What are the smallest blood cells in the frog?

Biology
1 answer:
Tamiku [17]3 years ago
4 0

Answer:

Unlike typical mammalian red blood cells, those from amphibians, such as frogs, contain a DNA-bearing nucleus that is visible in the center of the cell. The circulatory system of amphibians is rather unusual, their hearts having three chambers, two atria, and a single ventricle.

NegativePositive

Positive

The design of the amphibian circulatory system is curious because blood accumulates oxygen in the lungs and is then returned to the heart before being pumped into the rest of the circulatory system. Therefore, a mixing between oxygenated and deoxygenated blood occurs as blood returning to the heart from the lungs is mixed with incoming blood from the body. Frogs handle this situation by having a very slow metabolism and by absorbing some oxygen through their skin. In addition, the ventricle does have some directional control over the distribution of the blood.

Negative

The presence of a nucleus in amphibian red blood cells allows researchers easy access to large quantities of amphibian DNA. Frog blood has both a solid and a liquid portion. The liquid plasma carries solid elements such as red and white blood cells. Blood can be collected from frogs and the red blood cells isolated by centrifugation. After removal of the residual plasma, purified cells can be treated with specific enzymes and detergents to digest the cellular envelope and release DNA from its protein complex. The DNA is then useful for scientific studies and experiments.

Comment on why do you think cells prefer to use carbohydrates as a source of energy before they use fats and proteins.
kompoz [17]

Answer:

This can be explained  based on structure, and on metabolisms of  carbohydrate.

Explanation:

Carbohydrate has a relatively simple structural composition than the  either protein or fatty acids. The C, H and Oxygen molecules are of  relatively fewer in number and few  chains than fats and protein.Thus  cells will spend less energy to break bonds(catabolisims) among these molecules during cellular respiration  pathways  to trap the energy.

In addition glucose the end products of carbohydrate did not need any processing before it enters glycolysis, Kreb's Cycle and oxidative phosphorylation pathways to generate energy for the cells.

Conversely, for protein to be used it has to be first deaminated(removal of amino acid) by the liver  before it enters glycolysis,while fats needs to  be broken down and undergo beta oxidation   with the long chains removed  before it can  form acetyl CoA. Therefore cells will prefer few steps, less endergonic  pathways of glucose than longer more endergonic amino acids  and fatty acid pathways.

Furthermore, glucose can be used in cellular respiration to  produce energy either aerobically or anaerobically, while fats can only be used anaerobically. Therefore, since cells usually prefer to thrive in aerobic conditions they  breakdown glucose easily during this period, and when lack of oxygen occurs they switched to anaerobic, Thus, the versatility of glucose to oxygen concentration makes glucose a better choice. Besides if fats was used anaerobically, ketone bodies build up which may be toxic to the cells.

A graduated cylinder contains 10mL of water. A rock is dropped into the cylinder and the water level rises to 17mL. What is the
Travka [436]

Answer:

<h3>7 milliliters or 7 cubic centimeters</h3>

Explanation:

1 cubic centimeter = 1 milliliter

You can measure the volume of a rock using cubic centimeters because rocks do not have a defined shaped so you have to use water displacement to find the volume of a rock. If you had a defined shape there are different methods but for an undefined shape( rocks) you use this method.

To solve all you have to do is know how much there was in the container without the rock then how much there was with the rock. Then you take the total and subtract the original measurement you had.

17-10=7 mL or 7 cubic centimeters
