As microscope technology improved over time, the magnification became advanced enough to discover cells in the 17th century. Thi

s discovery is largely attributed to Robert Hooke, and began the scientific study of cells, also known as cell biology. Over a century later, debate continued among scientists about how cells began. Most of these debates involved the nature of cell reproduction, and the idea of cells as a fundamental unit of life. Cell theory was eventually formulated in 1839. The three tenets to the cell theory are as described below: 1. All living organisms are composed of one or more cells. 2. The cell is the basic unit of structure and organization in organisms. 3. Cells arise from pre-existing cells. How does cell division prove the cell theory? A) Cell division demonstrates spontaneous generation. B) Cell division demonstrates that cells come from preexisting cells. C) Cell division demonstrates that all living organisms are composed of one or more cells. D) Cell division demonstrates that the cell is the basic unit of structure and organization in organisms.

Answer:

The correct answer will be option-B.

Explanation:

Cell division is the process which divides a parent cell to daughter cells through sequential steps as a part of the cell cycle. The cell division takes place in two phases: Karyokinesis- the division of nuclear material and the cytokinesis- the division of the cytoplasm.

The cell division proves one aspect of the cell theory proposed by Rudolf Virchow that is cells arises from the pre-existing cells as the pre-existing cell divides to form the daughter cells through cell division.

Thus, Option-B is the correct answer.

Which is an effect of lower levels of solar radiation striking Earth?
ikadub [295]

Answer:

<u>B) decreased rates of photosynthesis</u>

Explanation:

Plants, phytoplankton, algae, and other microorganisms photosynthesize using energy in the form of solar radiation. Photosynthesis is a chemical process that's integral to these organisms, which are called producers.

They combine light energy from solar water and carbon dioxide, in a complex process that produces chemical energy in the form of glucose.

6CO_{2} + 6H_{2} O + light ---> C_{6}H_{12}O_{6}+6O_{2}

Photosynthesis is a rate-limited reaction; it depends on various factors including carbon dioxide availability and light intensity. When light is limited, the rate of photosynthesis decreases due to its slowing effect on the light-dependent reaction in photosynthesis, occurring in the chlorophyll.

Approximately ______ % of the world's sewage is discharged untreated into the world's rivers and oceans.
UkoKoshka [18]

Out of the following given choices;

15

7

24

95

The answer is 95%. The biggest contributors of this percentage are developing countries that do not have proper waste disposal  mechanisms such as well structured sewer systems.  It is estimated that 70% of industrial wastes in developing countries are disposed off untreated into waters where they end up in oceans through rain wash.
