5 0

<u>Option a,d and </u>e are the the components of cell theory as outlined by schleiden, Schwann, and virchow.

Cell theory is a scientific principle first formulated in the mid-19th century, that living organisms are made up of cells, that they're the basic structural/organizational unit of all organisms, and that each cell come from pre-present cells.

The TheCell theory states that all biological organisms are composed of cells; cells are the unit of lifestyles and all lifestyles come from preexisting life. The cellular principle is so set up nowadays that it paperwork one of the unifying concepts of biology.

The Cell theory is vital because it explains the concept of the cell and includes the subsequent postulates: The cellular is the fundamental unit of existence. All cells get up from pre-existing cells i.e Omnis cellula e cellula. All living organisms on the earth are made of cells.

Flow Chart What happens to food and energy when it enters the cell? Finish the description for each organelle. Step 1: Mitochond

torisob [31]

Explanation:

Eukaryotic cells have specialized mechanisms to transport molecules along with membrane-bound organelles like the endoplasmic reticulum that provide a higher surface area for absorption and enable more efficient transportation.

Their structural components (i.e. their makeup) determine their function (what they do). In specific cell types, collected proteins may function as a unit called an organelle. Some organelles are bound by membranes like those that make up the external structure of the cell, with varying compositions of phospholipids and proteins. Several organelles facilitate the digestion of nutrients into metabolites and energy...

Step 1: Mitochondria break down food and release energy; In all eukaryotic cells mitochondria are small cellular organelles bound by membranes. The higher concentrations of reactants and solutes, increases metabolic reaction efficiency; these make most of the chemical energy required for powering the biochemical reactions within the cell. This chemical energy is obtained via the breakdown of nutrients from food, and is stored within the molecule ATP. Respiration in the mitochondria utilizes oxygen for the production of ATP in the Krebs’ or Citric acid cycle via the oxidization of pyruvate (through the process of glycolysis in the cytoplasm) where several metabolites used for building other compounds are produced.

Step 2: Lysosomes... Some organelles separate proteins and molecules that may harm the cell by parceling them into membrane-bound organelles for example, proteases bound within lysosomes can break down many structural proteins, and carbohydrates found in food, waste, and cell components

Step 3: Vacuoles... Vacuoles are fluid filled organelles which store concentrated amounts of solutes, and waste products. Specialized vacuoles are also used to transport components to the cell membrane for cellular export.

Step 4: The endoplasmic reticulum... Most proteins that function in the cytosol (such as actin) or in the nucleus (such as DNA polymerase) are synthesized by free ribosomes. Proteins that function within the endomembrane system (such as lysosomal enzymes) or those that are destined for secretion from the cell (such as insulin) are synthesized by bound ribosomes in the rough endoplasmic reticulum. The rest of the ER, which does not contain ribosomes is called the smooth ER, and may contain lipids, enzymes, and other proteins. As a protein destined for the endomembrane system is being synthesized by a ribosome, the first amino acids in the growing polypeptide chain act as a signal sequence. That signal sequence ensures that the ribosome binds to the outer membrane of the ER and that the protein enters the ER lumen.
Step 5: Golgi bodies... Like a post office, the golgi complex, or golgi body recognizes signal sequences and packages these compounds into lysosomes for delivery to their final destination. Lysosomes fuse with the plasma membrane to empty their contents into the extracellular space.

Part 1: Why is Fresh Water in Short Supply?

shepuryov [24]

Part 1;

Because there is only limited amounts of fresh water on the Earth the rest is salt water; which humans can not survive on as the salt dehydrates our bodies instead of hydrates.

1) The more we try to get the the fresh water the more we will likely make more pollution.

2) The more we use the less there is.

3) Everything needs water.

Part 2; no idea I believe it is the ice caps, as it is fresh water in the ice caps and not a lot of humans up there to pollute the runoff.
