I think the correct answer from the choices listed above is option D. Destruction of tundra vegetation will likely result in melting of the permafrost. The tundra ecosystem is extremely sensitive to disturbance with little ability to restore itself. The melting of the permafrost will <span>cause the collapse of ground and loss of soil. </span>

1. Enzyme is the molecule that serves to make reactions work. Enzymes are biochemical catalysts that catalyses chemical reactions in a cell by acting on substrates and convert them to products. Their rate of action increases with increase in substrate concentration, reaching optimum when all active sites of the enzyme are engaged.

2. Plastid are the tiny sacs in the cell that may contain starch. Plastid are major cell organelles found in the cells of plants and algae. Plastids are site for the manufacture and storage of important  chemical compounds used by the cell. They often contain pigments used in photosynthesis, and the types of pigments present can change or determine cells color.

3. Lysosome are packets within the cell that contain digestive enzymes. Lysosomes are one of many organelles found in animal cells. they are tiny like sacs filled with enzymes that enables the cell to process nutrients. They contain digestive enzymes which helps in the digestion of worn out organelles, food particles and engulfed viruses or bacteria.

4. Mitochondrion is a structure within a cell that is responsible for production of energy. Energy in a cell is produced through a process of cellular respiration which involves use of nutrients with oxygen gas to yield energy inform of ATP, water and carbon dioxide. The process takes place in the mitochondrion where oxygen acts as proton acceptor in the electron transport chain coupled by production of energy.

5. An Organelle is a small structure that serves specialized functions. A cell is made up of various organelles that help it perform its functions. Each organelle is specialized to perform as specific function different from other organelles, for example ribosomes is an organelle involved in the manufacture of proteins.

6. Golgi apparatus are group of flattened sacs that package and export materials out of the cell. Golgi apparatus also called golgi complex or golgi body, is a membrane bound organelle in eukaryotic cells that is made up by a series of flattened, stacked pouches called cisternae. They are responsible for transporting, modifying, and packaging proteins and lipids into vesicles.

7. Vesicles are tiny sacs connected to the Endoplasmic reticulum and Golgi apparatus. Vesicles are small structures within a cell, or extracellular, consisting of fluid enclosed by a lipid bi-layer. they form naturally during the process of secretion (exocytosis), uptake (endocytosis) and transport of materials within the cytoplasm.

How the DNA is different from the cDNA?
Alexandra [31]

Answer:

gDNA = "genomic DNA" and cDNA = "complementary DNA." cDNA is classically associated with being reverse transcribed either from all extracted RNA from a tissue or cell (total RNA) including (in eukaryotes) pre-mRNA, ribosomal RNA, tRNA, snoRNA, miRNA and mRNA, etc.) while cDNA obtained only from reverse transcription of the mRNA (expressed eukaryotic cytosolic mRNA) fraction (e.g., by poly[dT]n and random priming) is complementary DNA (cDNA) made from what is called the "transcriptome." Eukaryotes have introns and exons in the gDNA, while prokaryotes do not. So eukaryotic cDNA reverse transcribed from mRNA lacks introns. Prokaryotic-derived cDNA is always complementary to prokaryotic RNA and gDNA (so is always necessary to have a good DNase treatment prior to gene expression analysis by e.g., qPCR for prokaryotic transcriptome work)...

Use the model to explain how celiac disease interrupts the normal transportation of energy and other nutrients from the digestiv
IrinaK [193]

Answer:

According to the model, the "villi" of small intestines is being damaged as an impact of celiac disease. Small intestines are responsible for absorption of nutrients and minerals from food, this occurs through villi, in case of damaged villi absorption is interfered, thus disturbing the digestive system. If the nutrients, minerals or vitamins are not being absorbed well by small intestines then they will be excreted out of the body and will not be transported to the blood and other areas, this would result in deficiency of minerals and vitamins  in blood that cause weakness.
