Emotion is one of the responses of an organism (whole) which
involves physiological arousal. Other than indicating emotion, physiological
arousal or heightened physiological activity is modernly used in polygraphs.
Polygraphs or lie detector notes changes in blood pressure, pulse, respiration
while the subject is asked and answers questions. It is based on the assumption
that dishonest answers are indicated with physiological arousal.
The correct answer to your question is the last one; how species change over time.
Hope that helps!
Answer:
D
a buffer is an ionic compound that resists change in ph hence no ph change on addition of an acid proves the presence of a buffer which is different when distilled water is added because it is neutral hence no increase or decrease in ph
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.
The answer is <span>prokaryotic cell</span>
