<span>The effect of insecticides will result in prolonged muscle contraction.</span> <span>Acetylcholinesterases are the enzymes that catalyze the breakdown of acetylcholine (Ach) in the synaptic cleft. This normally occurs, after the Ach achieves its effects on its receptors. On the other hand, acetylcholinesterase inhibitors inhibits the acetylcholinesterase enzyme thereby increasing the level and duration of action of the neurotransmitter ACh. Acetylcholinesterase inhibitors are used as insecticides.</span>
The dimensions of the room is not given. Lets assume a value and calculate BTU accordingly.
Answer and Explanation:
BTU, or British Thermal Unit, is defined as the amount of heat required to raise the temperature of 1 pound of water by 1° F.
In other words,BTU's measures the amount of heat an AC (or any other cooling unit) can remove from a room per hour. Higher the BTU, the more powerful the cooling.
Calculation:
Lets assume that a room is 10 feet wide and 14 feet long.
Calculate the size of the room by multiplying the height of the room with its width:
size of the room= 10 × 14
= 140 square feet
Then multiply the size of the room that you obtained in step 1 with 20 BTU per square foot, in order to get the minimum BTU's required for AC to cool a room,
140 × 20= 2800
2800 BTU cooling capacity is required.
B, Gases. The gases create an insulation around the planet so it keeps in heat from heat sources.
Answer:
1. Transverse foramina present: Cervical
2. No canals or foramen present. It articulates superiorly with the sacrum: Coccyx
3. Receive the most stress: Lumbar
4. Attach to ribs: Thoracic
5. Articulates with hip bones of the pelvis: Sacrum
Explanation:
The vertebral column is a <u>series of 33 bones called vertebrae</u> that play a key role in organ protection, movement of body, and overall support. The column has been divided into <u>5 different regions</u> with the number of bones.
<u><em>1. Cervical Vertebrate</em></u><u>:</u> These are the group of <u>seven vertebrae of the neck</u>, start immediately below the skull. Two cervical bones C1 and C2 are unique in function. They are responsible for the movement of the head. They have <u>transverse foramina</u> which <u>gives passage to vertebral artery and vein</u>.
<em><u>2. Thoracic Vertebrae:</u></em> They are a group of twelve small bones that form the vertebral spine in the upper trunk. The function of the thoracic vertebrae is to articulate with ribs to produce the bony thorax.
<em><u>3. Lumbar Vertebrae: </u></em>This is the largest segment of the vertebral column that consists of 5 bones between the rib cage and pelvis. They <u>carry all of the upper body weight</u> providing flexibility and movement to the trunk region. This is why it can <u>receive the most stress easily</u>.
<em><u>4. Sacrum Vertebrae: </u></em>There are 5 sacral vertebral fused bones. It <u>connects to the hip bones and play role in forming a strong pelvis</u>.
<em><u>5. coccyx Vertebrae:</u></em> These are a group of 4 fused bone. There is <u>no vertebral canal due to a lack of vertebral arches</u>. They <u>provide </u>an <u>attachment site for muscles</u> ligament and tendons. They also <u>play a role in stabilization and support</u> while sitting.
