Answer:
<em>Tiktaalik roseae</em>
Explanation:
The discovery of the fossil, <em>Tiktaalik roseae</em> on a Canadian island gives credence to the fact that animals moved from living in water to living on dry land. This fish which has feature of land animals such as a neck, skull, and ribs is believed to have lived some 375 million years ago. It also has features of fish such as the fins and scales.
The discovery of this fossil is important to scientists because it confirmed their believe that there should be an organism that would prove that life transitioned from water to land. The fossil was discovered in the year 2004.
Answer: The base pair rule for RNA is that adenine pairs with uracil, thymine pairs with adenine and cytosine pairs with guanine.
Explanation: RNA contains adenine, uracil, cytosine and guanine while DNA contains adenine, thymine, cytosine and guanine. Thymine is not found in RNA while uracil is not found in DNA. In RNA base pairing, Watson and Crick proposed a rule that wherever adenine is found in DNA, Uracil occurs in the complementary RNA strand, wherever thymine is found in the DNA strand, adenine is found in the complementary RNA strand and wherever guanine occurs in the DNA strand, cytosine is found in the complementary RNA strand.
I think it's D ^-^
If it's not then it is B
Answer:
The correct answer is - reducing competition between the birds for resources.
Explanation:
In this ecosystem, the two species of birds brown creepers and nuthatches share habitat in the same tree for their food resources are insects. Brown creepers feed on resources on the bottom of the tree whereas nuthatches feed on the top of the tree.
By this, they avoid competition between these two birds for the same food resources in the same tree. The competition would be more if both have depended on the insects all over the tree.
The correct answer is Axial Position
Reason:
When axial groups lie on the opposite sides of the ring, they are capable of holding large molecule and are stable as there is less steric hindrance between those groups. Also the molecular distance between them is large.
