Which organism is a secondary consumer (3rd trophic level)? a. larvae b. copepods c. killifish d. snapper

Biology
1 answer:
anygoal [31]3 years ago
5 0

ANSWER:  B, killifish

REASONING: A secondary consumer consumes animals that eat only plants.  Larvae and copepods do not fit these descriptions, because they do not eat animals.  Snapper do eat animals, so do not fit the description either.  Killifish eat small animals that do eat plants.

Can you kill brain cells by holding your breath for a minute
vitfil [10]
Yes it can kill brain cells. if you hold your breath for a short amount of time example 10 seconds it won't do any harm. but if you hold your breath for an extended time like a minute the cells will not get enough oxygen and eventually die. I hope I helped you

Zielflug [23.3K]

Answer:

Advanced forms of life existed on earth at least 3.55 billion years ago. In rocks of that age, fossilized imprints have been found of bacteria that look uncannily like cyanobacteria, the most highly evolved photosynthetic organisms present in the world today. Carbon deposits enriched in the lighter carbon-12 isotope over the heavier carbon-13 isotope-a sign of biological carbon assimilation-attest to an even older age. On the other hand, it is believed that our young planet, still in the throes of volcanic eruptions and battered by falling comets and asteroids, remained inhospitable to life for about half a billion years after its birth, together with the rest of the solar system, some 4.55 billion years ago. This leaves a window of perhaps 200-300 million years for the appearance of life on earth.

divine interventionThis duration was once considered too short for the emergence of something as complex as a living cell. Hence suggestions were made that germs of life may have come to earth from outer space with cometary dust or even, as proposed by Francis Crick of DNA double-helix fame, on a spaceship sent out by some distant civilization. No evidence in support of these proposals has yet been obtained. Meanwhile the reason for making them has largely disappeared. It is now generally agreed that if life arose spontaneously by natural processes-a necessary assumption if we wish to remain within the realm of science-it must have arisen fairly quickly, more in a matter of millennia or centuries, perhaps even less, than in millions of years. Even if life came from elsewhere, we would still have to account for its first development. Thus we might as well assume that life started on earth.

How this momentous event happened is still highly conjectural, though no longer purely speculative. The clues come from the earth, from outer space, from laboratory experiments, and, especially, from life itself. The history of life on earth is written in the cells and molecules of existing organisms. Thanks to the advances of cell biology, biochemistry and molecular biology, scientists are becoming increasingly adept at reading the text.

An important rule in this exercise is to reconstruct the earliest events in life's history without assuming they proceeded with the benefit of foresight. Every step must be accounted for in terms of antecedent and concomitant events. Each must stand on its own and cannot be viewed as a preparation for things to come. Any hint of teleology must be avoided.

Abundant and powdery pollen produced by small, indistinct flowers is probably transported by:
d1i1m1o1n [39]

Answer:

Wind

Explanation:

Commonly, a flower that uses wind as dispersion, tend to be:

Small

White of light colors

Produces a lot of pollen

Inconspicuous or indistinct

The reason behan the reason behind that is that they don't need to attract attention, they just need the wind to get rid of the flower and thus achieve propagation.
