Answer:
<u>
They have hydrophilic heads and hydrophobic tails.</u>
Explanation:
Phospholipid membranes are comprised of a chain of lipids. These typically are arranged in a bilayer; the hydrophilic lipid heads are polar, and face outwards, while the hydrophobic tails are polar facing inwards.
The membranes are selectively permeable, and only allow the movement of small, non-polar molecules through the bilayer.
Answer:
Although the rat liver is typically lobated2 and its ap- pearance does not resemble that of the human liver, the hepatic lobes of the rat liver have been found to be equivalent to the sectors of the human liver. As rats and humans belong to the class Mammalia, similar em- bryological development is expected.
Answer:
The Rhizaria are supergroup species of mostly unicellular eukaryotes and classified as protista. Rhizaria include species like cercozoa, foraminifera and radiolaria.
<u>Some of the attributes of Rhizaria are:</u>
- non-photosynthethic in nature, but some have a symbiotic relationship with unicellular algae.
- express only rDNA sequences so they can vary in different forms.
- do not have clear morphological characters
- they mostly includes amoebas which functions for food engulfing and help to direct movement in rhizarian protista.
<u>Contribution of Rhizaria to the ecosystem:</u>
- There are known as abundant bacterial grazers, and play very important role in microbial food webs.
- They provide a wide diversity of marine organisms.
- important contributors to oceanic carbon pools .
Hence, Rhizaria are important part of ecosystem.
