<u>Answer:</u>
Most plants, most algae and cyanobacteria kinds of organisms (Autotrophs) can perform photosynthesis while heterotrophs are organisms incapable of photosynthesis.
<u>Explanation:</u>
Photosynthesis is a mechanism used among plants as well as other species to transform energy from the sun into chemical energy which may be released later to power the functions of the species.
In autotrophs (organisms who self prepare there food ) with the support of a subsequent series of light-independent reactions like Calvin cycle, creates long-term energy collection in the form of sugars, while some bacteria use different mechanisms like the reverse Krebs cycle to accomplish the same purpose.
Heterotrophs are entities unable to photosynthesize and, by eating certain species, must therefore obtain energy and carbon from the food. In the term heterotroph: hetero means "other" while troph means "feeder", thus their food depends on other species.
The five proteins of the myofilaments are the following:
<span>1.
</span>Myosin, shaped like a golf club, with two
polypeptides intertwined to form a shaftlike tail and a double globular head,
or cross-bridge, projecting from it at an angle.
<span>2. </span>Fibrous actin is like a bead necklace—a string
of subunits called globular (G) actin. Each G actin has an active site that can
bind to the head of a myosin molecule.
<span>3. </span>Tropomyosin. It blocks the active sites of six
or seven G actins and prevents myosin cross-bridges from binding to them when a
muscle fiber is relaxed.
<span>4. </span>Troponin a smaller calcium-binding protein bound
to each tropomyosin molecule.
<span>5. </span>Titin (connectin), run through the core of a
thick filament, emerge from the end of it, and connect it to a structure called
the Z disc.
Answer:
anaphase, think a=apart and the chromosomes are being pulled apart
Answer:
20%
Explanation:
Your brain consumes about 20% of our daily intake of calories. That's about 400-500 calories for a man and 350-400 for a woman. Studies show that the brain is very metabolically active and will actually burn about 109 calories per pound of its mass per day.
