How is a primary succession different from secondary succession?​

Biology

lorasvet [3.4K]3 years ago
8 0

Answer:

Primary succession is the change in a community over a long period of time when secondary succession is the change in a community over a short period of time.

Explanation:

primary succession clues- occurs in completely destroyed places like a glacier that has melted, has pioneer species, and has a climax community

secondary succession clues- occurs in abonded places like an abandoned park, does not require pioneer species

In flies dumpy wings and ebony bodies are each mutations recessive to wild type, and you expect them to behave in a Mendelian fa
Dimas [21]

Answer:

See the answers below

Explanation:

Assuming that D (d) represents the allele for wing type and E (e) represents the allele for body type, crossing DdEe with DdEe will yield the following offspring according to the Punnet's square (see the attached image):

(a) <em>9/16 D_E_  wild type </em>

<em>     3/16 D_ee  wild wing, ebony body</em>

<em>     3/16 ddE_ dumpy wing, wild body</em>

<em>     1/16 ddee dumpy wing, ebony body</em>

(b) Chi square X^2 = \frac{(O - E)^2}{E}, where O = observed frequency and E = expected frequency.

Phenotype                O                  E                                           X^2

Wild type                 473          9/16 x 830 =  466.875     \frac{(473 - 466.875)^2}{466.875} = 0.08

wild w/ebony b      156          3/16 x 830 = 155.625       \frac{(156 - 155.625)^2}{155.625} =  0.0009

Dumpy w/wild b     149          3/16 x 830 = 155.625      \frac{(149 - 155.625)^2}{155.625} = 0.28

dumpy w/ebony b  52            1/16 x 830 = 51.875        \frac{(52 - 51.875)^2}{51.875} = 0.0003

Total X^2 = 0.3612

Degree of freedom = 4 - 1 = 3

Tabulated value of X^2 (0.05)= 7.815

(c) <em>Since the calculated Chi square value is less than the tabulated value, we conclude that the observed outcome agrees with the expected outcome and that the cross followed the standard Mendelian pattern.</em>

Alenkinab [10]

Asymptomatic bacteruria is when there are elevated bacteria levels in urinalysis or there is culture growth but there are no symptoms thereby asymptomatic. Although asymptomatic, asymptomatic bacteruria is a form of urinary tract infections but only needs to be treated if the urinary tract infection is symptomatic or complicated such that in pregnancy, those with unstable comorbidities such as diabetes, and those with structural anatomic urinary tract defect i.e. vesicoureteral reflux. 


The correct answers are:

(1) Physical findings are absent; (2) asymptomatic; (2) if no symptoms present, no antibiotics recommended; (4) elevated bacteria level in urinalysis and culture
