The right answer is The texture.
In petrography, the texture (sometimes called structure) of a rock characterizes the arrangement of the crystals between them at the scale of the sample, the thin slice or even on a finer scale.
Texture is a characteristic determined by the size, shape and disposition of minerals in a rock that is observed at the microscopic scale. It allows to build the relationship between these characteristics and the conditions of formation of a rock (especially in the case of magmatic rocks, the rate of cooling).
Answer:
<h2>Meiosis I</h2>
Explanation:
1. Meiosis (meiosis I and meiosis II) produce four daughter cells from a single cell, each daughter cell contains half the number of chromosomes as compared to parental cell.
2. Meiosis have two cycles , i) meiosis I and ii) meiosis II.
3. In meiosis I, chromosomes first go replication and become double. It is the first step (meiosis I) that generates genetic diversity. During prophase I of meiosis I, homologous chromosomes pair and form synapses, a special step of meiosis.
4. There is crossing over in meiosis I which produce genetic diversity.
5. The four cells produced from a single cell become genetically different due to crossing occur which occur in meiosis I.
Answer:
Within the past 50 years, there has been a significant temperature increase on the Earth. Our world is getting dangerously warmer. Is it because of global warming? Some people, the climate change doubters, say there is no such thing. However, if you look at all the facts, you can clearly see that the temperature is rising. Humans are the reason for global warming and the temperature increase of the world.
Many genes make up one chromosome. 46 chromosomes make 23 chromosome pairs. There are 23 pairs of chromosomes inside of a nucleus of a cell. Many skin cells make up skin.
