Explanation;

  • The name of the general was Leslie Richard Groves Jr. He graduated from the United States Military Academy of West point in the year 1918.
  • As an engineering aide, He led a small team of workers who helped produce the exterior casing of "Fat Man," a nuclear bomb dropped on Nagasaki, Japan, that hastened the Japanese unconditional surrender three weeks later.

Leslie Richard Groves Jr. is the right answer.

He was the general who conducted the project accountable for the "Fat Man”. He became graduated in the year 1918, from the United States Military Academy of West Point. He directed as a small group of engineers who build the outer casing of "Fat Man," an atomic bomb released on Nagasaki, Japan, that urged the Japanese absolute submission in the next three weeks.

Which one of the following is a characteristic of a metal? A. Changes the color of litmus paper to red
B. Conducts heat readily
C. Reacts with bases to produce salts
D. Becomes negative when combined with other elements

Answers

B) Most metals conduct heat readily. In pure elemental forms, theyneither have basic or acidic properties. Other properties includemalleability, high melting points, high densities, and electricconduction.
the answer is B conducts heat rapidly 

In an exothermic reaction, the products have a _____ bond energy then the ______ .Overall ,energy is ______

Answers

In an exothermic reaction, the products overall have a higher bond enthalpy than the reactants. Overall, energy is given out of the system (because more energy is released forming the bonds in the products than is required to break the bonds in the reactants).

Energy in most ecosystems must flow through autotrophs because ______.a. only autotrophs can convert solar energy into chemical energy
b. autotrophs are simpler organisms than heterotrophs
c. heterotrophs only generate a small fraction of their energy from photosynthesis.
d. all of the above

Answers

Answer: Option A

Explanation:

Only autotrophs have the ability to convert solar energy into chemical energy by the process known as photosynthesis. The autotrophs can trap all the radiant energy and only 10% of total energy that autotrophs have is transferred to another tropic level.

The energy from the producers are transferred to the herbivores and 10% of the total energy the herbivores have is transferred to another levels.

So, the energy flow takes place through the autotrophs because only they have the ability to perform photosynthesis.
The right answer for the question that is being asked and shown above is that: "d. all of the above." Energy in most ecosystems must flow through autotrophs because  heterotrophs only generate a small fraction of their energy from photosynthesis; only autotrophs can convert solar energy into chemical energy; autotrophs are simpler organisms than heterotrophs
