The FedEx of the cell are the vesicles.
Vesicles are the structures in which many cell materials are packed and transported. Vesicles are cellular organelles that are composed of a lipid bilayer and they function as cellular envelopes to transport cell materials from one place to another inside the cell.
An example of one material is protein. After a particular protein has been synthesized in the ribosomes of the cell, it is packaged in a vesicle called a transport vesicle. The vesicle carries this package to the Golgi apparatus for final tweaking after which it is again repacked in a new vesicle which transports it to its required destination in the cell.
<span>Three anatomical features that birds share with their theropod ancestors are:
</span><span>1. they had light, hollow bones
</span>2. they rearranged hip and leg muscles because this of <span>improved bipedal movement
</span>3. they had their flight oriented with the use of wings for balance
An element is also a pure substance. The reason for this is because an element contains only one type of particle.
Option A is correct
The Cross-Linkage Theory or also referred to as the glycosylation theory of aging was discovered or proposed by Johan Bjorksten in the 1940s. According to this theory, the aggregation of cross-linked proteins can damage cells and tissues this slowing down the bodily processes that eventually results to aging. In recent studies, cross-linking is associated with age-related changes in the studied proteins. Furthermore, this theory stresses out that the binding of glucose to proteins can cause various problems. Once the said binding occurs, the protein becomes impaired which leads to its performance inefficiency. Living a longer life would also mean increasing the possibility of oxygen-glucose meeting and protein. Some of the known cross-linking disorders include senile cataract and the appearance of tough, leathery, yellow skin.
