A pea plant with genotype PP (purple flowers) mates with a plant with the genotype pp (white flowers). The dominant allele P codes for purple flowers. The possibility that the offspring will have purple flowers is <u>100%</u>. If an offspring from this cross mates with a pp, the possibility of homozygous dominant genotype for the flowers will be <u>50%</u>.
<em>The dominant allele for the flower is P, and the recessive allele for the flower is p. </em>
<em>The possible genotypes of the purple flower is; PP or Pp.</em>
<em>The possible genotype of the white flower is; pp.</em>
The answer is b. hypothalamus.
Hypothalamus is a ventral part of diencephalon. It has many functions including control of hunger, thirst, body temperature, sleep, parenting behaviors, and circadian rhythms.
When an <span>animal </span>is not hungry, and it needs for food are satisfied, is called satiety. There is satiety center responsible for hunger. The center is located in hypothalamus.
Answer:
Explanation:
Phototropism is the growth of organism characterize by their response to light stimulus. It occurs mainly in plant and some Algae.
The response of plant to light enable them use energy from light needed for photosynthesis.
Plant Phototropism characterise some plant growth and development such as flowering,fruiting and seedling formation.
Inability of plant to respond to light reduces it ability to photosynthesize and make sugar needed for their activities ,flower and fruits. It reduces it growth and development.
We have positive and negative response. Positive response is the response of plant towards the direction of light while negative response is the response of plant away from light.
