Answer:

b. Clostridium botulinum.

Explanation:

The enterotoxins (also know as exotoxins when they are produced by bacteria) are polypeptides secreted by microorganisms that target the intestine. These toxins may produce serious damage to the host by disrupting the function of the epithelial intestinal cells  Moreover, Clostridium botulinum is a Gram-positive bacterium that is able to produce a potent neurotoxin (botulinum) which is known to cause severe flaccid paralytic deformities in humans.

The organism that does NOT produce an enterotoxin among the options given is b) Clostridium botulinum. Clostridium botulinum is a bacterium known for producing botulinum toxin, which is a neurotoxin rather than an enterotoxin. It does not, however, create an enterotoxin.

The severe sickness known as botulism is brought on by the botulinum toxin, which predominantly affects the nervous system.

Although enterotoxins can induce diarrheal disorders and are linked to gastrointestinal symptoms, an organism need not produce an enterotoxin to be pathogenic. The host's sensitivity to infection and the infectious dosage are other important variables.

All of the above.

Explanation:

Proboscidea , Artiodactyla , Lagomorpha are all vegetarians and vegetarians are animals that feed on plants i.e grasses, shrubs e.t.c.

These order of animals are refered to herbivorous animals i.e animals that feed on plants and they have two pairs of growing incisors,molars and premolars.

Members of lagomorphs are rodents, hares, rabbit, pikas e.t.c.

Artiodactyla members are cattles, camels, pigs e.t.c. These order have tusks for defending themselves.

Proboscidea include elephants.

Answer:yes

Explanation:

Yes

Answer:

The molecule is a protein

Explanation:

When the molecule was tested with benedict's solution and a blue color was formed, that actually meant there was no colour change because the colour of benedict's solution is blue. Benedict's solution is used to test for the presence of reducing sugar, which changes it's colour to green, orange, yellow or even red; the fact that there was no colour change shows the molecule is not a reducing sugar.

Yellow colour when tested with IKI (Iodine-potassium iodide) also shows no colour change. IKI reagent is used to determine the presence of starch, which gives off a dark-blue colour if starch is present. Hence, absence of this dark-blue colour or observation of a yellow/orange colour shows the molecules is not starch.

Biuret reagent is used to test for peptide bonds in a molecule. In the presence of a peptide bond, the biuret reagent changes colour from blue to violet. The amino acids in proteins are held together by peptide bond, hence the biuret colour change shows that the biomolecule is a protein.

Answer:

Mean is the average you'll get when you add all your numbers then divide by the number of numbers you have. On the opposite side, median is the middle number within your list of numbers. If there isn't a middle number, take the two middle numbers and add them. Now, for how they are alike, I'm not so sure :'), but my closest guess would be they are fairly close together.

Answer:

It would be impossible to store and transfer genetic information

It would be impossible to carry out majority of cellular activities due to lack of usable energy.

Explanation:

Phosphorus, as stated in the question, represents a very low amount in our body system, however, its role in living systems cannot be underestimated. Phosphorus is a vital component of major biomolecules in our system.

- It is the building block of the NUCLEOTIDES that make up nucleic acids. Nucleic acids (DNA and RNA) store genetic information and help transfer it to offsprings. However, without one of the elemental components (phosphorus) that make up its structure, it will not be produced. Hence, the storage and transfer of genetic information will be impossible.

- Phosphorus also makes up the structure of the ADENOSINE TRIPHOSPHATE (ATP) molecule. ATP provides the cell with all the energy used in carrying out cellular functions. However, the absence of phosphorus needed for the synthesis of ATP, ATP will not be produced and ultimately no energy.

The two divisions of the autonomic nervous system are the sympathetic and parasympathetic nervous systems. The correct option is C. sympathetic and parasympathetic nervous systems.

From the question, we are to determine the two divisions of the autonomic nervous system.

The nervous system is divided into two main parts, which are

The central nervous system is made up of the brain and the spinal cord, while the peripheral nervous system is made up of the nerves and ganglia that lie outside of the brain and spinal cord.

The peripheral nervous system is further subdivided into the somatic nervous system and the autonomic nervous system.

The autonomic nervous system is further divided into the sypathetic nervous system and the parasympathetic nervous system.

The sympathetic nervous system is for fight or flight responses, and

The parasympathetic nervous system is for rest and digest responses.

Hence, the two divisions of the autonomic nervous system are the sympathetic and parasympathetic nervous systems. The correct option is C. sympathetic and parasympathetic nervous systems.

Answer:

B. The 55 N cat has less mass than the 110 N dog.

Explanation:

Weight of an object refers to the product of its mass and the force of gravity. However, the greater that mass of an object, the greater the weight of that object.

In this case, the cat's weight is 55N while the dog's weight is 110N. This means that the dog has a greater mass than the cat or alternatively put, the 55 N cat has less mass than the 110 N dog.

Note that: if the gravitational effect is removed, the cat will contain lesser mass.

a. Make antibodies

Explanation:

B-cells is one of the two types of lymphocytes or white blood cells produced in the marrow of the bone (the other being T-cells). B-cells are a part of adaptive or acquired immunity in our body i.e. a learned defense after a pathogen might have penetrated.

B-cells help combat foreign Invaders that make way into the body by producing ANTIBODIES, which are specific to a particular pathogen. Note that, the B-cells learnt to combat based on a previous infection of such pathogen. In response to an antigen, the B-cells produce the plasma cells, which in turn produce the antibodies.

Answer:

Asexual Reproduction

Explanation:

As the bacteria cell is dividing on its own to create more bacteria, it is performing asexual reproduction as it is not reproducing with a secondary bacteria cell.

Asexual reproduction is the process by which a bacteria cell that divides to create two exact copies of itself.  Thus option C is correct.

Bacteria reproduce by the process of asexual reproduction which is mainly binary fission, where the offspring produced from parent are  similar.

In this process parent cell is undergo division and separated into two new daughter cells. Each daughter cell get one copy of its parent DNA.

No spindle apparatus formation occur in binary Fission. In this process, the DNA molecule undergo replication and attaches each copy to various parts of the cell membrane

For example, Prokaryotes like  E. coli, Archaea and some eukaryotes like euglena reproduce through binary fission.

The advantage of binary fission is very fast and it requires single organism or parent.

Thus option C is correct.
