The small water born plants or animals are known as plankton. They can be either phytoplankton or zooplankton.
The relationship between the the distribution of coral polyps and the population density of plankton is that coral polyp depends on the plankton for their nutrition.
Most of the coral polyps like zoanthids depends on phytoplankton and zooplankton for their food(nutritional needs).
They also depend on the bacterioplankton for their food.
to repeat to reduce the amount of data that must be recorded.
because this is necessary for graphing the data.
because this is necessary for the data to be valid.
Answer;
Because this is necessary for the data to be valid
-The most important reason to control the conditions of an experiment is because this is necessary for the data to be valid.
Explanation;
-In a controlled experiment, the group that is testing the independent variable is called the experimental group. The other group that does not tests this variable is called the control group.
-It is important to make sure that when conducting a controlled experiment to test an hypothesis , all the variables are the same in two test groups apart from the case of independent variable.
B. Cerebrum
C. Spinal cord
D. Hypothalamus
C spinal cord on Edge took the quiz
b. resulting in variationasexual reproduction in the plants
c. resulting in variationgenes being expressed in different ways due to environmental conditions
d. a gene mutation that occurred after the clone was produced
Answer:
Option C, resulting in variation genes being expressed in different ways due to environmental conditions
Explanation:
Several genetic traits are affected by both internal and external environmental conditions. Some common examples are – height , color of eye, hair color, skin color, and even some genetic diseases.
The internal environmental factors include – gender, temperature etc.
While the external environmental factors include drugs, chemicals, temperature, and light.
Hence, the external environmental condition i.e pH of soil is producing different color of flowers in a given plant
Hence, option C is correct
DNA contains the code for constructing the protein molecules in a cell of an organism. Thus, the correct option is A.
DNA stands for deoxyribonucleic acid. DNA is a polymer which is composed of two strands or chains of polynucleotide chains which coil around each other to form a structure called as double helix.
The nucleic acid polymer carries the genetic instructions for the development, functioning, growth and reproduction of all the known living organisms and many of the viruses. DNA and RNA are nucleic acids. DNA contains the cods for the construction of protein molecules.
Therefore, the correct option is A.
