Answer:

Explanation: Renewable source are energy that is derived from the environment this include sun, wind. This energy have been utilized by many nations and companies for their activities. Fossil fuel is an example of non- renewable. The advantage of renewable energy include; It ability to be available all the time, they are renewed and always available this include sun, wind.

They are cost efficient this is because renewal of this energy is at no cost,they are available in the environment and can be channel for use.

They require no cost of transportation unlike other fossil fuel that will be moved from one place another and they are eco-friendly they do not bring fear of ozone layer depletion and green house gases.

In fast-twitch oxidative-glycolytic fibers, their rapid increases in force rely on the ________ activity where rapid relaxation
Kitty [74]

Answer:

1. myosin ATPase

2. Ca2+-ATPase

Explanation:

ATPase activity of myosin head hydrolysis ATP and energize the myosin head. The energized myosin head forms cross bridges to facilitate the power stroke of muscle contraction. The fast-twitch oxidative-glycolytic fibers have the ability to produce ATP by aerobic respiration.  

These fibers have the  ATPase in their myosin heads that hydrolyze ATP three to five times faster than the myosin ATPase in slow fibers. This ensures the faster speed of contraction of these fast-twitch muscle fibers.

During their relaxation, Ca2+ ATPase pumps the calcium ions back to the sarcoplasmic reticulum. As the level of Ca2+ ions in the sarcoplasm decreases, calcium ions are released from troponin. Tropomyosin is allowed to cover the myosin-binding sites on actin and the muscle fiber relaxes faster.

How would shoot and root growth be affected by a mutation that caused plants to lose the ability to polymerize glucose into star
Anastaziya [24]

Answer:

b) Lateral branch shoots would grow more horizontally and have less of a tendency to turn upward.

d) Lateral branch roots fully embedded in soil would grow randomly upward and downward.

e) Roots breaking the soil surface would grow upward.

Explanation:

Inside the amyloplasts of the common bean the starch granules resemble variously sized cotton balls stuffed into a balloon. Under normal circumstances amyloplasts do nothing more than sit on the bottom of special gravity-sensing cells. When a plant is knocked over, the amyloplasts slide from what was recently the bottom of the cell onto a formerly vertical wall. Somehow, this movement is sensed and relayed to cells that secrete the growth-regulating plant hormone auxin.

Since the plant has lost the ability to transform glucose into the granules. The plant can´t differentiate between up or down because gravity is what causes these granules to settle down.
