Hello, Sameedfarooqui6

You see jellyfish adapted to not having a brain but they still have a nervous system. This nervous system goes to there tentacles which helpes jellyfish detect tempatures, touch, food etc.

If that did help i would gladly accept brainliest thanks duded and have a great day!

Harlamova29_29 [7]

Klinglers iron agar medium is used to find the enterobacteria which can ferment glucose , lactose and hydrogen Sulphide . They are H₂S producing bacteria .

This media have phenol red as an indicator. When the glucose is fermented to acid , the production of acid turn the indicator from red to yellow, but it is then reoxidised and turns red again . When lactose is fermented it produce large amount of acid , and turn indicator yellow . Hence the slant will become yellow.And combination of ferrous sulphate and sodium thiosulphate helps in detection of H₂S which produce black color at the butt .

You are involved in an experiment involving fluorescent painting of chromosomes. You observe the following in a nucleus experien
Galina-37 [17]

Answer:

It seems that a reciprocal translocation is going on.

Explanation:

A translocation occurs when a chromosomal fragment changes its location in the same chromosome from the original to a new one. Or when it leaves the chromosome to re-locate in a new different chromosome.

According to this, there are different types of translocations:

  • Intrachromosomal translocations:
  1. Intra-radial: the change in position occurs in the same arm of the chromosome. For instance, 123.456789 → 123.478569
  2. Extra-radial: The change in position occurs from one arm to the other of the same chromosome. For instance, 123.456789 → 15623.4789
  • Extrachromosomal translocations:
  1. Transposition: not reciprocal interchange. The fragment leaves a chromosome to re-locate in another chromosome. The other chromosome does not send any fragment to the first one.
  2. Reciprocal translocation: There is a reciprocal interchange. A fragment of chromosome A goes to B, and a fragment of chromosome B goes to A.

Reciprocal translocations might be:

  1. Fraternal: the interchange occurs among homologous chromosomes
  2. External: the interchange occurs among non-homologous chromosomes

Reciprocal translocations are easily recognized during meiosis because an association between four chromosomes can be observed.  This association is a quadrivalent structure.

During metaphase 1, the centromeres involved in the quadrivalent originate centromeric co-orientation or disjunction.

igor_vitrenko [27]

Answer:

The experimental results cannot be reproduced.

Explanation:

The ability to follow a specific set of procedures and achieve the same results is one of the key parts of the scientific method.  If the results cannot be replicated, the study is invalid.  Unfortunately, results of invalid studies are sometimes announced to the public before replication attempts can be made to invalidate the study.  Trying to reverse public belief at that point can be impossible.

What stuff is always part of using the scientific method?
Kay [80]
Since you provide no options, here are the usual parts of scientific method :

- Idea / question which answer you want to find out 
- Research , collecting all kinds of data 
- Hypothesis , an explanation that is made at the starting point, before the experiment
- Experiment , to find out whether your hypothesis is right
- Analyze the data that you got from the experiment
- Conclusion, your final judgement based on the result of your experiment

IceJOKER [234]

Answer:

Nothing

Explanation:

A. Control variables generally entail little or no system change. To see if the method worked, the researchers required a positive control in which the heat-killed virulent bacteria invariably transformed the non-virulent microorganisms. This positive control involves adding "nothing" to both the heat-killed virulent bacteria before mixing them with the non-virulent bacteria.
