Forces on an object are combined yo determine the net force on that object.

if two forces are acting on a object in the same object the net force is the sum of both of them

if two forces are acting on an object in different directions they are subtracted

in the photo above the net force is 3

Ulleksa [173]

<u>W</u><u>hy does facilitated diffusion happen</u><u>:</u>

<em>~</em><em> </em><em>I</em><em>t regulates what goes in and what goes out of the cell</em>

<em> </em><em>~</em><em>T</em><em>he cell membrane is permeable to only a select few types of molecules</em><em> </em><em>and</em><em> </em><em>t</em><em>h</em><em>e molecules that are allowed to move across the cell membrane must be non-polar molecules which are small in size</em>

<em>~</em><em>F</em><em>rom one side of the membrane where the substrate concentration is high to the other side of the membrane where the concentration is lower</em>

<em>~</em><em>D</em><em>iffuses across membranes down the concentration gradient</em>

A partir del concepto de osmorregulación cual es la regulación hídrica y salinas en peces de agua dulce y salada
maks197457 [2]

Answer:

Absorben o excretan agua salada para mantener la homeostasis.

Explicación:

La regulación hídrica y salina en peces de agua dulce y salada se realiza según las condiciones ambientales. Los peces pueden pasar mucha orina muy diluida en la que hay menos solutos o sales, y logran el equilibrio de electrolitos en el cuerpo mediante el transporte activo de sales a través de las branquias. En un ambiente marino hipertónico, los peces de agua salada comienzan a beber agua de mar y mantienen el equilibrio electrolítico mientras excretan el exceso de sales a través de sus branquias y su orina.

Somatic hypermutation occurs only in the ________ regions of rearranged heavy and light chains.
babunello [35]

somatic hypermutation occurs only in the <u>V or Variable</u> regions of rearranged heavy and light chains.

Somatic hypermutation occurs only in activated B cells, not T cells. This occurs in germinal establishments inside of lymph nodes and the spleen, where B cells are stimulated and T cells are present. Somatic hypermutation is a procedure in which point mutations pile up at rates 106-fold greater than the background mutation rates observed in other genes in the antibody V-regions of both the light and heavy chains.

Somatic hypermutation of immunoglobulin (Ig) genes is important in antibody-mediated immunity. SHM in B cells serves as the molecular foundation for antibody affinity maturation. In this way, SHM plays an important role in optimizing antibody-dependent immune responses.
