<h2>Asteroid impact and Dinosaur extinction. </h2>

Explanation:

The scientists suggest that when a sufficiently large asteroid or comet struck the earth surface, they might have caused dust particles to rise up in the atmosphere and form a thick covering on the earth blocking the sun rays.

The blocking of sun rays must have resulted in severe colds and plants failed to carry out photosynthesis. Since, the plant died out , the herbivores got extinct because of the lack of food.

The loss of herbivores resulted in shortage of food for carnivores, and the larger carnivores started feeding on the younger population of their own species. Day by day the population size diminished and the dinosaurs along with some other species of plants and animals got extinct.

zavuch27 [327]

Answer:

The correct answer is option D, that is, 27.

Explanation:

27 three-nucleotide codons would be possible when polynucleotide phosphorylase is supplemented to a solution of GTP, ATP, and UTP. As there are three nucleotides available, that is, guanine, adenine, and uracil and each codon comprise three nucleotides, thus, there would be a probability of (3)^3 codons, that is, 27.

Answer:

Apple tree and grass are producers, mushroom and bacteria are decomposers, and everything else are consumers. The bear is herbivore I believe, the rabbit is as well to my understanding. The pig is omnivore and lion is carnivore.

Explanation:

Starting with producers, most plants are producers. They photosynthesize to make their own food (glucose). Decomposers break things down like dead animals. Carnivores eat only meat, which is what a lion does. It eats no plants. The pig is an omnivore, meaning that it eats both meat AND plants. Lastly, the bear and rabbit are herbivores meaning that they only eat plants. I always remember it as "HERBivore which sounds like HERBS which are plants" Hope this helps!
