assertion: empty milk pouches are biodegradable Reason: they cannot be used in biogas formation
Answer:
The pollutants like heavy metals, organic solvents present in pesticides exist in small amounts in the atmosphere. During the process of the food chain, the concentration of these pollutants progressively keeps on increasing through different trophic levels. For example, fish eats a lot of planktonic growth may retain the pollutants in their tissues, birds or people that eat the fish might concentrate the pollutants still more. This process of accumulation of pollutants at different trophic levels is called as biomagnification. So, the correct answer is 'Assertion is correct but Reason is incorrect'.

-trough
Answer:
- trough.
Explanation:
The Trough is the lowest wave section, the minimum wave part. It's the other way around from crest.A wave or alternating signal minimal point.A long, narrow depression, waves or ridges between them.A low point in a corporate cycle or on a graph.An extended area of relatively low pressure, often in conjunction with the front.the prime mover of inspiration is the blank during normal quiet breathing expiration is a passive process as this muscle relaxes into its original dome shape. provide conditions when expiration becomes an active process or forced. explain
Answer:
The prime agonist of inspiration is the diaphragm muscle.
The conditions when expiration becomes an active process is : Emphysema, Pneumonia, Bronchitis.
-Expiration is the passive process as there is elastic recoil of lungs following inspiration without contraction of any muscles.
-The elastic fibers in alveoli are damages or filled with mucus and fluid in the disease such as conditions such as emphysema or pneumonia.
-Elastic recoil of lungs.
-Hence, muscle contraction is required to forcefully exhale the air from lungs. Internal intercostal muscles contract to pull the ribs downward and remove air from the lungs.

Dark skin ( a result of increased melanin production in equatorial populations), is likely a response to ultraviolet radiation because UV radiation causes:
Answer: Skin cancer
Explanation:
Melanin is a pigment derived from an amino called acid tyrosine. The most common form of melanin is called eumelanin, which is a polymer of dihydroxyindole carboxylic acids and their reduced forms. When a person is exposed to the ultraviolet light (UV) from the sun, the melanocytes will produce eumelanin to prevent the skin from burning and damage to the cell nuclei (where DNA is found) of the epidermis. This melanin production causes the skin to darken. The eumelanin in the skin then acts as a natural sunscreen by blocking the damaging effects of sunlight. So, skin darkens when exposed UV light, thus providing greater protection when needed by producing more eumelanin, but it also becomes more likely to develop melanoma, which is a type of skin cancer. This is because UV rays damage the DNA of skin cells. The DNA (deoxyribonucleic acid) is the genetic material that has the instructios to the growth and functioning of an organisms). Skin cancers begin when eumelanin protection is not sufficient and this damage affects the DNA of the genes that control the growth of skin cells. This results in a tumor, which is the uncontrolled growth of cells (in this case, skin cells) because there will be a mutation in DNA that affects the function of the cells.

The following is a plot of the number of bacterial cells vs time in a culture. A culture refers to
cells grown in a man-made environment. For example, even though oceans, streams and
ponds are teaming with microbes, they are not considered a culture because they are part of a
natural environment. Yogurt as well as cells grown on agar plates or liquid cultures are
examples of a man-made environment.

define cell and atom
Answer:
Cell: All living organisms are made up of cells, which are the basic building components. Cells also carry the body's genetic material and have the ability to replicate themselves. Cells are made up of several components, each of which serves a particular purpose. Organelles, for example, are specialized structures that perform specific activities within the cell.
----------------
Atom: Protons, neutrons, and electrons are the three subatomic particles that make up an atom. The nucleus, which is made up of protons and neutrons, is at the core of the atom, while electrons float around in a tiny cloud above it.

Why do all proteins given a negative charge prior to electrophoresis?
Answer:
The principle for native gels when Coomassie is not added to the sample is that proteins are separated by a combination of size and charge. The charge in general depends on the number of amino acid residues that bear a positive or negative charge at the pH of the gel. So if running the gel at pH from 8.3 / 8.9, Asp and Glu will be negatively charged, Lys and Arg and His will be protonated and have a positive charge. The N- terminus would have a positive charge while the C terminus would have a negative charge. There might be exceptions depending upon the micro environment of each residue. Native gels can be run at acidic pH as well, to give another way of resolving proteins. Smaller proteins migrate faster than larger proteins. Also, quaternary structure is preserved, so a dimer will run as a dimer so the percentage of total acrylamide monomer used is usually lower than what is used for SDS-PAGE, e.g. 7.5% acrylamide
We can also apply the equation for residence time to a single component of a fluid, such as carbon dioxide (CO2). Assume that the residence time of CO2 in the atmosphere is six years and the mass of CO2 in the atmosphere is 3 × 1015 kilograms. If these estimates are correct, what is the mass flow rate of CO2 into and out of the atmosphere? Assume the atmosphere is at steady state. Write your answer in scientific notation, and be sure to include the correct units.
Answer:
[tex]f=5*10^1^4kg/year[/tex]
Explanation:
[tex]T=m/f\\f=m/T\\f=\frac{3*10^1^5kg}{6 years}[/tex]
The mass flow rate of CO2 into and out of the atmosphere is [tex]f = 5 * 10^{14} kg/ year[/tex]
What is the method ?
[tex]T = m/f[/tex]
Therefore, [tex]f = m/ t[/tex]
[tex]f=3 * 10^{15} / 6 years[/tex]
So, the correct answer is : [tex]f = 5 * 10^{14} kg/ year[/tex]

A degraded ecosystem is replaced with a different but productive ecosystem type, one that might even include some nonnative species. For example, a degraded forest might be replaced with a productive pasture.a. passive restoration b. remediation c. partial restoration d. rehabilitation e. complete restoration
Answer:
d. rehabilitation
Explanation:
Technology-associated rehabilitation is an ecological practice that allows a degraded area to be restored, rehabilitating all its degraded habitats. However, this restoration is not done naturally, but is caused by human intervention, which can cultivate the entire plant population in the area, even adding non-native species, which are selected to leave the productive area, but ecologically harmonious.
Elephants are considered K-strategists because they give birth to only one calf at a time and most have five years in between having another calf. Calves stay under the protection of the mother and her herd until maturity at 10-15 years of age. What type of survivorship curve do elephants tend to follow
Answer:
Type I curve
Explanation:
The K-strategist are species characterized by relatively stable populations that fluctuate at the carrying capacity of the habitat or niche in which organisms reside. Elephants are considered as K-strategists because they have a low population growth rate and relatively stable populations. There are three different types of survivorship curves. The Type I curve (also referred to as A curve) is characteristic of k-strategist organisms. Humans and elephants exhibit a Type I survivorship curve in which organisms tend to die when they become elderly. These species have a small number of offspring and provide parental care to ensure their survival. In a Type II survivorship curve, species produce many offspring and only some offspring survive (e.g., birds), while in Type III survivorship curve organisms produce many more offspring and most do not survive (i.e., r-strategists such as frogs or insects).

How does wet heat sterilization, such as an autoclave, work to inactivate bacteria and other infectious pathogens?
Answer and Explanation:
The microorganisms such as bacteria and fungi are basically composed of biological macromolecules (lipids, proteins, polysaccharides). As the temperature increases, the structure of proteins is disrupted and they lose their function. For example, enzymes that catalyze biological reactions are inactivated.
Therefore, wet heat sterilization is a process in which the material is heated during a certain time at a certain high temperature to destroy the microorganisms by producing the denaturation of structural proteins and enzymes.
Using the organisms you identified in part B, create a food web for the ecosystem you chose. Use this sample food web for reference, although your food web will contain fewer organisms. Note that your food web does not have to include images, but you may include them if you choose. However, be sure to include arrows to indicate the direction of energy flow in your food web. Design your food web using any method listed below:
Unfortunately you did not introduce the organisms identified in part B, as the question shows. This makes it impossible for me to answer this question, but I will try and help as best I can.
In the figure attached to the question below, it is possible to see an example of a food web and the arrows that indicate the direction of the energy flow within this food web.
In this sense, we can determine that a food web is the set of food chains that complete and mix. A food chain shows how living organisms organize themselves so that one feeds on the other, whereas in the food web, this food chain is shown in a more realistic way, as it shows how food chains mix and interact within the ecosystem, as they do not there are food chains isolated in nature.
