Answer:
True
Explanation:
Prokaryotic cell or bacterial cell contain cell wall which is made up of peptidoglycan and traditional antibacterial antibiotics were able to interfere with the cell wall synthesis and cause the destruction of bacterial cells.
For example, one of the most traditional antibiotic is penicillin which inhibit the synthesis of bacterial cell wall by blocking transpeptidation reaction. As it inhibits new cell wall formation it results in the formation of holes in the cell wall.
These holes in the cell allow movement molecules inside the cell and cause osmotic cell lysis. Therefore the statement is true.
The right answer is metaphase II.
The process is performed in two nuclear and cytoplasmic divisions, called first and second meiotic division or simply meiosis I and meiosis II. Both include prophase, metaphase, anaphase, and telophase. First division prophase is long and consists of 5 stages: leptotene, zygotene, pachytene, diplotene, and diakinesis. It is at this point that genetic recombination takes place at the level of chiasmus.
During meiosis I, the members of each homologous pair of chromosomes are paired during prophase, forming bivalents. During this phase, a protein structure, called synaptonemal complex form, allows recombination between homologous chromosomes. Subsequently, a large condensation of the bivalent chromosomes occurs and go to the metaphase plate during the first metaphase, resulting in the migration of n chromosomes to each of the poles during the first anaphase. This reduction division is responsible for maintaining the number of chromosomes characteristic of each species.
In meiosis II, as in mitosis, the sister chromatids comprising each chromosome are separated and distributed between the nuclei of the daughter cells. Between these two successive steps, there is no DNA replication. The maturation of the daughter cells will result in the gametes.
Answer:
B. Oxygen
Explanation:
Oxygen is a substance transported with the assistance of red blood cells
Answer:
Predator-Prey Relationship
Explanation:
If the extinction of one of the species leads to an increase in the population of the other species, then the relationship must be a predator-prey relationship, because the now-extinct species was keeping the now-increasing population of the other species in check.
