In 1839, Schleiden and Schwann began formulating a theory of cells and their role in living organisms. Over time, cell theory has been updated. Modern cell theory is summarized below.
Answers
Answer: The modern cell theory are in following ways:-
(1) All known living things are made up of one or more cells.
(2) All living cells arise from pre-existing cells by division.
(3) The cell is the fundamental unit of structure and function in all living organisms.
(4) The activity of an organism depends on the total activity of independent cells.
(5) Energy flow (metabolism and biochemistry) occurs within cells.
(6) Cells contain DNA which is found specifically in the chromosome and RNA found in the cell nucleus and cytoplasm.
(7) All cells are basically the same in chemical composition in organisms of similar species.

Answer:
Characteristics of living things
There are seven activities which make organisms different from
non-living things. These are the seven characteristics of living
organisms.
1 Nutrition
Living things take in materials from their surroundings that they
use for growth or to provide energy. Nutrition is the process by
which organisms obtain energy and raw materials from nutrients
such as proteins, carbohydrates and fats.
2 Respiration
Respiration is the release of energy from food substances in all
living cells. Living things break down food within their cells to
release energy for carrying out the following processes.
3 Movement
All living things move. It is very obvious that a leopard moves but
what about the thorn tree it sits in? Plants too move in various
different ways. The movement may be so slow that it is very
difficult to see.
4 Excretion
All living things excrete. As a result of the many chemical
reactions occurring in cells, they have to get rid of waste products
which might poison the cells. Excretion is defined as the removal of
toxic materials, the waste products of metabolism and substances
in excess from the body of an organism.
5 Growth
Growth is seen in all living things. It involves using food to
produce new cells. The permanent increase in cell number and size
is called growth.
6 Reproduction
All living organisms have the ability to produce offspring.
7 Sensitivity
All living things are able to sense and respond to stimuli around
them such as light, temperature, water, gravity and chemical
substances.
Learn these seven characteristics of living organisms. They form
the basis of the study of Biology. Each one of these characteristics
will be studied in detail during the course. Whilst many other
things carry out one or more of the above processes, only living
organisms possess all of these characteristics.

The cooperative breeding system of primates such as marmosets and tamarins can be explained by____ a) chimerism, which increases fraternal twins' inclusive fitness when they help raise one another's offspring. b) helpers who care for the offspring of the breeding pair, although the helpers are usually not related to them. c) the fact that mothers sometimes allow their daughters to breed. d) mutualism between the nonbreeding helpers.
Answers
The cooperative breeding system of primates such as marmosets and tamarins can be explained by chimerism, which increases fraternal twins' inclusive fitness when they help raise one another's offspring.
Cooperative breeding in primates like marmosets and tamarins is primarily driven by chimerism (option a). In these species, fraternal twins share blood supply in the womb, leading to the exchange of cells and creating chimeric individuals. This chimerism increases their inclusive fitness, as helping their twin raise offspring also benefits their own genetic material.
The other options (b, c, and d) may contribute to cooperative breeding to some extent, but chimerism plays a crucial role in enhancing the twins' inclusive fitness, making it the most significant factor in explaining the cooperative breeding system observed in these primates.

What is the characteristic feature of the cell wall of gram-positive bacteria?
Answers
The characteristic feature of the cell wall of gram-positive bacteria is the presence of a thick layer of peptidoglycan that is held together by teichoic acids.
This layer of peptidoglycan is responsible for providing structural support and protection to the cell, as well as contributing to its ability to retain the crystal violet stain during the gram staining process. Additionally, the cell wall of gram-positive bacteria lacks an outer membrane, which is found in gram-negative bacteria, and makes them more susceptible to certain antibiotics.
The peptidoglycan retains the crystal violet dye during the Gram staining process, giving gram-positive bacteria a purple appearance under a microscope.
Additionally, gram-positive bacteria typically lack an outer membrane and have teichoic acids embedded in the cell wall structure.

How finance and social changes might contribute to a rise to one's stress level as you move from school to a higher education institution?
Answers
The transition from school to a higher education institution can lead to increased stress levels due to financial pressures and social changes.
The shift from school to a higher education institution brings about several factors that can contribute to heightened stress levels. Firstly, financial concerns play a significant role. Many students face the burden of tuition fees, accommodation expenses, and the need to cover daily living costs. The financial strain can lead to anxiety and worry about meeting these financial obligations, potentially affecting a student's overall well-being.
Additionally, social changes during this transition can also contribute to allostatic load. Moving from a familiar school environment to a larger, more diverse institution can be overwhelming. Students may face challenges in building new social networks, adjusting to different social dynamics, and feeling a sense of belonging. These social pressures can lead to feelings of isolation, loneliness, and a sense of being out of place.

T/F the absence of chemical residues always rules out the possibility of arson
Answers
The statement ' the absence of chemical residues always rules out the possibility of arson' is false as chemical residues may contain arson.
While the presence of certain chemical residues, such as accelerants like gasoline or kerosene, can be a strong indicator of arson, their absence does not definitively rule out the possibility of arson.
Other factors, such as burn patterns, multiple points of origin, and eyewitness accounts, can also provide evidence of arson. Therefore, a thorough investigation involving multiple lines of evidence is necessary to determine the cause of a fire.
While the presence of chemical residues such as accelerants can provide strong evidence of arson, their absence does not necessarily rule it out.
There are several reasons why accelerants may not be found, including the use of a low-odor or slow-burning accelerant that does not leave behind significant residues, the complete combustion of the accelerant like arson during the fire, or the loss of the accelerant due to evaporation or soaking into porous materials before samples can be collected.

Answer:
35% thymine, 15% guanine and 15% cytosine
Explanation:
35% thymine, 15% guanine, and, 15% cytosine because the exact same amount of thymine would pair up with adenine, thus thymine has to be 35%. Thymine and adenine take up 70% of the DNA the rest has to equal 30%. Guanine and cytosine make up the rest, which is 30%, thus we have to split it evenly because they pair up with each other. Therefore, guanine and cytosine equal 15%.

What harmful effects does farming have on the environment?Large-scale conventional farming is heavily reliant on fossil fuels, herbicides, antibiotics, and synthetic fertilisers and emphasises intensive single crop production. While this method produces a lot of goods, it also adds to global warming, pollutes the air and water, and reduces soil fertility.Topsoil can dry out as agricultural fields take the place of natural vegetation. It is possible for nutrients to wash out and for the diversity and number of microorganisms that maintain the soil fertile to decline.

which finding in a urinalysis would indicate the presence of a urinary tract infection?
Answers
The finding in a urinalysis that would indicate the presence of a urinary tract infection (UTI) is the presence of abnormal levels of white blood cells (leukocytes) and bacteria in the urine.
During a UTI, bacteria, typically from the gastrointestinal tract, enter the urinary system and colonize the urethra, bladder, or other parts of the urinary tract. As a response to the infection, the body's immune system mobilizes white blood cells to fight off the invading bacteria.
In a urinalysis, elevated levels of leukocytes (leukocyte esterase) are indicative of inflammation and suggest the presence of an infection. Additionally, the presence of bacteria (bacteriuria) in the urine confirms the likelihood of a urinary tract infection.

A urinary tract infection (UTI) in a urinalysis can be indicated by the presence of leukocytes, the detection of leukocyte esterase, the discovery of nitrites, and the existence of red and white blood cells and bacteria in a urine culture.
Explanation:In a urinalysis, several findings could potentially indicate the presence of a urinary tract infection (UTI). Typically, these include the presence of leukocytes, specifically the detection of leukocyte esterase which is released by these cells. This is viewed as indirect evidence of a urinary tract infection. Also, the discovery of nitrites can signal an active bacterial infection, as certain bacteria like E. coli and K. pneumoniae convert nitrate to nitrite. Lastly, a urine culture identifying the existence of red and white blood cells and bacteria can provide factual evidence of a UTI.
Furthermore, a urine culture following positive Leukocyte esterase or nitrite results could be used to conclusively ascertain the presence of a bladder infection. Symptoms of UTIs can include high fever, abdominal pain, and bloody urine.

Answers
Bacteria play a critical role in the cycling of carbon, nitrogen, and phosphorus in the environment. In the carbon cycle, bacteria help to decompose organic matter and release carbon dioxide back into the atmosphere, which can be used by plants for photosynthesis. In the nitrogen cycle, bacteria convert atmospheric nitrogen into a form that plants can use, and also help to convert nitrogen back into a gas that can be released into the atmosphere. Finally, in the phosphorus cycle, bacteria help to break down organic matter and release phosphorus into the soil, which can be taken up by plants. Without bacteria, these nutrient cycles would be disrupted, which could have significant impacts on ecosystems and the global climate.
What is bacteria?Bacteria are single-celled microorganisms that are found in nearly every environment on Earth, from soil to water to the human body. They are some of the smallest and most abundant organisms on the planet, and can take a variety of shapes, including spheres, rods, and spirals.
