Suppose a team of researchers becomes the first to synthesize organic molecules out of inorganic molecules. The conditions to wh

ich they subject their samples of inorganic molecules include periods of intense sunlight and radiation followed by periods of extreme cold—temperatures near that of outer space. After many such cycles of intense energy bombardment and cold, the researchers observe the development of organic molecules. If the findings of the researchers prove to be accurate, which features of their findings might challenge the primordial soup theory? Which aspects of the primordial soup theory would need to be adjusted in light of this new evidence? Why

Answer:

Primitive Earth where life emerged was subjected to extreme conditions  

Explanation:

The origin of life is still an issue of intense debate today, although most researchers believe that life emerged from primitive organisms generated by the synthesis of organic compounds in early Earth. In line with this theory, it has been shown that membrane-forming compounds can be formed in extreme conditions (i.e., UV rays, extreme temperature, etc). It is believed that such conditions recreated in a laboratory were similar to the early Earth about 3,900 million years ago, thereby supporting the idea of the 'primordial soup theory' proposed by John Burdon Sanderson Haldane in 1929.

Effectus [21]

Answer:

A central nervous system is consist of brain and spinal cord. The brain is made of the cerebrum, cerebellum, and brain stem.

The parts of the central nervous system involved in given behaviors are as follows:

  • <u>Listening to music:</u> The cerebrum in the brain is responsible for the behaviour of listening music as it functions for auditory stimuli (temporal lobe).
  • <u>Realization of being thirsty:</u> limbic system in brain is responsible for the regulation of thirst.
  • <u>Feel that soda is no longer cold: </u>Hypothalamus in brain controls the sense of temperature felt by the body.
  • <u>Decide to invite a friend over: </u>The cerebrum functions for thinking and decision making.

liberstina [14]

Answer:

She left Ligase enzyme out of the mixture.

Explanation:

DNA replication is the process of formation of new molecules of DNA from the existing one. This process occurs in semiconservative way i.e each new strand consist of one newly synthesised strand and one old parent strand that act as template for the formation of new strand. replication on one strand occurs continuously from 5 prime to 3 prime but on other strands it occurs discontinuously from 5 prime to 3 prime because DNA polymerase moves only in one direction from 5 prime to 3 prime. Hence in discontinuous strands gaps remained. These gaps are filled by Ligase enzyme.

Requirements for DNA replication:

DNA replications needs

Primers

DNA Polymerase enzyme

DNA helicase enzyme

Single nucleotide binding protein

dNTPs

and Ligase enzyme.

Correct choice:

She left Ligase enzyme out of the mixture.

In a biological reaction involving an enzyme, what does the substrate bind to? the active site of another substrate the inactive
alexandr402 [8]

Answer: The part of the enzyme where the substrate binds is called the active site (since that's where the catalytic “action” happens). ... Thanks to these amino acids, an enzyme's active site is uniquely suited to bind to a particular target—the enzyme's substrate or substrates—and help them undergo a chemical reaction. To catalyze a reaction, an enzyme will grab on (bind) to one or more reactant molecules. These molecules are the enzyme's substrates. In some reactions, one substrate is broken down into multiple products. ... The products then leave the active site of the enzyme.
