Answer:
some molecules pass
Explanation:
The ability of a membrane to pass or not to pass a substance is its permeability (permeability).
Permeability is, in fact, the ease with which a dissolved particle passes through the membrane, which depends on both the properties of the particles and the properties of the membrane itself.
The membrane is semipermeable (semipermeable) or selectively permeable because it does not permeate all molecules.
- <em>The cytoskeleton is the network of fibres forming the eukaryotic cells, prokaryotic cells and archaeans. </em>
Explanation:
- <em>It provides shape and support to the cell, organizes the organelles and facilitates transport of molecules, cell division and cell </em><em>signalling</em>

Answer:
Yes, P. Falciparum and T. Cruzi undergo similar antigenic variation because of repetitive genomes evolved by time.
Explanation:
Living (i.e., actively proliferating) repeats are dynamic elements which reshape their host genomes by generating rearrangements, creating and destroying genes, shuffling existing genes, and modulating patterns of expression. Dead repeats (i.e., those which are no longer able to proliferate) constitute a palaeontological record, which can be mined for clues about evolutionary events and impetus. The dynamic nature of repeats leads to a rapid evolutionary divergence that can be used in species identification and phylogenetic inference. Repeats can also provide passive markers for studying processes of mutation and selection.
The genomes of these protozoan parasites, like all eukaryotic genomes, have been colonized by diverse repetitive elements. Repetitive sequences can be artificially divided into two groups: interspersed repeats and tandemly repeated DNA. P. falciparum undergoes antigenic variation ans similar anitgenic variation is present in t. cruzi because of repetitive sequences resembling each other.
It would be called the seed coat
