A dog starts chasing Gretchen. When her brain sends a signal to her muscles to run, which neurons are at work?sensory
motor
voluntary
involuntary
Answers
Answer: The correct answer is -
motor neurons.
Explanation:
Nervous system ( that includes two branches that are central nervous system and peripheral nervous system) helps in the transfer of nerve impulses to and from the various parts of body.
Sensory neurons receive information from sensory receptors (which are stimulated through outside environment). They take this information to the CNS (central nervous system that includes brain and spinal cord), where it gets processed and interpreted (particularly in the brain).
Ultimately, Motor neurons transfers this interpreted information (from the CNS to the muscles) to the glands, muscles or various other body organs for proper action to take place.
Therefore, motor neurons carry information from the CNS to dog muscles, which alarm him to run away.
Thus, motor neurons are at work.

The nitrogen cycle is a biogeochemical succession process of nitrogen that involves: fixation, ammonification, nitrification, and denitrification. Like any other biogeochemical cycles. This process undergoes and affects the biological, geometrical and chemical aspects in the ecosystem and the abiotic and biotic community. Hence, the nitrogen cycle leads the abiotic component –nitrogen- to contribute to the biotic community, decomposition and primal production. Further, it becomes an essential part of the environment because some life components are contains it, similarly, amino acids, nucleic acids in RNA and DNA.

Answer: Line A is the enzyme, and Line B is the no enzyme
Explanation:
The reaction rate of a chemical reaction is greatly impacted by the presence of an enzyme. Enzymes are biological catalysts that speed up the chemical reaction by lowering the activation energy required for the reaction to occur. Without an enzyme, the reaction rate may be slow or even non-existent, whereas with an enzyme, the reaction rate can be significantly increased.
In order to compare the reaction rate with and without an enzyme, a graph can be plotted with time on the x-axis and the amount of product formed on the y-axis. The reaction without the enzyme would have a slower rate of product formation and would result in a lower slope on the graph. On the other hand, the reaction with the enzyme would have a sharper rate of product formation and would result in a steeper slope on the graph.
It is important to note that the reaction rate with an enzyme can only be increased up to a certain point, as the enzyme can become saturated with substrate molecules. At this point, the reaction rate will plateau and adding more substrate will not increase the rate of product formation.
Understanding the role of enzymes in chemical reactions is crucial in fields such as biochemistry and pharmacology, as many drugs and therapies work by targeting specific enzymes in the body. By manipulating the activity of enzymes, scientists can alter the rates of chemical reactions and ultimately impact physiological processes.

Answer:
The correct answer is: Mucus membrane.
Explanation:
- The lining of the epithelial tissue forming the mucus membrane contains some specialised cells which are called the Goblet cells.
- These cells secrete a slippery substance called the Mucus.
- The Mucus is a dense, aqueous and slippery substance that is composed of anti-microbial enzymes like lysosyme, immunoglobulins (antibodies) and glycoproteins like mucins.
- The mucus secreting cells line the internal tracts of the body that come into contact with outside environment, like the respiratory tract, alimentary canal, urino-genital tract.
- If any microbial pathogen gain access into any of these tracts the lysosyme in the mucus causes the microbial cells to undergo lysis, hence killed.
- The immunoglobulins, on recognising a pathogen, activate the immune cells of the body to fight against the intruding pathogen.

Answer:
Cancer.
Explanation:
Genetically engineered organism (GMOs) may be defined as the organisms whose genetic material has been modified by using the molecular techniques. Animals, plant, bacteria and viruses can be used as GMOs.
The genetically modified hormones in the dairy product is bovine. The bovine hormone helps in increasing the lactation and milk production in cattles. The bovine hormone is responsible for the differentiation and growth of the abnormal cells as well. The process of apoptosis is inhibited by the bovine. This might result in the formation of cancer.
Thus, the correct answer is option (2).
