Answer: White Oak
White oak comprises 15% of the commercially available hardwoods in the US. It is a used for structural timbers, flooring, and furniture because<span> of its length (rees average approximately 70 to 80 feet in height), color (White with creamy sapwood and dark gray-brown heartwood) and texture (very strong and hard, and with good steam bending properties). It takes a good finish when machined, nailed and screwed well. </span>
The Linnaean system added more stories onto hierarchy the of complicatedness that Aristotle developed.
The Linnaean system of type of taxonomy was developed by Swedish naturalist named Carolus Linnaeus in the mid 1700. He created a way to organize and name species. He based his type on physical traits of organisms and uses binomial nomenclature to identify organisms. The seven main level of classification are kingdom, phylum, class, order, family, genus and species.
<h3>Why is the Linnaean system important?</h3>
The Linnaean system is critical because it led to the use of binomial nomenclature to recognize each species. Once the system was assumed, scientists could communicate without the use of deceiving common names. A human being became a partner of Homo sapiens, no matter what terminology a person spoke.

Smart home technology is the general term given to basic home amenities that have been fitted with communication technology, enabling some degree of either automation or remote control. It includes things like Home security systems. Environmental controls, like air conditioning, heating, and lighting.
Explanation:
Environmental controls, like air conditioning, heating, and lighting.A spectrometer is a device for measuring wavelengths of light over a wide range of the electromagnetic spectrum. It is widely used for spectroscopic analysis of sample materials. The incident light from the light source can be transmitted, absorbed or reflected through the sample The solution for space exploration is through using mass spectrometers which are used to identify miniature particles present in space. Mass spectrometers are also used in radioactive and carbon dating. When used with gas chronographs, mass spectrometers detect traces of toxic particles and contaminants in air.
Calcium levels in the body are maintained by hormones. If the blood calcium level rises above a set point, calcitonin is secreted by the thyroid gland and sets into motion responses to lower the blood calcium back to the set point. If the blood calcium level falls below a set point, the parathyroid gland secretes parathyroid hormone that sets into motion responses to raise the blood calcium. These homeostatic responses are examples of:
a. positive feedback
b. effectors
c. sensors
d. negative feedback
Answer:
d. negative feedback
Explanation:
Negative feedback responses are the ones that counteract the change. Any alterations in the internal body conditions such as blood calcium levels are sensed by receptors. The information is sent to the brain which in turn commands the effectors such as endocrine glands to secrete the required hormones to restore the normal conditions. Here, changes in the calcium levels are counteracted by the secretion of calcitonin and parathyroid hormones and the calcium is maintained within a narrow range. This represents negative feedback.
The sneezing is release of air that helps the body to get rid of irritants in our nose and throat, like allergens, dirt, and dust.
Coughing is by forcing the air out of the lungs with high pressure, to clear the throat of these foreign particles.
