The correct answer is: A) pontine respiratory centers
The respiratory centre in the pons is responsible for generating and maintaining the rhythm of respiration. Besides this elementary function, it also has the ability to adjust respiration rhythm in c response to physiological changes. Respiratory centre consists of three major respiratory groups of neurons:
• The dorsal respiratory group (DRG)- initiates inspiration (inhalation)
• the ventral respiratory group (VRG)-responsible for exhalation
• Pontine respiratory group- includes the pneumotaxic (controls both the rate and the pattern of breathing) and apneustic centers (promotes inhalation by sending signals to dorsal group).
Answer:
A) Formulate question,conduct research,propose hypothesis,test hypothesis
Explanation:
The scientific method is pertinent to the success of a scientific experiment. The scientific method is a sequential steps of processes involved in an experimentation. The correct order of steps that determines the process when following the scientific method are:
1) Formulate question: Asking a question about what has been previously observed is the key to starting a scientific method.
2) Conduct research: Research is done based on a previous observation that has been made by in order to gather necessary information.
3) Propose hypothesis: A hypothesis is a predictive statement or explanation to an asked question about the experiment that can be tested. It usually goes in an IF, THEN format.
4) Test hypothesis: As stated in the previous step, a hypothesis must be testable, which is done by conducting an experiment. The outcome of the experiment proves or disproves the hypothesis.
Answer with Explanation:
Coriolis Force - refers to the fictitious force that acts perpendicularly to the direction of a rotating motion.
Air parcel - refers to a body of air that is <em>"imaginary."</em>
Pressure gradient - the change in pressure across a given distance.
Pressure gradient force - the net force that is being directed from high pressure to low pressure.
When an<em> air parcel is at rest, </em><u>the pressure gradient force acts upon it.</u> It will then move from<em> high pressure to low pressure.</em>
However, when the air parcel starts to be in motion, its direction will be changed with the help of the Coriolis force. Thus, it moves to the right side of the Northern hemisphere.
Once the speed of the wind increases, the change in direction of the air parcel increases. This happens until the pressure gradient force and the Coriolis Force are equal in magnitude. When this happens, the wind will start blowing parallel to the points of equal pressure. The wind will now then be referred to as in "geostrophic balance."
When friction happens, the geostrophic balance breaks. The flow of the wind will be slowed down. This means that the Coriolis force will also be lessened. The air parcel will then move towards the lower region.
Answer:
. 2C- acetyl Co-A from the link reaction enters the kreb Cycle to combine with 4 Carbon Oxaloacetate to form 6- Citrate
The Citrate forms intermediate Isocitrate, which eventually formed 6-C alpha ketoglutarate.
The alpha-ketoglutarate forms the intermediate succinyl-Co A, which later formed 5C-succinate.
5C -Succinate forms 4C-fumarate, the latter formed 4C-malate- which eventually formed 4C-oxaloacetate.
The 4C of these compounds is fixed, to ensure constant availability of 4C of oxaloacatate for 2C Acetyl -CoA to bind it for the cycle to continuously occur for production of first product Citric Acid from which other products are formed from.
Explanation:
Botana curus is a plant that produces curus which is a substance that is used to cure different kind of cancer.
This is an endangered species that cannot be grown in the laboratory. The ability to produce curus in the laboratory is not feasible.
The human activities that could have endangered botana curus is:
Pollution: It lead to slow down the rate of growth of the plant.
Overexploitation: The over use of plant for its medicinal purpose.
Habitat: The natural habitat of the plant has been changed due to various human activities.
