It should be A if im not mistaken
Answer:
Explanation:
Blue-white screening is a method for distinguishing proof of (recombinant bacteria). It depends on the capacity of ( B-galactosidase) to separate lactose. Blue-white tests exploit the molecule called (x-gel)_ which is like lactose in that it is severed by B-galactosidase. When separated, the (5-bromo-4-chloro-indoxyl) (same as past) turns _(_blue). In the event that uncleaved, which implies a non-function B-gal gene, the X-gal remains (white)_. Subsequently, a __(white) bacterial province implies the B-galactosidase gene isn't practical, and in this way there ___lacz__ a recombinant gene embedded into the vector.
Cells build carbohydrate polymers by using energy to form glycosidic linkages, the bonds betweenmonosaccharides. A dehydration synthesis reaction forms a bondbetween carbon atoms in twomonosaccharides, sandwiching an oxygen atom between them and releasing a water molecule.
A cell membrane is not rigid like the cell wall. The cell wall gives structure and shape to the cells. Cell wall are only found in plants. They both keep their organelles inside the cell
Answer: Malignant tumor-
cancer cells are contained within their tissue.
Maglinant tumor-- Cells of this type of tumors have the potential to , escaping their tissue and spreading to other locations within the body.
Benign tumour-pre-cancerous cells highly disorganized metastasize.
Explanation: Tumor is an abnormal growth in the cell.
Benign tumor is a tumor that do not spread within the cell and are not cancerous. The can grow to very large and are removed by operation. It can be very dangerous when its big and press other tissues especially when located in the brain. It may not require any treatment when it is not threatening. Example of benign is fibroid
Malignant tumour are tumour that are cancerous and can spread to other tissues. They can be transported via the blood stream to other tissues. Malignant tumour grows fast and can spread to nearby tissues example is breast cancer when not diagonize earlier can spread to other tissues. They required medical attention and can be removed through operation, some require chemotheraphy. Some malignant tumour grows back even after removal.
