Number 6 is D, However Number 7 is not humus. They are contributing to the formation of silt. Which is kind of like a fertilizer.
Answer:
Please find the definition of viscosity, effect of heat on DNA explanation to this question below
Explanation:
Viscosity is a term used to describe FLUIDS, which includes liquids and gases. Viscosity refers to the ability of a gas or liquid to resist flow. In other words, it is the measure of the internal friction that exists between the molecules of a fluid, which resists its flow.
DNA in its natural state exists in a liquid solution, hence, when HEAT is applied, the heat causes ITS MOLECULES to MOVE RELATIVELY FAST and as a result the molecules lose the friction between them and begin to flow. Based on this, heat is said to make DNA LESS VISCOUS i.e. to flow more rapidly.
There are 2 types of photoreceptors rods and cones they react to light in different ways.
Rods-
Respond to low levels of light and are primary responsible for night vision.
They are poor at detecting fine details in an image and are not involved in colour vision.
Cones-
Respond to high levels of light and are primary responsible for our vision in well-lit conditions.
They detect fine details and are responsible for colour vision.
Unlike the carbon cycle, the phosphorous cycle does not involve a gas phase and is therefore not considered as a true cycle. This is what distinguishes it also from such cycles as the water and nitrogen cycles.
Very little phosphorous circulates in the atmosphere because at earth's normal temperatures and pressure, phosphorous together with its various compounds are not in gaseous form, though small amounts of phosphoric acid may make their way into the atmosphere, and contributing to acid rain in some cases.
The largest reservoir of phosphorous is in sedimentary rock.
Likely if you harm the ribosomes the cell will die. Cells absolutely require ribosomes for normal functioning...they are constantly replacing proteins (including enzymes and the ribosomal proteins) to keep alive.
