The United States had the highest rate of obesity in the world, because ONE THIRD of its population is obese.
Obesity is a condition that is associated with having excess accumulated body fat, which can be deleterious to one's health. An individual is considered to be obese if the person's body weight is at least 20% more than it ought to be. Scientifically, obesity has been identified as the major cause of many chronic diseases such as diabetes mellitus, cardiovascular diseases, etc.
Answer:
antibodies are produced in response to infection and that these antibodies are designed to specifically target particular antigens and bind tightly to them.
That is true. Active transport goes against the concentration gradient. Particles want to move from higher concentration to lower concentration and even out, but active transport makes them move against that.
Type of symmetry in which body parts are arranged in a circle around a central point is called radial symmetry.

This type of symmetry is characteristic for the sessile animals like Cnidaria and Echinodermata. Organisms with radial symmetry have no left or right sides, they have a top and a bottom surface, or a front and a back.</span>
Answer:
Granulosa cells
Explanation:
Foliculogenesis is a dynamic and complex process through which the follicle goes through many stages of development in a short period (approximately 60 days in humans and some chimpanzees).
The stages classification is based on morphological changes such as follicular size or diameter, the number of follicular cell layers, etcetera. These classifications might vary among authors but could be denominated as:
- De Graaf follicles (This is the one shown in the image)
Through each stage, there are certain modifications in the oocyte, follicular cells, and connective tissue. As the oocyte grows, the follicular cells might reach a size twice or three times bigger than the ones of the primordial follicles. Their shape also changes and they adopt an aspect of stratified epithelium. Their cytoplasm gets a granulous aspect, after what these cells receive the name of <u><em>granulous cells</em></u>. The De Graaf follicle characterizes for having a space named follicular antro that displaces the oocyte to one of the sides.
The oocyte at this point gets surrounded by <u>zona pellucida</u> and <u>corona radiata </u>.
The follicular antro (The highlighted structure) separates the oocyte from the externally located <u>granulosa cells</u> or follicular cells.
