At what age does dendrite growth appear to stop?

User Avatar

Asked by Wiki User

Dendrite growth in the brain is thought to start to slow down in adulthood, around the age of 20-25. While some new connections can still form, the rate of dendrite growth decreases significantly compared to childhood and adolescence.

Explain how calcitonin and triiodothyroninne work together to meet the genetically determined maximum height at which an individual will grow during a growth spurt?

User Avatar

Asked by LajuanHance

Calcitonin and triiodothyronine are hormones that regulate bone growth. Calcitonin lowers blood calcium levels by inhibiting bone breakdown, while triiodothyronine stimulates bone growth. Together, they help maintain proper bone density and growth during a growth spurt, keeping the individual within their genetically determined maximum height potential.

What is the average year-to-year conditions of the atmosphere in an area called?

User Avatar

Asked by Wiki User

The average year-to-year conditions of the atmosphere in an area are referred to as climate. Climate encompasses various factors such as temperature, humidity, precipitation, and wind patterns that are observed over an extended period, typically 30 years or more.

When does a polypeptide stop growing?

User Avatar

Asked by Wiki User

A polypeptide stops growing when the ribosome reaches a stop codon on the mRNA template. This triggers the release of the polypeptide chain, along with the ribosome and mRNA, from the protein synthesis machinery.

Why do peoples bones stop growing at the age of 20?

User Avatar

Asked by Wiki User

Bone growth is controlled by a variety of factors, including growth plates found at the ends of long bones. At around age 20, these growth plates ossify and turn into solid bone, which signals the end of longitudinal bone growth. After this point, bone remodeling and maintenance occur instead of growth.

How is a growth rate related to a growth factor?

User Avatar

Asked by Wiki User

A growth factor is a numerical value that quantifies the increase or decrease of a quantity over time, while a growth rate is the percentage change in that quantity over a specific period. The growth factor is derived from the growth rate by adding 1 to the growth rate percentage expressed as a decimal. For example, a growth rate of 5% corresponds to a growth factor of 1.05.

How much blood can a 12 year old girl lose from her period without dying?

User Avatar

Asked by Wiki User

On average, a 12 year old girl may lose up to 1.5 ounces (45 ml) of blood during her period. Excessive blood loss can be dangerous and potentially life-threatening, but the body has mechanisms to regulate and replace lost blood. If a girl is experiencing heavy bleeding, it is important to seek medical attention.

What feature of life is illustrated by that boy shot up five inches in only one year?

User Avatar

Asked by Wiki User

The rapid growth in height of the boy illustrates the biological process of growth and development during adolescence. During this period, young individuals undergo significant physical changes and growth spurts as they transition from childhood to adulthood.

Do organs stop growing?

User Avatar

Asked by Wiki User

Yes, most organs stop growing once an individual reaches adulthood. However, some organs can regenerate and repair themselves throughout life, such as the liver and the skin.

What organ regulates breathing rate?

User Avatar

Asked by Wiki User

The brainstem, particularly the medulla oblongata, regulates the breathing rate by monitoring levels of carbon dioxide and pH in the blood. This area helps control the diaphragm and intercostal muscles to adjust breathing in response to the body's needs.

When is the exact time our body parts stop growing?

User Avatar

Asked by Wiki User

Body parts reach their maximum size during different stages of development. For example, the brain stops growing in early adulthood, while bones typically stop growing in length by the late teens. However, muscle mass can continue to increase with exercise and nutrition even into adulthood.

Why does a testicle of a 10 year old retract inside the body?

User Avatar

Asked by Wiki User

The retraction of a testicle in a 10-year-old boy can be a normal response to cold or fear due to the cremasteric reflex, which helps regulate the temperature of the testicles. It can also happen during periods of physical activity or excitement. If the retracting is persistent or associated with pain, a medical evaluation is recommended.

How does the rate of extinction compare to the rate of species formation on earth today?

User Avatar

Asked by Wiki User

Currently, the rate of extinction is significantly higher than the rate of species formation on Earth. Human activities, such as habitat destruction, climate change, and pollution, have accelerated the extinction rate. This imbalance in the rates of extinction and species formation is leading to a loss of biodiversity at an alarming rate.

What could stop your penis growing?

User Avatar

Asked by Wiki User

Factors that could potentially hinder penis growth include genetic predisposition, hormonal imbalances, and certain medical conditions that impact development. Additionally, lifestyle factors such as poor nutrition or drug use may also play a role in stunting penis growth. It's important to consult with a healthcare provider for a proper evaluation and treatment if concerned.

How do you calculate subsidence rates?

User Avatar

Asked by Wiki User

Subsidence rates can be calculated by measuring changes in elevation over a specific period of time. This can be done using techniques such as GPS surveys, satellite imagery, or leveling surveys. By comparing the initial elevation data to the current elevation data, the rate of subsidence can be determined.

Why is a 10 million year old tree not made of wood?

User Avatar

Asked by Wiki User

A 10 million year old tree may not be made of wood because wood is composed of dead cells that have undergone lignification, a process that occurs in living trees. Over time, these cells can decay or be replaced by other materials, leading to the loss of wood-like characteristics.

Why dont all people grow at the same time and at the same age?

User Avatar

Asked by Wiki User

People grow at different rates and ages due to genetic factors, differences in hormone levels, and variations in nutrition and overall health. Growth spurts are also influenced by individual differences in puberty onset, which can occur earlier or later for each person. This variability results in people reaching their full height at different ages.

What age does the male brain stop devloping?

What is an uncontrolled growth and spread of abnormal cells?

User Avatar

Asked by Wiki User

An uncontrolled growth and spread of abnormal cells is known as cancer. This occurs when cells divide uncontrollably and can invade surrounding tissues, leading to the formation of tumors and potential harm to the body. Cancer can arise from various factors, including genetic mutations, environmental exposures, and lifestyle choices.

What is a growth sprout?

How does salt affect the growth of seeds?

User Avatar

Asked by Wiki User

Excessive salt in the soil can inhibit seed germination and plant growth by disrupting water uptake and nutrient absorption. Salt can also cause osmotic stress, leading to dehydration and damage to plant cells. Additionally, high levels of salt can alter the soil's pH, further hindering seedling growth.
