Yes!
A tree has plant cells and has a plasma membrane and a cell wall. It also has chloroplasts that contain chlorophyll!
sunlight, as chloroplasts in the leaves soak up the sunlight and use it as a way to respite.
1 AU means 1 astronomical unit or the aproximate distance from the earth to the sun
1AU=<span>149597870.7 kiometers
1 billion=1,000,000,000
600 billion=600,000,000,000
</span>
<span>x times 1AU=600,000,000,000
x times </span>149597870.7=<span>600,000,000,000
solve for x
divide both sides by </span><span>149597870.7
</span>x=4010.75
so aprox 4011 AU's
Answer: There is presence of tumor.
Explanation: The adhesion of cells to extracellular matrix (EMC) through integrins ( cell-EMC binding molecules, which are collagens, laminins and fibronectin) causes the activation of kinases in the cytoplasm.
However, kinanes helps in controlling the epithelial cell differentiation and upholding the epithelial tissues. This is done by the addition of phosphate groups to a substrate protein which is termed Protein phosporylation. Then, the kinases direct the affairs of the cell and it's activities. For example, it determines the cell division, anabolic and catabolic activities of the cell, movement of ions between the cell and it's environment (signal transduction), protein functions and etc.
Conclusively, since the activities of the cell like cell division and protein functions is dictated by the kinase, reduction in cell division that gave rise to rapid growth is put on hold. Hence, the tumor is been suppressed.
Note: the binding of cell-EMC is regulated by Transforming Growth Factor (TGF) β.
The correct order is: B) 2, 5, 4, 3, 1.
2. A segment of DNA is transcribed in mRNA. mRNA is transferred to the cytoplasm. This is the process of transcription that occurs in the nucleus of the cell and it is the first step of gene expression. It is performed by the enzyme RNA polymerase.
5. The mRNA strand is fed through the ribosome. Ribosome is an organelle where protein synthesis (translation) occurs and it consists of proteins and RNAs.
4. Molecule of tRNA delivers amino acids from to the ribosome. tRNA is transfer RNA because of its function to carry amino acids to the ribosomes during protein synthesis.
3.The amino acids are dropped off at the ribosome.
1. The amino acids are joined to make a protein. Amino acids are added to a growing protein chain.
