In 1907, Dr. Duncan MacDougall performed a series of experiments in which he attempted to measure the weight of the soul as it left a dying person. In his experiments, MacDougall placed a dying person on a scale and measured their weight immediately prior to and following death. MacDougall determined the change in weight to be approximately 21 grams. From these experiments, he concluded that the soul exists and has mass. What is the fundamental scientific flaw in his conclusions? (5 points)

The track star runs 100m at a rate of 10.4m/s. How long did it take to run 100m?
Answer:
Time, t = 9.62 secs.
Explanation:
Speed can be defined as distance covered per unit time. Speed is a scalar quantity and as such it has magnitude but no direction.
Mathematically, speed is given by the equation;
[tex]Speed = \frac{distance}{time}[/tex] ....equation 1
Making time the subject formula;
[tex]Time = \frac{distance}{speed}[/tex] .....equation 2
Given the following data;
Distance = 100m
Speed = 10.4m/s
Substituting into equation 2;
[tex]Time = \frac{100}{10.4}[/tex]
Time, t = 9.62 secs.
Which ion builds up inside the membranes of the chloroplast?
Answer:

Multicellular fungi share some key traits, including their body structures, growth patterns, and methods for absorbing nutrients. however, although their feeding methods may be similar, fungal species differ markedly in their sources of nutrients, which include both living and dead organisms. as a result, fungi play a variety of roles in ecological communities.
Explanation:
The structure of multicellular fungi is formed by filaments called hyphae, and the set of hyphae is called mycelium. Hyphae are made up of the substance chitin.
They can be of two types: vegetative or reproductive. In vegetative multicellular fungi, hyphae are found inside the substrate to remove the food.
And in the case of reproductive multicellular fungi, there is the formation of spores, which will form the fruiting body for reproduction.
what happens to the 90% of energy available if 10% moves on to the next trophic level
Answer:
Released as heat
Explanation:
The vast majority of energy in the ecosystem is used by the organisms to power chemical reactions in the cell.
Therefore, this energy is lost as heat when it powers metabolic processes, rather than being passed on to the next trophic level.
