Answer:
It means the way genes are expressed is the same in most organisms.
Explanation:
All living organisms use the same DNA or RNA as their genetic material. The manner in which the information in these genes are encoded or expressed is known as the GENETIC CODE. Genetic code comprises of all the codons that specifies amino acids in all living organisms. Only 20 amino acids in different sequential pattern makes up all proteins.
Nearly all living organisms use the same genetic code, as a codon does not specify a different amino acid in another organism. It is universal in all organisms that AUG codon specifies Methionine. Only slight differences to this pattern of genetic expression has been discovered, hence, the genetic code is said to be NEARLY UNIVERSAL.
The idea of a nearly universal genetic code refers to the common genetic 'language' shared by nearly all organisms. This means that, across an extraordinarily diverse array of species, the same sequences of DNA and RNA (the genetic code) translate to the same amino acids, which, in turn, build the same proteins. The universality of this code strongly suggests that all life shares a common origin.
The nearly universal genetic code refers to the fact that virtually all living organisms use the same codons, or sequences of DNA and RNA, to code for specific amino acids, which are the building blocks of proteins. This conservation of codons is seen across a vast array of species, with minor exceptions. For instance, if the mRNA encoding the globin protein in horses is transferred to a tulip cell, the tulip would synthesize the same protein, suggesting a common origin of all life on Earth.
The 64 possible combinations of triplet codons coding for 20 amino acids and with the occurrence of only one genetic code demonstrates the idea of degeneracy in the genetic code. This means that more than one codon can specify the same amino acid. For instance, unusual amino acids such as selenocysteine and pyrrolysine have been found in archaea and bacteria, which use unique codons.
Ultimately, the universality and degeneracy of the genetic code highlight the homologous characteristic shared by all species suggesting they share a common ancestor. This is powerful evidence for the shared biochemistry in all forms of life.

Answer:
So that they can be absorbed by the body.
Explanation:
Carbohydrates are complex and sugars are simple form of carbohydrates. Since carbohydrates is complex and not easily absorbed it is converted to sugars which the body can absorbed easily during digestion and it is converted to energy to drive the cells. Examples of sugars are sucrose,glucose.
Converting carbohydrates into sugars is essential as it provides energy to the body. During this conversion, glucose is produced, which is the body's main fuel. This process makes carbohydrates easier to digest and allows the sugars to be absorbed by the body.
Carbohydrates are essential macromolecules that originated from photosynthesizing organisms such as plants. These organisms use sunlight to convert carbon dioxide (CO₂) into sugar molecules like glucose (C6H12O6). This process of creating a larger, energy-storing molecule requires energy investment, as represented in the equation 6CO2 + 6H₂O + energy -> C6H12O6 + 6O2.
After consumption, the carbohydrates in our food are broken down into simple sugars via a process known as digestion. The digestion of carbohydrates begins in the mouth with the action of salivary amylase on starches and ends with monosaccharides being absorbed across the epithelium of the small intestine. The monosaccharides are then transported to the tissues, initiating the process of cellular respiration.
During cellular respiration, glucose is oxidized, releasing the energy stored in its bonds to produce ATP (Adenosine Triphosphate), which is the body's main fuel. This is why it's essential to convert carbohydrates into sugars. When consumed, carbohydrates provide much needed energy to the body, predominantly through glucose, a simple sugar. Converting complex carbohydrates into simple sugars allows for easier digestion and absorption by the body.

Answer:
c. limiting factor.
Explanation:
The limiting factors are environmental or ecological factors that act directly on the living beings of a population, limiting their size, since these factors determine their birth, mortality, migrations, etc. They are the ones that regulate the growth and expansion of a species.
If environmental factors are optimal for the development of a living being, they favor the growth of that organism in that biotope. But if any of these factors prevents the growth of a species, there is talk of a limiting factor.
Among these physical and chemical factors that determine the biotope include:
- Abiotic factors (do not depend on population density):
Climate:
Light. Only the most superficial organisms access it in water. On land, there is also competition in leafy areas to access it.
Temperature. Some living beings cannot live at the temperature that others live.
Water: It is necessary that it rains or that living beings can access water in order to live. If there is no water, they die.
Atmospheric pressure.
Non-climatic:
Soil factors: The chemical composition of the soil, its pH, salinity, etc. It makes some plant species may or may not survive in it.
Factors of the aquatic environment: The concentration of O2, dissolved CO2, the degree of salinity, the existence of currents, etc., limits the development of some organisms.
- Biotic factors (depend on population density):
Food. If they do not have enough food, the population will have to be smaller.
Interspecific relationships. The number of predators limits the number of prey, and vice versa.
Intraspecific relationships. The relationships established between individuals of the same species can also limit their existence.

Answer:
Acquired traits are due to changes in the life style, injury, loss of body parts, disuse of some body parts. These are the traits which occur in the somatic cells. Changes in the somatic cells are not passed on to the offspring belonging to next generation. Hence acquired traits cannot be passed on to next generation.
