Meiosis results in the formation of gametes.
B.
Meiosis produces recombinant chromosomes.
C.
Meiosis begins with a diploid cell, but produces four haploid cells.
Answer:
C. Meiosis begins with a diploid cell, but produces four haploid cells.
Explanation:
C. Meiosis begins with a diploid cell but produces four haploid cells.
The statement "Meiosis begins with a diploid cell, but produces four haploid cells" explains why meiosis is a reduction division. The cell divides twice during meiosis, resulting in the creation of four daughter cells. These daughter cells are genetically distinct from the parent cell and contain half the number of chromosomes (haploid) as the parent cell.
Most jellyfishes use a form of jet propulsion to move through seawater. ... This is what most jellyfish do. They squeeze their bodies in order to push jets of water from the bottom of their bodies to propel the jellyfish forward. Now check out another method of jellyfish propulsion, used by the comb jellyfish.
Hope this helps :D
b. anaphase
c. prophase
d. telophase
Sister chromatids line up at the equator of the cell during the metaphase stage of cell division. This arrangement is essential to ensure each new cell receives an exact copy of each chromosome. The next stage, anaphase, involves the separation of these chromatids.
The sister chromatids line up at the equator of the cell during the metaphase stage of cell division, whether it is mitosis or meiosis. The stage where sister chromatids align in the middle of the cell is integral to the process as it ensures that each new cell will receive one copy of each chromosome. In the next phase, anaphase, these chromatids are separated and drawn to opposite ends of the cell. Thus, the correct answer to your question is (a) metaphase.

The given statement, "Human movement involves the complex interplay of many body systems." is true. Human movement is a complex process that requires the coordination and interaction of multiple body systems. These body systems include the muscular system, skeletal system, nervous system, and cardiovascular system, among others.
The muscular system plays a vital role in movement by generating force and facilitating the contraction and relaxation of muscles. Muscles work in pairs, with one muscle contracting while the opposing muscle relaxes, allowing for controlled movement. This interplay of muscles is necessary for various movements, such as walking, running, and lifting objects.
The skeletal system provides structural support and serves as the framework for movement. It consists of bones, joints, and connective tissues. Bones act as levers, while joints allow for flexibility and facilitate different types of movement, such as bending, rotating, and extending.
The nervous system is responsible for controlling and coordinating movement. It receives and processes sensory information, sends signals to muscles to initiate movement, and regulates the speed and force of muscle contractions. The brain and spinal cord are integral components of the nervous system, playing a crucial role in coordinating complex movements.
The cardiovascular system, composed of the heart, blood vessels, and blood, transports oxygen and nutrients to the muscles involved in movement. It also carries away waste products, such as carbon dioxide, generated during muscular activity. Adequate blood flow and oxygen supply are essential for optimal movement and performance.
