Explain a wedge and give 3 examples.

Biology
1 answer:
yKpoI14uk [10]3 years ago
4 0

Answer: A wedge is basically an incline plane. Often portable used for many purposes

Explanation: A wedge is a double inclined plane such that the two sloping surfaces taper to form either a sharp edge or a pointed edge. For example, a knife, an axe etc.

In a few cases, the number of inclined planes used can be more than two as well. In such cases, the sloping surfaces generally taper to form either a very sharp or a pointed edge to split or pierce materials. For example, pins, nails etc.

The front end of a boat is shaped like a wedge so that it can easily cut across the flowing water.

The wedge works on the principle of an inclined plane.

The Door Stop Is an example of one,

A Knife is a very thin wedge because it slices through objects

Chisels are used to dig into stone and chip away at it to create sculptures.

Which of the following will most likely happen to an enzyme if it is placed in
ella [17]

Answer:

The enzyme will no longer bind to the substrate, slowing or stopping the chemical reaction

Explanation:

The enzyme will get denatured and therefore its active site (that binds the substrate) will be deformed and unable to catalyze reactions. The enzymes, mostly made of folded proteins, are made stable by the interactions between the protein’s amino acids side groups. Changes in the pH of the solution influence the charges of these groups hence altering their interactions. This causes the protein enzyme to deform causing it to lose its function.

Triss [41]

Given what we know, two common medical or biological conditions that may create a hazardous environment when working in a microbiology lab are asthma and working with an infectious disease that may become airborne.

<h3>Why would these conditions prove hazardous?</h3>
  • Working with chemicals and microbes can be especially hazardous to individuals with asthma.
  • This is due to the strong effect that certain chemicals can have in triggering an asthma attack.
  • Microbes may also cause upper respiratory tract infections if breathed in, further worsening asthma.
  • Likewise, working with an infectious disease that has the capability to be airborne is especially hazardous given the ease with which one may become infected and transmit the disease.

Therefore, we can confirm that two common medical or biological conditions that may create a hazardous environment when working in a microbiology lab are asthma and working with an infectious disease that may become airborne.

Which observation would provide indirect evidence that supports a hypothesis that the bubbles are o2 ?
zhuklara [117]

Explanation:

D. An increase in bubbles on the plant when it is moved under a brighter light.

The rate of photosynthesis increases with light intensity.

The process of photosynthesis is energy-storing, it converts light energy into chemical energy, which is stored in the bonds of glucose. Thus an increase in light intensity would increase the rate of photosynthesis, and more O2 bubbles would be produced as waste.

Further Explanation:

Photosynthesis is a chemical pathway that’s integral to producing energy in plants and other primary producers. Energy in the form of molecules of glucose is produced from light, water and carbon dioxide while oxygen is released.

Occurring in several complex steps, photosynthesis is a rate limited reaction, depends on several factors including carbon dioxide concentration, ambient temperature and light intensity; the energy is retrieved from photons, I.e. particles of light, and water is used as a reducing agent. Water supplies the chlorophyll in plant cell with replacement electrons for the ones removed from photosystem II.

Additionally, water (H2O) split by light during photolysis into H+ and OH- acts as a source of oxygen along with functioning as a reducing agent; it reduces the molecule NADP to NADPH by providing H+ ionsand produces molecules of the energy storage molecule ATP through an electron transport chain.

This occurs in the thykaloids, where pigment molecules like chlorophyll reside. Later, in dark reactions, NADP and NADPH are used in the Calvin cycle where monosaccharides or sugars like glucose are produced after the modification of several molecules. These store energy in their bonds, which can be released in respiration in the mitochondria.
