There is no mating or mixing of genetics in asexual reproduction. Asexual reproduction results in a clone of the parent; the offspring has identical DNA as the parent. There is usually no variation from generation to generation in a species population that relies on asexual reproduction.

One way for an asexually reproducing species to get some diversity is through mutations at the DNA level. If there is a mistake in mitosis or the copying of the DNA, then that mistake will be passed down to the offspring, thereby possibly changing its traits. Some mutations do not change the phenotype, however, so not all mutations in asexual reproduction result in variations in the offspring.​

natali 33 [55]

The effects of exercise on heart rate can be studied by analyzing the number of heart pumps according to physical exercises, while control variable is room temperature.

<h3>What is an independent variable?</h3>

An independent variable is any variable that isn't changed along the experimental procedure, while the dependent variable is modified by the conditions.

The sample size must be statistically significant (N sample size higher than 50 individuals) and a number of trials at least two to compare results.

In conclusion, the effects of exercise on heart rate can be studied by analyzing the number of heart pumps (dependent variables) according to physical exercises (independent variable), control variable is room temperature.

What is the most important reason for food handlers to understand and apply food safety knowledge?
stealth61 [152]
The most important reason for food handlers to understand and apply food safety knowledge is to prevent the spread of illnesses through food.
Food workers play a critical role in ensuring food safety, those who do not practice proper personal hygiene, including hand washing at appropriate times and using appropriate methods can contaminate food. It is therefore; very important for food workers to understand and apply food safety measures so as to prevent spread of diseases through food.

Aneli [31]

Answer:

Transcription, mRNA (processing, transport, localization and stability), translation.

Explanation:

  • Transcription is regulated in two levels, though chromatin regulation (methylation and acetylation) to loose or increase histone's affinity to DNA and through cis and trans elements such as promoters, enhancers, and silencers (cis) to active/deactivate and RNA polymerase and transcription factors and co-factors (trans).
  • mRNA can be regulated using poly-A tails or 5'-caps to shorten or give them more time before they degrade, it could also be spliced to eliminate introns.
  • In the translation stage, the regulation occurs during the initiation through a scanning procedure that ensures the 40s ribosomal subunit bind correctly to the untranslated portion of RNA

Hope this information is useful to you!
