Answer:

1) vacant parking lot for many years (secondary succession)

2) abandoned baseball field (secondary succession)

3) recently cooled lava field (primary succession)

4) rocky hill under a melted glacier (primary succession)

5) clear-cut forest (secondary succession)

Explanation:

Succession in ecology is the gradual encroachment of life on a given ecosystem.

Primary succession involve a new never-before colonized region like a new lava deposit or land hidden under glacial sheets. Secondary succession is the encroachment of life on an area formerly harboring life but had experience a disturbance like wildfire, agricultural activities, logging etc.

In a hypothetical population of plants, flower color is determined by a single gene with two alleles. In a population of 500 pla
blondinia [14]

Answer:

In the F1 generation

RR = 0%

Rr = 50% (or 0.5)

rr = 50% (or 0.5)

Explanation:

A pink flowering plant has the genotype Rr. It is heterozygous for the allele. The alleles for this gene appears to show incomplete dominance, as the heterozygous phenotype is a blend of the two homozygous genotypes.

A white flowering plant has the genotype rr. It is homozyogous for the white allele

A punnet square of the cross is shown.

The resulting punnet square shows that only Rr and rr genotypes are possible, at a ratio of 50:50 (or 1:1). Therefore, the genotype frequency of Rr is 50%, and rr is 50% in the F1 generation. This can also be written as 0.5. It is not possible to get a red plant, as the genotype RR can not come from this cross

Karo-lina-s [1.5K]

Answer:

The correct answer is "motor unit - motor neuron".

Explanation:

Motor unit and motor neuron are related terms, however they could not be used interchangeably because a motor unit is not comprised only of a motor neuron. A motor unit is made of a motor neuron, skeletal muscle fibers and neuron's axonal terminals. Therefore motor unit is a more broadly term, and is referred to the units that coordinate the contractions of single muscles.

Before starch can enter a cell, it must be
SOVA2 [1]

Answer:

C.

Explanation:

Starch are macromolecules that are made of monomers that are simple sugars. Cells are microscopic and they can only absorb small substances. Therefore starch needs to be digested in other words broken down into simpler substances that can be taken in by cells. Therefore before starch can enter a cell it must be 3) digested to form simple sugars
