Organization of Cells
Biological organization exists at all levels in organisms. It can be seen at the smallest level, in the molecules that made up such things as DNA and proteins, to the largest level, in an organism such as a blue whale, the largest mammal on Earth. Similarly, single celled prokaryotes and eukaryotes show order in the way their cells are arranged. Single-celled organisms such as an amoeba are free-floating and independent-living. Their single-celled "bodies" are able to carry out all the processes of life, such as metabolism and respiration, without help from other cells. Some single-celled organisms, such as bacteria, can group together and form a biofilm. A biofilm is a large grouping of many bacteria that sticks to a surface and makes a protective coating over itself. Biofilms can show similarities to multicellular organisms. Division of labor is the process in which one group of cells does one job (such as making the "glue" that sticks the biofilm to the surface), while another group of cells does another job (such as taking in nutrients). Multicellular organisms carry out their life processes through division of labor. They have specialized cells that do specific jobs. However, biofilms are not considered multicellular organisms and are instead called colonial organisms. The difference between a multicellular organism and a colonial organism is that individual organisms from a colony or biofilm can, if separated, survive on their own, while cells from a multicellular organism (e.g., liver cells) cannot.

Smaller muscle groups with a similar functional ability might include the ____________ major which acts as synergist in producin
Oksanka [162]

Answer:

Smaller muscle groups with a similar functional ability might include the antagonist major which acts as synergist in producing the same action as the agonist.

example : the biceps and triceps muscles of arm, work together as agonist and antagonist respectively.

The biceps helps to lift up or flexes the forearm and the triceps helps to extend it.

Explanation:

many muscles work together to make an action happen.

the muscle who is involved in an action principally, is known as prime mover or Agonist muscle.

Antagonist muscle does the opposite action  of the agonist muscle.

antagonist also helps in-

  1. maintaining the body posture or position.
  2. controls the rapid movements.

like, to move a bone , the muscles attached to it work together to make a movement happen. like- to lift up a arm, agonist or prime mover muscles helps to lift up or flex the arm and the antagonist or synergist muscle helps to extend it.

3. Hailey, a local registered dietitian, frequently joins Aaron during his cooking classes at the local community hospital.
slega [8]

Answer:

Hailey, a local registered dietitian, frequently joins Aaron during his cooking classes at the local community hospital.  Hailey often points out the common food sources of soluble fiber during Aaron's one hour cooking class. When  working with patients and their families in their hospital rooms, she often explains to how common foods containing  soluble fiber can play a major role in reducing the risk of having another heart attack. For this evening's cooking  class, Hailey set up a display of five common items on a table and asked for a volunteer to select the ones which  provide soluble fiber. During the cooking class, Jeff offered to try his hand at choosing the items which provide  soluble fiber. Jeff should select all of the following items except:

canola oil

Explanation:

Canola oil contains fatty acid rather than fiber which Jeff is looking for among the food staples presented to him
