Euglena are like all other cells because they<span> grow and reproduce. They obtain nutrients by taking in other microorganisms an make their own food by using the energy from sunlight.</span>
A good topic idea that could be used can be about ecosystems. Such as how geographic area, plants, animals, weather and landscape make up the types of organisms in that specific ecosystem.
Answer: 20%
Explanation:
Recall that the sum of all nitrogenous bases is equal to 100%.
Hence: A + C + G + T = 100%
Now, since adenine nucleotides is 30%, then thymine is 30% as well (A = T). Thus, the total of both is 60%.
From 100 remains 40% which is divided equally between guanine and cytosine, so each is 20%.
Thus, the percentage of the same DNA molecule that would be expected to be guanine nucleotides is 20%
Increased in pitch (frequency). It's the doppler effect.
4. Large, circular lily pads are able to float on the water's surface.
Answer: cohesion
Cohesion mean that water attracted to another water. This force will make the water to form a surface tension in the lake. Water lily has a wide and thin leaf which makes it giving a low force per area. If the force applied on the surface is not bigger than surface tension, the leaf will stay float above the water. Surface tension also the reason water spider could walk on water.
5. The temperature of the water is about 5°C, while the temperature of the air is about 21°C.
Answer: heat capacity
Water has high heat capacity. High heat capacity mean that the water will not be easily become cold or hot. It will need more energy to increase/decrease the temperature of the water. This is why the water could keep its temperature much lower than the atmosphere. This will protect the organism inside the water from an extreme temperature change.
