Answer:
ATP
Explanation:
ATP is regarded as 'root of energetics' for living organisms. So, the organisms utilizes ATP to transport material and eliminate wastes from the body. Not only these functions are carried out by ATP but also several others infact all energy requiring processes are carried out ATP. e.g. muscle movements, neurotransmission, heart beats and various chemical reactions in the body all are carried out with the help of ATP.
In animals ATP is produced from the breakdown of glucose in the cellular respiration, glucose is obtained from the diet we take in. In plants ATP is generated from the process of photosynthesis. The source of energy within ATP is phosphate bonds, the breakdown of one phosphate bond while conversion of ATP into ADP produces or releases 30.6 KJ/mole of energy.
Answer:
A dorsal root (sensory or afferent) and a ventral root (motor or efferent) originate from the medulla. They unite near the intervertebral foramen, forming the spinal nerve. The nerves emerge from the intervertebral foramen, dividing into ventral and dorsal ramus.
Explanation:
The nerve is a set of nerve fibers perceptible to the naked eye and wrapped in connective tissue. They are made up of roots, trunks and nerve branches (some of them come together and form plexuses).The spinal nerve originate from the spinal cord in the form of 31 pairs: 8 cervical, 12 thoracic, 5 lumbar, 5 sacral and 1 coccygeal. They emerge from the spinal cord through two roots: dorsal roots, made up of sensory fibers that come from the sensory neurons of the spinal ganglion and that penetrate the spinal cord through the posterolateral and ventral root, made up of motor fibers, coming from the motor neurons of the anterior horn and visceral of the lateral horn of the gray matter of the spinal cord. This root exits the spinal cord through the anterolateral groove, then joins the posterior root to form the spinal nerve, which exits the vertebral canal through the corresponding intervertebral foramen.Each spinal nerve, after leaving the vertebral canal, emits two primary ramus: the dorsal ramus, contains somatic and visceral fibers that go to the skin and muscles of the back and the ventral ramus, which supplies the ventrolateral surface of the skin, body wall and extremities.
Answer:
Below is a definition of the distinction between mitosis as well as meiosis.
Explanation:
<u>Mitosis:</u>
- The genetic information (DNA) in something like a cell throughout mitosis has been duplicated as well as split evenly into two cells.
- An orderly sequence of circumstances known as the cell cycle moves through it's dividing cell.
<u>Meiosis:</u>
- Meiosis seems to be the mechanism whereby the gametes throughout sexually reproducing individuals are produced.
- Gametes have been formed in gender gonads and just like the new cells, constitute two complete sets of chromosomes.
Adrenaline helps in emergency situation by providing energy so that the major muscles of the body can respond to the perceived threat.
In danger, the brain then sends nerve impulses to the adrenal gland in the kidneys. When the nerve signal reaches the adrenal gland, chromaffin cells, in the medulla of the adrenal gland, release epinephrine or adrenaline. It then enters the bloodstream. It is thus carried around the body to cells in various locations, where it initiates several responses.
1. Adrenaline, along with another hormone called glucagon, is responsible for the breakdown of glycogen in liver cells. Glycogen is a form of energy storage. This gives energy to the muscles
2. Adrenaline effects the skin also. Restriction of the arteries is caused by the binding of epinephrine/adrenaline to some alpha-adrenergic receptors. This cuts off blood supply to the skin. This results in the contraction of the smooth muscle cells in the skin, which cause the raising of the hairs on the surface of the skin.
3. The lungs contain smooth muscle. Epinephrine causes smooth muscles to relax. Specifically, epinephrine binds to beta-2-adrenergic receptors on bronchiole muscle cells. This allows the bronchioles to relax, which enables intensified respiration.
<span>4. Adrenaline binds to beta-adrenergic receptors on heart muscle cells. This causes the contraction rate of the heart to increase. This ultimately leads to increased blood supply to the tissues in the body.</span>
The statement that describes an environmental consequence of sustainable land use is ; If commons are protected environmental issues could move to other areas ( D )
Sustainable land use act ensure the appropriate distribution of land resources such as land, water and other biodiversity in the environment, among the competing bodies in the environment. when land use is restricted/protected from indiscriminate usage the level of land pollution will be reduced as well which is a positive effect and not a consequence. other options listed are not environmental consequences because they do not impact the environment negatively
The consequence ( negative effect ) of sustainable land use is that the environmental issues prevented by this act could be moved to other areas that are not protected.
Hence we can conclude that the environmental consequence of sustainable land use is If commons are protected environmental issues could move to other areas.
