Tillage can release pollutants in the soil and
increase erosion.
decrease erosion.
promote soil compaction.
promote fertilizer retention.
Tillage can release pollutants in the soil and increase erosion by the acceleration of the soil and wind speed.
How doesTillage can increase erosion ?
Tillage can split soil structure, pace the decomposition and lack of natural matter, boom the hazard of erosion, break the habitat of useful organisms and reason compaction.
Each of those capability effects negatively effect soil fine. A soil's overall performance is immediately associated with a soil's fine or health. Since tillage breaks the soil, it disrupts soil structure, accelerating floor runoff and soil erosion. Tillage additionally reduces crop residue, which assist cushion the pressure of pounding raindrops.

Answer:
Single celled organisms are made up of one cell, often microscopic and limited in size, able to meet all challenges of life with in one cell, and are able to differentiate to perform a specific job.
Explanation:
Singled celled organisms are usually, as the name suggests, single celled. To see one, you must use a microscope, and usually range anywhere from 0.5 to 10cm tall. A single celled organism can preform the necessary functions for life. They can eat, breathe, grow, and do other things other organisms with more than one cell.

In Madagascar scientists have discovered a moth, xanthopan morganil praedicta, that has a 30.5 cm proboscis and feeds from and pollinates Darwin's orchid, angraecum sesquipedale. The orchid has a nectar - producing tube that is 27.9 cm long. How is the moth's proboscis size an adaptation for its environment?
The size of the proboscis helps the moth to consume the food (nectar) easily from Darwin's orchid.
What do you mean by Adaptation?Adaptation may be defined as the process of modifying one's characteristics to better suit a situation and survive more efficiently.
The size of the tube that produces nectar is just 27.9cm long, while the length of the proboscis of a moth is 30.5cm. It easily consumes the nectar and gets energy for survival as well as reproduction.
Therefore, the size of the proboscis helps the moth to consume the food (nectar) easily from Darwin's orchid.

3. Which type of photosynthesis is not reliant on the presence of light to be efficient?
Answer:
[tex]C_{4}[/tex]
Explanation:
C4 plants incorporate carbon dioxide into malate, a four-carbon compound, before it enters the Calvin cycle. C4 plants sequester RuBisCO and the Calvin cycle enzymes in the leaf bundle sheath cells, while RuBisCO occurs throughout the mesophyll of C3 leaves.
this diagram illustrates the three types of plant tissue.
Which main plant tissues are the lines pointing to the enlarged diagram?
The main plant tissue that the lines in the enlarged diagrams point to is the ground tissue.
What are ground tissues in plants?Ground tissues in plants refer to the collenchyma tissues, the parenchyma tissues, and the sclerenchyma tissues.
In other words, they are tissues that are neither dermal nor vascular in origin.

light harvesting complex 1
Light-harvesting complex 1 captures the light energy from the sun and transfers it to the reaction center for the induction of redox processes.
How many types of light-harvesting complexes are there?There are two types of light-harvesting complexes which are most commonly known. LHC-I surrounds photosystem I, and LHC-II that surrounds photosystem II of the membrane.
LHC-I is dimeric in nature that is tightly bound to the photosystem I of the thylakoid membrane. It assists the photosystem I to receive the far-red light and releases its electrons.
Therefore, it is well described above.
