Answer:
The question lacks options, the options are:
A). the body cell has 2n; the sex cell has 1n.
B). the body cell has 26; the sex cell has two.
C). the body cell has 1n; the sex cell has 2n.
D). the body cell has 24; the sex cell has 26
The answer is A
Explanation:
According to the question, the snapping turtle possesses 52 chromosomes in its cell. This means that the chromosomal number of its body cell is 52. However, the turtle, which reproduces sexually will produce gametes or sex cells via meiosis. Meiosis is the kind of cell division that results in daughter cells (gametes) that have a reduced number of chromosomes (by half).
Based on this, the diploid cells (2n) of the turtle with chromosome number 52 will undergo meiotic division to produce haploid gametes or sex cells (n) with chromosome number 26.
N.B: Diploid (2n) means two complete sets of chromosomes while haploid (1n) means one complete set of chromosome.
The body cell of the turtle contains two set of chromosomes received from each parent, hence, making it Diploid (2n). However, meiosis will reduce the chromosome number to one set in each gamete i.e. haploid (n).

1. A sensory organ is made up of receptors that are made up of cells or a group of cells that can detect external stimuli such as touch, light, sound and others.
<span>In short, water and oil don't mix because they are two substances with different types of molecules. The structure of oil's molecules makes it hydrophobic, so it won't mix with water's molecules. Water is a polar molecule, meaning the amount of electrons in the hydrogen and electronegative oxygen is unequal....</span>
Answer: I think its A
Explanation: Infectious myositis may be caused by a broad range of bacterial, fungal, parasitic, and viral agents. Infectious myositis is overall uncommon given the relative resistance of the musculature to infection. For example, inciting events, including trauma, surgery, or the presence of foreign bodies or devitalized tissue, are often present in cases of bacterial myositis. Bacterial causes are categorized by clinical presentation, anatomic location, and causative organisms into the categories of pyomyositis, psoas abscess, Staphylococcus aureus myositis, group A streptococcal necrotizing myositis, group B streptococcal myositis, clostridial gas gangrene, and nonclostridial myositis. Fungal myositis is rare and usually occurs among immunocompromised hosts. Parasitic myositis is most commonly a result of trichinosis or cystericercosis, but other protozoa or helminths may be involved. A parasitic cause of myositis is suggested by the travel history and presence of eosinophilia. Viruses may cause diffuse muscle involvement with clinical manifestations, such as benign acute myositis (most commonly due to influenza virus), pleurodynia (coxsackievirus B), acute rhabdomyolysis, or an immune-mediated polymyositis. The diagnosis of myositis is suggested by the clinical picture and radiologic imaging, and the etiologic agent is confirmed by microbiologic or serologic testing. Therapy is based on the clinical presentation and the underlying pathogen.
