Imagine that you are studying alien life-forms discovered on a distant planet. While geneticists are working out the genetic cod

e of these organisms, you are asked to construct a phylogenetic tree based on four morphological features, or characters: presence or absence of a spring tail, presence or absence of a grasping hand, presence or absence of a second tail, and number of eyes. The organisms have been divided into five groups based on these characters.

A phylogenetic tree based on morphology can be constructed using the presence or lack of characteristics. In this illustration, all aliens except the outgroup possess a spring tail, all aliens possess a fourth eye, two aliens possess two tails, and one alien has a grasping hand. The evolutionary relationships between these organisms can be hypothesized using these traits.

Aliens:

  • We can determine whether the following traits are present in the remaining aliens by using the group of aliens with the tail stalk as our test group.
  • Out group: a group that is maintained apart from the clade but is yet connected to it.
  • If we provide these aliens alphabets for ease of understanding, then aliens will be like in order.
  • We can use the group of aliens with the tail stalk as our test group to see if the following characteristics are present in the remaining aliens.
  • A group that is kept separate from the clade while yet being affiliated with it is known as an out group.
  • The aliens will appear to be in order if we give them alphabets for simplicity.

victus00 [196]

Answer:

Veins.

Explanation:

Heart is the main organs of circulatory system that transport blood in the body.Human heart is four chambered and separates the oxygenated and deoxygenated blood in the body.  

Arteries are responsible for the passage of blood from heart to the body parts. The deoxygenated blood from the body collect in the veins and transfer to heart. Arteries has high pressure than veins and veins are thinner than artery.

Which of the following is not true regarding the denaturation and reannealing of double-stranded DNA molecules? Which of the fol
aleksley [76]

Answer: "Decreasing the salt concentration of the solution lowers DNA's melting point (Tm)" is not a true statement

Explanation:

Increasing salt concentration would lower the DNA's melting point (Tm), not otherwise.

For instance:

- In 8M urea (8M means 8 Moles per dm3), Tm is decreased by nearly 20°C.

- 95% formamide at room temperature would completely denature the double stranded DNA.

Thus, higher concentration of salts like urea or formamide lowers Tm, not otherwise
