The thymus is a vital role in creating white blood cells.
Which mode of inheritance produces heterozygotes with phenotypes that differ from either homozygote but typically more closely resembles one homozygous phenotype than the other?"
A) complete dominance
B) incomplete dominance
C) codominance
D) epistasis
E) incomplete penetrance
Answer:
B) incomplete dominance
Explanation:
Incomplete dominance occurs when the dominant allele of a gene is not able to mask the expression of the recessive allele completely. This results in the expression of a phenotype in the heterozygous genotypes that differ from both homozygous genotypes. However, the phenotype of the heterozygote is closer to one of the homozygous genotypes.
For example, the petal color in four o'clock plant is controlled by a gene with two alleles R and r. Here, the "R" allele can not produce enough pigment in heterozygous conditions to completely mask the expression of the "r" allele and the phenotype of the "Rr" plant is "pink". On the other hand, the phenotype of "RR" plant is red while that of the "rr" plant is "white".
Answer:
False
Explanation:
The sugars on the basis of the number of glucose or sugar units can be categorized into two categories:
1. Simple sugars: The sugars which contain one or two sugar units called mono and disaccharides.
2. Complex sugars: The sugars which contain more than two sugar units are complex sugars.
The simple sugars like glucose, galactose are easily digested by the digestive system of the human body and easily absorbed by the cells.
Since the simple sugars or simple sugars are small in their structure compared to the complex carbohydrates therefore false is the correct answer.
Answer:
1.The eyes, a sensory organ, see the ball.
2.Sensory nerves transmit the information to the brain.
3.The brain processes the information.
4.The brain sends signals to the motor nerves.
5.Motor nerves carry the signal to the hand muscles.
Explanation:
When we receive a stimulus by any of our 5 senses (sight, touch, smell, hearing or taste) our body will react to this. Once that the stimulus is received ( in this case seeing the ball) a signal is send through the sensory nerves to the brain. In the brain the information will be processed and an answer will be given through the motor nerves in order to move the muscles and catch the ball. All this process is made in seconds.
The tolerable upper intake of zinc for an adult is 40 mg per day.
But the recommended daily intake of Zinc (RDA) is 15 mg per day for an adult. Nevertheless, this contribution must be adapted according to your age and your activity. Attention, in case of excessive excess, zinc can become toxic.
The tolerable dose (without side effects) can be up to 40 mg per day, it is prescribed in case of infection as during cooling. Attention in case of treatment with 40 mg of zinc per day, the maximum duration of treatment is 4 days.
