In what studies do scientists not interfere with what is going on?
In observational studies, scientists do not interfere with the natural order of events and simply observe and analyze what is happening. This allows researchers to study phenomena in their natural state without influencing outcomes.
How do you calculate 100CC advertisement size?
In press publications, ad sizes are calculated by column centimeter (cc). Majority of the newspaper have fixed column size. i.e 1 CC = 3.8 - 4 cms. An average width of newspaper is around 8cc which is around 32 cms.
Hence, the ad sizes are mentioned as 20cc, 40cc, 60cc, 100cc etc.
An 100 cc ad is 16w x 25h (cms), where 16 cms is 4cc (16/4) so 4 x 25 = 100
Now majority of newspaper have started using sqcm as ad sizes, which is simply calculating width x height. For exp - 16w x 25h = 400 sqcm.
Average ad sizes
1 column classified ads - 4w x 10 = 10 cc = 40 sqcm
2 column ads - 8w x 15h = 45cc = 120 sqcm
*Quarter page - 12w x 20h = 60cc = 240sqcm
*Half Page - 32w x 25h = 200cc = 800 sqcm
*Full Page - 32w x 52h = 416 cc = 1664 sqcm
* Usually these are called by their names in stead of cc's and sqcm's.
The factors that affect the species diversity?
-Invasive species- When a new species that is not native moves into an area, it often won't have natural predators and can thus survive better than natives. They take over, and lower diversity levels by killing off other species
-Keystone species- a keystone species is a species which many others in the food chain rely on, if the keystone species has a problem or decrease in population the diverersity of the population will also decrease.
- Availability of resources- For instance food, shelter, nutrients, notice that rain forests which are abundant in rain forests show much diversity, while a tundra shows very little diversity.
- Stability of the community- for instane, tempreture shifts will cause a decrease in diversity because certain species have a small range of tempreture that they can live in. This is why coral reefs are decreasing in diveristy, they are very limited in teh tempreture they can live in.
I wouldn't agree that natural selection affects diversity levels as it is present at all times, in every ecosystem and does not fluctuate.
What level consumer gets food directly from a producer?
A level 1 consumer gets food directly from a producer. Level 1 consumers are herbivores or primary consumers that eat plants or algae.
Diversity of light refers to the range of frequencies, wavelengths, and intensities of light that are present in a given environment. It is important for supporting various ecosystems and ensuring the well-being of different organisms that rely on specific types of light for growth and survival. Increasing diversity of light can lead to a richer and more resilient ecosystem.
Give three types of biodiversity essential in preserving ecological systems and functions?
Three types of biodiversity that are essential in preserving ecological systems and functions are genetic diversity, species diversity, and ecological diversity. Genetic diversity is a measure of the variety of versions of the same genes within individual species. Species diversity describes the number of different kinds of organisms within a community or ecosystem. Ecological diversity means the richness of complexity of a biological community.
Why Submerged fermentation methods use in enzyem?
Submerged culture fermentation has been widely used for production of enzyme because in submerged fermentation unwanted metabolites are not produced and purification of enzymes takes place in easy way
In what ways are food materials mixed and propelled?
Food materials can be mixed through stirring, whisking, blending, or folding. They can be propelled by mechanical means such as blenders, mixers, or food processors, or by natural means such as gravity, steam, or air pressure. Mixing and propelling food ingredients help to ensure even distribution of flavors and ingredients in the final dish.
What is the difference between homozygosity and heterozygosity?
Homozygosity refers to having two identical alleles for a particular gene (e.g., both alleles are dominant or both are recessive), while heterozygosity refers to having two different alleles for the same gene (one dominant and one recessive allele). In homozygosity, an individual's genotype is either homozygous dominant or homozygous recessive, whereas in heterozygosity, the genotype is a combination of both dominant and recessive alleles.
What is the advantages of development needs exploitation of biodiversity?
Exploiting biodiversity for development needs can lead to the discovery of new resources for medicine, food, and materials. It can also promote sustainable economic growth and provide livelihood opportunities for local communities. Additionally, it can enhance ecosystem services such as pollination, water purification, and climate regulation.
India -a mega diversity country?
India has many religious and ethnic minority groups. Although 80% of Indians are Hindu, there are also Muslims, Jains, Buddhists, Christians, Atheists, Jews and others. In addition to diversity in religion, there are many different nationalities and tribal groups living in India. Add to this the variety of languages; Indo-Iranian, Dravidian and Austro-Asiatic being the main groups, and you can see the great diversity of India.
What will happen if biodiversity lost?
If biodiversity is lost no just animals will be affected but even us. This is lost is like setting a wave of imbalance through our ecosystem. There fore increase or decrease the population of other animals or plants
How can a gift of nature become a resource?
Something like a tree is a perfect example of this. Many organizations will allow you to plant a tree, for a donation. This is considered a gift of nature, and is also a natural resource.
Describe post-fertilization changes leading to formation of seeds?
After fertilization in a plant occurs, other changes may occur. An embryo - which is the future plant - is formed, endosperm cells become the embryo's source of nutrition, the ovule of the plant is now the seed, the ovary becomes the fruit of the plant, and the petals and sepals will fall off of the plant.
What do you call when both the parasite and the host benefit from each other?
The you're looking for could be mutualism. Double-click mutualism to check.
If you date yourself are you gay?
Dating yourself or loving yourself does not determine your sexual orientation. Being gay means being attracted to the same gender, not how you treat or love yourself. So, dating yourself does not make you gay.
Why is biodiversity important to Aboriginal people?
Biodiversity is important to Aboriginal people because it provides resources for their cultural practices, food sources, medicines, and traditional livelihoods. It is integral to their connection to the land, as well as their spiritual and cultural practices. Preserving biodiversity ensures the continuation of traditional knowledge and practices for future generations.

List the cells of the digestive systems?
The cells that are present in the human digestive system are
Mucosa - the layer that absorbs and secretes is made up of simple epithilium cells and connective tissue. There are specialized goblet cells that secrete mucus throughout the gastro intestinal tract located within the mucosa. On the mucoas there are the villi and microvilli.
Submucosa that is thick and vascular. It also has glands and nerve plexuses.
Mucscularis has inner circular layer and outer longitudinal layer of smooth muscle cells.
Serosa is a protective layer composed of avascular connective tissue and squamous epithelium cells.
