Answer:
Your body will always try to keep you at the same temperature, for example, even when it's raining. Asthma is a good example of homeostasis gone wrong and the body acts out of proportion to a stimulus starting a process that leads to symptoms.
Plant cells have a cell wall, but animals cells do not. Cell walls provide support and give shape to plants. Plant cells have chloroplasts, but animal cells do not. ... Plant cells usually have one or more large vacuole(s), while animal cells have smaller vacuoles, if any are present.
Answer:
Parasympathetic nervous system
Explanation:
Parasympathetic nervous system (PNS) along with sympathetic nervous system (SNS) makes autonomic nervous system (ANS). ANS controls the functioning of internal processes like digestion rate, heart rate, respiratory rate etc. During a threat or stressful situation SNS is activated. It increases heart rate, respiratory rate and directs blood flow towards peripheral muscles as a part of "fight or flight response". When the situation becomes normal, PNS is activated which restores all the vitals as a part of "rest and digest" mechanism.
Since here Byron almost got into an accident, he was scared a lot due to which his SNS was activated. Eventually when he realized that he is out of danger, his PNS got activated which returned his heart rate and blood pressure to normal levels.
Answer:
Ecosystem engineers are species that modify their environment in a significant manner, creating new habitats or modifying existing ones to suit their needs.
Answer:
The correct answer would be -A pre-mRNA becomes mRNA by cutting out different introns
Explanation:
During the process of the RNA splicing, pre-mRNA has several specific segments of sequence that are identified by the spliceosome and then removed from the pre-mRNA. Specific parts that are removed are known as introns and the parts that stuck to become mRNA are exons.
Gene sequences in the eukaryotic genome can code for more than one protein due to removing the different introns every time to become mRNA from pre mRNA.
