Answer:
The correct answer will be option-many antibiotics cannot penetrate the blood-brain barrier
Explanation:
Meninges is the membrane which surrounds the spinal cord and the brain and the infection of the meninges is thus called meningitis and Encephalitis is the inflammation of the brain. These two diseases are caused by the micro-organism which could be viruses, bacteria or fungus.
The treatment of the disease is difficult sometimes as the entry of the drug into the brain through the cellular membrane of the capillaries is inhibited like in the case of penicillin which is polar and finds difficult to cross the membrane.
Thus, the selected option is the correct answer.
Short term goals are usually easy and will take a short amount of time to achieve. Longer term goals take a while and are harder or take a while to achieve.
Each haploid sperm cell will have only 23 chromosomes.
<span>Meiosis is the process of cell division by which involving gametes. Cell division is just the same for sperm and egg cells, but they have distinguishable descriptions and labels in the process. Spermatogenesis is for the males’ sperm cells and oogenesis is the process for females’ egg cells. The cell division of meiosis involves the two phases, respectively meiosis I and meiosis II. </span>Meiosis I like mitosis is the cell division that produces diploid cells<span>. These diploid cells are cells that contain a complete pair of chromosomes which is 46. The result is two diploid cells after the first meiosis. To provide clear explanation, in contrast haploid cells only contain 23 chromosomes and are created after meiosis II which is 4 in number.<span> </span></span>
