reproduction?

Both types of reproduction have advantages, for example, if a mutation occurs and becomes genetic, the chance of getting the disease is lower in sexual reproduction than in asexual reproduction. The possibility of recombination and crossing over reduces the rate of genetic disorders in sexual reproduction, whereas in asexual reproduction, the mutation passes from one to the other.

Hence, the choice that is involved in both sexual and asexual reproduction is the spores that are in the third option, as the others are involved in sexual reproduction, such as the sperm, egg, etc.

A 45 g piece of plasticine is placed in water and 30cmcube of water was displaced. Calculate the density of the plasticine in kg/mcube

Answers

Answer: 1500kg/m^3

Explanation: Assuming the cube was not large enough to float if it displaced 30cm^3 of water then it has a volume of 30cm^3. Density is just mass/volume so 45g/30cm^3 = 1.5g/cm^3. To convert this to kg/m we need to multiply by the conversion factors of the units. 1.5g/cm^3 • 1kg/1000g • 1,000,000cm^3/1m^3 = 1500kg/m^3.
