How do scientists learn about the age of the solar system and its planetary bodies? Select the two correct answers.
a. comparing the composition of the gaseous planets to the rocky planets
b. using radiometric dating of meteorites
c. measuring distances between planets
d. analyzing impact craters on planetary body surfaces
Answer: B, C
Explanation: Scientists use radiometric dating of meteorites and analyze the impact craters on planetary body surfaces to learn about the age of the solar system and its planetary bodies.
Using radiometric dating of meteorites and analyzing impact craters on planetary body surfaces are the two methods that tells us about the age of solar system.
The age of solar system and its planetary bodies can be find out by using radioactive dating techniques. Scientists have find out that the Solar System is 4.6 billion years old due to this technique. The other way to find out the age of solar system and its planetary bodies by counting the number of impact craters occurs on planetary body surfaces so these two methods provides information about the age of solar system and its planetary bodies

How is a polar molecule different from a nonpolar molecule?
A.polar molecules have charges separated like poles of a magnet.
B. Polar molecules have charges evenly distributed across their poles.
C. Polar molecules are attracted to the lipids of the phospholipids of the plasma membrane.
D. Polar molecules are always larger than nonpolar molecules.
Answer: I think its b
Explanation:
if not a
A polar molecule is different from a nonpolar molecule in the fact that a polar molecule has charges separated like the poles of a magnet. Thus, the correct option for this question is A.
What is a Polar molecule?A polar molecule may be defined as a type of molecule in which one end of the molecule is slightly positive, while the other end is slightly negative. For example, water is an example of a polar molecule.
Being a polar molecule, water is separated by a positively charged hydrogen atom and a negatively charged oxygen atom. Polar molecules are asymmetric in nature and significantly contain lone pairs of electrons on a central atom or atoms with different electronegativities bonded together.
Non-polar molecules are symmetric with no unshared electrons. These molecules have resulted from an unequal distribution of electron density.
Therefore, polar molecules have charges separated like the poles of a magnet. Thus, the correct option for this question is A.

In starches the glucose units are joined together by
Answer: glycosidic bonds
The glucose units in starches are joined together by α-1,4 glycosidic bonds.
Starch is made up of two types of polysaccharides: amylose and amylopectin. Amylose is a straight linear chain of glucose molecules linked by α-l,4 glycosidic linkages. Starches have a lengthy, chain-like structure because of the linear arrangement of their -1,4 glycosidic linkages.
Amylopectin is a branched chain of α-d-glucose molecules linked by α-1,6 glycosidic linkage. These bonds are located at the places where the starch molecule branches, and they contribute to the branching structure of starches. Starches are more water soluble than other forms of carbohydrates, such as cellulose, due to their branching structure.
Therefore, In starches, α-1,4 glycosidic linkage bind the glucose units together.
