Answer:
Heterotroph
Explanation:
Hi, According to what I understand, the term is heterotroph, not hetrotrop [Tropism is concerned with how organisms react to a certain stimulus]
The word "heterotrophy" refers to organisms that do not synthesis their food or carbohydrates in the presence of photosynthetic pigment using CO2, water, or solar energy. With the exception of Euglena, they cannot synthesis their food or carbohydrates (it is unicellular and contains photosynthetic pigment). Carnivores, herbivores, etc. are heterotrophs.
A nerve cell is a cell that travels in a nerve bacilcly it is neuron and it transmits signals to the brain to do something so if we want the wave our hand the nerve cell/neuron transmits signals to the brain.
In order to move molecules against the concentration gradients, the cell must have the advantage of Creates energy
<u>Explanation:</u>
When a solute is concentrated to a particular area it is called as concentration gradient. The law of thermodynamics well explains that a molecule moves from area of higher concentration to lower concentration.
If a molecule moves against the concentration gradient it is called as Active transport. For this process to happen the cell needs to energy efficient.
Energy is been released and it is stored in the form of bonds between the atoms during active transport. To maintain the proper balance in the molecules and the balancing of ions active transport is essential.
Next time remember to put in the option of the question, luckily for you I can see trough computers. If I'm correct the answer to your question is C. I can't be completely right without any sort of picture though.
Answer:
The main difficulties of X-ray crystallography include:
1. It is very difficult to obtain crystals with high diffraction quality and proper size.
2. Phase analysis. In theory, X-ray crystallography technology has no requirement for the molecular weight of protein, and can obtain any high-resolution structure at the atomic level of protein. Because some proteins are very difficult to crystallize, or the quality of crystallization is very poor, there is no diffraction or only very low resolution diffraction data, which limits the X-ray crystallography analysis of protein structure.
