Answer: A plant cell contains a large, singular vacuole that is used for storage and maintaining the shape of the cell. In contrast, animal cells have many, smaller vacuoles. Plant cells have a cell wall, as well as a cell membrane. Animal cells simply have a cell membrane, but no cell wall.

Distinguish between an acid and alkaline slant?
Answer:
Acid slant: yellow, fermentation of glucose and lactose and/or sucrose. High concentration creates excessive acid formation
Alkaline slant: red, limited glucose in the medium and limited acid formation.
The pH of acids is less than 7. Alkalis have a pH more than 7 The pH of neutral substances is 7. If metal oxides are soluble in water, they are alkaline. Non-metal oxides are acidic, if soluble in water.
What are acids?An acid is a molecule or ion that can either donate a proton (Bronsted-Lowry acid) or form a covalent bond with an electron pair (Lewis acid). The proton donors, also known as Bronsted-Lowry acids, are the first type of acid.
Only dextrose fermentation produces an alkaline/acid (red slant/yellow butt) reaction.
The fermentation of dextrose, lactose, and/or sucrose is indicated by an acid/acid (yellow slant/yellow butt) reaction.
An alkaline/alkaline reaction occurs when as a result, carbohydrate fermentation does not occur.
The presence of red (alkaline) in the slant and butt indicates that the organism being tested is a nonfermenter.
The formation of hydrogen sulfide results in a black precipitate in the butt of the tube. The splitting and cracking of the medium indicates gas production.
Thus, these are the basic difference between acid and alkaline slant.

hiw has human trafficking displayed itself in communities.
Explanation:
Human trafficking is causing a serious threat.It is the trade of humans,most commonly for the purpose of sexual slavery,forced labour or commercial sexual exploitation for the trafficker or others.The business is started with foreign employment,marriage,travelling to beautiful cities etc and such illiterate and poor people are lured by them.Thus,it has displaced a negative impact and a questioning glance to the people about human kind and humanity.
Leucine biosynthesis occurs in a multistep pathway starting from 2-oxovalerate, and the final product of the pathway (leucine) inhibits the first enzyme involved in the biosynthetic pathway through a process called feedback inhibition. This enzyme inhibition occurs, regardless of whether or not the 2-oxovalerate substrate is bound in the active site of the enzyme. Describe what type of inhibitor leucine is and justify your response.
Answer:
it is a type of mixed inhibition referred to as 'non-competitive inhibition'
Explanation:
Mixed inhibition occurs when an inhibitor binds to the enzyme in a site different from the active site where the substrate binds (i.e., the allosteric site). The term 'mixed' is because this inhibition is a mixture of competitive inhibition, where the inhibitor competes with a substrate to bind to the enzyme, and uncompetitive inhibition, where the inhibitor binds only to the complex formed between the enzyme and its substrate. In competitive inhibition, the maximal velocity of the reaction (Vmax) does not change, whereas the apparent Km (i.e., the concentration of substrate which permits the enzyme to achieve half Vmax) increases. Moreover, in non-competitive inhibition, the Km does not change, whereas the Vmax decreases. Non-competitive inhibition is a special type of mixed inhibition where the apparent Vmax (V app-max) is reduced, while the Km of the enzyme is unaffected.
Cilia are involved in the transfer The genetic information from one bacterial cell to another
Answer:
False.
Explanation:
No, Cilia are not involved in the transfer of the genetic material from one bacterial cell to another. The pili are the structure which is responsible for the transfer of genetic material from one bacteria to another. This transfer can only occur for those types of bacteria that possess a special plasmid that is responsible for the formation of pilus which leads to the transfer of genetic material. If the special plasmid is not present so there will be no tranfer of genetic material from one bacteria to another.

1. Would the pollution problems caused by cars and trucks be completely solved if they all became electrically powered overnight?
2. Name one challenge we need to overcome by using solar panels
Answer:
1.This doesn't help COMPLETELY get rid of pollution. It might help lessen the pollution, but it definitely won't solve it, because there are also other things that cause pollution.
2.The main problem with solar power that has stifled its use is the fact that energy production only takes place when the sun is shining. And it won't be beneficial to the countries that aren't really close to the equator ( the middle east) and that might be a problem cause there just might not be enough energy/electricity.

At rest the lens of the eye will be more round when the ciliary muscles are contracted true or false
Answer:
True.
Explanation:
Yes, the lens of the eye will be more spherical when the ciliary muscles are contracted due to tension. When the relaxation occurs in the ciliary muscle , the zonular tension is increased, that causes the lens to be flatten and leads to decrease in optical power while on the other hand, when the ciliary muscle contracts, the tension in the equatorial zonular is increased which causes the central lens surface to become more rounded that leads to increases central optical power.

6. Samples of atmospheric air and exhaled air were analysed by four groups
of students for oxygen and carbon (IV) oxide content. The following are
the results, expressed in volumes per thousand:
(i) Amount of oxygen in atmosphere = 200
(ii) Amount of oxygen in exhaled air = 160
(iii) Amount of carbon (IV) oxide in atmosphere = 300
(iv) Amount of carbon (IV) oxide in exhaled air =41
Explain the difference in volume of each gas between the atmosphere and
the exhaled air.
Answer:
Due to difference in volume of both atmosphere.
Explanation:
There is difference in volume of carbondioxide and oxygen gas between the atmosphere and the exhaled air because of the volume difference of atmosphere and exhaled air. The volume of atmosphere is larger than the body from where the gases are exhaled. The body has lower space for these gases so these gases are less in concentration in the exhaled air which the body releases as compared to the atmosphere where the concentration of these gases are larger.
Generate a random protein sequence that is 5 amino acids long.
Answer:
Random protein sequence 5 amino acids long
LYSINE - GLUTAMINE - VALINE - GLYCINE - LEUCINE
Explanation:
Proteins are macronutriens formed by amino acids. Amino acids are the monomers of proteins, meaning they are the structural units. These organic compounds are made of amino and carboxyl groups.
For every amino acid there is a DNA sequence:
Lysine: AAA
Glutamine: CAA
Valine: GTG
Glycine: CCC
Leucine: AAT
This protein sequence of 5 amino acids long would be like this in its DNA:
AAA CAA GTG CCC AAT
