<h2>Rates of Population Growth</h2>
Explanation:
- <em>Growth is precisely defined for microbes as increment in number of cells, not size</em>
- Development rate is change in cell numbers per unit time. Age time is the time it takes for a cell to double. Also called doubling time.
- Development rates allude to the rate change of a particular variable inside a particular time span and given a specific setting.
-
r = (births-passings)/populace size or to get in rate terms, <em>simply increase by 100</em>
- The populace is so a lot greater, a lot more people are included. In the event that a populace develops by a consistent rate for every year, this inevitably indicates what we call exponential growth..
Answer: a crack forms, magma pushes upward, magma hardens, rock moves outward.
Answer:
A: Natural selection would likely have selected for humans with little skin pigmentation
Explanation:
Sunlight/UV radiation has been discovered to be an inducer of immediate pigment darkening or melanin production. Hence, if a sunlight/UV radiation shield is is constructed to limit the amount of radiation that reaches the earth, after a while, this might become a selection factor.
Natural selection would likely have selected for humans with little skin pigmentation, those that are able to successfully adapt to the effects of limited sunlight/uv radiation. Humans who are not able to adapt to limited sunlight/uv radiation eventually get replaced in the population by those that are well adapted.
<em>According to theory of natural selection which was proposed by Darwin,</em> organisms with heritable traits that enable them to adapt to changes in an environment will survive more and produce offspring which are also able to survive. This eventually leads to eventual dominance of well adapted organisms in the environment over those that are not able to or weakly adapted.
<em>The correct option is A</em>
Answer:
The correct answer will be-true
Explanation:
<em>E.coli</em> is a prokaryote which is used by the geneticist and the molecular biologist to study the basic mechanisms of the molecular biology like DNA replication, gene expression and others.
This has been made possible as the<em> E.coli</em> is a simple organism which can be easily cultured in the laboratories.
Also, the small size of the bacterium and the small size of the bacterial genome which is 4.2 million bp provides an advantage to study the concepts of the molecular biology.
Thus, true is the correct answer.
