12. Given the human pedigree to the right, is the trait indicated by
Scorpion4ik [409]

Answer:

Darkened shapes are recessive

Explanation:

In the pedigree shown, we can see that 2 parents that are unshaded shapes have 2 children that are shaded shapes. This would be impossible if shaded shapes were dominant and unshaded shapes were recessive. This is because parents that have a recessive trait have 2 of the same alleles. So if 2 parents that both have a recessive trait have a child, the child will definitely have that trait. But we can see that this is not the case, the parents have 2 offspring that have different phenotype from the parents. This must mean the parents are heterozygous, meaning that they both have 2 alleles that are different. The dominant allele masks the recessive allele, so the dominant allele is expressed. In this case, the children inherited 2 recessive alleles, 1 from each parent, making them have a different phenotype from the parents.

<h2>Proportion of mottled fish </h2>

Explanation:

  • A predator can be defined as an organism that makes the other organisms die to obtain them as food. Prey is the living being which is typically inferior and killed by the predator. Adaptation is a change in the physiology, morphology and genetic makeup of the organism which makes it suitable for survival in an unfavorable environment. Natural selection is the differential survival and reproduction of the organisms which exhibit better traits over the others
  • The population of the mottled fish is likely to increase due to natural selection. As the mottled fish color pattern match with that of the mottled background of the bottom of the lake. This will help the mottled fishes to camouflage the predator wading birds. These mottled fishes will remain undetected from the predator wading birds. The trait of the mottled pattern will be adapted by the light sandy brown fishes and the trait will be passed on the next generation as well. Hence, the proposition of the mottled fish will increase
  • Hence, the right answer is "the proportion of mottled fish will increase over time"

Describe the change in energy according to the Law of Conservation of Energy.
MAXImum [283]

Answer:

Law of conservation  of energy is one of the basic laws of the Physics.

Explanation:

According to the Law of conservation of energy, the total energy of an isolated system doesn't change, Energy may be transformed from one to another but the total energy of an isolated system remains constant.    There have different forms of energy like- kinetic energy, potential energy, chemical energy, thermal energy , electrical energy. the potential energy is converting into kinetic energy in the water falls. When kicking a football, energy is transferred from the body of the kicker to the ball.

Mandarinka [93]
The 2 types of bone markings being identified would be the opening on the occipitomastoid suture in which the internal jugular veins would travel to carry the blood from one's brain to the heart and the Mandibular condyle of the mandible that would then form the temporomandibular joint.
