Answer:
Oxidize organic compounds AND use organic compounds as terminal electron acceptors. (Ans. E)
Explanation:
Anaerobes are the organism that does not require oxygen for their growth. The anaerobes are subdivided into three main classes:
1) Obligate anaerobes: These organisms use anaerobic metabolism to grow and killed in the presence of oxygen. Obligate anaerobe examples are Clostridium and Propionibacterium.
2) Facultative anaerobes: These organisms prefer to grow using aerobic metabolism processes and switch to anaerobic metabolism in the absence of oxygen. An example of facultative anaerobic bacteria is Lactobacillus.
3) Aerotolerent anaerobes: These organisms use anaerobic metabolism to grow and can survive in both conditions (oxygen and oxygen-free environment).
Anaerobic bacteria, oxidize organic compounds rather than oxygen & use organic compounds as terminal electron acceptors. Anaerobic bacteria release hydrogen sulfide gas as they decompose algae in the water. This process is also known as Anaerobic Respiration, in which formation of ATP without oxygen.
Answer:
Adaptive management requires environmental work. In particular, design, management and monitoring must be integrated in order to systematically test assumptions, to adapt and learn.
Explanation:
Two phases are described: the set-phase during which the main components are created and the iterative phase during which they can be integrated during the sequential decision process. The implementation is possible for adaptive management. The implementation process has five systemic components, namely the involvement of stakeholders, management goals, management action capacity, predictive models and monitoring plans. The iterative stage uses these elements in a continuous process of learning and management based on the learned system structure and function.
Set Phase:-
1-Stakeholder participation Ensuring the engagement of stakeholders to run the organization for the duration of its operations. 2-Objectives In order to direct the decisions and assess management performance, define simple, measurable and understood management targets over time.
3-Action on management Identify a set of potential decision-making management actions.
4-Models Describes models characterizing different ideas about the operation of the system (hypotheses).
5- Prepare for the surveillance of the resource state and other primary resource characteristics Design and implementation.
Iterative phase:-
6-Decision making Leadership actions based on leadership priorities, capital and comprehension.
7-Tracking follow-up Using system response tracking for control interventions. Tracking.
8-Analysis Enhance understanding of the nature of resources by comparing improvements to resource status expected and observed.
9-Process of erasure from step-6
C. BAT can detect sound at a frequency of 67,000 Hz. Its frequency range is 2,000 - 110,000 Hz67 - 45,000 Hz.
An elephant's frequency range is 16-12,000 Hz.
A tree frog's frequency range is 50 - 4,000 Hz
A dog's frequency range is 67 - 45,000.
Bats have very sensitive hearing to cope with their nocturnal activities. Since the feed at night time, they have difficulty in seeing their prey.
Bats navigate and locate their prey using echolocation. Echolocation is a method where bats produce a very loud sound and assess the sound's echo. The echo has two types of frequency. Constant frequency, used to detect object, and Frequency modulated, used to assess the distance of the object. Bats then know the presence of its prey as well as its location.
Answer:
True.
Explanation:
The earth system is itself an integrated system, but it can be subdivided into four main components, sub-systems or spheres: the geosphere, atmosphere, hydrosphere and biosphere. These components are also systems in their own right and they are tightly interconnected.
Answer :Four characteristics were to be used for the classification of all viruses:
Nature of the nucleic acid in the virion.
Symmetry of the protein shell.
Presence or absence of a lipid membrane.
Dimensions of the virion and capsid.
