High temperatures and greater rainfall increase the rate of chemical weathering. 2. Rocks in tropical regions exposed to abundant rainfall and hot temperatures weather much faster than similar rocks residing in cold, dry regions. ... Soils affect the rate in which a rock weathers.
Lessen impacts of flooding by absorbing water and reducing the speed at which flood waters flow. Upstream wetlands can serve to store flood waters temporarily and <span>release them slowly downstream.</span>
There are 5 different levels of cellular organization.
Cells, tissues, organs, organ systems and whole organisms. Cells hold genetic material and absorb outside energy.
Tissues make up the bones, nerves and connective fibers of the body. Organs work to perform specific bodily tasks, such as filtering blood. Organ systems are groups of organs that perform a specific kind of function together, such as digesting food.
Together, these smaller systems make up an entire living organism which can grow and then go onto reproduce.
Explanation:
Sympathetic nervous system is activated in this situation.
This branch of nervous system is activated when any individual encounters stressful or dangerous situation.This is responsible for 'fight or flight' response.
It takes place by activating adrenal gland which releases specific hormones adrenaline and nor adrenaline also called as catecholamines . These hormones are responsible for the appropriate physiological response to the situation.
The correct answer is A. Is that which benefits others while causing a disadvantage to the individual.
Explanation:
In biology, altruistic behavior occurs as one organism actions benefit other organisms either because these actions increase the reproductive fitness or the chances an organism survives and prevails over time. Additionally, altruistic behavior implies there is a disadvantage for the organisms acting in the benefit of others. For example, wolves or similar animals take food to those that did not participate in hunting, which means they help other wolves to survive on their own cost as this means less food for those that hunted. According to this, altruistic behavior "is that which benefits others while causing a disadvantage to the individual".
