if it's online then you can turn it in on your phone just download Google classroom on your phone and you can copy and paste this but also don't use my full words because I used stuff from the internet

  • A:cell wall.....The cell wall surrounds the plasma membrane of plant cells and provides tensile strength and protection against mechanical and osmotic stress. It also allows cells to develop turgor pressure, which is the pressure of the cell contents against the cell wall.

  • C: cytoplasm ......The cytoplasm provides a medium for the organelles to remain suspended. The cytoplasm acts as a buffer and protects the genetic material of the cell and also the cellular organelles from damage caused due to movement and collision with other cells. Cellular respiration begins in the cytoplasm with glycolysis.

  • E:Golgi....The golgi apparatus is a membrane bound organelle found in most cells. It is responsible for packaging proteins into vesicles prior to secretion and therefore plays a key role in the secretory pathway.

  • G: smooth ER......The smooth endoplasmic reticulum functions in many metabolic processes. It synthesizes lipids, phospholipids as in plasma membranes, and steroids. Cells that secrete these products, such as cells of the testes, ovaries, and skin oil glands, have an excess of smooth endoplasmic reticulum.

  • H: rough ER/endoplasmic reticulum ......The endoplasmic reticulum can either be smooth or rough, and in general its function is to produce proteins for the rest of the cell to function. The rough endoplasmic reticulum has on it ribosomes, which are small, round organelles whose function it is to make those proteins.

  • I: nucleus......The nucleus has very important roles to play. As it contains genetic material, it coordinates cell activities like protein synthesis and cell division. Anatomically the nucleus is made up of several components: nuclear envelope, nuclear lamina, nucleolus, chromosomes, nucleoplasm are some of these components.

  • J: nucleolus........The nucleolus is the most conspicuous domain in the eukaryotic cell nucleus, whose main function is ribosomal RNA (rRNA) synthesis and ribosome biogenesis

  • K: cell membrane.......The plasma membrane, or the cell membrane, provides protection for a cell. It also provides a fixed environment inside the cell, and that membrane has several different functions. One is to transport nutrients into the cell and also to transport toxic substances out of the cell.

  • L: ribosomes.....Ribosomes have two main functions — decoding the message and the formation of peptide bonds. These two activities reside in two large ribonucleoprotein particles (RNPs) of unequal size, the ribosomal subunits. Each subunit is made of one or more ribosomal RNAs (rRNAs) and many ribosomal proteins (r-proteins).

please appreciate the effort because I tried to make the answers look good lol

How do protists, fungi, or plants potentially benefit or harm us? You should be able to find a pro and a con for each type of or
IgorLugansk [536]

Here are some potential benefits and harms of protists, fungi and plants:

  1. Protists:

Benefits: Some photosynthetic protists are one of the most important food source for many sea animals like sharks- the big giant aquatic creatures. They are responsible for producing 40% of the food that other organisms consume. Several little sea organisms like shrimp and larval crabs depend on protists for their food. Humans also harvest protests for food since they hold primary position in the food chain.

Harms: Like any other organisms, protists can also harm, especially to humans. There is a specific group of protists called animal-like protists that act as a parasite and harm human being.  

For example: a fatal disease malaria is caused by a protist called plasmodium that is transmitted to human through a mosquito bite. Malaria can cause symptoms like headaches, vomiting and fever, and in severe cases can lead to the death of individual.

     2. Fungi:

Benefits: Some fungi are very useful for humans like mushrooms. They are part of our delicious cuisines and add flavor and aroma to the food. Yeast is a fungi that is used to make bread and soya sauce. They are also source of useful compounds that scientists used to treat bacterial and viral infections.

Harms: Fungi can be really harmful to humans as well. They cause several diseases in humans and crops such as, Rusts and smuts on farm crops and orchards, Athletes foot and oral thrush in humans.

  3. Plants

Benefits: It won’t be wrong to say that we owe our existence to plants. They are not only important for humans but all other living organisms. Humans cannot survive more than few minutes without the supply for oxygen. Plants release the oxygen that humans use to breathe and survive.

Harms: Most of the plants are useful and just useful to us. They don’t eat us, run after us or kill us. However, some plants are so dangerous that only standing near them can cause harmful effects on human health. For example, the Manchineel tree is found throughout the Carribean and America, getting splash of its run off or inhaling its dust can quickly cause itching and swelling all over the skin. If you just touch its skin, your body will experience rashes quickly!

Hope it helps!

Explain how the terms oxidation and reduction apply even when there is only a partial shift of electrons between atoms linked by
aliina [53]

Explanation:

In a covalent bond, there is sharing of the donated electron by two atomic species having very small electronegative differences between them.

Oxidation is the loss of electrons by a specie and it usually lead to an increase in oxidation number.

Reduction is the gain of electrons by a specie. It leads to a lower oxidation number.

Since there is no actual loss of gain of electrons in a covalent body, the electronegativiy is at work.

Electronegativity is the ability of a specie to draw the shared electrons more to itself in a covalent bond.

  • Between two atoms bonded covalently, the more electronegative specie draws the electrons closer.
  • This leaves a partial negative charge on it.
  • The other electron then becomes partially positively charged.
  • We can then say, the more electronegative specie undergoes reduction.
  • The less electronegative one undergoes oxidation.

Which of the following terms would be used to indicate a patient is suffering from neuropathic pain?
Naddik [55]

Answer:

sensation and paresthesia

Explanation:

Sensation and paresthesia are the terms that would indicate a patient is suffering from neuropathic pain. Sensation is concrete, conscious experience resulting from stimulation of a specific sense organ or sensory nerve, or in the brain of an individual. Paresthesia is a type of abnormal sensation of the skin (tingling, chilling and burning etc) without any apparent physical cause in the body.
