The questions has missed the multiple options. The options are as follows:
(a) organ, organ system, cellular, chemical, tissue, organismal; (b) chemical, cellular, tissue, organismal, organ, organ system; (c) chemical, cellular, tissue, organ, organ system, organismal; (d) organismal, organ system, organ, tissue, cellular, chemical.
Answer:
Option (c).
Explanation:
The evolution of the complex organisms take several billion years. The evolution of the organisms starts from the basic level and then move to the complex forms.
The hierarchy determines the level of the organization. Cell is the basic level of organization. The cells are formed by the union of chemicals. The cell combine together to form tissue. Tissue combines together to form the organ then the organ system and finally the whole organisms.
Thus, the correct answer is option (c).
Answer:
The correct answer is - cellular organization, tissue organization, organ level organization, organ system, and body.
Explanation:
The body of most of the organisms has several levels of the organization. The simplest level of the body organization is a cellular organization that includes cell and its components which are cell organelle that performs cellular level functions.
When there is an association of the two or more cells to perform a function is called tissue and this organization is tissue-level organization. Tissue join together to make an organ that performs a specific type of function.
Different organs combined together to form an organ system such as the digestive system or excretory system to perform a similar function. In the last these organ system form a body.
Thus, the correct answer is - cellular organization, tissue organization, organ level organization, organ system and body.

Answer:
a. satorius
Explanation:
The sartorius muscle is a two-joint muscle that moves both the hip and knee joints. Although anatomically considered a thigh extensor, its contraction actually causes a flexion of the hip joint. This is due to its location in the anterior (extensor) compartment of the thigh. Additionally, it is involved in abduction and external rotation of the hip joint.
In the knee joint, it forces an internal flexion and rotation. Flexion movement is the result of tendon insertion into the knee joint behind the flexor-extensor axis. When all five movements are performed simultaneously the legs cross in meditation position. Thus, the muscle is most easily palpable in this position.

The nurse needs to set the IV pump to provide 4 grams of magnesium sulfate over a 20-minute period to run the bolus.
Since the bolus comes diluted in 250 mL of normal saline, the nurse needs to calculate the rate at which the bolus will be delivered. To do this, the nurse needs to divide the amount of magnesium sulfate (4 grams) by the time it should take to deliver the bolus (20 minutes). This gives a rate of 0.2 grams per minute.
However, since IV pumps deliver in milliliters per hour, the nurse needs to convert this rate to mL/hr. To do this, the nurse multiplies 0.2 grams/minute by 60 minutes/hour, giving a rate of 12 mL/hour. Therefore, the nurse should set the IV pump to 12 mL/hour to provide the 4-gram magnesium sulfate bolus over 20 minutes.

The IV pump rate for a 4 gram bolus of magnesium sulfate to run over 20 minutes with a total volume of 250 mL should be set at 750 mL/hr.
To calculate the IV pump rate for a magnesium sulfate bolus of 4 grams to be administered over 20 minutes, we need to know the total volume of the IV fluid which is 250 mL.
Since the entire 250 mL should be administered in 20 minutes, we first convert minutes to hours because infusion pumps are calibrated in mL per hour. Thus, 20 minutes is ⅓ of an hour.
To find the infusion rate in mL/hour, we use the formula:
- Infusion rate (mL/hr) = Total volume (mL) / Time (hr)
- Infusion rate = 250 mL / (⅓ hr)
- Infusion rate = 250 mL / 0.333hr
- Infusion rate = 750 mL/hr
Therefore, the nurse should set the IV pump to run at a rate of 750 mL/hr to administer a 4 gram bolus of magnesium sulfate diluted in 250 mL of normal saline over 20 minutes.

Answer:
yes. i agree. early puberty leads to early stress, depression and early sexual behavior.
Explanation:
For young people who begin puberty earlier than their peers, the transformation appears to be particularly fraught, especially for girls. Early-maturing girls are at increased risk of a range of psycho social problems including depression and early sexual behavior.The average age of a girl's first period in the United States and Europe was about 16 a century ago. Today, it's closer to 13.In boys, puberty begins between ages 9 and 14, on average, starting with growth of the sexual organs and wrapping up with facial hair and a deepened voice.
Karen Rudolph, PhD, at the University of Illinois at Urbana Champaign, and colleagues, followed more than 160 boys and girls for three years. They found that girls who matured earlier than their peers had increased rates of depression that persisted over the course of the study. They also found that while early-maturing boys initially had lower levels of depression than later-maturing boys, over time they showed signs of increased anxiety, negative self-image and interpersonal stress. By the end of the three-year study period, the boys' rates of depression were almost as high as those of the early-maturing girls (Development and Psychopathology, 2014).

Answer:
Emulsification is a process where two liquids that do not mix are mixed, in digestion, it is the breaking down of fat globules in the duodenum into tiny droplets
Explanation:
The substance which performs emulsification is called bile
Bile is synthesized in the liver
Bile is stored and concentrated in the gallbladder
Once bile has been synthesized, it moves out of the liver through the hepatic ducts, the ducts (left and right) join to form the common hepatic duct which joins the duct from the gallbladder called the cystic duct. This bile duct enters the small intestine through a sphinter (Oddi) below the stomach.

Answer:
Calcium ions.
Explanation:
Calcium ions is stored in the sarcoplasmic reticulum of the muscle fibers. Calcium plays an important role in the muscle contraction.
Smooth muscles use calcium for the phosphorylation of myosin that couples the electrical excitation and initiates muscle contraction. The process of cross bridge cycle occurs in the muscle contraction.
Thus, the answer is calcium.

Answer:
Water-vapour molecules give of their heat to convert into liquid water which is absorbed by the surface on which they condense.
Explanation:
- Preventing condensation on the surface of a cold beer container will prevent the heat gain by the beer by absorbing the energy from the surrounding molecules of the water vapour present in the air in the form of humidity.
- When water vapour of the atmosphere which is present in the form of humidity condenses on the cold surface it releases the latent heat of vapourization to the cold surface of the container which is directly in contact with the beer which further absorbs the heat form the container.
- We know that the latent heat of vapourization of water is
. This amount of heat is very high and can lead to gain of temperature considerably.
Answer:
Water-vapour molecules give of their heat to convert into liquid water which is absorbed by the surface on which they condense.
