Cell membrane is the answe
Answer:
The ratio of blue to white offspring in the progeny is 4 blue : 12 white.
Explanation:
<u>Available data:</u>
- The dominant allele K is necessary to synthesize blue flower pigment
- K is inhibited by the dominant allele D
- Plants with the genotype K- D- will not produce pigment (and their flowers will be white)
Cross: testcross for (Kk Dd) plants
Parental) KkDd x kkdd
Gametes) KD kD Kd kd
kd kd kd kd
Punnet square) KD Kd kD kd
kd KkDd Kkdd kkDd kkdd
kd KkDd Kkdd kkDd kkdd
kd KkDd Kkdd kkDd kkdd
kd KkDd Kkdd kkDd kkdd
- Whenever D is present, it inhibits the expression of the K gene, so every plant with the dominant D allele will be white. This plants´ genotype is kkD- or K-D-.
- Whenever D is absent and K is present, every plant with genotype K-dd will be blue.
- The recessive form for K and D genes will express white-flowered plants, with genotype ddkk
F1) Progeny genotype: 4/16 KkDd, white-flowered plants
4/16 Kkdd, blue-flowered plants
4/16 kkDd, white-flowered plants
4/16 kkdd, white-flowered plants
The ratio of blue to white offspring in the progeny is 4 blue : 12 white.
Blue-flowered plants: 4 Kkdd
White-flowered plants: 4 KkDd + 4 kkDd + 4 kkdd
Answer:
The ventral respiratory group (VRG) and the dorsal respiratory group (DRG) within the medullary rhythmicity area cooperate to establish the pattern for spontaneous ventilation and basal rate of ventilation which may be adjusted by impulses from related respiratory control centers in the pons; the ventral respiratory group (VRG) contains both inspiratory and expiratory neurons; the autorythmic inspiratory neurons stimulate the diaphragm and external intercostals for approximately 2 seconds to cause inspirations and then the antagonistic expiratory neurons fire for approximately 3 seconds to permit passive or stimulate active expirations; thereby inspiratory and expiratory neurons cooperate in a negative feedback control relationship, setting the basic rhythm of respiration (spontaneous ventilation, resting or tidal breathing (eupnea)); the dorsal respiratory group (DRG) neurons are involved in altering the pattern for ventilation in response to the physiological needs of the body for O2 and CO2 exchange and for blood acid-base balance; these neurons stimulate neurons in the ventral respiratory group (VRG) to achieve those effects; they are responsive to sensory information from chemoreceptors and mechanoreceptors.

here are some tips that have helped me! (I've been homeschooled for 5 years)
Explanation:
First, stay neet. Have clean notes, use different colors, assign a color to each subject.
Next, make commitments. Set timers for every 30 minutes and every 5 minutes (I.e. 1:30pm, 1:35pm, 2:00pm, 2:05pm) this was you can have scheduled breaks and keep yourself in check as well as giving you something to look forward to.
Personally, I need music/movies playing while studying so that I can enjoy studying so I recommend having a playlist/tv show that you wont have to constantly change if this is you as well.
I use noise cancelling headphone to watch/listen because I have a noisy family so I recommend telling them you're studying and that you can't hear them and then zone them out.
We've all heard of the chewing gum studying tip, but I recommend chocolate. It has ingredients that access your memorpheliac parts of the brain!
Finally, motivate yourself. Make it a priority and keep reminding youself how important it is to get this grade! keep reminding yourself of your gpa and your future. Also, it could help to get someone in your family to explain topics to you. sometimes as young people we understand better when things are explained to us/showed to us.
I hope this helps, its just what works for me.
