Answer:
Explanation:
It is estimated that the Precambrian Era lasted between 3.9 and 4 billion years. Many scientists believe that this era accounts for 90 percent of the world's history.
Answer:
It will remain relatively stable
Explanation:
<u>The carrying capacity (k) of an environment is a factor that represents the maximum number of organisms of a particular species such environment can support based on the resources it has. </u>
<em>Below the carrying capacity</em>, the population of a species still has the potential to increase due to resource availability, and <em>above the carrying capacity</em>, the population has the potential to reduce due to the overstretching of the available resources. Factors that keep the population from expanding significantly beyond the carrying capacity include competition for resources, natural disasters, disease outbreaks, etc.
<em>Hence, if a population is steady at its carrying capacity and a group of organisms from that species moves into the same space occupied by the original population, the carrying capacity will only increase temporarily before factors such as competition and natural disasters operate to bring the carrying capacity to the normal level. </em>
Answer: alleles
Explanation:
Alleles are different forms of a given gene. Alleles are mutated forms of a given gene which controls a particular trait. For instance, the gene that codes for hemoglobin is denoted with the letter A but the gene has another variant denoted by S. In abnormal hemoglobin S (sickle hemoglobin), glutamate is replaced by valine at position 6 in the amino acid sequence of the two beta chains of hemoglobin. This change in the amino acid sequence causes the red blood cells to have a sickle shape resulting in sickle cell disease. Therefore hemoglobin A and S are alleles of a given gene.
Like repels like when we're working with electrical charges. So positive repels positive and negative repels negative. When you have questions that ask which of the following or which of these or something like that, it's best to give us those options so we can give you the best help possible.
