The correct options are as follows:
1. USE, B.
Land use refers to the function of a particular land, that is, what the land is been used for. For instance land can be used for agriculture, construction of roads, residential apartments, hotels, zoos, etc. Land use differs in the urban and rural settings. In the rural settings, land is usually used for farming and forestry while in the urban setting, land is usually used for construction purposes.
2. LUC, OPTION B.
The modification of the earth's surface due to land use is called LAND USE CHANGE, LUC. A lot of changes occur when man use lands for different purposes. For instance, examples of land use change include: reduction in forest biomass, conversion of forest and grassland to pasture, etc,
Answer:a. Draw Punnett squares for each couple (you may need to do more than 1 square/ couple)
Baby 2 MUST belong to the Browns because Mr. Brown is the only parent with an A allele to
contribute… then the rest works out as follows:
b. To which parents does baby #1 belong? Why? Hint you may want to refer to your Punnett
squares.
Baby 1 must belong to the Smiths, because they are the only ones with the possibility of EACH
having a recessive allele to pass down to the baby, Mr. Brown has type AB blood and therefore
only has the dominant A and dominant B alleles – no recessive allele possible.
Explanation:
Solution:
People that born with hemophilia lack or have a low amount of a clotting factor.
Coagulation factors are proteins necessary for normal blood clotting.
Coagulation factors are found in blood plasma. These factors act with Thrombocytes to clot blood.
However, hemophilia is not a decrease in Thrombocytes but a decrease in coagulation factors due to genetic causes.
Diagnosis includes screening tests and clotting factor analysis. Screening tests are blood tests that show whether the blood is clotting properly. Clotting factor tests can reveal a deficiency of clotting factors in the blood plasma and determine the level of severity of hemophilia.
As the coagulation factors are in Blood plasma, we can conclude that the correct answer is:
BLOOD PLASMA
I believe it is behavioural isolation. When there are changes within a certain species, e.g. new birdcalls are formed in certain individuals in a species, "traditional" birds may not like such mating calls and only choose to mate with the more common birdcalls from majority of the birds. There are also some birds that may like the new birdcalls, and choose to mate with birds with those birdcalls. They become genetically isolated as they continue such behavior. Eventually, through genetic drift and other mutations, different species form from a single specie.
Hope this helps! :)
