it's (+/-) 90 degrees. in total it's 180 but the equator is at zero and the two hemispheres have 90 each
Answer: they will separate into different cells.
Explanation:
They separate into 4 cells.
Answer:
The study of evolutionary relationships that includes a branching pattern showing lineages diverging is called <em>phylogenetic tree</em>
Explanation:
The phylogenetic tree is composed of,
• Lineages → These are the taxonomic groups of interest placed in the extremes of the lines called branches.
• Nodes → These are the ramification points, which are also known as divergence points. They represent the location of the most recent common ancestor.
• Root → This is the older common ancestor that all lineages share. The first one in the tree.
Two or more lineages are more related to each other if they share a recent common ancestor. This means that they all diverge from the same node.
Two or more lineages are less related to each other if they lack a recent common ancestor. This is, the node from which these lineages diverge is placed far away in the tree.
There are also different phylogenetic relationships between lineages.
• Apomorphies → Occur when the involved lineages share a trait that they inherited from their most recent common ancestor. This trait evolved for the first time in this ancestor. → This relationship is a homology.
• Plesiomorphies → occur when the involved lineages share a trait inherited from a common ancestor, but that is older concerning the present traits exhibited by other descendants of the same common ancestor. → This relationship is a homology.
• Homoplasy → Lineages share a trait that evolved independently in each group. → This relationship is an analogy.
Many factors that determine weather genes are "turned on" are in the environment in the form of <span>social and cultural influences.</span>
