What is the Ecological Effect of the Vaccine?
There are advantages and disadvantages to both types of microscopes. Compare and contrast the two types outlined
here. What evidence supports a DISADVANTAGE of the transmission electron microscope?
A)
The beam of electrons used in the transmission electron microscope often
damage the delicate specimens being observed.
B)
C)
The transmission electron microscope magnifies specimens to a much
higher degree than an optical microscope and therefore requires a very
thin specimen.
The transmission electron microscope requires that specimens be put
inside a vacuum chamber so the microscope cannot be used to observe
living specimens.
The typical electron microscope can zoom in at only a few discrete levels
and often specimens are best observed at intervals not reached with this
microscope.
D)
Answer: C
Explanation: I just did it on usa test perp
The transmission electron microscope requires that specimens be put inside a vacuum chamber so the microscope cannot be used to observe living specimens. The correct option is C.
What is electron microscope?The technique of electron microscopy (EM) is used to obtain high-resolution images of biological and non-biological specimens.
In biomedical research, it is used to investigate the detailed structure of tissues, cells, organelles, and macromolecular complexes.
An electron microscope can only be used in a high vacuum. This makes using a microscope to study living organisms impossible because they would evaporate and disintegrate under such conditions.
Transmission electron microscopy is a microscopy technique in which an image is formed by passing an electron beam through a specimen. The specimen is usually an ultrathin section less than 100 nm thick or a grid suspension.
Because the transmission electron microscope requires specimens to be placed inside a vacuum chamber, it cannot be used to observe living specimens.
Thus, the correct option is C.

Passive membrane transport processes include ________. movement of a substance down its concentration gradient movement of water from an area of low concentration to an area of high concentration consumption of ATP the use of transport proteins when moving substances from areas of low to high concentration
Answer:
movement of a substance down its concentration gradient
Explanation:
As you may already know, the plasma membrane of a cell has a semi-impermeable nature. This means that the plasma membrane allows only a few very specific substances to pass in and out of the cell. This movement of subtlety can happen in a passive or active way. In an active way, the moment is made through proteins of the membranes. Passively, the movement is made through a concentration gradient, where the substance is able to pass from the more concentrated side to the less concentrated side.
Identify the organelle that packages and secretes proteins and membrane parts
A. Nucleus
B. Mitochondria
C. Golgi Apparatus
D. Cell Membrane
what impact are these practices expected to have on soil pH and why?
Inherent factors that affect soil pH include climate, mineral content, and soil texture. Natural soil pH reflects the combined effects of the soil-forming factors (parent material, time, relief or topography, climate, and organisms). The pH of newly formed soils is determined by the minerals in the parent material.

Explain how the central nervous system and the peripheral system work together to keep the body activities in balance.
Answer:
Voluntary motions in the skin, bones, joints, and skeletal muscles are controlled by the somatic nervous system. Both of these PNS systems collaborate with the CNS to control physiological functions and offer responses to external stimuli.
Explanation:
The central nervous system and peripheral nervous system work together as the nerves of PNS comes out from CNS and the peripheral nervous system guide the brain and spinal cord to receive signals from the body to work.
What is the nervous system?The nervous system is divided into two parts, the central nervous system, and the peripheral nervous system. The central nervous system consists of the brain and spinal cord. The peripheral nervous system contains all the nerves which came out from the brain and spinal cord.
Both systems work together as the nerves of the PNS connected with the brain and spinal cord. The nerves signal the brain and brain when giving signals, they travel through the nerves to the body.
Thus, together, the central nervous system and peripheral nervous system control how the brain and spinal cord receive signals from the body to function. The central nervous system sends PNS nerves out from the spinal cord.

Which of the following processes depend on fusion?
A. the atomic bombs used in World War II
B. the energy production in the sun
C. the geothermal heating in the mantle of the Earth
D. the energy production in nuclear reactors
Answer:
B. the energy production in the sun.
Explanation:
The sun ngenerates its energy by nuclear fusion of hydrogen nuclei into helium.
The right answer to the provided question is that the sun's energy generation method is based on fusion.
How nuclear fusion occurs in sun?
Nuclear fusion is the process that occurs when two or more atomic nuclei unite to generate one or more distinct atomic nuclei and subatomic particles neutrons or protons.
The mass differential between reactants and products results in either energy release or absorption.
In the Sun's core, hydrogen is being converted into helium. This is referred to as nuclear fusion.
The fusion of four hydrogen atoms produces one helium atom. During the process, some of the mass is converted into energy.
So, we can conclude that Nuclear fusion occurs within the sun's core. Because of the amount of pressure within the sun, nuclear fusion occurs at its core.

In addition to the transmission electron microscope (TEM), there is another type of electron microscope that is frequently used for specific purposes when studying cells and tissues, and even whole organisms. This microscope is called a scanning electron microscope (SEM). Use your lab manual, its support resources, and/or the Internet to investigate the use of scanning electron microscopy for biological applications. After gathering this information, please answer the following question. When would it be appropriate to use the SEM rather than the TEM
Answer:
The basic difference between SEM and TEM is that TEM generates an image with the assistance of radiation that goes through the specimen, while the images generated by the SEM take place with the assistance of electrons getting released from the surface of the specimen.
SEM is primarily used to examine the composition of the surface, with the help of SEM one can study the microbes present in the ecological niche like in the lining of the gut and human skin. Due to its great depth, it is considered the electron microscope analog of a stereo light microscope. It helps in providing complete images of the cells present on the surface, which are not easy to get with the help of TEM. Due to its enhanced functionality, it can also be used for size determination and particle counting, and also for process control.

in the fermentation experiment using yeast with the different sugars what was the dependent variable
Answer:
The dependent variable is fermentation rate.
Explanation:
When finding dependent variable phrase it like this:
______ depends on _____.
Where the first blank is the dependent variable and the second blank is the independent variable. For example, if I were to test the effects of pH on an enzyme, I would say the function of the enzyme depends on the pH level. This makes the function of the enzyme the dependent variable. In this case, fermentation rate depends on the different sugars. Hope this helps!
