<u>Answer:</u>
Genetic disorder that can result when sister chromatids fail to separate properly is likely to occur in meta-phase (m-phase) because in mitosis during m-phase there is separation of DNA to two equal halves.
<u>Explanation:</u>
- Genetic disorder is the problem that is caused by the abnormal activities in gene.
- This is also called mutation which may cause due to error during replication of DNA and also due to some environmental factors such as radiation exposure, smokes.
- So, during meta-phase, genes might not separate and genetic disorder might happen.
The quiver tree faces various problems due to climate change and drought periods.
The population of this plant tries to avoid the unfavorable environmental conditions by shifting their growing range towards the poles, or more precisely away from the heat of the equator.
<h3><u>Answer;</u></h3>
primary ecological succession
A glacier retreats exposing bare rock and allowing communities of organisms such as moss and lichens to move in. This is an example of <u>primary ecological succession.</u>
<h3><u>Explanation</u>;</h3>
- Primary succession is a type of succession that occurs following an opening of a pristine habitat, for example, a lava flow, an area left from retreated glacier, or abandoned strip mine.
- <em><u>Primary succession occurs in lifeless area; that is regions in which soil is incapable of sustaining life.</u></em>
- <em><u>The first organisms to appear in areas of primary succession are often mosses or lichens, often known as pioneer species because they are the first species present.</u></em>
Incorrectly. Because he has no idea wether the ants do it out of fear or other emotion (I dont think ants have the mental capacity to process emotion). He does'nt observe the ants are in fear he infers or guesses that they are.
Answer:
Explanation:
An increase in length of the shoot and the root is termed to as primary growth of a plant. It occurs as a result of cell division in the apical meristem. Secondary growth is identified by an increase in thickness or girth of the plant caused by cell division in the cambia or lateral meristems.
1) apical meristem- primary growth
2) cork cambium - secondary growth
3) elongation - primary growth
4) provides structural support - secondary growth
5) increases exposure to light - primary growth
6) increases vascular flow - secondary growth
7) growth in thickness - secondary growth
8) occurs in plants that live many years - both primary and secondary growth
9) occurs in plants that live only one year - primary growth
10) lateral meristem - secondary growth
11) vascular cambium - secondary growth.
