Answer:
C. They have a greater surface-to-volume ratio.
Explanation:
Because these smaller cells can access and pass through the membranes of the other cell membranes and permeable coverings easily and voluntarily unlike larger cells. It is also efficient for these smaller cells to penetrate and travel, delivering and transporting goods and materials such as nutrients, oxygen and waste throughout the body without consuming enough energy and conserving lesser space.
For simple reasons, they are faster, more efficient and consumes little space, and most especially depletes lesser energy. So, many small cells have more surface area than one large cell.

why is the product MILO not a suitable for a vegan diet
MILO and MILO products may not be suitable for a vegan diet due to:
MILO and its products consist mainly of cocoa, malt barley, sugar, and milk powder. Milk powder essentially comes from animals.A vegan is a person whose lifestyles exclude animal products, especially when it comes to diets. A vegan diet primarily consists of plant and plant products.Hence, the fact that MILO consists of powder milk which is animal-based might make it unsuitable for a vegan diet.
More about vegan diets here: https://brainly.com/question/16160533
Answer:
Explanation:
VEGAN DIET
A Vegan diet refers to diet that contain food from plants such as maize , beans, rice, wheat e.t.c It is mainly plants source and does not contain animal source.
But MILO is also Plant based energy and it contains several vitamins and minerals to help grow a healthy body: It contain Vitamins B2 and B3 which help to support effecient energy release in the body. It contain Essential nutrients like iron, zinc which are very minute
in plant based diets. Milo contain milk which is of animal source.
Therefore, Milo product is not suitable for a vegan diet because it contains milk solids which is derive from animal source.

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:

what do you mean by bacteria?
Answer:
Bacteria is a type of micro-organism and is also a prokaryote. These organisms can only be seen using a microscope. Some bacterias are harmful while some are helpful for human daily lives, such as probiotics, and are necessary for life. They have simple cell structures as there is no nucleus or membrane-bound organelles. Bacterias can be found in soil, water, plants, animals, etc. They can cause diseases such as Tuberculosis etc. Due to some diseases being caused by bacterias, doctors prescribe Antibiotics which has the ability to stop the activities in bacterial cell that causes it to lose its protective outer covering and completely stops it from multiplying.
Answer:
Bacteria are among the smallest living things. A single bacterium consists of just one cell, and is called a single-celled, or unicellular organism.
Even though it is just a single cell, it can carry out all seven life processes (movement, respiration, sensitivity, growth, reproduction, excretion and nutrition).

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

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.
Globular proteins are water soluble. Fibrous proteins are not soluble in water.
Amino acids chain prevents folding up so that the chain is not broken and it remains in elongated form. The correct answer is C.
