The diagram below represents a structure found in most cells.

Where would you find hemoglobin that is relatively o2 poor in a healthy resting person?.

Answer:

Venous blood

Explanation:

Arterial blood is carrying oxygen to tissues.....after delivering the oxygen it is venous blood and has less oxygen.

I need help with 4 & 5 ASAP please

One option is that the samples run through gel electrophoresis is too small to be recognized (shorter strands of DNA travel further through the gel and larger strands travel shorter). The other option in that the restriction enzyme did not cut the DNA in the proper spot or there was a mutation in the bases that allowed for a mistake in the cutting; that is why there are 800 base pairs in one sample (that's a lot) An example of a mutation is that lets say the restriction enzyme was supposed to cut at the second G in GGACC. But if that G was turned into an A, then the restriction enzyme wouldn't cut there.

For number 5, you might have 800 because of the restriction enzyme cutting it wrong, a mutation that allowed for the cutting to not take place, or a fault in the sample taking.

I am an AP Biology student right now in Wisconsin. I just finished that worksheet this morning :) anymore questions just hit me up

Wave is a periodic (1) __________ that moves away from a source which carries (2) __________ with it. Waves can be typified acco

The correct answers to fill into the blank spaces are;

Wave is a periodic disturbance that moves away from a source which carries energy with it. Waves can be typified according to the direction of motion of the vibrating particles with respect to the direction in which the waves travel and according to medium .

Longitudinal waves vibrate perpendicularly to the direction in which the waves travel. This wave exhibits up and down motion. Longitudinal waves vibrate perpendicular or back and forth to the direction in which the waves travel.

Electromagnetic waves are combination of transverse and longitudinal waves. These move in a circular pattern as the waves pass by.

Mechanical waves need solid, liquid and gas medium to propagate or travel. Transverse, mechanical and surface waves are examples of mechanical waves.

Electromagnetic waves do not need medium to propagate. Radio waves, ultraviolet, infrared, and gamma rays are examples of electromagnetic waves. The nature of waves can be described through its terms, quantities and propagation.

The crust and trough refer to the highest point and lowest point of a wave pattern, respectively. The magnitude of a transverse wave is the maximum displacement of a particle of the medium on either side of its normal position when the wave passes. The frequency of periodic waves is the number of waves that pass a particular point for every one second while the Amplitude is the distance between adjacent crests or troughs.

The period is the time required for one complete wave to pass a particular point. The speed of the wave refers to the distance the wave travels per unit time. It is related to the frequency of the wave and wavelength through the following equation: wave speed= frequency x wavelength.
