The statement which is based on Schleiden's work is that the cell is the smallest functional unit of life.

The scientific idea that cells make up living organisms, that they are the fundamental structural and organizational unit of all organisms, and that they all originate from previously existing cells is known as cell theory. It was first proposed in the middle of the nineteenth century. All organisms' fundamental structural and reproductive building blocks are called cells.

The cell theory's three pillars are as follows:

The basic and structural component of existence is the cell. Cell biology is the study of cells, including their fundamental makeup and each organelle's functions. Cells were first discovered by a biologist, Robert Hooke. Cells comprise all living things. They could consist of many cells  (multicellular) or just one (unicellular). The foundation of all living things are cells. They give the body structure and transform the food's nutrients into energy.

Complex cells have many parts that each serve a different purpose within a body. Similar to construction bricks, they come in a variety of sizes and shapes.

In the given question, the statements given to us are,

A. Plants are made of different specialized cells.

B. All animals are made of cells.

C. All cells have developed from preexisting cells.

Fragmentation is a form of asexual reproduction and is seen in annelids, fungi, cyanobacteria, sponges, and flatworms.

In Fragmentation, an organism divides itself into a number of fragments. It occurs when an organism completely breaks down independently irrespective of the other parts. Each one of these fragments matures into fully grown adults that are clones of the original organism.

Asexual reproduction usually involves the participation of a single parent alone can produce new offspring. The newly produced individual is genetically identical to one another and its parent. Both multicellular and unicellular organisms divide by fragmentation which is asexual reproduction.

Fragmentation is the most common method of reproduction in lower invertebrates. It is seen in many organisms including filamentous cyanobacteria, algae, lichens, molds, many plants, and animals such as flatworms,  annelid worms, sponges, and sea stars.

The organisms that can reproduce by fragmentation are Option d Sponges and Sea anemones.

Fragmentation is a form of asexual reproduction in which an organism breaks into two or more fragments, and each fragment develops into a new individual. Both sponges and sea anemones are examples of organisms that exhibit this mode of reproduction.

Sponges are simple multicellular animals that lack true tissues and organs. They possess a porous body structure, and when a sponge is fragmented, each fragment has the potential to develop into a new sponge through regeneration. These fragments contain specialized cells called archaeocytes that can differentiate into various cell types required for the formation of a new sponge.

Sea anemones, on the other hand, are marine animals belonging to the phylum Cnidaria. They have a cylindrical body with tentacles surrounding their mouth. When a sea anemone is fragmented, each piece can regenerate into a complete individual. The process involves the differentiation of cells within the fragments, leading to the development of new tentacles, body parts, and eventually a mature sea anemone.

Both sponges and sea anemones have remarkable regenerative abilities, allowing them to reproduce through fragmentation. This form of asexual reproduction enables them to colonize new areas, expand their population, and adapt to changing environmental conditions. Therefore the correct option is D

Answer: the cfu/g Gram-negative bacteria in the fecal sample is C = 3.0 × 10^3

Explanation:

We know that; Gram negative bacteria looks  pale reddish in color under a light microscope from Gram staining.

therefore

There are 30 red bacterial colonies counted.

1 mL of from tube 1 was removed and added to tube with 99 mL saline (tube 2) dilution is 1/100.

transferred volume  into the plate is 1 mL.

Now, we have to determine the cfu/g Gram-negative bacteria in the fecal sample

Formula to calculate CFU/g bacteria in fecal sample is expressed as;

C = n/(s×d )

where C is concentration (CFU/g) , n is number of colonies , s is volume transferred to plate , d is dilution factor.

so we substitute

C = 30 / ((1/100) × 1)

C = 30 / 0.01

C = 3000

C = 3.0 × 10^3

THERFERE, the cfu/g Gram-negative bacteria in the fecal sample is C = 3.0 × 10^3

The doubling time for South Sudan with a growth rate of 2.82% is approximately 24.82 years. The answer is option B.

The doubling time formula is given by:

Doubling time = 70 / growth rate

Given that the growth rate of South Sudan is 2.82%, we can substitute it into the formula to get:

Doubling time = 70 / 2.82

Using a calculator, we can evaluate this expression to get:

Doubling time ≈ 24.82 years

Therefore, the doubling time for South Sudan with a growth rate of 2.82% is approximately 24.82 years. The answer is option B.

Doubling time is a term used in many disciplines, including biology, economics, and finance, to define how long it takes for a quantity to double in size or value.

In its most basic version, doubling time refers to the amount of time it takes to double the size of a population, investment, or any other quantity, presuming a constant rate of growth or increase.

For example, if a bacterial population doubles in size every hour, the doubling period is one hour.

Varicella Zoster is an infectious viral disease causing chickenpox in children and shingles in grown-ups. Inoculation plays a crucial part in avoidance and lessening complications.

Women and noblemen,

Nowadays, I would like to examine a vital and predominant viral disease known as Varicella Zoster. Varicella Zoster, commonly alluded to as chickenpox, is caused by a varicella-zoster infection. It fundamentally influences children, but can too affect grown-ups who have not been already contaminated.

Varicella Zoster presents as a profoundly infectious sickness characterized by a particular hasty, fever, and common disquietude. The infection spreads through coordinated contact or respiratory beads, making it effortlessly transmissible inside families and communities.

Whereas chickenpox is for the most part a gentle ailment in children, it can lead to more serious complications in grown-ups, pregnant ladies, and people with debilitated resistant frameworks. These complications incorporate pneumonia, bacterial contaminations, and in uncommon cases, neurological complications such as encephalitis.

Luckily, the improvement of a profoundly successful antibody has essentially diminished the frequency of Varicella Zoster around the world. Immunization not as it were secures people from the distress and potential complications of chickenpox, but too makes a difference anticipate the infection from spreading inside the community.

In any case, Varicella Zoster doesn't halt at chickenpox. Once the introductory contamination settles, the infection remains torpid inside the body and can reactivate a long time afterward, causing a condition known as herpes zoster, or more commonly, shingles.

Shingles are characterized by a difficult hasty that ordinarily happens in a single dermatome, regularly along the middle or confront. The reactivated infection can cause critical pain and inconvenience, enduring for weeks or indeed months. Moreover, complications such as postherpetic neuralgia, a persistent torment disorder, can happen, especially in more seasoned people.

To combat the chance of shingles, an isolated antibody called the shingles antibody or herpes zoster immunization has been created. This antibody not as it were makes a difference anticipate shingles but moreover diminishes the chance of postherpetic neuralgia.

In conclusion, Varicella Zoster, enveloping both chickenpox and shingles, could be a viral contamination that has critical suggestions for open well-being. We have made significant progress in reducing the burden of this disease through extensive vaccination efforts.

In any case, ongoing efforts to prevent Varicella zoster from returning to our communities and to protect powerless populations require prompt attention and vaccination.

Plasma membranes must permit some compounds to enter and exit a cell while blocking the entry of hazardous molecules and the exit of necessary ones.

In other words, plasma membranes selectively permit some compounds to pass through while blocking others. The cell would be destroyed if it were to lose its selectivity, which would prevent it from continuing to function.

Certain compounds are needed by some cells in greater concentrations than by other cells; these cells must have a method of acquiring these substances from the extracellular fluids.

The movement of specific materials back and forth may cause this to occur passively, or the cell may have unique processes to assure transit. Adenosine triphosphate (ATP) is the primary kind of energy.
