DNA and RNA are different from structures, functions, and stability. DNA has four nitrogen bases those of which include adenine,thymine, cytosine, and guanine. In RNA, instead of thymine it is replaced with uracil. DNA is double stranded while RNA is single stranded
The given statement is True.
<u>Explanation:</u>
The Charles Darwin developed the theory called Darwinism theory of evolution. The theory states that all the species of the organisms arises and developed through the small, inherited variations in the organisms that increase the individual ability to complete the survive and reproduce.
The individual species are not having identical traits that are passed from the generation to generation. The offspring are born that can survive, only the survive of the completion for resources will reproduce; he describes how the species can change in shape and character through the selective breeding.
Answer:
B
Explanation:
<em>The correct answer here would be that </em><em>it can be injected by a virus.</em>
Since a virus operates by taking over the genetic system of the host and uses its replication, transcription, and translation to make virions or viral particles through the lytic or lysogenic life cycle. In the process, if the virus is utilized as a vector to carry a foreign DNA, the DNA is introduced into the genome of the bacteria. This is exactly what happens during the process known as transduction.
<em>The correct option is, therefore, </em><em>B.</em>
Answer:
This question lacks options, options are:
A) cerebral cortex.
B) basal nuclei.
C) sensory pathways.
D) motor pathways.
E) All of the answers are correct.
The correct answer is E.
Explanation:
The cerebral cortex processes and filters its information before passing the most relevant aspects to other regions of the brain. Some of these brain regions, in turn, send information back to the cortex. These loops, known as 'feedback systems', are considered essential for the functioning of cortical networks and their adaptation to new sensory information. Neural circuits must first assess the importance of incoming sensory information and then refine how it is processed in the future. Positive feedback, triggered with the purpose of amplifying the response to the initial stimulus, can be compared to a chain reaction or a vicious circle. Few are the functions regulated by this mechanism; rather it is triggered in pathological situations. It is the system by means of which the organism very rarely regulates any of the bodily functions under normal conditions, making the initial stimulus to be maintained and even increased. This type of mechanism is predominantly present in pathological situations: Its constitutive elements are: stimulus, receptor, afferent pathway, integrating center, efferent pathway, effector and response. The response does not have the ability to satisfy the initial stimulus.
