Answer:
1. Meiosis I
2. Tetrad
3. Tetrad
Explanation:
Crossing over refers to an event taking place in the cells undergoing meiosis cell division during which the exchange of material takes place. The process of crossing over takes place during pachytene of prophase I in meiosis I.
Crossing over takes place when the structure formed by the pairing of the four chromatids of the chromosomes called tetrad is formed. The formation of tetrad allows the exchange of genetic sequences, therefore, result in recombination.
The process of crossing over does not take place in the mitosis as the tetrad is not formed in the mitosis.
Thus, Meiosis I, Tetrad and tetrad are correct.
Answer:
Explained below.
Explanation:
Conduction happens when two substances at various temperatures are in connection with various other. Heat flows from the hotter to the colder substance continuously till both are at the similar temperature. Conduction signifies the transfer of heat throughout a substance by the collision of particles. The above explanation makes easy for us to understand the given statement "heat flows from substances."
Answer:
D
Explanation:
A hypotonic solution means it is less concentrated in relations to the other solution – in this case the patient’s cells. The electrolytes that balance osmotic pressure in the body are sodium, potassium, chlorides, calcium, and etcetera. The IV needs to have less electrolytes so that when the IV is injected into the patient’s blood the water can move into the cells by osmosis. Osmosis continues until the cell cytoplasm is in osmotic equilibrium with the blood. It is imporant, therefore, to have the right electrolyte balance in the IV solution otherwise the cell will over-hydrate and begin lysing – especially if the kidneys of the patient do not rid excess water fast enough.

Calcula el voltaje existente entre los extremos de una resistencia de 100 Ω por la que circula 0,1 A
V=A×R
V=0.1 A×100Ω
V=10 Voltios
bueno eso me sale XD ojala te ayude :D
