Suppose that a leaf disk that has had the air sucked out is placed in bicarbonate solution under a dim light that results in a l

ow rate of photosynthesis that just equals the rate of cellular respiration. Would you expect this leaf disk to float? Explain why or why not.

The answer is; NO


This is because the leaf would not have tiny oxygen bubbles spread across its base (because the base is where most stomata are) that would help it float on the water. The reason is that the oxygen produced in the process of photosynthesis would be consumed in respiration because the rates of the two biochemical processes are the same.

bezimeni [28]

The answer is 4ml

Lasix is made of furosemide, a diuretic drugs that frequently used. To know the volume of drug needed, you need to divide the dose needed by the drug concentration. The dose gien is 40mg per dose while the concentration of the drug is 10mg/ml. The drug administered per doses would be: 40mg/ (10mg/ml)= 4ml

A controlled experiment___. A. Includes one group for which the scientist controls all variables. B. Includes at least two group
notsponge [240]

Answer:

The correct answer is:

Includes at least two groups, one of which does not receive the experimental treatment. (B)

Explanation:

A controlled experiment is made up of at least two groups of participants (subjects). One group (the test group) receives the experimental treatment, which can be an intervention or a new drug to be tested etc, and the effect of the treatment on the subjects is measured, while the second group of similar subjects also known as the control group acts as a baseline and do not receive the treatment or intervention. They act as a baseline to ensure that the change observed in the treatment group was brought about as a result of the treatment.

<em>Note that repeating the experiment several times does not ensure accuracy of the result, rather it ensures reliability of the results hence option D is not correct</em>

1) Bacteria respond to changes in their environments, such as nutrient availability, by regulating their metabolic pathways. Des
nasty-shy [4]

Answer:

Examples:

- Short-term adaptation: feedback inhibition

- Long-term adaptation: regulation of gene expression

Explanation:

Feedback inhibition is a mechanism where the product of a chemical reaction is utilized to modulate its own subsequent synthesis. In bacteria, feedback inhibition allows regulating different metabolic pathways in response to environmental conditions by modulating enzyme activity through enzyme reaction products. Moreover, bacteria may also respond to environmental inputs by long-term changes in gene expression. For example, bacteria contain transcription factors activated during stress, which are able to activate the transcription of particular genes into messenger RNAs (mRNAs) that would subsequently be used to generate particular enzymes by the process of translation. These transcription factors may bind to specific DNA motifs in order to promote transcriptional activity, thereby regulating the production of the corresponding enzyme.
