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.

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.

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:
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.

direction of an object's motion.
Answer:
True
Explanation:
Hope this helps:)
To solve this, we must be knowing each and every concept related to speed, acceleration and its calculation. Therefore, the given statement is false.
What is speed?Speed may be defined as the distance traveled by an item in the amount of time it requires to travel that distance. In other words, it measures how rapidly an item travels but does not provide direction. The term "velocity" refers to the combination of direction and speed.
Acceleration is defined by the rate at which an object's velocity changes with respect to time. When an object's velocity changes, it is referred to as accelerating or to have acceleration. Speed does not include the direction of an object's motion. Acceleration include the direction of an object's motion.
Therefore, the given statement is false.

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.
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.

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).
