Sister chromatids of a chromosome are joined at a region called the centrosome. TrueFalse
The statement is false. Sister chromatids of a chromosome are joined together at a region called the centromere, not the centrosome. The centrosome, on the other hand, is an organelle found in animal cells that is responsible for organizing microtubules during cell division.
During the S phase of the cell cycle, DNA replication occurs, resulting in the formation of two identical sister chromatids, which are held together at the centromere. The centromere contains a specialized region of DNA called the kinetochore, which serves as an attachment site for microtubules of the spindle apparatus during cell division. The centrosome plays a critical role in the organization and assembly of the spindle apparatus during cell division. The centrosome contains two centrioles, which serve as the organizing centers for the microtubules that make up the spindle apparatus. The spindle apparatus is responsible for separating the sister chromatids during cell division, ensuring that each daughter cell receives a complete set of chromosomes.

What happens when an organism suffers or dies form lack of food? (Vocabulary)
When an organism suffers or dies from lack of food, it undergoes starvation.
When an organism suffers or dies from a lack of food, it experiences malnutrition, which can lead to weakened immune systems, impaired growth and development, and eventually, starvation. In extreme cases, this can result in the organism's death due to the inability to maintain vital bodily functions.
Starvation can lead to a number of physiological changes such as a decrease in body weight, loss of muscle mass, and a weakened immune system. As the body tries to conserve energy, the metabolism slows down and the body begins to break down stored fat and muscle tissue to provide energy. If the lack of food continues, the body will eventually be unable to sustain itself and the organism will die from starvation.

Prophase, Metaphase, Anaphase, Telophase, and cytokinesis (PMAT). Interphase happens
BEFORE meiosis begins (cell prepares for division by duplicating DNA). Make a sketch of
each step and include a brief description on what is happening in that step.
Meiosis is a specialized type of cell division that occurs in sexually reproducing organisms. It results in the formation of haploid gametes, which contain half the number of chromosomes found in a diploid cell. Meiosis is divided into two stages: meiosis I and meiosis II.
Meiosis I is the first stage of meiosis and is characterized by the pairing of homologous chromosomes, which results in the formation of tetrads. During prophase I, homologous chromosomes exchange genetic material through a process called crossing over. This genetic exchange between homologous chromosomes results in the generation of new combinations of alleles, thereby increasing genetic diversity. Meiosis II is the second stage of meiosis and involves the separation of sister chromatids, which results in the formation of four haploid daughter cells.
