Answer:
A. The two proteins are very likely related evolutionarily.
B. The differences in the sequences in many instances represent a conservative change (such as L for I).
Explanation:
A. Humans and sperm whales are vertebrates and mammals, this implies that they have a common ancestor a long time ago, which makes them evolutionary related.
B. Conservation indicates that a sequence has been maintained by natural selection. This means that protein structure is not exactly the same but is quite similar.
Options C and D, contradict the above explanation, and they make no sense because sperm whales and humans share a common ancestor (mya).
A. is your answer
a. <span>radiant to thermal
see u later hailey :3</span>
This is false
Even though it might seem true, it's false because people often mix it with desert biome due to it's rigid and dry climate. However, the caparral biome has more rainfall, which is why there are many different plant species and trees, as well as animals.
Answer:
c. Spindle fibers
Explanation:
In eukaryotic cells, the centrioles are small sets of microtubules composed of tubulin proteins. Moreover, in animal cells, a centrosome is an organelle localized near the nucleus which contains a pair of centrioles. These organelles (centrosomes) are referred to as microtubule-organizing centers. During Anaphase, centrioles move to opposite sides in the cell in order to organize the spindle fibers and separate the chromosomes during cell division.
Humans can have very damaging effects on ecosystems. An example is if we cut down trees, not only does that disturb the vegetation and plant life, but it also disturbs the life of the animals who relied on those trees for food and shelter.
