Answer:
Plants require many materials name them and how r they obtained?
Plants require so many materials for growth which include nutrient, carbondioxide, adequate temperature, moderate pH, water e.t.c
Explanation:
Answer:
There are four things that are required: variation, inheritance, selection, and time. Variations are differences that exist among individuals.
Answer:
because it helps them live reproduce and grow thats all I really know if its not what you want sorry.
Answer:
1. Designing of the target vector.
2. Insertion of the target vector into the embryonic stem cell
3. Selection of the cells
4. Injecting selected cells into the new cells
5. Breeding of mouse with a normal mouse
Explanation:
The target vectors are made by inserting markers into them. The target vector is inserted into ES cells. The vector generally recombined with the target gene and knock-out that gene. Sometimes, recombination of vectors occurs at incorrect place.
The cells survive in the presence of markers only if the target gene is incorporated with target vector. The cells with the target vector are injected into a normal developing embryo of mouse.
The developed mouse will consist of heterozygous knockout cells and its own cells. The normal mouse is bred with this chimeric mouse. The offspring of these mouse are able to transfer knock-out gene to next generation.
Third-level consumers, or tertiary consumers, are carnivores who eat primary and secondary consumers. This almost NEVER happens, but there is sometimes a level higher than the tertiary consumers that eats them. It rarely happens, so often the tertiary consumers do not get eaten. Also, as tertiary consumers eat the primary and secondary consumers, they receive 10% of their energy from the producers. What happens with that 90%? Well, the 90%, most of the time, is lost to the environment as heat. Anyway, there more tertiary consumers besides the red fox, like the eagle, for instance, but there aren't many of the tertiary consumers because there isn't enough energy to get to them, since only 10% is being transferred each time a predator eats a prey in the food chain.
