Answer:
Empirical evidence of his ideas
Explanation:
The scientific process involves the formulation of hypotheses that enable to answer questions about the real world, and then to carry out experiments or observations that are used to confirm (or reject) such predictions. In the last 160 years, Darwin's ideas on 'descent with modification' have constantly been subjected to experimental assessment, and obtained data confirmed his observations. For example, molecular evidence based on the DNA and RNA -which constitute the genetic material of all living organisms- has shown the conservation of this process. In consequence, molecular evidence has been used to construct 'evolutionary' phylogenetic trees from DNA/RNA sequences. Moreover, evidence in genetics has shown the critical role played by mutations in the mechanism of natural selection proposed by Darwin, thus also confirming his theories. These are only some examples, and supporting evidence confirming Darwin's ideas has been collected from different research fields ranging from ecology to molecular biology.
Answer:
For example, addition of an orange chromic acid reagent to some compounds causes the chromium reagent to change to a blue-green color (Figure 6.37a). This is considered a "positive" test result, and in this case indicates the presence of a functional group that can be oxidized (alcohol or aldehyde).
The answer is A
The abstinence violation effect
<span>This effect
occurs when an individual, having made a personal commitment to abstain
from using a substance or to stop engaging in some other unwanted behavior, has
an initial lapse whereby the substance or behavior is engaged in at least once.
Some individuals may then proceed to uncontrolled use. It occurs when the
person attributes the cause of the initial lapse to internal, stable, and
global factors within.</span>
Answer:
Whisk ferns
Explanation:
Non-vascular Plants. The non-vascular plants include mosses, hornworts and liverworts, and some algae. They are generally small plants limited in size by poor transport methods for water, gases and other compounds. They reproduce via spores rather than seeds and do not produce flowers, fruit or wood.
C the trait is passed on genetically to the next generation
