What else can I help you with?
Which of these terms can be defined as a root's downward growth as a response to gravity?
geotropism
What is the definition of chemotropism and what exhibits it?
Movement or growth of an organism or part of an organism in response to a chemical stimulus.
What is the difference between positive and negitve geotropism?
Geotropism (also called gravitropism) is the turning or growth movement by a plant or fungus in response to gravity. Roots show positive geotropism (grow toward gravity - down) and stems show negative geotropism (grow away from gravity - up).
What is a disorder in which cells lose the ability to control their growth rate?
Cancer is the disorder that causes someone's own cells in their body to lose the ability to control growth.
What problems does salinity cause to the environment?
salt absorbs moisture from the ground this prevents plant growth also salt crystals are sharp and damage tender growth this causes erotion.
What are the potential issues that can arise when there is no space between deck boards?
When there is no space between deck boards, potential issues can arise such as water pooling, increased risk of rot and decay, limited airflow which can lead to mold and mildew growth, and difficulty in cleaning and maintenance.
What is plant growth in response to touch?
Plant growth in response to touch is called thigmotropism.
Describe the difference between a response and a tropism?
A response is a reaction or behavior of an organism to a stimulus in its environment, while a tropism is a specific growth response of a plant to a stimulus, such as light or gravity. Responses are more generalized and can involve various reactions, while tropisms are specific and directed growth movements.
What is the stimulus that causes growth hormone to be released?
Growth hormone is primarily released in response to low blood glucose levels, stress, exercise, sleep, and certain amino acids. Growth hormone-releasing hormone (GHRH) from the hypothalamus stimulates the pituitary gland to release growth hormone in response to these stimuli.
What are the distinctions between economic growth and economic development?
Economic growth is the growth of people which causes economic development, the growth/development of cities/towns. (i.e. businesses and buildings)
What is growth in response to growth called?
thigmotropism
What do you call a plant response?
Phototropism, where the plant "turns" to arrange its leaves for better exposure to light. This process is regulated by growth regulators in the plant. Photo = light Tropism from the Greek "trope" or turning. See picture
What is a factor that causes a response in plants?
Because plants were designed too be effient, and they will make minor changes to promote efficiency
What is plant growth in response to growth called?
thigmotropism
When cell signaling causes a response in the nucleus what happens?
When cell signaling causes a response in the nucleus, transcription factors are activated. These transcription factors then enter the nucleus and bind to specific DNA sequences, leading to the regulation of gene expression. This can result in the production of specific proteins that mediate the cellular response to the initial signaling event.
What is the answer to growth in response to a stimulus?
The growth in response to a stimulus is called tropism. Tropisms are directional growth responses exhibited by plants or organisms in response to specific environmental cues such as light, gravity, or touch. These growth responses help the organism to adapt and survive in its environment.
What is the difference between tropism to taxes?
Taxis is a directional response to a stimulus, where the organism moves towards or away from the stimulus. Tropism is a growth response in plants to a stimulus, such as light or gravity, which involves changes in the direction of growth. Essentially, taxis involves movement, while tropism involves growth.
