Which of the following could be considered the most recent common ancestor of living tetrapods? a) a sturdy-finned, shallow-wate
tensa zangetsu [6.8K]

Answer:a) a sturdy-finned, shallow-water lobe-fin whose appendages had skeletal supports similar to those of terrestrial vertebrates.

Explanation:

An ancestor - An earlier type of a species at any distant time — a progenitor.

A tetrapod is any vertebrate with four limbs. It includes any vertebrate (such as birds or snakes) that have evolved from early tetrapods — especially all members of the superclass Tetrapoda.

The presence of bones that support the appendages in Lobe – fin fish were found to be similar to the categorical skeletal supports found in the limbs of sample tetrapods. The sub class crossopterygii includes the Lobe – fin fish, which is seen as one of the recent common ancestor of living tetrapod today.

Explique de que forma a obstrução dos vasos da planta hospedeira pelos biofilmes de bactérias pode levar à morte progressiva das
musickatia [10]

Answer:

Os biofilmes são uma comunidade complexa de microrganismos, que pode ser composta por uma única espécie ou uma combinação de espécies. Os biofilmes são geralmente formados nas superfícies de materiais não vivos ou nos tecidos de organismos vivos; que pode estar externamente nos tecidos vivos dos organismos ou dentro dos tecidos vivos do organismo. Quando os microrganismos formam um biofilme, aumentam suas chances de resistir a anticorpos produzidos pelo organismo e aumentam suas chances de colonização completa do organismo. Algumas doenças são caracterizadas pela presença de biofilmes, que são, na maioria dos casos, a causa da doença.

<em>No caso de obstrução de vasos de plantas hospedeiras por biofilmes bacterianos; os biofilmes se formam na superfície do vaso e aumentam gradualmente de tamanho até que haja uma obstrução completa do vaso da planta. Quando o vaso da planta é eventualmente obstruído, o fluxo de materiais e minerais necessários é obstruído; levando à obstrução das células da raiz de receber materiais vitais e minerais necessários para o crescimento, isso eventualmente leva à morte progressiva das células da raiz.</em>
