What did you include in your response? Medications can be tested on cell cultures instead of being injected into patients unnece

ssarily. Cancer cells continue to grow in the cultures uncontrollably allowing scientists to test multiple medications on the cancer cells. Specific treatments that are shown to fight the growth of cancer cells in the culture can be used on patients. Cultures are safer to use than injections of unneeded medications into patients.

Answer:

The statements are correct.

Explanation:  

Cell culture is a technique widely used in molecular biology where cell lines are grown in controlled conditions, thus allowing to make experiments and to test compounds that may result useful to treat diverse diseases, including cancer.  

Immortalized cell lines are characterized for their ability to proliferate indefinitely which are derived from oncogenic tissues. In cancer research, these lines are used as models to test different drugs and to study cellular mechanisms associated with cancer progression including, among others, proliferation, invasiveness, vascularization, etc. In addition, the mechanisms associated with the death of cancer cells such as, for instance, apoptosis, may also be studied by using immortalized lines.

How is the process of carbon fixation in CAM plants different from the process in C3 and C4 plants? a. CAM plants require a larg
Leya [2.2K]

Answer:

The correct answer would be option C.

Plants evolved different methods to prevent or reduce the effects of photorespiration.

The C3 plants are the most common plants which do not have any special methods or physiology to prevent photorespiration.

The C4 are the plants in which carbon fixation and the Calvin cycle takes place in different cells. Carbon is fixed in the mesophyll cells with the help of PEP carboxylase enzyme. It fixes carbon and converts PEP into oxaloacetate. The Calvin cycle takes place in the bundle-sheath cells.

In contrast, CAM (Crassulacean acid metabolism) plants are those in which carbon fixation and Calvin cycle are separated into time. The carbon is fixed during the night as it helps in reducing the loss of water through transpiration.

The Calvin cycle takes place during the day time in the same cell, that is, mesophyll cell.

what is accepted by scientists as evidence for evolution? I. Similarities in bone structure between the wings of a bat and the f
Mandarinka [93]

Answer:

Options I and II

Explanation:

Evolution refers to the changes that occurs in the morphology, appearance and behavior of an organism over a due course of time. This changes occurs due to the natural selection method, where organisms undergoes changes and adapts to the newly habitable environment.

The above given options I and II are the evidences of evolution. The similarities in terms of bones and their defined structure between the bat wings and porpoise fins are signs of evolution that has taken place over a definite span of time. Also, the changes in the various breeds of dog that are caused by the artificial selection method is also an example of evolution.

Thus, the correct answers are options I and II.
