Secondary succession is the series of community changes which take place on a previously colonized, but disturbed or damaged habitat. Secondary succession<span> is a much </span>more rapid<span>process than primary </span>succession<span> because the soil and nutrients are already available. Hope this helps.</span>

irakobra [83]

Answer:

Incomplete dominance is the inheritance pattern where the dominant allele did not mask the recessive allele completely and form a mix of both alleles. Here the inheritance is the incomplete inheritance. The ratio of F2 generation is 1:2:1.

Given:

R1R1 = 42

R2R2 = 39

R1R2 = 86

Total R1 alleles = 2*42+86 = 170

Total R2 alleles = 2*39+86 = 164

Total alleles = 334

Frequency of allele R1 = 170/334 = 0.51

Frequency of allele R2 = 164 / 334 = 0.49

Expected number of each phenotype:

Total population = 167

Blue = R1R1 = 0.51 * 0.51 * 167 = 43.44

Green = R2R2 = 0.49 * 0.49 * 167 = 40.10

Cyan = 2*R1*R2 = 2*0.51*0.49*167 = 83.46

Phenotype     Observed(O)    Expected (E)    O-E      (O-E)2     (O-E)2/E

Blue                 42                   43.44               -1.44       2.0736     0.0477

cyan                86                   83.46                 2.54     6.4516     0.0773

green              39                    40.1                    -1.1       1.2100      0.0302

Total              167                     167                                               0.1552

Chi-square value = 0.155

Degrees of freedom = no. of phenotypes – 1

Df = 3-1 = 2

Critical value = 5.99

Chi-square value of 0.155 is less than the critical value of 5.99. So we accept the null hypothesis.

The vestibular system is the only sensory system to send projection fibers directly to the cerebellum.
Greeley [361]

Answer: False

Explanation:

The above statement is false as, cerebellum receives the projection fibers from the other sensory system in which they are received in the different part of cerebellum. As, the cerebellum received the information from the sensory system and the spinal cords and also in the other part of the brain as it regulates in the movement of the motor.

What types of cells carry out photosynthesis?
Sedaia [141]

On the cellular level, the reactions for photosynthesis occur in organelles called chloroplasts (in eukaryotic cells). Blue-green algae (which are prokaryotic) carry-out the photosythesis reactions in the cytoplasm.

So all of the above
