Answer:
D. they are usually dominant or recessive.
Explanation:
alleles are pairs of genes found on a particular spot a chromosome. If one is dominant over the other it give rise to a particular trait.

Plasmodesmata can change in number, and when dilated can provide a passageway macromolecules
Plasmodesmata are essential for the intercellular transfer of both big informational macromolecules like proteins and smaller signaling chemicals in plant cells.
- Plasmodesmata are membrane-lined structures that offer a high-conductance, aqueous channel for the transportation of information in the form of chemicals and macromolecules, such as transcription factors, from cell to cell.
- The intimate interaction of the plasma membrane with the endoplasmic reticulum results in the formation of plasmodesmata.
- The degree to which a particular cell acts as an individual or as a component of the entire organism is determined by the distribution and unitary conductance of plasmodesmata as well as other positional variables that affect development.

#SPJ4
Reducing sugar is any sugar (all monosaccharides, some disaccharides, oligosaccharides, and polysaccharides) that is capable of acting as a reducing agent because it contains free aldehyde group or free ketone group.
Aldehyde group or alkanal is an organic compound containing formyl group. The formyl group is a functional group consisting of a carbonyl center bonded to hydrogen and an R group. This group can be readily reduced to primary alcohol with the help of catalyctic hydrogenation either applied directly or by transfer hydrogenation.
Ketone group unlike aldehyde group does not have a hydrogen atome bonded to the carbonyl group but it can still be hydrogenated.
Answer:
This question lacks options, however, primary succession will be explained for detailed comprehension.
Explanation:
Ecological succession is the gradual series of changes that occurs in an ecosystem, charging it's structure and composition over time. It is of two types namely; primary and secondary successions.
Primary succession is characterized by the "LACK OF NO SOIL". It begins on a barren piece of land e.g rocks, with no form of life previously known to colonize the area. In primary succession, the barren land is first colonized by organisms such as lichens etc., which are collectively regarded to as PIONEER SPECIES.
