You would predict that indoleacetic acid, a plant hormone, would have is a Auxin.
A chemical known as indoleacetic acid (IAA) is produced by plants and a few microorganisms (3, 4). IAA is important for both root and shoot growth in plants. By means of an efflux pump (PIN1-7) and a specified importer (AUX1), the hormone travels from one area of the plant to another (5, 6).
Auxin mainly help in complex mechanism of a plant , which lead many metabolic activities in plant .
What is Auxin ?
- Auxin plays a crucial role in controlling plant growth and development by regulating embryonic development, root and stem tropisms, apical dominance, and the transition to blooming.
- It is used to start off shoot growth in culture and encourages lateral and accidental shoot growth.
- Aids in overcoming auxin-induced apical dominance.
- Encourage the development of leaves' chloroplasts.
- Encourages the mobilization of nutrients and delays leaf senescence.

She should use as large a sample size as possible because she vets more data. S he also repeat this at least twice to get accurate data
Answer:
somatic motor neuron hyperexcitability; inhibition
The neuronal circuitry to skeletal muscles involves neurons that stimulate contractions and those that inhibit contractions. The muscle spindles and Golgi tendon organs are involved in maintaining the proper muscle tonus (resting muscle tension); they work by signaling the CNS. Since tetanus involves SOMATIC MOTOR NEURON HYPEREXCITABILITY, the neurons involved in muscle contraction INHIBITION are affected.
Explanation:
Tetanus is a infection that is caused by a bacteria called Clostridium tetani. It occurs when open wounds in the body are not properly treated and they get infected. This wound can be caused by stepping on a nail or sharp object like broken bottle.
When tetanus enters an open wound present on the body, it attacks the neurons in the body, specifically the somatic motor neurons. Tetanus hinders the release of neurotransmitters and blocks the inhibitory properties of the muscles. These causes the muscles of the body to contract unhindered and uncontrollably resulting in spasms. This can also be referred to as neuronal hyperexcitabilty.
im hispanic but put it in english and then i could help you for sure i promise ill edit my answer and everything solo pongalo en ingles por favor
Answer:
The correct answer is D) There are signs that Mars once had liquid water on its surface.
Explanation:
Researchers have not found life, or evidence of life, on Mars yet. This planet is considered to be a good candidate in the search of extraterrestrial life because, even though it is smaller than the earth, it still is a huge planet with high possibilities of life on it.
There is evidence that more than 3.500 million years ago, Mars was a warmer planet with water on its surface. There are, for example, some dry riverbeds that reflect the presence of rivers on the planet´s surface. They believe that Mars once had an atmosphere with CO², but after losing it, the planet became cold and desertic.
Researchers have found subterranean water, which was detected by radar. There is a lake in the martian south pole, 1.5 km under a thick ice layer, that has at least a meter wide, 20 kilometers long, and is surrounded by high ground. They establish that its origin is the melting of the ice. It is very cold and salty, which makes it difficult to find life on it, but the only ecological niche that could exist for life is underground where there is protection from extreme cold and high radiation levels.
