Answer: Saprophytic and parasitic
The fungi in general is a group of saprophytic as well as parasitic organisms that feeds upon the dead and decaying matter as well on the living organisms. These organism cannot prepare their own food by the process of photosynthesis like plants and other autotrophs but are dependent upon others organisms as well as dead matter for their food requirements.
Answer: "mutualism" (a type of "symbiosis"/ or "symbiotic relationship" between two organisms; in which each of the two interacting organisms benefits from each other.
Sometimes called. "mutualistic symbiosis" , or "symbiotic mutualism" .

Answer:
4: epistasis
Explanation:
<em>Epistasis is a form of gene interaction in which a gene on one locus modifies or suppresses the effects of another gene on a separate locus. </em>
Epistatic gene interaction can be dominant, recessive, duplicate recessive, duplicate dominant, or polymeric gene interaction.
- Recessive epistasis occur when a recessive allele at one locus suppresses the expression of alleles on separate locus/loci.
- Dominant epistasis occur when a dominant allele at one locus suppresses the expression of alleles on separate locus/loci.
- Duplicate recessive epistasis occur when recessive alleles at either of two loci suppress the expression of dominant alleles at the two loci.
- Duplicate dominant epistasis occur when dominant alleles t either of two loci suppress the expression of dominant alleles at the two loci.
- Polymeric gene interaction occur when two dominant alleles which have similar effect individually produce enhanced effect when they come together.
<em>In this case, the expression of gene is controlled by the presence/absence of gene N on a separate locus. In homozygous recessive form, gene N suppresses the expression of gene S, a clear case of recessive epistasis.</em>
The correct option is option 4.
Answer:
The main difference between prokaryotic and eukaryotic cell is D. Eukaryotic cells have a more complex cellullar organization.
Explanation:
The eukaryotic cells are different from prokaryotic because both have fundamental anatomical and biochemical distinctions. This distinctions are not a question of size or shape.
Some of the basic differences are:
Eukaryotic cells have a membrane enveloped nucleus and internal organelles as mithocondrial, lysosomal and golgi apparatus. Only these cells have chromatin structure.
<h3><u>Answer;</u></h3>
Chromatin
<h3><u>Explanation</u>;</h3>
- Prophase is the first phase of mitosis, which a type of cell division that takes place in the somatic cells, that separates the duplicated genetic material carried in the nucleus of a parent cell into two identical daughter cells.
- During this stage the genetic material is called chromatin, which is the complex of DNA and proteins contained in the nucleus.
- During prophase the chromatin is condensed and the chromosomes become more visible. DNA molecules are progressively shortened and condensed by coiling.
