A, as with all organisms, growth is always the primary result of cell division, the mitosis type, meiosis cell division results in gametes (sperm and eggs)
<span>The correct answer is: It is used to synthesize ATP through substrate-level phosphorylation.</span>
<span>The free energy released as electrons are passed from photosystem II to photosystem I drive pumping of H+ and building a gradient. H+ flow down their gradient and when they pass through ATP synthase, the ATP is produced by substrate-level phosphorylation (ADP+Pi).</span>
The organism can produce 12 genetically different gametes.
<h3><u>Explanation:</u></h3>
The gametes are the unit of sexual reproduction which are produced by an organism from their germ mother cell by means of meiosis. This gametes do carry half the amount of total chromosomes that is present inside each cell of that organism. This process let's the genetic combinations of chromosomes to get more variations among offsprings. But this isn't the only source of variation among the offsprings.
Each and every germ mother cell that's undergoing the meiotic division undergoes a process called crossing over and chaismata formation which gives the genetic mixing among the different alleles of same character among the organism.
Thus, statistically, if the organism has n pairs of chromosomes, then the organism will be able to produce 2n number of genetically different gametes which helps in finding out the probability of genotype of the offsprings.
So if the organism has 6 pairs of chromosomes, then the organism will be able to produce 12 genetically different gametes.
Answer: muscle contraction of sustained force resulting from repeated action potentials. (Option A)
Explanation: Tetanus is also called physiologic tetanus. Tetanus refers to the contraction of the muscle, which is established when the motor nerve that supply nerves to a skeletal muscle produces action potentials at a very high degree.
However, tetanic contraction is usually a normal process (such as when carrying a heavy box). Also, muscles can be shorten, lengthen or remain constant length during tetanic contractions.
The first step in the formation of the human embrayo and it is called fertilization.
<h3>What is fertilization?</h3>
The first step in the formation of a human embrayo is called fertilization. The term fertilization has to do with fusion of the male and female gametes to form a zygote.
Hence, the diagram as shown is the first step in the formation of the human embrayo and it is called fertilization.
