Answer;
Arrangement of events in stellar formation;
C) The Big Bang occurs.
B) Pockets of elements in higher concentrations begin experiencing greater gravitational force.
A) Hydrogen atoms shed their electrons and fuse together to form larger helium atoms.
D) the glass clouds begin reducing in volume, which leads to increase in density, pressure, and temperature.
Explanation;
-Stellar evolution is the process by which a star changes over the course of time. All stars are born from collapsing clouds of gas and dust, often called nebulae or molecular clouds.
-Stars are born out of the gravitational collapse of cool, dense molecular clouds. As the cloud collapses, it fragments into smaller regions, which themselves contract to form stellar cores.
<h2>C) option is correct </h2>
Explanation:
- The spinal cord has numerous groups of nerve fibers going towards and coming from the brain
- These have been collectively called the ascending and descending tracts of the spinal cord, respectively, these tracts are responsible for carrying sensory and motor stimuli to and from the periphery (respectively)
- The ascending tracts transmit sensory information from the sensory receptors to higher levels of the CNS
- The descending tracts originate from different cortical areas and from brain stem nuclei
- The descending pathway carry information associated with maintenance of motor activities such as posture, balance, muscle tone, and visceral and somatic reflex activity
I would say that the given statement is false. Overexertion in extremely hot temperatures does not help the body to cool itself. <span>Overexertion in hot weather or working in hot, poorly ventilated or confined areas can increase your risk of heat stress. Hope this answers the question. </span>
Answer:
The sun takes an integral role in the photosynthesis stage of the Carbon Cycle. Photosynthesis refers to the process by which plants take in carbon dioxide and water (the products of respiration), and convert it to oxygen, powered by the energy of the sun.
Explanation:
Answer:
A lethal mutation, thereby the resulting phenotype is not observed
.
Explanation:
Lethal mutations are the result of genomic changes that may be lethal in certain conditions. In genetic research, this type of mutation has shown to be very useful in analyzing gene function (i.e., genes whose protein products are key for the survival of the organism in question), and they are perfect gene markers. In bacteriophages, for example, temperature-sensitive mutants of phage T4 that can not grow at temperatures higher 42°C have been identified (Edgar & Lielausis 1964).
