Answer:
Bond energy is the amount of energy that breaks a bond. Energy is added to break bonds and energy is also released when bonds form. ... In an exothermic reaction, the products have (more or less) energy than the reactants.
Explanation:
<h2>What is a feedback mechanism?</h2>
A feedback mechanism is a physiological regulation system in a living body that works to return the body to its normal internal state, or commonly known as homeostasis. In nature, feedback mechanisms can be found in a variety of environments and animal types. Feedback occurs when outputs of a system are routed back as inputs as part of a chain of cause-and-effect that forms a circuit or loop. The system can then be said to feed back into itself.
Examples:
- Menstrual cycle. At the beginning of the menstrual cycle, the ovaries release the hormone estrogen. The estrogen acts as a stimulus for the positive feedback loop. ...
- Childbirth. Figure: Normal childbirth is driven by a positive feedback loop.
Normally, people produce about 100 billion white blood cells a day. ... However, an increase in the number of white blood cells is also caused by cancers of the bone marrow (such as leukemia) or by the release of immature or abnormal white blood cells from the bone marrow into the blood.

Answer:
250.
Explanation:
A test cross would cross the genotype AaBb with homozygous recessive genotype aabb. The cross between AaBB x aabb would produce progeny in 1:1:1:1 ratio. So, the proportion of the progeny expressing both dominant traits (AaBb) is 1/4.
Therefore, out of the total 1000 offspring, 1/4 x 1000= 250 would express the dominant phenotype for both A and B genes.
