Answer A)

The gene would not be transcribed. This is because the gene transcribing machinery would not be activated if the promoter sequence is not recognized. Transcription will not start.

Answer B)

The gene would not be transcribed. This will result in no RNA polymerase being formed. Hence, transcription and translation will not occur.

Answer C)

The mRNA would contain intron sequences, which would be translated into extra amino acids in the protein. A non- functional protein would be made.

What's the main function of the Krebs cycle
kati45 [8]
The main function of the Krebs cycle is to generate energy for the cell. The Krebs cycle is also known as the citric acid cycle and is part of cellular respiration. Cellular respiration is a series of chemical reactions that cells use to break up sugars into a form that the cell can use. Cell respiration requires oxygen to take place. Cellular respiration consists of four stages:1. the breaking down of glucose into molecules (glycolysis)2. the link reaction - this process forms a link between glycolysis and the Krebbs reaction3. Krebbs reaction 4. The electron transport chain

PROJECT: HOMEOSTASIS
Semenov [28]
Maintaining Homeostasis. The process in which organ systems work to maintain a stable internal environment is called homeostasis. ... Endocrine system: A high concentration of sugar in the blood triggers secretion of insulin by an endocrine gland called the pancreas.
The normal blood glucose level (tested while fasting) for non-diabetics, should be between 3.9 and 5.5 mmol/L (70 to 100 mg/dL). ...
 Blood sugar levels for those without diabetes and who are not fasting should be below 6.9 mmol/L (125 mg/dL).
There are lots of different hormones in the human body that serve lots of different functions, but some are used to maintain homeostasis of various physiological parameters, like blood glucose levels. Blood glucose levels are regulated by two opposing hormones: insulin and glucagon.

Which term describes the perception of the body’s movement through space?
Bingel [31]

Answer:

Option C

Explanation:

Complete question

Which term describes the perception of the body's movement through space?

A. nociception

B. neurasthenia

C. kinesthesia

D. dimensionality

Solution

The word Kinesthesia is made up of two words kinetic and anesthesia. On one side kinetic means movement while anesthesia means feeling, sensation, visions etc.  

Whenever a person senses his/her body movement through space or any other kind of physical bodily movement or action, he/she actually faces Kinesthesia. This is also related with the Charles bell concept of sixth sense through which one could perceive sensation of static position or velocity of the movement

 Hence, option C is correct

What would be the best negative control to use when testing for any organic compounds
ra1l [238]

Explanation:

A similar question was asked online, here is the answer it gave:

'“Negative control” is a treatment that by definition is expected not to have any effect (neither positive effect, nor negative effect). “Positive control” is treatment with a well-known chemical that is known to produce the expected effect with the assay that you are studying. Application of an antagonist is not a negative control in your case. “Negative control” is condition that should be treated with the same solutions or buffers as your “treatment” condition, with the only difference that instead of the chemical that you investigate you should add just the solvent that was used to dissolve you chemical in the respective final concentration that you have in the “experimental treatment” condition. For example if your chemical is dissolved in DMSO – than the correct negative control will be to add to the medium/buffer just DMSO in the same final concentration that you reach with your “treatment” condition. One of the reasons of using such negative control is to verify that the solvent is having no effect in your assay. Note that among all treatment conditions (“negative control”, “positive control”, “experimental treatment you are investigating”) the volumes and the composition of the treatments that you are doing should be uniform: always treat with the same volume of medium or buffer, always containing the same concentration of the used solvent (e.g., DMSO). The only difference should be the presence or absence of the defined compound-treatments (agonist, antagonist, the chemical for the experimental investigation etc.).'

My best advice is to use the textbook you have, or use examples of a negative control when testing organic compounds because you have to find something that you can assign, like a worm in a box of dirt, the worm could have enough food to survive, so that is your negative control, but when it comes to finding the best, that would have to rely on something within the parameters of being self sufficient like a plant getting its energy from photosynthesis, etc.
