Answer:

7.5mL

Explanation:

Comsidering the definition of dilution, 7.5 mL of the stock solution  of 2 M are required to prepare 100 mL of 0.150 M solution.

Dilution is a procedure by which the concentration of a solution is lowered. It is achieved by adding more solvent to the same amount of solute.

Then the amount of solute does not vary, but the volume of the solvent does: when more solvent is added, the concentration of the solute decreases, as the volume of the solution increases.

A dilution is mathematically expressed as:

Ci×Vi = Cf×Vf

where

In this case, you know:

Replacing in the definition of dilution:  

2 M×Vi= 0.150 M×100 mL

Solving:

[tex]Vi=\frac{0.150 M x 100 mL}{2 M}[/tex]

Vi= 7.5 mL

In summary, 7.5 mL of the stock solution  of 2 M are required to prepare 100 mL of 0.150 M solution.

The negative health impacts of indoor pollution are caused by ultrafine particles that are inhaled and absorbed by the lungs. So, the correct options are A and C.

Indoor air pollution, which can be as much as ten times worse than outside air pollution, is indeed the degradation in indoor air quality caused by hazardous chemicals and other elements. This is because enclosed rooms encourage the accumulation of possible contaminants more than do open ones.

The main contributors to indoor air pollution include: Bioaerosols, building materials, and combustion Although radon, asbestos, pesticides, toxic substances, organic volatile compounds, and environmental tobacco smoke are all regarded as serious indoor pollutants in industrialised countries, developing countries are primarily affected by the combustion byproducts of biomass fuels.

The negative health impacts of indoor pollution are caused by ultrafine particles that are inhaled and absorbed by the lungs.

Therefore, the correct options are A and C.

Explanation:

Agarose has a large pore size and is suitable for separating nucleic acids and large protein complexes. ... SDS-PAGE separates proteins primarily by mass because the ionic detergent SDS denatures and binds to proteins to make them uniformly negatively charged.

In this question we will differentiate between agarose gel electrophoresis and SDS-PAGE based on the composition of gels and Dye used for staining.

The gel matrix is ​​created by dissolving a natural polysaccharide called dye-free agarose, which is derived from a type of seaweed, in a conductive buffer, in the approximate proportion of 1% to 3% agarose.

Polyacrylamide gel electrophoresis (PAGE) with sodium dodecyl sulfate (SDS). SDS-PAGE consists of a type of electrophoresis performed under denaturing conditions for the separation of proteins without dyes.

Whit this information, we can conclude that differentiate between agarose gel electrophoresis and SDS-PAGE based on the composition of gels and Dye used for staining.

Explanation:

Answer:

The sample obtained for the study is not enough. Also, a control group is not established thus making the study erroneous.

Explanation:

The total sample size of 4 specimens from each of the two groups does not qualify as an appropriate sample size for the generalization of the results. Furthermore, the mixing of different ages and genders is not suitable for this kind of sample.

Also, the control group is not established where healthy specimens are kept in a similar environment to factor out the effects of the environment and other components on the health/death of the animals.

Answer:

Phases: G1, S phase and G2

Functions:

- G1: cell grows

- S phase: DNA replication

- G1: organelle replication and increase of the cytoplasmatic proteins

Explanation:

Interphase is the phase of the cell cycle in which the cell prepares for its division and ensures that each daughter cell has the correct required materials for cell survival (i.e., a correct amount of DNA, organelles, proteins, etc). Interphase can be divided into three subphases: Gap 1 (G1), Synthesis (S), and Gap 2 (G2). During G1 phase, the cell increases its size and replicates its organelles as necessary. During S phase, the cell growth continues, the DNA of the cell is replicated and rapidly assembled into chromatin. During G2 phase, the cell increases its cytoplasmatic content producing molecules it still needs to divide (e.g., essential M-cyclin molecules) and replicates its organelles (e.g., mitochondria in animals and chloroplasts in plants).

Answer: a frame shift mutation

Explanation:

ACGGGCAAACGATTG  to ACGGGCAACGATTG, and the mutation is a deletion mutation, as there is a deletion of the adenine base out of three adenines. as there is a deletion of a single base, ,so it is called a deletion mutation.

This change can have various effects on the resulting protein, depending on the specific location of the mutation within the gene and the role of the affected amino acid in the protein's function. For instance, in a non-coding region of the gene, such a mutation might have no effect at all on the protein, as it would not affect the sequence of the mRNA that is transcribed from the gene. However, if the mutation occurs in a coding region of the gene, it can lead to a change in the resulting protein.

Hence, ACGGGCAAACGATTG  to ACGGGCAACGATTG, and the mutation is a deletion mutation, as there is a deletion of the adenine base out of three adenines.

B sounds like a sensible choice

Explanation:

The extinct dinosaur and modern bird share a common ancestor. So the correct option is B.

Systematics, taxonomy, phylogenetics, and evolution are the four approaches used to investigate evolutionary connections. The branch of science known as systematics is concerned with classifying species and figuring out their relationships. It has two primary branches that may be separated:

Organisms are classified, given names, and grouped in taxonomy. A population, species, genus, or higher-level grouping like a family, order, class, phylum, kingdom, or domain can all be considered as a group or taxon. The word taxon is pluralized as taxa. The determination of evolutionary links or patterns of descent of species is via the study of phylogenetics.

The species of living things that exist now are all descendants of earlier ones. This is the result of evolution or merely time-related change. Branching evolutionary trees can be used to illustrate the evolutionary links between ancestors and their offspring. An evolutionary tree shows which ancestors gave rise to which descendants, much like your family tree does.

Therefore the correct option is B.

Answer:

The answer is C

Explanation:

Secondary succession often occurs after a disaster, the ecosystem is not as primary as the primary succession, so it will take shorter time to recover. New species will occur in this place, and rebuild a constant environment. C is exactly the situation.

Hope this will help❤️

The best example of secondary succession is when one species replaces another species in an ecosystem after a forest fire. The correct option is C.

Secondary succession is a type of ecological succession that occurs on substrates that already have soil, and at least some organisms residing on it, like a forest or a community that has been disrupted by wildfire, tornadoes, or hurricanes.

The secondary succession in an ecosystem happens when a primary community is destroyed, for example, by wildfire. In secondary succession, the soil, seeds, and rhizomes survived in the soil and provides the foundation for the new community that is about to develop.

The rate of secondary succession varies according to the time taken for the primary community to regenerate, the level of disturbance of the habitat, the availability of propagules, and the dispersal capability of the species involved.

Therefore, the correct option is C.

Answer:

a) Beaver-dam buildings → (iii) Pond floods

b) Forest fire → (i) New plants can grow because of an increase in sunlight on the forest floor

c) Lack of rainfall  →  (ii) Zebras migrate farther to find water holes

d) Invasive water plants arrive →  (iv) Sunlight is blocked for native seagrasses

e) Grasshopper outbreaks  →   (v) Crops are wiped out along the prairie

f) Coyote disease decreases the population →  (vi) Mice population explodes

Explanation:

a) Beaver-dam buildings → (iii) Pond floods

This is an example of how some species might produce damages in ecosystems. Beavers are known for their dams, where they hide from predators, find shelter, reproduce, and feed. With time, and as the beaver population grows, these dams get bigger each time. These animals keep cutting down trees and covering some wider areas that were inhabited previously by other species. The landscape changes, these areas get flooded permanently, most vegetation dye, the soil properties get altered, and just a few species can keep living there. The ecosystem changes.

b) Forest fire → (i) New plants can grow because of an increase in sunlight on the forest floor

This is an example of biological succession. Stable forests characterize as having big old trees that compete for light developing big canopies at heights. Poor light reaches the ground and allows some smaller species to grow. When a fire occurs, some of these trees might fall or disappear. These fire events open windows in the forest through which sunlight directly reaches the ground. Many new species can germinate and grow. There occurs a renovation of vegetable species in the forest and the consequent renovation of other living forms.  

c) Lack of rainfall  →  (ii) Zebras migrate farther to find water holes

It is not unusual that some species need to migrate looking for food or water. In certain areas, seasonal differences are very sharp, and while some periods characterize as producing plenty of food and water, some others characterize as lacking them, dry seasons especially. Animals develop different strategies to face these moments. Zebras need to migrate to find a new source of water to ensure proper hydration.

d) Invasive water plants arrive →  (iv) Sunlight is blocked for native seagrasses

A very known global environmental problem is the damage caused by invasive species. In a few words, exotic species arrive in a new area out of their native distribution range, establish, grow, adapt, and reproduce. These exotic species turn into invasive species when they overgrow, sharply increasing their reproductive rate. At this point, interaction with native species becomes harder, competing for resources such as space, light, food, shelter, water, among many others. Invasive species become such a good competitor that end by displacing native species. In the exposed example, invasive water plants arrive, and their population overgrows. They compete for light with native seagrasses and end by blocking it for them.

e) Grasshopper outbreaks  →   (v) Crops are wiped out along the prairie

This is an example of the prey-predator relationship. In this case, grasshoppers are the predators, and crops are acting as the prey. Whenever one of the population increases in size, the other one follows this increase, causing the decrease of the first one. When the first population decreases, the second one also decreases. In this example, grasshopper outbreaks, meaning an increase in predation rate over crops. Many more individuals are feeding on the crops, causing more damages to the plants´ population. Crops do not have enough time to recover, so they are wiped out.

f) Coyote disease decreases the population →  (vi) Mice population explodes

This is also an example of the prey-predator relationship. In this case, coyotes are the predators, and mice are acting as the prey. As coyotes are affected by the disease, which causes a decrease in their population size, mice seem to be favored, as they are not predated. They have enough time to recover as a population and increase in size. Coyotes´population decreases in size, so there are many fewer individuals feeding on mice, and hence, the mice population increases very fast. It explodes.
