Answer:

The Sun rotates on its axis once in about 27 days. This rotation was first detected by observing the motion of sunspots. The Sun's rotation axis is tilted by about 7.25 degrees from the axis of the Earth's orbit so we see more of the Sun's north pole in September of each year and more of its south pole in March.

Since the Sun is a ball of gas/plasma, it does not have to rotate rigidly like the solid planets and moons do. In fact, the Sun's equatorial regions rotate faster (taking only about 24 days) than the polar regions (which rotate once in more than 30 days). The source of this "differential rotation" is an area of current research in solar astronomy.

The second messenger in the following G-protein-linked-receptor pathway is signal moleculeG protein linked receptor activated G

melamori03 [73]

Answer:

Answer is D - cAMP.

Explanation:

cAMP is a small molecule that functions as an intracellular signaling molecule - a second messenger. The first messenger would be the thing that activated the GPCR (e.g. a hormone). The GPCR is a signal transducer (converts extracellular signal to intracellular signal). Once activated, the GPCR activates adenylate cyclase which can be called a signal effector - it is an enzyme that produces cAMP.

Consider the following five infectious diseases: Ebola hemorrhagic fever avian influenza SARS West Nile encephalitis mad cow dis

arsen [322]

Answer:

All these are emerging infectious diseases.

Explanation:

The emerging infectious diseases refer to the infections, which have appeared freshly within a population or those whose occurrence or geographic range is enhancing briskly or is threatening to upsurge in the coming time. The emerging infections can be a result of:

1. Known agents, which have dispersed to novel geographic locations or new populations.

2. Previously unknown or undetermined infectious agents.

3. Previously known agents whose function in particular diseases was not determined previously.

According to WHO, infectious diseases are emerging at a rate, which has not been noticed before. Since the 1970s, many infectious diseases have been discovered like Ebola, SARS, avian influenza, mad cow disease, and West Nile encephalitis.

With the individuals traveling much more to far greater distances in comparison to the past, encountering with wild animals, and living in more densely populated regions has caused the emerging infectious diseases to spread briskly and is resulting in global epidemics, which is a major worry.

Explain the role of a hypothesis in a scientific investigation.

k0ka [10]

Answer:

A hypothesis is a testable proposition

used to explain scientific phenomena. It

may be based on previous observations

(a sort of educated guess) or it may

simply be a hunch. Most scientific

hypotheses are combinations of

observation and intuition. The important

thing is that the hypothesis be testable.

If the hypothesis is disproved through

testing, then it is discarded and a new

hypothesis is proposed. If the hypothesis

stands up to rigorous testing, then our

faith in the hypothesis is increased.

This system of careful, rigorous, and

unbiased testing of a hypothesis is what

characterizes the scientific method.

Hope it helps!
