Define sickle cell.
Who is a sickler?
Answer:
Sickle cell disease is an inherited blood disorder that turns normal, round blood cells into misshaped cells that look like sickles or crescent moons. These sickled cells can get stuck in blood vessels, blocking blood flow and causing severe pain as well as damage to organs, muscles, and bones. Sickle cell disease is inherited, passed from parent to child. Children with sickle cell disease have two defective genes, one from each parent. A child born with sickle cell trait inherited one defective gene from one parent, and a normal gene from the other parent. These children don't have sickle cell disease but are carriers of the defective gene and may pass it on to their children.

Which of the following is a main difference when comparing an animal cell and a plant cell?
3. Consider the technology behind each type of
microscope. Why can light microscopes produce
images in their natural color, while scanning
electron and transmission electron microscopes
only produce grayscale images?
Answer:
See the answer below
Explanation:
The light microscope uses visible light to produce images of objects on its slide while the electron microscope uses beams of electrons to project the image of specimens. Color is a property of photons of light, hence, the light microscope is able to produce images of specimens in their natural colors
The areas of the specimen on an electron microscope in which the beams of electron pass through usually appear white while other areas appear black. Hence, the electron microscopes can only produce grayscale images of specimens unless a false color is added to make the images visually appealing.
Scanning electron and transmission electron microscopes only produce grayscale images because electrons do not have colors.
Electrons can emit energy in the form of light when they return to a lower energy level. The color depends on the difference in energy between the two different levels.The color is a property of light, thereby light microscopes that use visible light to generate images can produce colored images.Conversely, scanning and transmission electron microscopes use an electron beam to image a sample, which does not record any color value.In conclusion, scanning electron and transmission electron microscopes only produce grayscale images because electrons do not have colors.

What are electron energy levels? Where are they located?
The electrons surrounding an atom are located in regions around the nucleus called “energy levels”. An energy level represents the 3-dimensional space surrounding the nucleus where electrons are most likely to be. The first energy level is closest to the nucleus.
Answer: Located in regions around the nucleus.
Explanation: Energy levels (also called electron shells) are fixed distances from the nucleus of an atom where electrons may be found. As you go farther from the nucleus, electrons at higher energy levels have more energy. The electron energy levels are an atom located in regions around the nucleus. An energy level represents the 3-dimensional space surrounding the nucleus where electrons are most likely to be. The first energy level is closest to the nucleus. The second energy level is a little farther away than the first.

what is the charge of an ion with 16 protons and 14 electrons? helppppppp
Answer:
Thus, each atom or ion of sulfur must contain 16 protons. We are told that the ion also has 16 neutrons, meaning the mass number of the ion is 16 + 16 = 32. Because the ion has 16 protons and 14 electrons, its net charge is 2–. Thus, the symbol for the ion is 32S2–.
Explanation:
The charge of an ion with 16 protons and 14 electrons is positive.
What is an ion?An ion is a gross electrically charged atom or a molecule. By convention, the charge of an electron is considered to be negative, and this charge is equal to and opposite to the charge of a proton, which is considered to be positive.
Ions are formed by adding or removing electrons from neutral atoms, molecules, or other ions; or by combining ions with other particles.
When atoms gain or lose electrons, ions form. Because electrons are negatively charged, losing one or more electrons causes an atom to become positively charged.
Gaining one or more electrons causes an atom to become negatively charged. The attraction between positively and negatively charged ions is known as ionic bonding.
Thus, the ion here is positive as it have more protons than electron.

ATP provides energy needed to carry out many cellular functions. Which of the following processes does NOT require ATP? A. active transport of a protein across a membrane B. making more ATP C. passive transport of oxygen across a cell membrane D. muscle contractions
ATP provides energy needed to carry out many cellular functions. Passive transport of oxygen across a cell membrane is does not require ATP. Hence option C is correct.
What is cellular function?Cellular function is defined as protein synthesis, translocation of molecules across the cell membrane, and cell division to create new cells. They provide the body with structure, take in food's nutrients, convert them into energy, and carry out certain functions. Additionally, cells have the ability to replicate themselves and contain the body's genetic material.
In primary active transport, molecules are moved across a membrane against their gradient directly using a chemical energy source (such as ATP). Ion transport, muscular contraction, nerve impulse transmission, substrate phosphorylation, and chemical synthesis are just a few of the processes that use ATP as an energy source. By adding a phosphate group to another molecule, ATP can drive biological operations.
Thus, ATP provides energy needed to carry out many cellular functions. Passive transport of oxygen across a cell membrane is does not require ATP. Hence option C is correct.
