It is possible to disrupt the plasma membrane by using enzymes and/or detergent agents.

The plasma membrane is a lipid bilayer that is mainly composed of phospholipids and cholesterol.

In laboratory conditions, it is possible to disrupt this lipid bilayer by using detergent and proteins (enzymes) that break the bonds binding phospholipids.

For example, enzymes can break down the double bonds that bind fatty acids in the lipid bilayer.

In conclusion, the plasma membrane can be break down by applying enzymes and detergents.

Integral membrane proteins are found on cell membranes and due to their structure and polar functional groups are able to serve as transport channels.

The cell membrane is a lipid bilayer which separates the cell contents from the external environment.

A component of the cell membrane is the integral membrane proteins which transverses the cell membrane and as such are able to serve as transport channels.

The integral membrane proteins contain hydrophilic amino acids groups with charged groups which help it to serve as binding site for polar molecules like water and ions.

The interior contains hydrophobic amino acid which enables it to interact  with the lipid bilayer.

In conclusion, the structure and composition of integral membrane proteins enables them to serve as cell transporters and channels.

The mutation does not affect the structure of the protein and is called a silent mutation.

A mutation is a change that occurs in the sequence of nucleotides of a gene.

The mutation that changes the base G in the DNA to A will result in the following corresponding changes in the mRNA and tRNA:

The mutation does not result in any changes since the amino acid coded for by the mRNA has more than one codon coding for it.

This type of mutation is called a silent mutation.

In conclusion, some mutations occurring in genes have no effect on the proteins the gene codes for.

According to the research, sodium moving into the muscle fiber simulates the sarcoplasmic reticulum to release calcium.

It is a cellular organelle present in muscle fibers in whose terminal muscle vesicles we will find calcium.

This calcium is what will be released when the action potential reaches the interior of the muscle cell through the T tubules.

Therefore, we can conclude that according to the research, sodium moving into the muscle fiber simulates the sarcoplasmic reticulum to release calcium.

Teeth, skulls, claws, and feathers are found in an owl pellet.

An owl pellet has indigestible material that is left in the gizzard i.e. teeth, skulls, claws, and feathers which are too dangerous to pass through the rest of the owl's digestive tract. In order to safely excrete this material, the owl's gizzard compacts it into a tight pellet that the owl regurgitates.

So we can conclude that teeth, skulls, claws, and feathers are found in an owl pellet.

Based on the model simulation of the carbon cycle, the atmospheric CO2 increases when you decrease the plant biomass.

The carbon cycle may be defined as the biogeochemical cycle by which carbon and its derivatives are swapped among the different zones of the Earth such as the biosphere, pedosphere, geosphere, hydrosphere, and atmosphere.

It is only the plant that uses CO2 for the production of food via the process of photosynthesis and converts it into atmospheric oxygen.

Once the biomass of the plant decreases, the atmospheric level of CO2 increases because now no one on the Earth has the ability to convert carbon dioxide into oxygen.

Therefore, based on the model simulation of the carbon cycle, the atmospheric CO2 increases when you decrease the plant biomass.

Fish populations and other aquatic resources are likely to be affected by changes in all of the above i.e., water temperatures, disease and water quality.

a) Water temperatures: Warm water released from industries into the rivers has lesser BOD (biological oxygen demand) than cool water. The marine species which are unable to migrate will die due to the unavailability of oxygen while frequent algal blooms will be present due to no availability of oxygen.

b) Diseases: Increase in toxins and chemicals will increase in the river as a result of the industrial dump. This will cause industrial animals to acquire toxicants in their bodies and will cause several diseases, wounds, and eventually the death of the organism.

c)  Water quality: due to warm and toxic water many marine animals will migrate to places with cooler water. there will be increased algal blooms. This will affect the whole food web and hence there will be a loss of biodiversity.

hence all of the above factors will affect Fish populations and other aquatic resources.

Answer:

I think it is making an observation and asking a question

Scientific methods are the procedural steps that involve experimentation to reach conclusion. The method best represents the observations and asking of questions. Thus, option B is correct.

The scientific method has been defined as the multistep process that involves various method procedures, including the questions, research topic issues, hypothesis, experimental and research tests, analysis of data, and drawing of conclusions.

The scientific method primarily starts with a question about the subject matter that needs to be solved for which the research is performed and a hypothesis is given. After a hypothesis, is established experiments are conducted so as to make observations.

The observations are then analyzed to draw conclusions to present the findings. This interpretation gives the solution to the presented problems. The biologist was asking questions when he observed and compared the population of the frogs in the first and second years.
