What is carbon flux? a. movement of carbon from one reservoir to another b. stagnancy of carbon in one reservoir c. lack of carbon in any particular reservoir d. consumption of carbon

Option A, movement of carbon from one reservoir to another

Explanation:

Carbon flux is defined as the exchange of carbon between different sources of carbon termed as carbon pool or reservoir. The carbon is exchanged between different carbon pools through the process of combustion, liquefaction, respiration, phosynthesise, dissolution, decomposition etc. The carbon flux at global level is measured in gigatonnes and is also sometimes referred to as carbon cycle where carbon is exchanged between different environment components in different forms

fertilization, pictured in figure 24.23a is the process in which gametes (an egg and sperm) fuse to form a zygote. the egg and sperm each contain one set of chromosomes. to ensure that the offspring has only one complete diploid set of chromosomes, only one sperm must fuse with one egg. in mammals, the egg is protected by a layer of extracellular matrix consisting mainly of glycoproteins called the zona pellucida. when a sperm binds to the zona pellucida, a series of biochemical events, called the acrosomal reactions, take place. in placental mammals, the acrosome contains digestive enzymes that initiate the degradation of the glycoprotein matrix protecting the egg and allowing the sperm plasma membrane to fuse with the egg plasma membrane, as illustrated in figure 24.23b. the fusion of these two membranes creates an opening through which the sperm nucleus is transferred into the ovum. the nuclear membranes of the egg and sperm break down and the two haploid genomes condense to form a diploid genome.

explanation:

meiosis is the first to occur after the nuclei of opposite of opposite mating types fuse
