They would be a community.
Answer: Photoelectron spectroscopy is the energy measurements of photoelectrons emitted from solids, gases, or liquids by the photoelectric effect. Depending on the source of ionization energy, it can be divided accordingly into Ultraviolet Photoelectron Spectroscopy and X-ray Photoelectron Spectroscopy.
Explanation:
The right answer is Calcium
99% of the calcium is located in the bone, ensuring the skeletal strength and the hardness of the teeth.
In children and adolescents, it promotes bone growth; in young adults, it participates in the maintenance of bone capital; in the elderly, it contributes to the prevention of osteoporosis.
Beside the bone, calcium has other functions like blood coagulation, muscle contraction, nerve conduction, activation of certain enzymes.
Adequate calcium intake - consistent with the recommended dietary intakes - would have a preventive effect against high blood pressure.
Answer:
A food chain shows how energy is transferred from one living organism to another via food. It is important for us to understand how the food chain works so that we know what are the important living organisms that make up the food chain and how the ecology is balanced.
In the Linnean taxonomical system There are more organisms at the species level than at the genus level.
The correct option is D.
Explanation:
Carl Linnaeus is the father of taxonomy. His idea of classification is widely accepted and called as modern classification.
He categorized 7 levels based on the hierarchy as Kingdom, phylum , class, order, family, genus, species.
The Kingdom Animalia is the highest level of classification and species comes last.
The binomial nomenclature by him has made it very popular where distinguished species are categorized and is universal. In binomial nomenclature genus comes first (starts with capital letter) and species comes later (starts with small letter).
One genus will have many species. for example:
African lion Panthera leo (genus species)
Asian lion Panthera leo leo
So one genus will have many species in it.
