Question

1. What is the difference between autopolyploidy and allopopyploidy?

a) Autopolyploidy occurs randomly, wehreas allopolyploidy occurs only by genetic engineering.

b) Autopolyploidy results from an error in meiosis or mitosis within a species, whereas allopolyploidy results from the hybridization of two species.

c) Autopolyploidy always results in viable offspring, whereas allopolyploidy never results in viable offspring.

d) All of the above are true.

e) Only (B) and (C) are true

d)coniferous forest

3. In an ecosystem exposed to sunlight, the gross primary production of an ecosystem is

a) the amount of solar energy captured by primary producers via photosynthesis and converted to chemical energy in the primary producers.

b) the amount of chemical energy formed in primary consumers that was obtained from organic matter in primary producers.

c) the total amount of chemical energy present in an entire ecosystem (including ALL trophic levels of the ecosystem)

c) the world is fixed and constant

d) operation of natural laws produces constant change and improvement.

Answer 1

1.e) Only B and C are true.

The main difference is that the autopolyploidy is the containment of multiple sets of chromosomes that are derived from the same species whereas allopolyploidy is the containment of multiple sets of chromosomes that are derived from the different species.

2.b) tropical rainforest.

3.b)the amount of chemical energy formed in primary consumers that was obtained from organic matter in primary producers

4.d)human population growth

5.c) the world is fixed and constant
