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.
Answer:
E. phytoplankton
Explanation:
Phytoplankton, tiny organisms that live in the ocean, are autotrophs.
I hope this helps!
Weight = mass x gravity
16.8 = mass x 10
I put 10 because gravity strength on earth is 10
Then rearrange
Mass = 16.8 / 10
Mass = 1.68 Kg
Answer:
UV radiation basically damages skin by transferring energy to molecules in your skin, such as DNA, fat, proteins, etc. These molecules, which are already in their proper arrangement, absorb this energy. If the molecules absorb enough energy, the bonds holding them together can break, forming a new shape completely. For a cell that already has been chugging along smoothly thanks to specific molecules with specific shapes doing specific jobs, this is a big deal and causes serious problems.
Explanation:
UV radiation damage to DNA is a particular problem. DNA is a huge molecule and actually quite fragile. When a molecule of DNA is present in a cell, it resembles a zipper: it has two strands, with each strand tightly bound to corresponding molecules on the opposite side, called bases.
Answer:
individuals that develop beneficial traits have a better chance of survival, and are then able to pass on their genes. Eventually, if enough of those genes are passed on, that gene will become more prominent within the population.
