Before starch can enter a cell it must be digested to form simple sugars. Why?
Nataliya [291]
Starch is a high molecular weight substance; therefore, it is insoluble to our cells. It needs to be broken down to simple sugars like glucose in order for it to be dissolved/absorbed in our blood. This is because simple sugars has smaller molecular weights and are more soluble.

Which of these are the two major sources of nitrate pollution in rivers?
nikklg [1K]

Answer:

The correct answer is <em>c. animal wastes and fertilizers. </em>

Explanation:

Two major sources of nitrate pollution are farming and breeding activities. There are also certain industrial activities involved in nitrate pollution, but in general, these industries are related to agriculture.

The indiscriminate use of fertilizers for several years in intensive productions produce high nitrate concentration in soil and consequently elevate the risk of nitrate lixiviation.

Breeding animals produce nitrate pollution by their wastes, which accumulate and are not treated. These wastes include flesh, hair, feathers, skin, fat, liquids, excrements, among others. These wastes are an important source of nitrate.

In many cases, animal wastes are used by farmers as organic matter to improve their production. But excessive and incorrect use of it might produce severe damage in water sources.

why is it important that biology studies the interactions of organisms with both their environments and other organisms
Lyrx [107]

Answer:

Ecology can be described as the branch of biology which is related to the study of the interaction of an organism with other organisms and the environment. This study is important because both biotic and abiotic factors play a vital role in the existence of an organism. Abiotic factors such as soil type, food resources, water resources, amount of sunlight reflect which organisms will be able to live in an area. Biotic factors also influence the life of an organism just as the abiotic factors do.
