Temperature, viscosity, and amount of dissolved gases
Answer:
Disruption such as deforestation or mining can destroy the habitat, leading to water pollution, mud slides, and loss of soil. With the habitat affected, the animals the grey fox feeds on, such as rabbits or mice, will be affected as well, leading to the grey fox losing a source of food. By limiting the diet of the grey fox, other predators will be more likely to compete with the grey fox, disrupting its niche.
Answer:
Intrusive rocks are coarse-grained in texture and crystallise slowly from magma deep in the earth's crust. Extrusive rocks are fine-grained in texture and crystallise quickly from lava on or near the earth's surface. The mineralogy determines the type of rock.
Answer:
The possible arrangements of alleles on the F1 progeny's chromosomes will be AZ/Az or aZ/az
Explanation:
The genotype of F1 progeny is AaZz
The allele pair of gametes would contain one allele for characteristic represented by "A or a" and other allele for characteristic represented by Z or z"
Thus, total four allele pairs will be formed.
First allele pair would be - AZ
Second allele pair would be - Az
Third allele pair would be - aZ
Fourth allele pair would be - az
Hence, the possible arrangements of alleles on the F1 progeny's chromosomes will be AZ/Az or aZ/az
Answer: DNA polymerase I is able to proofread; DNA polymerase III is not.
Explanation:
Escherichia coli is a gram negative anaerobic bacteria that is found in the gastrointestinal tract of and humans and animals. Escherichia coli has 5 types of DNA polymerase.
a. Polymerase I is used to repair any damaged DNA and proof reading
b. Polymerase II is used in proof reading, DNA Replication and repairs.
c. Polymerase III is primarily responsible for DNA replication. It also has the ability to proof read.
d. Polymerase IV is used to change genetic information of Escherichia coli.
e. Polymerase V is used in DNA repair in Escherchia coli.
