The lymphatic system has many functions in the human body. Here are the two main ones.

1.) the fat tissue in the body is transported through lymph tissue, part of the lymphatic system.

2.)the lymphatic system also has a significant role in the human defense system. After a pathogen (a disease causing substance eg. Bacteria) has bypassed the general defence system, its up to the lymphatic system to fight these infections.

It does this through the production of antibodies against these pathogens. Cells are produced to produce and antibodies, namely, b and t cells. Examples of these cells include; killer t cells(what it says on the tin.) memory b AND t cells memorise the pathogen so it does not infect you again(induced immunity). Suppressor t cells stop killer cells from destroying normal healthy human cells. These particular cells have a significant role immunity.

Not 100% sure but I think the lymphatic system has a role in the production of phagocytes and monocytes which engulf the bacteria(as opposed to using chemicals to destroy them). Ps. Antibodies recognise pathogens through specific antigens on these harmful cells.

Finally, I believe the lymphatic system can be linked with white blood cells in the production of additional immunity proteins but you may have to do your own research on that!

GOOD LUCK

Ears

¿Qué es el oído y qué hace?

El oído consta de tres partes diferentes, que funcionan conjuntamente para captar sonidos y transmitírselos al cerebro: el oído externo, el oído medio y el oído interno.

El oído externo

El oído externo está formado por el pabellón auditivo (también conocido como "pabellón auricular" o "pabellón de la oreja") y el conducto auditivo. Los pabellones auditivos son las partes visibles que tenemos a ambos lados de la cabeza y están compuestos por cartílago duro cubierto de piel. La principal función del pabellón auditivo consiste en captar sonidos y conducirlos hacia el conducto auditivo, que conecta con el oído medio. Las glándulas de la piel que recubren el interior del conducto auditivo fabrican cera o cerumen, que protege este conducto, eliminado la suciedad y ayudando a prevenir posibles infecciones.

El oído medio

El oído medio es una cavidad llena de aire que transforma las ondas sonoras en vibraciones y las transmite al oído interno. El oído medio está separado del externo por el tímpano (o membrana timpánica), una fina lámina de tejido que va de lado a lado del conducto auditivo y que está fuertemente tensada sobre él. Los sonidos golpean el tímpano, haciendo que se mueva.

wariber [46]

Answer:

The correct answer would be - there will be wild type and double mutant (contains both the deletion mutation and the point mutation)

Explanation:

It is mention that the deletion mutation and point mutation are non-overlapping or no overlapping regions in the phage genome. A crossing-over event between the regions of these two mutations would get wild-type which means there would be neither point mutation nor deletion mutation and other would be a double mutant that contains both mutation - the point mutation and the deletion mutation.

Thus, the correct answer is - there will be wild type and double mutant (contains both the deletion mutation and the point mutation)

The correct answer is C.) Getting food. Unlike plants, which have the ability to produce enough food through photosynthesis, heterotrophs, which include all animals (Invertebrates are animals as well) must gain their food from outside sources. Hope this helped!
