Answer:

A solar eclipse can occur only when new moon occurs close to one of the points (known as nodes) where the Moon's orbit crosses the ecliptic. ... Therefore, the Moon's apparent size varies with its distance from the Earth, and it is this effect that leads to the difference between total and annular eclipses.

A population of wild-flowers was scored for flower color. There were 302 blue (BB) plants, 1857 violet (BR) plants and 811 red (

Paul [167]

Answer:

frequency of the blue (B) allele $= 0.4142$

frequency of the red (R) allele $= 0.5858$

The number of blue plants expected is $509.652$

The number of red plants expected is $1019.304$

The anticipated number of violet plants is $1441.341$

Calculated chi square value

$= 84.5320 + 42.5688 + 119.8692\\= 246.97$

Explanation:

Frequency of blue allele is

Frequency of blue allele is equal to sum of frequency of BB and half of frequency of BR

$\frac{302}{2970} + \frac{1}{2} \frac{1857}{2970} \\= 0.1016 + 0.3126\\= 0.4142$

Frequency of other allele

$1- 0.4142\\= 0.5858$

Amanda [17]

Answer;

-Pellicle

Explanation;

-Protist cells may contain a single nucleus or many nuclei; they range in size from microscopic to thousands of meters in area. Protists may have animal-like cell membranes, plant-like cell walls, or may be covered by a pellicle.

-On a paramecium's exterior is found the pellicle. The pellicle is stiff to maintain the paramecium's shape and provide stability but it is also flexible to allow movement. It also acts as an attachment site for external organelles such as cilia.
