Answer:

The answer is B

Explanation:

because magnetic resonance imaging is a form of medical imaging that measures the response of the atomic nuclei of body tissues to high-frequency radio waves when placed in a strong magnetic field, and that produces images of the internal organs.

Put the following processes of protein synthesis in the correct order.
diamong [38]

<u>Correct sequential order for the following processes of protein synthesis are as follows:</u>

  • DNA strands unwind and separate
  • mRNA copies DNA according to complimentary base pairing  
  • mRNA leaves the nucleus
  • tRNA’s anticodons bring amino acids to the corresponding mRNA codons at the ribosomes
  • amino acids bind to each other making a polypeptide
  • a stop codon is reached, the newly formed a protein is released to go do its job for the cell

Option A --> B --> C --> E --> D -->F

<u>Explanation:</u>

Protein synthesis involves three major steps which are Replication of DNA, which is then transcribed and then translated to form protein, so the steps are Replication, Transcription and Translation.

Firstly, the DNA is a double stranded molecule which needs to be unwind as a replica where one of the strand becomes the template strand and transcription of strand occurs with mRNA.

mRNA thus leaves the nucleus and reaches cytoplasm where translation takes places and the tRNA provides specific anti codons to the mRNA codons and the amino acids are formed.

All amino acids bind to each other in order to make a polypeptide and hence the protein molecule newly formed is released to the cell.

Noe is studying Wave A and Wave B. Wave A is rated at 100 dB, and Wave B is rated at 90 dB. Which statement can be made about th
Vera_Pavlovna [14]

Answer: B.  Wave A is louder than Wave B.

Explanation: The loudness of sound is measured in unit called decibels (dB).

A decibel unit measures the relative intensity of sounds on a scale from zero to about 100 dB. dB is a measure of intensity, which relates to how much energy the pressure wave has.

Given : Wave A is rated at 100 dB, and Wave B is rated at 90 dB.

Thus we can infer that as wave A has a higher value than wave B, wave A is more louder than wave B.

. How many cotyledons would be found in a flowering plant with nine petals on each flower and long leaves with parallel leaf vei
ale4655 [162]
Theres monocotyledons and dicotyledons. (1 and 2 cots)
the answer should be monocotyledons, we can see that through the leaves and the petals. monocotyledons the petals r usually in the multiples of 3 or 6, and 9 petals is the multiple of 3. also, monocots leaves r usually in parallel leaf veins, so your plant is monocotyledons, which means one.

just in addition, dicots petals r in multiples of 4 or 5, and their leaves r usually in branched veins

Which component of the electrocardiogram represents the duration of ventricular contraction?
Advocard [28]

QRS complex refers to the combination of the Q, R, and S waves, and indicates ventricular depolarization and contraction (ventricular systole).

Ventricular rate can be calculated by determining the time interval between QRS complexes. The duration of the QRS complex is normally 0.06 to 0.10 seconds. This relatively short duration indicates that ventricular depolarization normally occurs very rapidly.

P QRS and T waves in electrocardiogram signifies the P wave in an ECG complex indicates atrial depolarization. The QRS is responsible for ventricular depolarization and the T wave is ventricular repolarization.

Is the correct order in a homeostatic feedback system stimulus, receoptor, control centre, effector?
Fantom [35]

Answer:

Correct

Explanation:

Homeostatic is nothing but ability of a system or living organism to manipulate its internal environment to maintain a stable equilibrium, for example the ability of warm-blooded animals to ascertain a constant body temperature.

The Homoeostatic feedback mechanism has three basis components and they are independent to one another.

These components are receptor, effector and integrating center. The function of receptor is to sense external stimuli and send information to integrating center. The integrating center generally hypothalmus in brain sends this signal to effector for example an organ to react to the stimuli.

So, the order  in a homeostatic feedback system stimulus, receoptor, control centre, effector is correct.
