Answer:

Tidal power and current power

Explanation:

First, we can determine that A and B are obvoiusly wrong. Ocean thermal energy produces zero carbon emissions, as most forms of hydroelectric power do. Secondly, wave energy might affect aquatic life, but it wouldn't affect the migration of birds. After reviewing the 3rd and 4th answers, they do look reasonable. Therefore, your answer is tidal power and current power.

inna [77]

Answer:

In the extracellular space

Explanation:

Disulfide bonds are interconnections between chains (or between parts of a chain) formed by the oxidation of cysteine ​​radicals, this reaction is catalyzed by specific enzymes.

Intracellular proteins have no disulfide bonds, which are more common in proteins secreted into the extracellular environment.

Disulfide bonds do not form in the cytoplasm because there are a lot of reducers in the cytoplasm (intracellular environment) , making the disulfide bonds unstable. The reducing environment of cytoplasm causes disulfide bonds (S-S) to return to the form of cysteine ​​groups (-SH).

Arturiano [62]

Granite is a type of intrusive igneous rock

Explanation:

An igneous rock formed from hot magma or lava cools, solidifies or crystallizes to form rocks.

Based on the rate of cooling of magma, igneous rocks can either be intrusive or extrusive.  

A slow cooling of the magma deep within the earth without reaching the surface of the volcano leads to the production of intrusive igneous rocks.

This slow cooling leads to crystallization forming large crystals visible to the eyes with a phaneritic texture.

Granite has the best phaneritic texture among intrusive igneous rocks. Granite crystals can be easily visualized and are constituted by minerals like white feldspar, black hornblende, translucent quartz, and platy black biotite.

Extrusive igneous rocks like basalt are formed from microscopic crystals from fast cooling of magma.
