In general, one species wins, and one species is eliminated. These experiments gave rise to the competitive exclusion principle: No two species of similar requirements can long occupy the same niche (coexist). In the case of paramecium, the same species always won.

2nd one is the right answer
Chordates are animals that possess certain characteristics including a notochord. Humans fall into this category along with many vertebrates such as whales, falcons etc; therefore, all of the answers apply.
Food, research, therapy, entertainment affection.
Answer:
Explanation:
a) the cardiovascular condition is sabacute endocarditis
b) It is caused by a type of streptococcus called streptococcus viridians and transmitted through the opening of the wound
c) rheumatic fever can lead to damage to the heart and this damage allows bacteria to attach itself to the heart. Streptococcus viridians are often caused by bacteria hence there growth can be favorite by rheumatic fever.
d) the nails is used to check the blood stream, and should be check for capillary heamorrhage
e) He would order for BAP- Bacteria Agar plate that is used mostly to classic streptococcal bacteria.
Answer:
There are many points at which eukaryotic gene expression can be controlled, through pretranscriptional control, transcriptional control, and posttranscriptional control
Explanation:
The pretranscriptional control determines the accessibility of chromatin to the transcription machinery. It is affected by supercoiling and methylation. It is also known as epigenetic regulation, and it does not depend on the sequence but on the conformation of the DNA.
While transcriptional control determines the frequency and / or speed of transcription initiation through the accessibility of the start sites, the availability of transcription factors and the effectiveness of promoters.
The post-transcriptional control is the one that is exercised once the transcript has finished synthesizing. It can be of several types:
• Maturation control: As the RNA adjustment can be made.
• Transport control: Most RNA has to go out to the cytoplasm to perform its function. For this they have to cross the pores of the nuclear membrane, where you can select the RNAs that will be transported and those that will not.
• Stability control: The half-life of RNA can be regulated by the expression of RNAs or mRNA stabilizing proteins in the cytoplasm.
• Translational control: It is exercised on the frequency with which the mRNAs begin to be translated. It can also affect the frequency with which proteins mature and the availability of enzymatic effectors.
