If we label the yellow parrot alleles with YY (a homozygote) and green parrot gg (also a homozygote) we can cross these two individuals and determine their future offspring.
YY x gg
Yg Yg Yg Yg
All of the offspring would receive one dominant Y allele from the yellow parent and one recessive allele from the green parent and their genotypes would all be Yg (heterozygotes). Since Y allele is dominant, all of the offspring would have yellow feathers.
Answer:
The following can be deduced from the life history of bark beetles;
* All bark beetles life stages are spent in the phloem, internal bark, and bark, aside from when grown-ups leave the tree they created in to travel to new host trees. Bark beetles feed on the phloem of their host trees during grown-up and larval stages.
* Many bark beetles travel toward debilitated host trees, be that as it may, during environmental conditions ideal for population improvement, populaces may develop quickly and effectively assault healthy trees.
Explanation:
Bark beetles determine their name since they live and create in the bark and wood of trees and bushes. Grown-ups unearth egg displays in living bark (phloem).
Bark beetles are the most dangerous creepy insects in western coniferous woodlands. It has been assessed that 90% of insects caused tree mortality and over 60% of the complete insect caused loss of wood development in the US is because of bark beetles.
Answer:
2.Bees and the butterflies take nutrients away from the flowering plants.
4.Bees and butterflies pollinate the flowers by flying from one to another without any harm to themselves.
Explanation:
Answer:
A microaerophilic organism grows only in the middle depth area of a Fluid Thioglycollate Medium tube because the mid area of the tube has moderate levels of oxygen and significantly higher amounts of carbon dioxide.
Explanation:
A microaerophile organism is one that cannot survive or thrive in a region with normal levels of atmospheric oxygen. It prefers environments with a lower concentration of oxygen and higher amounts of carbon dioxide.
Fluid Thioglycollate Medium tube is used during experiments to determine which organisms are aerobes (that is can thrive well in and require oxygen to survive), from those which are anaerobes (cannot tolerate oxygen and may die in its presence) and microaerophilic organisms.
At the bottom of the Fluid Thioglycollate Medium tube, there is zero oxygen whilst at the top, there is lots of oxygen. Towards the midsection, there is less oxygen and more carbon dioxide. The Thioglycollate mixture contains the following:
- Sodium thioglycollate
- Thioglycolic acid
- L-cystine,
- Methylene blue, and
- 0.05% agar.

Answer:
the process whereby organisms better adapted to their environment tend to survive and produce more offspring. The theory of its action was first fully expounded by Charles Darwin, and it is now regarded as be the main process that brings about evolution.
