Polyploidy (more than two complete sets of chromosomes) is not rare among plants. For example, pollen grains may reach female flowers via animals or wind. In some cases, pollen grains from species with 4 complete sets of chromosomes will have 2 sets of chromosomes. Pollen grains may fuse with a female reproductive organ with 1 set of chromosome (so, female plant must have 2 sets of chromosomes). The resulting zygote will have 2 + 1 sets of chromosomes, so the plant will have 3 complete sets of chromosomes.
True the ribosome does read the codons
<span>It is true that pritikin diet is often associated with
considerable reduction of blood cholesterol levels could lower heart problems. Pritikin
diet is low in fat, salt and high in fiber or unprocessed whole foods like
fruits, vegetables, low-fat dairy, fish, legumes, and lean proteins. Cardiovascular
exercises or daily walking is encourage to augment the effect of this diet.</span>
Answer:
1. IV: Time the Bell is rang DV: Time it takes to learn the task
2. IV: Nitrogen fertilizers DV: Diversity of fish
3. IV: Time of radiation DV: Percentage of successful germination
Explanation:
The independent variable of an experiment refers to the variable that the experimenter manipulates or changes in order to effect a measurable response in the dependent variable while the dependent variable is the variable that responds to the changes made to the independent variable.
1. In scenario 1, the TIME THE BELL RINGS is the independent variable because that is what the experimenter controls or has power to change. On the other hand, the dependent variable is the TIME IT TAKES TO LEARN THE TASK because it is the measured variable that responds to the independent variable.
2. In scenario 2, the USE OF NITROGEN FERTILIZER is the independent variable while the DIVERSITY OF FISH is the dependent variable.
3. In case 3, the TIME OF RADIATION is the independent variable while the PERCENTAGE OF SUCCESSFUL GERMINATION is the dependent variable.
Answer:
<em>Helloo!!! :D</em>
Explanation:
Full Question: The membranes of both B cells and the cancer cells are largely composed of phospholipids. Explain how, when the membranes are fused, the polar parts of the phospholipids from one cell will interact with the phospholipids from the other cell and how the nonpolar parts of the phospholipids from one cell will interact with the phospholipids from the other cell.
