Answer:
True, by active transport
Explanation:
The influx and efflux of molecules through the cell membrane depend on the concentration gradient.
When the molecules down their concentration gradient that is from higher concentration to lower concentration are known as passive transport but sometimes the cell has to transport the ions against the concentration gradient.
When the ions move against the concentration gradient, they use energy in the form of ATP molecules and then transport the ions. This is known as active transport.
In the given question, since the sodium ions move inside the cell against the concentration gradient by the active transport.
Biomass might literally mean a biological mass, but it actually denotes sources that are burned to produce energy. Biomass is considered a renewable energy source. The primary one that has been used for thousands of years is wood; it is still widespread in many primitive areas and it is burned in old and new burners. Biofuels like ethanol from crops is another important source that has been on a rise. They are cheap and they are used a lot in developing countries. Finally, the burning of municipal waste is another source and many Nordic countries use it to produce energy and even some import waste to use as fuel.
The most direct way to different types of epithelium tissue is by the number of cell layers and by the shape<span> of the cells. As for the layers, they can be simple, if there is only one layer of cells, or stratified, if there is more than one layer of cells. Related to the shape of the cells it can be a squamous epithelium, a cuboid epithelium, a columnar epithelium, or transitional when the cell can adopt different shapes so that the epithelium can be stretched.</span>
Here is the answer to the given question above. tRNA or transfer RNA anticodon is more similar to DNA than to RNA in nucleotide sequence. The role of the tRNA is to carry amino acids. Hope this is the answer that you are looking for.
Answer:
Option (2).
Explanation:
The classification of the animals are done on the basis of similarity and differences among the individuals. The system of classification was first explained by Linnaean classification.
The most inclusive of the taxonomy level is kingdom that includes in the plants and animals in the separate kingdom. From the kingdom they are further classified into phylum then into the class, family and order. After the order the organisms are further classified into genus and the species is the least inclusive level of taxonomy.
Thus, the correct answer is option (2).
