Answer:
True
Explanation:
Chiasma is the site of crossing over. It is an X-shaped site that appears in a tetrad (bivalent) chromosome during the diplotene stage of prophase I of meiosis I. Crossing over refers to the exchange of segments of chromatids and occurs between homologous chromosomes only. Crossing over is the event of prophase I of meiosis I and produce new gene combinations.
The homologous chromosomes are separated from each other but remain attached at chiasmata. The dissolution of chiasmata occurs by the end of prophase I and separates the homologous chromosomes completely from each other. Crossing over does not occur in mitosis. Since mitosis does not include crossing over, chiasmata are also not formed in mitosis.
- keystone species is the correct answer.
<u>keystone species</u> which keeps the number of other animal population in
control and low in the entire ecosystem. They play an important role
through this process and helps the food chain effectively.
dominant species - most common species; found often in the ecosystem.
invasive species - which fights for itself survival and can cause harm to
ecosystem. non-native to an ecosystem
False that is not correct
Picture 1 depicts convergent boundary.
Picture 2 depicts divergent boundary.
Picture 3 depicts transform boundary.
<h3>What is a Divergent boundary?</h3>
This occurs when two tectonic plates move away from each other while convergent boundary occurs when the plates collide with each other.
Transform boundary is a fault along a plate boundary where the motion is mostly horizontal.

A. Skeletal and muscular
the other three don’t have to do with this type of internal movement though as the abdominal region and internal organs don’t have to do with this, A is the only possible answer
