Answer:
Sickle Cell Anemia:
What is the difference between sickle cell trait and sickle cell disease?
Huntington’s disease:
How does the mutant protein huntingtin cause Huntington’s disease?
Explanation:
Answer:
If both parents do not have sickle-cell anemia, than the possibility is low.
Explanation:
If both parents have the sickle-cell trait, their offspring has a 25 percent chance of getting sickle cell anemia and a 50 percent risk of them having sickle cell trait. Meanwhile, there is also a 25 percent chance of the child not getting it at all.
If one parent has sickle cell anemia and the other has sickle cell trait, then their offspring with have a 50 percent chance of getting sickle cell anemia and a 50 percent chance of getting a sickle cell trait.
When both parents have sickle cell anemia, their child will definitely have it.
The answer for the above question is the Avascular Necrosis. It occurs as an interruption in the blood flow within the bone resulting in the death of the hematopoietic cells, osteocytes, and marrow fat cells making up the bony structure. It is also called osteonecrosis or ischemic bone necrosis, which occurs when there is loss of blood to the bone, since the bone is a living tissue that needs blood, this interruption of blood supply will result to the death of the bone.
The adaptive advantage of a fungus producing and secreting a bacterial inhibitor would be that it protects against microbial competitors: is an extensive surface area well suited for invasive growth and absorptive nutrition.
Fungus
A fungus is any eukaryotic organism that includes microbes like yeasts and moulds, as well as the more recognisable mushrooms. These organisms are classed as a kingdom distinct from the other eukaryotic kingdoms, which include Plantae, Animalia, Protozoa, and Chromista in one traditional taxonomy.
The presence of chitin in fungi's cell walls distinguishes them from plants, bacteria, and some protists. Fungi, like animals, are heterotrophs; they obtain nourishment by absorbing dissolved molecules, usually by secreting digestive enzymes into their surroundings.
Fungi, like plants, use chemical defence, which involves the creation of poisons that affect the growth, development, or viability of the antagonists.

Habitats of the plants:
X : winter or cold mountainous habitat
Y : desert habitat
Z: Aquatic habitat
Explanation:
The X plant leave morphology suggests that thick wax coating of leaf helps it to retain water in it. Such plants are called conifers. They are not shed every year so suitable for sunlight to be captured for photosynthesis. In cold regions heavy wind happens cone like leaf is able to resist the winds and prevent it from falling. The cone like structure of leaves help them let the snowfall.
The plant Y leaves and root morphology suggests that it is well suited for dry lands or desert as where less water is there. They store water for longer time when it rains because of the extensive root system. The spine leaves help in reduced transpiration as water scarcity is there.
The plant Z leaves morphology suggests that thin and ribbon structure leaves can help them resist the pressures of flowing water as there are air space in the leaves which provide buoyancy to the leaves.
