8. The diagram below shows the shift in the spectrum for hydrogen light from several different sources in the universe.
What is the best argument that can be made from this data?
More distant galaxies are moving toward us faster.
More distant galaxies are brighter.
More distant galaxies are not as bright.
More distant galaxies are moving away faster.
Answers
Answer:
more distant galaxies are moving away faster.
the shift towards red (Doppler effect like with sound on Earth) is the indication.
Explanation:
what did this have to do with biology ?
and by the way, this is also something I debate severely in scientific communities, because yes, the red shift is there. but "more distant" also means "more in the past", so that the data shows us actually that things in the past moved faster away. not necessarily today ...

Los elefantes marinos del norte tienen poca variabilidad genética, probablemente, por un proceso que le hicieron pasar los hombres en la década de 1890. La caza hizo disminuir el censo poblacional hasta tan sólo 20 individuos a finales del siglo XIX. Desde entonces, su población ha «rebotado» hasta más de 30 000, pero sus genes todavía llevan las señales de sus aquellas generaciones su variabilidad genética es mucho menor que la de una población de elefantes marinos del sur que no sufrió una caza tan intensa. Este proceso puede denominarse como:

Use Darwin's theory of Natural Selection to explain the process by which the four-legged land animal, A, may have evolved, over about 20 million years, from the fish-like creature, C, in the swampy conditions of the time.
Answers
Answer:
Due to environmental conditions.
Explanation:
With the passage of time, environmental conditions change which causes the evolution of of four legged land animals from fish like creature. This change occurs due to change in environment. In water, there is no need for legs because fish moves with the help of fins and tail but the organisms that lives on land has legs in order to move from one place to another so we can say that change in the physical structure of organism occurs due to environment.

Interferons Interferons reduce macrophage chemotaxis to the infection. interfere with viral replication. prevent viruses from entering a cell. bind to viruses and destroy them. prevent viruses from leaving a cell.
Answers
Answer:
interfere with viral replication
Explanation:
Interferons (IFNs) are proteinous molecules, which are part of the innate immune system of our body. Interferons are produced in response to viral infections and they often specialize in preventing the virus pathogen from replicating or multiplying in the host cell.
As their name implies, INTERFERONS interfere with the replication of viral pathogens, hence, preventing the virus from further invading the host cell. This is done at the innate immunity level.

As population size approaches the carrying capacity of the environment, the intensity of density-dependent factors increases. For example, competition for resources, predation, and rates of infection increase with population density and can eventually limit population size.
