Describe the process by which coral polyps and algae create a coral reef.

1 answer:

3 0

Coral reefs are built by coral polyps as they secrete layers of calcium carbonate beneath their bodies. And inside each coral poly lives single-celled algae called zooxanthellae. So basically in simplistic terms, coral polys create coral reefs and algae is in coral polys which also goes into coral reefs when they are made.

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.

What role does the somatic nervous system play?

Afina-wow [57]

Answer:

b. It converts messages that are received from the central nervous system into involuntary reflexes.

Explanation:

The somatic nervous system (SNS) is part of the peripheral nervous system (SNP), which is responsible for transmitting motor and sensory information both back and forth to the central nervous system (CNS).

The main function of the somatic nervous system is to connect the central nervous system to the organs, muscles and skin. This allows us to perform complex movements and behaviors. Somatic neurons carry messages from the external areas of the body that are directly related to the senses. The information captured by the sensory systems is transmitted to the central nervous system. The CNS then sends signals through the nervous networks of the somatic system to the muscles and organs.

This suggests subclinical deficiency .

Subclinical deficiency is a condition in which a nutritional deficiency that is capable of having an effect on an individual’s health is not severe enough to produce typical deficiency signs and symptoms. Subclinical deficiency is discovered only by biochemical changes and it can change to clinical deficiency if it is not treated.
