Base your answers to questions 14 and 15 on the information in the diagram below and on your knowledge of biology. A) Finches with crushing bills eat only animals for food. B) Finches that eat animals always have larger beaks than finches that eat plants. C) Finches with grasping bills usually eat animals for food. D) Finches that eat plants all have very large beaks. 14. Based on the information in the chart, which statement is correct

Answers

Answer:

D) Finches that eat plants all have very large beaks.

Explanation:

Finches that eat plants have very large beaks because plants are big in size which can only be eaten with large beak. Those finches that lives in the environment having nuts and seeds having large beaks due to the big size of seeds and plant parts so that's why we can say that finches who feeds on plants parts have larger beaks as compared to those finches who feeds on insects.

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.

What are two ways that meiosis contributes to genetic variation? How do these two ways lead to variation?

Answers

Answer:

During prophase of meiosis I, the double-chromatid homologous pairs of chromosomes cross over with each other and often exchange chromosome segments. This recombination creates genetic diversity by allowing genes from each parent to intermix, resulting in chromosomes with a different genetic complement.Hope this is fine for you!!

Que sucedería con la especie humana si debido a una futura mutación genética sus células no pudieran realizar los procesos de mitosis y meiosis

Answers

Answer:

la vida no podría continuar sin los procesos de división celular  

Explanation:

La mitosis es el proceso de división celular mediante el cual se producen dos células idénticas a partir de una sola célula. Durante la mitosis la célula crece y duplica la cantidad de ADN, con lo cual exactamente el mismo contenido de información genética es trasmitido a las sucesivas células que el proceso de mitosis va a dar origen. Por otra parte, la meiosis es un proceso celular en el cual se producen dos divisiones nucleares y citoplasmáticas (meiosis I y meiosis II) las cuales son precedidas por una fase de replicación del ADN. En la especie humana, la mitosis da lugar a células diploides (2n) con dos set completos de cromosomas homólogos, mientras que la meiosis da lugar a cuatro células haploides (n) llamadas gametos (el gameto masculino es el espermatozoide y el gameto femenino es el óvulo) las cuales contienen la mitad del número cromosómico al de la célula de origen. En organismos eucariotas pluricelulares tales como la especie humana, la función de la mitosis es producir más células somáticas (soma: cuerpo) con idéntico material genético, mientras que la función de la meiosis es producir células aptas para el proceso de reproducción, es decir, células con la mitad del material genético que se fusionarán para generar una célula diploide o zigoto a partir del cual y mediante sucesivas mitosis se desarrollará un organismo adulto.

What are the two main types of minerals?

Answers

Answer:

The two main types of minerals are macro minerals and trace minerals.

Explanation:

Macro means large in Greek. And your body needs larger amounts of macro minerals. Calcium, phosphorus, magnesium, sodium, potassium, chloride, and sulfur make up the macro mineral group.

A trace of anything indicates that only a small amount of it exists. Even while your body requires trace minerals, it only requires a small amount of each. Iron, manganese, copper, iodine, zinc, cobalt, fluoride, and selenium are examples of trace minerals.

Explain the general distribution of life in aquatic systems as a function of chemistry, geography, light, depth, salinity, and temperature.

Answers

Different types of organisms can exist in a variety of aquatic environments due to the fact that they can vary significantly from place to place and that organisms within each water system will have evolved to adapt to their specific environment.

How does light affect aquatic life?

Sunlight plays a vital role in the ocean’s ecosystem. First, sunlight enters the water column, warms it, creates currents, and is then absorbed by phosphorous-rich phytoplanktons. Phytoplanktons use the energy captured by phototrophs (pigments like chlorophylls) to convert water and nutrients into organic matter.

Light availability determines the types of organisms that can live in a particular part of an aquatic environment. The deeper the water depth, the less light it can penetrate until there is no light at all.

The salinity of water affects its density which in turn affects the movement of ocean currents. It may also affect marine life which needs to regulate the intake of salt water. There is a relationship between salinity, temperature, and water density. Therefore, any change in temperature or water density will affect the salinity of the water in the area.

Water chemistry parameters (pH, dissolved organic carbon, and hardness) play a role in metal toxicity by influencing the bioavailability of aquatic species of metals in water.
