Correct answer: B). Food and fossil fuels
The energy can not be created nor destroyed but it can be transformed into another form. The ultimate source of energy on this planet is the sun, the sun provides sunlight where sunlight is converted into chemical energy, which is used by plants to prepare food. Then we consume food prepared by plants to get energy and perform various types of work like movement, reproduction, growth etc. In this, the chemical energy is converted into mechanical energy.
The number of protons in the atom can be used to determine the element
Nitrogen is so vital because it is a major component of chlorophyll
And it also is a major component of amino acids, the building blocks of proteins. Without proteins, plants wither and die.
Answer: The basic cell division in plant and animal cells are similar but there are still some differences.
The similarities between onion root and whitefish cell In mitosis cell division is that the four phase of mitosis I.e anaphase, prophase, metaphase and telophase occur the same way.
In prophase, the chromatins are condensed, in
Metaphase the chromosomes adjust and move to the center, in anaphase, the chromatics from metaphase are separated and move to the opposite poles. At Telophase, the cells divide through cytokinesis.
Their major differences is in cytokinesis stage.
The onion cells divide along the same axis but the white cells division is random.
Explanation:
The epidermal cell of onion give its protection against vacteria, viruses and fungi.
The white fish embryo is good to study mitosis because its cells are randomly dividing.
