Answer:
Those species that are more vulnerable to extinction are the big-sized ones, that reach their sexual maturity in a relatively advanced stage of their lives and have a low growth rate per capita. They have a low reproductive rate.
Explanation:
There are specific heritable traits such as reproductive rate, trophic level, dispersion capability, that influence different species and their trend to be more or less vulnerable to extinction. "k" species have a low growth rate per capita, but they are big competitors with the capacity of displacing other species and monopolizing the available resources. These are big-sized species that live for a long time, reaching sexual maturity in advanced stages of their lives. They do not have numerous progenies, and hence, they spend a lot of time in parenting. Any environmental disturbance seems to severely affect them. These animals have a higher risk of getting extinct than those species with short-lived and elevated reproductive rates.
For many mammals and birds, this is a linear relationship. The bigger is the species, the more prone to get extinct it is.
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.

More than 150 years ago, inventors began working on a bright idea that would have a dramatic impact on how we use energy in our homes and offices. This invention changed the way we design buildings, increased the length of the average workday and jumpstarted new businesses. It also led to new energy breakthroughs -- from power plants and electric transmission lines to home appliances and electric motors.
Like all great inventions, the light bulb can’t be credited to one inventor. It was a series of small improvements on the ideas of previous inventors that have led to the light bulbs we use in our homes today.
