Answer:
<em>Many scientists opposed the "cell theory" </em>when it was first introduced because they believed that <u>even "non-living matters" could produce or generate a living tissue.</u> This was called<em> </em><em>"spontaneous generation."</em><em> </em>The appearance of the fly's larva<em> (maggots)</em> on meat supported this belief of theirs.
It was Louis Pasteur who was able to disprove this concept.
Explanation:
The discovery of cell came about when the microscope was invented. It was first discovered by Robert Hooke, an English natural philosopher in the <em>1600s</em>. However, he wasn't really sure about the structure and function of the cell during his time. It was Anton van Leeuwenhoek, a Dutch scientist, who proposed that "<em>motility"</em> is a quality of life.
Developing the cell theory was credited to Theodor Schwann and Matthias Schleiden.
Answer:
protons against a concentration gradient.
Explanation:
Cellular respiration can be defined as a series of metabolic reactions that typically occur in cells so as to produce energy in the form of adenosine triphosphate (ATP). During cellular respiration, high energy intermediates are created that can then be oxidized to make adenosine triphosphate (ATP). Therefore, the intermediary products are produced at the glycolysis and citric acid cycle stage.
<em>Hence, during cellular respiration, most adenosine triphosphate (ATP) is formed as a direct result of the net movement of protons against a concentration gradient in the electron transport chain.</em>
Additionally, mitochondria provides all the energy required in the cell by transforming energy forms through series of chemical reactions; breaking down of glucose into Adenosine Triphosphate (ATP) used for providing energy for cellular activities in the body of living organisms.
Answer:
Bacteria is a type of micro-organism and is also a prokaryote. These organisms can only be seen using a microscope. Some bacterias are harmful while some are helpful for human daily lives, such as probiotics, and are necessary for life. They have simple cell structures as there is no nucleus or membrane-bound organelles. Bacterias can be found in soil, water, plants, animals, etc. They can cause diseases such as Tuberculosis etc. Due to some diseases being caused by bacterias, doctors prescribe Antibiotics which has the ability to stop the activities in bacterial cell that causes it to lose its protective outer covering and completely stops it from multiplying.
Frequency- number of wave cycles that occur in a given amount of time.
Pitch- number of wavelengths in a given amount of time.
Amplitude- fluctuation or displacement of a wave from its mean value. That means how high or low they are away from the center line.
Volume- The perception of loudness from the intensity of a sound wave. The higher the intensity of a sound, the louder it is perceived in our ears, and the higher volume it has.
Wavelength- the distance between the tops of the "waves".
Answer:
Because their structures are different, both are proteins but are shaped in space differently, causing hemoglobin to saturate at high partial pressures of oxygen, and yield oxygen to the medium, while myoglobin at high partial pressures of oxygen will taking.
Explanation:
Hemoglobin has a tetrahedral form, while myoglobin contains a triad form of three main components and not 4.
In addition, myoglobin must capture oxygen to oxygenate the muscle in muscle contraction, since this demands the presence of this gas and the energy currency that is called ATP.
