Answer:
a) p=0.665
b) q=0.335
c) 2pq=0.445
d) (0.665^2)+(0.335^2)+(2*0.665*0.335)=1
Explanation:
For solve this exercise I will use the Hardy-Weinberg principle. We have the following:
a) and b)
number of purple flowers=142
number of white flowers=18
total number of flowers=160
frequency of white flowers=q^2=18/160=0.112
q=0.335
if
p+q=1
Clearing p:
p=1-0.335=0.665
c) the heterozygous is 2pq:
frequency of heterozygous allele: 2pq=2*0.665*0.335=0.445
d) p^2+2pq+q^2=1
(0.665^2)+(0.335^2)+(2*0.665*0.335)=1
Answer:
Plants. Some Bacteria. Algae. These 3 are the photosynthetic autotrophs..
Why the others don't fit:
Athropods are hetertrophs. Not all bacteria are autotrophs. Only some protists are autotrophs.
<h3>Phototropism</h3>
Yes, the given activity is a correct example which describes phototropism
Phototropism is an adaptation or a survival mechanism undertaken by some plants to receive maximum sunlight in order to prepare more food and energy through photosynthesis.
Explanation:
Phototropism takes place through receptor proteins called phototropins which act as blue light photoreceptors.
Phototropic activity:
Phototropism can best be observed by planting few plants including phototropic plants in pots and keeping them near the window to receive sunlight.
The natural bending of phototropic plants towards the window denotes their inclination towards sunlight.
The growth of sunflower plants facing towards the sun and blooming of lotus flower under sunlight are all examples of phototropism.
Other plants which are phototropic are Phalaenopsis, azuki beans, fungus of Phycomyces species, etc.
Answer:
The TATA box is an alternating sequence of Adenine and Guanine nucleotides that transcription factors bind to. The TATA box is found just before a gene. The transcription factors tell the RNA polymerase where to bind to begin transcription. This ensures the RNA polymerase will know where to start and which gene to transcribe.
Explanation:
Answer:
ATP.
Explanation:
Glycolysis may be defined as the process by which breakdown of glucose molecule occurs into the form of ATP. Glycolysis can occur in the presence as well as in the absence of oxygen.
The initial step of the glycolysis is the formation of glucose-6-phosphate from the glucose molecule. The ATP starts this process of the glucose oxidation with the help of the enzyme hexokinase. The first step of the glucose oxidation is the energy driven process that requires the ATP molecule.
Thus, the correct answer is option (4).
