Which type of microscope would be the best tool to use to view the surface of a bacterial cell? Why?
Answer:
Electron Microscope
Explanation:
The maximum theoretical resolution of images created by light microscopes is ultimately limited by the wavelengths of visible light. Most light microscopes can only magnify 1000×, and a few can magnify up to 1500×, but this does not begin to approach the magnifying power of an electron microscope (EM), which uses short-wavelength electron beams rather than light to increase magnification and resolution.
-The electron microscope can achieve a much greater resolution than that obtained with the light microscope because the wavelength of electrons is shorter than that of light.
An Electron microscope is the type of microscope that would be the best tool to use to view the surface of a bacterial cell.
What is a Microscope?A microscope may be defined as an instrument that utilizes the arrangements of lenses to make an enlarged image of a small object.
An Electron microscope produces a higher resolution of bacterial cells as compared to a standard light microscope. This is because electrons possess a much shorter wavelength than visible light.
Therefore, the correct answer to this question is an Electron microscope.

Tara placed a grape in a solution, after sometime she noticed that the grape started to shrink.
a. Name the solution and explain.
b. Then Tara placed the raisin in a solution and noticed it started to swell up. Name the solution and explain
Answer:
a. Hypertonic solution
b. Hypotonic solution
Explanation:
There are basically 3 types of solutions in biology,
1) Isotonic-Same concentration of solute and solvent inside the grape and in the solution.
2)Hypotonic solution-More concentration of solvent in the solution than in the grape.
3)Hypertonic solution-More concentration of solvent in the grape than in the solution.
Now,
a. Tara had kept the grape in a hypertonic solution. The solvent will start draining from the grape to equalize the concentrations of solvent inside and outside. So, the grape shrank due to loss of water.
b. Tara kept it in a hypotonic solution. The solvent will start entering the grape to equalize the concentrations of solvent. So, the grape started swelling.

Which option identifies ways that people positively affect Earth’s resources?
Answer:
c is the correct answer on EDGE2020
There are many ways by which humans can positively impact Earth's resources. These include reforestation, reducing pollution, protection of endangered species, and mindful use of water and attempts to replenish the water bodies, etc.
What are the earth's resources?The resources present on earth which were not formed due to any kind of human intervention are called earth's resources or earth's natural resources. There are various natural resources found on earth.
Energy resources like petroleum and natural gas, metallic resources like iron, copper, and gold, and nonmetallic resources like granite, sandstone, etc are some of the examples of various resources found on earth.
However, due to the rise in consumerism, these resources are being overexploited by humans which have resulted in their depletion.
But, the awareness of this is spreading fast and humans have adopted various measures to prevent negative impacts and induce positive impacts on the resources of the earth.
Therefore, humans can have a positive impact on Earth's resources.

Question 7 of 10
A certain plant has a color that can range from green to yellow. Some plants
are very green, and some are very yellow, but most are in between. What is
most likely true about this trait?
A. The color is a Mendelian trait.
B. There are several genes that control the color.
C. There are only two alleles for color.
D. Being yellow is a recessive trait.
Answer:
B. There are several genes that control the color.
Explanation:
According to the description of the trait in this question in which the plant exhibits a wide range of colors from green to yellow, it shows that the trait for color in such plant is controlled by two or more (several) genes. This kind of inheritance is called a POLYGENIC INHERITANCE.
Polygenic inheritance is a kind of non-mendelian inheritance (does not follow the principles of Mendel) in which phenotypic traits of an organism is controlled by several genes. Each gene possess two alleles, which equally contribute to the phenotypic expression of such trait. Traits controlled by polygenes do not conform to Mendel's laws of inheritance as the offsprings exhibit a range of traits from the mixture of parental traits as stated in the question.
In polygenic inheritance, most of the offsprings exhibit the intermediate phenotype (between green and yellow) with few extremes (green and yellow) due to a combination of the genes in the parental phenotypes. Hence, based on the description in the question, there are several genes that control the color trait in the plant.
Answer: B. There are several genes that control the color.

You are the lucky student of a wacky professor who develops a time machine. He asks if you will test it with him. You get in and there is an immediate glitch–the date readout fails so that when you land you are not sure what era you are in. As your time machine lands, you see an unusual landscape before you. As you open the door you realize you cannot breathe. You quickly shut the door, realizing you are in the _____.
1) Archaean eon
2) Cambrian period
3) Cenozoic era
4) Mesozoic era
Answer: Option 1 is the correct answer
Archaean eon
Explanation:
You are in the Archean Eon era because the it was early in the Archean that life first appeared on Earth. The most two earlier of the formal divisions of Precambrian time (about 4.6 billion to 541 million years ago) and the period when life first formed on Earth It began about 4 billion years ago with the formation of Earth’s crust and enlongated to the begining of the Proterozoic Eon 2.5 billion years ago; the latter is the second formal division of Precambrian time.
In the Archean eon there are unsual landscapes no rocks are preserved from this stage. The earliest terrestrial materials are not rocks but minerals.
Throughout the Archean, oceanic and island arc crust was produced semi-half way.
You cannot breathe because there was no oxygen on the Earth. Oxygen was only present in compounds such as water and chemical reactions change to carbon containing molecules that form simple living cells that does not require oxygen.

When many nucleotides link together, they form a biomolecule responsible for storing genetic information called nucleic acids. Thus, the correct option is B.
What are Nucleotides?Nucleotides may be defined as the basic unit of the polynucleotide chain of nucleic acids such as DNA or RNA. Each nucleotide is composed of three components. They are as follows:
A nitrogenous base.A pentose sugar (ribose in the case of RNA, and deoxyribose in the case of DNA).A phosphate group.Nucleotides are the monomers of nucleic acids. Each nucleotide is joined together by covalent bonds known as phosphodiester linkage. This linkage is present between the phosphate group of one nucleotide and the third carbon atom of the pentose sugar of next nucleotide.
Therefore, nucleic acids are formed when many nucleotides link together which are responsible for storing the genetic information.

It corresponds to the formula of an acid oxide and a basic oxide:
Select one:
A. P2O3 y BaO
B. Mag y N2O5
C. FeO Y SO3
D. HNO y CaO
Answer:
P2O3 y BaO
Explanation:
The oxides of the main group metals are basic in nature. They form alkaline solutions when dissolved in water. Similarly, the oxides of main group non metals form acidic solutions when dissolved in water.
P2O5 is an oxide of a main group nonmetallic element in group 15. We expect this oxide to be acidic and form acids when dissolved in water as expected from the chemistry of the group.
Also, BaO is an oxide of barium, a group two main group metal. Hence we expect this oxide to be basic in nature and form alkaline solutions.
