In humans, brown eyes (B) are dominant over blue (b)*. A brown-eyed man marries a blue-eyed woman and they have three children,
two of whom are brown-eyed and one of whom is blue-eyed. Draw the Punnett square that illustrates this marriage. What is the man’s genotype? What are the genotypes of the children?
<span>The man is Bb, the two brown eyed children are Bb (B from dad and b from mom) the blue eyed child is bb. B (brown) is dominant where b (blue) is recessive. In order to be blue eyed you must have gained the recessive b from both parents as B will always dominate over b, so mom is bb. Because they also had a blue eyed child, it tells you that dad is B dominant because of his brown eyes and has a b recessive in order to pass the recessive b to his blue eyed child.</span>
Because these non native species can cause competition for the same food source as the native species thus making it harder for the native species to survive. Also the non native species could see the native species as food causing them to die out. As well as introducing new diseases that these native species don’t know how to defend themselves from
The answer is logistic growth.
It is modeled by an S-shaped curve. Carrying capacity (K) is the maximum individuals of a population that a habitat can sustain indefinitely
given the limited resources in the environment. Before this number
is achieved, the population grows exponentially and slows as it gets close. When
the K number is reached, the stationary phase enters.
The peripheral nervous system has - Somatic nervous system and Autonomic nervous system.
These systems control our body action by this controls all the types of muscles.
Explanation:
Somatic nervous system have - Cranial nerves and Spinal nerves
Autonomic nervous system have - Sympathetic and Parasympathetic system.
The somatic nervous system controls our voluntary and involuntary actions by cranial and spinal nerves and controls all three types of muscles such as cardiac, smooth and skeletal.
The autonomic nervous system controls the involuntary actions of our internal organs.
The sympathetic and parasympathetic system relates to all types of muscle.
The sympathetic and parasympathetic system accelerates and decelerates the heart beat respectively, by this controls the cardiac muscle.
The sympathetic and parasympathetic system stimulates and relaxes our internal organs respectively, by this controls the smooth muscles.
The sympathetic and parasympathetic system prepares our body as a whole for a action and also relaxes our whole body respectively, by this controls the skeletal muscles.
