7. To test a new voice feature in a cockpit design a flight simulator was used. The simulator was programmed to
give visual readings of flight information, or to give visual and auditory (voice) readings of flight information. All
test pilots were put through a simulated emergency landing procedure, but were randomly assigned to the
visual, or visual and auditory conditions. Flight experts rated each pilot's performance in the simulator on a
scale of 1 (very poor) to 10 (excellent).

Answers

Answer 1

The variables in the simulation procedure carried out are :

Independent variable = Simulator Independent variable = Simulator Dependent variable = Performance

The dependent and independent variables are critical in any experimental study as both variables encompasses the variable to be measured and the variables manipulated in other to obtain the variable to be measured.

Independent variable : This is also called the predictor variable which is tweaked in other to obtain changes in the measured or dependent variable. In the experiment performed, the simulator is the independent variable has it has different visual or visual and auditory conditions capable of causing changes to the performance rating.

The dependent variable is the variable being measured in an experiment. In this case, it is PERFORMANCE. It is the measured output obtained as the the pilot are being rated based on the simulation.

Imagine taking a bite of a pizza. Briefly discuss the role that each part of the brain takes in this simple act. Medulla, Pons, Cerebellum, Thalamus, Hypothalamus, Amygdala, Hippocampus, Parietal Lobe, Occipital Lobe, Temporal Lobe, Frontal Lobe.

Answers

Answer:

- Medulla: transmits signals between the spinal cord and higher brain levels

- Pons: transmits impulses related to the voluntary skeletal movements from the cerebrum to the cerebellum

- Cerebellum: coordinates skeletal muscle contraction, conscious/subconscious movements, maintains muscle posture, and balance

- Thalamus: regulation of the human nervous system

- Hypothalamus: maintains the overall homeostasis of the body

- Amygdala: processes fearful and threatening stimuli  

- Hippocampus: regulates learning, memory encoding and consolidation, and spatial navigation

- Parietal Lobe: processes information from the outside world (e.g., touch, taste, temperature)

- Occipital Lobe: interprets information from the eyes

- Temporal Lobes:  process sensory information (i.e., pain and auditory stimuli)

- Frontal Lobe:  higher cognitive functions (e.g., memory, problem-solving, emotions, impulse control, etc)

Explanation:

The medulla (medulla oblongata) is the lowest portion of the brainstem, which is linked by the pons to the midbrain and continues with the spinal cord. The medulla is known to transmit signals between the spinal cord and higher brain levels, thereby controlling autonomic activities (e.g., heartbeat and respiration). The pons is a mass of transverse nerve fibers that links the medulla with the cerebellum, it transmits signals from the forebrain to the cerebellum. The pons is involved in different functions, e.g., sleep, respiration, hearing, equilibrium, taste, eye movement, swallowing, bladder regulation, facial expression, etc. The cerebellum is a small part of the brain involved in physical movements (e.g., posture, balance, coordination), which receives sensory information from sensory systems, the spinal cord, and different parts of the brain. The cerebrum is the largest part of the brain, it is involved in speech, thinking, reasoning, problem-solving, emotions, initiating/coordinating movements, regulating temperature, learning, etc. The thalamus is a mass of gray matter located in the forebrain which is involved in diverse functions (i.e., relay of sensory signals, regulation of consciousness, sleep, alertness, etc). The hypothalamus is a small, central, area of the brain that connects the nervous to the endocrine system that acts to maintain the overall homeostasis of the body. The amygdala is a structure located in each hemisphere of the brain that processes fearful and threatening stimuli. The hippocampus is a structure located in the depths of the temporal lobe that regulates learning, memory encoding and consolidation, and spatial navigation. The parietal lobe is located at the upper back area in the skull, it is involved in processing sensory information from the surrounding world (e.g., touch, taste, temperature). The occipital lobes are responsible for transmitting visual information to the temporal lobes, and they are also associated with memory skills. The frontal lobe is the most anterior part of the brain, which is involved in higher cognitive functions (e.g., social interaction, motor function, memory, emotions, impulse control, problem-solving, etc).

Chemosynthesis _______. Question 11 options: uses energy derived from hydrocarbons and hydrogen sulfide in place of solar energy produces carbohydrates and sugars occurs around hydrothermal vents near the oceanic ridge system Both a and c are correct. All of the above are correct.

Answers

Answer:

The answer is all of the above are correct.

Explanation:

Chemosynthesis occurs in bacteria and other organisms and involves the use of energy released by inorganic chemical reactions to produce food. All chemosynthetic organisms use energy released by chemical reactions to make a sugar, but different species use different pathways. For example, at hydrothermal vents, bacteria oxidize hydrogen sulfide and add carbon dioxide and oxygen to produce sugar, sulfur, and water:  

CO2 + 4H2S + O2 ⇒ CH20 + 4S + 3H2O.

Chemosynthesis is the process by which food (glucose) is made by bacteria using chemicals as the energy source, rather than sunlight. Chemosynthesis occurs around hydrothermal vents and methane seeps in the deep sea where sunlight is absent. During chemosynthesis, bacteria living on the seafloor or within animals use energy stored in the chemical bonds of hydrogen sulfide and methane to make glucose from water and carbon dioxide (dissolved in seawater). Pure sulfur and sulfur compounds are produced as by-products.

what are the cells that pass from parents to their children

Answers

Answer:

Genes are the blueprint for our bodies. If a gene contains a change, it disrupts the gene message. Changes in genes can cause a wide range of conditions. Sometimes a changed gene is inherited, which means it is passed on from parent to child. Changes in genes can also occur spontaneously.

8. Substitution mutation

9. Frameshift mutation

Explanation:

A substitution mutation is any kind of mutation that involves replacement of one or more nucleotide base by another in a sequence.

A frameshift mutation, on the other hand, is a mutation that changes the reading frame of the sequence. Two types of mutations cause frameshift viz: insertion and deletion mutation.

In the following sequences, mutation has occured as follows:

7. UGU-CCG-GAA-CGA to UGC-CGG-GAA-CGA - Substitution mutation has occured because nucleotides C and G has replaced C and U in the first and second codons respectively.

8. GAA-CGU-AGC-GGU to GAU-CGU-AGC-GGU- A substitution mutation because nucleotide U has replaced A in the first codon.

9. UGU-UUC-CCU-UAA to UGU-UCC-CUU-AA - A frameshift mutation because nucleotide U has been removed from the second codon, hence, causing a change in the reading frame.

Cell specialization is important during the growth and development of
a multicellular organism. This process is most directly regulated by

Answers

Answer:

Protein

Explanation:

A cell can be defined as the fundamental or basic functional, structural and smallest unit of life for all living organisms.

Cell specialization is also referred to as cell differentiation and it can be defined as a biological process through which generic cells transform into specific cell types, so as to enable them perform certain functions within the body of a living organism.

Simply stated, it's the special function or job in the body of a living organism that are associated with cells.

Generally, cell specialization plays a significant role in the development of embryos.

Some living organisms are unicellular while others are multicellular in nature.

A unicellular organism refers to a living organism that possess a single-cell while a multicellular organism has many (multiple) cells.

Cell specialization is fundamental and key for the growth and development of a multicellular organism.

Furthermore, cell specialization as a process is most directly regulated by protein; one super regulating protein encourages cell differentiation while the other tries to stop or prevent the process. These proteins are referred to as master regulating proteins or Helix-Loop-Helix proteins.
