Biogeographical studies use information for various fields, such as evolutionary biology, geography, geology, and climate science to determine how organisms evolved through time and how the moving of tectonic plates resulting in forming continents, mountain ranges and islands has affected their distribution.
Studies in this field explain how organisms that now live on different continents are very closely related and how the flora and fauna of islands are connected to one of the closest continents etc.
Advantages:
Enhance protein digestion. The addition of a protease to a feed can result in improved amino acid digestibility across various protein sources. Minimize the impact of anti-nutritional factors.
Disadvantages:
Enzymes can be denatured by even a small increase in temperature. They are also susceptible to poisons and changes in pH. This means the conditions they work in must be tightly controlled
Enzymes can be expensive to produce
Contamination of the enzyme with other substances can affect the reaction.
Hope it helps!
Answer:
It is expected to observe individuals exhibiting green, yellow, blue, and white colors in a phenotypic ratio of 9:3:3:1, respectively.
Explanation:
This example is a classic case of a dihybrid cross involving two unlinked genes that differ in the same observed trait. In this case, the genotype double homozygous recessive is white, while the presence of one dominant allele in one of these genes results in individuals with either blue or yellow color. Finally, the presence of two dominant alleles results in individuals with blue color.
Phenotypic and genotypic ratios:
gene 1 two alleles U u
gene 2 two alleles N n
Cross:
UuNn x UuNn
uunn: white color (1/16)
U_nn: yellow color (3/16)
uuN_: blue color (3/16)
U_N_: green color (9/16)

Characteristics of Endocytosis:
* use energy
* takes substances into a cell
* moves substances in vesicles
Characteristics of Exocytosis:
*use energy
*releases substances outside a cell
*moves substances in vesicles.
Both use energy and move substances in vesicles.
