PLEASE HELP! (c) Complete the table to represent the relationship between volume and surface area of a spherical structure surro
Anuta_ua [19.1K]

Answer/Explanation:

Recall:

Volume of a sphere = ⁴/3πr³

Surface Area = 4πr²

✔️For radius (r) = 1 mm:

Volume = ⁴/3 × π × 1³ = 4.19 mm³

Surface Area = 4 × π × 1² = 12.57 mm²

Ratio of volume to surface area = 4.19 : 12.57 = 1:3

✔️For radius (r) = 3 mm:

Volume = ⁴/3 × π × 3³ = 113.1 mm³

Surface Area = 4 × π × 3² = 113.1 mm²

Ratio of volume to surface area = 113.1 : 113.1 = 1:1

According to the theory of island biogeography, which of the following is not an island ecosystem?
den301095 [7]
<span>The correct answer is b. The open ocean. The definition of an island ecosystem does not have anything to do with water, but simply refers to an ecosystem that exists as a microcosm within a far larger, separate ecosystem. The ocean has lots of separate island ecosystems within it, but it itself cannot be referred to as one.</span>

Provide the term for base triplets on tRNA
Semmy [17]
The answer is anticodon.

Anticodons are base triplets on transfer RNA (tRNA). t<span>RNA carries amino acids to the ribosome for protein synthesis. </span>The prefix<em> anti-</em> suggests that anticodons are complementary to the codons on mRNA. Codons are base triplets on mRNA. So, anticodons of tRNA pair with codons of mRNA in the process of protein synthesis.
