Answer:
Complementary RNA (cRNA) is a copy of a strand of RNA that will bind to the appropriate region of the original molecule. If the original RNA stand had a base sequence of AUU, for example, the sequence of the cRNA strand would be UAA.
Hope it helps.
have a wonderful day!
Answer:
There are many types of evidence which support the theory of evolution such as comparative anatomy, fossil records, phylogenetic relationship, embryology et cetera
Comparative anatomy includes homologous organs and analogous organs. They support divergent and convergent evolution respectively.
For example, the homologous structure of limb of humans, birds, bat, horse, whale et cetera show that they are made up of the same set of bones which are humerus, radius, ulna, carpals, metacarpals, and phalanges.
It shows divergent evolution and supports that these organisms have evolved from a common ancestor.
Embryological evidence: When early stages of embryological development of different organisms are compared, it is found that these stages are similar at different levels of development.
For example:
- The appearance of pharyngeal-arch (gill-like structures) in vertebrates during embryo development.
- Salamanders and terrestrial frogs pass through larval stages within an egg. They possess the features similar to aquatic larvae, however, when they hatched out the eggs being ready for life on land.

Answer:
Reduce genetic diversity
Explanation:
Genetic diversity is an extremely important factor when it comes to evolution. The more diversity and variation there is within a population, the more chances a species has of surviving.
In the case of inbreeding, organisms that are related are selected to mate. This has extremely negative effects on the species such as bad health and infertility issues. In addition, because they all share the same alleles, it results in a decrease in genetic diversity, augmenting the chances of the species to disappear.
This occurs because if, for example, there is an organism that possesses a capability to resist extreme weather conditions and another that does not have this trait, there are still chances to survive, whereas if they are all the same and none of them possess this capability, the probability of this species to go extinct is higher.
