The correct answer is B. Tan was proud of her mother who had a unique way of communicating in English language that is why in her book she chooses to discuss about her mother.
Tan and her mother they had a close relationship because,
1. Tan's mother used to attend tans lectures.
2. Her mother trusts and relies on her to talk to doctors about the scan of CAT.
Tan is the author of this essay which is entitled as the" mother tongue". The message of Tan's essay is that communication is more about intent and not specific word and words usage.
Answer: D) The amount of air in a room never changes.
Explanation: Equilibrium is defined as the state in which the concentration of reactants and products is constant or the rate of forward direction is equal to the rate of backward direction.
a) The percentage of nitrogen gas in a room decreases steadily: the amount decreases that means the reaction is taking place in one direction and hence the reaction is not in equilibrium.
b) A blade of grass grows taller : the plant gets taller that means the reaction is taking place in one direction and hence the reaction is not in equilibrium.
c) The amount of water in a cup decreases as it evaporates: The amount of water is decreasing that means the reaction is taking place in one direction and hence the reaction is not in equilibrium.
d) The amount of air in a room never changes: the amount of air does not change as the amount of air leaving the room is same as that of the air entering the room and hence the reaction is in equilibrium.
Answer:
The correct answer is D. The cytochromes
Explanation:
Cytochromes are proteins which contain tightly bound heme metal which easily undergoes oxidation and reduction and are responsible for accepting and donating the electron. They play an important role in the electron transport chain and helps in formation of ATP during oxidative phosphorylation.
The metal ion provides the capability to the cytochrome to gain and loss the electron. a, b, and c are the three classes of cytochrome out of which cytochrome c is the most abundant and stable.
Therefore the redox carrier of ETC that have bounded metal atom are cytochromes.
Answer:
Experiment 4. Relaxed, the drug will stop the calcium so that it does not act on the troponin
Experiment 5. Contraction: In order for the muscle to relax, the actin and tropomyosin union must occur.
Experiment 6. Relaxation: the release of the actin-myosin complex occurs with consumption of ATP, thus it slides and generates contraction, by adding a hydrolyzable analog, this reaction is avoided giving rise to a prolonged actin-myosin binding which leads to relaxation while last effect.
Experiment 7. Ca2 + Contraction is very necessary so that during muscle contraction troponin can be extracted.
Scientists have isolated the gene that produces the bioluminescence protein and inserted the gene into the embryos of tetra fish. This results in tetra fish that produce a green glow.
<h3>How, support your answer?</h3>
Tetra fish is a type or an example Glofish that has undergone genetic modifications whereby the gene in jelly fish that produces the green fluorescent protein (GFP) was extracted and inserted into the embryos of the tetra fish thereby causing them to glow or fluoresce in the presence of Ultraviolet light or natural light.
The genetically modified tetra fish passes this fluorescent gene from one generation to another.
Thus, The aim of this genetic modification in tetra fish was to be able to detect water pollution in the sea using the glow of the tetra fish.
