</h2>
the Cell Theory was give by German scientists, Schleiden and T.Shwan in 1839. It stated that,
- All organism are composed of one or more cells
- The cell is the structural and functional unit of life
- It is a de novo structure, that means it COULD arise from non living thing which was incorrect.
It was corrected by the German pathologist Rudolf Virchow in 1855. He made a convincing case, corrected and added the third point of the cell theory. It is,
- Cells can arise only by a division of pre-existing cell. It is NOT a de novo structure.
Cell theory brought a great evolution in the field of biology which established the function of organism is the result of activities and interaction of the cell units.

The high specific heat capacity of water moderates our climate and allows for life on Earth.
Because it takes a great deal of heat to warm up water, water stays cool longer, and acts as an effective coolant. This is why cool "sea breezes" are welcome on a hot summer's day.
On the contrary, once the water is warmed up, it takes a great deal of heat release to cool the water. This keeps warm winds blowing in off large lakes and oceans in the fall and into the winter, making the temperatures not as frigid as they otherwise could be.
This also accounts for the amounts of precipitation that occur around large lakes, such as the Great Lakes, and oceans.
Explanation:
Crossing over is an important section of the normal segregation of the chromosomes in case of the meiosis. Crossing over happens due to the genetic variations, as the genetic materials gets alter at the time of crossing over. The chromatids that are bind together with the help of the centromere do not remain similar in this case. Crossing over gives rise to variation because the alternation takes place between the nonidentical chromatids having different characteristics or traits. Sometimes gives rise to completely new trait which is not present in both the parents this condition makes the . genetic diversity.
<u>Answer</u>:
Evolutionary process could cause several species to evolve into several hundred species
<u>Explanation</u>:
Being an evolutionary process, it gives rise to new species in more numbers. It is caused because of mutation upon a certain population for a long time. Various other mechanism can also lead to speciation. Another thing is also responsible for it that is genetic drift which leads to random ups and down in the population frequencies. That is helpful in evolution of several other species. Natural selection is also an factor for large evolution and species formation
Answer:
upper limb and mammary gland
Explanation:
The lymph nodes of the axillary region or the axillary lymph nodes drain lymph vessels from the breast, from thin walls of the chest and the upper part of abdomen , and from the upper limb. They can be divided in groups according to their location.
These lymph nodes has a role in development of breast cancer and its metastasis.
