1- C ( this is an assumption; a hypothesis is always based on an assumption.
2- F ( this states to share the results with other classmates).
3- D (this is a description of an experiment you could conduct; you test a hypothesis (usually) by conducting an experiment.
4- A (this is something you could observe during the experiment, therefore it is an observation).
5- E (this sentence is a conclusion).
6- B (This is an actual question)
Answer:
C. mode of internal temperature regulation
Answer:
The frequency of recessive allele should be 0.30.
Explanation:
According to Hardy-Weinberg equilibrium, sum of both dominant allele frequency (p) and recessive allele frequency (q) should be equal to 1 (p+q = 1).
Brown hair = dominant (p)
white hair = recessive (q)
49% mice are brown hair
so dominant genotype frequency = 0.49
According to Hardy-Weinberg principle, square root of the genotype (homozygous) is equal to allele frequency.
√p =√0.49 = 0.70
The dominant allele frequency is 0.7
Now, by this value we can find the recessive allele frequency by
p + q = 1
1 - 0.7 = 0.3
So, the recessive allele (white hair mice) frequency is 0.30.
Answer:
A transfer
Explanation:
Heat is the transfer of thermal energy from one object to another
57. Answer is d. less concentrated since water passes from B to A.
Osmosis is the movement of water molecules from a region of higher water concentration to a region of lower water concentration. So water will move from B to A, making it less concentrated solution.
An important part to notice here is that its the movement of water molecules (or any other solvent) through the membrane and not the particles dissolved in the water.
58. Answer is a. It will rise in side A since water (not the substance in it) will tend to pass from the area of greater concentration to the area of lesser concentration.
