Answer:
the overlapping decreases between the thin and thick filaments.
Explanation:
When w extend our hand or arm to the full and try to lift any heavy object, we are unable to lift the object inspite of applying all our force. We struggle hard to lift the object with our fully extended arm because when we extend our arm fully it decreases the overlapping of our thin and the thick filaments of our muscles which makes it difficult to lift. In other words, the resting length of our arm is the optimal length to generate force.
Vibrissae, more commonly known as whiskers, are sensory hair
that generally have a tactile sense, which is equivalent to skin. They grow on
most mammals except monotremes (duck-billed platypus and echidnas) and humans,
though humans still have remnants of the muscles once associated with vibrissae
in their upper lips. Vibrissae serve a number of purposes: such as sense of
touch; detection of danger, air and water currents, and movements of other
animals; and the locating of food.
The two jet streams that affect our weather in the continental US are the polar jets and the subtropical<span> jets. They are responsible for transporting weather systems that affect us. The polar front is the boundary between the cold North Pole air and the warm equatorial air</span>
The vascular cambium produces secondary phloem and xylem tissue.
Vascular cambium, a plant tissue located between the xylem and the phloem in the stem of a vascular plant. It is also the source of both secondary xylem growth and the secondary phloem growth. Vascular cambium is usually found on dicots and gymnosperms not on monocots which usually lack secondary growth. It does not transport water, dissolved food or minerals by plants.Vascular cambia are cylinders of unspecialized meristem cells which divide to make new cells which specialize to form secondary vascular tissues.<span> </span>
