An organ is:
A. a small structure within a cell. b. a structure composed of several tissue types. c. the basic structural unit of all living organisms. d. a group of organs with a common set of functions. e. a group of cells with similar structure and function
Answer:
b. a structure composed of several tissue types.
Explanation:
There are several levels of organization of life in living things, which progresses from simple structural level to more complex ones. The cell is the basic unit of life capable of carrying out virtually all life’s functions. Cells are composed of several structures known as organelles. Similar cells with similar functions associate to form a tissue at the tissue level. The next level of organization is organ level. Several tissues associate together to form an organ. An example of an organ is the liver. Several organs can as well associate together to form the organ system at the system level of organization.
Although earthquakes often occur before a volcanic eruption, they are not the cause. The earthquakes are the result of magma (molten rock) moving underground leading up to an eruption. A few volcanic eruptions are thought to have been triggered or initiated by earthquakes, but this is not the typical case.
Answer: Factors that affect physical growth and developments are;
1. Sex: sex of a person can affect physical growth and development. It is said that male tend to mature easily.
2. Nutrition. Bad nutrition can affect growth. When a person consume unbalanced and appropriate diets frequently, it will affect his development and growth.
3. Heredity: this is the transfer of genes from parent to offsprings. The type of genes or physical characteristics transmitted by parent to offsprings will determine the offsprings level of growth and development.
4. Hormones: if hormones necessary for growth and development are not secreted in the required amount, it can affect growth and development.
5. Environment: The environment we find ourselve determine our level of development.
6. Exercises and health: If you don't exercise daily, muscle development might not be visible and poor health after growth.
Explanation:
Growth is the increase in size of an individual.
Development is the increase in functionality and individuals ability . There are four stages of growth, infancy, childhood, adolescence and adulthood. Growth and development can be affected by several factors.
Lipases liberate the triglycerides into fatty acids is the process which makes lipids accessible for the digestion.
Explanation:
The triglyceride and other lipids of small intestine are delivered to in the bile for digestion. The molecules of triglyceride get digest ready by enzymes to degrade fatty acids and monoglyceride to transport it to the enterocyte. The process is executed by the lipase and bile acids.
The water soluble enzyme lipase initiates the emulsification process of lipids. It works on the droplets of the surface of triglyeride and liberates the fatty acids along with the monoglyceride retaining its connection with bile acids and other lipids to create micelles structures.
