Red pigment found in vertebrate blood that functions in oxygen transport is

Biology
1 answer:
Margarita [4]3 years ago
3 0
The answer would be Haemoglobin.

The Haemoglobin is a red pigment found in RBCs of vertebrates that helps to transport oxygen to various tissues.
Vertebrate blood is bright red when it is oxygenated and dark red when it is deoxygenated. Some animals such as crustaceans or mollusks, use haemoglobin to carry oxygen instead of hemoglobin.

Hope This Helped!

Imagine these two elements, element A and element B are solids. The two elements are poured into a beaker and mixed. Illustrate
Kryger [21]

Chromatography is a simple technique in principle, it remains the most important method for the separation of mixtures into its components. It is quite versatile for it can be used to separate mixtures of solids.

Explanation:

  • The two elements of chromatography are the stationary phase and the mobile phase. There are many choices of stationary phases, some being alumina, silica, and even paper.  The mobile phase, in liquid chromatography, can also vary.  It is often either a solvent or a mixture of solvents and is often referred to as the eluant.
  • A careful choice of eluting solvent helps to make the separation more successful.  The mixture is placed on the stationary phase.  The eluant passes over the mixture and continues to pass through the stationary phase carrying along the components of the mixture.
  • Chromatography is used in industrial processes to purify chemicals, test for trace amounts of substances, separate chiral compounds and test products for quality control. Chromatography is the physical process by which complex mixtures are separated or analyzed.
  • Chromatography is based on the principle where molecules in mixture applied onto the surface or into the solid, and fluid stationary phase (stable phase) is separating from each other while moving with the aid of a mobile phase

A Paramecium has an internal sucrose concentration of 0.040 M, a glucose concentration of 0.035 M, and a fructose concentration
Nadusha1986 [10]

Answer:

<u>c. Sucrose and glucose</u>

Explanation:

The paramecium is a large, single-celled microbes, surrounded by a plasma membrane. Simple diffusion occurs in cells across plasma membranes, as a form of passive transport. In diffusion, solutes move from regions of high concentration to regions of low concentration across the plasma membrane.

Here, the internal environment has higher concentrations of sucrose and glucose, but lower concentrations of fructose, thus the solutes will move along their concentration gradient, to where the concentrations are lower. In order for the fructose molecules to move out of the cell, the molecules have to move against their concentration gradient - a process requiring energy known as active transport.

You place an inoculum of your bacterium on a glass slide and add a drop of hydrogen peroxide reagent. Promptly you see bubbles a
marissa [1.9K]

Answer:

The correct answer is A) Biochemical test

Explanation:

In microbiology biochemical test is used to examine the metabolic activities performed by bacteria to identify that microorganism. So in biochemical test enzymatic reaction of cell is usually investigated because there is difference in enzymatic activity of different species of bacteria.

For example, catalase test that is used to differentiate between catalase-positive and catalase-negative bacteria is an example of biochemical test. Catalase-positive bacteria have the catalase enzyme that breaks hydrogen peroxide into water and oxygen which is confirmed by bubbles that appear on glass slide.

Catalase negative bacteria do not form bubbles when they are put in hydrogen peroxide which shows that they lack catalase enzyme. So the right answer is A.
