what is sustainable development
Answer and Explanation
__________________________________________________________
According to UNESCO,
Sustainable development is the overarching paradigm of the United Nations. The concept of sustainable development was described by the 1987 Bruntland Commission Report as “development that meets the needs of the present without compromising the ability of future generations to meet their own needs.”
__________________________________________________________
There are four dimensions to sustainable development – society, environment, culture, and economy – which are intertwined, not separate. Sustainability is a paradigm for thinking about the future in which environmental, societal, and economic considerations are balanced in the pursuit of improved quality of life. For example, a prosperous society relies on a healthy environment to provide food and resources, safe drinking water, and clean air for its citizens.
__________________________________________________________
One might ask, what is the difference between sustainable development and sustainability? Sustainability is often thought of as a long-term goal (i.e. a more sustainable world), while sustainable development refers to the many processes and pathways to achieve it (e.g. sustainable agriculture and forestry, sustainable production and consumption, good government, research and technology transfer, education and training, etc.).

Which example shows the levels of organization in a multicellular organism from the smallest level to the largest?
O tissue, cell, organ, organ system, organism
Ocell, tissue, organ, organ system, organism
O cell, organ, organism, organ system, tissue,
oorganism, organ system, organ, tissue, cell
The best example that shows the levels of organization in a multicellular organism from the smallest level to the largest is cell, tissue, organ, organ system, organism. Thus, option B is correct.
What is cell theory?Cell theory is a scientific theory that's help to learn how living organisms are made up of cells, that's they are the basic structure unit of all organisms, and that all cells from pre-existing cells.
Prokaryotic cells are single-celled microorganisms known to be earliest on earth.Eukaroyotic cell have a nucleus enclosed within the nuclear membrane and form large and complex organism.
Difference between unicellular and multicellular.
The main difference between unicellular organisms and multicellular organisms is that unicellular organism is unspecialised it means all the body function depends upon only on the single cell and in multicellular organism there is specific cells for specific purposes.
Multicellular and unicellular organisms are perform almost all the life running activities and processes such as respiration, reproduction digestion, breathing, and metabolism.
In unicellular organism division of labour is at the organ level on the other hand in multicellular the division of labour at cellular, tissue, organs and organ system level. Unicellular organism has simple body organization and multicellular organism have complex body organism.
Therefore,the best example that shows the levels of organization in a multicellular organism from the smallest level to the largest is cell, tissue, organ, organ system, organism. Thus, option B is correct.

What
factors can be used to identify
prokaryotes?
Answer:
Prokaryotes are highly distinguished from Eukaryotes, mainly on the basis of their nucleus type. As the word itself suggest that Pro means Primitive and Karyon means Nucleus, while Eu means Specialized and Karyon means Nucleus. Hence, Eukaryotes are more equipped than Prokaryotes. Prokaryotes are mainly found between 1-10 µ and Eukaryotes between 5-100 µ. Prokaryotes mainly have a poorly defined nuclear region with only nucleic acids called a Nucleoid and lack a nuclear membrane too. On the contrary, Eukaryotes have a well defined nucleus with a clear nuclear membrane. Also, The being primitive, prokaryotes have one strand of chromosomes while Eukaryotes have many (46). Prokaryotes also lack a lot of cell organalls. The ribosomes in prokaryotes and eukaryotes are 70's and 80's respectively. Also, photosynthetic prokaryotes have membranous vesicles for synthesis food, unlike Eukaryotic Plants that perform it with Chlorophyll.

The sperm and the ovum are called haploid (as they have only 23 chromosomes) which is half the number of chromosomes seen in all the other human body cells. What is the significance behind the maintenance of this special chromosomal number in the male and female gametes?
Answer:
During the process of meiosis(The process of cell division through which the germ cells such as the reproductive cells are formed), the sex cells produced are haploids (have only 23 chromosomes). This is significant as during the process of fertilization, the nucleus of the sperm (containing 23 chromosomes) and the nucleus of an egg (containing 23 chromosomes too) fuse, hence, retaining the original number of chromosomes in the zygote formed. i.e 46 chromosomes.

The proper function of the stomates on the leaf (and therefore, the function of water and CO2 movement) is influenced most by which element
Answer:
Sunlight.
Explanation:
Sunlight is responsible for proper functioning of stomata present on the leaves because the stomata only opens when there is sunlight and when the stomata opens, carbondioxide gas is absorbed by the leaves from the air while the water is taken from the roots which combines together to form glucose and oxygen. Glucose is stored in different parts of the plant while some oxygen is used by the plants in the process of respiration while the remaining oxygen is released in the atmosphere through stomata.
