He must include A. Ribosomes, B. Endoplasmic reticulum and C. Golgi apparatus organelles in the model.
The ribosomes are organelles that are responsible for protein translation and are composed of rRNA and proteins. The rough endoplasmic recticulum synthesizes the protiens and the Golgi apparatus collects and dispatches protein products received from the endoplasmic reticulum. Proteins synthesized in the endoplasmic recticulum are transported into vesicles, which then fuse with the Golgi apparatus and further transported to their destination.
Unregulated and uncontrolled cell growth is the most common simple definition of cancer. Because of the many types of cancers and a huge range of possible symptoms, treatments are also very diverse. Type of treatment also depends on cancer stage at diagnosis, and the patient's overall health. Some forms of treatment:
• Chemotherapy-usage of chemicals (medications) that target rapidly uncontrolled dividing cells,
• Hormone therapy
• Immunotherapy-usage of the medications that boost the immune system
• Radiation therapy-usage of radiation to kill the cancer cells
• Surgery
• New approaches such as stem cell therapy or personalized therapy.
Answer:
No because the tectonic plate theory says that they move but if they didn’t move then it proves it wrong.
The basics would be that you'd need to find out if they could exchange genetic information. If not, they couldn't be considered part of one species. Set-up 2 artificial environments so both groups would produce pollen at the same time. Fertilise both plants with the other's pollen. Then fertilise the plants with pollen from their own group.
Count the number of offspring each plant produces.
If the plants which were fertilised by the opposite group produce offspring, they are of the same species. You can then take this further if they are of the same species by analysing if there is any difference between the number (and health) of offspring produced by the crossed progeny and by the pure progeny. You'd have to take into account that some of them would want to grow at different times, so a study of the progeny from their first sprout until death (whilst emulating the seasons in your ideal controlled environment). Their success could then be compared to that of the pure-bred individuals.
Make sure to repeat this a few times, or have a number of plants to make sure your results are accurate.
Or if you couldn't do the controlled environment thing, just keep some pollen one year and use it to fertilise the other group.
I'd also put a hypothesis in there somewhere too.
The independent variable would be the number of plants pollinated. The dependant variable would be the number of progeny (offspring) produced.
Answer:
C. a decrease in phospholipid fatty acid side chain length and a decrease in side chain saturation
Explanation:
Temperature is a factor that has a huge impact on cell membrane structure, more precisely its fluidity. So, for example, if temperature increases, the cell membrane becomes more fluid because the fatty acid tails of the phospholipids become less rigid.
