Contact [7]

Answer:

If bird song promotes an individual's ability to attract a mate and reproduce, then the song has an <u>     function</u>

<u />

Explanation:

Within a community, certain novel traits are fixed because they impart beneficial adaptations on an individual in their ecosystem (like mate attraction). Such modifications enable such individuals to live longer than their peers, and breed over time to produce more offspring who also exhibit these traits.

Natural selection takes place and is determined by the fitness of an individual , it contributes to evolutionary change as individuals with certain traits reproduce, the traits become fixed and prevalent within the population.

Describe the change which will occur if a piece of peeled potato is placed in a concentrated sugar solution and explain why this
skelet666 [1.2K]

Answer:

Through the process of Osmosis, water will move from a region of high water potential ('concentration') to low water potential. Therefore, water will slowly leave the cells of the potato and enter the sugar solution in an attempt to reach equilibrium and the potato will therefore lose mass.

11Alexandr11 [23.1K]

Answer:

The missing word is things.

However, the real question is how one material can serve so many purposes? That is what makes it possible for the spiders web to have a high "utility" value?

The answer is in how the spiders make the silk.

Explanation:

So it interesting to note that spiders do not make only one kind of silk. They vary depending on what purpose it's doing serve.

The most common type is Dragline Silk.

Dragline Silk: This contains spidroins. Spidroins fall under a category of a protein called scleroproteins. Because of its composition, a strand or fiber of Dragline has the same tensile strength as steel albeit more flexible. That is if one produced steel the diameter of a spider's silk, and compared both for strength, the silk will be stronger.

The spider produces Dragline silk in its silk glands where they are as viscous as a paste. From here is pulled out or extruded into lines of silk.

Other types of spider silk are:  

  1. Capture-spiral silk. Also known as the Flagelliform, they are used for securing lines of the web. They are adhesive, very elastic, and possess high tensile strength.  
  2. Tubiliform silk: They are also called Cylindriform. Its main use is for the protection of spider eggs. It is used to make a sac for which protects eggs. This type of silk is the toughest.
  3. Aciniform silk: For preserving fresh prey.  
  4. Minor-ampullate silk: This type is used by spiders for creating temporary support while they are spinning a web. Etc.
