Answer:
All of the systems on Earth are classified as open systems. However, the Earth system as a whole is considered a closed system because there is a limit to how much matter is exchanged. Our Earth system has four spheres: the atmosphere, the biosphere, the hydrosphere, and the geosphere.
Explanation: The term “Earth system" refers to Earth´s interacting physical, chemical, and biological processes. The system consists of the land, oceans, atmosphere and poles. It includes the planet's natural cycles — the carbon, water, nitrogen, phosphorus, sulphur and other cycles — and deep Earth processes.
A system is a group of independent parts that work together as a whole. The Earth has four major systems or spheres. These systems are the geosphere, the hydrosphere, the atmosphere, and the biosphere.
Biotic and abiotic factors both influence each other. The abiotic factors will determine what kinds of biotic factors will present

Explanation:
A nursery bed can be defined as a specially prepared temporary plot of land or garden which serves as a home for raising seedlings (young plants) prior to planting them in the main location (area). Thus, when older trees in the environment or surrounding dies or are cut-off, these younger plants (trees) propagated in the nursery bed are transferred to replace them.
<em>Some of the criteria or requirements for setting up a nursery bed are;</em>
1. Shed: this is one structure essential in propagating young trees.
2. Location/Site: a place near a source of water should be chosen because water is essential for plant growth and coolness from extreme heat caused by the sun.
3. Storage place for tools and equipment: it is important to have a complete set of tools or their substitute to be able to carry out all nursery activities properly.
4. Boxes, pots, and plots for germinating seeds: there are three places to germinate seeds, young plants, and young trees. Pots are used for germinating young trees while boxes and plots are used for raising seedlings.
5. Soil type: different plants need different types of soil. These includes clay, loamy and sandy soil.
Explanation:
both IA and IB are dominant- A and B groups show co-dominance
Inheritance describes the way in which certain traits are passed onto offspring of sexual reproduction. For co-dominance, both of a gene's alleles are present, and notable in the phenotype.
Blood glycoprotein alleles are crucial to blood type determination for the ABO system in humans- i does not lead to modifications, while IA leads to the modification of adding N-acetylgalactosamine to the H-antigen on red blood cells; and IB adds galactose
= blood type AB while = blood type A while = blood type B. Since are both dominant over ii, those with that allele have blood type O.
The nucleus is a large membrane-bound organelle that houses the genetic information, DNA, in the cell. Sequences of DNA make up genes which can have different forms called alleles and comprise the genotype. DNA is transcribed into mRNA and later translated into amino acids which are linked together by rRNA to form proteins. These proteins, when expressed, are referred to as an organism's phenotype.
