Answer:

Most archaebacteria is autotrophic but some heterotroph organisms are also present.

Explanation: Autotrophic organisms are those which make their own food while heterotroph cannot. Archaebacteria are unicellular and prokaryotic organisms which belongs to the kingdom monera. Unicellular organisms are those which is made of single. Single cell perform all body functions such as respiration, digestion and reproduction etc. Prokaryotic means lack of nuclear membrane around the nucleus and absence of mitochondria, ribosome, lysosomes and endoplasmic reticulum.

Populations that exhibit logistic growth still exhibit exponential growth. This statement is:
adoni [48]

Answer: Option B (True)

Explanation: The statement can only occur in different populations of the same organism. The two growth strategies happens in different modes.

Firstly, logistic growth occurs when the resources available in the habitat (i.e organism’s niche) are limited to satisfy the whole population and this allows the organisms of the same species to grow rapidly until it reaches the point the resources can circulate, the carrying capacity.

While exponential growth occurs when there's abundance of resources for the population and allows growth of population beyond the carrying capacity, which results to overshoot of population in later stage of growth.

Secondly, in logistic growth population rarely crash but in exponential growth, population crashes due to mortality (often by predation, disease outbreak and etc) when there's overshoot of population beyond the carrying capacity.

Note: Population refers to the total number of organisms of the same species inhabiting a geographical area at a particular time.

BabaBlast [244]
1)magnification goes by 10x (read 10 times), 100x,1000x and some goes 10,000x 

2)Always focus first using lowest power possible first, switch to medium power (100x) after it's focused on low power(10x), on 100x, use the small knob to focus it more. DO NOT touch the bigger nob when in medium or high power. Switch to high power (100x) when it is focused on medium power, again focus again using the small knob on high power. 

3) So it doesn't gather dust and fog up the lense? that one should be self explanatory

  • amygdala.
  • thalamus.
  • basal ganglia.
  • hypothalamus.
  • cingulate gyrus.
  • hippocampus.

A population of fruit bats faces a food shortage when the fruit trees they depend on for food begin to die from disease. What ty
ss7ja [257]

The limiting factor is in the environment rather than the age, since the bats growth is only limited by the fruit trees they feed on. This follows the concept of carrying capacity of an environment, so this is best modelled by logistic growth.

so the answer is logistic growth
