Answer:A phase change is a physical process in which a substance goes from one phase to another. Usually the change occurs when adding or removing heat at a particular temperature, known as the melting point or the boiling point of the substance. Removing heat from a substance changes a gas to a liquid or a liquid to a solid.

Answer:

eukaryotic cells

Explanation:

All cells fall into one of these two broad categories. Only the single-celled organisms of the domains Bacteria and Archaea are classified as prokaryotes—pro means before and kary means nucleus. Animals, plants, fungi, and protists are all eukaryotes—eu means true—and are made up of eukaryotic cells.

Answer:

simple columnar epithelial tissue or Stratified squamous nonkeratinized epithelium

Explanation:

Most mucous membranes contain stratified squamous or simple columnar epithelial tissue. The epithelial tissue sheet lies directly over the layer of loose connective tissue called lamina propria.

The special cell division process of meiosis is undergone by gametes, which are reproductive cells responsible for sexual reproduction. Thus, correct answer is option (1).

Meiosis is a special type of cell division that only takes place in organisms that reproduce sexually. , which are sex cells like eggs and sperm, are produced as Gametesa result of two sequential divisions. Gametes have half as many chromosomes as parent cells, ensuring that the offspring they create during fertilization will have the right number of chromosomes.

Gametes are created by meiosis to retain genetic variation in the population, as opposed to somatic cells, which go through mitosis to produce identical duplicates. Hepatocytes, lymphocytes, and neurons all go through mitosis or perform certain bodily roles; none of these cells go through meiosis.

CLAIM: IF THE FUSED B CANCER CELLS ARE GROWN IN A MEDIUM THAT DOES NOT CONTAIN NITROGEN SOURCE, THE CELLS WILL STOP SYNTHESIZING PROTEINS AND THEIR LIFE SPAN WILL BE GREATLY REDUCED

Explanation:

The growth medium that was used to reproduce the fused cancer B cells contains nitrogenous compounds that serves as source of nitrogen for the production of nitrogenous bases of DNA, If the nitrogen source is removed, the DNA in the nucleus of the white blood cell will lack adenine and guanine, which are necessary for the synthesis of DNA molecules.

2. Nitrogen is an integral part of DNA and protein. Nitrogen is needed to produce nitrogenous bases that are found in DNA. The DNA molecule is the one that initiate and direct the synthesis of protein in living cells.

In the fused B cancer cells, DNA must be produced, so that the dividing cancerous cells can continue their uncontrolled division, this will keep the cells alive. Nitrogen is also needed for the continuous synthesis of the special protein that the fused B cell is producing.

Thus, if nitrogen source is removed from the growth medium used for the cultivation of fused B cells, then the cells will stop synthesizing protein, their life span will be greatly reduced and they will eventually die out.

Answer:

Water moving across the earth in streams and rivers pushes along soil and breaks down pieces of rock in a process called erosion. The moving water carries away rock and soil from some areas and deposits them in other areas, creating new landforms or changing the course of a stream or river.

Answer:

The digestive system is made up of the alimentary canal (also called the digestive tract) and other organs, such as the liver and pancreas. The alimentary canal is the long tube of organs — including the esophagus, stomach, and intestines — that runs from the mouth to the anus.

In mammals, the digestive tract is made up of multiple organs such as the stomach, pancreas, and intestines. These all work together to form the alimentary canal we use to digest food.

The digestive system in mammals is a complex network of organs and structures responsible for breaking down food into nutrients that can be absorbed and utilized by the body. The digestive tract, also known as the alimentary canal or gastrointestinal tract, consists of several organs that collaborate to facilitate the digestion and absorption process.

Stomach: The stomach is a muscular organ that receives and churns food, mixing it with gastric juices containing enzymes and acids to begin the process of digestion. It plays a crucial role in breaking down proteins.

Pancreas: The pancreas is both an endocrine and exocrine gland. Its exocrine functions involve producing digestive enzymes that are released into the small intestine to further break down carbohydrates, proteins, and fats.

Mouth: The mouth is where food is chewed and mixed with saliva. Saliva contains enzymes that start to break down carbohydrates.

Esophagus: The esophagus is a muscular tube that carries food from the mouth to the stomach.

Small intestine: The small intestine is the longest part of the digestive tract. It is where most of the nutrients from food are absorbed.

Large intestine: The large intestine is shorter than the small intestine. It absorbs water and salts from food and stores waste products until they are eliminated from the body.

Rectum: The rectum is the last part of the digestive tract. It stores waste products until they are eliminated from the body.

The digestive tract is a vital organ system that is essential for the survival of mammals. It allows mammals to obtain the nutrients they need from food to stay alive and healthy.

The stomach and the cells that comprise it have a three-part protection system to protect from the acid contained in the stomach, comprised mostly of compact cell unions.

The stomach is one of the main digestive tract organs. Its job is to break down the food we ingest and pass it along to the rest of the digestive tract. To perform this action, the stomach secrets hydrochloric acid. However, the stomach itself is not damaged by this acid due to a three-part protective system comprised of:

The cells present in the epithelial lining of the stomach join one another via compact cell unions to form a closed barrier which is then covered by a thick Mucose barrier. This along with the secretion of bicarbonate which works to break up the acids present in the stomach and ingested, form a sealed barrier that protects the stomach from harm.

Answer:

Metaphase is the second stage of cell division, between prophase and anaphase, during which the chromosomes become attached to spindle fibers.  A metaphase separates duplicated genetic material that is carried in the nucleus of a parent cell and then converts it into two identical daughter cells.

Answer:

Metaphase is a stage in the cell cycle where all the genetic material is condensing into chromosomes. These chromosomes then become visible. During this stage, the nucleus disappears and the chromosomes appear in the cytoplasm of the cell. As metaphase continues, the cells partition into the two daughter cells.
