Biology

Answer:

Biology is the science that studies life, but what exactly is life? This may sound like a silly question with an obvious response, but it is not always easy to define life. For example, a branch of biology called virology studies viruses, which exhibit some of the characteristics of living entities but lack others. It turns out that although viruses can attack living organisms, cause diseases, and even reproduce, they do not meet the criteria that biologists use to define life. Consequently, virologists are not biologists, strictly speaking. Similarly, some biologists study the early molecular evolution that gave rise to life; since the events that preceded life are not biological events, these scientists are also excluded from biology in the strict sense of the term.

Which statement describes potassium-argon dating?

Fiesta28 [93]

Answer: Potassium-40 decays into argon gas over time.

Explanation: Potassium-argon dating is a dating method used to determine the age of sedimentary rocks by comparing the proportion of K-40 to Ar-40 in a sample of rock, and knowing the decay rate of K-40.

Potassium-40 undergoes decay following first order kinetics as given below:

$_{19}^{40}\textrm{K}\rightarrow _{18}^{40}\textrm{Ar}+_{0}^1e$

It is true that epidural bleeding is a. associated with widespread vascular disruption. b. characterized by a lucid interval imm

oksian1 [2.3K]

Answer:

b. characterized by a lucid interval immediately after injury.

Explanation:

Epidural bleeding is the accumulation of blood between the dura (membrane lining the brain) and the skull. This bruise is typically caused by an acute head trauma that ruptures the middle meningeal artery. This bleeding is characterized by a lucid interval immediately after an injury to this region.

This bleeding has its most frequent location at the temporal lobe level, between the bone and the dura mater. It is due to rupture of the middle meningeal artery, usually by a temporal bone fracture. The artery runs on the outer surface of the dura, housed in a groove in the inner bone board. The fracture may clamp or cut the artery, leading to a bruise.

How can local environmental changes have global effects?

Alex777 [14]

Answer:

Explanation:

Water and air circulate around the world in water currents and wind systems (like prevailing winds) respectively, hence distribute energy and whatever else they are carrying across the globe. This is why polluting the oceans in the equatorial region will have indirect consequences for marine life in the poles.

Pollution of air through emission of greenhouse gases in one part of the globe will contribute to global warming across the world because these emissions will be carried around by prevailing winds and diffuse across the atmosphere.

Global warming also causes climate change that subsequently causes the displacement or migration of organisms when this change in climate is unfavorable
