What makes an allele dominant recessive or codominant
kati45 [8]
Dominant refers to the relationship between two versions of a gene. Individuals receive two versions of each gene, known as alleles, from each parent. If the alleles of a gene are different, one allele will be expressed; it is the dominant gene. The effect of the other allele, called recessive, is masked.

Explain how the use of Restriction Fragment Length Polymorphisms to diagnosis genetic disease differs from its use in forensic i
saw5 [17]
RFLP or Restriction Fragment Length Polymorphism exploits the variation of homologous DNA (Deoxyribonucleic Acid) sequences. This technique is frequently used in different types of analysis such as genotyping, paternity tests, forensics, hereditary disease diagnostics, and many others. In diagnosing diseases, PCR is use to find the DNA of pathogens in small amounts to diagnose hundreds of genetic diseases. While in forensic investigations, PCR can give a probably ID from 20 cells.

What kinds of organisms can perform photosynthesis? Which types of organisms cannot?
Neporo4naja [7]

<u>Answer:</u>

Most plants, most algae and cyanobacteria kinds of organisms (Autotrophs) can perform photosynthesis while heterotrophs are organisms incapable of photosynthesis.

<u>Explanation:</u>

Photosynthesis is a mechanism used among plants as well as other species to transform energy from the sun into chemical energy which may be released later to power the functions of the species.

In autotrophs (organisms who self prepare there food ) with the support of a subsequent series of light-independent reactions like Calvin cycle, creates long-term energy collection in the form of sugars, while some bacteria use different mechanisms like the reverse Krebs cycle to accomplish the same purpose.

Heterotrophs are entities unable to photosynthesize and, by eating certain species, must therefore obtain energy and carbon from the food. In the term heterotroph: hetero means "other" while troph means "feeder", thus their food depends on other species.

Otters have adaptive traits that allow them to survive by eating shellfish and crustaceans, the otters will most likely:
FinnZ [79.3K]

Answer:

<em>The correct option is C) Experience a population decline</em>

Explanation:

The population of Otters will remain stable if the population of the preys i.e shellfish and crustaceans, remains stable in an ecosystem. If the population of shellfish and crustaceans begins to decline in an ecosystem, then there will be competition for food among the Otters and other organisms which feed on shellfish and crustaceans. As a result, the population of the Otters will also start to decline due to lack of food.
