Answer:
See explanation below.
Explanation:
<em>Study Design - Partially double-blinded study</em>
- The <u>cohort study </u>will be composed of 80 adults (aged ≥18 years) with a clinical diagnosis of constant coughing present as a result of a cold, which would be measured by semiautomated ambulatory cough monitor.
- This study will be divided into an experimental group and a control group:
- No medication (natural drops; <em>e.g.</em> water; saline solution) - <em>Control group </em>
- Cough treatment - <em>Experimental group</em>
Participant cough will be recorded <u>every hour</u> (until 8 hours are reached) for two consecutive days (for repetitions) in both groups using semiautomated ambulatory cough monitor and analyzed statistically.
Experimental group: <u>If coughing is significantly (statistical analysis) reduced within the 8 hours </u>(<em>after repetitions</em>) and a symptom improvement is observed, <u>the hypothesis that cough drops are effective is valid</u>.
Control group: To determine that cough drops treatment is effective, the no-treatment group should score worst and participant should not show significant improvement.
*<em>In scientific experiments, repetitions are important to prevent bias and error.</em>
<h2>d) option is correct </h2>
Explanation:
The stringent response occurs in response to low energy store
For example when there is low level of lactose it means energy level is low so there will be no transcription of genes and hence transportation and catabolism of lactose will be inhibited
When E coli is grown in mixture of both glucose and lactose, at high glucose concentration the growth rate is maximum and lactose catabolism is repressed, this called as catabolite repression and it is due to level of cAMP
The cash crops are the crops, which has more commercial values as compared to the normal crops. The cash crops are essentially grown for the purpose selling.
The Europeans forced the native Americans and Africans to grow commercial crops, which include cocoa, peanuts, coffee, sugar,cotton, palm oil, rubber, tea, timber and tobacco. Out of which, tea, cotton and tobacco were the most forced cash crops.
Hence, the correct answer is tea, cotton and tobacco.
Here's the balanced chemical equation for the given Reaction,
- 2 HCl + 2 Na =》2 NaCl + H2

Answer:

Explanation:
Ribosomes are specialized to carry protein synthesis [Manufacture of protein]. Since, Ribosomes are attached to rough endoplasmic reticulum which means that the function of RER is also protein synthesis. If a cell has a very large amount of ribosomes attached to its rough endoplasmic reticulum, Then the cell will probably carry out the manufacture of protein.
Hope this helped!
