The right option is; C. cinder cone, a pyroclastic flow with no explosion
Basaltic magma is a fluid rock material produced from basalt and it has high amounts of iron and magnesium, and low amounts of silica. Basaltic magma is formed within the earth when a part of the earth's mantle is melted. Basaltic magma produces three different types of lava or volcanic deposits which are scoria, ash or cinder, and lava flows.
Answer:
The reflex arc follows this sequence of events
1. sensory receptor activation
2. sensory neuron activation
3.information processing
4. motor neuron activation
5. effector response
Explanation:
Reflex arc is the pathway of nerves during a reflex action. An example of a reflex arc is when we accidentally touch a hot object. First, the receptor in the skin detects a stimulus in this case the change in temperature. Second, the sensory neuron transmit the electrical impulses to the Central Nervous System for information processing. Then relay neurons connect sensory neurons to motor neurons. Third, motor neurons sends electrical impulses to an effector wherein the effector produces a response ( muscle contracts to move the hand away from the hot object. This happens in a split of seconds.
Answer:
All plasmids we manufactured are free of animal-derived materials and can contain low levels of endotoxin (<100EU/mg, on request). This process is designed to meet our customers’ diverse downstream applications such as transfection, antibody preparation, vaccine, and gene-therapy research, etc.
Answer:
The correct answer will be option - D.
Explanation:
Slime moulds are the fungus-like protists which bear a structure called sporangium which produces spores. The sporangium is produced in fungi as well due to which these protists are called fungus-like. Although both produce sporangium but they are not closely related, rather they are distantly related organisms.
The appearance of a sporangium in both indicates that they had faced the same conditions due to which they both showed the same adaptation by producing the same structures performing the same function. In evolutionary terms, this is an example of convergent evolution.
Thus, option D is the correct answer.
