During an influenza outbreak, many people get infected and die. However, part of the population acquires immunity and survives. This is due to variations in the genotype and phenotype among individuals in the population. Probably a particular phenotype confers resistance to influenza. Therefore, this population is able to grow and develop to maturity and reproduce. Their genes are therefore passed over to subsequent generations.

Plants use carbohydrates to build things such as cellulose. How do plants acquire these building blocks to build mass?
AlekseyPX

Answer:

Photosynthetic process

Explanation:

Cellulose, a tough, fibrous and water-insoluble polysaccharide in the cell walls of plants. It is the most abundant organic macromolecule on Earth and also the main component of a plants structure, conferring rigidity on the plants' cells.

Cellulose chains are arranged in microfibrils or bundles of polysaccharides arranged in fibrils which in turn make up the plant cell wall.

All plants are made up of polysaccharides, a very large sugar molecule made of hundreds or thousands of single sugar units (monosaccharide). Cellulose is composed of a long chain of at least 500 glucose molecules joined together by B-1,4- linkages.

Green plants create this simple sugar molecules (glucose) on their own through the process of photosynthesis. Photosynthesis is the chemical combination or fixation of C02 and water by the utilization of energy from the absorption of visible light. This glucose produced is a building carbohydrate that combines with other sugars to form the plant structure (as they make up part of cellulose) and store energy.

Answer:

According to the image, the approximate QT interval is 0.4 seconds.

Explanation:

The QT interval is the space between the beginning of the QRS complex and the end of the T wave, which represents from the beginning of depolarization to ventricular repolarization.

Considering that the extandardized measurements of an EKG, where the paper circulates at a speed of 25 mm/s, 1 mm horizontal —measuring time— has an equivalence of 0.04 s.

In the image, there is 10 mm between the beginning of the QRS and the end of the T wave, so:

    0.04 seconds X 10 mm = 0.4 seconds.

Then, the estimated QT interval is 0.4 seconds.

You are watching sleep researchers monitor the sleep of a normal adult. The participant is hooked up to an EEG. What brain waves
guajiro [1.7K]

Answer:

The correct answer is option b. "Alpha eventually replaced by theta".

Explanation:

Electroencephalogram (EEG) techniques allows researchers to monitor the phases of sleeping according of what brain waves are seen in the equipment. A normal adult connected to EEG will respond with alpha waves during a wakeful state. However, as the person becomes drowsy and enters to the first stage of sleep, the alpha waves will be eventually replaced by theta waves. Theta waves are the dominant waves during sleeping, and also could be seen during deep meditation.
