<span>Although a star might look brighter than the Sun, a comparison of its absolute<span> magnitude might help prove that they have the same real brightness.
Absolute magnitude is a concept that compares the absolute brightness of celestial objects. The absolute magnitude of an object is defined as the apparent magnitude it would have if it were viewed at a standard distance of 10 parsecs (32.6 light-years) with no dimming of its light. The more luminous an object, the smaller the numerical value of its absolute magnitude.</span></span>

Answer:

Although a star might look brighter than the Sun, a comparison of its <u>Absolute </u>magnitude might help prove that they have the same real brightness.  

Explanation:

Apparent magnitude measures the brightness of a celestial body from the Earth at its actual position.

Absolute magnitude is the apparent magnitude of the same body when it is at a distance of 10 parsecs.

A star might look brighter than the sun but actual comparison of the brightness can be done by comparing the absolute magnitudes of the two stars.

Chrysanthemums are short-day plants. select conditions in which you expect chrysanthemums to flower.
SpyIntel [72]

Due to the information that they are short-day plants, I would expect chrysanthemums to flower during the times of the year when <u>days are shorter and nights are longer. </u>

Plants require sunlight to grow and flower or produce fruit. While some plants require more light than others, almost all plants require some form of light to survive, much less flower. Pants are often classified according to the amount of light that they require, these classifications are:

  1. Day-neutral plants
  2. Long-day plants
  3. Short-day plants

Day-neutral plants are those that can flower regardless of the amount of light that they receive. These are very resistant species of plants that can thrive even through periods of prolonged darkness. Though they do well with even a small amount of light, they will still require it to survive. One example of this kind of plant is the <em>tomato</em>.

Long-day plants are, as the name may suggest, plants who thrive when the days are longer. These plants will not survive or bloom without many hours of sunlight every day. The <u>optimal conditions for this kind of plant are meet during the summer,</u> when the Earth is tilted towards the sun, causing longer days.

Finally, short-day plants are those who require little sunlight to flower. These are different from day-neutral plants in that during days with many hours of sunlight, they will not flower. These plants, such as the chrysanthemums, will only flower if daylight hours are low, meaning that <em>spring</em> and <em>fall</em> are <u>optimal conditions for these plants to prosper. </u>

Light in the understory is______, which promotes conversion of phytochrome to the _____form. Please choose the correct answer fr
Tju [1.3M]

The question does not have the option which are:

depleted in red light; inactive form

enriched in red light; active form

depleted in red light; active form

enriched in red light; inactive form

depleted in red light; inactive form

Answer:

depleted in red light; inactive form

Explanation:

The understory is the lower portion of the forest canopy which is characterised by the shade-tolerant species of the plants.

The light that reaches the lower portion or in the understory is depleted in the red light wavelength.

The phytochromes are the photoreceptor or blue-green pigment which response to the red and far-red wavelength. The low light converts the phytochrome to its inactive form Pr form which is reversible.

Thus, the selected option is correct.

Mom is A+. She has 2 children, one is O+ and the other is B-. (Note: Rh+ is RR or Rr, and Rh- is rr) What are the father’s possi
mezya [45]

Answer:

  • The blood group of the father must be B.
  • The genotype of blood group would be I^{B}i.
  • The Rh factor of the father can either be positive or negative.
  • Thus, the genotype of Rh factor of father would be either Rr or rr.

Rh factor:

The phenotype of the mother Rh factor is positive. Thus, she can have Rr or RR as her genotype as positive is a dominant trait.

If the genotype of the mother is RR then all the offspring would be positive for Rh factor. However, one of the offspring is Rh negative, that means the mother must be heterozygous that is, Rr.

The genotype of the father can either be Rr or rr in order to produce offspring with positive as well as negative Rh.

Blood group:

The blood group of the mother is A. Thus, the genotype can either be I^{A}I^{A} or I^{A}i.

However, the blood groups of the children are O+ and B+.

Thus, the genotype of the mother must be heterozygous that is I^{A}i.

The blood group of the father must be B with genotype I^{B}i in order to produce offspring with blood group O and B.
