In insects what does hemi metabolism indicate
ArbitrLikvidat [17]

The hemi metabolism<span> indicates the three distinct stages of the life cycle of some insects: the egg, nymph, and the adult stage, or imago. It has no pupal stage just like the complete metamorphosis that undergoes pupal stage before turning into adult. Insects that undergo hemi metabolous metamorphosis go through gradual changes; develop from eggs into nymphs sometimes called larvae by some entomologists, that are similar in shape to the adults. You can distinguish the nymphs from the adults by looking for wings. Wing buds or wing pads may be present in late stage nymphs, but they are fixed in place against the body and are non-functional compared to the adults whose wings are fully developed. </span>

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

nexus9112 [7]

Answer:

The results are useless

Explanation:

The alkaline/alkaline results could indicate that only the protein was utilized by the organism, but it could also be a result of prolonged incubation. The organisms could have exhausted that available sugar and then reverted to protein catabolism.
