Answer:
True
Explanation:
Sensory neurons are the neurons present in the nerves which can convert the external stimuli into an electrical signal and can transmit the signals from the organs to the central nervous system.
The structure of sensory neuron in pseudounipolar that is at one end it has dendrites and another end transmits the signals to the CNS.
The cell bodies (nucleus) of these sensory neurons are located in the structures called ganglia located outside the CNS.
Thus, True is the correct answer.
Answer: Only some of the organisms survive and reproduce.
Natural selection is a process of differential survival and reproduction in which organisms bearing favorable phenotypic traits survive in changing environmental conditions. Therefore, only some of the organisms survive and reproduce which have suitable phenotypic trait. For example a population of beetle bearing two colors red and green. The green colored beetles mimic the color of grass will remain undetected by birds and those with red color easily observed and detected by birds. Hence, only green beetles are favored for survival over red beetles.
Answer:
The DNA double helix unzips.
A strand of RNA is made from a strand of DNA.
The strand of RNA leaves the nucleus.
The strand of RNA moves to the ribosome.
A protein is produced.
Explanation:
During protein production, the messages in DNA are first encoded into mRNA in a process known as transcription. Transcription happens in the nucleus and involves an initial step of unwinding or unzipping of the double helix DNA.
Thereafter, the mRNA produced during transcription is transported from the nucleus to the cytoplasm where it gets attached to the ribosome.
In conjunction with the rRNA and the tRNA, the codons in the mRNA becomes translated into their respective amino acids. The amino acids are then linked by a polypeptide bond leading to the production of protein.
Hence, the correct sequence of event is:
<em>The DNA double helix unzips.</em>
<em>A strand of RNA is made from a strand of DNA.</em>
<em>The strand of RNA leaves the nucleus.</em>
<em>The strand of RNA moves to the ribosome.</em>
<em>A protein is produced.</em>
Independent ( because the reading relies on the different cuffs ) making this a reliable yet invalid experiment. It’s reliable because it consistently differed by 15 points each different cuff. Invalid because the readings were constant with the correct cuff, putting the incorrect cuff size can cause inaccurate readings
The condition of the AIDS (Acquired Immunodeficiency
Syndrome) is caused by a virus called HIV (Human Immunodeficiency Virus). The
virus itself attacking the definite type of immune system cell inside the body.
Its cell also known as the helper cells or CD4 helper lymphocyte cells particularly
in the adaptive immune system. HIV ruining these cells, it’ll make so hard for
the body to combat off and guard off other infectious diseases. When people
gets HIV, even slight infection like fever or colds can be much critical
because the body itself has difficulty healing. Hence, immune system of one’s
person will be lowered because the helper cells are slowly being destroyed and it
makes the person unsafe.
