<h2>Sugar beet harvest </h2>
Explanation:
Sugar beets have to be harvested and stockpiled in September because they have to get the root out of the ground before the ground freezes
- Sugar beets are harvested with two primary pieces of equipment
- The defoliator removes the green leaves and slices a slab from the top of the sugar beet root
- This removed slab is the growing point of the sugar beet and contains high levels of impurities, which impede the factories ability to extract the sugar from the remainder of the harvested root
- The sugar beet root is then harvested with a pinch wheel harvester, which pinches the root and lifts from the soil
- The sugar beet harvester also separates some soil and conveys the sugar beet into a truck to be transported to a receiving station
The main benefits of the monoculture farming are that it has higher production, is more efficient, and has lower costs. All three advantages of the monoculture farming are making it much more attractive for the farmers as it is more profitable and easier for work.
In this type of farming there's no spaces of the arable land that are lost because it is all planted with the same culture, and there isn't any other cultures with which there should be made empty spaces in between.
The costs for farming are lower, and also the work is easier and more efficient because the machinery can be used in the same manner constantly and the work can go on systematically on the farmlands.
On the other hand, we have to mention that there are also negative effects of this type of farming like the total destruction of animal and plant biodiversity in the area where it is practiced, as well as making the entire crop vulnerable to diseases and environmental changes.
Pros:
It is (mostly) based on pyrethrine spray which kills the
insects rapidly.
It not poisonous to other animals.
It uses synthetic, natural spray which is safe to use because
it breaks down within 10 minutes.
Te technique can reach tall forests.
It can be used in closed spaces ( greenhouses, basements
etc).
Cons:
It requires windless circumstances ( which is mostly at
nights).
Breathing fog may cause respiratory and throat irritation to
some.
Answer:
The correct answer is option a.
Explanation:
Yes, the light reactions also depend upon the Calvin cycle. Calvin cycle refers to a phenomenon that is used by the plants and algae to convert carbon dioxide from the atmosphere into sugar, the food needed by the autotrophs in order to grow. The plants rely upon the Calvin cycle for food and energy.
In the given case, the rate of oxygen production would get diminish as the rate of ATP and NADP+ generated by the Calvin cycle diminishes. Of all the outcomes of the Calvin cycle, ADP and NADP+ are the only ones that get utilized by light reactions.
The ADP and NADP+ are used up by the light reactions to fuel their reactions. This illustrates that if the rate of ADP and NADP+ generated by the Calvin cycle diminishes the production of oxygen by the light reactions also diminishes.
The answer is they produce endospores.
Explanation:
The endospores are dormant, non-reproductive, tough bacterial spores that ensure the survival of bacteria in adverse conditions.
During the environmental stress, such as starvation, desiccation, radiation and chemical treatment many bacteria form dormant endospores. These endospores germinate again when the conditions become favorable.
Hence, if drought conditions lead the stream to dry up, the bacteria that live there would produce endospores to survive.
