اس سوال کو وضاحت کے ساتھ پڑھیں
Explanation
Endometriosis is a condition where tissue similar to the lining of the uterus grows outside the uterus.
This tissue can cause pain and infertility, primarily in women.
There is very strong evidence linking endometriosis to female infertility.
Studies show that a significant portion of women with infertility also have endometriosis.
While endometriosis can rarely occur in men, it is not considered a significant cause of infertility in males.
بیضہ دانی سے پہلے کے چند دنوں کے مقابلے میں، بیضہ دانی کے تین دن بعد کون سا ہارمون زیادہ مقدار میں خارج ہوتا ہے؟
FSH
LH
Oestrogen
Progesterone
اس سوال کو وضاحت کے ساتھ پڑھیں
Explanation
After ovulation, the ruptured follicle forms a structure called the corpus luteum, which produces large amounts of progesterone.
This hormone is crucial for preparing the uterine lining for potential pregnancy if fertilization occurs.
مندرجہ ذیل میں سے کون بہتر وضاحت کرتا ہے کہ ہیموفیلیا عورتوں کے مقابلے مردوں میں زیادہ عام کیوں ہے؟
It is caused by a dominant autosomal gene
It is a Y-linked disorder
It is inherited as an X-linked recessive trait
It is more often acquired later in life due to liver disease
اس سوال کو وضاحت کے ساتھ پڑھیں
Explanation
Hemophilia is most often caused by a mutation in a gene on the X chromosome (either the F8 gene for hemophilia A or F9 for hemophilia B).
Males have one X and one Y chromosome (XY), so if their single X chromosome carries the defective gene, they will have hemophilia.
Females have two X chromosomes (XX), so a mutation would have to occur in both copies of the gene for them to show symptoms , which is much less common.
If only one X has the mutation, they are typically carriers.
ویکسینیشن کے بعد طویل مدتی قوت مدافعت فراہم کرنے کے لیے بنیادی طور پر کون سا امیونوگلوبلین ذمہ دار ہے؟
IgA
IgG
IgM
IgE
اس سوال کو وضاحت کے ساتھ پڑھیں
Explanation
Immunoglobulin G (IgG) is the most abundant antibody in the human body.
It plays a crucial role in long-term immunity by recognizing and neutralizing pathogens.
IgG antibodies are produced after exposure to an antigen, such as a vaccine.
They persist in the bloodstream for an extended period, allowing the body to respond to subsequent infections with the same pathogen quickly.
IgG can also cross the placenta, providing passive immunity to newborns.
سیفلیس کا کارآمد حیاتیات کیا ہے؟
Treponema pallidum
Mycoplasma pneumoniae
Neisseria gonorrhoeae
Chlamydia trachomatis
اس سوال کو وضاحت کے ساتھ پڑھیں
Explanation
Treponema pallidum is a spirochete bacterium that causes syphilis.
This is the correct answer as confirmed by multiple sources.
گردے کی ڈائیلاسز مشین میں کونسا مادہ مریض کے خون سے ڈائیلاسز سیال میں نہیں پھیلایا جائے گا؟
Protein
Salts
Urea
Water
اس سوال کو وضاحت کے ساتھ پڑھیں
Explanation
Proteins are indeed large molecules that cannot pass through the pores of a dialysis membrane due to their size,
Allowing dialysis to be used for purification or buffer exchange by separating them from smaller molecules and ions.
انسانی دل میں، دائیں ویںٹرکل کی دیوار دائیں ایٹریم کی دیوار سے موٹی کیوں ہے؟
The right atrium must pump blood all the way around the body
The chambers have different oxygen concentrations
The right ventricle must exert a greater force than the right atrium
The right ventricle receives more blood than the right atrium
اس سوال کو وضاحت کے ساتھ پڑھیں
Explanation
The right ventricle is responsible for pumping deoxygenated blood to the lungs.
While the right atrium receives blood from the vena cava, it only needs to passively push that blood into the right ventricle.
The right ventricle, however, needs to generate significant force to propel the blood through the pulmonary artery to the lungs.
This requires a thicker, more muscular wall.
انسانی گردشی نظام میں، کیپلیریوں سے بافتوں کے سیال میں مواد کی منتقلی کا کیا سبب ہے؟
Active transport
Blood pressure
Capillarity
Osmosis
اس سوال کو وضاحت کے ساتھ پڑھیں
Explanation
The primary force driving the transfer of materials from capillaries t o tissue fluid is blood pressure.
This pressure pushes fluid and solutes out of the capillaries at the arterial end,
Where it is higher, and draws fluid back in at the venous end, where it is lower.
This process is called filtration.
The allele for height has at least two different genes
There are at least two different alleles of the gene for height
There are two different genes for height each having a single allele
There is one allele for height with two different forms.
اس سوال کو وضاحت کے ساتھ پڑھیں
Explanation
The genotype Tt represents two different alleles of the same gene:
T = dominant allele (e.g., tall) t = recessive allele (e.g., short) This means the organism is heterozygous for the height gene — it has two different alleles (T and t) of one gene.
کروموسوم کے بارے میں کون سا بیان درست ہے؟
Genes include long DNA molecules called chromosomes
Chromosomes are long DNA molecules called genes which are divided into sections
Chromosomes include a long molecule of DNA divided into sections called genes
Chromosomes include genes which are divided into sections called DNA molecules
اس سوال کو وضاحت کے ساتھ پڑھیں
Explanation
A chromosome is a long DNA molecule that carries genetic information. Genes are specific segments of DNA on the chromosome that code for proteins or functional RNA.
