Answer:
A sustainable system refers to producing less or probably non-existent debris that are caused by the production of a particular material (i.e. produce, energy). This is a sustainable form of production of coupling algae growth and fish farming because you no longer need the supply of fish feed from other sources that are made artificially but rather, you are using the available algae growth that you are culturing. Farm fishing alone is non-renewable because this produces much waste that can directly harm the environment.
An integrated aquaculture system of fish farming with kelp farming is a sustainable system as both system exchange resources and thus reduce wastage of resources.
What is an integrated aquaculture system?An integrated aquaculture system is an aquaculture system which combines several forms of aquaculture together.
For example, kelp farming is a form of aquaculture which can be integrated with another form of aquaculture such as fish farming.
Integrating fish farming with kelp farming is a sustainable system as both system provides what the other needs.
The kelps serve as food to fish while fish waste serve as manure for kelps.
Therefore, integrating fish farming and kelp farming is a form of a sustainable system.

Explanation:
it is the answer.
One moth population carries three alleles at a genetic locus: X1, X2and X3. X1is dominant to X2and X3; X1produces red antennae. X2is co-dominant to X3; X2X2produces yellow antennae, X3X3produces white antennae, and X2X3produces light yellow antennae. The phenotypes in a population are as follows: 0.04 white; 0.16 light yellow; 0.16 yellow; 0.64 red.Assuming that this population is in Hardy-Weinberg equilibrium, what is the frequency of the X3allele in this population
Answer:
The correct answer is - 0.20
Explanation:
According to Hardy Weinberg equation under specific conditions the frequencies of the allele in the gene in a given population remain constant. Thus according to this frequencies of allele and genotype will remain the same through the generation unless there will be no evolutionary influence.
It helps us to predict the genotype frequencies in a large population. If there are two alleles having allelic frequencies p and q and we know equation of probability and frequencies add to 1
p2+2pq+q2=1
The X3X3 genome produces white antennae. Now Phenotypic frequency of the white antennae is 0.16 or 0.04 in the whole population. Hence the frequency of X3 should be a square root of 0.04 i.e, 0.20.

In water and ice, the slightly ______ hydrogen atoms in one water molecule are drawn to the slightly _______ oxygen atom in another water molecule.
A. positive, negative
B. negative, positive
C. neutral, positive
D. neutral, negative
Answer:
option c
Explanation:
The water molecule is a polar substance that has partially charged ions. The hydrogen atom is partially positive, whereas the oxygen atom is partially negative in charge. Thus, option A is correct.
What is polarity?The polarity of the molecule is defined by the presence of the electrical charges over the elemental atom that results in the formation of the chemical bonds by the electrostatic forces.
Water is an example of a polar molecule that is linked by a covalent bond by sharing the electrons between the oxygen and the hydrogen atom of the molecule.
The hydrogen atom is said to have a partial positive charge and oxygen has a partial negative charge because of the uneven electron density. The electronegative oxygen pulls the hydrogen towards it.
Therefore, option A. hydrogen is partially positive and oxygen is partially negative.

Question 3
Some globular proteins are water soluble, while all fibrous/membrane proteins are water insoluble.
Which of the following statements BEST explains the reason for these differences?
A
Fibrous proteins have a large number of hydrogen bonds between the amino acids in the polypeptide chains that stabilize their structures, preventing solubility in water. The globular proteins that are water-soluble do not have as many hydrogen bonds between the amino acids in their peptide chains, allowing water solubility.
B
Fibrous proteins are configured in a way that exposes the polar side chains of the amino acids on the surface of the protein, preventing solubility in water. The globular proteins that are water soluble have nonpolar side chains on the surface of the protein, allowing water solubility.
C
Some globular proteins are configured in a way that exposes the polar groups of the amino acids on the surface of the protein, allowing water solubility. Fibrous proteins have nonpolar side chains on the surface of the protein, preventing water solubility.
D
Some globular proteins are composed of more than one polypeptide chain that weakly interacts with one another, allowing water solubility. Fibrous proteins are composed of only one polypeptide chain that tightly folds, preventing water solubility.
Globular proteins are spherical proteins which are water soluble and forms colloid in water.
The best statement which will explain the reason for difference in globular protein and fibrous proteins is statement C.
C. Some globular proteins are configured in a way that exposes the polar groups of the amino acids in the surface of the protein, allowing water solubility.
Fibrous proteins have non polar side chains on the surface of the proteins, preventing water solubility.

una persona camina durante una hora y media y corre 4 km con velocidad constante ¿cuál era su velocidad en km/h y en m/s?
La respuesta es: su velocidad es 2.66 km/h, equivalente a 0.738 m/s.
Explanation
Para conocer la velocidad de una persona que recorrió 4 km luego de caminar durante una hora y media es necesario dividir la distancia (en kilómetros) total en el tiempo (en horas). Entonces la operación sería:
4km/1,5h = 2.66 km/h.
Posteriormente, para convertir 2.66 km/h en m/s es necesario aplicar la siguiente formula
2.66 km/h *(1000 m/1 km)*(1 h/3.600 s) = 0.738 m/s.

What does the word Photosynthesis mean?
A. Release of energy through the breakdown of Glucose.
B. Creating photographs.
C. Taking apart with light.
D. Putting together with light.
Answer:
A
Explanation:
release of energy through the breakdown of glucose
The release of energy through the breakdown of Glucose means Photosynthesis.
PhotosynthesisPhotosynthesis is a process used by plants and other organisms to convert light energy into chemical energy that, through cellular respiration, can later be released to fuel the organism's activities. Some of this chemical energy is stored in carbohydrate molecules, such as sugars and starches, which are synthesized from carbon dioxide and water – hence the name photosynthesis, from the Greek phōs "light", and synthesis "putting together" Most plants, algae, and cyanobacteria perform photosynthesis; such organisms are called photoautotrophs. Photosynthesis is largely responsible for producing and maintaining the oxygen content of the Earth's atmosphere and supplies most of the energy necessary for life on Earth.
Although photosynthesis is performed differently by different species, the process always begins when energy from light is absorbed by proteins called reaction centers that contain green chlorophyll (and other colored) pigments/chromophores. In plants, these proteins are held inside organelles called chloroplasts, which are most abundant in leaf cells, while in bacteria they are embedded in the plasma membrane. In these light-dependent reactions, some energy is used to strip electrons from suitable substances, such as water, producing oxygen gas.

A tech is using the H (flagellar) antigen to serotype a suspected Salmonella species. The results of the serotyping are agglutination with one well that indicates a group of possible serotypes, not one particular serotype. Quality control passed. Why did this occur
Some Salmonella H antigens can occur in multiple strains and serotypes
An antigen (Ag) is any molecule/structure such as, for example, a molecule present on the surface of a pathogenic microorganism, that can be bound by a specific antibody and/or B-cell receptor. The Kauffmann–White classification scheme is a system that was adopted for use in 1934 in order to categorize different serotypes of the bacterial genus Salmonella, based on their somatic-surface antigens. The system is a practical (diagnostic) method based on the variation in the somatic (O) and flagellar (H) antigens present in the cell wall of Salmonella species. In this classification system, 'O' antigens are determined based on oligosaccharides which are associated with lipopolysaccharide, while the "H" antigens are distinguished by the protein content of the Salmonella flagella.Learn more about this topic here:

Identy three advantages and three disadvantages of bioplastics
Explanation:
Advantages of bioplastics
1.Less oil is used to produce petrochemical (oil-based) plastics which pose a great risk to the environment.
2.The common bioplastics can be injection molded and shaped to take the same form as traditional thermoplastics. In some cases, the bioplastics are stronger and lighter, too, so they are not necessarily only suitable for very niche applications.
3.Bioplastics are more marketable, for example, their usage may improve the value-add of a product through a green marketing campaign. After all, studies have shown that ‘80% of European customers want to buy products with a minimal impact on the environment,’ so bioplastics may represent a useful argument for brands.
Disadvantages of bioplastics
1.First, bioplastics are generally NOT cost-competitive compared to their oil-based counterparts. They are generally two or three times more expensive than the major conventional plastics such as PE or PET, and their production is plagued by low yields and being expensive. This disadvantage should be less acute when manufacturing plants become larger and benefit from economies of scale. A good example is Braskem’s 200,000-tonne bio polyethylene plant (equivalent to about 20% of the world’s current bioplastics production).
2.There is a concern that bioplastics based on terrestrial crops could harm food supplies; however, new innovations using food waste could be helpful in this regard and the concerns would seem to be unfounded as: ‘Perhaps 300,000 hectares are used to grow the crops which the industry processes into plastics. For comparison, this is about 0.02% of the world’s total naturally irrigated area available for cultivation. Even if half the world’s plastics were made from crops grown on food land, the industry would only require 3% of the world’s cultivated acreage.’
3.Crop-based bioplastics require fertile land, water, fertilizers, and are reliant on weather conditions. This means that the supply of raw materials for bioplastics are at risk of natural phenomena, such as drought.
Answer:
Three advantages of bioplastics:
1. Saving fossil fule
2. Reduction of greenhouse gas emission
3. Reclamation of by-products
Three disadvantages of bioplastics:
1. It won't biodegrade in a landfill
2. It contaminate plastic recycling streams
3. It encourage people to litter more

Approximately how many mutations occur naturally in DNA per 10,000 bases?
A. 2
B. 2000
C. 200
D. 20
Explanation:
Modern methods indicate that the mutation rate is roughly one to two mutation per 10,000 genes per generation.
In human cells, approximately TWO (2) MUTATIONS occur naturally in DNA per 10,000 bases (Option A is correct).
The mutation rate (u) refers to the occurrence of new mutations in a given nucleotide sequence over time.In human cells, the mutation rate is approximately 10⁻⁴ per generation.Therefore, in a DNA sequence that has 10,000 base pairs of length, this value is equal to 2 mutations per generation (u = 2 / 10,000 = 10⁻⁴).In conclusion, approximately 2 MUTATIONS occur naturally in DNA per 10,000 bases (Option A is correct).
