Tides are caused by gravity
Answer: The NEGATIVE CONTROl is the test tube that is filled with ONLY distilled water.
Explanation:
A negative control of an experiment is carried out alongside the main primary experiment except that the treatment is changed to something that is predicted to have no result. In the negative control, the student does not expect any response. This would help the student compare the result of a new experiment against an already known existing results.
Analysing the experiment carried out by the student, She filled two test tubes with distilled water and placed a piece of Elodea in one of the tubes, leaving the other without a plant. The other test tube that contains only distilled water is the negative control because she wasn't expecting any result from it. It's also served as a control sample to the primary experiment. This is observed as she blew in each tube to add carbon dioxide, which caused the distilled water to become more acidic. This would help the student know that the that experimental results are valid and to ensure that time is saved.
Betaxolol belongs to the drug class of beta blockers wherein these drugs block the action of the beta adrenergic receptors in different organs, including the heart and the bronchial tissues. Oral beta blockers (i.e. Propranolol) must be avoided because there can be additive effects of the ophthalmic drops and the oral drug and may cause severe bradycardia (and/or asthma exacerbation, if the patient has asthma).
The place of the diencephalon that bureaucracy the ground of the 1/3 ventricle and extends anteriorly to the optic chiasm is the <u>hypothalamus</u>.
The thalamus, a skinny vertical area full of CSF referred to as the third ventricle is located midline among the 2 halves of the hypothalamus thalamus. The hypothalamus extends anteriorly to the optic chiasm and posteriorly to consist of the mammillary our bodies at the ventral floor of the brain. The hypothalamus and thalamus are placed on the edges of the 1/3 ventricle. Abnormalities of the 1/3 ventricle are related to numerous situations together with hydrocephalus, meningitis, and ventriculitis.
Hydrocephalus is an immoderate buildup of fluid at the brain. The anterior wall of the 1/3 ventricle is shaped from advanced to inferior through the columns of the fornix, the anterior commissure, and the lamina terminalis 4. Posteriorly, it's far bounded from advanced to inferior through the habenular commissure, the pineal gland, and the posterior commissure.
