Why do sunspots appear as dark spots on the surface of the Sun?
Answers
Answer:
I think it is because the sun has released energy and looses light in that area because of it.
Explanation:
Answer: Sunspots are "dark" because they are cooler than their surroundings. ... Sunspots have a lighter outer section called the penumbra, and a darker central region named the umbra. Sunspots are caused by disturbances in the Sun's magnetic field welling up to the photosphere, the Sun's visible "surface".

You are a red blood cell in the LEFT VENTRICLE of the heart. In the correct sequence, which blood vessels must you pass through in order to get down to the RIGHT wrist (the palmar arches)?
Answers
The correct sequence of blood vessels that must be passed to get to the Right wrist is :
From the Left ventricle --> Aorta ------> Brachiocephalic artery ------> Right subclavian artery -----> Right axillary artery -----> Right brachial artery-------> Right ulnar and radial arteries -----> Right wrist .The Aorta is the first passage( blood vessel) of the oxygenated blood, pumped out of the left ventricle of the heart, It forms an arch through which other arteries like Brachiocephalic artery originates to distribute blood to the upper parts.
The right subclavian, axillary and brachial all supply blood to the right arm while the Right brachial artery further divides into Right Ulnar and radial arteries.
Hence we can conclude that The correct sequence of blood vessels that must be passed to get to the Right wrist is :
From the Left ventricle --> Aorta ------> Brachiocephalic artery ------> Right subclavian artery -----> Right axillary artery -----> Right brachial artery-------> Right ulnar and radial arteries -----> Right wrist .

Definition Of polar molecules and nonpolar molecules please?
Answers
Answer:
Non polar molecules are symmetric with no unshared electrons. Polar molecules are asymmetric, either containing lone pairs of electrons on a central atom or having atoms with different electronegativities bonded.
Explanation:
When things are different at each end, we call them polar. Some molecules have positive and negative ends too, and when they do, we call them polar. If they don't, we call them non-polar. Things that are polar can attract and repel each other (opposite charges attract, alike charges repel).

If an invasive species emigrated from a continent to a small island near the continent, what would most likely occur on the island
Answers
Answer:
Organisms on the island would migrate to a larger island.
Invasive species can cause extinctions, reduce biodiversity, compete for resources, and modify environments.
What is an invasive species?An invasive species is a category of non-native species that has overtaken the habitat to which it was initially introduced.
Native plants and animals may go extinct as a result of invasive species, which can also decrease biodiversity, compete with native species for scarce resources, and disrupt habitats.
Preventative measures are the most practical and secure method of managing invasive species. It is far more effective to deal with invasive species early on and quickly than to try and contain an extensive infestation. The invasive species may be the target of control and management measures if eradication is not achievable.
