Answer:
A substance that is more dense per volume has more mass per volume. ...
Explanation:
Thus, sound will travel at a slower rate in the more dense object if they have the same elastic properties.
No one knows. There's no confirmation date at the moment. As that comment said, only time will tell.
Answer:
a. different alleles of the seed shape gene.
Explanation:
Mendel crossed different varieties of pea plants and he observed how phenotypic traits passed to the progeny. From these experiments, Mendel formulated the 'First Law of Segregation', where he observed that traits may exist in pairs that segregate (separate) at meiosis. During meiosis, i.e., gamete formation, these two factors separate from each other, thereby each gamete has the same probability of receiving either factor. Nowadays, we know that these two factors represent two different gene variants or 'alleles' for a given gene <em>locus</em>. Alleles can be classified into dominant or recessive as in the example above described, where the R factor (round) dominates on the r factor (wrinkled) to determine the seed shape.
Life and death are complex things. Life is the existence of something and death is the end. They go hand in hand. Without one you cannot have the other. To live means to die and to die means you have lived.
Hopes this helps. Add a comment if not and I will try to assist.
