convert 5mL to hectoliters (conversion factor: 1mL= 0.00001 hectoliters)
-50 hectoliters
-0.5 hectoliters
-0.005 hectoliters
-0.00005 hectoliters
Taking into account the change of units, the correct answer is the last option: 5 mL equals 0.00005 hectoliters.
Rule of threeThe rule of three is a way of solving problems of proportionality between three known values and an unknown value, establishing a relationship of proportionality between all of them.
If the relationship between the magnitudes is direct, the direct rule of three must be applied with the following formula must be followed, being a, b and c known data and x the variable to be calculated:
a ⇒ b
c ⇒ x
So: x= (c×b) ÷a
The direct rule of three is the rule applied in this case where there is a change of units.
Change of units in this caseTo perform in this case the conversion of units, you must first know that 1 mL= 0.00001 hectoliters.
So, you can apply the following rule of three: if 1 mL equals 0.00001 hectoliters, 5 mL equals how many hectoliters?
1 mL ⇒ 0.00001 hectoliters
5 mL ⇒ x
So: x=(5 mL× 0.00001 hectoliters)÷ 1 mL
Solving:
x= 0.00005 hectoliters
In summary, the correct answer is the last option: 5 mL equals 0.00005 hectoliters.

lidar based biomass and crop nitrogen estimates for rapid, non-destructive assessment of wheat nitrogen status,"
In early development green TLS can be helpful to enhance nitrogen management.
To enhance nitrogen management decisions, crop nitrogen optical remote sensing is being developed for diagnostic use. To calculate the nitrogen nutrition index, dry mass per unit area of nitrogen and concentration functions are taken. NNI is the ratio of the actual concentration of nitrogen in percent and minimum nitrogen concentration in percent. During stages of early growth, to know crop nitrogen status optical remote sensing is essential. But there are high risks of errors because of the influence of soil spectral reflection.
If TLS point data are used for deriving the actual concentration of nitrogen from green and quantifying physical W in Terrestrial LiDAR then this can pacify the errors. In an experiment, Green TLS measurements of winter wheat for two seasons were collected. Based on the experiment, it was observed that there exists a strong relationship between the intensity return of green laser and % Na.

Most prairies experience regular fires, typically every few years. If these disturbances were relatively modest, how would the species diversity of a prairie likely be affected if no burning occurred for 100 years? Explain your answer.
If fire disturbances were relatively modest, then the species diversity of a prairie likely would be affected because certain adapted species might exclude less competitive species.
What is the effect of modest fire on ecological succession?The main effect of modest fire on ecological succession is to maintain species that otherwise would be eliminated and therefore it affects diversity by hampering the succession of less competitive species in the area.

When your first child is six months old, you hang a tire swing from a tree limb in your backyard. The bottom of the tire is six inches from the ground. When your child graduates college 22 years later, the tree is now ten feet taller than it was when you hung the tire swing. Neglecting soil erosion and any increased thickness of the limb, how far from the ground is the bottom of the tire?.
There will be about 6 inches between the bottom of the tire which is hanging in the branch of the tree and the ground.
The primary cause of this is because a tree's development always takes the shape of radial growth. In this case, the axis of the tree or plant continues to produce additional branches.
The leaves continue to develop, and the primary branch produces several other little branches. There are two ways that trees grow. Primary growth refers to growth that occurs at the root and shoot tips and results in height and length increases.

Explanation:
Scientists often use measures of "higher-order thinking" to assess intelligence in other animals. For example, birds are judged to have sophisticated thought processes because they can use tools and make use of abstract concepts. What problems do you see in defining intelligence in these ways?
Animals with higher intelligence have certain brain features that make them smarter. The neocortex is one of these, and it is necessary for complex cognition. Animals such as birds are less intelligent because they lack these structures..
Briefing:All mammals have a neocortex, albeit the neocortex's dimensions and structural makeup vary widely among mammalian taxa. The neocortex performs cognitive, perceptual, logical, and motor control activities.
Are there neocortex in birds?There is no neocortex in the tiny brains of birds, and they have different structures and connections than primates do. This should not come as a surprise considering that more nearly 200 million years ago, birds diverged from the evolutionary pathway that led to mammals, then to primates, and ultimately to humans.

What is the difference between effector B cells (plasma cells) and cytotoxic T cells?
When B cells interact with any antigens it gets divided into B plasma cells and B memory cells. Plasma B cells produce antibodies against antigens or pathogens found in the blood. These antibodies bind to the antigen's epitope and aid in its destruction by phagocytic cells.
Pathogen elimination by cytotoxic T cells is a completely different process. Cytotoxic T cells bind to pathogen-infected cells and release cytotoxic enzymes that kill the pathogen-infected cell.
As a result, B-cells secrete antibodies against pathogens, and cytotoxic T cells kill pathogen-infected cells.

the disease called multiple sclerosis involves an immune response against myelin of the central nervous system, causing scar formation (sclerosis) within the neural tissue. how would this affect nerve impulse conduction?
In multiple sclerosis the impulses are suppressed or stopped causing scar formation (sclerosis) within the neural tissue.
Multiple sclerosis (MS) can paralyze the brain and spinal cord (central nervous system). Myelin, the protective sheath that protects nerve fibers, is attacked by the immune system in MS, affecting communication between the brain and body. This condition can eventually lead to neurodegeneration or irreversible disability. Signs and symptoms of MS vary widely, depending on the degree of nerve damage and the nerves affected. Some people with multiple sclerosis lose the ability to walk on their own or become unable to walk at all, while others walk long distances without developing new symptoms. Axons are properly protected by the myelin sheath and these neurons perform their intended function. When the myelin sheath is destroyed in multiple sclerosis-affected nerves, the nerve axons become demyelinated.Therefore, blockage of impulses is the correct answer.
