Answer:
change in a population through genetic variation over time
Explanation:
Answer: She called it a rhizome because a rhizome has nodes and inter nodes and is a modified stem that helps in propagation of the plant.
Explanation:
The roots of irises plant is called as rhizome because it has nodes and inter nodes. They have the ability to run inside the ground in a horizontal way.
As it is a stem it contains nodes and inter nodes in it. The nodes of the stem contains the axillary buds.
It is different from normal roots in the respect that normal roots does not contains nodes and inter nodes.
When raisins are placed in water and sit overnight, endosmosis takes place. Water goes into the raisins from the surrounding. Due to this endismosis, the raisins gain water and become larger in volume.
Since raisins absorbed some water, the volume of water from the container decreases.
<h3><u>Answer;</u></h3>
The above statement is <u>False </u>
<h3><u>Explanation;</u></h3>
- Speciation is an evolutionary process in which new species arise. There are three types of speciation, namely; sympatric, parapatric and allopatric speciation.
- <em><u>Sympatric speciation is a pattern in which speciation occurs in the absence of a physical barrier to gene flow; ex. polyploidy arising in flowers.</u></em>
- In an Allopatric speciation on the other hand, a physical barrier arises and separates two populations, ending gene flow between them and allowing reproductive isolating mechanisms to evolve so that later if the two groups come back into contact they will no longer be able to reproduce together, therefore making them different species.

Explanation:
Long bones are those that are longer than they are wide. The end of the long bone is the epiphysis and the shaft is the diaphysis. When human finishes growing these parts fuse together. The outside of the flat bone consists of a layer of connective tissue called the periosteum
