Some of the reasons of for the sudden development of cell theory after a long break are:

As at the time Robert Hooke and Anton Van Leeuwenhoek made their discoveries about cell, both of them and other scientists of that time do not have access to great sophisticated instrument which could aid their research. Their inability to have access to technological innovations do not make them go far.

It is not surprising that Theodor Schwann, Mathias Schleiden and Rudolf Von Virchow made their breakthrough within a short period of time simply because of the use of improvement of technological innovations with which they use to invent the cell theory.

C) it changes electrical energy into light energy plus heat

Explanation:

Explanation:

Mitosis and endocytosis are two fundamental cellular processes essential for maintaining a eukaryotic life. Mitosis partitions duplicated chromatin enveloped in the nuclear membrane into two new cells, whereas endocytosis takes in extracellular substances through membrane invagination. These two processes are spatiotemporally separated and seemingly unrelated. However, recent studies have uncovered that endocytic proteins have moonlighting functions in mitosis, and mitotic complexes manifest additional roles in endocytosis. In this review, we summarize important proteins or protein complexes that participate in both processes, compare their mechanism of action, and discuss the rationale behind this multifunctionality. We also speculate on the possible origin of the functional reciprocity from an evolutionary perspective.

The number of white blood cells present in the body of a 140-lb person is 2.646 x 10¹¹.

White blood cells are also present in the body. They work for the immune system of the body.  

First, calculate the microliters of blood there are in a 140lb person.

140 x (2.7 x 10⁴)

140 x (2.7 x 10 x 10 x 10 x 10)

140 x 27,000

3,780,000 of microliters of blood in a 140lb person

Then, the white blood cells in a 140lb person

3,780,000 x (7 x 10⁴)

3,780,000 x (7 x 10x 10 x 10 x 10)

3,780,000 x (70,000)

264,600,000,000 white blood cells in a 140lb person
