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.
Irina's claim is not found here but evidence from an experiment might include the amount of a product (chemical) or the order of nucleotides (biological evidence).
<h3>What is scientific evidence?</h3>
Scientific evidence refers to the observations that can be used to support (or reject) a working hypothesis.
Scientific evidence is variable depending on the field but it is always collected by observational or experimental procedures.
In conclusion, Irina's claim is not found here but evidence from an experiment might include the amount of a product (chemical evidence) or the order of nucleotides (biological evidence).

Answer:
Chloroplast
Explanation:
Chloroplasts are organelles found in green plants. They are the sites of photosynthesis. Chloroplasts contain chlorophyll, a photosynthetic pigment that traps light energy. This energy is used to power a series of reactions that convert water and carbon dioxide into sugars.
Answer:
Only one chromosome from each pair randomly passed to the s*x cells during meiosis and leads to differences between the siblings.
Chloroplasts are the organelles that contain the chlorophyll pigment, which is essential for the good-making process of photosynthesis.
