Since plasma cells make your antibodies, they need to produce a lot of protein. Also because the nucleus makes a lot of products to make proteins you need a large Golgi Body. How ER's relate to this: to do protein synthesis you need ribosomes and to have ribosomes you need the rough ER!
Answer:
This question is incomplete, it is asking to identify the following variables in the question:
Independent Variable: DIFFERENT AMOUNTS OF OIL
Dependent Variables: NUMBER OF KERNELS THAT POPPED
Controlled Variables: TIME FOR POPPING, SAME BRAND OF KERNEL, SAME COOKING TIME
Explanation:
The independent variable of an experiment refers to the variable that the experimenter intentionally manipulates or changes for the purpose of effecting a measurable response in another variable (dependent variable). In this experiment, the independent variable is DIFFERENT AMOUNTS OF OIL used because this is what Jason changes in the experiment.
Contrarily, the dependent variable is the variable that the experimenter measures in response to the independent variable. In this experiment, Jason measures the NUMBER OF KERNELS THAT POPPED from using different amounts of oil. Hence, the NUMBER OF KERNELS THAT POPPED is the dependent variable.
Controlled variables or constants are those variables that must be kept constant or unchanged throughout the experiment in order not to influence the findings of the experiment. In this case, the following variables were kept constant for all the groups: TIME FOR POPPING , SAME BRAND OF KERNEL (Pop rite), SAME COOKING TIME (4 mins).
Answer:
Algae produces food and catfish also needs warm water.
Explanation:
Sunlight regulates the productivity of algae and the number of catfish in a pool because algae produces food in the presence of sunlight during the process of photosynthesis. If algae produces more food, so more food is available for the catfish and as a result the population of catfish increases. If no sunlight occur on the pool the algae is unable to produce food and the population of catfish decreases. Sunlight increases the temperature of water which makes environment suitable for the catfish because catfish needs slightly warm water for its growth. So we can say that sunlight has a great affect on algae and catfish.
The higher the GC content of a DNA, the higher the strength of the interchain interactions, and the higher the melting temperature.
DNA is Deoxyribonucleic Acid. It is the genetic material in maximum of the organisms. The DNA is a polymer made from nucleotides (sugar, nitrogenous bases and phosphate group). It is composed of two strands of phosphate and sugar backbone in an antiparallel direction. The nitrogenous bases present in DNA are Adenine (A), Thymine (T), Guanine (G) and Cytosine (C).
GC content refers to the total amount of Guanine and Cytosine present in the DNA. Since there exists a triple bond between G and C, more percentage of them provides strength to DNA. That is why high GC content denotes high melting temperature of DNA.
