Answer:
dismissed the idea that species are constant and emphasized the importance of variation and change in populations
Explanation:
- Darwin and Wallace were the two scientists that contributed to the theory of evolution by natural selection.
- According to their ideas, the mechanisms that lead to evolution is natural selection.
- The idea for natural selection stems from the fact that the available resources are limited in nature and hence, there will be competition for survival and only the individuals that will have heritable traits that will favor their survival under such competition would be able to live and thus, produce more offsprings with similar traits and hence, this will lead to evolution.
- This theory of natural selection thus emphasized that the traits possessed by organisms are not constant but are variable and the populations constantly change over time.
Vestigal structures is the answer!!
Answer:
5= mRNA is “messenger” RNA. mRNA is synthesized in the nucleus using the nucleotide sequence of DNA as a template. This process requires nucleotide triphosphates as substrates and is catalyzed by the enzyme RNA polymerase II. The process of making mRNA from DNA is called transcription, and it occurs in the nucleus.
<u>Answer:</u>
Option(b)
European colonization influenced the lives of native peoples in the South Pacific by forcing them to give up their land to settlers.

</u>
Colonization refer to the acquiring of political control over a territory or region through tact or force. European colonization affected the lives of native people by introducing a fatal disease which wiped out a considerable number of the native population.
Alright, let's use Alka-Seltzer tablets as an example
These are made with ingredients like sodium bicarbonate. When you toss one int the water, the sodium bicarbonate splits apart in a chemical reaction and forms sodium and bicarbonate ions, separate. This releases a ton of CO2 bubbles really fast.
In order for this reaction to even HAPPEN, the sodium and bicarbonate ions have to come into contact with the hydrogen ions JSUT the right way, otherwise, the reaction might not happen. The variable that can influence this: temperature. The hotter the temperature, the faster the molecules heat up and start bouncing around, the colder the temperature, the longer it takes for the molecules to get to moving.
Using this info, you can form a hypothesis:
In chemical weathering, the hotter the temperature, the faster the reaction will take place, the lower the temperature, the longer the reaction will take.
Or you can use something along those lines.
