Answer:
This question lacks options, the options are:
A) Light-capturing pigment molecules in green plants absorb red, blue and violet light but reflect green light.
B) The energy of a photon of light is proportional to its frequency and inversely proportional to its wavelength
C) As light energy is converted to chemical energy by metabolic processes, some of the energy is lost as heat
D) Captured energy is stored in the molecular bonds of organic molecules, including simple sugars and starch
The answer is:
As light energy is converted to chemical energy by metabolic processes, some of the energy is lost as heat.
Explanation:
Green plants are capable of synthesizing their own food via a process called photosynthesis. The photosynthetic process uses light energy from the sun to form organic chemicals necessary for the growth and repair of plant tissues.
Plants are able to capture light energy from the sun using their chlorophyll pigment. Out of this captured energy, only a portion of the light energy captured by green plants is available for growth and repair. This is because as light energy is converted to chemical energy (stored in chemical bonds) by metabolic processes, some of the energy is lost as heat.
Answer:
Option (1).
Explanation:
The RNA is produced from the DNA by the process known as translation. The proteins products are produced from the RNA by the process known as translation. Proteins are the polymers of the amino acids.
The situation 1, radioactive amino acids has been used. In this case, the mRNA is used in this process to make the radioactive proteins by the process of translation. The radioactive amino acids are used for the formation of radioactive protein. The situation 2, the RNAase has used with radioactive amino acids. In this case, the RNAse enzyme breaks the mRNA molecule and the proteins are not translated that contains the radioactive amino acids. No proteins formation occurs in this case.
Thus, the correct answer is option (1).
Particles or molecules that are too big to fit through regular pores in the cell membrane, or have to big an electric charge, against the current of passive transport ( lower to higher ).
Answer:
Fiber helps to prevent <em>constipation </em>in the human digestive system.
Explanation:
According to nutritionists fiber is very important in digestion as it increases the amount of stool , hence prompting for deification which generally reduces the amount of time waste stays in the small intestines .
Another reason is that it gets in touch with the schist that has been rejected or is of no value to the system and binds it to make it compact waste hence it is easier to move along the small intestine and the colon .
Finally it facilitates movement and exercise of the bowel , by prompting regular movement .
Impact of the use of fossil fuels during the industrial revolution was it made possible a huge increase in the amount of productive energy available to humans.
The development of machines, including steam engines and the internal combustion engine, made it possible to exploit vast new resources of energy stored in fossil fuels, specifically coal and oil. The fossil fuels revolution greatly increased the energy available to human societies during industrial revolution.
Contrary to this fossil fuel have some disadvantages like when fossil fuels are burned, they release large amounts of carbon dioxide, a greenhouse gas, into the air. Greenhouse gases trap heat in our atmosphere, causing global warming.
