Answer:amplitude,wave length, and frequency
Explanation:
Answer:
the formation of new and distinct species in the course of evolution.
Answer:
~ Three types of lipid are found in biological membranes, namely phospholipids, glycolipids and sterols.
Explanation:
~ Phospholipids consist of two fatty acid chains linked to glycerol and a phosphate group. Phospholipids containing glycerol are referred to as glycerophospholipids
Although tube worms cannot produce their own food, they often thrive around these underwater vents. They are able to survive because inside the tube is the trophosome, an organ that contains millions of bacteria in symbiotic relationship with the worm, which are responsible for feeding these creatures that do not have any type of digestive system or visual organs, as they live in the most absolute darkness.
Answer:
A) Identify the Dependent and Independent variables
The Independent variable is Temperature.
The Dependent variable is the seeds. The dependent variable is the variable that is being studied.
B) Calculate the average height of the seedlings in tube C.
To find the average, you must add up all of the heights and divide by the number of seedlings.
3.4 + 4.5 + 2.5 + 3.7 + 2.8 + 4.4 + 4.3 + 2.9 + 2.1 + 3.7 = 34.3
34.3 ÷ 10 = 3.43 cm
C) Conclusion
The seedlings in tube C grew much taller than the seedlings in tubes A and B.
This means that seedlings germinate better in warmer temperatures.
D) Why does Temperature affect Germination?
The temperature of the climate affects the dampness of the cotton wool. Moisture is key to germinating seeds. Seeds like a moist but not soggy environment caused by the correct temperature.
E) How could the experiment be better controlled?
The light levels in this experiment varied, but were not accounted for in the calculations.
It would have been better to keep them all under the same amount of light in order to keep the experiment accurate.
