Answer:
Dead plant matter
Explanation:
Saprotrophs feed by a process known as absorptive nutrition, in which the nutritional substrate (e.g., dead organism or other nonliving organic matter) is directly digested by a variety of enzymes that are excreted by the saprotroph.
Answer:
D. Eukaryote
Explanation:
An organism that has membrane-bound organelles will have more complex organelles like mitochondria, Golgi apparatus, and ER. These are known as Eukaryotes. Additionally, they will have a nucleus that has the DNA coiled inside. Prokaryotes do not have membrane-bound organelle and the DNA floats in the cytoplasm. Most plants and animals are eukaryotes and all multicellular organisms are too.
Answer:
R = 480 Ohm
Yes, the current is steady since the power supply is a constant 12V (comming from the battery).
Explanation:
U=I*R
R = U / I
U = 12 V
I = 0.025 A
R = 12 / 0.025
R = 480 Ohm
Answer:
Option (2).
Explanation:
Ecological succession is the change in the ecological community of the species with respect to time. Two types of the succession are secondary succession and primary succession.
The ecological succession includes various transitional stages before reaching to the climax community. The simple species acquires first and then the climax species is reached at the end of the succession. Different changes are involved in the formation of climax community.
Thus, the correct answer is option (2).
<h2>
Answer:</h2>
<u>Blood clotting</u> is a positive feedback.
<h2>
Explanation:</h2>
All the physiological process occurring in the body are monitored by two types of mechanism called negative feedback and positive feedback.
Positive feedback is the reaction which occurs with the feedback from the actions the system has performed. The blood clot occurs with palette formation which is regulated with the blood lose (continuous feedback).
Negative feedback is a reaction that is the invert of the change distinguished, meaning it capacities to decrease the change. A change is recognized by a receptor and an effector is made to incite a contrary impact which facilitates further reaction.
The physiological process such as shivering, sweating and digestion are examples of negative feedback.
