I believe the best answer would be B. Moderate rainfall and no extreme temperatures. I hope this helps. :)
Answer:
The correct answer will be option-C
Explanation:
The rhythm of the heartbeat is controlled by the pacemaker of the heart called the sino-atrial node.
The SA node generates action potentials which trigger the contraction and relaxation of the atrium and ventricles. The membrane potential generation initiates by the depolarization of the cell membrane when the L type of Ca⁺² ions opens up and calcium ions enter the cell.
This depolarizes the cell until the potential threshold is reached which lies between the -40 and -30 mV.
Thus, Option-C is the correct answer.

Answer:
Explanation:
In the members of the class ascomycetes such as yeast, two haploid yeast cells of two different stains or mating types fuse to form a diploid zygote. Zygote quickly undergoes meiosis or reductional division to form four haploid spores called a tetrad. The tetrad is contained in a sac-like structure called an ascus or fruiting body. Formation of ascus is the characteristic feature of ascomycetes. In the ascus tetrad are not arranged in any specific order. The tetrad are called random or unordered spores. The genetic analysis of the genotypes in the tetrad can tell us about the events during meiosis.
