The kingdom that contains prokaryotic organisms is: MCQ with Answer and Explanation

Explanation:
The placenta acts as a temporary endocrine gland, secreting hCG (which maintains the corpus luteum), hPL (which alters maternal metabolism for fetal growth), and high levels of estrogen and progesterone (which maintain the uterine lining and suppress further ovulation). Prolactin, however, is primarily secreted by the anterior pituitary gland, although its levels rise significantly during pregnancy to prepare the mammary glands for lactation.

Explanation:
Phagocytosis, or 'cell eating', is a type of endocytosis where the cell membrane engulfs large solid particles, such as bacteria or cellular debris, forming a vesicle called a phagosome. This phagosome then fuses with a lysosome for digestion. It is primarily performed by specialized cells like macrophages and neutrophils.

Explanation:
Genetic engineering (recombinant DNA technology) involves the direct manipulation of an organism's genes using biotechnology to alter its characteristics. Cloning is the process of producing genetically identical copies of a biological entity, such as a gene, cell, or entire organism. Tissue culture (micropropagation) is a technique used to grow plant cells, tissues, or organs in a sterile nutrient medium, allowing for the rapid, large-scale propagation of plants from a small explant. All statements are correct.
