Answer:
Ammonites, , Brachiopod, Grapolithina,Trilobites and Nanofossils are examples of index fossils
Explanation:
Ammonites were common during the Mesozoic Era (245 to 65 mya), but were not found after the Cretaceous period. They went extinct during the K-T extinction (65 mya)
Brachiopods which are mollusk-like marine animals appeared during the Cambrian (540 to 500 mya). Some types of them still survive
Grapolithina which are widespread colonial marine hemichordates that also lived during the Cambrian period.
Nanofossils are microscopic fossils which are remains of calcareous nannoplankton, coccolithophores from various eras
Trilobites were common during the Paleozoic Era (540 to 245 mya); about half of the Paleozoic fossils are Trilobites. Trilobites evolved at the beginning of the Paleozoic Era and went extinct somewhere in the late Permian period which was 248 million years ago
This might be extra information but i hope it helps
etc pls help
Answer:
C.
Explanation:
Because since it only changed one amino acid in the sequence there most likely won't be a noticeable change in the phenotype. Also through process of elimination you can rule out both A and D because there since the amino acid sequence has changed there will be a change to the genotype and B can be eliminated because there is not enough information to know the change of the one amino acid will cause a disease in the dog.
Answer:
The blonde hair would be the recessive trait and both the parents must be heterozygous dominant.
For instance, let us consider B and b the alleles of the gene responsible for the color of the hairs.
B is the dominant allele which codes for the brown color whereas b is recessive allele which codes for blonde hairs.
The phenotype of both the parents is a brown color, that is, dominant trait. They genotype would be Bb.
The cross would produce offspring with three possible types of genotypes BB, Bb, and bb in the ratio 1:2:1.
The offspring with BB and Bb genotype would have brown hair color and the offspring with bb would have blonde hair color.
tertiary consumers
(B) primary consumers, deer, bacteria, fungi, nonliving things, tertiary
consumers
(0
producers, primary consumers, secondary consumers, tertiary consumers
D primary producers, primary consumers, secondary consumers,
carbohydrates, water
Answer:
answer is (0, or the third option
Explanation:
D is wrong cause carbohydrates is health
Answer:
Both the symbiotic and the predator/prey relationships evolve together. For the symbiotic take the example of the bird on the rhino's back. They are both in the same environment so their relationship evolves (develops) together, helping each other out. The bird gets to eat the bugs on the rhino and the rhino is kept for being infested with bugs. In the predator/prey situation, think about the lion and antelope. The lion is the predator looking for food. The prey is what he eats. Only the fastest and most able-bodied lions are going to get the antelope. In order for the antelope to survive, it must become swifter and better able to conceal itself. The best of both animals will survive thus strengthening their blood lines. The difference between how the pairs evolve is their interaction. Symbiotic help each other; they don't do harm to one another. Predator/prey relationships is the opposite. The lion intends to do harm to the antelope. He needs the antelope for food.
