Answer:
Cell growth but also involved in cancer development
Explanation:
Tyrosine-kinase receptors are the main receptors for the growth hormones, but also cytokines and hormones. These receptors are regulators of normal cellular processes, but if a mutation occurs it can lead to activation of a series of signalling cascades that change the gene expression. Consequently, this has a critical role in the development and progression of many types of cancer.
1) 75% purple flowered and 25% white flowered. If you complete the punnett square, you'll see the combinations are PP, Pp, Pp, and pp. The capital P is dominant (purple), so you know that 3/4 combinations will be purple flowers.
2) 50%. There is a 50% chance Grace will have Huntington's disease because since the disease is dominant, it is capital letter H. When you make a punnett square, you'll see the combinations are Hh, Hh, hh, and hh. There is a 50% chance Grace will have the Hh combination.
3) Protein. Protein is the only bio-molecule out of the 4 options, and the diagram shows a protein being made.
4) Transcription. Transcription is when the genetic message from DNA is transcripted onto mRNA.
A student wants to prove that amphibians appeared on earth before birds. The student should use the fossil findings as evidence to provide the most reliable information about the periods when amphibians and birds appeared on earth. Fossils would throw light on the internal body structures that bear the closest similarity to either the amphibians or the birds. The radiocarbon dating of the fossils will reveal its age. This can be used to figure out the time of divergence of the two types.
Answer:
Mass is conserved in living systems through the processes of photosynthesis, cellular respiration, and the carbon cycle. It is demonstrated in cellular respiration through the process of braking down food to provide energy and releasing carbon dioxide.
