Genes, diet, environmental factors all affect human growth and development. Also living conditions can also affect ones development.
Parenting styles have a tremendous impact on human growth and development. Authoritative parenting style makes the child responsible, encourages autonomy and independence.

- Heredity: our the genes we received from our parents are the most important factor the influences our growth and development. For instance there is a relationship to the height of a child and the heights of his parents. If you have tall parents, you are more likely to be taller than the average as an adults. Intelligence is another important growth factor. Low grade intelligence is associated with retardation, slow learng and poor performance. On the other hand, high grade intelligence is associated with acceleration, quick learning and excellent performance.Sex is also important, boys are slightly bigger then girls. But when the process of growth sets in after birth, girls exhibit rapid growth and attain full size earlier than boys.
- External factors (nutrition and general lifestyle): Much of the physical growth depends partly upon such environmental factors as sunlight, fresh air, conditions of climate and partly' upon food and nutrition. A well-balanced diet has a positive effect on the growth and development of a child. A balanced diet should include all essential nutrients like carbs, protein, fats, vitamins and minerals.
- Hormones: most of the hormones are involved in growth and development but some of them have a very special role when it comes to growth and development.
- Growth hormone: made by the pituitary gland, released in the bloodstream to travel to body tissue. It stimulates the production of insulin-like growth factor I, or IGF-I.
- Thyroid hormone or thyroxine: produced in the thyroid gland, plays an important role in the growth and development of the brain and affects metabolism.
- Androgens (like testosterone): male-type sex hormones made by the adrenal gland or testes, in girls produced in small amounts in the ovaries. Those hormones trigger the growth of hair in the armpits and genital regions of both boys and girls at puberty. Testosterone in particular is important for the sexual development and maturation of boys.
- Estrogens: the female-type sex hormones made by the ovaries and are responsible to trigger breast development and the sexual maturation process that results in menstrual periods; smaller amounts are made by the testes in boys.
- Cortisol: produced in the adrenal gland and helps to maintain a normal blood pressure and blood glucose levels. Cortisol is released into the bloodstream at higher levels in response to physical stresses such as infection, fever, injury, surgery, and also severe emotional stress.
- Insulin: produced by the pancreas, helps the body to use sugars and starches (carbs) for energy. Balances the blood sugar level.

What are the factors that influence growth and development in humans?
There are 8 main factors that influence the growth and development of every human being. These factors include heredity, environment, sex, nutrition, race, exercise, learning and reinforcement, as well as hormones.
What Factors affect growth rate in humans?
genes definitely play a big factor in human growth. like for example, if you came from a line of tall people, in most likelihood, you will become tall, too. if you came from a family of obese people, most probably you will become fat, too... other factors to consider is your lifestyle and the environment where you live
What changes take place in growth?
During growth, changes such as increases in body size, development of new cells, tissues, and organs, and maturation of physiological functions occur. Hormonal and nutritional factors play a large role in regulating growth processes in both humans and animals. Genetic factors also influence growth patterns.
What are the growth requirements for humans?
Humans need a healthy and a well balanced diet. They need proteins for growth and development. A lot of water is needed and also milk for good bone development. Answered By: Yazmin Lauralai
What factors affect gas exchange in humans?
The factors that affect gas exchange in humans include the amount of gases in the atmosphere. It also includes temperature, atmospheric pressure and ion concentrations.
The universal patterns of the human growth sequence can be attributed to?
The universal patterns of the human growth sequence can be attributed to a combination of genetic factors, environmental influences, and evolutionary processes. These factors interact to shape the typical trajectory of physical, cognitive, and social development that humans experience from infancy to adulthood.
The development of humans was directly dependent on?
The development of humans was directly dependent on factors such as evolution, adaptation to changing environments, use of tools, development of social structures, and increased brain size and cognitive abilities. These factors contributed to our survival and success as a species.
When does development in humans stop?
Development in humans is a lifelong process, but physical development generally stops in the early to mid-twenties when growth plates close and brain development stabilizes. However, emotional, social, and cognitive development continue throughout adulthood.
Explain the satement physical growth follows a general predictable pattern?
Physical growth in humans follows a general predictable pattern known as the growth curve, with periods of rapid growth in infancy, childhood, and puberty followed by slower growth in adulthood. This pattern is influenced by genetic factors and environmental factors such as nutrition, health, and exercise. While there may be variations in individual growth rates, the overall trend of growth and development is generally consistent for most people.
Why are some people more hirsute than others?
Genetics play a significant role in determining the level of hair growth on a person's body. Hormonal factors, such as levels of testosterone, also influence hair growth. Additionally, environmental factors and certain medical conditions can affect hair growth patterns.
How do humans affect the biosphere?
Humans affect the biosphere in numerous ways. One of the most common ways in which humans impact the biosphere is by their extraction of Natural Resources. Growth and expansion is another way in which humans affect the biosphere.
Which of the following abiotic factors would likely affect humans directly?
Climate change
