What is “the balance of nature”? (use complete sentences)
alexandr1967 [171]

Given what we know, we can confirm that the "balance of nature" refers to a scientific theory about ecological homeostasis.

<h3>What does ecological homeostasis mean?</h3>
  • This refers to the idea of a perfect balance in an ecosystem.
  • It is the theory that all aspects of an ecosystem are and will remain balanced even if there are small changes.
  • This implies that any minor change in an ecosystem will be corrected.
  • This will happen through natural regulation mechanisms such as positive or negative feedback.

Therefore, we can confirm that the "balance of nature" is the scientific theory that all things in an ecosystem will remain balanced, meaning that if there is a small change, it will be corrected through some form of natural regulatory mechanism.

A competent bacterial strain with genes a, b, and c is transformed by a donor bacterial fragment. Cotransformation frequencies f
mina [271]

Answer:

a) Genes b and c are farthest apart.

Explanation:

Transformation occurs when a competent bacteria cell takes up genetic material from the environment. Usually a donor cell donates its gene fragment  which is then incorporated into the chromosome or plasmid of recipient bacterial cell.

Cotransformation occurs when two genes are taken up together by the recipient. The closer the genes lie to each other, more are the chances of them being taken up together. Contransformation frequency will be higher if two genes are close to each other. Here, cotransformation frequencies between three genes are given. Amongst them, the lowest frequency is 0.0064% which is present between gene b and c. Hence, gene b and c are the farthest apart.

WHEN is glucose created in the Calvin cycle?
Vsevolod [243]
<span> In the chloroplasts of green plants, molecular oxygen is created during the light-dependent reactions on the tetra-metallic manganese-containing active site of the O2-evolving complex of photosystem II when two (coordinated) water molecules are oxidized to yield a molecule of O2. Meanwhile, the Calvin cycle consists of the following intermediate products: RuBP --> 3PG --> BPG --> G3P --> DHAP --> FBP --> F6P --> G6P --> glucose. Thus glucose is produced only in the Calvin cycle, and oxygen only in the light-dependent reactions on photosystem II in thylakoid membranes.  hope this helps! sorry that is long.</span>
