Answer:
a. What is the significance of the rainfall? These bacteria resist desiccation, and its dispersion is favored by winds. A decrease in rainfall means a dryer environment, which the bacteria can resist and makes it easier for the cell to be carried somewhere else by winds.
b. The etiologic agent of the disease is Coxiella burnetii
c. This is an example of a zoonosis
Explanation:
Q fiber Pneumonia is a zoonosis world-widely distributed and of global importance, which etiologic agent is Coxiella bunetti.
Zoonosis: Referred to as the infectious diseases that are naturally transmitted from animals to human beings. Among zoonotic pathogens, there are bacteria, viruses, or parasites. They propagate by direct contact, water, and wind, among others. These diseases represent a global importance problem due to the close ties with animals. Zoonotic diseases increase even more as human being keeps dispersing and invading natural wild environments to raise cattle and farm, among other activities. The etiologic agent is the element that propitiates the origin and evolution of a disease. Many bacteria and viruses might be considered to be one of the most common etiological agents.Populations in contact with goats, sheep, and cattle, use to have a positive result for antibodies against Coxiella burnetii. This bacteria is transmitted to humans orally and by inhalation. The microorganisms resist extreme conditions and are highly infectious. The inhalation of only one cell can produce an important infection in the host. It resists desiccation and any other environmental degradation. They can persist for several months and be transported by winds to farther places. This makes it even more difficult to determine the epidemiologic origin.
Using the Gizmo, determine how coal and petroleum (oil) are formed. Describe the steps required to form each fuel from atmospheric CO2.
Answer and Explanation:
Petroleum and coal are fossil fuels. The degradation of the earliest plants forms them. These dead plants started to pile up and form peat. Then the pressure and heat from various geological procedures convert peat into coal. Coal is a combustible rock which contains 50% carbon. Anthracite, Lignite and bituminous are the types of coal, and the formation of coal depends upon the quantity of hydrogen, oxygen and carbon. Petroleum exists naturally in liquid form and formed by decomposed organic matter. Fossil fuels can be refined into usable substances. Gasoline, tar, lubricants and many other products are obtained from petroleum. There are two steps, which required to form fuel from atmospheric carbon dioxide. In first step carbon dioxide is converted into carbon monoxide. In the second step, carbon monoxide combines with hydrogen to form hydrocarbon fuels. The formation of fuel is a natural process when animals respire carbon dioxide release in the atmosphere.

Answer:
1. Receptor (nociceptor).
2. Afferent neurons.
3. Spinal cord.
4. Motor neurons.
5. Efferent neuron (effector).
Explanation:
In Biology, stimulus can be defined as an obvious change in either the chemical or physical structure of an organism' environment (either external or internal). Thus, all living organisms (both animals and plants) respond to changes in their environment and consequently, an appropriate response or reaction is made. Also, stimulus arising from within the organism is known as internal stimulus while those from its environment are known as the external stimulus.
In organisms, the specialized cells that detect stimulus are generally known as sensory receptors while a group of these receptors is referred to as sense organ.
In this scenario, you accidentally stub your toe on a chair when walking in a darkened room. A receptor (nociceptor) relays this information by sensory nerves in the afferent neurons to the spinal cord, which in this case is the spinal cord. You immediately step back because the spinal cord sends a command via the motor neurons to your leg muscles, which are acting as the efferent neuron (effector).

Explanation:
The glucose transporter used by cells to obtain glucose from the media is a protein embedded in the membrane. When researchers first started to investigate the glucose transporter's structure they had trouble because it seemed to have 2 differnet shapes! Eventually they realized that the glucose transporter changes shape as it moves glucose into the cell but does not require energy to do it's work. Which of the following is the best description for the glucose transporter?
a. It's a carrier protein doing facillitated diffusion
b. It's a carrier protein doing active transport
c. It's a protein channel doing facillitated diffusion
d. It's a protein channel doing active transport
Answer:
a. It's a carrier protein doing facillitated diffusion
Explanation:
Facilitated diffusion may be defined as the transportation of molecules from a high concentration to a low concentration that is down the concentration gradient without input of the energy. Whereas the active transport is transportation of the molecules from the low concentration to the high concentration which is against concentration gradient by the membrane protein.
The glucose transportation process requires membrane protein for the transport and does not require any energy. Therefore, it is carrier protein which is doing the facilitated diffusion.

Explanation:
Using the Gizmo, create four energy paths to explain how the toaster could get its energy.
Answer and Explanation:
Energy is well-defined as the capacity to do work. Heat is the kind of energy. It is transmitted from the high-temperature object to the low-temperature object. When electricity runs over a wire, energy is transferred from one end of the wire towards another end. Electricity flow in the wire by electrons. When electricity flows, the electrons collide with one another and give off heat due to collision. Less collision of electrons produce less heat, and more collision of electrons produce more heat. When the toaster wire plugged into the electricity supply, electric energy began to flow through the wire—the electric current run over a series of filaments. The filaments are thin and connected. When electric energy flows through the filaments, they glow red hot and transfer the bread. The filaments are present on both sides of the toaster. So the bread cook from both sides at a similar time.

Which is a difference between active and passive transport?
A. Eukaryotes are capable of active transport, while prokaryotes are capable of passive transport.
B. Cells only carry out active transport when they need to move, while passive transport occurs constantly.
C. Active transport requires ATP, while passive transport does not.
D. Cells with mitochondria carry out active transport, while cells without mitochondria carry out passive transport.
The difference between active and passive transports is that active transport requires ATP while passive transport does not. the correct option would be C.
Active transports are the movement of materials in and out of the cell that requires the expedition of energy. The energy is usually in the form of Adenosine Triphosphate (ATP).
Active transport is unlike passive transport because the latter requires no energy. In other words, passive transports are spontaneous.
Active transport usually involves the movement of materials against their concentration gradients while passive transport is the complete opposite.
Examples of active transport include the sodium-potassium pump, movement of amino acids in the intestinal tracts of man, etc while examples of passive transport include simple diffusion of oxygen to the alveolar walls in the lung.

Answer:
Mitochondria and chloroplasts have their own DNA
Mitochondria and chloroplasts are surrounded by two membranes
Mitochondria are about the same size as most bacteria
Explanation:
The endosymbiotic theory, also known as symbiogenesis, is a theory that explains how eukaryotic organisms have been formed from prokaryotic cells. This theory holds that eukaryotic organisms originated from prokaryotic organisms that engulfed another prokaryotic cell, creating thus an organism with multiple membranes. In consequence, eukaryotic organelles, including mitochondria and chloroplasts, would have evolved from these prokaryotic endosymbionts. Moreover, both mitochondria and chloroplasts contain their own genes which are localized in a circular chromosome, thereby supporting an endosymbiotic origin of both organelles. Finally, bacterial cells have 1 to 10 microns in length, while mitochondria have a similar size, thereby also supporting an endosymbiotic origin of this organelle.

A study is being done to test the effects of temperature on the number of microbial colonies. Four different incubators are set up, each at a different temperature with one culture plate in each. Each plate has the same nutrient content, pH, and are inoculated with microorganism samples from the same source. At the end of the experiment, the number of colonies on each plate is counted. What is the independent variable
Answer:
The correct answer is - the different temperatures of incubators.
Explanation:
An independent variable is a variable in a study or research which is manipulated or changed to check or find the effect on the dependent variable. The independent variable is the only factor that changes in research while other factors remain constant that can affect the result in the study.
In this case or study, there is the only factor that is manipulated is the temperature of incubators is manipulated to see the effect of temperature on the number of microbial colonies. Thus, the different temperatures of incubators is the independent variable here.

Which is the classification of any naturally occurring solid inorganic substance characterized by a crystal structure? A. fossil B. metal C. mineral D. rock
Answer:
C. mineral
Explanation:
In science, matter can be defined as anything that has mass and occupies space. Any physical object that is found on earth is typically composed of matter. Matter are known to be made up of atoms and as a result has the property of existing in states. The three (3) classical states of matter are;
1. Liquid: is the state of matter in which the physical substance can be poured and takes the shape of its container. Also, liquids generally have a definite volume. Examples of liquids are urine, water, milk, blood etc.
2. Gas: is the state of matter in which the physical substance has no definite shape or volume and as a result fills all available space. Also, gases are easily compressible, takes the shape of its container and can flow. Examples of gases are hydrogen, oxygen, argon, nitrogen etc.
3. Solid: is the state of matter in which the physical substance has a definite shape and fixed volume but not compressible. Examples of solids are pen, screwdriver, television, car etc.
Mineral is the classification of any naturally occurring solid inorganic substance characterized by a crystal structure. Also, minerals are homogeneous in nature with a defined chemical composition and characterized by a crystal structure comprising of ions, atoms, or molecules in an orderly arrangement.
Some examples of minerals are iron, copper, aluminum, tin, coal, quartz, feldspar, mica, etc.
How many factors does a scientist want to differ between the experimental and control groups?
A) 2
B) 0
C) 1
D) 3
Answer:
C
Explanation:
The experimental and control group differ by only one factor for a scientist, and that is the independent variable.
A scientist will always try to isolate the effects that are due to a variable and keep every other variable constant. The variable that is manipulated in order to measure its effect is known as the independent variable. A control group usually forms the basis for measuring the effects of the independent variable. While the independent variable is varied in experimental groups, it kept at the zero level for the control group.
The correct option is, therefore, C.
