Answer:
Achondroplasia affects the long bones and individual has normal size, head and torso.
Explanation:
Achondroplasia dwarfism may be defined as the form of dwarfism in which the conversion of bone to cartilage is defected. This is the most common form of dwarfism.
Achondroplasia dwarfism mainly affects the long bones of an individual as there is problem in the conversion of cartilage to bone. The individuals have short arms and legs but they have normal head and torso size. The individuals has height around 4 feet.
Answer;
-Scaffolding
Explanation;
Scaffolding as a metaphor in teaching and learning describes the adaptive and temporary support provided by a more competent person (e.g., teacher or adult) to a less competent person (e.g., student or child). For example; mother–child interaction during the game of peekaboo.
Scaffolding is one of the several aspects of effective instruction that can be applied in the context of language learning. Although teachers might be enthusiastic about the idea of scaffolding, it must be borne in mind that scaffolding is not simply synonymous with teacher support.
Answer:
The exoskeleton helps support movement by working with the muscles.
Explanation:
Answer:
B. Both mussels and barnacles live in the tidal ecosystems.
Explanation:
Mussels are <u>small bivalve molluscs that are adapted to both marine and freshwater ecosystems</u>. Barnacles, on the other hand, <u>are arthropods that are adapted to marine ecosystems. However, both are adapted to shallow and </u><u>tidal</u><u> zones</u>.
Both organisms are small and have the capacity to live in tidal ecosystems where they thrive and play important ecological roles. For instance, barnacles are filtering organisms, which is extremely important for the food chain, and mussels filter out significant amounts of excess nutrients and metals, that is, they make the water more suitable and clean for organisms to live.
As they are both adapted to tidal ecosystems, this would be an example of an adaptation that allows similar species, in this case mussels and barnacles, to live in the same environment.
Answer:
Elastic fibers are made of elastin and microfibrils, that are elastic protein structures. The proteins can be stretched and resume normal shape. These fibers are found in parts of the body such as arteries, skin, lungs, connective tissue and heart that require some stretching. Marfan syndrome affects the elastic connective tissues causing symptoms like dilation of the aorta that doesn't resume normal lumen diameter (aortic aneurysm), and curving of the spine (scoliosis).
The lungs are unable to stretch and resume shape normally and this affects the respiratory system. The subjects will suffer from shortness of breath, wheezing and chest pain.
The sheath/endoneurium of neurons is connective tissue. This part of a neuron allows signals to travel effeciently along the axon of the neuron. This means that a person with Mafran syndrome has a slower response to stimuli that ordinary persons.
