Answer:
Its D- Weather is a highly complicated system that is very difficult to predict.
Explanation:
Weather has a pattern so A is not the answer and no way Meteorologists would keep information to themselves so not B and lastly it's not impossible but just very hard so C is out, which leaves D.
Answer: B. Earth's present-day species evolved from older, identical species.
The evolution is the change or modification in the characteristics of a species over genration due to the process of adaptation and natural selection. The statement "Earth's present day species evolved from older, identical species is true about evolution". As, proposed by Darwin evolution is "descent with modification", which means that in a process of evolution species change and give rise to new species over generation. He proposed that newly evolved life forms can be traced back to their common ancestor.
Answer:
15. D have specific gened activated
16. G cell division is unregulated
17. D providing information to form proteins
Explanation:
15. When an egg is first fertilised, the cells are very flexible. They are sort of like a "blank slate", and can become any type of cell. From these cells, all the cells in the body are created: brain cells, skin cells, blood cells etc. To become all these different types of cells, they keep dividing, slowly branching off and becoming more specific. This process is called differentiation.
They do this because different patterns and combinations genes are activated that turn them in to these different and specific cell types.
16. One of the hallmarks of a cancer cell is unregulated cell division. Oncogenes start as normal genes (called proto-oncogenes) that function in normal processes, such as the cell cycle, inhibiting apoptosis. However, when they become mutated, they can promote the growth and division of cells and prevent their programmed death. This is because they become more active or present in higher amounts following the mutation. This causes such functions in the cell to become deregulated, leading to uncontrolled cell proliferation and the growth of harmful tumour cells.
17. The central dogma of biology states that DNA --> RNA --> protein. The messenger RNA (mRNA) is transcribed from the DNA. It contains a message that is translated by the protein synthesis machinery to form proteins.
This is how all the proteins in the cell are produced, and the information for how to encode them is entirely dependent upon the sequence of the DNA, which is sent as a coded message in the form of RNA, to the protein synthesis machinery. The protein synthesis machinery makes the proteins according to the DNA sequence (as translated from the mRNA).
Answer:
I think the "your masticular (jaw) bone to your skull."
Explanation:
"Examples include the fibrous joints of the skull sutures and the cartilaginous epiphyseal plate. A joint that allows for limited movement is amphiarthrosis. An example is the pubic symphysis of the pelvis, the cartilaginous joint that strongly unites the right and left hip bones of the pelvis."
Put simply, an amphiarthroses joint is a joint with more limited movement.
your wrist to your fingers - very movable
your cranium to your spine. - pretty moveable
So that is why I think it is your masticular (jaw) bone to your skull! Hopefully this is correct and helps, have a nice day! :D
