Elodia [21]

The answer is tropical savanna. The region’s ecosystem is characterized by tall grasses, shrubs, and a scattered distribution of trees (especially acacia trees). Large regions of tropical savanna extend through the nations of Botswana, Namibia, and Kenya in Africa. Savannas are also characterized by seasonal water availability, with the majority of rainfall confined to one season. They are frequently found in transitional zones between forest and desert or grassland.

7. In some chickens, the gene for feather color is controlled by codominance. The allele for black is B and the allele for white
kondor19780726 [428]

Answer:

See the answer below

Explanation:

<em>Genotype is the genetic composition of organisms and a gene is made up of two alleles.</em>

a) Since the allele for black is B, <u>the genotype for black chickens would be BB. </u>

b) Since the allele for white is W, <u>the genotype for white chickens would be WW.</u>

c) Since erminette color is heterozygous,<u> the genotype would be BW.</u>

d) Two erminette were crossed:

         BW    x    BW

      BB BW BW WW

i. <em>Probability of having black chick (BB) </em>= 1/4

ii. <em>Probability of having a white chick (WW)</em> = 1/4

iii. <em>Probability of having erminette chicken (BW)</em> = 1/2

Misha Larkins [42]

Answer:

a. conservative replication

b. semi conservative replication

c. dispersive replication

d. discontinuous replication

e. continuous replication

The CORRECT ANSWER IS C.

c. dispersive replication

Explanation:

The attached image shows a single band that becomes lighter (in volume) and increase in darker intensity (in times of color) is revealed with consecutive replications. The major pattern that would produce these outcome is dispersive replication.

Conservative replication do reveal two bands (a 14N for the wholly latest molecule, and a 15N for the totally antiquated molecule) after the initial replication. Therefore, this wholly wrong.

Semi-conservative replication reveal an individual band of transitional weight after the initial  replication, followed by two bands following the second replication (one of transitional weight, and the other at the 14N position). These two bands is observed in each following replication, with the transitional weight becoming lighter in color as the 14N band is seen to appear darker in color.

The real pattern gives an individual band that pinpoints to all molecules in an individual replicative cycle possessing the same constituents.

Dispersive replication, has its molecules to be a blend of old (15N) and new (14N) strands. Each replication raises the ratio of new to old strands as it explains the reason an individual band is shown raised (lighter in weight) with every replication.
