Biology

MAVERICK [17]3 years ago
8 0

Answer:

Individual lipid and protein molecules of the cell membrane are free to move laterally  in the plane of the membrane.

Explanation:

Cell membrane is the lipid bilayer made of two layer of phospholipids in which proteins are embedded. The cell membrane is fluid because most of the interactions among proteins and lipids as well as between various phospholipids molecules of the membrane are non-covalent. These interactions allow the individual lipid and protein molecules free to move laterally in the plane of the membrane.

What is Noah's principle?
Karo-lina-s [1.5K]
Noah's principle is a concept that comes from the Biblical story found in the old testament where God gave Noah instructions to build an ark to save him and his family . The concept here is that God did not tell Noah when it was going to rain. The people of the day most probably mocked and derided Noah as a time waster or a fool. That is, until the flood came. The " fool" had been wiser all along. An Application is this. Google gives everyone who does online business "suggestions" and "guidelines" but not everyone chooses to listen. Google rarely, if ever, tells us when they will put the guidelines into action. Panda, a Google ranking system, took 6 years while Google was telling online users to follow certain guidelines. Many ignored, until Panda was put into action, and those who had not heeded suffered with only themselves to blame. Moral: Heed and prepare even if the outcome tarries.

What evidence suggests that vertebrates are more closely related to echinoderms than are any other invertebrate phyla?
VMariaS [17]

Answer:

Option C, shared DNA sequences

Explanation:

Complete question -

What evidence suggests that vertebrates are more closely related to echinoderms than are any other invertebrate phyla?  

- shared patterns of development

- shared morphology

- shared DNA sequences

Solution

Vertebrates have true backbone while invertebrates lack true backbone. Among the invertebrates, the echinoderm phylum is closely related to vertebrates as the echinoderm possesses notochord (similar to backbone) during their early stage development which disappears later.  

Through the genomic sequence studies it has been found that echinoderms are similar to vertebrates in many ways. Echinoderms have diverged from deuterostomes along with human and hence pose some genetic similarity  which can be devised through study of common DNA sequences

Hence, option C is correct
