Explanation

When an alcohol reacts with an alkyl magnesium halide (Grignard reagent), the product is an alkane.

The Grignard reagent acts as a strong base, removing the acidic hydrogen from the alcohol's hydroxyl group (-OH) and forming a new carbon-hydrogen (C-H) bond, thus creating an alkane.

The other product is a magnesium alkoxide salt. 

Explanation

Sodium (Na) and Chlorine (Cl) together make up about 0.45% of the human body mass.

They are essential electrolytes that help regulate fluid balance, nerve function, and muscle activity.

Explanation

Explanation

 The bond between a fatty acid and glycerol is called an ester bond.

This bond forms when the hydroxyl group (-OH) of glycerol combines with the carboxyl group (-COOH) of the fatty acid, releasing a molecule of water (H2O) in a process called dehydration synthesis.

Explanation

Chloroform is classified as a possible human carcinogen, particularly linked to liver and kidney cancer with prolonged exposure.

It affects the liver by causing cellular damage.

It has been shown to induce tumors in animal studies.

Explanation

The transpose of a row matrix is a column matrix.

Similarly, the transpose of a column matrix is a row matrix.

In essence, when transposing a matrix, you swap rows with columns.

So, a matrix with one row becomes a matrix with one column, and vice versa.

Explanation

Cyanobacteria utilize phycobilins, specifically phycocyanin (blue) and phycoerythrin (red), as accessory pigments in addition to chlorophyll a.

These pigments help cyanobacteria absorb light across a wider range of wavelengths than chlorophyll a alone, enhancing their photosynthetic efficiency.
