25% of the offspring (yellow) will have a XHXH genotype, they will be women expressing a healthy phenotype.
Other 25% of the offspring (green) will have a XHXh genotype, they are carriers of the hemophilian gene but express a healthy phenotype.
Other 25% of the offspring (orange) will be men with a XHY genotype, they won't be carriers so they will express a healthy phenotype.
The last 25% of the offspring (blue) will be men with a XhY genotype, they will express a phenotype of the hemophilia.
This means 25% of the of the offspring will be carriers and the 25% will be hemophiliacs.
They can produce an offspring with one another
DNA viruses utilize cellular enzymes for synthesis of their DNA genomes and mRNAs
Answer:
A) Rock climbing
Explanation:
The geosphere of the Earth includes all of its solid parts - the rocks, minerals, and landforms of its surface and interior. If we know this, we can conclude that the activity that involves interaction with the geosphere is rock climbing. Rocks are a part of the geosphere, and as we attempt to climb them, we are interacting with them.
Swimming and sailing are examples of interaction with the hydrosphere.
Riding in an airplane is an example of interaction with the atmosphere.
Answer:
Tetanospasmin toxin; Pulmonary embolism
Explanation:
Clostridium tetani produce a toxin called tetanospasmin. Tetanospasmin is the strong neurotoxin that blocks the motor neurons that control the muscles. Which results in stiffness of muscles.
Tetanus toxin ca cause blockage of lung artery (pulmonary embolism) and thus can cause death by:
- Stopping your breathing
- Pneumonia
- Cardiac arrest
