B is the answer I guess for the question
I dont think it is symbiotic, it is parasitic relationship. They get blood supply of human and dont give anything useful to humans
Seedless vascular plants are classified into three phyla namely the club mosses, horsetails and ferns. Ferns form the numerous seedless plants with true vascular tissue, creeping underground stems called the rhizomes and large leaves called the fronds. They reproduce via spores.
Ferns crowd on the forest floors even after cutting them down. They invade the cleared zone of forest which has been cut for timber via numerous spores. The spores are in clusters called sori on the underside of the leaves. The spores develop into haploid gametophytes by mitosis. They also grow by spreading their rhizomes or from the tips of their fronds.
Ans.
Meiosis involves a type of cell division in sexually reproducing organisms that results in formation of four daughter cells from a single parent cell, having half of the genetic material as in parent cell. Meiosis is divided into meiosis I and meiosis II.
In gamete forming cells of humans are diploid cells and have 23 pairs of chromosomes (or 46 chromosomes). Each gamete forming mother cell undergoes meiotic division to form haploid daughter cells or gametes, each with 23 chromosomes.
Thus, the correct answer is 'twenty-three' as there are 23 chromosomes present in human sex cells at the end of meiosis II.
A laboratory report form should indicate when a specimen has been collected by capillary puncture because certain test outcomes change depending on the specimen source.
<h3>What is capillary puncture?</h3>
For certain tests that call for small amounts of blood, people of any age may undergo capillary puncture or capillary sampling from a finger, heel, or (rarely) an ear lobe. The procedure is, nonetheless, frequently utilized on pediatric patients. For capillary testing on an adult patient, the finger is typically the first choice. Heel's sides are only used in young and neonatal patients. In surveys or research projects, ear lobes are occasionally employed.
