Answer:
Long protein filaments called kinetochore microtubules extended from poles on either end of the cell and attached to the kinetochores. During metaphase, the kinetochore microtubules pull the sister chromatids back and forth until they align along the equator of the cell, called the equatorial plane.
Explanation:
The correct option is (a) 2 → 4 → 1 → 3
A change occurs in the environment. → Poorly adapted individuals have decreased survivorship. → Well-adapted individuals leave more offspring than do poorly adapted individuals. → Genetic frequencies within the population change.
<h3>
What is genetic variation in population?</h3>
- The presence of various alleles, or different gene versions, within a population indicates genetic variety.
- If there is genetic variation, then everybody in the population will have various genotypes depending on the alleles they carry.
- Genetic loci that have many alleles are said to be polymorphic. Human characteristics like blood type and eye color, for instance, are polymorphic.

Answer:</h2>
Settlement can be directly turned into <u>sedimentary rocks</u>.
<h2>
Explanation:</h2>
Sedimentary rocks are kinds of rocks that are framed by the collection or statement of little particles and ensuing cementation of mineral or natural particles on the sea floor or other places on the earth's crust. Sedimentation is the aggregate name for procedures that reason these particles to settle set up.
The particles that structure a sedimentary shake are called residue and might be made out of geographical or natural debris.
