1.What is unique about the reflex behavior?
The messages never reach the central nervous system
It originates in the spinal cord, not the brain
It is localized in the cerebellum instead of the cortex
It only uses the autonomic nervous system
2.The peripheral nervous system is made up of:
The sympathetic and parasympathetic systems
The autonomic and somatic systems
The environment and sensory receptors
The brain and spinal cord
3.Which of the following behavior would be associated with the SOMATIC nervous system?
Breathing during sleep
Heartbeat
Scratching an itch on your head
Sweating
4.In regards to the Autonomic nervous system, Sympathetic is to Parasympathetic as:
Automatic Behaviors: Voluntary Behaviors
Calms you down; Reacts to threat
Voluntary Behaviors
Reacts to a threat; Calms you down
5.Sensory nerves that carry information from the environment and bring it back to the the Central Nervous System are part of the
Sympathetic Nervous System
Parasympathetic Nervous System
Somatic Nervous System
Autonomic Nervous System
Answer:
The thing that is unique about the reflex of behavior is it is involuntary and almost instantaneous reaction to a stimulus. Take plants for an example. Their stimuluses are tropisms. Phototropism is a reaction to a light source in order to achieve photosynthesis. Hydrotropism is a plant's reaction to a nearby water source, in which the plant's roots grow towards it. Geotropism is a plant's reaction to gravity, in which the plant's roots grow down, and the stem grows up.
The peripheral nervous system is made up of The brain and spinal cord.
The behavior that would be associated with the SOMATIC nervous system is scratching an itch on your head.
In regards to the autonomic nervous system, sympathetic is to parasympathetic as calms you down; reacts to threat.
Sensory nerves that carry information from the environment and bring it back to the central nervous system are part of the autonomic nervous system.

What are the sex chromosomes? Explain how it is shown in male and female; and karyotyping
Answer:
Females have two X chromosomes, while males have one X and one Y chromosome. A picture of all 46 chromosomes in their pairs is called a karyotype. A normal female karyotype is written 46, XX, and a normal male karyotype is written 46, XY.
Explanation:
Sex chromosomes are chromosomes which are responsible for sex determination. These are the X and Y chromosomes. Females have two X chromosomes and males have one X and one Y chromosome in their sex cells/gametes. Karyotyping is the visualization of chromosomes after blocking the cells in mitosis and staining; this allows us to identify the size, shape, and number of chromosomes present in cells, which is significant because extra, missing, or abnormal chromosomes can cause developmental problems or issues with body functions.

Explain why oxygen and carbon dioxide diffuse in opposite directions in the lungs?
Answer:
There is a higher oxygen content in the air of the lungs than that of oxygen-depleted blood and a lower carbon dioxide concentration. This gradient of concentration causes gas exchange during respiration.

Below is the base sequence on one side of a DNA molecule. What would the complimentary side of this strand of DNA read? ATC TCA GAT CGT CAG
UAG AGA GUA CGA GUC
AUC UCA GAU CGU CAG
ATC TCA GAT CGT CAG
TAG AGT CTA GCA GTC
The complimentary side of this strand of DNA would read: TAG AGT CTA GCA GTC.
What is complementary strand?The complementary strand is a term used to describe the second strand of DNA in a double-stranded DNA molecule. The two strands of DNA run in opposite directions and are held together by hydrogen bonds between complementary base pairs, which are adenine (A) and thymine (T), and cytosine (C) and guanine (G).
The complementary nature of the two DNA strands allows for accurate duplication of genetic information when the cell divides. In addition, the complementary strand can serve as a template for the production of messenger RNA (mRNA), which is used to direct the synthesis of proteins. The complementary strand is therefore an essential component of DNA structure and function.

In a parallel circuit, there is only one path for current to take. Please select the best answer from the choices provided T F
Answer:
False.
Explanation:
A parallel circuit has more than one path for current flow. The number of current paths is determined by the number of load resistors connected in parallel. Total current in a parallel circuit is the sum of the individual branch currents.
Which type of cell has free-flowing DNA? O Fungi O Prokaryotic O Eukaryotic O Protist
Answer: Prokaryotic cells have free flowing DNA. This DNA is in a circular shape and flows freely in the cytoplasm
Answer:Prokaryotic cells
Explanation:
Prokaryotic cells as well as bacteria have a free-floating chromosome that is normally circular and is not enclosed in a nuclear membrane instead The DNA simply lives in a region of the cell called a nucleoid.Prokaryotic cells only have a small range of organelles, normally only a plasma membrane and ribosomes
What is a Prokaryotic cell?
Prokaryotic cells comprise bacteria and archaea. They Normally have a diameter of 0.1–5 μm, and their DNA is not contained within a nucleus. alternatively , their DNA is circular and can be located in a region called the nucleoid, which floats in the cytoplasm

During fermentation, how do changes to a molecule of pyruvic acid to lactic acid or ethyl alchol contribute to
the formation of ATP?
Answer:
Some organisms, such as some bacteria, will undergo lactate fermentation. Two pyruvates are converted to two lactic acid molecules, which ionize to form lactate. In this process two NADH + H+ are converted to two NAD+. Our muscle cells can undergo this process when they are in oxygen debt.

What materials do motor neurons need to survive and how do they get those materials?
Answer:
Neurons are made up of three major parts: a cell body, or soma, which contains the nucleus of the cell and keeps the cell alive; a branching tree like fiber known as the dendrite, which collects information from other cells and sends the information to the soma; and a long, segmented fiber known as the axon, which transmits information away from the cell body toward other neurons or to the muscles and glands.

What is a body function that would contribute to BMR?
Breaking down a burger in the stomach
O Catching a Frisbee
O Heart beating
O Wrestling a Grizzly Bear
Answer:
Breaking down a burger in the stomach.
Explanation:
Basal metabolic rate (BMR) also known as resting metabolic rate (RMR) can be defined as the amount of calories that is required to keep the human body to function properly and perfectly at rest.
This ultimately implies that, basal metabolism is the minimal amount of calories or energy that is required by an individual for maintaining vital functions such as blood circulation, keeping the body warm and respiration while fasting or in a complete mental and physical rest.
Some of the factors that affects the basal metabolism rate (BMR) in humans are height, weight, age, starvation or fasting, thyroxine, fever, stress, malnutrition and growth.
Hence, breaking down a burger in the stomach is a body function that would contribute to BMR.
