It consist of integral proteins and trans-membrane proteins and peripheral proteins as well
Well, protein actually helps you BREATHE, helps BUILD your tissues, and also helps replicate more and more of your DNA . c:
Answer:
The correct answer would be "The percentage of dark brown sea lions will increase, and the percentage of light brown sea lions will decrease".
Natural selection refers to the natural phenomenon by which organisms which are better adapted to the changing environment tend to survive and reproduce more as compared to the organisms which are less adapted.
As aquatic environment make dark brown sea lions more reproductively successful thus, the offspring of dark brown sea lions would have better chances to reach the reproductive age.
Hence, with the percentage of dark brown sea lions would increase and that of light brown sea lions would decrease.
The nurse should advice the patient to avoid intake of fluids before the surgery. This is the most likely intervention technique that would help avoid intra-operative complications, reduce cerebral edema, and prevent postoperative vomiting. The nurse should also prescribe the proper medication to ensure that the patient won't encounter any further problems after the operation.
Observations
The first observation is overproduction. This means all species produce more offspring than will survive to become adults. Think of all the thousands of fish eggs produced each year. This means populations of species should be getting larger all the time, but they aren't, because there are mechanisms in place to curb population explosions, such as competition for food, predation, and disease. From this, Darwin was able to make a deduction: there is a struggle for existence. Many of those fish eggs are food for predators, who would not survive without them.
Darwin's second observation was variation. This means members of the same species show variation in characteristics. For example, zebras show variation in pattern and color of their stripes. Goldfish have gold scales, orange scales, or brown scales, or a mixture of all three.
Variation applies to all traits, even those essential for the survival of the individual organism. An eagle depends on excellent eyesight to locate prey, but it can still be born shortsighted. This means that variations are random and are not specific to any favorable adaptation.
The next observation, selection , means organisms that survive are more likely to reproduce and pass on favorable adaptations to their offspring than those with unfavorable adaptations. For example, height is an inheritable characteristic, and for the giraffe, having long necks (which added to their height) was reproductively advantageous. The taller giraffes were able to reach leaves in tall trees, which kept them alive longer, and able to reproduce, making them more reproductively fit than shorter giraffes who couldn't reach those leaves and died without reproducing.
The last observation Darwin made wasadaptation . This means that some traits are passed on to new generations and become common within the population, like the long neck of the giraffe. This doesn't happen overnight, it takes time for these traits to spread throughout a population.
So, what does this mean for natural selection and genetic diversity? Let's find out.
