Hi,
Answer: B) Convergent
<u>My work:</u> A convergent boundary is when two plates collide. DTrnches are usaully made out of a convergent boundary.
I Hoped I Helped!
The scientists should conclude that other data must be considered in order to make a valid conclusion.
<h3>What is Archaefructus?</h3>
Archaefructus is an extinct genus of herbaceous aquatic seed plants with three known species. Fossil material assigned to this genus originates from the Yixian Formation in northeastern China, originally dated as late Jurassic but now thought to be approximately 125 million years old, or early Cretaceous in age.
Even with its revised age, Archaefructus has been proposed to be one of the earliest known genera of flowering plants.
Because of its age, lack of sepals and petals, and the fact that its reproductive organs (carpels and stamens), are produced on an elongate stem rather than condensed into a flower as in modern angiosperms,
Archaefructaceae has been proposed as a new basal angiosperm family.
An alternative interpretation of the same fossil, however, interprets the elongate stem as an inflorescence rather than a flower, with staminate (male) flowers below and pistillate (female) flower above.

Answer:
<em>Produce offspring!</em>
Explanation:
The function of a reproductive system is to produce offspring the male gives the female the sperm while the female tends to it within her reproductive system!

Long strands of double-helical DNA fit into the nucleus of a single cheek cell, the double helix is packaged and wrapped around proteins, folded back onto itself and coiled into a compact chromosome. 4.
Answer:
Interaction between hydrophobic (nonpolar) amino acid side chains is due to hydrophobic interactions.
Repulsion between negatively charged backbone of DNA double helix is due to electrostatic repulsion forces.
Interaction between water and carbonyl oxygen of guanine is due hydrogen bonding
Explanation:
The hydrophobic effect refers to the tendency of non-polar substances forms aggregates in an aqueous solutions in order to avoid interactions with water molecules. This results in a favorable entropy increase.
For non-polar amino acids, hydrophobic interactions are important in stabilizing their structure wherein they are densely packed within the core of a protein while those with with polar groups are found in the exterior.
The phosphate backbone of DNA is negatively charged. Since like charges repel, therefore, electrostatic repulsion forces of the ions are responsible the repulsion of the backbone DNA double helix.
Hydrogen bonds are formed between electronegative oxygen atoms and hydrogen atoms of neighboring molecules due to the partial negative and positive charges on each of the atoms.
This hydrogen bonding is responsible for the interaction between water and carbonyl oxygen of guanine as the hydrogen atoms of the water molecules are attracted to the oxygen atoms of the guanine molecules due to the partial charges on each of the atoms.
