Answer:
answer from google: ( see explanation )
Explanation: During the first stage of meiosis, the HOMOLOGUES (1-23) are segregated into different cells, resulting in 2 cells that each have 1 copy of each of the 23 chromosomes (still duplicated from DNA replication).
<h2>Answer:</h2><h3>the majority of blood volume consist of PLASMA.</h3>
The linear/ sequential search algorithm is not adequate for searching though large arrays
Hope this helps!
Answer:
Prophase 1
Explanation:
Prophase I :It can be divided into five stages:
1)Leplotene: In this stage, chromosome becomes visible and shorten as a single structure.
2)Zygotene: Homologous / sister chromosome pair up. This process is known as synapse. Synapse is the process of attachment of homologous /sister chromosome. One pair comes from the male parent while the other comes from the female parent.
3)Pachytene: Bivalents shorten.
4)Diplotene:Point of attachment of non-sister chromatids. The two chromosomes are seen to be joined at several points along their length. These points are known as Chiasmata.(Chiasmata, a cross). The paternal gene A, B, C may swap for the maternal gene a, b, c for instance, leading to a new gene combination in the resulting chromatids. This is referred to as *CROSSING OVER*.
5)Diakenesis: Homologous centromere move apart.
So, crossing over occurs in *Prophase 1.
Answer;
-The rate of the reaction;
The presence of an enzyme affects only the rate of the reaction.
Explanation;
-Enzymes are biological catalysts. Catalysts lower the activation energy for reactions. The lower the activation energy for a reaction, the faster the rate. Thus enzymes speed up reactions by lowering activation energy.
-Additionally, the rate of a chemical reaction increases as the substrate concentration increases. Enzymes can greatly speed up the rate of a reaction. However, enzymes become saturated when the substrate concentration is high.
