During prophase I, all four chromatids of the two homologues become closely associated as a result of pairing, forming a structure known as a tetrad or bivalent.
<h3>What is a tetrad?</h3>
A tetrad is a structure formed during the prophase I stage of meiosis I whereby two homologous chromosomes pair together.
Meiosis occurs in two stages of division namely;
- meiosis I
- meiosis II
In meiosis I, homologous chromosomes are separated but are first paired during the prophase stage to form the tetrad or bivalent structure.
Therefore, during prophase I, all four chromatids of the two homologues become closely associated as a result of pairing, forming a structure known as a tetrad or bivalent.

Answer:yes
Explanation:bcasue no iwoud nighcty was a time to be happy with you bruh was the night you had the best day I was just getting my dog and my dog food was really delicious the staff is very friendly and helpful the service and the food was delicious I would definitely come here for a drink union or any more than anything special about it haha was my first visit there for a long time
B. is correct. Let's look at the others...
A-- we know salt deposits are not alive.
C-- True, salt deposits are not alive, but they do not respond to stimuli... this is a characteristic of living things.
D-- Salt deposits are not alive and do not maintain homeostasis.
Velocity can vary as long there is specific direction (displacement)
Speed has no direction therefore change in speed is not necessary the velocity...
Velocity is also in a specified direction
The products of anaerobic respiration in yeast are carbon dioxide and ethanol.
<h3>Anaerobic respiration</h3>
This refers to respiration in the absence of oxygen.
In the absence of oxygen, both the citric acid cycle and the electron transport chain cannot proceed. Thus, only glycolysis takes place.
The two pyruvate molecules produced in anaerobic respiration in yeast are converted to ethanol, instead.
