Explanation:
Drag each tile to the correct location on the image.
Place the labels to describe the role of the lungs and blood in transporting oxygen and carbon dioxide in the body.
Blood cells transport
carbon dioxide to
the lungs.
Oxygen from the
lungs enters the
alveoli in the lungs.
Red blood cells supply
oxygen to the cells of
different organs in
the body.
Oxygen enters
the red blood cells
in the capillaries.
Red blood cells
collect the waste
carbon dioxide.
Answer:
Once the oxygen diffuses across the alveoli, it enters the bloodstream and is transported to the tissues where it is unloaded, and carbon dioxide diffuses out of the blood and into the alveoli to be expelled from the body. Although gas exchange is a continuous process, the oxygen and carbon dioxide are transported by different mechanisms.
Transport of Oxygen in the Blood
Although oxygen dissolves in blood, only a small amount of oxygen is transported this way. Only 1.5 percent of oxygen in the blood is dissolved directly into the blood itself. Most oxygen—98.5 percent—is bound to a protein called hemoglobin and carried to the tissues.
Hemoglobin
Hemoglobin, or Hb, is a protein molecule found in red blood cells (erythrocytes) made of four subunits: two alpha subunits and two beta subunits (Figure 20.19). Each subunit surrounds a central heme group that contains iron and binds one oxygen molecule, allowing each hemoglobin molecule to bind four oxygen molecules. Molecules with more oxygen bound to the heme groups are brighter red. As a result, oxygenated arterial blood where the Hb is carrying four oxygen molecules is bright red, while venous blood that is deoxygenated is darker red.

Can diffuse? YES or NO
Molecule
Glucose
Starch
Protein
Iodine
Water
Salt
Answer: Molecule: Some molecules, such as carbon dioxide and oxygen, can diffuse across the plasma membrane directly, but others need help to cross its hydrophobic core. In facilitated diffusion, molecules diffuse across the plasma membrane with assistance from membrane proteins, such as channels and carriers.
Glucose:Glucose cannot move across a cell membrane via simple diffusion because it is simple large and is directly rejected by the hydrophobic tails. Instead it passes across via facilitated diffusion which involves molecules moving through the membrane by passing through channel proteins.
Starch: Starch does not pass through the synthetic selectively permeable membrane because starch molecules are too large to fit through the pores of the dialysis tubing. ... Diffusion results from the random motion of molecules. Diffusion moves substances from regions of higher concentration to regions of lower concentration.
Protein: Can all membrane proteins diffuse freely around the membrane? Many, but not all membrane proteins can diffuse laterally through the lipid bilayer. Some proteins cannot do this because of their attachment, either to other proteins or to the underlying cytoskeletal filaments.
Iodine: The Dialysis tubing provides a semi-permeable membrane. Only allowing smaller molecules to pass through it. Iodine molecules are small enough to pass freely through the membrane, however starch molecules are complex and too large to pass through the membrane. ... Thus iodine diffused into the tube with the starch.
Water: Water also diffuses away from areas of high free water concentration into areas of more solute concentration. ... Thus, only water can diffuse. This diffusion of water across a semi-permeable membrane is called osmosis.
Salt: In turns out when salts are exposed to water, they dissolve into charge atoms (called ions). These atoms are very tiny and mobile and can easily diffuse from the surface past the meat molecules, given enough time.

In which of these processes does cell specialization occur?
Which of these statements is NOT a cause of the controversy? a. Henrietta died of cervical cancer b. Henrietta was not told about the cells c. Private genetic Information was made public d. Cells were sold for hundreds of dollars yet the family is extremely poor
Answer:
The correct answer is A. It is not a cause of the controversy the fact that Henrietta died of cervical cancer.
Explanation:
The fact that Henrietta has died as a result of the development of cervical cancer is not in itself controversial, since cancer as such is a random situation that cannot be predicted or avoided by doctors, but only treated medically. once developed.
However, the fact that the treatment has been sold for a very high amount in the case of a poor family (since economic interests were prioritized over the right to health), the fact that Henrietta has not been informed regarding the cells (violating their right to information and the protection of their health), and the fact that private genetic information has been publicly disclosed (since in that case, the right to privacy would also be violated).

A. independent variable
B. extraneous variable
C. control group
D. controlled variable
E. dependent variable
Answer: Control Group
Explanation:
A group in which everything is the same as the test group except that the independent variable stays the same is a control group that is in option C, as the control groups never change.
What is the significance of the control group in the experiment?A control group is a set up in a scientific experiment that serves as a baseline for comparison with other unknown samples, and after testing the control group with the results of the treatment group, researchers can determine the effect of the independent variable. The control group is the sample whose value is known to the scientists.
Hence, a group in which everything is the same as the test group except that the independent variable stays the same is a control group that is in option C, as the control groups never change.

Explanation:
A student was setting up beakers that contained different solutions in order to conduct a laboratory investigation, but the next day he could not tell which beaker contained the starch and water mixture. In order to find out which beaker contained starch, he took small sample from each of the beaker and conducted a test for starch on each of them. Describe the test for starch that the student should use and the result that would indicate the presence of starch
Answer:
See the answer below
Explanation:
In order to test for starch and distinguish the beaker containing a mixture of startch and water, a small quantity of the solutions in each beaker should be taken and and drops of iodine added. The solution that gives off a blue/black color from the yellow/brown color of the iodine would be the starch water solution.
Generally, starch turns iodine solution to blue/black from the usual yellow/brown color of the substance.

All eukaryotic cells are multicelular?
True
False
Answer:
Uhhhh false, multicellular means a living thing made up of two or more cells soooooooooo...
Explanation:
Multicellular creatures use a variety of cells to perform their many duties, in contrast to unicellular organisms, which consist of just one cell that performs all the processes required by the organism.
What is unicellular and multicellular in eukaryotes?In a unicellular creature, a single cell manages the life process. A multicellular organism's numerous cells are each specialized to perform certain functions.
Eukaryotes and prokaryotes are both examples of unicellular creatures. However, only eukaryotes are classified as multicellular organisms. Because of this, these cells are often larger than prokaryote cells.
Eukaryotes do contain cell nuclei, and they have more intricate structures. A few examples of unicellular eukaryotes are yeast and algae. Eukaryotic cells, in contrast to prokaryotes, have organelles, which serve crucial roles inside the cell.
Therefore, it is false that all eukaryotic cells are multicellular.

Answer:
Amino Acids im pretty sure
Nitrogen is an essential element required by all the organisms present on the Earth. Nitrogen is found in all amino acids and nucleotides. The nitrogen from animal waste can be stored as nitrate, ammonia, or nitrites.
Nitrogen is an essential compound, which makes up the amino acid and many other biomolecules.
The nitrogen is released into the atmosphere through animal manures or waste. Animal manure serves as the source of nitrogen for plants and other organisms.
The nitrogen released by the aquatic organisms is the primary source of circulation of nitrogen in the marine environment.
The nitrogen when dissolved in the water exists as nitrates, ammonia, or nitrites.
Therefore, nitrogen exists as nitrates and nitrites when stored in water bodies.

How do waterfalls form? A meander gets cut off. Sediment builds up. Soft rock erodes. Flat areas flood.
Answer:
The correct answer is "soft rock erodes."
Explanation:
Waterfalls form as streams flow from soft rock to hard rock. This happens as a stream flows across the earth and as the stream drops in a waterfall. In both cases, the soft rock erodes, leaving a hard ledge over which the stream falls.
As streams go from soft rock to hard rock, waterfalls are created. This occurs as a stream travels across the surface of the ground and as it descends in a cascade.
What is waterfall?The first Process Model to be introduced was the Waterfall Model. The term "linear-sequential life cycle model" is also used to describe it. There is no overlap between phases in a waterfall model; each step must be finished before the subsequent phase can start.
The first SDLC methodology for software development was the waterfall model.
The software development process is depicted using the waterfall model, which follows a linear sequential flow. This implies that a phase of development can only start if the one before it is finished.
Therefore, As streams go from soft rock to hard rock, waterfalls are created. This occurs as a stream travels across the surface of the ground and as it descends in a cascade.
