severe anemia may trigger an adaptive conversion of:

Answers

Severe anemia may trigger an adaptive conversion of yellow bone marrow to red bone marrow.

Anaemia is defined as the decrease or the reduction of the oxygen carrying content of the blood which are the red blood cells.

These red blood cells and other blood cells which include the white blood cells and the platelets are produced in the body by the bone marrows by a process called haemopoiesis.

The bone marrow is divided into two:

yellow bone marrow andred bone marrow.

The red bone marrow is made up of stem cells which can be converted to red cells when the need arises while yellow bone marrow is made up of fat.

During health conditions such as anaemia, there is increase in the need of red blood cells by the body.

There is usually the conversation of yellow bone marrow to red bone marrow to compensate for the increased demand of red blood cells.

This conversation is called an adaptive conversation.

Therefore,Severe anemia may trigger an adaptive conversion of yellow bone marrow to red bone marrow.

which molecule do indole positive bacteria cleave to form indole

Answers

In indole-positive bacteria, Tryptophan is used to form indole. This reaction is catalyzed by a tryptophanase enzyme.

Tryptophanase or tryptophan indole-lyase is an enzyme that catalyzes the reversible beta-elimination of Tryptophan to form indole.

Tryptophanase is present in many Gram-negative bacteria.

The indole-positive bacteria include Escherichia coli, Haemophilus influenzae, Aeromonas hydrophila, A. punctata, Bacillus alvei, Klebsiella oxytoca, etc.

On the other hand, the indole test is a test used to determine the ability of bacteria to convert tryptophan into indole.

A typical eukaryotic cell has enough available ATP to meet its needs for about 30 seconds. What is likely to happen to an individual when they exhaust their ATP supply? ATP will be transported into the cells from the circulatory system. Catabolic processes will be activated to generate additional ATP. The athlete will have to sit down and rest. Anabolic processes will be activated to produce new mitochondria.

Answers

Catabolic processes will be activated to generate addition ATP. (I think its like when you burn good carbs and then you start to burn bad carbs that don't give you sufficient energy)

In the case of given scenario, the catabolic processes will be activated to generate additional ATP. The correct option is B.

What are catabolic processes?

Catabolic processes are the set of enzyme-catalyzed responses that disintegrate or degrade fairly large molecules in living cells.

Part of the chemical energy emitted during catabolic processes is conserved as energy-rich compounds such as adenosine triphosphate [ATP].

Thus, the correct option is B.

By their chemical compositions. By their physical properties.

Thus, the correct options for this question are A and B.

What are the different layers of the earth?

The structure of the earth is generally categorized into four major layers. They are as follows:

The crust.The mantle.The outer core.The inner core.

Each of the above-mentioned layers has unique chemical composition. Apart from chemical composition, the physical state is also important when describing the different layers of the earth. The concentration of iron is found to be the highest in the core regions along with a little bit of nickel.

Therefore, chemical composition and physical properties are the two parameters that are used to define the different layers of the earth. Thus, the correct options for this question are A and B.

What would happen if a similar diffusion/osmosis experiment were performed with plant cells instead of animal cells? would plant cells behave in the same manner?

Answers

Answer: because plant and animal cells can tolerate different concentrations of water.

Explanation:

Image result for What would happen if a similar diffusion/osmosis experiment were performed with plant cells instead of animal cells? would plant cells behave in the same manner?

Osmosis affects plant and animal cells differently because plant and animal cells can tolerate different concentrations of water. ... However, plant cells need more water than animal cells, and will not burst in a hypotonic solution due to their thick cell walls; hypotonic solutions are ideal for plant cells.

When diffusion and osmosis experiments are performed on a plant cell, the plant cell will expand because it has a rigid cell wall, which prevents it from bursting.

What are osmosis and diffusion?

Osmosis is the process when molecules move from a lower concentration area to a higher concentration area.

Diffusion is the process, in which the molecules move from higher concentration to lower concentration.

When osmosis happens to the animal cells, it will fully fill and burst.

But, it will not happen in the plant cell, because it contains a cell wall.

Thus, When diffusion and osmosis experiments are performed on a plant cell, the plant cell will expand because it has a rigid cell wall, which prevents it from bursting.

Por qué el melanismo industrial es un tipo de selección direccional

Answers

El melanismo industrial es el fenómeno genético por el cual lepidópteros que viven en zonas industriales tienen un color oscuro. Este fenómeno se debe a que la selección natural favorece un determinado genotipo.

La selección natural es el principal mecanismo por el cual las especies y los organismos evolucionan (cambian) para adaptarse a su ambiente.

La selección natural se define como la supervivencia y reproducción diferencial de los individuos mejor adaptados a su ambiente.

Este proceso (selección natural) tiende a modificar las frecuencias de génicas (alélicas) y genotípicas las cuales determinan los rasgos adaptativos a lo largo de las generaciones.

La selección direccional es un tipo de selección natural que tiende a favorecer a un sólo alelo a lo largo del tiempo.

En el melanismo industrial, los lepidópteros (polillas) que expresan el alelo que codifica para el rasgo fenotípico 'color oscuro' se ven favorecidos porque esta característica les permite mimetizarse en un entrono ambiental oscuro causado por la polución ambiental de zonas industriales.
