Are viruses alive?

Answers

Answer 1
Most biologists say no they are not
Answer 2

Answer: As for now, no, it is not clarified but most biologists say no. Because viruses don’t grow, aren’t made out of cells, can’t stay in a stable state, nor can they make their own energy. Most living things do these things, so the are classified as nonliving.

Hope this helps, good luck! :)

Proteins are important food nutrients. A technician working at a food company is interested in the nutritional content of seeds/nuts. She runs a PAGE with samples from two different seed extracts. She runs multiple lanes of the staples. The gel is stained with Coomassie Blue. Seed extract No. 1 has three faint bands at 25, 30, and 35 kDa. Extract No. 2 has two bands at 25 and 35 kDa, and the bands are very dark. What might she conclude from her results about the nutritional value of the seed extracts

Answers

Answer: Sample 1 then, has more variety of proteins but less quantity of each one, while sample 2 has less variety but more quantity of the two proteins present.

Explanation:

Proteins are molecules found in the cells of all living organisms. A protein is composed of monomers called amino acids linked together by peptide bonds. To analyze proteins, a technique called SDS-PAGE (sodium dodecyl sulfate polyacrylamide gel electrophoresis) is used. This technique is used to separate proteins according to their electrophoretic mobility, depending on polypeptide chain length, molecular mass, post-translational modifications and other factors. SDS (sodium dodecylsulfate) is an anionic surfactant compound that breaks non-covalent bonds in proteins, denatures them causing these protein molecules to lose their native conformation and provides the polypeptide with a negative charge that is proportional to the chain length (the number of amino acids) and, therefore, to the molecular mass of the protein. The electrostatic repulsion created by the binding of SDS to the protein is one of the causes of the protein losing its native conformation, thus eliminating the differences in conformation of the different proteins to be separated in the gel.

An electric current is applied to the gel where the proteins are seeded, causing the negatively charged proteins to migrate through the gel in the direction of the anode (positively charged region). Short proteins will move more easily and faster through the pores of the gel, while larger proteins will find it more difficult to do so. After a certain time, the proteins will have migrated according to their size (measured in kDa or kiloDaltons). After electrophoresis, the gel should be stained with Coomassie blue or silver stain, allowing visualization of the separated proteins. After staining, the different proteins will appear as distinct bands on the gel. In addition, the higher the amount of a protein, the more intense the color of its band will be.

Extract No. 1 shows three bands: 25, 30 and 35 kDa. This means that it has three different proteins, each with a different molecular weight. Extract number 2 shows two bands: 25 and 35 kDa. It means that this sample has only 2 proteins. And being bands of higher intensity, we can say that there is more of each protein.

Sample 1 then, has more variety of proteins but less quantity of each one, while sample 2 has less variety but more quantity of the two proteins present.

Why do structural similarities between living things point to common ancestry?

Explanation:

Comparative anatomy is the study of the similarities and differences in the structures of different species. Similar body parts may be homologies or analogies.

Garlic mustard has been introduced to the beetles ecosystem. Describe what would happen to the beetles population as a result and explain why.

Answers

Answer:

It would collapse

Explanation:

Garlic mustard also produces root exudates that inhibit the growth of important soil fungi and leaf chemicals that kill native butterfly larvae that feed on the plant

In addition, invertebrates and other consumers that rely on these natural plant species for food are harmed by the spread of this invasive "weed". Garlic mustard also produces root exudates that inhibit the growth of important soil fungi and leaf chemicals that kill native butterfly larvae that feed on the plan

Garlic mustard is an invasive plant species that is known to negatively impact native plant populations in ecosystems.

What is invasive plant?

An invasive plant is a non-native plant species that is introduced to an ecosystem and has the ability to spread and negatively impact native plant and animal populations.

Garlic mustard is known to release chemicals that inhibit the growth of other plant species, including some that the beetles may rely on for food.

This could lead to a reduction in food availability for the beetles, which may cause a decline in their population.

Additionally, if the beetles are not adapted to feeding on garlic mustard, they may not be able to digest or utilize the plant efficiently, leading to further declines in population.

Thus, the impact of garlic mustard on the beetle population will depend on the specific beetle species and the extent to which they rely on native plant species for food.

Cuando una celula se va a dividir, la cromatina se contrae y compacta y forma estructuras como la que se ve al lado. Diga qué nombre reciben estas estructuras y cuantas hay en una célula humana

Answers

Answer:

cromosomas

Explanation:

Los cromosomas son moléculas lineales de ADN que contienen parte o todo el material genético de un organismo. El ciclo celular se divide en dos etapas: 1-interfase o etapa de 'no división' y 2-división celular. Durante la interfase, las fibras de cromatina no poseen un grado de condensación suficiente como para hablar de cromosomas. Durante la primera etapa de división celular (es decir, durante la profase), las fibras de cromatina se condensan para formar estructuras compactas conocidas como 'cromosomas' los cuales serán distribuidos entre células hijas. Las células somáticas de los seres humanos son diploides (2n = 46 cromosomas), esto significa que contienen 23 pares de cromosomas homólogos los cuales se alinean durante la metafase de la mitosis en la placa ecuatorial de la célula para ser distribuidos equitativamente entre células hijas durante las fases posteriores del ciclo celular (anafase, telofase y citocinesis). Por otra parte, las células germinales o gametos (espermatozoides masculinos y los óvulos femeninos) son haploides (n = 23 cromosomas) las cuales contienen un sólo set completo de cromosomas.

Describe how the jump rope could be used to model the cell membrane of a plant
cell.

Answers

Answer: Plants can use the energy from sunlight to turn water and carbon dioxide into. When the cell has enough organelles to make two cells, the division process starts. Let's discuss the process of photosynthesis again, this time taking a closer look at it. Just A long rope to represent the cell wall.

Jump rope is thin and elastic which is made by twisting two threads together which somewhat looks like a cell membrane can be used as a model for plant cell membrane.

What is cell?"The cell is structural and functional unit of life."Every organisms are made up of one or more number of cells.Each cell have various organelles that perform specific functions.What is cell membrane?"It is the outer layer of cell that separates interior of the cells to their surroundings."It is thin and flexible.Cell membrane is composed of bilipid layer in which proteins are embedded on it.It act as a semi-permeable membrane that only only specific molecules to pass through it.

Answer:

In the presence of lidocaine, the action potential was NOT affected at R1 because lidocaine was applied downstream of R1

Explanation:

Lidocaine is an anesthetic that has the power to neutralize neuromal membranes. This anesthetic power allows the ionic fluxes capable of stimulating impulses to be diffused and this allows a dormancy to be achieved. However, when lidocaine is applied downstream to a molecule or structure, the action potential of that structure or molecule is not affected and it may continue to receive impulses.
