The excretory system is responsible for removing all of the following from the body excep t

A. Toxic Waste B. Gaseous Waste C. Dissolved molecules D. Cells

Answer:

D. Cells

Explanation:

The excretory system consists of organs that help the body to get rid of excess and waste materials from the body, and also helps in maintaining internal homeostasis in the body. These organs include the large intestine, skin, lungs, kidneys. Most of the wastes are products of metabolism. These waste materials that are no longer useful to the body could be in liquid or gaseous form. Examples of substances removed from the body by the excretory system are urine, feces, sweat etc.

Cells are not part of the substances removed by the excretory system.

Which of these processes is responsible for generating the most ATP within cellular respiration?A. The electron transport chain
B. Glycolysis
C. The breakdown of glucose into pyruvic acid
D. Krebs cycle

Answers

Glycolysis is the process responsible for generatingthe most ATP within cellular respiration

During cellular respiration, thefood molecules such as glucose, are oxidized to carbon dioxide (CO2) and water (H2O)and trapped in ATP (Adenosine triphosphate) form for further us of cell’sactivities. ATP’s are formed at mitochondria – the cell’s powerhouse. This typeof organelle takes and breaks nutrients absorbed by the cell and creates energyafterward. The energy from ATP is then used by the body in kinetic activitieslike running & walking or involuntary activities like breathing, bloodcirculation, stimulus-responding, etc.

Crossing over and the separation of duplicated homologous chromosomes in the first division produce genetic variation. true false User: The nuclear envelope disintegrates during _____.
metaphase
prophase
anaphase
telophase

Answers

Question 1. The statement that 'Crossing over and the separation of duplicated homologous chromosomes in the first division produce genetic variation' is true. Crossing over is the exchange of genetic material between homologous chromosomes that occurs during meiosis. As the result, the daughter cells are genetically different from mother cells. It is one of the ways to produce genetic variation. Question 2. The nuclear envelope disintegrates during prophase. This is the process that occurs at the beginning of mitosis. During prophase, the first phase of mitosis, the chromosomes condense and the nuclear envelope disintegrates. At the end of mitosis, the chromosomes will decondense and the nuclear envelope will re-form.

Prophase is the answer
