Physical fitness is a medical term describing the effect of exercise on body systems and disease prevention. The body’s ability to function efficiently and effectiveness' it should contain health-related physical fitness and skill-related physical fitness. Physical fitness includes metabolic fitness and bone integrity. It is associated with person’s ability to resist hypokinetic diseases.

Optimal physical fitness is not possible without regular exercise.

"Now that you have come up with an equation that describes the relationship between amounts of different nucleotide bases in DNA

Dima020 [189]

Answer:

G - 21%

T - 29%

A - 29%

Explanation:

Nucleotide bases in DNA are complementary. Adenosine (A) binds to Thymine (T) while Cytosine (C) binds to Guanine (G). Hence the composition of A in DNA is the same as that of T; and that of C is the same as that of G.

From the information given, C is 21%

Therefore G is also 21% of the genome as C is bound to G, the therefore are the same proportion.

C and G make up 42% of the genome (that 21% + 21%).

The remaining 58% (100%-42%) is made up of A + T

Similarly the proportion of A is equal to that of T,

Hence A is 29% (half of 58%) and T is 29%.

Which of these describes the most common way that material is added to a continental shelf?

slavikrds [6]

Had to look for the missing options and here is my answer.

The one that gives the best description of the most common way how material is added to the continental shelf is this: "Deposition of continental sediments". This deposition includes biological, physical, and even chemical processes that occurred in a span of time. Hope this helps.

The two primary muscles used for breathing are the diaphragm and the:

denis23 [38]

Intercostal Muscles

The muscles of respiration are muscles that contribute to exhalation and inhalation by causing the contraction and expansion of the thoracic cavity. However, diaphragm is the main muscle of breathing while intercostal muscles is one of the most important muscles for respiration. Intercostal muscles function by manipulating the width of the rib cage and they are attached between the ribs.

An internal membrane system where lipid components of the cell membrane are assembled, along with proteins and other materials

MakcuM [25]

A. Lipid bilayer: the phospholipid bilayer is the membrane of a cell. The bilayer contains lipids, membrane proteins, cholesterol, receptors for various molecules, pumps to transport ions and solutes against the concentration gradient, and many other items necessary for a cell to function and work together with other cells.

b. Osmotic pressure: Osmosis is the flow of water across a semipermeable barrier from an area of low solute concentration to high solute concentration. Osmotic pressure is the lowest possible pressure to prevent this water movement.

c. Endoplasmic Reticulum: the Rough ER synthesizes proteins for use outside the cell. The Smooth ER produces lipids and some steroidal hormones.

A. Lipid Bilayer is therefore the correct answer. Osmotic pressure does not involve the various components of the cell membrane, and the ER's produce proteins and hormones. Therefore A is right.

Hope this helps! :) Let me know if you need a clarification.
