Answer: It means to guide and regulate chemical and physical parameters to keep your body or environment in a constate state for proper functioning.

Explanation: This is called homeostasis. The body has systems in place to monitor its components such as cells, organs and any other molecule needed to maintain life and good health. The body needs to maintain its temperature at 37°C, pH of blood at 7.4, water balance, osmotic pressure, growth rate and tissue repairs whenever it dictates the need, danger of infection or injury.

All of these form an integral part of a healthy living organism and it needs to always be stable, regulated and monitored. This is called maintaining homeostasis.

The discarded theory of blending inheritance most closely resembles what inheritance

pochemuha

The discarded theory of blending inheritance most closely resembles incomplete dominance.

<h3>What is blending inheritance?</h3>

An antiquated biological notion from the 19th century is the concept of blending inheritance.
According to the hypothesis, children inherit any trait by averaging the values of their parents for that trait.
According to the theory of blended inheritance, an offspring combines the values of both parents for a given attribute.
As opposed to blended inheritance, particulate inheritance states that a child inherits individual units or genes from each parent.
Offspring thus combines the traits of both parents.
Incomplete dominance is the term used to describe phenotypic "blending" of two features, which implies that neither trait is truly dominant over the other.
The manifestation of phenotypic traits that are intermediate between those of the parents, such as pink flower color from red and white parents.
Inheritance was a now-discredited hypothesis that claimed children's genetic make-up was a pure admixture of their parents'.

Evolution is the

lina2011 [118]

Answer:

Evolution is the <u>biological process</u> that happens over time in a population, giving rise to new <u>species.</u> The theory of evolution states that all organisms alive on Earth today <u>have a common ancestor</u> which lived <u>years ago</u>.

Explanation:

Evolution is one of the fundamental reason of diverse life on Earth today. Principally, this process takes place by changes in genetic elements via mutations and crossing-over. The positive changes (mutations) allow the organism to develop better condition in order to survive in changing environmment. However, if the changes takes place at major scale, it also leads to the creation/development of new species. To explain this further, I have added a photograph where we can see how different organisms were evolved in the history of Earth.
