Nitrogen fixation makes nitrogen gas useful to crops.

true or false

True

Explanation:

The nitrogen fixation is a process that involves conversion of atmospheric nitrogen to nitrates in the soil. This process is mainly performed by nitrogen-fixing bacteria present in the soil.

The nitrogen fixation is important for plants and animals. The nitrogen present in the atmosphere cannot be used directly by animals and plants. The nitrogen is main constituent of chlorophyll that is required for the process of photosynthesis and for amino acids that synthesize proteins. Thus, Nitrogen fixation makes nitrogen gas useful to crops.

starchy vegetables are high in carbohydrates.

starchy vegetables contain more carbohydrates than non-starchy vegetables.

explanation:

there are two primary categories of carbohydrates, essentially differentiated on the basis of their carbohydrate content (which is in the form of starch - a complex carbohydrate):

those vegetables which contain little amounts of starch are termed as non-starchy vegetables, and some examples include: artichokes, broccoli and bean sprouts.

vegetables high in their starch content are distinguished as starchy vegetables, and some examples include: potatoes, chickpeas and corn.

the alkaline earth metals (beryllium (be), magnesium (mg), calcium (ca), strontium (sr), barium (ba), and radium (ra)) are a group of chemical elements in the s-block of the periodic table with very similar properties: shiny. silvery-white. hopefully this ? i didn't fully understand the question
