Answer:
Algae are classified based on the
1. type of chlorophyll and secondary pigments
2. method of food storage
3. composition of cell wall
Explanation:
Algae can be classified on the basis of chlorophyll or other secondary pigments. For example, green algae have chlorophyll a and b. Brown algae possess chlorophyll a, c, carotenoids and xanthophyll pigments. Red algae possess a red pigment called r-phycoerythrin.
Other characteristics on which algae can be classified are their mode for storing food and the composition of the cell wall.
If its chemistry:
Hg: Mercury/Transition metal
Ni: Nickel/Transition metal
Ti: Titanium/Transition metal
There must be an abundance of food space and water or a lack of predators
I think that these are the answers
is the least dense planet in the solar system
has captured asteroids in its orbit
is the most massive planet in the solar system
Answer:
The prime function of the GTPase activity of the G-alpha protein is to perform the hydrolysis of the attached guanosine triphosphate or GTP. Upon combination with the GTP, the G-alpha protein becomes activated, and when hydrolysis of GTP takes place to guanosine diphosphate or GDP, the G-alpha subunit becomes inactivated.
Therefore, the activity of the GTPase provides the G protein-coupled signaling mechanism's regulation. In case, if the mutation takes place within the gene encrypting the G-alpha subunit, then the inhibition of GTPase activity occurs, which would eventually result in the following outcomes:
1. The stimulation of the signaling pathway may take place for a prolonged time duration, eventually causing an unwanted differentiation of the cell.
2. There would be a spontaneous enhancement in the concentration of cyclic-AMP within the cell.
3. The activation of the G-alpha subunit would take place for a prolonged time duration.
