Answer:
The correct answer is D
Explanation:
The cell membrane is essentially composed of the following:
- phospholipids
- cholesterol
- proteins
The phospholipid consists of a <em>hydrophilic </em>phosphate 'head' and the tail is the <em>hydrophobic</em> fatty acid chain.When cellular membranes form,phospholipids collect into two layers in light of these hydrophilic and hydrophobic properties. The phosphate heads in each layer face the fluid or watery condition on either side, and the tails conceal away from the water between the layers of heads, since they are hydrophobic.
There are 3 main factors that greatly influence the fluidity of the plasma membrane:
- temperature
- cholesterol
- saturated and unsaturated fatty acids
Answer:
Anthropoids lived for approximately 0.86% of the total time.
Explanation:
- Anthropoids are the higher developed organisms that includes apes and ape mans.
- The age of earth is 3500 million and anthropoids lived for about 30 million years.
- By the simple calculations we can find out the data in percent which gives us the result nearest to 0.86%.
- That means 0.86% of 3.5 billion year is equivalent to 30 million years (time that was lived by anthropoids).
Answer:
your gathering evidence but sorry if iam wrong ( colletiong data)
Explanation:
Glass - Glass can be used to gather evidence, for example collecting fingerprints or blood from a broken window; however, glass also has a place in the trace evidence section. Broken glass fragments can be very small and lodge in shoes, clothing, hair or skin. Gathering glass fragments from a crime scene can be valuable in determining end-use or connecting people and objects to places. For example, windshields have a different color and composition than a drinking glass or a lead crystal vase, so glass fragments on an individual’s clothing could be compared to those collected at a hit-and-run scene to determine if that individual was present.
