6. In making decisions about land use, what criteria might be used to determine the kinds of evidence that should be required? D
AysviL [449]

Location of land, resources available around and for the land, environment around the soil, texture of soil and water availability.

<h2>Criteria needed for land use</h2>

Resources available around and for the land, environment around the soil, texture of soil and water availability are the criteria which can be used to determine the kinds of evidence that should be required in making decisions about land use.

If the land has all resources needed for agriculture then the land must be use for agriculture purpose while on the other hand, if the land has limited resources such as water and poor soil texture then the land will be used for infrastructure so we can conclude that available resources to the land decides the usage of land.

What happens when the cycling of matter in ecosystems is disrupted
V125BC [204]

Answer:

When cycling of matter in the ecosystems is disrupted, the whole ecosystem will be adversely affected. Matter includes living organisms such as plants, animals and microorganisms while non living things such water, air and nutrients etc. If plants are removed from the ecosystem system, then the whole ecosystem is destroyed because plants are the producer which make food for herbivores. These herbivores are eaten by carnivores and so on.

1.) Explain how you identified the chromosomes in order to place them in the correct pairs.
aivan3 [116]

Answer:

A chromosome is a DNA (deoxyribonucleic acid) molecule with part or all of the genetic material (genome) of an organism. Most eukaryotic chromosomes include packaging proteins which, aided by chaperone proteins, bind to and condense the DNA molecule to prevent it from becoming an unmanageable tangle. This three-dimensional genome structure plays a significant role in transcriptional regulation.Chromosomes are normally visible under a light microscope only when the cell is undergoing the metaphase of cell division (where all chromosomes are aligned in the center of the cell in their condensed form). Before this happens, every chromosome is copied once (S phase), and the copy is joined to the original by a centromere, resulting either in an X-shaped structure (pictured here) if the centromere is located in the middle of the chromosome or a two-arm structure if the centromere is located near one of the ends. The original chromosome and the copy are now called sister chromatids. During metaphase the X-shape structure is called a metaphase chromosome. In this highly condensed form chromosomes are easiest to distinguish and study.In animal cells, chromosomes reach their highest compaction level in anaphase during chromosome segregation.

Chromosomal recombination during meiosis and subsequent sexual reproduction play a significant role in genetic diversity. If these structures are manipulated incorrectly, through processes known as chromosomal instability and translocation, the cell may undergo mitotic catastrophe. Usually, this will make the cell initiate apoptosis leading to its own death, but sometimes mutations in the cell hamper this process and thus cause progression of cancer
