The correct answer is:

Testing a hypothesis

Explanation:

Hypothesis testing is an action in statistics how an analyst tests a suspicion concerning a population parameter. Hypothesis testing is done to indicate the outcome of a hypothesis presented on individual data from a larger population. Hypothesis testing is an imperative idea in statistics. A hypothesis test estimates two together private statements about a population to settle which statement is best maintained by the sample data.

Describe the size, brightness, temperature of a Neutron star/ Protostar:
vodomira [7]
Neutron star: a newly formed neutron star can have a temperature of about 10^11 Kelvin to 10^12 Kelvin, but it can drop to 10^6 Kelvin. Its brightness is a million times fainter than the sun's brightness because of its size and distance from a point of view.

Dwarf star: Yellow dwarfs are small, main sequence star. <span>Red dwarfs are the most common type of star, </span>it's a small, cool, very faint, main sequence star whose surface temperature is under about 4,000 K.

Main sequence: has a temperature of about 10 million K. Its luminosity depends on the size and the mass of the star.

Red Giant: not normally as bright as the main sequence but it can create 1,000 to 10,000 times the luminosity that the sun gives off. The outer atmosphere is inflated, making the surface temperature to be as low as 5,000 K.
 
Supergiant: These stars have very "cool" surface temperatures that can range between 3500 and 4500 K (more or less). Depending on proximity, size, and mass, their luminosity can be either very high or very dim... though, they are normally very large stars.

Question 10
creativ13 [48]

Answer:

M₂  = 0.08 M

Explanation:

Given data:

Initial volume = 25.0 mL

Initial molarity = 0.500 M

Final volume = 150.0 mL

Final molarity = ?

Solution:

Formula:

M₁V₁          =     M₂V₂

0.500 M × 25.0 mL = M₂ ×  150.0 mL

M₂  = 0.500 M × 25.0 mL /   150.0 mL

M₂  = 12.5 M.mL /150.0 mL

M₂  = 0.08 M

In pea plants, yellow seeds are dominant to green seeds. A heterozygous yellow-
san4es73 [151]

Answer:

The phenotypic percentage of having yellow or green seeds is 50% for having either of the two colours

Explanation:

The crossing to determine the offsprings is shown in the image attached where we have two green (Yy) seeds and two yellow (yy) seeds as offsprings.

Thus, <u>the phenotypic percentage of having yellow or green seeds is 50% for having either of the two colours</u>.

Note, the dominant allele is "Y" while the recessive allele is "y". Thus, Yy would produce a yellow colour while yy would produce a green colour (as both mentioned in the question).

Also note that phenotype describes the outward properties/characteristics of an individual.
