Attached is the image of the concerned ECG reading.
In reading the ECG, first you read the heart rate. To read the heart rate, you must count for the number of small boxes in between QRS complexes, specifically R-R intervals. These number of small boxes will then be used to divide 1500. In this example, there are 20 small boxes between R-R intervals. 1500 divided by 20 is 75, so the heart rate of this ECG reading is 75 beats per minute.
<em>Another way, albeit less accurate, is to count the big squares between R-R intervals and instead of dividing it by 1500, you divide it by 300.</em>
Answer: The claim that gene regulation results in differential gene expression and influences cellular products (albumin or crystalline) is best supported by t<u>he specific transcription factors made in a cell.</u>
Explanation:
Genes store deoxyribonucleic acid or DNA that makes up the genome. The genetic information within genes is expressed through a process called transcription followed by translation.
During this, the genotype of the organism is changed into its phenotype or physical characteristics genes are controlled or regulated through certain molecular mechanisms These essentially determine transcription and translation and whether gene products is active or in active genes are turned on when they are able to transcribe the genome.
gene expression may be regulated
via
- modulation before or after the transcription process
- modulating translation
- modulation after translation
A control for the transcription process is called a transcription factor. These are DNA sequence specific proteins that are capable of activating or suppressing transcription at certain sites. In different cell types, different combinations of transcription factors contribute to gene expression.
Answer & Explanation:
There are often not more than one or two independent variables tested in an experiment, otherwise it is difficult to determine the influence of each upon the final results. There may be several dependent variables, because manipulating the independent variable can influence many different things.
Answer:
B) specific heat
Explanation:
The specific heat of a substance is how much heat per unit mass it need to elevate its temperature by one degree Celsius. Its units are joule per kelvin and kilogram, J/(K kg). <em>In the example given you can observe that water need more heat in order to evaporate compared to the alcohol.</em>
I hope you find this information useful and interesting! Good luck!
Answer: Evolutionary
Explanation:
Evolution of the male and female reproductive organs is necessary for the advancement of mating strategies that range from simple to complex living beings. This is a kind of adaptation those which have phenotypic characteristics favourable to attract the mates will reproduce the offspring. These traits will be passed on to the progeny and evolution of the species will take place.
