Answer:In miasma theory diseases were caused by the presence in the air of a miasma, a poisonous vapour in which were suspended particles of decaying matter that was characterised by its foul smell by removing the causes of bad smells reformers often inadvertently removed bacteria, the real cause of many diseases
Explanation:
The movement of leaves of sensitive plants is known as a nastic movement, while the movement of a shoot towards light is known as phototropism.
<h3>What is a Nastic movement?</h3>
A nastic movement may be defined as a type of movement or response of numerous parts of the plants that are significantly independent of the direction of the external stimulus.
The movement of leaves of the sensitive plants is independent with respect to the direction of the external stimulus and thus is known as a nastic movement.
While the movement of a shoot towards light is known as a tropic movement. This type of movement significantly depends on the direction of external stimuli like the direction of light. And hence is known as phototropism.
Therefore, it is the major difference in the movement of leaves of the sensitive plant with respect to the movement of a shoot towards the light.

Answer:
Transmission of genetic information from parent to offspring is termed vertical gene transfer. Lateral movement, or movement of genetic information from a donor to an unrelated recipient, is called horizontal gene transfer.
Explanation:
( happy to help) :)
Ectopic focus or ectopic pacemaker happens when an excitable group of cells outside the normal sinoatrial node causes premature heartbeat. Sinoatrial node (SA node) is the pacemaker of the heart. Most people experience ectopic focus but persistent occurrence may need the client/patient to visit the doctor. If a client or patient complains of ectopic focus, it is better to consider his/her activity before visiting the clinic. Ask, for example if the client/patient had a vigorous exercise because it might be causing the irregular heartbeat, how often is he/she experiences such irregularity in his/her heartbeat (acute ectopic foci is usually non-life threatening, however, chronic type requires medical help), his/her lifestyle (he/she might be using illegal drugs, smokes and/or drinks alcohol,had too much coffee etc). Again, history taking is very vital.
The best answer would be:
A. DNA is being transcribed into mRNA.
If you'd like to know why:
In the image shown, you can see the <u>BLUE </u>strands and the <u>RED </u>strand. The Blue strand is DNA and the Red strand is mRNA. What is happening in the picture is TRANSCRIPTION. It is the process of making an RNA copy of the DNA strand to create proteins based on the DNA strand.
The <u>GREEN</u> blob is most likely RNA polymerase. Its job is to synthesize or make a complementary RNA strand of the DNA by assembling nucleotides to form an RNA strand based on the DNA template.
