Answers

Dilution is necessary during pure culture preparation to reduce the bacterial load and allow readable colonies to grow.

Dilution of bacteria culture is carried out in comparison to McCfarlan standard so as to have a decent number of bacteria that will not be too numerous or too little to observe the growth of distinct colonies during culture preparation.

Without dilution, colonies may form but may be too numerous to count. Too much dilution may also lead to no growth in the culture plates.

what solution, (hypertonic, hypotonic, isotonic) would make osmosis go faster?

Answers

Answer:

Explanation:

Osmosis is the movement of WATER molecules across a semipermeable membrane (such as the cell membrane) from where there is a high concentration of water to where there is a low concentration of water. The interior of a living cell consists of cytoplasm, which is a solution of mostly water with dissolved substances such as salt.  

Now for the fun stuff!  An Isotonic solution is a solution that has the same concentration of dissolved substances as is found inside the cell.  If a cell is surrounded by isotonic solution, then there is no net movement of water across the membrane by osmosis, because the concentration of water is the same on both sides of the membrane.

A hypertonic solution is a solution with a higher concentration of dissolved substances than is found inside the cell.  If a cell is surrounded by hypertonic solution, then water will move OUT of the cell by osmosis because there is a higher concentration of water inside the cell compared to outside (where there is lots of dissolved salt, etc.)  A cell in hypertonic solution will shrink.  

A hypotonic solution is a solution with a lower concentration of dissolved substances than is found inside the cell.  If a cell is surrounded by hypotonic solution, then water will move INTO the cell by osmosis because there is a higher concentration of water outside the cell compared to inside.  A cell in hypotonic solution will swell up and, if there is no cell wall, may burst.  A silly but simple way to remember that water moves into a cell in hypotonic solution is that "hypo causes the cell to swell up like a hippo"

how many chromosomes would be found in an allopolyploid plant if its parents had diploid numbers of 2 and 10, respectively?

Answers

Answer:

6

Explanation:

The allopolyploid off spring should have 6 chromosome the gametes produced for the diploid number 2 should be 1 and for 10 it should be 5 (n/2) the two gametesof both parents gametes should then fuse ( 1+5 ) giving us 6

or

gamete chromosomes =n÷2

gametes for diploid number 2

N= 2

2÷2 = I

gamete Chromosome = 1

gamete for diploid number 10

N=10

10÷2 =5

Allopolyploid= 5+1

=6

How are seeds produced

Answers

Answer:

From other seeds

Explanation:

They grow more seeds form the one seed

Answer:

From plant reproduction.

Explanation:

Plants produce flowers to make seeds. To make a seed a flower must be pollinated. Pollen from the male part of one flower travels to the female part of another flower where the seeds are made. Most, but not all plants, have both male and female parts inside one flower. The stigma is usually in the centre and the stamens, which produce the pollen, cluster around it. The petals act like an advertisement to attract various animals, which will carry the pollen from one flower to another.

3. The fact that the genetic code is universal suggests that:

B. Life forms have a common evolutionary ancestry.
C. Protein makes up the genetic material.
D. Evolution does not really occur.

Answers

Answer:

B. Life forms have a common evolutionary ancestry.

Explanation:

A. All organisms evolved from separate original ancestors.

-> We know this is not true. If organisms evolved from separate ancestors, they would have different genetic code.  

C. Protein makes up the genetic material.

-> This was proven false in Hershey–Chase experiment.

D. Evolution does not really occur.

->This one's obviously false as speciation happens regularly.

I WILL GIVE BRAINLIESTThe Pollution Problem by Roberto BererraUnfortunately, pollution is like air: its everywhere! Pollution is the introduction of harmful substances into the environment that can cause damage and harm to humans, animals, and the environment. It takes on a number of different forms, from chemicals and garbage to something as seemingly innocent as light or noise.Pollution comes from a variety of sources. In addition, it alters, changes, and even destroys a variety of places. For example, exhaust from cars pollutes the air. When it rains, runoff from fertilizers and pesticides, which farmers use to help crops grow, can pollute the water in oceans, rivers, lakes, and streams. Garbage dumped in landfills is not only an eyesore, but also a source of harmful gases that can damage the earths atmosphere. Light pollution, which comes in the form of bright streetlights or signs, disrupts the view of the night sky. Noise pollution caused by cars, trucks, and machines interrupts the natural sounds of the world around us, such as birds singing or leaves rustling.The types of pollution and their effects vary greatly. At the same time, however, they are related; each type of pollution affects the other types. An example of the connection between different types of pollution is acid rain. Acid rain is caused mostly by sulfur or nitrogen emissions given off by sources such as car exhaust and the burning of fossil fuels such as coal. These harmful chemicals rise into the atmosphere where they react with other compounds and then fall as an acidic form of rain, sleet, or snow. Acid rain damages plants and buildings, contaminates soil and water, and has a negative effect on animals, fish, and even humans.Pollution has other effects, too. Breathing toxic air or drinking polluted water can cause humans and animals to develop health problems that can be serious and sometimes deadly. The deaths of too many members of a certain species of animal can upset the local ecosystem, or the area in which they live. As a result, weather patterns and climates can also change.Though pollution is everywhere, there are ways to help prevent it. By walking or riding bikesinstead of driving carspeople can help decrease air pollution. People can also buy and eat organic foods to support farmers that do not use fertilizers on their crops. It is also a good idea to take old things that people intend to throw away and find new ways to use them. A great way to help the environment is to recycle. Save items like used paper, glass and plastic bottles, and metal cans. Then, take them to a recycling center where they can be turned into new products to be used again. Some cities and towns even have recycling programs in place so all you have to do is leave your recyclable items on the curb on a certain day each week. It doesnt get much easier to help the environment and reduce pollution than that!The statements below make persuasive appeals to the reader about the dangers of pollution. Some of the statements make appeals to logic (logos); some make appeals to emotion (pathos); and some make appeals to ethics or establish the authority of the speaker (ethos).
