HELP ME MAKE THIS ESSAY BETTERStructure and Function of MicroscopesA microscope is a laboratory instrument used to examine objects that are too small to be seen by the naked eye. There are several types of microscopes but in this essay, we will be discussing the compound light microscope, the transmission electron microscope, and the scanning electron microscope. And we will be comparing its structure and function.From its name compound light microscope uses light as its radiation source with a wavelength that reaches from 400 to 700 nm though the Transmission electron microscope uses electrons as its radiation source, the scanning electron microscope uses electrons as well which wavelength reaches 0.005 nm.For the lens, the compound light microscope uses glass that is have its maximum resolution of 200 nm and can view colored images with an eyepiece powered 10x and 3 or 4 objective lenses that are power can be (4x, 10x, 40x) power. both transmission electron microscope and scanning electron microscope uses Electromagnetic as their lens although transmission electron microscope lens maximum resolution is 1 nm, and its maximum magnification power is 250 000x with a monogram view and scanning electron microscope lens maximum resolution is 10 nm and its maximum magnification power is 100 000x with a monogram view as well.For the specimen, the compound light microscope supports both living and non-living specimens. The transmission electron microscope and the scanning electron microscope both support only non-living specimens although the transmission electron microscope supports it on a small copper grid in a vacuum, and the scanning electron microscope supports it on in a metal disc in a vacuum.In the end, all microscopes are useful without microscopes no medicines would be found because scientists would not know how to treat the micro viruses and bacteria, and we could not explore and discover micro-organisms around us that we cannot see with our naked eye.

how does a single genome code for so many types of tissues

Answers

Answer:

The genome of a cell contains in its DNA sequence the information to make many thousands of different protein and RNA molecules. A cell typically expresses only a fraction of its genes, and the different types of cells in multicellular organisms arise because different sets of genes are expressed.

The genome, which is the second layer, regulates gene access, allowing each cell type to activate its own unique genes while shutting off the majority of the others.

What is genome?

The complete set of DNA instructions present in a cell is known as the genome. The human genome is made up of 23 pairs of chromosomes that are found in the cell's nucleus and one tiny chromosome that is found in the mitochondria.

Everything a person needs to grow and operate is encoded in their genome. The DNA sequence in a cell's genome contains the instructions needed to create tens of thousands of different protein and RNA molecules.

Thus,  in multicellular organisms, distinct cell types develop because diverse sets of genes are expressed, even though a cell normally expresses just a portion of its genes.

Human cells have two sets of DNA in each cell. Thus, the correct option is A.

What is DNA?

DNA stands for Deoxyribonucleic acid. It is considered the genetic material of most organisms. It consists of base pairs like adenine, thymine, guanine, and cytosine.

Human cells have two sets of DNA in each cell, one came from the paternal side while the other came from the maternal side.

How can using a dam as a source of freshwater also harm wildlife?
A. Dams help control floodwaters.
B. Dams provide drinking water.
C. Dams displace existing habitats.
Ο Ο
D. Dams provide water recreation.

Answers

Answer:

c

Explanation:

because its the only one that would be hurting wild life.

Using a dam as a source of freshwater can harm wildlife by displacing existing habitats. Therefore, option (C) is correct.

What are the negative impacts of dams?

Dams often require the creation of reservoirs, which can submerge large areas of land and alter the natural flow of rivers and streams. This can lead to the loss of important habitats for fish, mammals, and other wildlife that rely on rivers and streams for food, shelter, and reproduction.

In addition, changes in water temperature, dissolved oxygen levels, and water flow can negatively impact aquatic ecosystems downstream from the dam.

These impacts can be mitigated through careful planning and management, such as the creation of fish ladders and other structures to help fish navigate past the dam, and the release of water at appropriate times to mimic natural flow patterns.

thinking about the components in pcr, do you think there are major differences in the process of dna replication between species?

Answers

The major difference in the process of DNA replication between species is the linear order of nucleotides, which can be amplified by PCR. This technique enables the amplification of specific DNA fragments.

The Polymerase chain reaction (PCR) is a technique widely used in molecular biology in order to amplify and thus identify small DNA fragments (approx. 1000 pb).

The PCR uses all materials required to carry out DNA replication: a thermostable DNA polymerase, primers (DNA oligonucleotides), deoxyribonucleotides (ddA, ddG, ddC, or ddT), and template DNA.

The template DNA indicates the linear order of nucleotides that will be added to the amplified DNA fragment, which is highly specific and may vary even between individuals of the same species.

What are lipids?

Lipids have three main biological activities in the body: they are essential signaling molecules, structural elements of cell membranes, and energy storage facilities.

Triacylglycerols (commonly known as triglycerides), phospholipids, and sterols are the three primary categories of lipids. Fats are subtypes of lipids that are typically composed of glycerol and fatty acid chains.

One sort of lipid, which includes fats, is a group of molecules that don't mix well with water. Hydrophobic, nonpolar, and primarily composed of hydrocarbon chains, lipids have a tendency to be.

Therefore, the correct option is D. They are the main structural components of membranes.

Answers

Answer:

Very large molecules such as proteins are too big to move through the cell membrane which is said to be impermeable to them. The type of transport proteins present in a cell membrane determines which substances the membrane is permeable to. CO2 molecules pass directly through phospholipids. Glucose molecules travel through the proteins.
