Why would it be hard to outline the entire history of the United States on the geologic time scale?

In Illinois, the two most common crops grown are corn and soybeans. Corn is a that depletes the soil of nitrogen. Soybeans are a

Answer:

Farmers definitely use the information above to plan out their crops from one year to next.

Explanation:

Nitrogen is an essential nutrient required for healthy plant growth. Corn is an important food crop and after its cultivation the soil is depleted of its nitrogen. Cultivation of any crop on soils that lack nitrogen will not yield good result.

Thus the nitrogen in the soil has to be replenished. Soybean is a crop that has symbiotic bacteria living on its roots. This bacteria help in fixing atmospheric nitrogen. Thus the nitrogen level will get replenished.

Thus cultivating soybean on the land in the period between harvest and sowing of corn would be a healthy practice that increases yield and maintains soil health.

The bacterium bacillus thuringiensis can withstand heat, dryness, and toxic chemicals that would kill most other bacteria. this

Sedaia [141]

Endospore is a protective structure that can able to survive for long periods of time in soil and water in which they commonly found. They are tough, dormant and non-reproductive structure which can withstand heat, dryness, and toxic chemicals that would kill most other bacteria produced by a small number of bacteria like the bacterium Bacillus thuringiensis from the Firmicute family. To ensure the survival of a bacterium through periods of environmental stress is the primary function of most endospores. They are also resilient to gamma and ultraviolet radiation, chemical disinfectants, desiccation, starvation, lysozyme and temperature and can survive any environmental assaults.

A high concentration of chlorophyll imbedded in the plasma membrane fold of a newly discovered species of bacteria suggests a: A

bearhunter [10]

Answer:

C. Photoautotrophic metabolism

Explanation:

Chlorophyll helps in the photosynthesis process and it is main site where photosynthesis is happening. During photosynthesis, chlorophyll capture sunlight energy and transform Carbondioxide into glucose , which is the main energy source for an organism. So if the chlorophyll is present in a bacteria, it means it is going through photoautotropic metabolism.

The two primary jobs of parenchyma cells are _____. flexibility photosynthesis support transport food storage

gregori [183]

Role of Parenchyma cells-

The two primary jobs of parenchyma cells are food storage and transport.

Parenchyma cells-

Parenchyma cells are cells that are living. These cells also have really thin-walls and a structure that is unspecialized. These cells can therefore perform a variety of functions. Parenchyma cells are present throughout a plant. These are present in the form of tissues which are homogenous. Parenchyma cells are present in both the stem and roots. This is the primary reason these cells are involved with the assimilation of nutrients and food. These cells are also present in the flesh of fruits and in seeds, and in the mesophyll of leaves which is why these cells can store food.
