Which process uses energy to combine inorganicmolecules to synthesize organic molecules?
(1) respiration (3) photosynthesis
(2) digestion (4) decomposition

Answers

The process which uses energy to combine inorganic molecules to synthesize organic molecules is referred to as(3) photosynthesis.
The chemical energy which is basically formed in carbohydrate molecules for each sugar and are being synthesized by water and carbon dioxide. Photosynthesis is also performed by most cyanobacteria and algae.
Some of this organisms are called photoautotroph. Photosynthesis is well known for maintaining and producing oxygen content of the earth's atmosphere. The process of photosynthesis begins when energy which is from light is being absorbed by proteins known as reaction centers and contain green chlorophyll pigments.
When in plants the proteins are being held inside the organelles known as chloroplasts and abundant in life cell.

What is the mechanical advantage of a machine that applies a force of 1000 N to an object when a force of 500 N is applied to the machine?

Answers

The mechanical advantage of the machine in the problem is 2. By definition, the mechanical advantage of a machine is equivalent to the ratio of its output force to its input force. Since it applies a force of 1000 N to an object, that is its output. Also, since a 500 N force is applied to the machine, that is its input. So 1000/500 = 2.

Answer: 2

Explanation:

The mechanical advantage of a machine is defined as the amplification of the force produced when using a machine or a tool.

In mathematical terms, it is the ratio of the output force to input force and, the formula is :

MA = Fo/Fi

Where MA= mechanical advantage

Fo= Output force

Fi = input force.

According to the question, Fo= 1000N

Fi= 500 N

Therefore, MA= 1000/500 = 2

Favorable changes in species get passed down through the generations because of

Answers

Answer:

Natural selection

Explanation:

Natural selection favors the individuals carrying the adaptive variations and allows them to reproduce more as their beneficial variations impart them the survival advantage. These individuals with beneficial adaptive traits reproduce more and produce a large number of progeny, all carrying the useful adaptive features of the parents.

Hence, natural selection favors individuals with beneficial variations. The differential rate of reproduction of the favored individuals allows inheritance of favored variations to the future generations.

That process is called natural selection

What typically happens to amino acids once they arrive in a cell?

Answers

primarily, amino acids are needed in a protein making process
