- Question
According to Erikson, the goal of adolescence is to
Options- A. independent identity
- B. explore who they are
- C. both a & b
- D. None of the above
- Correct Answer
- both a & b
ExplanationAccording to psychologist Erik Erikson, Adolescence is the period of life between childhood and adulthood. They go through the psychosocial crisis of identity versus role confusion, which involves exploring who they are as individuals. During this stage, adolescents explore their independence and develop a sense of self i.e independent identity, ego nature.

Correct Answer: Amount of glucose in blood decreases
Explanation:
We know that, when we eat a meal, any carbohydrates we've eaten are broken down into glucose and passed into the bloodstream. This rise in blood glucose causes insulin to be released from the pancreas so glucose can move inside the cells and be used. As glucose moves inside the cells, the amount of glucose in the bloodstream returns to normal and insulin release slows down.
Correct Answer: Complementary base pairing reduce errors
Explanation:
DNA replication is the biological process of producing two identical replicas of DNA from one original DNA molecule. DNA replication occurs in all living organisms acting as the basis for biological inheritance. Complementary base pairing helps prevent errors in DNA replication.
Correct Answer: Phlebotomy is the process of making an incision in a vein with a needle The person who performs that is called as Phlebotomist Given below are tubes color for which test test which one is used is given clearly They are :: Grey-Top Tube - Potassium Oxalate This tube is used primarily for glucose tolerance testing Lavender-Top Tube - EDTA: EDTA is the anticoagulant used for most hematology procedures Its primary use is for the CBC and individual components of the CBC The larger (6ml) tube is used for blood bank procedures Red-Top Tube - This tube has no anticoagulant and is used for many chemistry tests, drug levels, and blood bank procedures Green-Top Tube - Sodium Heparin or Lithium Heparin Navy Blue-Top Tube - There are two general types - one with K2 EDTA and one with no anti-coagulant This tube is used primarily for trace metal analysis Serum Separator Tube (SST®) - This tube contains a clot activator and serum gel separator It has no anticoagulant and is used for many chemistry tests It cannot be used for certain drug levels or any blood bank procedures Yellow-Top Tube - ACD (Sol A or Sol B) Blue-Top Tube - Sodium Citrate (NaCitrate): This tube is primarily used for coagulation studies (PT and PTT) Complete filling of this tube is essential to obtain accurate results
Correct Answer: Liver cells
Explanation:
Body cells that respond to insulin include liver cells and many other cells in the human body.
Correct Answer: progesterone
Explanation:
The principal hormone secreted by the corpus luteum is progesterone. Menstruation is triggered by a drop in the levels of progesterone.
Correct Answer: environmental cues such as the smell or taste of food
Explanation:
Appetite is the desire to eat food, sometimes due to hunger. Appetite is triggered by environmental cues such as the smell or taste of food. Appealing foods can stimulate appetite even when hunger is absent.
Correct Answer: females and expressed by males
Explanation:
Haemophilia is an inherited bleeding disorder where the blood doesn't clot properly. It is caused when blood does not have enough clotting factor.
The main treatment for hemophilia is called replacement therapy. Concentrates of clotting factor VIII (for hemophilia A) or clotting factor IX (for hemophilia B) are slowly dripped or injected into a vein. These infusions help replace the clotting factor that's missing or low.
Correct Answer: Four chromatids
Correct Answer: myelinated axons
Correct Answer: there is breakdown of these regulatory mechanisms leading to formation of benign and malignant tumors
Explanation:
In cancer cells, there is breakdown of these regulatory mechanisms. Normal cells show a property called contact inhibition by virtue of which contact with other cells inhibits their uncontrolled growth. Cancer cells appears to have lost this property. As a result of this, cancerous cells just continue to divide giving rise to masses of cells called tumors. Tumors are of two types: benign and malignant.
