LH and FSH by posterior pituitary while act on mature follicles to undergo ovulation. Estrogen and progesterone by ovaries and act on many things.
Answer:
D) Iron compounds are a catalyst for the decomposition of hydrogen peroxide.
Explanation:
The reaction of descomposition of hydrogen peroxide (H₂O₂) to produce oxygen (O₂) is:
2H₂O₂ → 2H₂O + O₂
Based on the data of potential catalys effects on reaction rate:
A) Iron compounds are always used as catalysts. <em>FALSE. </em>It is possible to know that, for this reaction, iron compounds are acting as catalyst but there is no information about all reactions to know that iron compounds are always catalysy
B) Reaction rate is always increased by iron compounds. <em>FALSE. </em>Again, for this reaction iron compounds increases reaction rate but it is not possible to know that reaction rate is always increased by iron compounds.
C) Increasing the temperature increases the rate of decomposition. <em>FALSE. </em>There is no information about temperature of reaction.
D) Iron compounds are a catalyst for the decomposition of hydrogen peroxide. <em>TRUE. </em>As both iron compounds increases the rate of reaction, it is possible to say that iron compounds are a catalyst for the descomposition of hydrogen peroxide.
I hope it helps!
Answer:
The correct answer is option (d) "both b and c".
Explanation:
Experimental model organisms used in scientific investigations have to fulfill certain criteria in order to be useful in the laboratory. Two of the desired characteristics are being able to reproduce quickly and with enough number of offspring in order to study genetic behaviors. <em>Arabidopsis thaliana</em> characteristics of being able to reproduce in 8–10 weeks and producing thousands of offspring per plant (because it can produce thousands of seeds) makes it a model flowering plant for experimental studies.
Answer:
What are the interactions in an ecosystem?
Species interactions within ecological webs include four main types of two-way interactions: mutualism, commensalism, competition, and predation (which includes herbivory and parasitism). Because of the many linkages among species within a food web, changes to one species can have far-reaching effects.
