Answer:
In the canary bird, green feathers are the result of a dominant gene “G” and the cinnamon color is the result of the recessive gene. This is an example of sex linked inheritance.
Write the genotype for a homozygous green female
GG
Write the genotype for a cinnamon female.
gg
Write the genotype for a cinnamon male.
gg
Write the genotype for a green male.
GG
Write the genotype for a female carrier
Gg
Cross a pure dominant female with a cinnamon male.
GG x gg= Gg, Gg, Gg, and Gg 4:0 All green
How many of the offspring would be cinnamon male?
none as all the offspring is green feather
Explanation:
I think the answer is natural selection
Answer:
You, a human being and a pet share a mutualistic relationship. A mutualistic relationship is a relationship in which two different species of organisms benefit each other. You and your pet have a mutualistic relationship because a pet provides companionship, comfort, in some cases protection (depending on the pet), and protecting your home from rodents (also depending on the pet). While animals provide these services for humans, in return we provide food, water, shelter, and love/comfort for the animal. Both organisms (you and your pet) benefit from your relationship therefore it is mutualistic.
Answer:
Please find the detailed explanation/description on how to use the light microscope to view a wet mount of a protist. The 9 structures mentioned in the question are in CAPS.
Explanation:
- Firstly, the slide containing the wet mount of the protist is prepared and placed at the centre of a lowered STAGE. The STAGE CLIPS over the sides of the slide are used to hold it in place.
- The revolving turret or nosepiece is turned so that the LOWEST POWER OBJECTIVE LENS is in position i.e. directly above the sample/slide. The SCANNING OBJECTIVE LENS, the lowest objective lens with power of 4x is used initially.
- The slide is viewed through the EYEPIECE, and the image is brought into focus using the STAGE KNOBS.
- The COARSE FOCUS KNOB is turned until the protist on the slide is brought into broad focus. The FINE FOCUS KNOB is then used to bring the image on the slide into sharp focus.
N.B: The OBJECTIVE LENS should not touch the cover slip on the slide during this process.
- When the protist on the slide is clear using lowest power objective lens, the revolver turret can be rotated to allow HIGHER POWER OBJECTIVE LENS.
- Due to higher magnification of the HIGH POWER OBJECTIVE LENS, the protist might need to be refocused using the FOCUS KNOBS.
