different seeds need different cultivation. justify in 200 words.

for 18 points​

Answers

Answer:

Cultivation is the process of growing crops. we need different seeds to cultivate different types of food. Similarly, different seeds need different cultivation. For eg: we grow potatoes in well-drained loam soil. But we grow rice in muddy soil. Every seed has a different way to produce food. They need different temperate or climates, different types of soil, to grow them. They have their own time or season to grow and produce food. If we try to grow plants or vegetables in the wrong season or the wrong process, then we can't get a good result. For eg: If we try to grow rice in drained soil then it will not give us a good result or if we try to grow potatoes in muddy soil we cant get our good result.

So, we can say that different seeds need different cultivation.

Give a reason why lack of roughage in diet often lead to constipation?​

Answers

Answer:

Roughages increase fecal volume and promote peristalsis

Explanation:

Constipation refers to the condition in which bowel evacuations occur infrequently, leading to health problems. Some of the most common causes of constipation include 1-insufficient intake of dietary fibers or roughages, 2-poor hydration, 3-lack of physical exercise, 4-abuse of laxatives, etc. Dietary fibers are divided into two classes based on their water solubility: soluble and insoluble. These fibers represent the part of plant foods that the body can't digest, which absorbs and retains water (soluble fibers) as foods pass through the bowel and create bulk (insoluble fibers), thereby leading to regular bowel habits.
