This body fluid directly affects the proper functioning of cells. this is the structure of a feedback system that receives output from the control center. this is the structure of a feedback system that provides input to the control center. a condition not regulated by a negative feedback loop would be: this is a change in body function that can be measured objectively. in which cavity is the brain located? in which cavity are the lungs located? in which cavity is the stomach located? this cavity is inferior to the abdominopelvic cavity. which cavity would include the heart?

1. Interstitial fluid directly influences the proper functioning of cells.

2. Effector refers to the structure of a feedback system, which gets output from the control center.

3. Receptor refers to the structure of the feedback system, which donates input to the control center.

4. Childbirth refers to the condition not regulated by a negative feedback loop.

5. Sign refers to the change in the function of the body, which can be determined objectively.

6. The cranial cavity refers to the large, bean configured cavity occupying the majority of the upper skull where the brain is situated.

7. The thoracic cavity compries of the lungs and is located in the mediastinum.

8. The abdominal cavity is the region where stomach is located.

10. The pericardial cavity comprises the heart.

I have some doubt in Question no 9.

if the type of the food available changes, then the frequency of beak types will change, because birds with beaks more suited to the available food will be more successful over time.

water is a polar molecule. a chemical bond is a force of attraction between atoms or ions. bonds form when atoms share or transfer valence electrons. atoms form chemical bonds to achieve a full outer energy level, which is the most stable arrangement of electrons. so, false

explanation:

in h2o molecule, two water molecules are bonded by a hydrogen bond but the bond between two h - o bonds within a water molecule are covalent. the greater the electronegativity difference, the more ionic the bond is. bonds that are partly ionic are called polar covalent bonds. nonpolar covalent bonds, with equal sharing of the bond electrons, arise when the electronegativities of the two atoms are equal.
