S phase, or the Synthetic phase, is where the cell begins the synthesize genetic material.

Answer:
The correct answer will be the cell is in prophase I of meiosis and will enter metaphase I next.
Explanation:
Meiosis is a type of cell division which is involved in the formation of haploid gametes.
During meiosis the division of the genetic material is markedly observed and based on this meiosis is divided into 4 phases: prophase, metaphase, anaphase and telophase.
During prophase: the chromatin structure of DNA starts condensing to form chromatids which attaches to homologous chromatids and are known as sister chromatids. These sister chromatids exchange their genetic material via a process called called recombination or crossing over which takes place during pachytene stage of prophase I. After crossing over it is proceeded by the next stage that is metaphase I in which chromosomes gets aligned at the center of the cell.
Thus, the cell is in prophase I of meiosis and will enter metaphase I next is the correct answer.
Answer:
The correct answer is the neurotoxin known as tetanospasmin toxin.
Explanation:
Tetanus is a disease caused by a bacteria known as clostridium. The bacteria are found in soil, manure, dust, and saliva. It can enter the host body by a cut or rusted or dusty nail or burn. It causes muscle spasm or jaw locking or bone locking.
It releases the neurotoxin that is tetanospasmin toxin that inhibits the secretion of γ-aminobutyric acid (GABA) and results in a variety of symptoms associated with tetanus.
Thus, the correct answer is the neurotoxin known as tetanospasmin toxin.
The correct answer is:
CO2 diffuses passively out of the cell.
O2 in respiration is converted to water. O2 diffuses in to the cell.
Explanation:
Cellular respiration is the chemical reaction in which glucose and oxygen are converted into water, carbon dioxide, and energy (ATP). In this reaction, glucose and oxygen are reactants, while water, carbon dioxide, and energy (ATP) are products. Cellular respiration is a set of metabolic reactions and processes that take place in the cells of organisms to change biochemical energy from nutrients into adenosine triphosphate and then discharge waste products.
