Answer:
soil; rice
Explanation:
Bacillus cereus is naturally found in the soil. B. cereus is known to contaminate rice, which, if undercooked and ingested, can lead to gastroenteritis. In this example, the reservoir for B. cereus is the soil, and the source of infection is the rice.
A reservoir refers to the breeding ground or natural habitat of micro living organisms such as bacterias, fungi, worms, etc. Thus, a reservoir hosts or harbours pathogens and usually serves as a source of infection to other living organisms.
On the other hand, a source of infection refers to a contaminated material from which a disease can be acquired by another living organism.
The answer is environmental stress
Answer:
1. The Diet Pills
2. The Height Of the plants
3. The plant being watered with tap water
4. 8 Trials were included
Explanation:
1. An independent variable is the variable that you change
2. The dependent variable is what you are measuring, in this example the height of the plant
3. This is what you use to base your conclusion on. In this test they are seeing if diet pills affect the height of the plants. So a plant with no diet pill is the control
4. The results were taken at the end of the week for EIGHT weeks. 8 Trials.
Answer:
Potential targets:
1- DNA methyltransferases
2- Chromatin modifiers such as histone acetyltransferases, histone deacetylases, histone methyltransferases, etc.
3- Components of the RNA interference (RNAi) machinery such as Dicer, Argonaute, etc.
Explanation:
Epigenetics can be defined as the study of any heritable change in the phenotype that does not involve modifications in the DNA sequence. Epigenetic mechanisms can be classified into three major types: 1-DNA methylation, 2-histone modifications (e.g., acetylation, methylation, phosphorylation, etc), and 3-regulatory non-coding RNAs (e.g., miRNAs, lncRNAs, siRNAs, etc) that modulate target gene expression via the RNA interference pathway. There are different types of proteins that are involved in these complex epigenetic mechanisms, and those cited above represent only some examples that can be used as therapeutic targets.
The most likely answer here is 1 and 4.
