<h2>Resilience of bone</h2>
Explanation:
The resilience of bone comes from sacrificial bonds in or between collagen molecules
- Three major functions of bones includes
Providing structural support to the body
Providing protection to vital organs
Providing an environment for marrow (where blood cells are produced)
- There are two types of tissues which bones are composed of:
A hard outer layer called cortical bone which is strong, compact,dense and tough
A spongy inner layer called trabecular bone,this network of trabeculae is lighter and less dense than compact bone as a storage area for minerals (such as calcium)
- Bone is also consists of:
Bone forming cells (osteoblasts and osteocytes)
Bone resorbing cells (osteoclasts)
Non mineral matrix of collagen and noncollagenous proteins (osteoid)
Inorganic mineral salts deposited within the matrix
- Bone ends up being a good example of resilience because it is not static like it is perceived to be
An aphotic zone is a zone where light can be received from the sun (or other sources of light).
For example in the ocean, it will be the zone that begins a 200m deep and goes to the bottom of the sea.

Answer:
It is expected to obtain 576 individuals with normal wings and body with normal hair, 192 with normal wings and hairy body, 192 with vestigial wings and body with normal hair, and 64 with vestigial wings and hairy body.
Explanation:
Since only the wild-type of the offspring cross each other and since the parents have antagonistic phenotypic characters for each gene, all the progeny produced in the F1 is heterozygous with VgvgHh genotype, where
Vg: Normal wings.
eg: Vestigial wings.
H: Body with normal hair.
h: Hairy body.
Once F1 reproduces with each other, the Mendelian proportions 9/16, 3/16, 3/16, 1/16 expected in the F2 generation are produced.
Since in total there were 1024 individuals in the offspring, this amount is multiplied by the expected proportions, giving rise to the mentioned result.
High temperatures and greater rainfall increase the rate of chemical weathering. 2. Rocks in tropical regions exposed to abundant rainfall and hot temperatures weather much faster than similar rocks residing in cold, dry regions. ... Soils affect the rate in which a rock weathers.
