The answer is b. a polygenic trait that is influenced by the number of alleles present.
There are three genes linked to a common form of glaucoma, so it must be the polygenic (meaning more than one gene included) trait. The polygenic traits are influenced by the number of alleles. In this case, there are more than 20 genetic loci which means there must be a great number of alleles for all loci.
are primarily sugars and starches
are the most readily available source of energy for organisms
are the largest of the four main biological macromolecules
Answer:
are the most readily available source of energy for organisms is the correct answer.
Explanation:
Behavioural genetics is the study of the effects of genes as well as well the environment on the behaviour of the individuals. The scientists who study the Behavioural genetics are known as behavioural geneticists.
In this case Dr. Hakim is studying the influence of genes and the environment on the aggression, which is a kind of behaviour. Hence, Dr. Hakim is a behavioural geneticists, and he works in in the field of behavioural genetics.
Gas
Liquid
Plasma
Correct answer: Gas
b. are typified by tweezers or forceps
c. have load at one end of the lever, fulcrum at the other, and effort applied somewhere in the middle
d. in the body can operate at a mechanical advantage or mechanical disadvantage, depending on specific location
Answer: d. in the body can operate at a mechanical advantage or mechanical disadvantage, depending on specific location.
Explanation:
A first-class lever is defined as the force in which fulcrum is present in the center and the load and effort on each side of the fulcrum. First class lever moves over a large distance to move the load to a smaller distance.
First-class lever can be operated at mechanical advantage or disadvantage that it can aid in work by changing the direction of the force and by increasing the efficiency. As the the fulcrum is between the load and the effort so the length of the effort arm divided by the length of the effort arm.
If the fulcrum is closer to the effort, it will operated at mechanical disadvantage and vice versa.
Example of first class levers includes scissors, a claw hammer, a see-saw and a weighing balance.
Hence, the correct option is D.
B. freeze
C. rinse
D. soak
Answer: D. soak
A dye is a colored substance that has the affinity for the substrate on which it is applied. A dye is typically an organic compound, which is mixed with a suitable binder, to keep it in a liquid state. It is used to provide color to the cloths.
When the dye has been applied to the shirt, all that remained was to soak it because, the binder or solvent will be absorbed by the shirt by capillary action, and the dye will impart it's color.
