Hasan most likely has rickets
Rickets is a disease of children which is caused by vitamin D deficiency. Rickets softens and weakens bones in affected children. Symptoms of rickets include bowed legs, pain in the bones, stunted growth, trouble sleeping and muscle weakness. Rickets can lead to other health problems such as intellectual disability and muscle spasms.

The answer is "<span>c. Ozone in the troposphere is beneficial to living organisms."
because options a, b and d are true about ozone layer.
</span>
Ozone layer is the area of the upper atmosphere, between around 15 and 35 km over Earth's surface, containing generally high groupings of ozone particles (O₃). Roughly 90 percent of the environment's ozone happens in the stratosphere. The ozone layer successfully squares all sun oriented radiation of wavelengths under 290nm from achieving Earth's surface, including certain kinds of UV and different types of radiation that could harm or kill most living things.
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.
