Answer:
Photosynthesis occurs in eukaryotic cell structures called chloroplasts. A chloroplast is a type of plant cell organelle known as a plastid. Plastids assist in storing and harvesting needed substances for energy production.
Explanation:
Answer:
Chi square value = 0.3
In order to find the expected value, an assumption of purple flower colour dominance over white flower colour has to be made.
Explanation:
<em>First, we will assume that the purple flower trait is dominant over white flower trait, and that the alleles segregate according to Mendelian standard. Hence, the expected F2 phenotypic ratio will be 3:1.</em>
In order to get the Chi square, the expected phenotype frequency will be calculated thus;
Expected frequency (E) for purple flowered plants = 3/4 x 160 = 120
Expected frequency (E) for white flowered plants = 1/4 x 160 = 40
Observed frequency (O) for purple flowered plants = 123
Observed frequency (O) for white flowered plants = 37
<em>Chi square 
= 
</em>
For the purple colour flower
, which gives 0.075
For the white colour flower
, which gives 0.225
<em>Total = 0.075 + 0.225, which gives 0.3</em>
The tadpole contains gills but doesn't have legs nor lungs.
however the adult frog contains the opposite. It has both lungs and legs but doesn't have gills. This is due to tadpole leaves in the water and the frog leaves on both land and sometimes in the water.
there's a mistake in the question, weight isn't measured in pounds its measured in newtons, mass is measured in pounds
im going to assume ur asking why our weight is different on the moon and earth, and why the mass remains the same
weight is how many newtons of gravity is acting on you. the gravitational field strength on earth and moon are very different. on earth its 9.8N and on the moon its 1.6N. Because the force of gravity is weaker on the moon, you weigh less.
Functionalism. It is according to the concept 'survival of the fittest'
