Hormones derived from amino acids can cause different effects in different cells depending on the type of cell and its signal transduction pathway.
An arrangement of chemical reactions in a cell that happens when a particle, for example, a hormone, joins to a receptor on the cell layer. The pathway is really a course of biochemical responses inside the cell that eventually achieve the objective particle or response.
The answer that contributes to Mars's cool temperatures is the third choice - Its thin atmosphere and distance from the Sun.
Mars is relatively distant from the Sun - it is the fourth planet away from the Sun which means that it can be quite cold there given that its atmosphere is quite thin which means that the cold is quite present there.
Answer:
The correct answer is option-C
Explanation:
Anastosomes is a connection between the two interconnected tubular structures like in the loops of intestine or the blood vessels.
The anastomy between the blood vessels is known as the circulatory anastomosis. The connection is formed between the arteries and arteries or between veins and veins or between arteirs and veins.
The anastosome connections forms the bypass route for the flow of blood if one pathway of blood id blocked.
Thus, option-C is the correct answer.
The first step in the development of a complex organism is the establishment of a pattern of cells with different states that can differentiate along different pathways. … [P]atterning processes require signalling between and within cells, leading ultimately to gene activation or inactivation. Such a process can lead to reliable patterns of cell activities only if all the cells have the same set of genes and obey the same rules<span> [</span>
Answer:
The Quantum Model of the Atom 1927
Explanation:
It is the most accurate model of the atom but I don't know about the easiest to visualise. Soz :(
