Explanation:
it is the final process of oxidisation for food stuff
Answer:
The difference in lighting in this study is an independent variable.
Explanation:
In a scientific study or experiment, the variable being tested or measured or affected by the experiment is called the dependent variable. The independent variable is the variable that is not dependent on any other variables or factors. It is changed or controlled during an experiment in order to cause a change in the dependent variable.
Here, the study is conducted on rats to observe the impact of ginkgo biloba on rat's memory when a measured dose of the same is given through their diet. Ginkgo biloba helps to retain short-term spatial memory in rats. Rats are comfortable in the light and get used to any lighting situations. But they avoid light due to their nature and are generally nocturnal. They cannot see properly in the dark, but can easily navigate through the darkness with the help of their extremely sensible whiskers. The difference in lighting during the experiment acts as an independent variable that is manipulated to induce a change in the dependent variable, to check the ability of ginkgo biloba-enhanced rats and normal diet rats that run through a complicated maze.
Answer:
Anaphase I - 2n = 6
Metaphase I - 2n = 6
Anaphase II- n = 3
Metaphase II- 2n = 6
Explanation:
In a meiosis cell division there are two cycle of division Meiosis I and Meiosis II. The genetic material duplicates during the S phase of meiosis I and hence at metaphase I the number of chromosomes will be 2n i.e 6. The number of chromosomes in Anaphase I is equal to the number of chromosomes in metaphase I since the chromatids remain attached during the anaphase stage. During metaphase II, the cell separates and hence the number of chromosomes at this stage is equal to n i.e 3 while at anaphase II the number of chromosomes is equal to 6
Two stages that occur in the carbon cycle are: Animal respiration and emissions from factories
Animal respiration is carbon dioxide and water that is released into the atmosphere .
carbon emissions can be absorbed by plants and trees during photosynthesis to produce food.
2. Solar power is a sustainable way to gather energy as it does not harm the atmosphere and carbon emissions. However,sunlight may not always be available in winter months due to shorter days and longer nights. solar panels can also be very expensive to set up, but costs can be broken even over a period of years.
Nuclear power can be a cheap way to produce electricity as deposits of uranium and plutonium will last for the next couple of thousands of years (3000-4000 years). power plants can cost colossal amounts to set up but have relatively low running costs. please like and thank me that was a lot to write
