You complete an experiment measuring the spread of the Cordyceps fungus across a forest environment. You measure the amount of g

rowths you observe on the ground in a 1 acre area. After evaluating your experiment, you find that fungus frequently grows long fibers underground and only sprout reproductive parts above ground. How might this affect your data and/or conclusion?
A. The data is accurately measured so this does not affect the conclusion.
B. The data will have many outliers because of the underground growth and will not be accurate.
C. The data does not take into account underground growth and the actual area of fungus spread may be larger, so the original conclusion of the experiment is not accurate.
D. The data should be recounted to include the underground growth and the outliers will make the data more reliable

Answer: C. The data does not take into account underground growth and the actual area of fungus spread may be larger, so the original conclusion of the experiment is not accurate.

Explanation:

A fungus is a saprophytic organism which feeds over dead and decaying organic matter generated after the death of plants, animals and other living beings. The fungus exhibit a vegetative body which lies above the surface of ground which is responsible for reproduction by sexual and asexual modes. It exhibit thread like structure called as hyphae. The hyphae is penetrating in nature that penetrates the layers of soil so as to derive nourishment from the dead and decaying matter.

According to the given situation, the data will be incorrect to answer the fact that the total area covered by the fungus as the fungus not only grows above the ground but also covers the area underground. Hence, C is the correct option.

anyanavicka [17]

Answer:

1. ridges and trenches (either answer is acceptable)

2. mid-atlanitc

3. subduction zone

4. molten

5. oceanic trenches

Explain:

6. Rocks in the ocean eventually get subducted back into earths mantle due to slab pull. New rocks form at mid-ocean ridges as ridge forces two plates to diverge.

Virgin queens will only exit the hive for her mating flight(s) if the following condition is met: _________
Verdich [7]

Answer:

The correct answer is "the temperature is above 23 °C but not exceeding 40 °C".

Explanation:

The main function of virgin queens in a bee's hive is reproduction. Normally virgin queens do not exit the hive except to perform mating flight(s), which normally are done with 10–20 drone bees and then return to the hive as mated queen bees. Usually virgin queens perform her mating flight(s) in ideal temperature conditions, which are with a temperature above 23 °C but not exceeding 40 °C.

An owl has good night vision because its eyes can detect a light intensity as small as 5.0 × 10-13 W/m2. What is the minimum num
Lady bird [3.3K]

Answer:

Thus, the minimum number of photons per second is 77.34

Explanation:

Light intensity, I_{min} =  5\times 10^{-13} W/m^{2}

Pupil has a diameter, d = 8.5 mm

                                      = 8.5 x 10^{-3} m

Radius of the eye, r = 4.25 x 10^{-3} m

∴ Area of the eye, A = \pi .r^{2}

                                 = 3.14\times \left ( 4.25\times 10^{-3} \right )^{2}

                                = 5.6\times 10^{-5} m^{2}

Let P_{min} be the minimum number of photons.

Therefore, P_{min} = I_{min} x A

                                              = 5\times 10^{-13} x 5.6\times 10^{-5}

                                             = 2.8\times 10^{-17} W

Thus the minimum number of photons is given by

N_{min}=P_{min}/E

where E = hc/\lambda

             = \left (6.63\times 10^{-34}\times 3\times 10^{8}  \right )/548\times 10^{-9}

            = 3.62\times 10^{-19} J

Therefore, N_{min} = \frac{2.8\times 10^{-17}}{3.62\times 10^{-19}}

                                              = 77.34 photons per second

Thus, the minimum number of photons per second is 77.34
