Answer:

Inorganic fertilizers are not entirely composed of the nutrients needed by the plants. It also contains salts and other compounds. These are not absorbed by the plants so they are left behind in the soil and build up over time.

Answer:

The correct answer is - Greater sciatic notch

Explanation:

The greater sciatic notch is a notch in one of the pelvic bones n the human called the ilium. It is located between the posterior inferior iliac spine, and the auricular surface or ischial spine. It is the passageway through the pelvis into the thigh and posterior side.

Answer:

Greater sciatic notch

Explanation:

The greater sciatic notch allow the sciatic nerve to enter the thigh

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.

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.

Cellulose and starch are macromolecule polysaccharide carbohydrate made of glucose chains. It stabilizes plant cell walls and provides energy. Therefore , option (A) is correct.

Carbohydrates are renowned for their crucial function in plants, which is to provide key sources of energy and carbon skeletons for organic compounds and storage components. Carbohydrates are formed through the process of photosynthesis.

Starches and cellulose are both types of carbohydrates that belong to the larger class of polysaccharides since they are made up of long chains of glucose molecules. Although they are comparable, the human body is only able to make use of starches as a source of energy, whereas cellulose provides structure to plant cell wall.

Answer:

Explanation:

Let T = tall allele (dominant), t = short allele

True breeds are homo-zygous.

So the gardener is crossing TT with tt, with the resulting genotype of F1 all equal to Tt, i.e. all Tall hetero-zygous.

When the F1 pea plants are allowed to self-polinate, F2 results in Tt crossing with Tt, with the genotypes TT, Tt, tT and tt, and phenotypes 75% tall and 25% short, tall being dominant.

The container in which the snails are found will experience a decrease in oxygen level.(Option 2)

Animals require to take in oxygen in order to breakdown complex food materials during the process of metabolism. Unlike plants that take in carbon dioxide, animals take in oxygen.

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.

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.

The polar jet stream moves south is accompanies a cold spell in Minnesota. Therefore, option (A) is correct.

Polar jet stream is a belt of strong upper-level breezes that sits on the polar front. The winds generally move in a westerly direction in midlatitudes and are strongest at the tropopause, the upper boundary of the troposphere.

The convergence of cold air masses coming down from the Arctic and warm air coming up from the tropics creates the jet. Profound box and soak edges arise as the denser virus air sinks and redirects warm air locales north, giving the fly stream its wavy appearance.

The northern polar jet stream is the most important jet stream for aviation and weather forecasting on Earth because it is much stronger and lower in altitude than the subtropical jet streams.

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.
