The phylogenetic tree shown here displays the major clades of chordates.
Which statements about the phylogenetic tree are true?
A) Organism (c) is a common ancestor of lampreys and lungfishes.
B) Birds and ray-finned fishes have a notochord and jaws.
C) Lancelets and coelacanths are more closely related than are chimaeras and coelacanths.
D) Mammals and turtles are more closely related than are lungfishes and sharks.
E) Rays and frogs have vertebrae.
F) Descendants of organism (d) have limbs with digits.
G) Hagfishes, lungfishes, and frogs have lobed fins.
H) Organism (a) is a common ancestor of all chordates.
Answer:
B, D, F, E, H.
Explanation:
A phylogenetic tree is a diagram representing evolutionary relations between species. Phylogenetic trees are not conclusive evidence nor theories. In a phylogenetic tree the pattern of branching illustrates how organisms or other groups developed from a set of similar ancestors.
Some of the examples of phylogenetic tree are as following:
- A notochord and jaws includes in birds and ray-finned fishes.
- Mammals and tortoises are closer to one another than lungfish and sharks are.
- Organic Descendants (d) have wings.
- Rays and frogs are columned vertebrally.
- A shared ancestor of all chordates is the organism (a).
Hence, the true options are B, D, F, E, H.
<u>Given:</u>
Present population of bison = 3652
Maximum growth rate = 0.28
<u>To find:</u>
The population of bison after one year.
<u>Solution:</u>
The future population can be calculated with the help of the following formula,
where is the future population,
is the present population, r is the growth rate and n is the number of years.
On substituting the given values in the formula we get,
Therefore, the population size of bison after one year is 4675. The park does not have to control the population because the growth rate is on an average scale.
