Why are onion root tips a good choice for viewing cells in different stages of the cell cycle?
The onion root tips are good for observing cells in different stages of cell cycle as they comprise of different cells in different stages of growth and development.
The onion root tip is an actively growing region of the onion plant. The cells are expected to be in different stages of growth and maturation. The cells are in different stages of mitosis which can be observed microscopically. The onion root tip can be prepared for microscopic examination by squashing and flattening of the onion root tip. The chromosomes during different stages of mitosis can be observed by using staining with specific dyes like Feulgen stain and Acetocarmine stain.Learn more about cell cycle:

You are involved in an experiment involving fluorescent painting of chromosomes. You observe the following in a nucleus experiencing homologous pairing in metaphase I of meiosis. At appears that four chromosomes have become paired, with each chromosome pairing with two others (centromeres appear as white circles, and the four chromosomes appear in different colors). What is the best explanation of this finding
Answer:
It seems that a reciprocal translocation is going on.
Explanation:
A translocation occurs when a chromosomal fragment changes its location in the same chromosome from the original to a new one. Or when it leaves the chromosome to re-locate in a new different chromosome.
According to this, there are different types of translocations:
Intrachromosomal translocations: Intra-radial: the change in position occurs in the same arm of the chromosome. For instance, 123.456789 → 123.478569Extra-radial: The change in position occurs from one arm to the other of the same chromosome. For instance, 123.456789 → 15623.4789Extrachromosomal translocations:Transposition: not reciprocal interchange. The fragment leaves a chromosome to re-locate in another chromosome. The other chromosome does not send any fragment to the first one. Reciprocal translocation: There is a reciprocal interchange. A fragment of chromosome A goes to B, and a fragment of chromosome B goes to A.Reciprocal translocations might be:
Fraternal: the interchange occurs among homologous chromosomesExternal: the interchange occurs among non-homologous chromosomesReciprocal translocations are easily recognized during meiosis because an association between four chromosomes can be observed. This association is a quadrivalent structure.
During metaphase 1, the centromeres involved in the quadrivalent originate centromeric co-orientation or disjunction.

Explanation:
Why do you think that the shape of the different types of fatty acid molecules affects how easily they solidify?
Answer:
Fats are actually a type of lipid. Lipids are a major class of biochemical compounds that includes oils as well as fats. Organisms use lipids to store energy and for many other uses.
Lipid molecules consist mainly of repeating units called fatty acids. There are two types of fatty acids: saturated fatty acids and unsaturated fatty acids. Both types consist mainly of simple chains of carbon atoms bonded to one another and to hydrogen atoms. The two types of fatty acids differ in how many hydrogen atoms they contain.
Explanation:
Can I plz have brainliest
The shape of the types of fatty acid molecules has an impact on their solidification.
It should be noted that in the unsaturated fatty acid, there is at least a double bond in its string. The carbon atoms that are joined by the bonds lead to the change in their shapes.
While saturated fatty acids have a linear structure, the unsaturated fatty acids kink or bend in order to form double bonds within the chemical foundation.

Name two reasons that viruses are considered nonliving.
Answer:
The virus simply can't replicate. Viruses fail the second question for the same reason. ... Finally, a virus isn't considered living because it doesn't need to consume energy to survive, nor is it able to regulate its own temperature. Viruses are not made out of cells, they can't keep themselves in a stable state, they don't grow, and they can't make their own energy. Even though they definitely replicate and adapt to their environment, viruses are more like androids than real living organisms.
Explanation:
Viruses, like bacteria, are microscopic and cause human diseases. ... Viruses also lack the properties of living things: They have no energy metabolism, they do not grow, they produce no waste products, and they do not respond to stimuli. They also don't reproduce independently but must replicate by invading living cells.

factors that affect temperature requirements of aquatic species
Answer:
Heat transfer, whether from the air, sunlight, another water source or thermal pollution can change the temperature of water. Water temperature plays a major role in the quality of aquatic life and habitats. Heat flow and the fluctuation of temperature determine what species will live and thrive in a body of water.

Answer: 1. In CF, the body makes abnormal CFTR protein or none at all. Without normal CFTR protein, the cells lining the pathways (tubes) inside some organs make thick, sticky mucus rather than the normal thin, watery kind. Thick mucus can trap bacteria in the lungs, leading to infection, inflammation, and breathing problems. 2. When the CFTR protein is defective, epithelial cells can't regulate the way that chloride (part of the salt called sodium chloride) passes across cell membranes. 3. Mutations in the DMD gene cause the Duchenne and Becker forms of muscular dystrophy. The DMD gene provides instructions for making a protein called dystrophin . This protein is located primarily in skeletal and cardiac muscle, where it helps stabilize and protect muscle fibers. Collapse Section. DMD, the largest known human gene, provides instructions for making a protein called dystrophin. This protein is located primarily in muscles used for movement (skeletal muscles) and in heart (cardiac) muscle. 4. Lack of the dystrophin protein in muscle cells causes them to be fragile and easily damaged. DMD carriers are females who have a normal dystrophin gene on one X chromosome and an abnormal dystrophin gene on the other X chromosome. Most carriers of DMD do not themselves have signs and symptoms of the disease, but a minority do. Symptoms can range from mild skeletal muscle weakness or cardiac involvement to severe weakness or cardiac effects and can begin in childhood or adulthood. 5. Scurvy happens when there is a lack of vitamin C, or ascorbic acid. The deficiency leads to symptoms of weakness, anemia, gum disease, and skin problems. This is because vitamin C is needed for making collagen, an important component in connective tissues. 6. composed of ground substance and fibers. The extracellular matrix of connective tissue is composed of ground substance and fibers. In ordinary connective tissue, the ground substance consists mainly of water. The principal fiber type is collagen (the most abundant protein in the body), with elastic fibers as a minor element. brainliest?

why is protein synthesis diffrent in prokaryotes and eukaryotes?
Answer:
In prokaryotes, translation occurs in the cytoplasm, where the large and small subunits of the ribosome bind to the mRNA. In eukaryotes, translation occurs in the cytosol or across the membrane of the endoplasmic reticulum where the entire ribosome/mRNA complex binds to the outer membrane of the rough endoplasmic reticulum and the new protein is synthesized and released into the ER; the newly created polypeptide can be stored inside the ER for future vesicle transport and secretion outside the cell, or immediately secreted.
