Answer:
False.
Explanation:
Bacteria are the prokaryotic organism that lacks the well developed nucleus and the membrane bound cell organelle. The animal cells are the eukaryotic organisms.
Bacteria cells have cell walls that are made of the peptidoglycan layer. The cell wall of bacteria are important as it protect themselves from the extreme environment. The animal cells do not contain cell wall and they have plasma membrane only in their structure.
Thus, the correct answer is option (b).
Answer:
I can think of several reasons
Explanation:
- Not all the offspring will survive until they are old enough to propagate
- Disease and accidents will kill some mature individuals before they can produce six offspring
- Predators will kill the weak and infirm individuals
- Poachers will kill every elephant they can find for their valuable ivory
- The land has a limited carrying capacity. Each area has a limited amount of resources available, so the population will level off as it approaches this limit.
Answer:
The correct answer would be option D.
In any food web, the inorganic carbon from the atmosphere is incorporated into the organic matter by the process of photosynthesis.
Autotrophs perform photosynthesis and fix carbon obtained from carbon dioxide into the glucose or organic matter with the help of chlorophyll and in the presence of sunlight.
6 CO₂ + 6 H₂O → C₆H₁₂O₆ + 6 O₂
This is really basic, containing much on the history of cell biology. The cell theory, or cell doctrine, states that all organisms are composed of similar units of organization, called cells. The concept was formally articulated in 1839 by Schleiden & Schwann and has remained as the foundation of modern biology.
