The correct option is A.
An exponential growth is a type of growth whose rate becomes more rapid in relation to the total number that is available. When a specie has newly been introduced into a new area, they usually give birth rapidly and take over their new environment. If you check the options given above, you will see that it is only option A that have numbers that continuously increase. An exponential growth increase continuously. <span />
The science of Cancer Biology focuses on the study of the different mechanisms and fundamental process of cell growth, the transformation of normal to cancer cells, and the metastasis or spread of these cancer cells to other parts of the body.
As such, it includes the study of how tumor cells develop and grow. It also includes studying how the immune system responds to cancer cells, thus including macrophages and their response to the presence of pathogens and cancer cells. Underlying all these is the inclusion of a study on protein synthesis as it is the process where biological cells build and create new specific proteins in the body.
The fundamental building blocks of life are cells. No matter how large or little, straightforward or complex, the cell hypothesis holds true for all living things. Cells are believed to be a component of all living things, hence they can reveal information about all life.
Schleiden and Schwann advocated spontaneous generation (also known as abiogenesis) as the mechanism for cell origination, but spontaneous generation was later demonstrated to be false. The famous phrase "Omnis cellula e cellula" by Rudolf Virchow "Only pre-existing cells can give rise to new ones." However, the portions of the hypothesis unrelated to how cells first formed withstood scientific investigation and are currently accepted by the majority of scientists. The following are the elements of contemporary cell theory that are commonly acknowledged:
The basic unit of structure and function in living things is the cell.
One or more cells make up every living thing.
Through cellular division, new cells are created from existing ones.

Answer:
The question lacks options, the options are;
A) 4 KJ
B) 122 KJ
C) 30.5 KJ
D) 1600 KJ
The answer is B, 122KJ
Explanation:
Adenosine triphosphate (ATP) is the energy currency of all living cells. It is the usable form of energy by cells for their life functions. Energy in ATP is harnessed via the hydrolysis of one of its phosphate molecules to form Adenosine diphosphate (ADP). The energy (measured in Kilojoules) needed by cells is released in this process.
In this case, a cell uses energy to pump hormones into the bloodstream. According to the question, 4 ATP's were used i.e. 4 ATP were converted to ADP. The hydrolysis of one ATP molecule releases 30.5 KJ/mol of energy needed for cellular work.
Hence, if 4 ATP were utilized by this particular cell, 4 × 30.5 KJ = 122 KJ of energy will be used by the cell to pump hormones.
