The development of electron microscopes has further opened our window on the cell and its organelles. What is considered a major

disadvantage of the electron microscopes?
Biology

ludmilkaskok [199]4 years ago

Answer;

-Electron microscopes can not view live cells because the method of preparation is lethal.

Explanation;

-The electron microscope is a type of microscope that uses a beam of electrons to create an image of the specimen. It is capable of much higher magnifications and has a greater resolving power than a light microscope, allowing it to see much smaller objects in finer detail.

-There are many different disadvantages to using a electron microscope for example they are extremely expensive which limits the availability to use them. Furthermore researchers are unable to observe the image in color, as electrons do not possess color, which may not allow the image to be understood easily.

-Additionally the use of the electron microscopes require a large space for example a whole room which may not be feasible.

In compost heaps, dead plants are broken down into microbes. This breakdown is much Slower when the weather is cold, the weather
gavmur [86]

Decomposers are important because they develop the mineral salts and other substances that form living beings in the soil or water. These substances can be reused by other living beings.

<h3>A) what are the three conditions inside compost piles necessary for microbes to function quickly?</h3>

temperature, humidity and nutrient disposition

<h3>B) why is the decomposition of dead plants important for living plants?</h3>

Decomposers feed on the remains of living beings, such as plants and animals, and release mineral salts and other nutrients into nature. These nutrients are then used by producing organisms, such as plants, and are therefore reused.

With this information, we can conclude that Decomposers play a critical role in the flow of energy through an ecosystem. They break apart dead organisms into simpler inorganic materials.

starting with a fertilized egg (zygote), a series of six cell divisions would produce an early embryo with how many cells?
maxonik [38]

Starting with a fertilized egg (zygote), a series of six cell divisions would produce an early embryo with 64 cells.

<h3>What about zygote?</h3>
  • A zygote is a eukaryotic cell created when two gametes fertilize one another.
  • The genome of the zygote, which is made up of the DNA from each gamete, has all of the genetic material for a brand-new unique organism.
  • The zygote represents the earliest developmental stage of multicellular organisms.
  • Zygote, the fertilized egg cell produced when a female gamete (egg, or ovum) and a male gamete combine (sperm).
  • The zygote stage is brief in the embryonic development of humans and other animals, and it is followed by cleavage, in which the single cell divides into several cells.
  • When male and female gametes combine to produce an embryo, the first diploid cell that results is known as a zygote.
  • The first week after conception is when the zygote stage develops.
  • Zygote is the name given to the sperm and egg together.
  • All of the DNA required to develop into a baby is present in the zygote.
  • The mother's egg and the father's sperm each contribute 50 percent of the DNA.
  • The following several days are spent by the zygote moving down the fallopian tube.

If a person with AB blood (genotype IAIB) produced an offspring with a person who’s IAi, what’s the chance that the offspring wi
antiseptic1488 [7]

Answer:

50% of getting A blood type

Explanation:

Using a punnet square you have (sorry cant do a square)

 <u>   IA            IB</u>

<u />

<u>IA</u>

<u />

<u />

<u>i</u>

<u />

Then you you add all the possible combinations from both parents genes

              IA               IB

IA          IA IA           IA IB

i            IA i               IB i

You now have a 50% chance of A type blood because the lowercase (i) wont change the blood type outcome because the IA over shines it.
