Answer:
<em>Like every other organism the population size of the humans have increased over time.</em>
Explanation:
With the improvements in science and technology, life becomes better and better for human beings. In the past, when there were no discoveries for curing diseases, the human population declined because of the spread of various diseases and famine conditions.
But as the developments in the scientific world are made, it has been easier to cure diseases and other problems. As a result, the population size of the human goes on increasing.
<u>Answer:</u>
The sun’s spectrum though not a continuous spectrum allows us to represent the visible radiation. The spectrum from the sun has missing parts because the lights gets absorbed and not because of the sun.
Continuous spectra are discharged by any article that emanates heat. The light is spread out into a consistent band with each wavelength having some measure of radiation. For instance, when daylight is gone through a crystal, the light is spread out into it's colors.
When light passes through the sun’s atmosphere the spectrum is absorbed. The sun’s spectrum consists of seven colors VIBGYOR. When sun’s rays fall into the prism they are disbursed into seven colors.
Complete question:
Comparisons of amino acid sequences can shed light on the evolutionary divergence of related species. If you were comparing two living species, would you expect all proteins to show the same degree of divergence? Select the two correct statements.
- All proteins will show the same degree of divergence because they are modified with the same rate of evolution.
- All proteins will show the same degree of divergence because different species experience the same selection pressure.
- All proteins will show different degrees of divergence because different species live in different habitats and experience different selection pressure.
- All proteins will show different degrees of divergence because different species exhibit different patterns of behavior and have different metabolic pathways.
- All proteins will show the same degree of divergence because all cellular functions are essential to the survival of the organism.
- All proteins will show different degrees of divergence because some cellular functions are more essential than others to the survival of the organism.
Answer:
3) All proteins will show different degrees of divergence because different species live in different habitats and experience different selection pressure.
4) All proteins will show different degrees of divergence because different species exhibit different patterns of behavior and have different metabolic pathways.
Explanation:
- All proteins will show the same degree of divergence because they are modified with the same rate of evolution. FALSE.
- All proteins will show the same degree of divergence because different species experience the same selection pressure. FALSE
- All proteins will show different degrees of divergence because different species live in different habitats and experience different selection pressure. TRUE
- All proteins will show different degrees of divergence because different species exhibit different patterns of behavior and have different metabolic pathways. TRUE
- All proteins will show the same degree of divergence because all cellular functions are essential to the survival of the organism. FALSE
- All proteins will show different degrees of divergence because some cellular functions are more essential than others to the survival of the organism. FALSE.
In this example, we are comparing different species, although we do not know how different they are. Changes in the proteins reflect the divergence between groups during evolution. Among different animals and plants, changes in proteins and their following maintenance can be associated with a group divergence and evolution.
The same proteins amino acid sequences in different species provide information about the divergence point between both species. Probably, the origin of genes and protein changes and the subsequent fixation of those changes by natural selection is the cause of most of the phenotypic variation observed between species. So, genes and proteins are subdued to selective pressures that vary according to the environment and the species.
In populations of the same species inhabiting different places with different environmental characteristics suffer changes that respond to their life habits. Proteins evolve in different degrees and take different routes, influenced by the selective pressures of the environment surrounding them. Ecological, behavioral, reproductive pressures, among others, vary between populations according to their own needs and produce changes that "model" the organisms when fixating. These changes are inherited generation after generation, leading to a divergence in the species.
