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.
Quick Answer. Collagen is the protein that all animals have in common, even single-celled animals and creatures such as sponges that lack differentiated bodies. Collagen is a cable-like protein that can calcify into bone, shell or other hard structures.

Answer:
C. Liver cells being generated by air
Explanation:
This statement would be an example of abiogenesis, or spontaneous generation (which is proven to be impossible). Cells can not appear out of "thin air" (if you know what I mean haha. Hope this helps!
The answer to the question is 7.4%.
<h3>How to calculate production efficiency?</h3>
Energy from food is 5000 J
Energy lost in feces is 2300 J
Energy used in cellular respiration (metabolism) is 2500 J
The production efficiency of consumer in an ecosystem is given by
(Energy from food- Energy lost in feces-Energy used in cellular respiration (metabolism)) divided by (Energy from food- Energy lost in feces)
= (5000 - 2300 - 2500)/ (5000 - 2300)
= 7.4
<h3>What is
production efficiency?</h3>
Energy transfer efficiency from one trophic level to the next is referred to as ecological or production efficiency. It is determined by a variety of assimilation and resource acquisition efficiency for organisms within an ecosystem.
The average efficiency of energy transfer between trophic levels is such that net production at one trophic level is often only 10% of net production at the trophic level before it (the Ten percent law). In contrast to being absorbed for production by consumers, a sizeable quantity of energy is lost to the environment as a result of non-predatory mortality, egestion, and cellular respiration. Although these fractions differ significantly from ecosystem to ecosystem and from trophic level to trophic level, the picture roughly represents the fraction of energy available after each stage of energy loss in a typical ecosystem.

The correct answer is A. To produce glucose.
This is correct because a plant goes through the process of photosynthesis in order to create "food" for itself.
Hope that helps!
