Desertification is the process where fertile land becomes a desert.
Well one way desertification could impact an environment could be by a problem called OVERGRAZING.
Overgrazing happens when goats and cattle are kept in the same area for too long which results in then eating all the vegetation. If all vegetation is eaten, it is unlikely for it to grown back. Changes in political boundaries and companies buying land means that farmers rely on the water and land around them. This means farmers don't regularly move to new fertile areas.
Answer:
To study ancient climates using ice, scientists use data from polar mountain glaciers.
Explanation:
From the analysis and interpretation of natural traces, scientists describe the climate for hundreds to millions of years. Data derived from tree rings, ice cores, corals and ocean sediments, caves, among others, are observed. It is possible to gather these data with geophysical or biological measurements and some reconstructed climatic variables, such as temperature and rain level.
Polar mountain glacier data can be analyzed in laboratories to measure the amount of oxygen and methane, in addition to other parameters that help to indicate climatic variations. NASA researchers started Paleoclimatology in the 19th century, studying precisely the expansion of ice caps.
In miosis homologus chromosones seperate leading to duagyher cells that are not genetically identical . In mitosis the daughter cells are identical to the parents as well as to each other
DD is homozygous dominant, the dominant allele will shown so they will have dimples.
<h3>Homozygous dominant:</h3>
- When an organism is homozygous, it contains two copies of the same allele for a gene.
- When two copies of the same dominant allele or two copies of the same recessive allele are present in an organism, it is said to be homozygous dominant or homozygous recessive.
- Homozygosity is the presence of two dominant alleles (AA) or two recessive alleles (aa).
- The recessive allele is suppressed by the dominant one.
Heterozygous dominant:
- The two distinct alleles in a heterozygous genotype interact with one another. This controls how their characteristics are shown.
- This encounter frequently centers on dominance.
- The stronger allele is referred to as "dominant," whilst the weaker allele is referred to as "recessive." The dominant allele covers up this recessive one.
